+\label{CatMaintenanceChapter}
+\index[general]{Maintenance!Catalog }
+\index[general]{Catalog Maintenance }
+
+Without proper setup and maintenance, your Catalog may continue to grow
+indefinitely as you run Jobs and backup Files, and/or it may become
+very inefficient and slow. How fast the size of your
+Catalog grows depends on the number of Jobs you run and how many files they
+backup. By deleting records within the database, you can make space available
+for the new records that will be added during the next Job. By constantly
+deleting old expired records (dates older than the Retention period), your
+database size will remain constant.
+
+If you started with the default configuration files, they already contain
+reasonable defaults for a small number of machines (less than 5), so if you
+fall into that case, catalog maintenance will not be urgent if you have a few
+hundred megabytes of disk space free. Whatever the case may be, some knowledge
+of retention periods will be useful.
+\label{Retention}
+
+\section{Setting Retention Periods}
+\index[general]{Setting Retention Periods }
+\index[general]{Periods!Setting Retention }
+
+{\bf Bacula} uses three Retention periods: the {\bf File Retention} period,
+the {\bf Job Retention} period, and the {\bf Volume Retention} period. Of
+these three, the File Retention period is by far the most important in
+determining how large your database will become.
+
+The {\bf File Retention} and the {\bf Job Retention} are specified in each
+Client resource as is shown below. The {\bf Volume Retention} period is
+specified in the Pool resource, and the details are given in the next chapter
+of this manual.
+
+\begin{description}
+
+\item [File Retention = \lt{}time-period-specification\gt{}]
+ \index[general]{File Retention }
+ The File Retention record defines the length of time that Bacula will keep
+File records in the Catalog database. When this time period expires, and if
+{\bf AutoPrune} is set to {\bf yes}, Bacula will prune (remove) File records
+that are older than the specified File Retention period. The pruning will
+occur at the end of a backup Job for the given Client. Note that the Client
+database record contains a copy of the File and Job retention periods, but
+Bacula uses the current values found in the Director's Client resource to do
+the pruning.
+
+Since File records in the database account for probably 80 percent of the
+size of the database, you should carefully determine exactly what File
+Retention period you need. Once the File records have been removed from
+the database, you will no longer be able to restore individual files
+in a Job. However, with Bacula version 1.37 and later, as long as the
+Job record still exists, you will be able to restore all files in the
+job.
+
+Retention periods are specified in seconds, but as a convenience, there are
+a number of modifiers that permit easy specification in terms of minutes,
+hours, days, weeks, months, quarters, or years on the record. See the
+\ilink{ Configuration chapter}{Time} of this manual for additional details
+of modifier specification.
+
+The default File retention period is 60 days.
+
+\item [Job Retention = \lt{}time-period-specification\gt{}]
+ \index[general]{Job Retention }
+ The Job Retention record defines the length of time that {\bf Bacula}
+will keep Job records in the Catalog database. When this time period
+expires, and if {\bf AutoPrune} is set to {\bf yes} Bacula will prune
+(remove) Job records that are older than the specified Job Retention
+period. Note, if a Job record is selected for pruning, all associated File
+and JobMedia records will also be pruned regardless of the File Retention
+period set. As a consequence, you normally will set the File retention
+period to be less than the Job retention period.
+
+As mentioned above, once the File records are removed from the database,
+you will no longer be able to restore individual files from the Job.
+However, as long as the Job record remains in the database, you will be
+able to restore all the files backuped for the Job (on version 1.37 and
+later). As a consequence, it is generally a good idea to retain the Job
+records much longer than the File records.
+
+The retention period is specified in seconds, but as a convenience, there
+are a number of modifiers that permit easy specification in terms of
+minutes, hours, days, weeks, months, quarters, or years. See the \ilink{
+Configuration chapter}{Time} of this manual for additional details of
+modifier specification.
+
+The default Job Retention period is 180 days.
+
+\item [AutoPrune = \lt{}yes/no\gt{}]
+ \index[general]{AutoPrune }
+ If AutoPrune is set to {\bf yes} (default), Bacula will automatically apply
+the File retention period and the Job retention period for the Client at the
+end of the Job.
+
+If you turn this off by setting it to {\bf no}, your Catalog will grow each
+time you run a Job.

+\label{CompactingMySQL}
+\section{Compacting Your MySQL Database}
+\index[general]{Database!Compacting Your MySQL }
+\index[general]{Compacting Your MySQL Database }
+
+Over time, as noted above, your database will tend to grow. I've noticed that
+even though Bacula regularly prunes files, {\bf MySQL} does not effectively
+use the space, and instead continues growing. To avoid this, from time to
+time, you must compact your database. Normally, large commercial database such
+as Oracle have commands that will compact a database to reclaim wasted file
+space. MySQL has the {\bf OPTIMIZE TABLE} command that you can use, and SQLite
+version 2.8.4 and greater has the {\bf VACUUM} command. We leave it to you to
+explore the utility of the {\bf OPTIMIZE TABLE} command in MySQL.
+
+All database programs have some means of writing the database out in ASCII
+format and then reloading it. Doing so will re-create the database from
+scratch producing a compacted result, so below, we show you how you can do
+this for MySQL, PostgreSQL and SQLite.
+
+For a {\bf MySQL} database, you could write the Bacula database as an ASCII
+file (bacula.sql) then reload it by doing the following:
+
+\footnotesize
+\begin{verbatim}
+mysqldump -f --opt bacula > bacula.sql
+mysql bacula < bacula.sql
+rm -f bacula.sql
+\end{verbatim}
+\normalsize
+
+Depending on the size of your database, this will take more or less time and a
+fair amount of disk space. For example, if I cd to the location of the MySQL
+Bacula database (typically /opt/mysql/var or something similar) and enter:
+
+\footnotesize
+\begin{verbatim}
+du bacula
+\end{verbatim}
+\normalsize
+
+I get {\bf 620,644} which means there are that many blocks containing 1024
+bytes each or approximately 635 MB of data. After doing the {\bf mysqldump}, I
+had a bacula.sql file that had {\bf 174,356} blocks, and after doing the {\bf
+mysql} command to recreate the database, I ended up with a total of {\bf
+210,464} blocks rather than the original {\bf 629,644}. In other words, the
+compressed version of the database took approximately one third of the space
+of the database that had been in use for about a year.
+
+As a consequence, I suggest you monitor the size of your database and from
+time to time (once every six months or year), compress it.

+\index[general]{Repairing Your MySQL Database }
+
+If you find that you are getting errors writing to your MySQL database, or
+Bacula hangs each time it tries to access the database, you should consider
+running MySQL's database check and repair routines. The program you need to
+run depends on the type of database indexing you are using. If you are using
+the default, you will probably want to use {\bf myisamchk}. For more details
+on how to do this, please consult the MySQL document at:
+\elink{
+http://www.mysql.com/doc/en/Repair.html}
+{http://www.mysql.com/doc/en/Repair.html}.
+
+If the errors you are getting are simply SQL warnings, then you might try
+running dbcheck before (or possibly after) using the MySQL database repair
+program. It can clean up many of the orphaned record problems, and certain
+other inconsistencies in the Bacula database.
+
+A typical cause of MySQL database problems is if your partition fills. In
+such a case, you will need to create additional space on the partition or
+free up some space then repair the database probably using {\bf myisamchk}.
+Recently my root partition filled and the MySQL database was corrupted.
+Simply running {\bf myisamchk -r} did not fix the problem. However,
+the following script did the trick for me:
+
+\footnotesize
+\begin{verbatim}
+#!/bin/sh
+for i in *.MYD ; do
+ mv $i x${i}
+ t=`echo $i | cut -f 1 -d '.' -`
+ mysql bacula <<END_OF_DATA
+set autocommit=1;
+truncate table $t;
+quit
+END_OF_DATA
+ cp x${i} ${i}
+ chown mysql:mysql ${i}
+ myisamchk -r ${t}
+done
+\end{verbatim}
+\normalsize
+
+I invoked it with the following commands:
+
+\footnotesize
+\begin{verbatim}
+cd /var/lib/mysql/bacula
+./repair
+\end{verbatim}
+\normalsize
+
+Then after ensuring that the database was correctly fixed, I did:
+\footnotesize
+\begin{verbatim}
+cd /var/lib/mysql/bacula
+rm -f x*.MYD
+\end{verbatim}
+\normalsize
+
+\section{MySQL Table is Full}
+\index[general]{Database!MySQL Table is Full}
+\index[general]{MySQL Table is Full}
+
+If you are running into the error {\bf The table 'File' is full ...},
+it is probably because on version 4.x MySQL, the table is limited by
+default to a maximum size of 4 GB and you have probably run into
+the limit. The solution can be found at:
+\elink{http://dev.mysql.com/doc/refman/5.0/en/full-table.html}
+{http://dev.mysql.com/doc/refman/5.0/en/full-table.html}
+
+You can display the maximum length of your table with:
+
+\footnotesize
+\begin{verbatim}
+mysql bacula
+SHOW TABLE STATUS FROM bacula like "File";
+\end{verbatim}
+\normalsize
+
+If the column labeled "Max\_data\_length" is around 4Gb, this is likely
+to be the source of your problem, and you can modify it with:
+
+\footnotesize
+\begin{verbatim}
+mysql bacula
+ALTER TABLE File MAX_ROWS=281474976710656;
+\end{verbatim}
+\normalsize
+
+Alternatively you can modify your /etc/my.conf file before creating the
+Bacula tables, and in the [mysqld] section set:
+
+\footnotesize
+\begin{verbatim}
+set-variable = myisam_data_pointer_size=6
+\end{verbatim}
+\normalsize
+
+The above myisam data pointer size must be made before you create your
+Bacula tables or it will have no effect.
+
+The row and pointer size changes should already be the default on MySQL
+version 5.x, so making these changes should only be necessary on MySQL 4.x
+depending on the size of your catalog database.

+The same considerations apply that are indicated above for MySQL. That is,
+consult the PostgreSQL documents for how to repair the database, and also
+consider using Bacula's dbcheck program if the conditions are reasonable for
+using (see above).

+\label{DatabasePerformance}
+\section{Database Performance Issues}
+\index[general]{Database Performance Issues}
+\index[general]{Performance!Database}
+
+There are a considerable number of ways each of the databases can be
+tuned to improve the performance. Going from an untuned database to one
+that is properly tuned can make a difference of a factor of 100 or more
+in the time to insert or search for records.
+
+For each of the databases, you may get significant improvements by adding
+additional indexes. The comments in the Bacula make\_xxx\_tables give some
+indications as to what indexes may be appropriate. Please see below
+for specific instructions on checking indexes.
+
+For MySQL, what is very important is to use the examine the
+my.cnf file (usually in /etc/my.cnf).
+You may obtain significant performances by switching to
+the my-large.cnf or my-huge.cnf files that come with the MySQL source
+code.
+
+For SQLite3, one significant factor in improving the performance is
+to ensure that there is a "PRAGMA synchronous = NORMAL;" statement.
+This reduces the number of times that the database flushes the in memory
+cache to disk. There are other settings for this PRAGMA that can
+give even further performance improvements at the risk of a database
+corruption if your system crashes.
+
+For PostgreSQL, you might want to consider turning fsync off. Of course
+doing so can cause corrupted databases in the event of a machine crash.
+There are many different ways that you can tune PostgreSQL, the
+following document discusses a few of them:
+\elink{
+http://www.varlena.com/varlena/GeneralBits/Tidbits/perf.html}
+{http://www.varlena.com/varlena/GeneralBits/Tidbits/perf.html}.
+
+There is also a PostgreSQL FAQ question number 3.3 that may
+answer some of your questions about how to improve performance
+of the PostgreSQL engine:
+\elink{
+http://www.postgresql.org/docs/faqs.FAQ.html\#3.3}
+{http://www.postgresql.org/docs/faqs.FAQ.html\#3.3}.
+% TODO: verify above is correct. is this okay for book?
+
+Also for PostgreSQL, look at what "effective\_cache\_size". For a 2GB memory
+machine, you probably want to set it at 131072, but don't set it too high.
+In addition, for a 2GB system, work\_mem = 256000 and
+maintenance\_work\_mem = 256000 seem to be reasonable values. Make
+sure your checkpoint\_segments is set to at least 8.
+
+
+
+\section{Performance Issues Indexes}
+\index[general]{Database Performance Issues Indexes}
+\index[general]{Performance!Database}
+One of the most important considerations for improving performance on
+the Bacula database is to ensure that it has all the appropriate indexes.
+Several users have reported finding that their database did not have
+all the indexes in the default configuration. In addition, you may
+find that because of your own usage patterns, you need additional indexes.
+
+The most important indexes for performance are the three indexes on the
+{\bf File} table. The first index is on {\bf FileId} and is automatically
+made because it is the unique key used to access the table. The other
+two are the JobId index and the (Filename, PathId) index. If these Indexes
+are not present, your performance may suffer a lot.
+
+\subsection{PostgreSQL Indexes}
+On PostgreSQL, you can check to see if you have the proper indexes using
+the following commands:
+
+\footnotesize
+\begin{verbatim}
+psql bacula
+select * from pg_indexes where tablename='file';
+\end{verbatim}
+\normalsize
+
+If you do not see output that indicates that all three indexes
+are created, you can create the two additional indexes using:
+
+\footnotesize
+\begin{verbatim}
+psql bacula
+CREATE INDEX file_jobid_idx on file (jobid);
+CREATE INDEX file_fp_idx on file (filenameid, pathid);
+\end{verbatim}
+\normalsize
+
+\subsection{MySQL Indexes}
+On MySQL, you can check if you have the proper indexes by:
+
+\footnotesize
+\begin{verbatim}
+mysql bacula
+show index from File;
+\end{verbatim}
+\normalsize
+
+If the indexes are not present, especially the JobId index, you can
+create them with the following commands:
+
+\footnotesize
+\begin{verbatim}
+mysql bacula
+CREATE INDEX file_jobid_idx on File (JobId);
+CREATE INDEX file_jpf_idx on File (JobId, FilenameId, PathId);
+\end{verbatim}
+\normalsize
+
+Though normally not a problem, you should ensure that the indexes
+defined for Filename and Path are both set to 255 characters. Some users
+reported performance problems when their indexes were set to 50 characters.
+To check, do:
+
+\footnotesize
+\begin{verbatim}
+mysql bacula
+show index from Filename;
+show index from Path;
+\end{verbatim}
+\normalsize
+
+and what is important is that for Filename, you have an index with
+Key\_name "Name" and Sub\_part "255". For Path, you should have a Key\_name
+"Path" and Sub\_part "255". If one or the other does not exist or the
+Sub\_part is less that 255, you can drop and recreate the appropriate
+index with:
+
+\footnotesize
+\begin{verbatim}
+mysql bacula
+DROP INDEX Path on Path;
+CREATE INDEX Path on Path (Path(255);
+
+DROP INDEX Name on Filename;
+CREATE INDEX Name on Filename (Name(255));
+\end{verbatim}
+\normalsize
+
+
+\subsection{SQLite Indexes}
+On SQLite, you can check if you have the proper indexes by:
+
+\footnotesize
+\begin{verbatim}
+sqlite <path>/bacula.db
+select * from sqlite_master where type='index' and tbl_name='File';
+\end{verbatim}
+\normalsize
+
+If the indexes are not present, especially the JobId index, you can
+create them with the following commands:
+
+\footnotesize
+\begin{verbatim}
+sqlite <path>/bacula.db
+CREATE INDEX file_jobid_idx on File (JobId);
+CREATE INDEX file_jfp_idx on File (JobId, FilenameId, PathId);
+\end{verbatim}
+\normalsize

+\label{CompactingPostgres}
+\section{Compacting Your PostgreSQL Database}
+\index[general]{Database!Compacting Your PostgreSQL }
+\index[general]{Compacting Your PostgreSQL Database }
+
+Over time, as noted above, your database will tend to grow. I've noticed that
+even though Bacula regularly prunes files, PostgreSQL has a {\bf VACUUM}
+command that will compact your database for you. Alternatively you may want to
+use the {\bf vacuumdb} command, which can be run from a cron job.
+
+All database programs have some means of writing the database out in ASCII
+format and then reloading it. Doing so will re-create the database from
+scratch producing a compacted result, so below, we show you how you can do
+this for PostgreSQL.
+
+For a {\bf PostgreSQL} database, you could write the Bacula database as an
+ASCII file (bacula.sql) then reload it by doing the following:
+
+\footnotesize
+\begin{verbatim}
+pg_dump -c bacula > bacula.sql
+cat bacula.sql | psql bacula
+rm -f bacula.sql
+\end{verbatim}
+\normalsize
+
+Depending on the size of your database, this will take more or less time and a
+fair amount of disk space. For example, you can {\bf cd} to the location of
+the Bacula database (typically /usr/local/pgsql/data or possible
+/var/lib/pgsql/data) and check the size.
+
+There are certain PostgreSQL users who do not recommend the above
+procedure. They have the following to say:
+PostgreSQL does not
+need to be dumped/restored to keep the database efficient. A normal
+process of vacuuming will prevent the database from every getting too
+large. If you want to fine-tweak the database storage, commands such
+as VACUUM FULL, REINDEX, and CLUSTER exist specifically to keep you
+from having to do a dump/restore.
+
+Finally, you might want to look at the PostgreSQL documentation on
+this subject at
+\elink{http://www.postgresql.org/docs/8.1/interactive/maintenance.html}
+{http://www.postgresql.org/docs/8.1/interactive/maintenance.html}.
+
+\section{Compacting Your SQLite Database}
+\index[general]{Compacting Your SQLite Database }
+\index[general]{Database!Compacting Your SQLite }
+
+First please read the previous section that explains why it is necessary to
+compress a database. SQLite version 2.8.4 and greater have the {\bf Vacuum}
+command for compacting the database.
+
+\footnotesize
+\begin{verbatim}
+cd {\bf working-directory}
+echo 'vacuum;' | sqlite bacula.db
+\end{verbatim}
+\normalsize
+
+As an alternative, you can use the following commands, adapted to your system:
+
+
+\footnotesize
+\begin{verbatim}
+cd {\bf working-directory}
+echo '.dump' | sqlite bacula.db > bacula.sql
+rm -f bacula.db
+sqlite bacula.db < bacula.sql
+rm -f bacula.sql
+\end{verbatim}
+\normalsize
+
+Where {\bf working-directory} is the directory that you specified in the
+Director's configuration file. Note, in the case of SQLite, it is necessary to
+completely delete (rm) the old database before creating a new compressed
+version.
+
+\section{Migrating from SQLite to MySQL or PostgreSQL}
+\index[general]{MySQL!Migrating from SQLite to }
+\index[general]{Migrating from SQLite to MySQL or PostgreSQL}
+
+You may begin using Bacula with SQLite then later find that you want to switch
+to MySQL or Postgres for any of a number of reasons: SQLite tends to use more
+disk than MySQL; when the database is corrupted it is often more catastrophic
+than with MySQL or PostgreSQL. Several users have succeeded in converting by
+exporting the SQLite data and then processing it with Perl scripts prior to
+putting it into MySQL or PostgreSQL. This is, however, not a simple process.
+Scripts are available on bacula source distribution under
+\texttt{examples/database}.

+\label{BackingUpBacula}
+\section{Backing Up Your Bacula Database}
+\index[general]{Backing Up Your Bacula Database }
+\index[general]{Database!Backing Up Your Bacula }
+
+If ever the machine on which your Bacula database crashes, and you need to
+restore from backup tapes, one of your first priorities will probably be to
+recover the database. Although Bacula will happily backup your catalog
+database if it is specified in the FileSet, this is not a very good way to do
+it, because the database will be saved while Bacula is modifying it. Thus the
+database may be in an instable state. Worse yet, you will backup the database
+before all the Bacula updates have been applied.
+
+To resolve these problems, you need to backup the database after all the backup
+jobs have been run. In addition, you will want to make a copy while Bacula is
+not modifying it. To do so, you can use two scripts provided in the release
+{\bf make\_catalog\_backup} and {\bf delete\_catalog\_backup}. These files
+will be automatically generated along with all the other Bacula scripts. The
+first script will make an ASCII copy of your Bacula database into {\bf
+bacula.sql} in the working directory you specified in your configuration, and
+the second will delete the {\bf bacula.sql} file.
+
+The basic sequence of events to make this work correctly is as follows:
+
+\begin{itemize}
+\item Run all your nightly backups
+\item After running your nightly backups, run a Catalog backup Job
+\item The Catalog backup job must be scheduled after your last nightly backup
+
+\item You use {\bf RunBeforeJob} to create the ASCII backup file and {\bf
+ RunAfterJob} to clean up
+\end{itemize}
+
+Assuming that you start all your nightly backup jobs at 1:05 am (and that they
+run one after another), you can do the catalog backup with the following
+additional Director configuration statements:
+
+\footnotesize
+\begin{verbatim}
+# Backup the catalog database (after the nightly save)
+Job {
+ Name = "BackupCatalog"
+ Type = Backup
+ Client=rufus-fd
+ FileSet="Catalog"
+ Schedule = "WeeklyCycleAfterBackup"
+ Storage = DLTDrive
+ Messages = Standard
+ Pool = Default
+ # WARNING!!! Passing the password via the command line is insecure.
+ # see comments in make_catalog_backup for details.
+ RunBeforeJob = "/home/kern/bacula/bin/make_catalog_backup"
+ RunAfterJob = "/home/kern/bacula/bin/delete_catalog_backup"
+ Write Bootstrap = "/home/kern/bacula/working/BackupCatalog.bsr"
+}
+# This schedule does the catalog. It starts after the WeeklyCycle
+Schedule {
+ Name = "WeeklyCycleAfterBackup
+ Run = Level=Full sun-sat at 1:10
+}
+# This is the backup of the catalog
+FileSet {
+ Name = "Catalog"
+ Include {
+ Options {
+ signature=MD5
+ }
+ File = \lt{}working_directory\gt{}/bacula.sql
+ }
+}
+\end{verbatim}
+\normalsize
+
+Be sure to write a bootstrap file as in the above example. However, it is preferable
+to write or copy the bootstrap file to another computer. It will allow
+you to quickly recover the database backup should that be necessary. If
+you do not have a bootstrap file, it is still possible to recover your
+database backup, but it will be more work and take longer.
+

+
+We provide make\_catalog\_backup as an example of what can be used to backup
+your Bacula database. We expect you to take security precautions relevant
+to your situation. make\_catalog\_backup is designed to take a password on
+the command line. This is fine on machines with only trusted users. It is
+not acceptable on machines without trusted users. Most database systems
+provide a alternative method, which does not place the password on the
+command line.
+
+The make\_catalog\_backup script contains some warnings about how to use it. Please

+
+To help you get started, we know PostgreSQL has a password file,

+\section{Backing Up Third Party Databases}
+\index[general]{Backing Up Third Party Databases }
+\index[general]{Databases!Backing Up Third Party }
+
+If you are running a database in production mode on your machine, Bacula will
+happily backup the files, but if the database is in use while Bacula is
+reading it, you may back it up in an unstable state.
+
+The best solution is to shutdown your database before backing it up, or use
+some tool specific to your database to make a valid live copy perhaps by
+dumping the database in ASCII format. I am not a database expert, so I cannot
+provide you advice on how to do this, but if you are unsure about how to
+backup your database, you might try visiting the Backup Central site, which
+has been renamed Storage Mountain (www.backupcentral.com). In particular,
+their
+\elink{ Free Backup and Recovery
+Software}{http://www.backupcentral.com/toc-free-backup-software.html} page has
+links to scripts that show you how to shutdown and backup most major
+databases.
+\label{Size}
+
+\section{Database Size}
+\index[general]{Size!Database }
+\index[general]{Database Size }
+
+As mentioned above, if you do not do automatic pruning, your Catalog will grow
+each time you run a Job. Normally, you should decide how long you want File
+records to be maintained in the Catalog and set the {\bf File Retention}
+period to that time. Then you can either wait and see how big your Catalog
+gets or make a calculation assuming approximately 154 bytes for each File
+saved and knowing the number of Files that are saved during each backup and
+the number of Clients you backup.
+
+For example, suppose you do a backup of two systems, each with 100,000 files.
+Suppose further that you do a Full backup weekly and an Incremental every day,
+and that the Incremental backup typically saves 4,000 files. The size of your
+database after a month can roughly be calculated as:
+
+\footnotesize
+\begin{verbatim}
+ Size = 154 * No. Systems * (100,000 * 4 + 10,000 * 26)
+\end{verbatim}
+\normalsize
+
+where we have assumed four weeks in a month and 26 incremental backups per month.
+This would give the following:
+
+\footnotesize
+\begin{verbatim}
+ Size = 154 * 2 * (100,000 * 4 + 10,000 * 26)
+or
+ Size = 308 * (400,000 + 260,000)
+or
+ Size = 203,280,000 bytes
+\end{verbatim}
+\normalsize
+
+So for the above two systems, we should expect to have a database size of
+approximately 200 Megabytes. Of course, this will vary according to how many
+files are actually backed up.
+
+Below are some statistics for a MySQL database containing Job records for five
+Clients beginning September 2001 through May 2002 (8.5 months) and File
+records for the last 80 days. (Older File records have been pruned). For these
+systems, only the user files and system files that change are backed up. The
+core part of the system is assumed to be easily reloaded from the Red Hat rpms.
+
+
+In the list below, the files (corresponding to Bacula Tables) with the
+extension .MYD contain the data records whereas files with the extension .MYI
+contain indexes.
+
+You will note that the File records (containing the file attributes) make up
+the large bulk of the number of records as well as the space used (459 Mega
+Bytes including the indexes). As a consequence, the most important Retention
+period will be the {\bf File Retention} period. A quick calculation shows that
+for each File that is saved, the database grows by approximately 150 bytes.
+
+\footnotesize

+
+This database has a total size of approximately 450 Megabytes.
+
+If we were using SQLite, the determination of the total database size would be
+much easier since it is a single file, but we would have less insight to the
+size of the individual tables as we have in this case.
+
+Note, SQLite databases may be as much as 50\% larger than MySQL databases due
+to the fact that all data is stored as ASCII strings. That is even binary
+integers are stored as ASCII strings, and this seems to increase the space
+needed.

+ Version 1.2, November 2002
+
+
+ Copyright \copyright 2000,2001,2002 Free Software Foundation, Inc.
+
+ \bigskip
+
+ 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA

+
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+\end{center}
+
+
+\begin{center}
+{\bf\large Preamble}
+\end{center}
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document "free" in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of "copyleft", which means that derivative
+works of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does. But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book. We recommend this License
+principally for works whose purpose is instruction or reference.
+
+
+\begin{center}
+{\Large\bf 1. APPLICABILITY AND DEFINITIONS}
+\end{center}
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License. Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein. The \textbf{"Document"}, below,
+refers to any such manual or work. Any member of the public is a
+licensee, and is addressed as \textbf{"you"}. You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A \textbf{"Modified Version"} of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A \textbf{"Secondary Section"} is a named appendix or a front-matter section of
+the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall subject
+(or to related matters) and contains nothing that could fall directly
+within that overall subject. (Thus, if the Document is in part a
+textbook of mathematics, a Secondary Section may not explain any
+mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The \textbf{"Invariant Sections"} are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License. If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant. The Document may contain zero
+Invariant Sections. If the Document does not identify any Invariant
+Sections then there are none.
+
+The \textbf{"Cover Texts"} are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License. A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A \textbf{"Transparent"} copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text. A copy that is not "Transparent" is called \textbf{"Opaque"}.
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input format, SGML
+or XML using a publicly available DTD, and standard-conforming simple
+HTML, PostScript or PDF designed for human modification. Examples of
+transparent image formats include PNG, XCF and JPG. Opaque formats
+include proprietary formats that can be read and edited only by
+proprietary word processors, SGML or XML for which the DTD and/or
+processing tools are not generally available, and the
+machine-generated HTML, PostScript or PDF produced by some word
+processors for output purposes only.
+
+The \textbf{"Title Page"} means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, "Title Page" means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+A section \textbf{"Entitled XYZ"} means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language. (Here XYZ stands for a
+specific section name mentioned below, such as \textbf{"Acknowledgements"},
+\textbf{"Dedications"}, \textbf{"Endorsements"}, or \textbf{"History"}.)
+To \textbf{"Preserve the Title"}
+of such a section when you modify the Document means that it remains a
+section "Entitled XYZ" according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document. These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+
+\begin{center}
+{\Large\bf 2. VERBATIM COPYING}
+\end{center}
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+
+\begin{center}
+{\Large\bf 3. COPYING IN QUANTITY}
+\end{center}
+
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+
+\begin{center}
+{\Large\bf 4. MODIFICATIONS}
+\end{center}
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+\begin{itemize}
+\item[A.]
+ Use in the Title Page (and on the covers, if any) a title distinct
+ from that of the Document, and from those of previous versions
+ (which should, if there were any, be listed in the History section
+ of the Document). You may use the same title as a previous version
+ if the original publisher of that version gives permission.
+
+\item[B.]
+ List on the Title Page, as authors, one or more persons or entities
+ responsible for authorship of the modifications in the Modified
+ Version, together with at least five of the principal authors of the
+ Document (all of its principal authors, if it has fewer than five),
+ unless they release you from this requirement.
+
+\item[C.]
+ State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+
+\item[D.]
+ Preserve all the copyright notices of the Document.
+
+\item[E.]
+ Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+
+\item[F.]
+ Include, immediately after the copyright notices, a license notice
+ giving the public permission to use the Modified Version under the
+ terms of this License, in the form shown in the Addendum below.
+
+\item[G.]
+ Preserve in that license notice the full lists of Invariant Sections
+ and required Cover Texts given in the Document's license notice.
+
+\item[H.]
+ Include an unaltered copy of this License.
+
+\item[I.]
+ Preserve the section Entitled "History", Preserve its Title, and add
+ to it an item stating at least the title, year, new authors, and
+ publisher of the Modified Version as given on the Title Page. If
+ there is no section Entitled "History" in the Document, create one
+ stating the title, year, authors, and publisher of the Document as
+ given on its Title Page, then add an item describing the Modified
+ Version as stated in the previous sentence.
+
+\item[J.]
+ Preserve the network location, if any, given in the Document for
+ public access to a Transparent copy of the Document, and likewise
+ the network locations given in the Document for previous versions
+ it was based on. These may be placed in the "History" section.
+ You may omit a network location for a work that was published at
+ least four years before the Document itself, or if the original
+ publisher of the version it refers to gives permission.
+
+\item[K.]
+ For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the section all
+ the substance and tone of each of the contributor acknowledgements
+ and/or dedications given therein.
+
+\item[L.]
+ Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section titles.
+
+\item[M.]
+ Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+
+\item[N.]
+ Do not retitle any existing section to be Entitled "Endorsements"
+ or to conflict in title with any Invariant Section.
+
+\item[O.]
+ Preserve any Warranty Disclaimers.
+\end{itemize}
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled "Endorsements", provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+
+\begin{center}
+{\Large\bf 5. COMBINING DOCUMENTS}
+\end{center}
+
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled "History"
+in the various original documents, forming one section Entitled
+"History"; likewise combine any sections Entitled "Acknowledgements",
+and any sections Entitled "Dedications". You must delete all sections
+Entitled "Endorsements".
+
+\begin{center}
+{\Large\bf 6. COLLECTIONS OF DOCUMENTS}
+\end{center}
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+
+\begin{center}
+{\Large\bf 7. AGGREGATION WITH INDEPENDENT WORKS}
+\end{center}
+
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an "aggregate" if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+
+\begin{center}
+{\Large\bf 8. TRANSLATION}
+\end{center}
+
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers. In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled "Acknowledgements",
+"Dedications", or "History", the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+
+\begin{center}
+{\Large\bf 9. TERMINATION}
+\end{center}
+
+
+You may not copy, modify, sublicense, or distribute the Document except
+as expressly provided for under this License. Any other attempt to
+copy, modify, sublicense or distribute the Document is void, and will
+automatically terminate your rights under this License. However,
+parties who have received copies, or rights, from you under this
+License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+
+\begin{center}
+{\Large\bf 10. FUTURE REVISIONS OF THIS LICENSE}
+\end{center}
+
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns. See
+http://www.gnu.org/copyleft/.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation. If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.
+
+
+\begin{center}
+{\Large\bf ADDENDUM: How to use this License for your documents}
+% TODO: this is too long for table of contents
+\end{center}
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+\bigskip
+\begin{quote}
+ Copyright \copyright YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.2
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
+ A copy of the license is included in the section entitled "GNU
+ Free Documentation License".
+\end{quote}
+\bigskip
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the "with...Texts." line with this:
+
+\bigskip
+\begin{quote}
+ with the Invariant Sections being LIST THEIR TITLES, with the
+ Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
+\end{quote}
+\bigskip
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

+# 14-Mar-2005 -- Clarified and Consolodated some of the code.
+# Changed to smoothly handle single and multiple indices.
+
+# Two LaTeX index formats are supported...

+# ___________________
+#
+# For the multiple-index style, each index is identified by the ref argument to \newindex, \index,
+# and \printindex. A default index is allowed, which is indicated by omitting the optional
+# argument. The default index does not require a \newindex command. As \index commands
+# are encountered, their entries are stored according
+# to the ref argument. When the \printindex command is encountered, the stored index
+# entries for that argument are retrieved and printed. The title for each index is taken
+# from the last argument in the \newindex command.
+# While processing \index and \printindex commands, if no argument is given the index entries
+# are built into a default index. The title of the default index is simply "Index".
+# This makes the difference between single- and multiple-index processing trivial.
+#
+# Another method can be used by omitting the \printindex command and just using \include to
+# pull in index files created by the makeindex program. These files will start with
+# \begin{theindex}. This command is used to determine where to print the index. Using this
+# approach, the indices will be output in the same order as the newindex commands were
+# originally found (see below). Using a combination of \printindex and \include{indexfile} has not
+# been tested and may produce undesireable results.
+#
+# The index data are stored in a hash for later sorting and output. As \printindex
+# commands are handled, the order in which they were found in the tex filea is saved,
+# associated with the ref argument to \printindex.
+#
+# We use the original %index hash to store the index data into. We append a \002 followed by the
+# name of the index to isolate the entries in different indices from each other. This is necessary
+# so that different indices can have entries with the same name. For the default index, the \002 is
+# appended without the name.
+#
+# Since the index order in the output cannot be determined if the \include{indexfile}
+# command is used, the order will be assumed from the order in which the \newindex
+# commands were originally seen in the TeX files. This order is saved as well as the
+# order determined from any printindex{ref} commands. If \printindex commnads are used
+# to specify the index output, that order will be used. If the \include{idxfile} command
+# is used, the order of the original newindex commands will be used. In this case the
+# default index will be printed last since it doesn't have a corresponding \newindex
+# command and its order cannot be determined. Mixing \printindex and \include{idxfile}
+# commands in the same file is likely to produce less than satisfactory results.
+#
+#
+# The hash containing index data is named %indices. It contains the following data:
+#{
+# 'title' => {
+# $ref1 => $indextitle ,
+# $ref2 => $indextitle ,
+# ...
+# },
+# 'newcmdorder' => [ ref1, ref2, ..., * ], # asterisk indicates the position of the default index.
+# 'printindorder' => [ ref1, ref2, ..., * ], # asterisk indicates the position of the default index.

+
+This database is simplistic in that it consists entirely of Bacula's internal

+inappropriate for sites with many clients or systems with large numbers of
+files, or long-term production environments.
+
+Below, you will find a table comparing the features available with SQLite and
+MySQL and with the internal Bacula database. At the current time, you cannot

+
+\section{Installing and Configuring MySQL -- Phase I}
+\index[general]{Installing and Configuring MySQL -- Phase I }
+\index[general]{Phase I!Installing and Configuring MySQL -- }
+
+If you use the ./configure \verb:--:with-mysql=mysql-directory statement for
+configuring {\bf Bacula}, you will need MySQL version 4.1 or later installed
+in the {\bf mysql-directory}. If you are using one of the new modes such as
+ANSI/ISO compatibility, you may experience problems.
+
+If MySQL is installed in the standard system location, you need only enter
+{\bf \verb:--:with-mysql} since the configure program will search all the
+standard locations. If you install MySQL in your home directory or some
+other non-standard directory, you will need to provide the full path to it.
+
+Installing and Configuring MySQL is not difficult but can be confusing the
+first time. As a consequence, below, we list the steps that we used to install
+it on our machines. Please note that our configuration leaves MySQL without
+any user passwords. This may be an undesirable situation if you have other
+users on your system.
+
+The notes below describe how to build MySQL from the source tar files. If
+you have a pre-installed MySQL, you can return to complete the installation
+of Bacula, then come back to Phase II of the MySQL installation. If you
+wish to install MySQL from rpms, you will probably need to install
+the following:
+
+\footnotesize
+\begin{verbatim}
+mysql-<version>.rpm
+mysql-server-<version>.rpm
+mysql-devel-<version>.rpm
+\end{verbatim}
+\normalsize
+The names of the packages may vary from distribution to
+distribution. It is important to have the devel package loaded as
+it contains the libraries and header files necessary to build
+Bacula. There may be additional packages that are required to
+install the above, for example, zlib and openssl.
+
+Once these packages are installed, you will be able to build Bacula (using
+the files installed with the mysql package, then run MySQL using the
+files installed with mysql-server. If you have installed MySQL by rpms,
+please skip Phase I below, and return to complete the installation of
+Bacula, then come back to Phase II of the MySQL installation when indicated
+to do so.
+
+Beginning with Bacula version 1.31, the thread safe version of the
+MySQL client library is used, and hence you should add the {\bf
+\verb:--:enable-thread-safe-client} option to the {\bf
+./configure} as shown below:
+
+\begin{enumerate}
+\item Download MySQL source code from
+ \elink{www.mysql.com/downloads}{http://www.mysql.com/downloads}
+
+\item Detar it with something like:
+
+ {\bf tar xvfz mysql-filename}
+
+Note, the above command requires GNU tar. If you do not have GNU tar, a
+command such as:
+
+{\bf zcat mysql-filename | tar xvf - }
+
+will probably accomplish the same thing.
+
+\item cd {\bf mysql-source-directory}
+
+ where you replace {\bf mysql-source-directory} with the directory name where
+ you put the MySQL source code.
+
+\item ./configure \verb:--:enable-thread-safe-client \verb:--:prefix=mysql-directory
+
+ where you replace {\bf mysql-directory} with the directory name where you
+ want to install mysql. Normally for system wide use this is /usr/local/mysql.
+ In my case, I use \~{}kern/mysql.
+
+\item make
+
+ This takes a bit of time.
+
+\item make install
+
+ This will put all the necessary binaries, libraries and support files into
+ the {\bf mysql-directory} that you specified above.
+
+\item ./scripts/mysql\_install\_db
+
+ This will create the necessary MySQL databases for controlling user access.
+Note, this script can also be found in the {\bf bin} directory in the
+installation directory
+
+\end{enumerate}
+
+The MySQL client library {\bf mysqlclient} requires the gzip compression
+library {\bf libz.a} or {\bf libz.so}. If you are using rpm packages, these
+libraries are in the {\bf libz-devel} package. On Debian systems, you will
+need to load the {\bf zlib1g-dev} package. If you are not using rpms or debs,
+you will need to find the appropriate package for your system.
+
+At this point, you should return to completing the installation of {\bf
+Bacula}. Later after Bacula is installed, come back to this chapter to
+complete the installation. Please note, the installation files used in the
+second phase of the MySQL installation are created during the Bacula
+Installation.
+
+\label{mysql_phase2}
+\section{Installing and Configuring MySQL -- Phase II}
+\index[general]{Installing and Configuring MySQL -- Phase II }
+\index[general]{Phase II!Installing and Configuring MySQL -- }
+
+At this point, you should have built and installed MySQL, or already have a
+running MySQL, and you should have configured, built and installed {\bf
+Bacula}. If not, please complete these items before proceeding.
+
+Please note that the {\bf ./configure} used to build {\bf Bacula} will need to
+include {\bf \verb:--:with-mysql=mysql-directory}, where {\bf mysql-directory} is the
+directory name that you specified on the ./configure command for configuring
+MySQL. This is needed so that Bacula can find the necessary include headers
+and library files for interfacing to MySQL.
+
+{\bf Bacula} will install scripts for manipulating the database (create,
+delete, make tables etc) into the main installation directory. These files
+will be of the form *\_bacula\_* (e.g. create\_bacula\_database). These files
+are also available in the \lt{}bacula-src\gt{}/src/cats directory after
+running ./configure. If you inspect create\_bacula\_database, you will see
+that it calls create\_mysql\_database. The *\_bacula\_* files are provided for
+convenience. It doesn't matter what database you have chosen;
+create\_bacula\_database will always create your database.
+
+Now you will create the Bacula MySQL database and the tables that Bacula uses.
+
+
+\begin{enumerate}
+\item Start {\bf mysql}. You might want to use the {\bf startmysql} script
+ provided in the Bacula release.
+
+\item cd \lt{}install-directory\gt{}
+ This directory contains the Bacula catalog interface routines.
+
+\item ./grant\_mysql\_privileges
+ This script creates unrestricted access rights for the user {\bf bacula}.
+ You may want to modify it to suit your situation. Please
+ note that none of the userids, including root, are password protected.
+ If you need more security, please assign a password to the root user
+ and to bacula. The program {\bf mysqladmin} can be used for this.
+
+\item ./create\_mysql\_database
+ This script creates the MySQL {\bf bacula} database. The databases you
+ create as well as the access databases will be located in
+ \lt{}install-dir\gt{}/var/ in a subdirectory with the name of the
+ database, where \lt{}install-dir\gt{} is the directory name that you
+ specified on the {\bf \verb:--:prefix} option. This can be important to
+ know if you want to make a special backup of the Bacula database or to
+ check its size.
+
+\item ./make\_mysql\_tables
+ This script creates the MySQL tables used by {\bf Bacula}.
+\end{enumerate}
+
+Each of the three scripts (grant\_mysql\_privileges, create\_mysql\_database
+and make\_mysql\_tables) allows the addition of a command line argument. This
+can be useful for specifying the user and or password. For example, you might
+need to add {\bf -u root} to the command line to have sufficient privilege to
+create the Bacula tables.
+
+To take a closer look at the access privileges that you have setup with the
+above, you can do:
+
+\footnotesize
+\begin{verbatim}
+mysql-directory/bin/mysql -u root mysql
+select * from user;
+\end{verbatim}
+\normalsize

+\index[general]{Re-initializing the Catalog Database }
+
+After you have done some initial testing with {\bf Bacula}, you will probably
+want to re-initialize the catalog database and throw away all the test Jobs
+that you ran. To do so, you can do the following:
+
+\footnotesize
+\begin{verbatim}
+ cd <install-directory>
+ ./drop_mysql_tables
+ ./make_mysql_tables
+\end{verbatim}
+\normalsize
+
+Please note that all information in the database will be lost and you will be
+starting from scratch. If you have written on any Volumes, you must write an
+end of file mark on the volume so that Bacula can reuse it. Do so with:
+
+\footnotesize
+\begin{verbatim}
+ (stop Bacula or unmount the drive)
+ mt -f /dev/nst0 rewind
+ mt -f /dev/nst0 weof
+\end{verbatim}
+\normalsize
+
+Where you should replace {\bf /dev/nst0} with the appropriate tape drive
+device name for your machine.
+
+\section{Linking Bacula with MySQL}
+\index[general]{Linking Bacula with MySQL }
+\index[general]{MySQL!Linking Bacula with }
+\index[general]{Upgrading}
+
+After configuring Bacula with
+
+./configure \verb:--:enable-thread-safe-client \verb:--:prefix=\lt{}mysql-directory\gt{}
+where \lt{}mysql-directory\gt{} is in my case {\bf /home/kern/mysql}, you may
+have to configure the loader so that it can find the MySQL shared libraries.
+If you have previously followed this procedure and later add the {\bf
+\verb:--:enable-thread-safe-client} options, you will need to rerun the {\bf
+ldconfig} program shown below. If you put MySQL in a standard place such as
+{\bf /usr/lib} or {\bf /usr/local/lib} this will not be necessary, but in my
+case it is. The description that follows is Linux specific. For other
+operating systems, please consult your manuals on how to do the same thing:
+
+First edit: {\bf /etc/ld.so.conf} and add a new line to the end of the file
+with the name of the mysql-directory. In my case, it is:
+
+/home/kern/mysql/lib/mysql then rebuild the loader's cache with:
+
+/sbin/ldconfig If you upgrade to a new version of {\bf MySQL}, the shared
+library names will probably change, and you must re-run the {\bf
+/sbin/ldconfig} command so that the runtime loader can find them.
+
+Alternatively, your system my have a loader environment variable that can be
+set. For example, on a Solaris system where I do not have root permission, I
+use:
+
+LD\_LIBRARY\_PATH=/home/kern/mysql/lib/mysql
+
+Finally, if you have encryption enabled in MySQL, you may need to add {\bf
+-lssl -lcrypto} to the link. In that case, you can either export the
+appropriate LDFLAGS definition, or alternatively, you can include them
+directly on the ./configure line as in:
+
+\footnotesize
+\begin{verbatim}
+LDFLAGS="-lssl -lcyrpto" \
+ ./configure \
+ <your-options>
+\end{verbatim}
+\normalsize
+
+\section{Installing MySQL from RPMs}
+\index[general]{MySQL!Installing from RPMs}
+\index[general]{Installing MySQL from RPMs}
+If you are installing MySQL from RPMs, you will need to install
+both the MySQL binaries and the client libraries. The client
+libraries are usually found in a devel package, so you must
+install:
+
+\footnotesize
+\begin{verbatim}
+ mysql
+ mysql-devel
+\end{verbatim}
+\normalsize
+
+This will be the same with most other package managers too.
+
+\section{Upgrading MySQL}
+\index[general]{Upgrading MySQL }
+\index[general]{Upgrading!MySQL }
+\index[general]{Upgrading}
+If you upgrade MySQL, you must reconfigure, rebuild, and re-install
+Bacula otherwise you are likely to get bizarre failures. If you
+install from rpms and you upgrade MySQL, you must also rebuild Bacula.
+You can do so by rebuilding from the source rpm. To do so, you may need
+to modify the bacula.spec file to account for the new MySQL version.

+\label{PostgreSqlChapter}
+\index[general]{PostgreSQL!Installing and Configuring }
+\index[general]{Installing and Configuring PostgreSQL }
+\index[general]{Upgrading}
+
+If you are considering using PostreSQL, you should be aware
+of their philosophy of upgrades, which could be
+destabilizing for a production shop. Basically at every major version
+upgrade, you are required to dump your database in an ASCII format,
+do the upgrade, and then reload your database (or databases). This is
+because they frequently update the "data format" from version to
+version, and they supply no tools to automatically do the conversion.
+If you forget to do the ASCII dump, your database may become totally
+useless because none of the new tools can access it due to the format
+change, and the PostgreSQL server will not be able to start.
+
+If you are building PostgreSQL from source, please be sure to add
+the {\bf \verb:--:enable-thread-safety} option when doing the ./configure
+for PostgreSQL.
+
+\section{Installing PostgreSQL}
+\index[general]{PostgreSQL!Installing }
+
+If you use the {\bf ./configure \verb:--:with-postgresql=PostgreSQL-Directory}
+statement for configuring {\bf Bacula}, you will need PostgreSQL version 7.4
+or later installed. NOTE! PostgreSQL versions earlier than 7.4 do not work
+with Bacula. If PostgreSQL is installed in the standard system location, you
+need only enter {\bf \verb:--:with-postgresql} since the configure program will
+search all the standard locations. If you install PostgreSQL in your home
+directory or some other non-standard directory, you will need to provide the
+full path with the {\bf \verb:--:with-postgresql} option.
+
+Installing and configuring PostgreSQL is not difficult but can be confusing
+the first time. If you prefer, you may want to use a package provided by your
+chosen operating system. Binary packages are available on most PostgreSQL
+mirrors.
+
+If you prefer to install from source, we recommend following the instructions
+found in the
+\elink{PostgreSQL documentation}{http://www.postgresql.org/docs/}.
+
+If you are using FreeBSD,
+\elink{this FreeBSD Diary article}{http://www.freebsddiary.org/postgresql.php}
+will be useful. Even if you are not using FreeBSD, the article will contain
+useful configuration and setup information.
+
+If you configure the Batch Insert code in Bacula (attribute inserts are
+10 times faster), you {\bf must} be using a PostgreSQL that was built with
+the {\bf \verb:--:enable-thread-safety} option, otherwise you will get
+data corruption. Most major Linux distros have thread safety turned on, but
+it is better to check. One way is to see if the PostgreSQL library that
+Bacula will be linked against references pthreads. This can be done
+with a command such as:
+
+\footnotesize
+\begin{verbatim}
+ nm /usr/lib/libpq.a | grep pthread_mutex_lock
+\end{verbatim}
+\normalsize
+
+The above command should print a line that looks like:
+
+\footnotesize
+\begin{verbatim}
+ U pthread_mutex_lock
+\end{verbatim}
+\normalsize
+
+if does, then everything is OK. If it prints nothing, do not enable batch
+inserts when building Bacula.
+
+After installing PostgreSQL, you should return to completing the installation
+of {\bf Bacula}. Later, after Bacula is installed, come back to this chapter
+to complete the installation. Please note, the installation files used in the
+second phase of the PostgreSQL installation are created during the Bacula
+Installation. You must still come back to complete the second phase of the
+PostgreSQL installation even if you installed binaries (e.g. rpm, deb,
+...).
+
+
+\label{PostgreSQL_configure}
+\section{Configuring PostgreSQL}
+\index[general]{PostgreSQL!Configuring PostgreSQL -- }
+
+At this point, you should have built and installed PostgreSQL, or already have
+a running PostgreSQL, and you should have configured, built and installed {\bf
+Bacula}. If not, please complete these items before proceeding.
+
+Please note that the {\bf ./configure} used to build {\bf Bacula} will need to
+include {\bf \verb:--:with-postgresql=PostgreSQL-directory}, where {\bf
+PostgreSQL-directory} is the directory name that you specified on the
+./configure command for configuring PostgreSQL (if you didn't specify a
+directory or PostgreSQL is installed in a default location, you do not need to
+specify the directory). This is needed so that Bacula can find the necessary
+include headers and library files for interfacing to PostgreSQL.
+
+{\bf Bacula} will install scripts for manipulating the database (create,
+delete, make tables etc) into the main installation directory. These files
+will be of the form *\_bacula\_* (e.g. create\_bacula\_database). These files
+are also available in the \lt{}bacula-src\gt{}/src/cats directory after
+running ./configure. If you inspect create\_bacula\_database, you will see
+that it calls create\_postgresql\_database. The *\_bacula\_* files are
+provided for convenience. It doesn't matter what database you have chosen;
+create\_bacula\_database will always create your database.
+
+Now you will create the Bacula PostgreSQL database and the tables that Bacula
+uses. These instructions assume that you already have PostgreSQL running. You
+will need to perform these steps as a user that is able to create new
+databases. This can be the PostgreSQL user (on most systems, this is the pgsql
+user).
+
+\begin{enumerate}
+\item cd \lt{}install-directory\gt{}
+
+ This directory contains the Bacula catalog interface routines.
+
+\item ./create\_bacula\_database
+
+ This script creates the PostgreSQL {\bf bacula} database.
+ Before running this command, you should carefully think about
+ what encoding sequence you want for the text fields (paths, files, ...).
+ Ideally, the encoding should be set to UTF8. However, many Unix systems
+ have filenames that are not encoded in UTF8, either because you have
+ not set UTF8 as your default character set or because you have imported
+ files from elsewhere (e.g. MacOS X). For this reason, Bacula uses
+ SQL\_ASCII as the default encoding. If you want to change this,
+ please modify the script before running it, but be forewarned that
+ Bacula backups will fail if PostgreSQL finds any non-UTF8 sequences.
+
+ If running the script fails, it is probably because the database is
+ owned by a user other than yourself. On many systems, the database
+ owner is {\bf pgsql} and on others such as Red Hat and Fedora it is {\bf
+ postgres}. You can find out which it is by examining your /etc/passwd
+ file. To create a new user under either your name or with say the name
+ {\bf bacula}, you can do the following:
+
+\begin{verbatim}
+ su
+ (enter root password)
+ su pgsql (or postgres)
+ createuser kern (or perhaps bacula)
+ Shall the new user be allowed to create databases? (y/n) y
+ Shall the new user be allowed to create more new users? (y/n) (choose
+ what you want)
+ exit
+\end{verbatim}
+
+ At this point, you should be able to execute the
+ ./create\_bacula\_database command.
+
+\item ./make\_bacula\_tables
+
+ This script creates the PostgreSQL tables used by {\bf Bacula}.
+\item ./grant\_bacula\_privileges
+
+ This script creates the database user {\bf bacula} with restricted access
+rights. You may want to modify it to suit your situation. Please note that
+this database is not password protected.
+
+\end{enumerate}
+
+Each of the three scripts (create\_bacula\_database, make\_bacula\_tables, and
+grant\_bacula\_privileges) allows the addition of a command line argument.
+This can be useful for specifying the user name. For example, you might need
+to add {\bf -h hostname} to the command line to specify a remote database
+server.
+
+To take a closer look at the access privileges that you have setup with the
+above, you can do:
+
+\footnotesize
+\begin{verbatim}
+PostgreSQL-directory/bin/psql --command \\dp bacula
+\end{verbatim}
+\normalsize
+
+Also, I had an authorization problem with the password. In the end,
+I had to modify my {\bf pg\_hba.conf} file (in /var/lib/pgsql/data on my machine)
+from:
+
+\footnotesize
+\begin{verbatim}
+ local all all ident sameuser
+to
+ local all all trust
+\end{verbatim}
+\normalsize
+
+This solved the problem for me, but it is not always a good thing
+to do from a security standpoint. However, it allowed me to run
+my regression scripts without having a password.
+
+A more secure way to perform database authentication is with md5
+password hashes. Begin by editing the {\bf pg\_hba.conf} file, and
+just prior the the existing ``local'' and ``host'' lines, add the line:
+
+\footnotesize
+\begin{verbatim}
+ local bacula bacula md5
+\end{verbatim}
+\normalsize
+
+and restart the Postgres database server (frequently, this can be done
+using "/etc/init.d/postgresql restart" or "service postgresql restart") to
+put this new authentication rule into effect.
+
+Next, become the Postgres administrator, postgres, either by logging
+on as the postgres user, or by using su to become root and then using
+su - postgres to become postgres. Add a password to the bacula
+database for the bacula user using:
+
+\footnotesize
+\begin{verbatim}
+ \$ psql bacula
+ bacula=# alter user bacula with password 'secret';
+ ALTER USER
+ bacula=# \\q
+\end{verbatim}
+\normalsize
+
+You'll have to add this password to two locations in the
+bacula-dir.conf file: once to the Catalog resource and once to the
+RunBeforeJob entry in the BackupCatalog Job resource. With the
+password in place, these two lines should look something like:
+
+\footnotesize
+\begin{verbatim}
+ dbname = bacula; user = bacula; password = "secret"
+ ... and ...
+ # WARNING!!! Passing the password via the command line is insecure.
+ # see comments in make_catalog_backup for details.
+ RunBeforeJob = "/etc/make_catalog_backup bacula bacula secret"
+\end{verbatim}
+\normalsize
+
+Naturally, you should choose your own significantly more random
+password, and ensure that the bacula-dir.conf file containing this
+password is readable only by the root.
+
+Even with the files containing the database password properly
+restricted, there is still a security problem with this approach: on
+some platforms, the environment variable that is used to supply the
+password to Postgres is available to all users of the
+local system. To eliminate this problem, the Postgres team have
+deprecated the use of the environment variable password-passing
+mechanism and recommend the use of a .pgpass file instead. To use
+this mechanism, create a file named .pgpass containing the single
+line:
+
+\footnotesize
+\begin{verbatim}
+ localhost:5432:bacula:bacula:secret
+\end{verbatim}
+\normalsize
+
+This file should be copied into the home directory of all accounts
+that will need to gain access to the database: typically, root,
+bacula, and any users who will make use of any of the console
+programs. The files must then have the owner and group set to match
+the user (so root:root for the copy in ~root, and so on), and the mode
+set to 600, limiting access to the owner of the file.
+
+\section{Re-initializing the Catalog Database}
+\index[general]{Database!Re-initializing the Catalog }
+\index[general]{Re-initializing the Catalog Database }
+
+After you have done some initial testing with {\bf Bacula}, you will probably
+want to re-initialize the catalog database and throw away all the test Jobs
+that you ran. To do so, you can do the following:
+
+\footnotesize
+\begin{verbatim}
+ cd <install-directory>
+ ./drop_bacula_tables
+ ./make_bacula_tables
+ ./grant_bacula_privileges
+\end{verbatim}
+\normalsize
+
+Please note that all information in the database will be lost and you will be
+starting from scratch. If you have written on any Volumes, you must write an
+end of file mark on the volume so that Bacula can reuse it. Do so with:
+
+\footnotesize
+\begin{verbatim}
+ (stop Bacula or unmount the drive)
+ mt -f /dev/nst0 rewind
+ mt -f /dev/nst0 weof
+\end{verbatim}
+\normalsize
+
+Where you should replace {\bf /dev/nst0} with the appropriate tape drive

+\section{Installing PostgreSQL from RPMs}
+\index[general]{PostgreSQL!Installing from RPMs}
+\index[general]{Installing PostgreSQL from RPMs}
+If you are installing PostgreSQL from RPMs, you will need to install
+both the PostgreSQL binaries and the client libraries. The client
+libraries are usually found in a devel package, so you must
+install:
+
+\footnotesize
+\begin{verbatim}
+ postgresql
+ postgresql-devel
+ postgresql-server
+ postgresql-libs
+\end{verbatim}
+\normalsize
+
+These will be similar with most other package managers too. After
+installing from rpms, you will still need to run the scripts that set up
+the database and create the tables as described above.
+
+
+\section{Converting from MySQL to PostgreSQL}
+\index[general]{PostgreSQL!Converting from MySQL to }
+\index[general]{Converting from MySQL to PostgreSQL }
+
+The conversion procedure presented here was worked out by Norm Dressler
+\lt{}ndressler at dinmar dot com\gt{}
+
+This process was tested using the following software versions:
+
+\begin{itemize}
+\item Linux Mandrake 10/Kernel 2.4.22-10 SMP
+\item Mysql Ver 12.21 Distrib 4.0.15, for mandrake-linux-gnu (i586)
+\item PostgreSQL 7.3.4
+\item Bacula 1.34.5
+ \end{itemize}
+
+WARNING: Always as a precaution, take a complete backup of your databases
+before proceeding with this process!
+
+\begin{enumerate}
+\item Shutdown bacula (cd /etc/bacula;./bacula stop)
+\item Run the following command to dump your Mysql database:
+
+ \footnotesize
+\begin{verbatim}
+ mysqldump -f -t -n >bacula-backup.dmp
+
+\end{verbatim}
+\normalsize
+
+\item Make a backup of your /etc/bacula directory (but leave the original in
+ place).
+\item Go to your Bacula source directory and rebuild it to include PostgreSQL
+ support rather then Mysql support. Check the config.log file for your
+ original configure command and replace enable-mysql with enable-postgresql.
+\item Recompile Bacula with a make and if everything compiles completely,
+ perform a make install.
+\item Shutdown Mysql.
+\item Start PostgreSQL on your system.
+\item Create a bacula user in Postgres with the createuser command. Depending on
+ your Postgres install, you may have to SU to the user who has privileges to
+ create a user.
+\item Verify your pg\_hba.conf file contains sufficient permissions to allow
+ bacula to access the server. Mine has the following since it's on a secure
+ network:
+
+\footnotesize
+\begin{verbatim}
+local all all trust
+
+host all all 127.0.0.1 255.255.255.255 trust
+
+NOTE: you should restart your postgres server if you
+ made changes
+
+\end{verbatim}
+\normalsize
+
+\item Change into the /etc/bacula directory and prepare the database and
+ tables with the following commands:
+
+\footnotesize
+\begin{verbatim}
+./create_postgresql_database
+
+./make_postgresql_tables
+
+./grant_postgresql_privileges
+
+\end{verbatim}
+\normalsize
+
+\item Verify you have access to the database:
+
+ \footnotesize
+\begin{verbatim}
+
+psql -Ubacula bacula
+
+\end{verbatim}
+\normalsize
+
+You should not get any errors.
+\item Load your database from the Mysql database dump with:
+
+ \footnotesize
+\begin{verbatim}
+psql -Ubacula bacula <bacula-backup.dmp>
+
+\end{verbatim}
+\normalsize
+
+\item Resequence your tables with the following commands:
+
+ \footnotesize
+\begin{verbatim}
+psql -Ubacula bacula
+
+SELECT SETVAL('basefiles_baseid_seq', (SELECT
+MAX(baseid) FROM basefiles));
+SELECT SETVAL('client_clientid_seq', (SELECT
+MAX(clientid) FROM client));
+SELECT SETVAL('file_fileid_seq', (SELECT MAX(fileid)
+FROM file));
+SELECT SETVAL('filename_filenameid_seq', (SELECT
+MAX(filenameid) FROM filename));
+
+SELECT SETVAL('fileset_filesetid_seq', (SELECT
+MAX(filesetid) FROM fileset));
+
+SELECT SETVAL('job_jobid_seq', (SELECT MAX(jobid) FROM job));
+SELECT SETVAL('jobmedia_jobmediaid_seq', (SELECT
+MAX(jobmediaid) FROM jobmedia));
+SELECT SETVAL('media_mediaid_seq', (SELECT MAX(mediaid) FROM media));
+SELECT SETVAL('path_pathid_seq', (SELECT MAX(pathid) FROM path));
+
+SELECT SETVAL('pool_poolid_seq', (SELECT MAX(poolid) FROM pool));
+
+\end{verbatim}
+\normalsize
+
+\item At this point, start up Bacula, verify your volume library and perform
+ a test backup to make sure everything is working properly.
+\end{enumerate}
+
+\section{Upgrading PostgreSQL}
+\index[general]{Upgrading PostgreSQL }
+\index[general]{Upgrading!PostgreSQL }
+\index[general]{Upgrading}
+If you upgrade PostgreSQL, you must reconfigure, rebuild, and re-install
+Bacula otherwise you are likely to get bizarre failures. If you
+to modify the bacula.spec file to account for the new PostgreSQL version.
+You can do so by rebuilding from the source rpm. To do so, you may need
+install from rpms and you upgrade PostgreSQL, you must also rebuild Bacula.
+
+\section{Tuning PostgreSQL}
+\index[general]{Tuning}
+
+If you despool attributes for many jobs at the same time, you can tune the
+sequence object for the \texttt{FileId} field.
+\begin{verbatim}
+psql -Ubacula bacula
+
+ALTER SEQUENCE file_fileid_seq CACHE 1000;
+\end{verbatim}
+
+\section{Credits}
+\index[general]{Credits }
+Many thanks to Dan Langille for writing the PostgreSQL driver. This will
+surely become the most popular database that Bacula supports.

+\chapter{Installing and Configuring SQLite}
+\label{SqlLiteChapter}
+\index[general]{Installing and Configuring SQLite }
+\index[general]{SQLite!Installing and Configuring }
+
+Please note that SQLite both versions 2 and 3 are not network enabled,
+which means that they must be linked into the Director rather than accessed
+by the network as MySQL and PostgreSQL are. This has two consequences:
+\begin{enumerate}
+\item SQLite cannot be used in the {\bf bweb} web GUI package.
+\item If you use SQLite, and your Storage daemon is not on the same
+machine as your Director, you will need to transfer your database
+to the Storage daemon's machine before you can use any of the SD tools
+such as {\bf bscan}, ...
+\end{enumerate}
+
+\section{Installing and Configuring SQLite -- Phase I}
+\index[general]{Phase I!Installing and Configuring SQLite -- }
+\index[general]{Installing and Configuring SQLite -- Phase I }
+
+If you use the {\bf ./configure \verb:--:with-sqlite} statement for configuring {\bf
+Bacula}, you will need SQLite version 2.8.16 or later installed. Our standard
+location (for the moment) for SQLite is in the dependency package {\bf
+depkgs/sqlite-2.8.16}. Please note that the version will be updated as new
+versions are available and tested.
+
+Installing and Configuring is quite easy.
+
+\begin{enumerate}
+\item Download the Bacula dependency packages
+\item Detar it with something like:
+
+ {\bf tar xvfz depkgs.tar.gz}
+
+ Note, the above command requires GNU tar. If you do not have GNU tar, a
+ command such as:
+
+ {\bf zcat depkgs.tar.gz | tar xvf -}
+
+ will probably accomplish the same thing.
+
+\item {\bf cd depkgs}
+
+\item {\bf make sqlite}
+
+\end{enumerate}
+
+
+Please note that the {\bf ./configure} used to build {\bf Bacula} will need to
+include {\bf \verb:--:with-sqlite} or {\bf \verb:--:with-sqlite3} depending
+one which version of SQLite you are using. You should not use the {\bf
+\verb:--:enable-batch-insert} configuration parameter for Bacula if you
+are using SQLite version 2 as it is probably not thread safe. If you
+are using SQLite version 3, you may use the {\bf \verb:--:enable-batch-insert}
+configuration option with Bacula, but when building SQLite3 you MUST
+configure it with {\bf \verb:--:enable-threadsafe} and
+{\bf \verb:--:enable-cross-thread-connections}.
+
+By default, SQLite3 is now run with {\bf PRAGMA synchronous=OFF} this
+increases the speed by more than 30 time, but it also increases the
+possibility of a corrupted database if your server crashes (power failure
+or kernel bug). If you want more security, you can change the PRAGMA
+that is used in the file src/version.h.
+
+
+At this point, you should return to completing the installation of {\bf
+Bacula}.
+
+
+\section{Installing and Configuring SQLite -- Phase II}
+\label{phase2}
+\index[general]{Phase II!Installing and Configuring SQLite -- }
+\index[general]{Installing and Configuring SQLite -- Phase II }
+
+This phase is done {\bf after} you have run the {\bf ./configure} command to
+configure {\bf Bacula}.
+
+{\bf Bacula} will install scripts for manipulating the database (create,
+delete, make tables etc) into the main installation directory. These files
+will be of the form *\_bacula\_* (e.g. create\_bacula\_database). These files
+are also available in the \lt{}bacula-src\gt{}/src/cats directory after
+running ./configure. If you inspect create\_bacula\_database, you will see
+that it calls create\_sqlite\_database. The *\_bacula\_* files are provided
+for convenience. It doesn't matter what database you have chosen;
+create\_bacula\_database will always create your database.
+
+At this point, you can create the SQLite database and tables:
+
+\begin{enumerate}
+\item cd \lt{}install-directory\gt{}
+
+ This directory contains the Bacula catalog interface routines.
+
+\item ./make\_sqlite\_tables
+
+ This script creates the SQLite database as well as the tables used by {\bf
+ Bacula}. This script will be automatically setup by the {\bf ./configure}
+ program to create a database named {\bf bacula.db} in {\bf Bacula's} working
+ directory.
+\end{enumerate}
+
+\section{Linking Bacula with SQLite}
+\index[general]{SQLite!Linking Bacula with }
+\index[general]{Linking Bacula with SQLite }
+
+If you have followed the above steps, this will all happen automatically and
+the SQLite libraries will be linked into {\bf Bacula}.
+
+\section{Testing SQLite}
+\index[general]{SQLite!Testing }
+\index[general]{Testing SQLite }
+
+We have much less "production" experience using SQLite than using MySQL.
+SQLite has performed flawlessly for us in all our testing. However,
+several users have reported corrupted databases while using SQLite. For
+that reason, we do not recommend it for production use.
+
+If Bacula crashes with the following type of error when it is started:
+\footnotesize
+\begin{verbatim}
+Using default Catalog name=MyCatalog DB=bacula
+Could not open database "bacula".
+sqlite.c:151 Unable to open Database=/var/lib/bacula/bacula.db.
+ERR=malformed database schema - unable to open a temporary database file
+for storing temporary tables
+\end{verbatim}
+\normalsize
+
+this is most likely caused by the fact that some versions of
+SQLite attempt to create a temporary file in the current directory.
+If that fails, because Bacula does not have write permission on
+the current directory, then you may get this errr. The solution is
+to start Bacula in a current directory where it has write permission.
+
+
+\section{Re-initializing the Catalog Database}
+\index[general]{Database!Re-initializing the Catalog }
+\index[general]{Re-initializing the Catalog Database }
+
+After you have done some initial testing with {\bf Bacula}, you will probably
+want to re-initialize the catalog database and throw away all the test Jobs
+that you ran. To do so, you can do the following:
+
+\footnotesize
+\begin{verbatim}
+ cd <install-directory>
+ ./drop_sqlite_tables
+ ./make_sqlite_tables
+\end{verbatim}
+\normalsize
+
+Please note that all information in the database will be lost and you will be
+starting from scratch. If you have written on any Volumes, you must write an
+end of file mark on the volume so that Bacula can reuse it. Do so with:
+
+\footnotesize
+\begin{verbatim}
+ (stop Bacula or unmount the drive)
+ mt -f /dev/nst0 rewind
+ mt -f /dev/nst0 weof
+\end{verbatim}
+\normalsize
+
+Where you should replace {\bf /dev/nst0} with the appropriate tape drive
+device name for your machine.

+\chapter{ANSI and IBM Tape Labels}
+\label{AnsiLabelsChapter}
+\index[general]{ANSI and IBM Tape Labels}
+\index[general]{Labels!Tape}
+
+Bacula supports ANSI or IBM tape labels as long as you
+enable it. In fact, with the proper configuration, you can
+force Bacula to require ANSI or IBM labels.
+
+Bacula can create an ANSI or IBM label, but if Check Labels is
+enabled (see below), Bacula will look for an existing label, and
+if it is found, it will keep the label. Consequently, you
+can label the tapes with programs other than Bacula, and Bacula
+will recognize and support them.
+
+Even though Bacula will recognize and write ANSI and IBM labels,
+it always writes its own tape labels as well.
+
+When using ANSI or IBM tape labeling, you must restrict your Volume
+names to a maximum of six characters.
+
+If you have labeled your Volumes outside of Bacula, then the
+ANSI/IBM label will be recognized by Bacula only if you have created
+the HDR1 label with {\bf BACULA.DATA} in the Filename field (starting
+with character 5). If Bacula writes the labels, it will use
+this information to recognize the tape as a Bacula tape. This allows
+ANSI/IBM labeled tapes to be used at sites with multiple machines
+and multiple backup programs.
+
+
+\section{Director Pool Directive}
+
+\begin{description}
+\item [ Label Type = ANSI | IBM | Bacula]
+ This directive is implemented in the Director Pool resource and in the SD Device
+ resource. If it is specified in the SD Device resource, it will take
+ precedence over the value passed from the Director to the SD. The default
+ is Label Type = Bacula.
+\end{description}
+
+\section{Storage Daemon Device Directives}
+
+\begin{description}
+\item [ Label Type = ANSI | IBM | Bacula]
+ This directive is implemented in the Director Pool resource and in the SD Device
+ resource. If it is specified in the the SD Device resource, it will take
+ precedence over the value passed from the Director to the SD.
+
+\item [Check Labels = yes | no]
+ This directive is implemented in the the SD Device resource. If you intend
+ to read ANSI or IBM labels, this *must* be set. Even if the volume is
+ not ANSI labeled, you can set this to yes, and Bacula will check the
+ label type. Without this directive set to yes, Bacula will assume that
+ labels are of Bacula type and will not check for ANSI or IBM labels.
+ In other words, if there is a possibility of Bacula encountering an
+ ANSI/IBM label, you must set this to yes.

+\chapter{Autochanger Resource}
+\index[sd]{Autochanger Resource}
+\index[sd]{Resource!Autochanger}
+
+The Autochanger resource supports single or multiple drive
+autochangers by grouping one or more Device resources
+into one unit called an autochanger in Bacula (often referred to
+as a "tape library" by autochanger manufacturers).
+
+If you have an Autochanger, and you want it to function correctly,
+you {\bf must} have an Autochanger resource in your Storage
+conf file, and your Director's Storage directives that want to
+use an Autochanger {\bf must} refer to the Autochanger resource name.
+In previous versions of Bacula, the Director's Storage directives
+referred directly to Device resources that were autochangers.
+In version 1.38.0 and later, referring directly to Device resources
+will not work for Autochangers.
+
+\begin{description}
+\item [Name = \lt{}Autochanger-Name\gt{}]
+ \index[sd]{Name}
+ Specifies the Name of the Autochanger. This name is used in the
+ Director's Storage definition to refer to the autochanger. This
+ directive is required.
+
+\item [Device = \lt{}Device-name1, device-name2, ...\gt{}]
+ Specifies the names of the Device resource or resources that correspond
+ to the autochanger drive. If you have a multiple drive autochanger, you
+ must specify multiple Device names, each one referring to a separate
+ Device resource that contains a Drive Index specification that
+ corresponds to the drive number base zero. You may specify multiple
+ device names on a single line separated by commas, and/or you may
+ specify multiple Device directives. This directive is required.
+
+\item [Changer Device = {\it name-string}]
+ \index[sd]{Changer Device}
+ The specified {\bf name-string} gives the system file name of the autochanger
+ device name. If specified in this resource, the Changer Device name
+ is not needed in the Device resource. If it is specified in the Device
+ resource (see above), it will take precedence over one specified in
+ the Autochanger resource.
+
+\item [Changer Command = {\it name-string}]
+ \index[sd]{Changer Command }
+ The {\bf name-string} specifies an external program to be called that will
+ automatically change volumes as required by {\bf Bacula}. Most frequently,
+ you will specify the Bacula supplied {\bf mtx-changer} script as follows.
+ If it is specified here, it need not be specified in the Device
+ resource. If it is also specified in the Device resource, it will take
+ precedence over the one specified in the Autochanger resource.
+
+\end{description}
+
+The following is an example of a valid Autochanger resource definition:
+
+\footnotesize
+\begin{verbatim}
+Autochanger {
+ Name = "DDS-4-changer"
+ Device = DDS-4-1, DDS-4-2, DDS-4-3
+ Changer Device = /dev/sg0
+ Changer Command = "/etc/bacula/mtx-changer %c %o %S %a %d"
+}
+Device {
+ Name = "DDS-4-1"
+ Drive Index = 0
+ Autochanger = yes
+ ...
+}
+Device {
+ Name = "DDS-4-2"
+ Drive Index = 1
+ Autochanger = yes
+ ...
+Device {
+ Name = "DDS-4-3"
+ Drive Index = 2
+ Autochanger = yes
+ Autoselect = no
+ ...
+}
+\end{verbatim}
+\normalsize
+
+Please note that it is important to include the {\bf Autochanger = yes} directive
+in each Device definition that belongs to an Autochanger. A device definition
+should not belong to more than one Autochanger resource. Also, your Device
+directive in the Storage resource of the Director's conf file should have
+the Autochanger's resource name rather than a name of one of the Devices.
+
+If you have a drive that physically belongs to an Autochanger but you don't want
+to have it automatically used when Bacula references the Autochanger for backups,
+for example, you want to reserve it for restores, you can add the directive:
+
+\footnotesize
+\begin{verbatim}
+Autoselect = no
+\end{verbatim}
+\normalsize
+
+to the Device resource for that drive. In that case, Bacula will not automatically
+select that drive when accessing the Autochanger. You can, still use the drive
+by referencing it by the Device name directly rather than the Autochanger name. An example
+of such a definition is shown above for the Device DDS-4-3, which will not be
+selected when the name DDS-4-changer is used in a Storage definition, but will
+be used if DDS-4-3 is used.

+\chapter{Autochanger Support}
+\label{AutochangersChapter}
+\index[general]{Support!Autochanger }
+\index[general]{Autochanger Support }
+
+Bacula provides autochanger support for reading and writing tapes. In
+order to work with an autochanger, Bacula requires a number of things, each of
+which is explained in more detail after this list:
+
+\begin{itemize}
+\item A script that actually controls the autochanger according to commands
+ sent by Bacula. We furnish such a script that works with {\bf mtx} found in
+ the {\bf depkgs} distribution.
+
+\item That each Volume (tape) to be used must be defined in the Catalog and
+ have a Slot number assigned to it so that Bacula knows where the Volume is
+ in the autochanger. This is generally done with the {\bf label} command, but
+ can also done after the tape is labeled using the {\bf update slots}
+ command. See below for more details. You must pre-label the tapes manually
+ before using them.
+
+\item Modifications to your Storage daemon's Device configuration resource to
+ identify that the device is a changer, as well as a few other parameters.
+
+\item You should also modify your Storage resource definition in the
+ Director's configuration file so that you are automatically prompted for the
+ Slot when labeling a Volume.
+
+\item You need to ensure that your Storage daemon (if not running as root)
+ has access permissions to both the tape drive and the control device.
+
+\item You need to have {\bf Autochanger = yes} in your Storage resource
+ in your bacula-dir.conf file so that you will be prompted for the
+ slot number when you label Volumes.
+\end{itemize}
+
+In version 1.37 and later, there is a new \ilink{Autochanger
+resource}{AutochangerRes} that permits you to group Device resources thus
+creating a multi-drive autochanger. If you have an autochanger,
+you {\bf must} use this new resource.
+
+Bacula uses its own {\bf mtx-changer} script to interface with a program
+that actually does the tape changing. Thus in principle, {\bf mtx-changer}
+can be adapted to function with any autochanger program, or you can
+call any other script or program. The current
+version of {\bf mtx-changer} works with the {\bf mtx} program. However,
+FreeBSD users have provided a script in the {\bf examples/autochangers}
+directory that allows Bacula to use the {\bf chio} program.
+
+Bacula also supports autochangers with barcode
+readers. This support includes two Console commands: {\bf label barcodes}
+and {\bf update slots}. For more details on these commands, see the "Barcode
+Support" section below.
+
+Current Bacula autochanger support does not include cleaning, stackers, or
+silos. Stackers and silos are not supported because Bacula expects to
+be able to access the Slots randomly.
+However, if you are very careful to setup Bacula to access the Volumes
+in the autochanger sequentially, you may be able to make Bacula
+work with stackers (gravity feed and such).
+
+Support for multi-drive
+autochangers requires the \ilink{Autochanger resource}{AutochangerRes}
+introduced in version 1.37. This resource is also recommended for single
+drive autochangers.
+
+In principle, if {\bf mtx} will operate your changer correctly, then it is
+just a question of adapting the {\bf mtx-changer} script (or selecting one
+already adapted) for proper interfacing. You can find a list of autochangers
+supported by {\bf mtx} at the following link:
+\elink{http://mtx.opensource-sw.net/compatibility.php}
+{http://mtx.opensource-sw.net/compatibility.php}.
+The home page for the {\bf mtx} project can be found at:
+\elink{http://mtx.opensource-sw.net/}{http://mtx.opensource-sw.net/}.
+
+Note, we have feedback from some users that there are certain
+incompatibilities between the Linux kernel and mtx. For example between
+kernel 2.6.18-8.1.8.el5 of CentOS and RedHat and version 1.3.10 and 1.3.11
+of mtx. This was fixed by upgrading to a version 2.6.22 kernel.
+
+In addition, apparently certain versions of mtx, for example, version
+1.3.11 limit the number of slots to a maximum of 64. The solution was to
+use version 1.3.10.
+
+If you are having troubles, please use the {\bf auto} command in the {\bf
+btape} program to test the functioning of your autochanger with Bacula. When
+Bacula is running, please remember that for many distributions (e.g. FreeBSD,
+Debian, ...) the Storage daemon runs as {\bf bacula.tape} rather than {\bf
+root.root}, so you will need to ensure that the Storage daemon has sufficient
+permissions to access the autochanger.
+
+Some users have reported that the the Storage daemon blocks under certain
+circumstances in trying to mount a volume on a drive that has a different
+volume loaded. As best we can determine, this is simply a matter of
+waiting a bit. The drive was previously in use writing a Volume, and
+sometimes the drive will remain BLOCKED for a good deal of time (up to 7
+minutes on a slow drive) waiting for the cassette to rewind and to unload
+before the drive can be used with a different Volume.

+\end{verbatim}
+\normalsize
+
+For more detailed information on what SCSI devices you have please see
+the \ilink{Linux SCSI Tricks}{SCSITricks} section of the Tape Testing
+chapter of this manual.
+
+Under FreeBSD, you can use:
+
+\footnotesize
+\begin{verbatim}
+camcontrol devlist
+\end{verbatim}
+\normalsize
+
+To list the SCSI devices as well as the {\bf /dev/passn} that you will use on
+the Bacula {\bf Changer Device = } directive.
+
+Please check that your Storage daemon has permission to access this
+device.
+
+The following tip for FreeBSD users comes from Danny Butroyd:
+on reboot Bacula will NOT have permission to
+control the device /dev/pass0 (assuming this is your changer device).
+To get around this just edit the /etc/devfs.conf file and add the
+following to the bottom:
+\footnotesize
+\begin{verbatim}
+own pass0 root:bacula
+perm pass0 0666
+own nsa0.0 root:bacula
+perm nsa0.0 0666
+\end{verbatim}
+\normalsize
+
+This gives the bacula group permission to write to the nsa0.0 device
+too just to be on the safe side. To bring these changes into effect
+just run:-
+
+/etc/rc.d/devfs restart
+
+Basically this will stop you having to manually change permissions on these
+devices to make Bacula work when operating the AutoChanger after a reboot.
+
+\label{scripts}
+\section{Example Scripts}
+\index[general]{Scripts!Example }
+\index[general]{Example Scripts }
+
+Please read the sections below so that you understand how autochangers work
+with Bacula. Although we supply a default {\bf mtx-changer} script, your
+autochanger may require some additional changes. If you want to see examples
+of configuration files and scripts, please look in the {\bf
+\lt{}bacula-src\gt{}/examples/devices} directory where you will find an
+example {\bf HP-autoloader.conf} Bacula Device resource, and several {\bf
+mtx-changer} scripts that have been modified to work with different
+autochangers.
+
+\label{Slots}
+
+\section{Slots}
+\index[general]{Slots }
+
+To properly address autochangers, Bacula must know which Volume is in each
+{\bf slot} of the autochanger. Slots are where the changer cartridges reside
+when not loaded into the drive. Bacula numbers these slots from one to the
+number of cartridges contained in the autochanger.
+
+Bacula will not automatically use a Volume in your autochanger unless it is
+labeled and the slot number is stored in the catalog and the Volume is marked
+as InChanger. This is because it must know where each volume is (slot) to
+be able to load the volume.
+For each Volume in your
+changer, you will, using the Console program, assign a slot. This information
+is kept in {\bf Bacula's} catalog database along with the other data for the
+volume. If no slot is given, or the slot is set to zero, Bacula will not
+attempt to use the autochanger even if all the necessary configuration records
+are present. When doing a {\bf mount} command on an autochanger, you must
+specify which slot you want mounted. If the drive is loaded with a tape
+from another slot, it will unload it and load the correct tape, but
+normally, no tape will be loaded because an {\bf unmount} command causes
+Bacula to unload the tape in the drive.
+
+
+You can check if the Slot number and InChanger flag are set by doing a:
+\begin{verbatim}
+list Volumes
+\end{verbatim}
+
+in the Console program.
+
+\label{mult}
+\section{Multiple Devices}
+\index[general]{Devices!Multiple}
+\index[general]{Multiple Devices}
+
+Some autochangers have more than one read/write device (drive). The
+new \ilink{Autochanger resource}{AutochangerRes} introduced in version
+1.37 permits you to group Device resources, where each device
+represents a drive. The Director may still reference the Devices (drives)
+directly, but doing so, bypasses the proper functioning of the
+drives together. Instead, the Director (in the Storage resource)
+should reference the Autochanger resource name. Doing so permits
+the Storage daemon to ensure that only one drive uses the mtx-changer
+script at a time, and also that two drives don't reference the
+same Volume.
+
+Multi-drive requires the use of the {\bf
+Drive Index} directive in the Device resource of the Storage daemon's
+configuration file. Drive numbers or the Device Index are numbered beginning
+at zero, which is the default. To use the second Drive in an autochanger, you
+need to define a second Device resource and set the Drive Index to 1 for
+that device. In general, the second device will have the same {\bf Changer
+Device} (control channel) as the first drive, but a different {\bf Archive
+Device}.
+
+As a default, Bacula jobs will prefer to write to a Volume that is
+already mounted. If you have a multiple drive autochanger and you want
+Bacula to write to more than one Volume in the same Pool at the same
+time, you will need to set \ilink{Prefer Mounted Volumes} {PreferMountedVolumes}
+in the Directors Job resource to {\bf no}. This will cause
+the Storage daemon to maximize the use of drives.
+
+
+\label{ConfigRecords}
+\section{Device Configuration Records}
+\index[general]{Records!Device Configuration }
+\index[general]{Device Configuration Records }
+
+Configuration of autochangers within Bacula is done in the Device resource of
+the Storage daemon. Four records: {\bf Autochanger}, {\bf Changer Device},
+{\bf Changer Command}, and {\bf Maximum Changer Wait} control how Bacula uses
+the autochanger.
+
+These four records, permitted in {\bf Device} resources, are described in
+detail below. Note, however, that the {\bf Changer Device} and the
+{\bf Changer Command} directives are not needed in the Device resource
+if they are present in the {\bf Autochanger} resource.
+
+\begin{description}
+
+\item [Autochanger = {\it Yes|No} ]
+ \index[sd]{Autochanger }
+ The {\bf Autochanger} record specifies that the current device is or is not
+an autochanger. The default is {\bf no}.
+
+\item [Changer Device = \lt{}device-name\gt{}]
+ \index[sd]{Changer Device }
+ In addition to the Archive Device name, you must specify a {\bf Changer
+Device} name. This is because most autochangers are controlled through a
+different device than is used for reading and writing the cartridges. For
+example, on Linux, one normally uses the generic SCSI interface for
+controlling the autochanger, but the standard SCSI interface for reading and
+writing the tapes. On Linux, for the {\bf Archive Device = /dev/nst0}, you
+would typically have {\bf Changer Device = /dev/sg0}. Note, some of the more
+advanced autochangers will locate the changer device on {\bf /dev/sg1}. Such
+devices typically have several drives and a large number of tapes.
+
+On FreeBSD systems, the changer device will typically be on {\bf /dev/pass0}
+through {\bf /dev/passn}.
+
+On Solaris, the changer device will typically be some file under {\bf
+/dev/rdsk}.
+
+Please ensure that your Storage daemon has permission to access this
+device.
+
+\item [Changer Command = \lt{}command\gt{}]
+ \index[sd]{Changer Command }
+ This record is used to specify the external program to call and what
+arguments to pass to it. The command is assumed to be a standard program or
+shell script that can be executed by the operating system. This command is
+invoked each time that Bacula wishes to manipulate the autochanger. The
+following substitutions are made in the {\bf command} before it is sent to
+the operating system for execution:
+
+\footnotesize
+\begin{verbatim}
+ %% = %
+ %a = archive device name
+ %c = changer device name
+ %d = changer drive index base 0
+ %f = Client's name
+ %j = Job name
+ %o = command (loaded, load, or unload)
+ %s = Slot base 0
+ %S = Slot base 1
+ %v = Volume name
+\end{verbatim}
+\normalsize
+
+An actual example for using {\bf mtx} with the {\bf mtx-changer} script (part
+of the Bacula distribution) is:
+
+\footnotesize
+\begin{verbatim}
+Changer Command = "/etc/bacula/mtx-changer %c %o %S %a %d"
+\end{verbatim}
+\normalsize
+
+Where you will need to adapt the {\bf /etc/bacula} to be the actual path on
+your system where the mtx-changer script resides. Details of the three
+commands currently used by Bacula (loaded, load, unload) as well as the
+output expected by Bacula are give in the {\bf Bacula Autochanger Interface}
+section below.
+
+\item [Maximum Changer Wait = \lt{}time\gt{}]
+ \index[sd]{Maximum Changer Wait }
+ This record is used to define the maximum amount of time that Bacula
+ will wait for an autoloader to respond to a command (e.g. load). The
+ default is set to 120 seconds. If you have a slow autoloader you may
+ want to set it longer.
+
+If the autoloader program fails to respond in this time, it will be killed
+and Bacula will request operator intervention.
+
+\item [Drive Index = \lt{}number\gt{}]
+ \index[sd]{Drive Index }
+ This record allows you to tell Bacula to use the second or subsequent
+ drive in an autochanger with multiple drives. Since the drives are
+ numbered from zero, the second drive is defined by
+
+\footnotesize
+\begin{verbatim}
+Device Index = 1
+
+\end{verbatim}
+\normalsize
+
+To use the second drive, you need a second Device resource definition in the
+Bacula configuration file. See the Multiple Drive section above in this
+chapter for more information.
+\end{description}
+
+In addition, for proper functioning of the Autochanger, you must
+define an Autochanger resource.

+\label{SpecifyingSlots}
+\section{Specifying Slots When Labeling}
+\index[general]{Specifying Slots When Labeling }
+\index[general]{Labeling!Specifying Slots When }
+
+If you add an {\bf Autochanger = yes} record to the Storage resource in your
+Director's configuration file, the Bacula Console will automatically prompt
+you for the slot number when the Volume is in the changer when
+you {\bf add} or {\bf label} tapes for that Storage device. If your
+{\bf mtx-changer} script is properly installed, Bacula will automatically
+load the correct tape during the label command.
+
+You must also set
+{\bf Autochanger = yes} in the Storage daemon's Device resource
+as we have described above in
+order for the autochanger to be used. Please see the
+\ilink{Storage Resource}{Autochanger1} in the Director's chapter
+and the
+\ilink{Device Resource}{Autochanger} in the Storage daemon
+chapter for more details on these records.
+
+Thus all stages of dealing with tapes can be totally automated. It is also
+possible to set or change the Slot using the {\bf update} command in the
+Console and selecting {\bf Volume Parameters} to update.
+
+Even though all the above configuration statements are specified and correct,
+Bacula will attempt to access the autochanger only if a {\bf slot} is non-zero
+in the catalog Volume record (with the Volume name).
+
+If your autochanger has barcode labels, you can label all the Volumes in
+your autochanger one after another by using the {\bf label barcodes} command.
+For each tape in the changer containing a barcode, Bacula will mount the tape
+and then label it with the same name as the barcode. An appropriate Media
+record will also be created in the catalog. Any barcode that begins with the
+same characters as specified on the "CleaningPrefix=xxx" command, will be
+treated as a cleaning tape, and will not be labeled. For example with:
+
+Please note that Volumes must be pre-labeled to be automatically used in
+the autochanger during a backup. If you do not have a barcode reader, this
+is done manually (or via a script).
+
+\footnotesize
+\begin{verbatim}
+Pool {
+ Name ...
+ Cleaning Prefix = "CLN"
+}
+\end{verbatim}
+\normalsize
+
+Any slot containing a barcode of CLNxxxx will be treated as a cleaning tape
+and will not be mounted.
+
+\section{Changing Cartridges}
+\index[general]{Changing Cartridges }
+If you wish to insert or remove cartridges in your autochanger or
+you manually run the {\bf mtx} program, you must first tell Bacula
+to release the autochanger by doing:
+
+\footnotesize
+\begin{verbatim}
+unmount
+(change cartridges and/or run mtx)
+mount
+\end{verbatim}
+\normalsize
+
+If you do not do the unmount before making such a change, Bacula
+will become completely confused about what is in the autochanger
+and may stop function because it expects to have exclusive use
+of the autochanger while it has the drive mounted.
+
+
+\label{Magazines}
+\section{Dealing with Multiple Magazines}
+\index[general]{Dealing with Multiple Magazines }
+\index[general]{Magazines!Dealing with Multiple }
+
+If you have several magazines or if you insert or remove cartridges from a
+magazine, you should notify Bacula of this. By doing so, Bacula will as
+a preference, use Volumes that it knows to be in the autochanger before
+accessing Volumes that are not in the autochanger. This prevents unneeded
+operator intervention.
+
+If your autochanger has barcodes (machine readable tape labels), the task of
+informing Bacula is simple. Every time, you change a magazine, or add or
+remove a cartridge from the magazine, simply do
+
+\footnotesize
+\begin{verbatim}
+unmount
+(remove magazine)
+(insert new magazine)
+update slots
+mount
+\end{verbatim}
+\normalsize
+
+in the Console program. This will cause Bacula to request the autochanger to
+return the current Volume names in the magazine. This will be done without
+actually accessing or reading the Volumes because the barcode reader does this
+during inventory when the autochanger is first turned on. Bacula will ensure
+that any Volumes that are currently marked as being in the magazine are marked
+as no longer in the magazine, and the new list of Volumes will be marked as
+being in the magazine. In addition, the Slot numbers of the Volumes will be
+corrected in Bacula's catalog if they are incorrect (added or moved).
+
+If you do not have a barcode reader on your autochanger, you have several
+alternatives.
+
+\begin{enumerate}
+\item You can manually set the Slot and InChanger flag using the {\bf update
+ volume} command in the Console (quite painful).
+
+\item You can issue a
+
+\footnotesize
+\begin{verbatim}
+update slots scan
+\end{verbatim}
+\normalsize
+
+ command that will cause Bacula to read the label on each of the cartridges in
+ the magazine in turn and update the information (Slot, InChanger flag) in the
+ catalog. This is quite effective but does take time to load each cartridge
+ into the drive in turn and read the Volume label.
+
+\item You can modify the mtx-changer script so that it simulates an
+ autochanger with barcodes. See below for more details.
+\end{enumerate}
+
+\label{simulating}
+\section{Simulating Barcodes in your Autochanger}
+\index[general]{Autochanger!Simulating Barcodes in your }
+\index[general]{Simulating Barcodes in your Autochanger }
+
+You can simulate barcodes in your autochanger by making the {\bf mtx-changer}
+script return the same information that an autochanger with barcodes would do.
+This is done by commenting out the one and only line in the {\bf list)} case,
+which is:
+
+\footnotesize
+\begin{verbatim}
+ ${MTX} -f $ctl status | grep " *Storage Element [0-9]*:.*Full" | awk "{print \$3 \$4}" | sed "s/Full *\(:VolumeTag=\)*//"
+\end{verbatim}
+\normalsize
+
+at approximately line 99 by putting a \# in column one of that line, or by
+simply deleting it. Then in its place add a new line that prints the contents
+of a file. For example:
+
+\footnotesize
+\begin{verbatim}
+cat /etc/bacula/changer.volumes
+\end{verbatim}
+\normalsize
+
+Be sure to include a full path to the file, which can have any name. The
+contents of the file must be of the following format:
+
+\footnotesize
+\begin{verbatim}
+1:Volume1
+2:Volume2
+3:Volume3
+...
+\end{verbatim}
+\normalsize
+
+Where the 1, 2, 3 are the slot numbers and Volume1, Volume2, ... are the
+Volume names in those slots. You can have multiple files that represent the
+Volumes in different magazines, and when you change magazines, simply copy the
+contents of the correct file into your {\bf /etc/bacula/changer.volumes} file.
+There is no need to stop and start Bacula when you change magazines, simply
+put the correct data in the file, then run the {\bf update slots} command, and
+your autochanger will appear to Bacula to be an autochanger with barcodes.
+\label{updateslots}
+
+\section{The Full Form of the Update Slots Command}
+\index[general]{Full Form of the Update Slots Command }
+\index[general]{Command!Full Form of the Update Slots }
+
+If you change only one cartridge in the magazine, you may not want to scan all
+Volumes, so the {\bf update slots} command (as well as the {\bf update slots
+scan} command) has the additional form:
+
+\footnotesize
+\begin{verbatim}
+update slots=n1,n2,n3-n4, ...
+\end{verbatim}
+\normalsize
+
+where the keyword {\bf scan} can be appended or not. The n1,n2, ... represent
+Slot numbers to be updated and the form n3-n4 represents a range of Slot
+numbers to be updated (e.g. 4-7 will update Slots 4,5,6, and 7).
+
+This form is particularly useful if you want to do a scan (time expensive) and
+restrict the update to one or two slots.
+
+For example, the command:
+
+\footnotesize
+\begin{verbatim}
+update slots=1,6 scan
+\end{verbatim}
+\normalsize
+
+will cause Bacula to load the Volume in Slot 1, read its Volume label and
+update the Catalog. It will do the same for the Volume in Slot 6. The command:
+
+
+\footnotesize
+\begin{verbatim}
+update slots=1-3,6
+\end{verbatim}
+\normalsize
+
+will read the barcoded Volume names for slots 1,2,3 and 6 and make the
+appropriate updates in the Catalog. If you don't have a barcode reader or have
+not modified the mtx-changer script as described above, the above command will
+not find any Volume names so will do nothing.

+\section{FreeBSD Issues}
+\index[general]{Issues!FreeBSD }
+\index[general]{FreeBSD Issues }
+
+If you are having problems on FreeBSD when Bacula tries to select a tape, and
+the message is {\bf Device not configured}, this is because FreeBSD has made
+the tape device {\bf /dev/nsa1} disappear when there is no tape mounted in the
+autochanger slot. As a consequence, Bacula is unable to open the device. The
+solution to the problem is to make sure that some tape is loaded into the tape
+drive before starting Bacula. This problem is corrected in Bacula versions
+1.32f-5 and later.
+
+Please see the
+\ilink{ Tape Testing}{FreeBSDTapes} chapter of this manual for
+{\bf important} information concerning your tape drive before doing the
+autochanger testing.

+\section{Testing Autochanger and Adapting mtx-changer script}
+\index[general]{Testing the Autochanger }
+\index[general]{Adapting Your mtx-changer script}
+
+
+Before attempting to use the autochanger with Bacula, it is preferable to
+"hand-test" that the changer works. To do so, we suggest you do the
+following commands (assuming that the {\bf mtx-changer} script is installed in
+{\bf /etc/bacula/mtx-changer}):
+
+\begin{description}
+
+\item [Make sure Bacula is not running.]
+
+\item [/etc/bacula/mtx-changer \ /dev/sg0 \ list \ 0 \ /dev/nst0 \ 0]
+\index[sd]{mtx-changer list}
+
+This command should print:
+
+\footnotesize
+\begin{verbatim}
+ 1:
+ 2:
+ 3:
+ ...
+
+\end{verbatim}
+\normalsize
+
+or one number per line for each slot that is occupied in your changer, and
+the number should be terminated by a colon ({\bf :}). If your changer has
+barcodes, the barcode will follow the colon. If an error message is printed,
+you must resolve the problem (e.g. try a different SCSI control device name
+if {\bf /dev/sg0} is incorrect). For example, on FreeBSD systems, the
+autochanger SCSI control device is generally {\bf /dev/pass2}.
+
+\item [/etc/bacula/mtx-changer \ /dev/sg0 \ slots ]
+\index[sd]{mtx-changer slots}
+
+This command should return the number of slots in your autochanger.
+
+\item [/etc/bacula/mtx-changer \ /dev/sg0 \ unload \ 1 \ /dev/nst0 \ 0 ]
+\index[sd]{mtx-changer unload}
+
+ If a tape is loaded from slot 1, this should cause it to be unloaded.
+
+\item [/etc/bacula/mtx-changer \ /dev/sg0 \ load \ 3 \ /dev/nst0 \ 0 ]
+\index[sd]{mtx-changer load}
+
+Assuming you have a tape in slot 3, it will be loaded into drive (0).
+
+
+\item [/etc/bacula/mtx-changer \ /dev/sg0 \ loaded \ 0 \ /dev/nst0 \ 0]
+\index[sd]{mtx-changer loaded}
+
+It should print "3"
+Note, we have used an "illegal" slot number 0. In this case, it is simply
+ignored because the slot number is not used. However, it must be specified
+because the drive parameter at the end of the command is needed to select
+the correct drive.
+
+\item [/etc/bacula/mtx-changer \ /dev/sg0 \ unload \ 3 /dev/nst0 \ 0]
+
+will unload the tape into slot 3.
+
+\end{description}
+
+Once all the above commands work correctly, assuming that you have the right
+{\bf Changer Command} in your configuration, Bacula should be able to operate
+the changer. The only remaining area of problems will be if your autoloader
+needs some time to get the tape loaded after issuing the command. After the
+{\bf mtx-changer} script returns, Bacula will immediately rewind and read the
+tape. If Bacula gets rewind I/O errors after a tape change, you will probably
+need to insert a {\bf sleep 20} after the {\bf mtx} command, but be careful to
+exit the script with a zero status by adding {\bf exit 0} after any additional
+commands you add to the script. This is because Bacula checks the return
+status of the script, which should be zero if all went well.
+
+You can test whether or not you need a {\bf sleep} by putting the following
+commands into a file and running it as a script:
+
+\footnotesize
+\begin{verbatim}
+#!/bin/sh
+/etc/bacula/mtx-changer /dev/sg0 unload 1 /dev/nst0 0
+/etc/bacula/mtx-changer /dev/sg0 load 3 /dev/nst0 0
+mt -f /dev/st0 rewind
+mt -f /dev/st0 weof
+\end{verbatim}
+\normalsize
+
+If the above script runs, you probably have no timing problems. If it does not
+run, start by putting a {\bf sleep 30} or possibly a {\bf sleep 60} in the
+script just after the mtx-changer load command. If that works, then you should
+move the sleep into the actual {\bf mtx-changer} script so that it will be
+effective when Bacula runs.
+
+A second problem that comes up with a small number of autochangers is that
+they need to have the cartridge ejected before it can be removed. If this is
+the case, the {\bf load 3} will never succeed regardless of how long you wait.
+If this seems to be your problem, you can insert an eject just after the
+unload so that the script looks like:
+
+\footnotesize
+\begin{verbatim}
+#!/bin/sh
+/etc/bacula/mtx-changer /dev/sg0 unload 1 /dev/nst0 0
+mt -f /dev/st0 offline
+/etc/bacula/mtx-changer /dev/sg0 load 3 /dev/nst0 0
+mt -f /dev/st0 rewind
+mt -f /dev/st0 weof
+\end{verbatim}
+\normalsize
+
+Obviously, if you need the {\bf offline} command, you should move it into the
+mtx-changer script ensuring that you save the status of the {\bf mtx} command
+or always force an {\bf exit 0} from the script, because Bacula checks the
+return status of the script.
+
+As noted earlier, there are several scripts in {\bf
+\lt{}bacula-source\gt{}/examples/devices} that implement the above features,
+so they may be a help to you in getting your script to work.
+
+If Bacula complains "Rewind error on /dev/nst0. ERR=Input/output error." you
+most likely need more sleep time in your {\bf mtx-changer} before returning to
+Bacula after a load command has been completed.
+
+\label{using}

+\section{Using the Autochanger}
+\index[general]{Using the Autochanger }
+\index[general]{Autochanger!Using the }
+
+Let's assume that you have properly defined the necessary Storage daemon
+Device records, and you have added the {\bf Autochanger = yes} record to the
+Storage resource in your Director's configuration file.
+
+Now you fill your autochanger with say six blank tapes.
+
+What do you do to make Bacula access those tapes?
+
+One strategy is to prelabel each of the tapes. Do so by starting Bacula, then
+with the Console program, enter the {\bf label} command:
+
+\footnotesize
+\begin{verbatim}
+./bconsole
+Connecting to Director rufus:8101
+1000 OK: rufus-dir Version: 1.26 (4 October 2002)
+*label
+\end{verbatim}
+\normalsize
+
+it will then print something like:
+
+\footnotesize
+\begin{verbatim}
+Using default Catalog name=BackupDB DB=bacula
+The defined Storage resources are:
+ 1: Autochanger
+ 2: File
+Select Storage resource (1-2): 1
+\end{verbatim}
+\normalsize
+
+I select the autochanger (1), and it prints:
+
+\footnotesize
+\begin{verbatim}
+Enter new Volume name: TestVolume1
+Enter slot (0 for none): 1
+\end{verbatim}
+\normalsize
+
+where I entered {\bf TestVolume1} for the tape name, and slot {\bf 1} for the
+slot. It then asks:
+
+\footnotesize
+\begin{verbatim}
+Defined Pools:
+ 1: Default
+ 2: File
+Select the Pool (1-2): 1
+\end{verbatim}
+\normalsize
+
+I select the Default pool. This will be automatically done if you only have a
+single pool, then Bacula will proceed to unload any loaded volume, load the
+volume in slot 1 and label it. In this example, nothing was in the drive, so
+it printed:
+
+\footnotesize
+\begin{verbatim}
+Connecting to Storage daemon Autochanger at localhost:9103 ...
+Sending label command ...
+3903 Issuing autochanger "load slot 1" command.
+3000 OK label. Volume=TestVolume1 Device=/dev/nst0
+Media record for Volume=TestVolume1 successfully created.
+Requesting mount Autochanger ...
+3001 Device /dev/nst0 is mounted with Volume TestVolume1
+You have messages.
+*
+\end{verbatim}
+\normalsize
+
+You may then proceed to label the other volumes. The messages will change
+slightly because Bacula will unload the volume (just labeled TestVolume1)
+before loading the next volume to be labeled.
+
+Once all your Volumes are labeled, Bacula will automatically load them as they
+are needed.
+
+To "see" how you have labeled your Volumes, simply enter the {\bf list
+volumes} command from the Console program, which should print something like
+the following:
+
+\footnotesize
+\begin{verbatim}
+*{\bf list volumes}

+\label{Barcodes}
+
+\section{Barcode Support}
+\index[general]{Support!Barcode }
+\index[general]{Barcode Support }
+
+Bacula provides barcode support with two Console commands, {\bf label
+barcodes} and {\bf update slots}.
+
+The {\bf label barcodes} will cause Bacula to read the barcodes of all the
+cassettes that are currently installed in the magazine (cassette holder) using
+the {\bf mtx-changer} {\bf list} command. Each cassette is mounted in turn and
+labeled with the same Volume name as the barcode.
+
+The {\bf update slots} command will first obtain the list of cassettes and
+their barcodes from {\bf mtx-changer}. Then it will find each volume in turn
+in the catalog database corresponding to the barcodes and set its Slot to
+correspond to the value just read. If the Volume is not in the catalog, then
+nothing will be done. This command is useful for synchronizing Bacula with the
+current magazine in case you have changed magazines or in case you have moved
+cassettes from one slot to another. If the autochanger is empty, nothing will
+be done.
+
+The {\bf Cleaning Prefix} statement can be used in the Pool resource to define
+a Volume name prefix, which if it matches that of the Volume (barcode) will
+cause that Volume to be marked with a VolStatus of {\bf Cleaning}. This will
+prevent Bacula from attempting to write on the Volume.
+
+\section{Use bconsole to display Autochanger content}
+

+\section{Bacula Autochanger Interface}
+\index[general]{Interface!Bacula Autochanger }
+\index[general]{Bacula Autochanger Interface }
+
+Bacula calls the autochanger script that you specify on the {\bf Changer
+Command} statement. Normally this script will be the {\bf mtx-changer} script
+that we provide, but it can in fact be any program. The only requirement
+for the script is that it must understand the commands that
+Bacula uses, which are {\bf loaded}, {\bf load}, {\bf
+unload}, {\bf list}, and {\bf slots}. In addition,
+each of those commands must return the information in the precise format as
+specified below:
+
+\footnotesize
+\begin{verbatim}
+- Currently the changer commands used are:
+ loaded -- returns number of the slot that is loaded, base 1,
+ in the drive or 0 if the drive is empty.
+ load -- loads a specified slot (note, some autochangers
+ require a 30 second pause after this command) into
+ the drive.
+ unload -- unloads the device (returns cassette to its slot).
+ list -- returns one line for each cassette in the autochanger
+ in the format <slot>:<barcode>. Where
+ the {\bf slot} is the non-zero integer representing
+ the slot number, and {\bf barcode} is the barcode
+ associated with the cassette if it exists and if you
+ autoloader supports barcodes. Otherwise the barcode
+ field is blank.

+\chapter{The Bootstrap File}
+\label{BootstrapChapter}
+\index[general]{File!Bootstrap }
+\index[general]{Bootstrap File }
+
+The information in this chapter is provided so that you may either create your
+own bootstrap files, or so that you can edit a bootstrap file produced by {\bf
+Bacula}. However, normally the bootstrap file will be automatically created
+for you during the
+\ilink{restore\_command}{_ConsoleChapter} command in the Console program, or
+by using a
+\ilink{ Write Bootstrap}{writebootstrap} record in your Backup
+Jobs, and thus you will never need to know the details of this file.
+
+The {\bf bootstrap} file contains ASCII information that permits precise
+specification of what files should be restored, what volume they are on,
+and where they are on the volume. It is a relatively compact
+form of specifying the information, is human readable, and can be edited with
+any text editor.
+
+\section{Bootstrap File Format}
+\index[general]{Format!Bootstrap}
+\index[general]{Bootstrap File Format }
+
+The general format of a {\bf bootstrap} file is:
+
+{\bf \lt{}keyword\gt{}= \lt{}value\gt{}}
+
+Where each {\bf keyword} and the {\bf value} specify which files to restore.
+More precisely the {\bf keyword} and their {\bf values} serve to limit which
+files will be restored and thus act as a filter. The absence of a keyword
+means that all records will be accepted.
+
+Blank lines and lines beginning with a pound sign (\#) in the bootstrap file
+are ignored.
+
+There are keywords which permit filtering by Volume, Client, Job, FileIndex,
+Session Id, Session Time, ...
+
+The more keywords that are specified, the more selective the specification of
+which files to restore will be. In fact, each keyword is {\bf AND}ed with
+other keywords that may be present.
+
+For example,
+
+\footnotesize
+\begin{verbatim}
+Volume = Test-001
+VolSessionId = 1
+VolSessionTime = 108927638
+\end{verbatim}
+\normalsize
+
+directs the Storage daemon (or the {\bf bextract} program) to restore only
+those files on Volume Test-001 {\bf AND} having VolumeSessionId equal to one
+{\bf AND} having VolumeSession time equal to 108927638.
+
+The full set of permitted keywords presented in the order in which they are
+matched against the Volume records are:
+
+\begin{description}
+
+\item [Volume]
+ \index[general]{Volume }
+ The value field specifies what Volume the following commands apply to.
+ Each Volume specification becomes the current Volume, to which all the
+ following commands apply until a new current Volume (if any) is
+ specified. If the Volume name contains spaces, it should be enclosed in
+ quotes. At lease one Volume specification is required.
+
+\item [Count]
+ \index[general]{Count}
+ The value is the total number of files that will be restored for this Volume.
+ This allows the Storage daemon to know when to stop reading the Volume.
+ This value is optional.
+
+\item [VolFile]
+ \index[general]{VolFile}
+ The value is a file number, a list of file numbers, or a range of file
+ numbers to match on the current Volume. The file number represents the
+ physical file on the Volume where the data is stored. For a tape
+ volume, this record is used to position to the correct starting file,
+ and once the tape is past the last specified file, reading will stop.
+
+\item [VolBlock]
+ \index[general]{VolBlock}
+ The value is a block number, a list of block numbers, or a range of
+ block numbers to match on the current Volume. The block number
+ represents the physical block within the file on the Volume where the
+ data is stored.
+
+
+\item [VolSessionTime]
+ \index[general]{VolSessionTime }
+ The value specifies a Volume Session Time to be matched from the current
+ volume.
+
+\item [VolSessionId]
+ \index[general]{VolSessionId }
+ The value specifies a VolSessionId, a list of volume session ids, or a
+ range of volume session ids to be matched from the current Volume. Each
+ VolSessionId and VolSessionTime pair corresponds to a unique Job that is
+ backed up on the Volume.
+
+\item [JobId]
+ \index[general]{JobId }
+ The value specifies a JobId, list of JobIds, or range of JobIds to be
+ selected from the current Volume. Note, the JobId may not be unique if you
+ have multiple Directors, or if you have reinitialized your database. The
+ JobId filter works only if you do not run multiple simultaneous jobs.
+ This value is optional and not used by Bacula to restore files.
+
+\item [Job]
+ \index[general]{Job }
+ The value specifies a Job name or list of Job names to be matched on the
+ current Volume. The Job corresponds to a unique VolSessionId and
+ VolSessionTime pair. However, the Job is perhaps a bit more readable by
+ humans. Standard regular expressions (wildcards) may be used to match Job
+ names. The Job filter works only if you do not run multiple simultaneous
+ jobs.
+ This value is optional and not used by Bacula to restore files.
+
+\item [Client]
+ \index[general]{Client }
+ The value specifies a Client name or list of Clients to will be matched on
+ the current Volume. Standard regular expressions (wildcards) may be used to
+ match Client names. The Client filter works only if you do not run multiple
+ simultaneous jobs.
+ This value is optional and not used by Bacula to restore files.
+
+\item [FileIndex]
+ \index[general]{FileIndex}
+ The value specifies a FileIndex, list of FileIndexes, or range of FileIndexes
+ to be selected from the current Volume. Each file (data) stored on a Volume
+ within a Session has a unique FileIndex. For each Session, the first file
+ written is assigned FileIndex equal to one and incremented for each file
+ backed up.
+
+ This for a given Volume, the triple VolSessionId, VolSessionTime, and
+ FileIndex uniquely identifies a file stored on the Volume. Multiple copies of
+ the same file may be stored on the same Volume, but for each file, the triple
+ VolSessionId, VolSessionTime, and FileIndex will be unique. This triple is
+ stored in the Catalog database for each file.
+
+ To restore a particular file, this value (or a range of FileIndexes) is
+ required.
+
+\item [FileRegex]
+ \index[general]{FileRegex}
+ The value is a regular expression. When specified, only matching
+ filenames will be restored.
+
+\begin{verbatim}
+ FileRegex=^/etc/passwd(.old)?
+\end{verbatim}
+
+\item [Slot]
+ \index[general]{Slot }
+ The value specifies the autochanger slot. There may be only a single {\bf
+ Slot} specification for each Volume.
+
+\item [Stream]
+ \index[general]{Stream }
+ The value specifies a Stream, a list of Streams, or a range of Streams to be
+ selected from the current Volume. Unless you really know what you are doing
+ (the internals of {\bf Bacula}), you should avoid this specification.
+ This value is optional and not used by Bacula to restore files.
+
+\item [*JobType]
+ \index[general]{*JobType }
+ Not yet implemented.
+
+\item [*JobLevel]
+ \index[general]{*JobLevel }
+ Not yet implemented.
+\end{description}
+
+The {\bf Volume} record is a bit special in that it must be the first record.
+The other keyword records may appear in any order and any number following a
+Volume record.
+
+Multiple Volume records may be specified in the same bootstrap file, but each
+one starts a new set of filter criteria for the Volume.
+
+In processing the bootstrap file within the current Volume, each filter
+specified by a keyword is {\bf AND}ed with the next. Thus,
+
+\footnotesize
+\begin{verbatim}
+Volume = Test-01
+Client = "My machine"
+FileIndex = 1
+\end{verbatim}
+\normalsize
+
+will match records on Volume {\bf Test-01} {\bf AND} Client records for {\bf
+My machine} {\bf AND} FileIndex equal to {\bf one}.
+
+Multiple occurrences of the same record are {\bf OR}ed together. Thus,
+
+\footnotesize
+\begin{verbatim}
+Volume = Test-01
+Client = "My machine"
+Client = "Backup machine"
+FileIndex = 1
+\end{verbatim}
+\normalsize
+
+will match records on Volume {\bf Test-01} {\bf AND} (Client records for {\bf
+My machine} {\bf OR} {\bf Backup machine}) {\bf AND} FileIndex equal to {\bf
+one}.
+
+For integer values, you may supply a range or a list, and for all other values
+except Volumes, you may specify a list. A list is equivalent to multiple
+records of the same keyword. For example,
+
+\footnotesize
+\begin{verbatim}
+Volume = Test-01
+Client = "My machine", "Backup machine"
+FileIndex = 1-20, 35
+\end{verbatim}
+\normalsize
+
+will match records on Volume {\bf Test-01} {\bf AND} {\bf (}Client records for
+{\bf My machine} {\bf OR} {\bf Backup machine}{\bf )} {\bf AND} {\bf
+(}FileIndex 1 {\bf OR} 2 {\bf OR} 3 ... {\bf OR} 20 {\bf OR} 35{\bf )}.
+
+As previously mentioned above, there may be multiple Volume records in the
+same bootstrap file. Each new Volume definition begins a new set of filter
+conditions that apply to that Volume and will be {\bf OR}ed with any other
+Volume definitions.
+
+As an example, suppose we query for the current set of tapes to restore all
+files on Client {\bf Rufus} using the {\bf query} command in the console
+program:
+
+\footnotesize
+\begin{verbatim}
+Using default Catalog name=MySQL DB=bacula
+*query
+Available queries:
+ 1: List Job totals:
+ 2: List where a file is saved:
+ 3: List where the most recent copies of a file are saved:
+ 4: List total files/bytes by Job:
+ 5: List total files/bytes by Volume:
+ 6: List last 10 Full Backups for a Client:
+ 7: List Volumes used by selected JobId:
+ 8: List Volumes to Restore All Files:
+Choose a query (1-8): 8
+Enter Client Name: Rufus
++-------+------------------+------------+-----------+----------+------------+
+| JobId | StartTime | VolumeName | StartFile | VolSesId | VolSesTime |
++-------+------------------+------------+-----------+----------+------------+
+| 154 | 2002-05-30 12:08 | test-02 | 0 | 1 | 1022753312 |
+| 202 | 2002-06-15 10:16 | test-02 | 0 | 2 | 1024128917 |
+| 203 | 2002-06-15 11:12 | test-02 | 3 | 1 | 1024132350 |
+| 204 | 2002-06-18 08:11 | test-02 | 4 | 1 | 1024380678 |
++-------+------------------+------------+-----------+----------+------------+
+\end{verbatim}
+\normalsize
+
+The output shows us that there are four Jobs that must be restored. The first
+one is a Full backup, and the following three are all Incremental backups.
+
+The following bootstrap file will restore those files:
+
+\footnotesize
+\begin{verbatim}
+Volume=test-02
+VolSessionId=1
+VolSessionTime=1022753312
+Volume=test-02
+VolSessionId=2
+VolSessionTime=1024128917
+Volume=test-02
+VolSessionId=1
+VolSessionTime=1024132350
+Volume=test-02
+VolSessionId=1
+VolSessionTime=1024380678
+\end{verbatim}
+\normalsize
+
+As a final example, assume that the initial Full save spanned two Volumes. The
+output from {\bf query} might look like:
+
+\footnotesize
+\begin{verbatim}
++-------+------------------+------------+-----------+----------+------------+
+| JobId | StartTime | VolumeName | StartFile | VolSesId | VolSesTime |
++-------+------------------+------------+-----------+----------+------------+
+| 242 | 2002-06-25 16:50 | File0003 | 0 | 1 | 1025016612 |
+| 242 | 2002-06-25 16:50 | File0004 | 0 | 1 | 1025016612 |
+| 243 | 2002-06-25 16:52 | File0005 | 0 | 2 | 1025016612 |
+| 246 | 2002-06-25 19:19 | File0006 | 0 | 2 | 1025025494 |
++-------+------------------+------------+-----------+----------+------------+
+\end{verbatim}
+\normalsize
+
+and the following bootstrap file would restore those files:
+
+\footnotesize
+\begin{verbatim}
+Volume=File0003
+VolSessionId=1
+VolSessionTime=1025016612
+Volume=File0004
+VolSessionId=1
+VolSessionTime=1025016612
+Volume=File0005
+VolSessionId=2
+VolSessionTime=1025016612
+Volume=File0006
+VolSessionId=2
+VolSessionTime=1025025494
+\end{verbatim}
+\normalsize
+
+\section{Automatic Generation of Bootstrap Files}
+\index[general]{Files!Automatic Generation of Bootstrap }
+\index[general]{Automatic Generation of Bootstrap Files }
+
+One thing that is probably worth knowing: the bootstrap files that are
+generated automatically at the end of the job are not as optimized as those
+generated by the restore command. This is because during Incremental and
+Differential jobs, the records pertaining to the files written for the
+Job are appended to the end of the bootstrap file.
+As consequence, all the files saved to an Incremental or Differential job will be
+restored first by the Full save, then by any Incremental or Differential
+saves.
+
+When the bootstrap file is generated for the restore command, only one copy
+(the most recent) of each file is restored.
+
+So if you have spare cycles on your machine, you could optimize the bootstrap
+files by doing the following:
+
+\footnotesize
+\begin{verbatim}
+ ./bconsole
+ restore client=xxx select all
+ done
+ no
+ quit
+ Backup bootstrap file.
+\end{verbatim}
+\normalsize
+
+The above will not work if you have multiple FileSets because that will be an
+extra prompt. However, the {\bf restore client=xxx select all} builds the
+in-memory tree, selecting everything and creates the bootstrap file.
+
+The {\bf no} answers the {\bf Do you want to run this (yes/mod/no)} question.
+
+\label{bscanBootstrap}
+\section{Bootstrap for bscan}
+\index[general]{bscan}
+\index[general]{bscan!bootstrap}
+\index[general]{bscan bootstrap}
+If you have a very large number of Volumes to scan with {\bf bscan},
+you may exceed the command line limit (511 characters). I that case,
+you can create a simple bootstrap file that consists of only the
+volume names. An example might be:
+
+\footnotesize
+\begin{verbatim}
+Volume="Vol001"
+Volume="Vol002"
+Volume="Vol003"
+Volume="Vol004"
+Volume="Vol005"
+\end{verbatim}
+\normalsize
+
+
+\section{A Final Bootstrap Example}
+\index[general]{Bootstrap Example}
+\index[general]{Example!Bootstrap}
+
+If you want to extract or copy a single Job, you can do it by selecting by
+JobId (code not tested) or better yet, if you know the VolSessionTime and the
+VolSessionId (printed on Job report and in Catalog), specifying this is by far
+the best. Using the VolSessionTime and VolSessionId is the way Bacula does
+restores. A bsr file might look like the following:
+
+\footnotesize
+\begin{verbatim}
+Volume="Vol001"
+VolSessionId=10
+VolSessionTime=1080847820
+\end{verbatim}
+\normalsize
+
+If you know how many files are backed up (on the job report), you can
+enormously speed up the selection by adding (let's assume there are 157
+files):
+
+\footnotesize
+\begin{verbatim}
+FileIndex=1-157
+Count=157
+\end{verbatim}
+\normalsize
+
+Finally, if you know the File number where the Job starts, you can also cause
+bcopy to forward space to the right file without reading every record:
+
+\footnotesize
+\begin{verbatim}
+VolFile=20
+\end{verbatim}
+\normalsize
+
+There is nothing magic or complicated about a BSR file. Parsing it and
+properly applying it within Bacula *is* magic, but you don't need to worry
+about that.
+
+If you want to see a *real* bsr file, simply fire up the {\bf restore} command
+in the console program, select something, then answer no when it prompts to
+run the job. Then look at the file {\bf restore.bsr} in your working
+directory.

+\section{Bacula Bugs}
+\label{BugsChapter}
+\index[general]{Bacula Bugs }
+\index[general]{Bugs!Bacula }
+
+Well fortunately there are not too many bugs, but thanks to Dan Langille, we
+have a
+\elink{bugs database}{http://bugs.bacula.org} where bugs are reported.
+Generally, when a bug is fixed, a patch for the currently released version will
+be attached to the bug report.
+
+The directory {\bf patches} in the current SVN always contains a list of
+the patches that have been created for the previously released version
+of Bacula. In addition, the file {\bf patches-version-number} in the
+{\bf patches} directory contains a summary of each of the patches.
+
+A "raw" list of the current task list and known issues can be found in {\bf
+kernstodo} in the main Bacula source directory.

+\chapter{Data Encryption}
+\label{DataEncryption}
+\index[general]{Data Encryption}
+\index[general]{Encryption!Data}
+\index[general]{Data Encryption}
+
+Bacula permits file data encryption and signing within the File Daemon (or
+Client) prior to sending data to the Storage Daemon. Upon restoration,
+file signatures are validated and any mismatches are reported. At no time
+does the Director or the Storage Daemon have access to unencrypted file
+contents.
+
+
+It is very important to specify what this implementation does NOT
+do:
+\begin{itemize}
+\item There is one important restore problem to be aware of, namely, it's
+ possible for the director to restore new keys or a Bacula configuration
+ file to the client, and thus force later backups to be made with a
+ compromised key and/or with no encryption at all. You can avoid this by
+ not changing the location of the keys in your Bacula File daemon
+ configuration file, and not changing your File daemon keys. If you do
+ change either one, you must ensure that no restore is done that restores
+ the old configuration or the old keys. In general, the worst effect of
+ this will be that you can no longer connect the File daemon.
+
+\item The implementation does not encrypt file metadata such as file path
+ names, permissions, and ownership. Extended attributes are also currently
+ not encrypted. However, Mac OS X resource forks are encrypted.
+\end{itemize}
+
+Encryption and signing are implemented using RSA private keys coupled with
+self-signed x509 public certificates. This is also sometimes known as PKI
+or Public Key Infrastructure.
+
+Each File Daemon should be given its own unique private/public key pair.
+In addition to this key pair, any number of "Master Keys" may be specified
+-- these are key pairs that may be used to decrypt any backups should the
+File Daemon key be lost. Only the Master Key's public certificate should
+be made available to the File Daemon. Under no circumstances should the
+Master Private Key be shared or stored on the Client machine.
+
+The Master Keys should be backed up to a secure location, such as a CD
+placed in a in a fire-proof safe or bank safety deposit box. The Master
+Keys should never be kept on the same machine as the Storage Daemon or
+Director if you are worried about an unauthorized party compromising either
+machine and accessing your encrypted backups.
+
+While less critical than the Master Keys, File Daemon Keys are also a prime
+candidate for off-site backups; burn the key pair to a CD and send the CD
+home with the owner of the machine.
+
+NOTE!!! If you lose your encryption keys, backups will be unrecoverable.
+{\bf ALWAYS} store a copy of your master keys in a secure, off-site location.
+
+The basic algorithm used for each backup session (Job) is:
+\begin{enumerate}
+\item The File daemon generates a session key.
+\item The FD encrypts that session key via PKE for all recipients (the file
+daemon, any master keys).
+\item The FD uses that session key to perform symmetric encryption on the data.
+\end{enumerate}
+
+
+\section{Building Bacula with Encryption Support}
+\index[general]{Building Bacula with Encryption Support}
+
+The configuration option for enabling OpenSSL encryption support has not changed
+since Bacula 1.38. To build Bacula with encryption support, you will need
+the OpenSSL libraries and headers installed. When configuring Bacula, use:
+
+\begin{verbatim}
+ ./configure --with-openssl ...
+\end{verbatim}
+
+\section{Encryption Technical Details}
+\index[general]{Encryption Technical Details}
+
+The implementation uses 128bit AES-CBC, with RSA encrypted symmetric
+session keys. The RSA key is user supplied.
+If you are running OpenSSL 0.9.8 or later, the signed file hash uses
+SHA-256 -- otherwise, SHA-1 is used.
+
+End-user configuration settings for the algorithms are not currently
+exposed -- only the algorithms listed above are used. However, the
+data written to Volume supports arbitrary symmetric, asymmetric, and
+digest algorithms for future extensibility, and the back-end
+implementation currently supports:
+
+\begin{verbatim}
+Symmetric Encryption:
+ - 128, 192, and 256-bit AES-CBC
+ - Blowfish-CBC
+
+Asymmetric Encryption (used to encrypt symmetric session keys):
+ - RSA
+
+Digest Algorithms:
+ - MD5
+ - SHA1
+ - SHA256
+ - SHA512
+\end{verbatim}
+
+The various algorithms are exposed via an entirely re-usable,
+OpenSSL-agnostic API (ie, it is possible to drop in a new encryption
+backend). The Volume format is DER-encoded ASN.1, modeled after the
+Cryptographic Message Syntax from RFC 3852. Unfortunately, using CMS
+directly was not possible, as at the time of coding a free software
+streaming DER decoder/encoder was not available.
+
+
+\section{Decrypting with a Master Key}
+\index[general]{Decrypting with a Master Key}
+
+It is preferable to retain a secure, non-encrypted copy of the
+client's own encryption keypair. However, should you lose the
+client's keypair, recovery with the master keypair is possible.
+
+You must:
+\begin{itemize}
+\item Concatenate the master private and public key into a single
+ keypair file, ie:
+ cat master.key master.cert \gt master.keypair
+
+\item Set the PKI Keypair statement in your bacula configuration file:
+
+\begin{verbatim}
+ PKI Keypair = master.keypair
+\end{verbatim}
+
+\item Start the restore. The master keypair will be used to decrypt
+ the file data.
+
+\end{itemize}
+
+
+\section{Generating Private/Public Encryption Keys}
+\index[general]{Generating Private/Public Encryption Keypairs}
+
+Generate a Master Key Pair with:
+
+\footnotesize
+\begin{verbatim}
+ openssl genrsa -out master.key 2048
+ openssl req -new -key master.key -x509 -out master.cert
+\end{verbatim}
+\normalsize
+
+Generate a File Daemon Key Pair for each FD:
+
+\footnotesize
+\begin{verbatim}
+ openssl genrsa -out fd-example.key 2048
+ openssl req -new -key fd-example.key -x509 -out fd-example.cert
+ cat fd-example.key fd-example.cert >fd-example.pem
+\end{verbatim}
+\normalsize
+
+Note, there seems to be a lot of confusion around the file extensions given
+to these keys. For example, a .pem file can contain all the following:
+private keys (RSA and DSA), public keys (RSA and DSA) and (x509) certificates.
+It is the default format for OpenSSL. It stores data Base64 encoded DER format,
+surrounded by ASCII headers, so is suitable for text mode transfers between
+systems. A .pem file may contain any number of keys either public or
+private. We use it in cases where there is both a public and a private
+key.
+
+Typically, above we have used the .cert extension to refer to X509
+certificate encoding that contains only a single public key.

+\chapter{Basic Volume Management}
+\label{DiskChapter}
+\index[general]{Basic Volume Management}
+\index[general]{Management!Basic Volume}
+\index[general]{Disk Volumes}
+
+This chapter presents most all the features needed to do Volume management.
+Most of the concepts apply equally well to both tape and disk Volumes.
+However, the chapter was originally written to explain backing up to disk, so
+you will see it is slanted in that direction, but all the directives
+presented here apply equally well whether your volume is disk or tape.
+
+If you have a lot of hard disk storage or you absolutely must have your
+backups run within a small time window, you may want to direct Bacula to
+backup to disk Volumes rather than tape Volumes. This chapter is intended to
+give you some of the options that are available to you so that you can manage
+either disk or tape volumes.
+
+\label{Concepts}
+\section{Key Concepts and Resource Records}
+\index[general]{Key Concepts and Resource Records }
+\index[general]{Records!Key Concepts and Resource }
+
+Getting Bacula to write to disk rather than tape in the simplest case is
+rather easy. In the Storage daemon's configuration file, you simply define an
+{\bf Archive Device} to be a directory. For example, if you want your disk
+backups to go into the directory {\bf /home/bacula/backups}, you could use the
+following:
+
+\footnotesize
+\begin{verbatim}
+Device {
+ Name = FileBackup
+ Media Type = File
+ Archive Device = /home/bacula/backups
+ Random Access = Yes;
+ AutomaticMount = yes;
+ RemovableMedia = no;
+ AlwaysOpen = no;
+}
+\end{verbatim}
+\normalsize
+
+Assuming you have the appropriate {\bf Storage} resource in your Director's
+configuration file that references the above Device resource,
+
+\footnotesize
+\begin{verbatim}
+Storage {
+ Name = FileStorage
+ Address = ...
+ Password = ...
+ Device = FileBackup
+ Media Type = File
+}
+\end{verbatim}
+\normalsize
+
+Bacula will then write the archive to the file {\bf
+/home/bacula/backups/\lt{}volume-name\gt{}} where \lt{}volume-name\gt{} is the
+volume name of a Volume defined in the Pool. For example, if you have labeled
+a Volume named {\bf Vol001}, Bacula will write to the file {\bf
+/home/bacula/backups/Vol001}. Although you can later move the archive file to
+another directory, you should not rename it or it will become unreadable by
+Bacula. This is because each archive has the filename as part of the internal
+label, and the internal label must agree with the system filename before
+Bacula will use it.
+
+Although this is quite simple, there are a number of problems. The first is
+that unless you specify otherwise, Bacula will always write to the same volume
+until you run out of disk space. This problem is addressed below.
+
+In addition, if you want to use concurrent jobs that write to several
+different volumes at the same time, you will need to understand a number
+of other details. An example of such a configuration is given
+at the end of this chapter under \ilink{Concurrent Disk
+Jobs}{ConcurrentDiskJobs}.
+
+\subsection{Pool Options to Limit the Volume Usage}
+\index[general]{Usage!Pool Options to Limit the Volume }
+\index[general]{Pool Options to Limit the Volume Usage }
+
+Some of the options you have, all of which are specified in the Pool record,
+are:
+
+\begin{itemize}
+\item To write each Volume only once (i.e. one Job per Volume or file in this
+ case), use:
+
+{\bf UseVolumeOnce = yes}.
+
+\item To write nnn Jobs to each Volume, use:
+
+ {\bf Maximum Volume Jobs = nnn}.
+
+\item To limit the maximum size of each Volume, use:
+
+ {\bf Maximum Volume Bytes = mmmm}.
+
+ Note, if you use disk volumes, with all versions up to and including
+ 1.39.28, you should probably limit the Volume size to some reasonable
+ value such as say 5GB. This is because during a restore, Bacula is
+ currently unable to seek to the proper place in a disk volume to restore
+ a file, which means that it must read all records up to where the
+ restore begins. If your Volumes are 50GB, reading half or more of the
+ volume could take quite a bit of time. Also, if you ever have a partial
+ hard disk failure, you are more likely to be able to recover more data
+ if they are in smaller Volumes.
+
+\item To limit the use time (i.e. write the Volume for a maximum of five days),
+ use:
+
+{\bf Volume Use Duration = ttt}.
+\end{itemize}
+
+Note that although you probably would not want to limit the number of bytes on
+a tape as you would on a disk Volume, the other options can be very useful in
+limiting the time Bacula will use a particular Volume (be it tape or disk).
+For example, the above directives can allow you to ensure that you rotate
+through a set of daily Volumes if you wish.
+
+As mentioned above, each of those directives is specified in the Pool or
+Pools that you use for your Volumes. In the case of {\bf Maximum Volume Job},
+{\bf Maximum Volume Bytes}, and {\bf Volume Use Duration}, you can actually
+specify the desired value on a Volume by Volume basis. The value specified in
+the Pool record becomes the default when labeling new Volumes. Once a Volume
+has been created, it gets its own copy of the Pool defaults, and subsequently
+changing the Pool will have no effect on existing Volumes. You can either
+manually change the Volume values, or refresh them from the Pool defaults using
+the {\bf update volume} command in the Console. As an example
+of the use of one of the above, suppose your Pool resource contains:
+
+\footnotesize
+\begin{verbatim}
+Pool {
+ Name = File
+ Pool Type = Backup
+ Volume Use Duration = 23h
+}
+\end{verbatim}
+\normalsize
+
+then if you run a backup once a day (every 24 hours), Bacula will use a new
+Volume for each backup, because each Volume it writes can only be used for 23 hours
+after the first write. Note, setting the use duration to 23 hours is not a very
+good solution for tapes unless you have someone on-site during the weekends,
+because Bacula will want a new Volume and no one will be present to mount it,
+so no weekend backups will be done until Monday morning.
+
+\label{AutomaticLabeling}
+\subsection{Automatic Volume Labeling}
+\index[general]{Automatic Volume Labeling }
+\index[general]{Labeling!Automatic Volume }
+
+Use of the above records brings up another problem -- that of labeling your
+Volumes. For automated disk backup, you can either manually label each of your
+Volumes, or you can have Bacula automatically label new Volumes when they are
+needed. While, the automatic Volume labeling in version 1.30 and prior is a
+bit simplistic, but it does allow for automation, the features added in
+version 1.31 permit automatic creation of a wide variety of labels including
+information from environment variables and special Bacula Counter variables.
+In version 1.37 and later, it is probably much better to use Python scripting
+and the NewVolume event since generating Volume labels in a Python script is
+much easier than trying to figure out Counter variables. See the
+\ilink{Python Scripting}{PythonChapter} chapter of this manual for more
+details.
+
+Please note that automatic Volume labeling can also be used with tapes, but
+it is not nearly so practical since the tapes must be pre-mounted. This
+requires some user interaction. Automatic labeling from templates does NOT
+work with autochangers since Bacula will not access unknown slots. There
+are several methods of labeling all volumes in an autochanger magazine.
+For more information on this, please see the \ilink{
+Autochanger}{AutochangersChapter} chapter of this manual.
+
+Automatic Volume labeling is enabled by making a change to both the Pool
+resource (Director) and to the Device resource (Storage daemon) shown above.
+In the case of the Pool resource, you must provide Bacula with a label format
+that it will use to create new names. In the simplest form, the label format
+is simply the Volume name, to which Bacula will append a four digit number.
+This number starts at 0001 and is incremented for each Volume the catalog
+contains. Thus if you modify your Pool resource to be:
+
+\footnotesize
+\begin{verbatim}
+Pool {
+ Name = File
+ Pool Type = Backup
+ Volume Use Duration = 23h
+ LabelFormat = "Vol"
+}
+\end{verbatim}
+\normalsize
+
+Bacula will create Volume names Vol0001, Vol0002, and so on when new Volumes
+are needed. Much more complex and elaborate labels can be created using
+variable expansion defined in the
+\ilink{Variable Expansion}{VarsChapter} chapter of this manual.
+
+The second change that is necessary to make automatic labeling work is to give
+the Storage daemon permission to automatically label Volumes. Do so by adding
+{\bf LabelMedia = yes} to the Device resource as follows:
+
+\footnotesize
+\begin{verbatim}
+Device {
+ Name = File
+ Media Type = File
+ Archive Device = /home/bacula/backups
+ Random Access = Yes;
+ AutomaticMount = yes;
+ RemovableMedia = no;
+ AlwaysOpen = no;
+ LabelMedia = yes
+}
+\end{verbatim}
+\normalsize
+
+You can find more details of the {\bf Label Format} Pool record in
+\ilink{Label Format}{Label} description of the Pool resource
+records.
+
+\label{Recycling1}
+\subsection{Restricting the Number of Volumes and Recycling}
+\index[general]{Recycling!Restricting the Number of Volumes and Recycling}
+\index[general]{Restricting the Number of Volumes and Recycling}
+
+Automatic labeling discussed above brings up the problem of Volume management.
+With the above scheme, a new Volume will be created every day. If you have not
+specified Retention periods, your Catalog will continue to fill keeping track
+of all the files Bacula has backed up, and this procedure will create one new
+archive file (Volume) every day.
+
+The tools Bacula gives you to help automatically manage these problems are the
+following:
+
+\begin{enumerate}
+\item Catalog file record retention periods, the
+ \ilink{File Retention = ttt}{FileRetention} record in the Client
+ resource.
+\item Catalog job record retention periods, the
+ \ilink{Job Retention = ttt}{JobRetention} record in the Client
+ resource.
+\item The
+ \ilink{ AutoPrune = yes}{AutoPrune} record in the Client resource
+ to permit application of the above two retention periods.
+\item The
+ \ilink{ Volume Retention = ttt}{VolRetention} record in the Pool
+ resource.
+\item The
+ \ilink{ AutoPrune = yes}{PoolAutoPrune} record in the Pool
+ resource to permit application of the Volume retention period.
+\item The
+ \ilink{ Recycle = yes}{PoolRecycle} record in the Pool resource
+ to permit automatic recycling of Volumes whose Volume retention period has
+ expired.
+\item The
+ \ilink{ Recycle Oldest Volume = yes}{RecycleOldest} record in the
+ Pool resource tells Bacula to Prune the oldest volume in the Pool, and if all
+ files were pruned to recycle this volume and use it.
+\item The
+ \ilink{ Recycle Current Volume = yes}{RecycleCurrent} record in
+ the Pool resource tells Bacula to Prune the currently mounted volume in the
+ Pool, and if all files were pruned to recycle this volume and use it.
+\item The
+ \ilink{ Purge Oldest Volume = yes}{PurgeOldest} record in the
+ Pool resource permits a forced recycling of the oldest Volume when a new one
+ is needed. {\bf N.B. This record ignores retention periods! We highly
+ recommend not to use this record, but instead use Recycle Oldest Volume}
+\item The
+ \ilink{ Maximum Volumes = nnn}{MaxVolumes} record in the Pool
+ resource to limit the number of Volumes that can be created.
+\end{enumerate}
+
+The first three records (File Retention, Job Retention, and AutoPrune)
+determine the amount of time that Job and File records will remain in your
+Catalog, and they are discussed in detail in the
+\ilink{Automatic Volume Recycling}{RecyclingChapter} chapter of
+this manual.
+
+Volume Retention, AutoPrune, and Recycle determine how long Bacula will keep
+your Volumes before reusing them, and they are also discussed in detail in the
+\ilink{Automatic Volume Recycling}{RecyclingChapter} chapter of
+this manual.
+
+The Maximum Volumes record can also be used in conjunction with the Volume
+Retention period to limit the total number of archive Volumes (files) that
+Bacula will create. By setting an appropriate Volume Retention period, a
+Volume will be purged just before it is needed and thus Bacula can cycle
+through a fixed set of Volumes. Cycling through a fixed set of Volumes can
+also be done by setting {\bf Recycle Oldest Volume = yes} or {\bf Recycle
+Current Volume = yes}. In this case, when Bacula needs a new Volume, it will
+prune the specified volume.
+
+\label{ConcurrentDiskJobs}
+\section{Concurrent Disk Jobs}
+\index[general]{Concurrent Disk Jobs}
+Above, we discussed how you could have a single device named {\bf
+FileBackup} that writes to volumes in {\bf /home/bacula/backups}.
+You can, in fact, run multiple concurrent jobs using the
+Storage definition given with this example, and all the jobs will
+simultaneously write into the Volume that is being written.
+
+Now suppose you want to use multiple Pools, which means multiple
+Volumes, or suppose you want each client to have its own Volume
+and perhaps its own directory such as {\bf /home/bacula/client1}
+and {\bf /home/bacula/client2} ... With the single Storage and Device
+definition above, neither of these two is possible. Why? Because
+Bacula disk storage follows the same rules as tape devices. Only
+one Volume can be mounted on any Device at any time. If you want
+to simultaneously write multiple Volumes, you will need multiple
+Device resources in your bacula-sd.conf file, and thus multiple
+Storage resources in your bacula-dir.conf.
+
+OK, so now you should understand that you need multiple Device definitions
+in the case of different directories or different Pools, but you also
+need to know that the catalog data that Bacula keeps contains only
+the Media Type and not the specific storage device. This permits a tape
+for example to be re-read on any compatible tape drive. The compatibility
+being determined by the Media Type. The same applies to disk storage.
+Since a volume that is written by a Device in say directory {\bf
+/home/bacula/backups} cannot be read by a Device with an Archive Device
+definition of {\bf /home/bacula/client1}, you will not be able to
+restore all your files if you give both those devices
+{\bf Media Type = File}. During the restore, Bacula will simply choose
+the first available device, which may not be the correct one. If this
+is confusing, just remember that the Directory has only the Media Type
+and the Volume name. It does not know the {\bf Archive Device} (or the
+full path) that is specified in the Storage daemon. Thus you must
+explicitly tie your Volumes to the correct Device by using the Media Type.
+
+The example shown below shows a case where there are two clients, each
+using its own Pool and storing their Volumes in different directories.
+
+
+\label{Example2}
+\section{An Example}
+\index[general]{Example }
+
+The following example is not very practical, but can be used to demonstrate
+the proof of concept in a relatively short period of time. The example
+consists of a two clients that are backed up to a set of 12 archive files
+(Volumes) for each client into different directories on the Storage
+machine. Each Volume is used (written) only once, and there are four Full
+saves done every hour (so the whole thing cycles around after three hours).
+
+What is key here is that each physical device on the Storage daemon
+has a different Media Type. This allows the Director to choose the
+correct device for restores ...
+
+The Director's configuration file is as follows:
+
+\footnotesize
+\begin{verbatim}
+Director {
+ Name = my-dir
+ QueryFile = "~/bacula/bin/query.sql"
+ PidDirectory = "~/bacula/working"
+ WorkingDirectory = "~/bacula/working"
+ Password = dir_password
+}
+Schedule {
+ Name = "FourPerHour"
+ Run = Level=Full hourly at 0:05

+\label{MultipleDisks}
+\section{Backing up to Multiple Disks}
+\index[general]{Disks!Backing up to Multiple }
+\index[general]{Backing up to Multiple Disks }
+
+Bacula can, of course, use multiple disks, but in general, each disk must be a
+separate Device specification in the Storage daemon's conf file, and you must
+then select what clients to backup to each disk. You will also want to
+give each Device specification a different Media Type so that during
+a restore, Bacula will be able to find the appropriate drive.
+
+The situation is a bit more complicated if you want to treat two different
+physical disk drives (or partitions) logically as a single drive, which
+Bacula does not directly support. However, it is possible to back up your
+data to multiple disks as if they were a single drive by linking the
+Volumes from the first disk to the second disk.
+
+For example, assume that you have two disks named {\bf /disk1} and {\bf
+/disk2}. If you then create a standard Storage daemon Device resource for
+backing up to the first disk, it will look like the following:
+
+\footnotesize
+\begin{verbatim}
+Device {
+ Name = client1
+ Media Type = File
+ Archive Device = /disk1
+ LabelMedia = yes;
+ Random Access = Yes;
+ AutomaticMount = yes;
+ RemovableMedia = no;
+ AlwaysOpen = no;
+}
+\end{verbatim}
+\normalsize
+
+Since there is no way to get the above Device resource to reference both {\bf
+/disk1} and {\bf /disk2} we do it by pre-creating Volumes on /disk2 with the
+following:
+
+\footnotesize
+\begin{verbatim}
+ln -s /disk2/Disk2-vol001 /disk1/Disk2-vol001
+ln -s /disk2/Disk2-vol002 /disk1/Disk2-vol002
+ln -s /disk2/Disk2-vol003 /disk1/Disk2-vol003
+...
+\end{verbatim}
+\normalsize
+
+At this point, you can label the Volumes as Volume {\bf Disk2-vol001}, {\bf
+Disk2-vol002}, ... and Bacula will use them as if they were on /disk1 but
+actually write the data to /disk2. The only minor inconvenience with this
+method is that you must explicitly name the disks and cannot use automatic
+labeling unless you arrange to have the labels exactly match the links you
+have created.
+
+An important thing to know is that Bacula treats disks like tape drives
+as much as it can. This means that you can only have a single Volume
+mounted at one time on a disk as defined in your Device resource in
+the Storage daemon's conf file. You can have multiple concurrent
+jobs running that all write to the one Volume that is being used, but
+if you want to have multiple concurrent jobs that are writing to
+separate disks drives (or partitions), you will need to define
+separate Device resources for each one, exactly as you would do for
+two different tape drives. There is one fundamental difference, however.
+The Volumes that you create on the two drives cannot be easily exchanged
+as they can for a tape drive, because they are physically resident (already
+mounted in a sense) on the particular drive. As a consequence, you will
+probably want to give them different Media Types so that Bacula can
+distinguish what Device resource to use during a restore.
+An example would be the following:
+
+\footnotesize
+\begin{verbatim}
+Device {
+ Name = Disk1
+ Media Type = File1
+ Archive Device = /disk1
+ LabelMedia = yes;
+ Random Access = Yes;
+ AutomaticMount = yes;
+ RemovableMedia = no;
+ AlwaysOpen = no;
+}
+
+Device {
+ Name = Disk2
+ Media Type = File2
+ Archive Device = /disk2
+ LabelMedia = yes;
+ Random Access = Yes;
+ AutomaticMount = yes;
+ RemovableMedia = no;
+ AlwaysOpen = no;
+}
+\end{verbatim}
+\normalsize
+
+With the above device definitions, you can run two concurrent
+jobs each writing at the same time, one to {\bf /disk1} and the
+other to {\bf /disk2}. The fact that you have given them different
+Media Types will allow Bacula to quickly choose the correct
+Storage resource in the Director when doing a restore.
+
+\label{MultipleClients}
+\section{Considerations for Multiple Clients}
+\index[general]{Clients!Considerations for Multiple }
+\index[general]{Multiple Clients}
+
+If we take the above example and add a second Client, here are a few
+considerations:
+
+\begin{itemize}
+\item Although the second client can write to the same set of Volumes, you
+ will probably want to write to a different set.
+\item You can write to a different set of Volumes by defining a second Pool,
+ which has a different name and a different {\bf LabelFormat}.
+\item If you wish the Volumes for the second client to go into a different
+ directory (perhaps even on a different filesystem to spread the load), you
+ would do so by defining a second Device resource in the Storage daemon. The
+{\bf Name} must be different, and the {\bf Archive Device} could be
+different. To ensure that Volumes are never mixed from one pool to another,
+you might also define a different MediaType (e.g. {\bf File1}).
+\end{itemize}
+
+In this example, we have two clients, each with a different Pool and a
+different number of archive files retained. They also write to different
+directories with different Volume labeling.
+
+The Director's configuration file is as follows:
+
+\footnotesize
+\begin{verbatim}
+Director {
+ Name = my-dir
+ QueryFile = "~/bacula/bin/query.sql"
+ PidDirectory = "~/bacula/working"

+\index[general]{DVD Volumes}
+\index[general]{Writing DVDs}
+\index[general]{DVD Writing}
+\index[general]{Volumes!DVD}
+
+Bacula allows you to specify that you want to write to DVD. However,
+this feature is implemented only in version 1.37 or later.
+You may in fact write to DVD+RW, DVD+R, DVD-R, or DVD-RW
+media. The actual process used by Bacula is to first write
+the image to a spool directory, then when the Volume reaches
+a certain size or, at your option, at the end of a Job, Bacula
+will transfer the image from the spool directory to the
+DVD. The actual work of transferring the image is done
+by a script {\bf dvd-handler}, and the heart of that
+script is a program called {\bf growisofs} which allows
+creating or adding to a DVD ISO filesystem.
+
+You must have {\bf dvd+rw-tools} loaded on your system for DVD writing to
+work. Please note that the original {\bf dvd+rw-tools} package does {\bf
+NOT} work with Bacula. You must apply a patch which can be found in the
+{\bf patches} directory of Bacula sources with the name
+{\bf dvd+rw-tools-5.21.4.10.8.bacula.patch} for version 5.21 of the tools,
+or patch {bf dvd+rw-tools-6.1.bacula.patch} if you have version 6.1
+on your system. Unfortunately, this requires you to build the dvd\_rw-tools
+from source.
+
+Note, some Linux distros such as Debian dvd+rw-tools-7.0-4 package already
+have the patch applied, so please check.
+
+The fact that Bacula cannot use the OS to write directly
+to the DVD makes the whole process a bit more error prone than
+writing to a disk or a tape, but nevertheless, it does work if you
+use some care to set it up properly. However, at the current time
+(version 1.39.30 -- 12 December 2006) we still consider this code to be
+BETA quality. As a consequence, please do careful testing before relying
+on DVD backups in production.
+
+The remainder of this chapter explains the various directives that you can
+use to control the DVD writing.
+
+\label{DVDdirectives}
+\section{DVD Specific SD Directives}
+\index[general]{Directives!DVD}
+\index[general]{DVD Specific SD Directives }
+
+The following directives are added to the Storage daemon's
+Device resource.
+
+\begin{description}
+
+\item [Requires Mount = {\it Yes|No}]
+ \index[sd]{Requires Mount }
+ You must set this directive to {\bf yes} for DVD-writers, and to {\bf no} for
+ all other devices (tapes/files). This directive indicates if the device
+ requires to be mounted using the {\bf Mount Command}.
+ To be able to write a DVD, the following directives must also be
+ defined: {\bf Mount Point}, {\bf Mount Command}, {\bf Unmount Command} and
+ {\bf Write Part Command}.
+
+\item [Mount Point = {\it directory}]
+ \index[sd]{Mount Point}
+ Directory where the device can be mounted.
+
+\item [Mount Command = {\it name-string}]
+ \index[sd]{Mount Command}
+ Command that must be executed to mount the device. Although the
+ device is written directly, the mount command is necessary in
+ order to determine the free space left on the DVD. Before the command is
+ executed, \%a is replaced with the Archive Device, and \%m with the Mount
+ Point.
+
+ Most frequently, you will define it as follows:
+
+\footnotesize
+\begin{verbatim}
+ Mount Command = "/bin/mount -t iso9660 -o ro %a %m"
+\end{verbatim}
+\normalsize
+
+However, if you have defined a mount point in /etc/fstab, you might be
+able to use a mount command such as:
+
+\footnotesize
+\begin{verbatim}
+ Mount Command = "/bin/mount /media/dvd"
+\end{verbatim}
+\normalsize
+
+
+\item [Unmount Command = {\it name-string}]
+ \index[sd]{Unmount Command}
+ Command that must be executed to unmount the device. Before the command is
+ executed, \%a is replaced with the Archive Device, and \%m with the Mount
+ Point.
+
+ Most frequently, you will define it as follows:
+
+\footnotesize
+\begin{verbatim}
+ Unmount Command = "/bin/umount %m"
+\end{verbatim}
+\normalsize
+
+\item [Write Part Command = {\it name-string}]
+ \index[sd]{Write Part Command }
+ Command that must be executed to write a part to the device. Before the
+ command is executed, \%a is replaced with the Archive Device, \%m with the
+ Mount Point, \%e is replaced with 1 if we are writing the first part,
+ and with 0 otherwise, and \%v with the current part filename.
+
+ For a DVD, you will most frequently specify the Bacula supplied {\bf
+ dvd-handler} script as follows:
+
+\footnotesize
+\begin{verbatim}
+ Write Part Command = "/path/dvd-handler %a write %e %v"
+\end{verbatim}
+\normalsize
+
+ Where {\bf /path} is the path to your scripts install directory, and
+ dvd-handler is the Bacula supplied script file.
+ This command will already be present, but commented out,
+ in the default bacula-sd.conf file. To use it, simply remove
+ the comment (\#) symbol.
+
+
+\item [Free Space Command = {\it name-string}]
+ \index[sd]{Free Space Command }
+ Command that must be executed to check how much free space is left on the
+ device. Before the command is executed,\%a is replaced with the Archive
+ Device.
+
+ For a DVD, you will most frequently specify the Bacula supplied {\bf
+ dvd-handler} script as follows:
+
+\footnotesize
+\begin{verbatim}
+ Free Space Command = "/path/dvd-handler %a free"
+\end{verbatim}
+\normalsize
+
+ Where {\bf /path} is the path to your scripts install directory, and
+ dvd-handler is the Bacula supplied script file.
+ If you want to specify your own command, please look at the code in
+ dvd-handler to see what output Bacula expects from this command.
+ This command will already be present, but commented out,
+ in the default bacula-sd.conf file. To use it, simply remove
+ the comment (\#) symbol.
+
+ If you do not set it, Bacula will expect there is always free space on the
+ device.
+
+\end{description}
+
+In addition to the directives specified above, you must also
+specify the other standard Device resource directives. Please see the
+sample DVD Device resource in the default bacula-sd.conf file. Be sure
+to specify the raw device name for {\bf Archive Device}. It should
+be a name such as {\bf /dev/cdrom} or {\bf /media/cdrecorder} or
+{\bf /dev/dvd} depending on your system. It will not be a name such
+as {\bf /mnt/cdrom}.
+
+Finally, for {\bf growisofs} to work, it must be able to lock
+a certain amount of memory in RAM. If you have restrictions on
+this function, you may have failures. Under {\bf bash}, you can
+set this with the following command:
+
+\footnotesize
+\begin{verbatim}
+ulimit -l unlimited
+\end{verbatim}
+\normalsize
+
+\section{Edit Codes for DVD Directives}
+\index[general]{Directives!DVD Edit Codes}
+\index[general]{Edit Codes for DVD Directives }
+
+Before submitting the {\bf Mount Command}, {\bf Unmount Command},
+{\bf Write Part Command}, or {\bf Free Space Command} directives
+to the operating system, Bacula performs character substitution of the
+following characters:
+
+\footnotesize
+\begin{verbatim}
+ %% = %
+ %a = Archive device name
+ %e = erase (set if cannot mount and first part)
+ %n = part number
+ %m = mount point
+ %v = last part name (i.e. filename)
+\end{verbatim}
+\normalsize
+
+
+
+\section{DVD Specific Director Directives}
+\index[general]{Directives!DVD}
+\index[general]{DVD Specific Director Directives }
+
+The following directives are added to the Director's Job resource.
+
+\label{WritePartAfterJob}
+\begin{description}
+\item [Write Part After Job = \lt{}yes|no\gt{}]
+ \index[dir]{Write Part After Job }
+ If this directive is set to {\bf yes} (default {\bf no}), the
+ Volume written to a temporary spool file for the current Job will
+ be written to the DVD as a new part file
+ will be created after the job is finished.
+
+ It should be set to {\bf yes} when writing to devices that require a mount
+ (for example DVD), so you are sure that the current part, containing
+ this job's data, is written to the device, and that no data is left in
+ the temporary file on the hard disk. However, on some media, like DVD+R
+ and DVD-R, a lot of space (about 10Mb) is lost everytime a part is
+ written. So, if you run several jobs each after another, you could set
+ this directive to {\bf no} for all jobs, except the last one, to avoid
+ wasting too much space, but to ensure that the data is written to the
+ medium when all jobs are finished.
+
+ This directive is ignored for devices other than DVDs.
+\end{description}
+
+
+
+\label{DVDpoints}
+\section{Other Points}
+\index[general]{Points!Other }
+\index[general]{Other Points }
+
+\begin{itemize}
+\item Please be sure that you have any automatic DVD mounting
+ disabled before running Bacula -- this includes auto mounting
+ in /etc/fstab, hotplug, ... If the DVD is automatically
+ mounted by the OS, it will cause problems when Bacula tries
+ to mount/unmount the DVD.
+\item Please be sure that you the directive {\bf Write Part After Job}
+ set to {\bf yes}, otherwise the last part of the data to be
+ written will be left in the DVD spool file and not written to
+ the DVD. The DVD will then be unreadable until this last part
+ is written. If you have a series of jobs that are run one at
+ a time, you can turn this off until the last job is run.
+\item The current code is not designed to have multiple simultaneous
+ jobs writing to the DVD. As a consequence, please ensure that
+ only one DVD backup job runs at any time.
+\item Writing and reading of DVD+RW seems to work quite reliably
+ provided you are using the patched dvd+rw-mediainfo programs.
+ On the other hand, we do not have enough information to ensure
+ that DVD-RW or other forms of DVDs work correctly.
+\item DVD+RW supports only about 1000 overwrites. Every time you
+ mount the filesystem read/write will count as one write. This can
+ add up quickly, so it is best to mount your DVD+RW filesystem read-only.
+ Bacula does not need the DVD to be mounted read-write, since it uses
+ the raw device for writing.
+\item Reformatting DVD+RW 10-20 times can apparently make the medium
+ unusable. Normally you should not have to format or reformat
+ DVD+RW media. If it is necessary, current versions of growisofs will
+ do so automatically.
+\item We have had several problems writing to DVD-RWs (this does NOT
+ concern DVD+RW), because these media have two writing-modes: {\bf
+ Incremental Sequential} and {\bf Restricted Overwrite}. Depending on
+ your device and the media you use, one of these modes may not work
+ correctly (e.g. {\bf Incremental Sequential} does not work with my NEC
+ DVD-writer and Verbatim DVD-RW).
+
+ To retrieve the current mode of a DVD-RW, run:
+\begin{verbatim}
+ dvd+rw-mediainfo /dev/xxx
+\end{verbatim}
+ where you replace xxx with your DVD device name.
+
+ {\bf Mounted Media} line should give you the information.
+
+ To set the device to {\bf Restricted Overwrite} mode, run:
+\begin{verbatim}
+ dvd+rw-format /dev/xxx
+\end{verbatim}
+ If you want to set it back to the default {\bf Incremental Sequential} mode, run:
+\begin{verbatim}
+ dvd+rw-format -blank /dev/xxx
+\end{verbatim}
+
+\item Bacula only accepts to write to blank DVDs. To quickly blank a DVD+/-RW, run
+ this command:
+\begin{verbatim}
+ dd if=/dev/zero bs=1024 count=512 | growisofs -Z /dev/xxx=/dev/fd/0
+\end{verbatim}
+ Then, try to mount the device, if it cannot be mounted, it will be considered
+ as blank by Bacula, if it can be mounted, try a full blank (see below).
+
+\item If you wish to blank completely a DVD+/-RW, use the following:
+\begin{verbatim}
+ growisofs -Z /dev/xxx=/dev/zero
+\end{verbatim}
+ where you replace xxx with your DVD device name. However, note that this
+ blanks the whole DVD, which takes quite a long time (16 minutes on mine).
+\item DVD+RW and DVD-RW support only about 1000 overwrites (i.e. don't use the
+same medium for years if you don't want to have problems...).
+
+To write to the DVD the first time use:
+\begin{verbatim}
+ growisofs -Z /dev/xxx filename
+\end{verbatim}
+
+To add additional files (more parts use):
+
+\begin{verbatim}
+ growisofs -M /dev/xxx filename
+\end{verbatim}
+
+The option {\bf -use-the-force-luke=4gms} was added in growisofs 5.20 to
+override growisofs' behavior of always checking for the 4GB limit.
+Normally, this option is recommended for all Linux 2.6.8 kernels or
+greater, since these newer kernels can handle writing more than 4GB.
+See below for more details on this subject.
+
+\item For more information about DVD writing, please look at the
+\elink{dvd+rw-tools homepage}{http://fy.chalmers.se/~appro/linux/DVD+RW/}.
+
+\item According to bug \#912, bscan cannot read multi-volume DVDs. This is
+on our TODO list, but unless someone submits a patch it is not likely to be
+done any time in the near future. (9 Sept 2007).
+

+software does. But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book. We recommend this License
+principally for works whose purpose is instruction or reference.
+
+
+\begin{center}
+{\Large\bf 1. APPLICABILITY AND DEFINITIONS}
+\end{center}
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License. Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein. The \textbf{"Document"}, below,
+refers to any such manual or work. Any member of the public is a
+licensee, and is addressed as \textbf{"you"}. You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A \textbf{"Modified Version"} of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A \textbf{"Secondary Section"} is a named appendix or a front-matter section of
+the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall subject
+(or to related matters) and contains nothing that could fall directly
+within that overall subject. (Thus, if the Document is in part a
+textbook of mathematics, a Secondary Section may not explain any
+mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The \textbf{"Invariant Sections"} are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License. If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant. The Document may contain zero
+Invariant Sections. If the Document does not identify any Invariant
+Sections then there are none.
+
+The \textbf{"Cover Texts"} are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License. A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A \textbf{"Transparent"} copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text. A copy that is not "Transparent" is called \textbf{"Opaque"}.
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input format, SGML
+or XML using a publicly available DTD, and standard-conforming simple
+HTML, PostScript or PDF designed for human modification. Examples of
+transparent image formats include PNG, XCF and JPG. Opaque formats
+include proprietary formats that can be read and edited only by
+proprietary word processors, SGML or XML for which the DTD and/or
+processing tools are not generally available, and the
+machine-generated HTML, PostScript or PDF produced by some word
+processors for output purposes only.
+
+The \textbf{"Title Page"} means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, "Title Page" means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+A section \textbf{"Entitled XYZ"} means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language. (Here XYZ stands for a
+specific section name mentioned below, such as \textbf{"Acknowledgements"},
+\textbf{"Dedications"}, \textbf{"Endorsements"}, or \textbf{"History"}.)
+To \textbf{"Preserve the Title"}
+of such a section when you modify the Document means that it remains a
+section "Entitled XYZ" according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document. These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+
+\begin{center}
+{\Large\bf 2. VERBATIM COPYING}
+\end{center}
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+
+\begin{center}
+{\Large\bf 3. COPYING IN QUANTITY}
+\end{center}
+
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+
+\begin{center}
+{\Large\bf 4. MODIFICATIONS}
+\end{center}
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+\begin{itemize}
+\item[A.]
+ Use in the Title Page (and on the covers, if any) a title distinct
+ from that of the Document, and from those of previous versions
+ (which should, if there were any, be listed in the History section
+ of the Document). You may use the same title as a previous version
+ if the original publisher of that version gives permission.
+
+\item[B.]
+ List on the Title Page, as authors, one or more persons or entities
+ responsible for authorship of the modifications in the Modified
+ Version, together with at least five of the principal authors of the
+ Document (all of its principal authors, if it has fewer than five),
+ unless they release you from this requirement.
+
+\item[C.]
+ State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+
+\item[D.]
+ Preserve all the copyright notices of the Document.
+
+\item[E.]
+ Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+
+\item[F.]
+ Include, immediately after the copyright notices, a license notice
+ giving the public permission to use the Modified Version under the
+ terms of this License, in the form shown in the Addendum below.
+
+\item[G.]
+ Preserve in that license notice the full lists of Invariant Sections
+ and required Cover Texts given in the Document's license notice.
+
+\item[H.]
+ Include an unaltered copy of this License.
+
+\item[I.]
+ Preserve the section Entitled "History", Preserve its Title, and add
+ to it an item stating at least the title, year, new authors, and
+ publisher of the Modified Version as given on the Title Page. If
+ there is no section Entitled "History" in the Document, create one
+ stating the title, year, authors, and publisher of the Document as
+ given on its Title Page, then add an item describing the Modified
+ Version as stated in the previous sentence.
+
+\item[J.]
+ Preserve the network location, if any, given in the Document for
+ public access to a Transparent copy of the Document, and likewise
+ the network locations given in the Document for previous versions
+ it was based on. These may be placed in the "History" section.
+ You may omit a network location for a work that was published at
+ least four years before the Document itself, or if the original
+ publisher of the version it refers to gives permission.
+
+\item[K.]
+ For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the section all
+ the substance and tone of each of the contributor acknowledgements
+ and/or dedications given therein.
+
+\item[L.]
+ Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section titles.
+
+\item[M.]
+ Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+
+\item[N.]
+ Do not retitle any existing section to be Entitled "Endorsements"
+ or to conflict in title with any Invariant Section.
+
+\item[O.]
+ Preserve any Warranty Disclaimers.
+\end{itemize}
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled "Endorsements", provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+
+\begin{center}
+{\Large\bf 5. COMBINING DOCUMENTS}
+\end{center}
+
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled "History"
+in the various original documents, forming one section Entitled
+"History"; likewise combine any sections Entitled "Acknowledgements",
+and any sections Entitled "Dedications". You must delete all sections
+Entitled "Endorsements".
+
+\begin{center}
+{\Large\bf 6. COLLECTIONS OF DOCUMENTS}
+\end{center}
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+
+\begin{center}
+{\Large\bf 7. AGGREGATION WITH INDEPENDENT WORKS}
+\end{center}
+
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an "aggregate" if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+
+\begin{center}
+{\Large\bf 8. TRANSLATION}
+\end{center}
+
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers. In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled "Acknowledgements",
+"Dedications", or "History", the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+
+\begin{center}
+{\Large\bf 9. TERMINATION}
+\end{center}
+
+
+You may not copy, modify, sublicense, or distribute the Document except
+as expressly provided for under this License. Any other attempt to
+copy, modify, sublicense or distribute the Document is void, and will
+automatically terminate your rights under this License. However,
+parties who have received copies, or rights, from you under this
+License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+
+\begin{center}
+{\Large\bf 10. FUTURE REVISIONS OF THIS LICENSE}
+\end{center}
+
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns. See
+http://www.gnu.org/copyleft/.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation. If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.
+
+
+\begin{center}
+{\Large\bf ADDENDUM: How to use this License for your documents}
+% TODO: this is too long for table of contents
+\end{center}
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+\bigskip
+\begin{quote}
+ Copyright \copyright YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.2
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
+ A copy of the license is included in the section entitled "GNU
+ Free Documentation License".
+\end{quote}
+\bigskip
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the "with...Texts." line with this:
+
+\bigskip
+\begin{quote}
+ with the Invariant Sections being LIST THEIR TITLES, with the
+ Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
+\end{quote}
+\bigskip
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

\chapter{What is Bacula?}
\label{GeneralChapter}
-\index[general]{Bacula!Que es }
-\index[general]{Que es Bacula? }
+\index[general]{Bacula!What is }
+\index[general]{What is Bacula? }
+
+Bacula is a set of computer programs that permits the system
+administrator to manage backup, recovery, and verification of computer data
+across a network of computers of different kinds. Bacula can also run entirely
+upon a single computer and can backup to various types of media, including tape
+and disk.
+
+In technical terms, it is a
+network Client/Server based backup program. Bacula is relatively easy to use
+and efficient, while offering many advanced storage management features that
+make it easy to find and recover lost or damaged files. Due to its modular
+design, Bacula is scalable from small single computer systems to systems
+consisting of hundreds of computers located over a large network.
+
+\section{Who Needs Bacula?}
+\index[general]{Who Needs Bacula? }
+\index[general]{Bacula!Who Needs }
+
+If you are currently using a program such as tar, dump, or
+bru to backup your computer data, and you would like a network solution, more
+flexibility, or catalog services, Bacula will most likely provide the
+additional features you want. However, if you are new to Unix systems or do
+not have offsetting experience with a sophisticated backup package, the Bacula project does not
+recommend using Bacula as it is much more difficult to setup and use than
+tar or dump.
+
+If you want Bacula to behave like the above mentioned simple
+programs and write over any tape that you put in the drive, then you will find
+working with Bacula difficult. Bacula is designed to protect your data
+following the rules you specify, and this means reusing a tape only
+as the last resort. It is possible to "force" Bacula to write
+over any tape in the drive, but it is easier and more efficient to use a
+simpler program for that kind of operation.
+
+If you would like a backup program that can write
+to multiple volumes (i.e. is not limited by your tape drive capacity), Bacula
+can most likely fill your needs. In addition, quite a number of Bacula users
+report that Bacula is simpler to setup and use than other equivalent programs.
+
+If you are currently using a sophisticated commercial package such as Legato
+Networker. ARCserveIT, Arkeia, or PerfectBackup+, you may be interested in
+Bacula, which provides many of the same features and is free software
+available under the GNU Version 2 software license.
+
+\section{Bacula Components or Services}
+\index[general]{Bacula Components or Services }
+\index[general]{Services!Bacula Components or }
+
+Bacula is made up of the following five major components or services:
+Director, Console, File, Storage, and Monitor services.
-Bacula es un conjunto de programas de computadores, que permiten al administrador de sistemas administrar backups, restauraciones y verificación
-de datos a través de la red de computadores de diversas maneras. Puede correr en una sola computadora y se pueden respaldos a varios tipos de media,
-que incluyen cintas y disco.
-
-En términos técnicos, es un programa de respaldo en red basado en ambientes Cliente/Servidor. Bacula es relativamente fácil de utilizar y muy eficiente, además de ofrecer muchas funcionalidades avanzadas de administración de almacenamiento, que hacen mas fácil la búsqueda y recuperación de archivos dañados o perdidos. Gracias a su diseño modular, puede escalar desde una pequeña computadores hasta sistemas conformados por cientos de computadoras, localizadas en una red muy amplia.

-Si actualmente estas utilizando un programa como tar, dump, cpio o rsync para hacer respaldos de los datos de sus computadores o servidores, y le gustaría una solución en red, con mayores facilidades y un servicio de catalogo, Bacula suministrara estas funcionalidades que usted quiere. Sin embargo, si usted tiene poco tiempo utilizando sistemas UNIX o Linux o no tiene mucha experiencia con un paquete sofisticado de respaldo, el proyecto Bacula no recomienda el uso de la aplicación, puesto que puede ser mas complicado que la configuración y uso de los comandos tar o dump.
-
-Si usted quiere que Bacula se comporte como los programas mencionados con anterioridad y que este escriba sobre cualquier cinta que usted coloque en la unidad del drive, se podría conseguir con muchas dificultades. Bacula esta diseñado para proteger la data siguiendo las reglas que los administradores indiquen, y esto significa reutilizar la cinta como el ultimo recurso. Aunque es posible “forzar” a Bacula a escribir sobre cualquier cinta que se encuentre en la unidad, para el uso de estas opciones es preferible y mas sencillo, utilizar un programa simple para manejar esta clase de operaciones.
-
-Si se desea un programa de backup que pueda escribir a multilples volúmenes, es decir, no existan limitaciones en cuanto a la capacidad de las unidades de tape, Bacula puede cumplir con todas sus necesidades. Adicionalmente, un gran numero de usuarios de Bacula reportan que este es mas simple de configurar y utilizar que otros programas equivalentes.
-
-Por ultimo, si actualmente esta utilizando una aplicación comercial de respaldo y recuperación, tales como Legato Networker, ARCserveIT. Arkeia, Data Protector o PerfectBackup+, usted podría estar interesado en Bacula, el cual suministra muchas de las funcionalidades y es un software libre disponible bajo la licencia de software GNU Versión 2.

\subsection*{Bacula Director}
\label{DirDef}
- El servicio de Bacula Director es el programa que supervisa todas las operaciones de backup, recuperaciones, verificaciones y almacenamiento (archive). El administrador de sistemas utiliza el Bacula Director para planificar los backups y recuperaciones de archivos. El Director corre como un demonio (o servicio) en según plan.
+ The Bacula Director service is the program that supervises
+ all the backup, restore, verify and archive operations. The system
+ administrator uses the Bacula Director to schedule backups and to
+ recover files. For more details see the Director Services Daemon Design
+ Document in the Bacula Developer's Guide. The Director runs as a daemon
+ (or service) in the background.
% TODO: tell reader where this Developer's Guide is at?
\label{UADef}
\subsection*{Bacula Console}
- El servicio de la consola de Bacula es el programa que permite a los administradores o usuarios comunicarse con el Bacula Director que esta en ejecución, y esta disponible en tres versiones: consola de texto (linea de comandos), interfaz GNOME y de interfaz gráfica wxWidgets. La primera, y la mas simple, consiste en correr el programa de consola (bconsole) en una ventana de comandos, por ejemplo, una interfaz TTY. La mayoría de los administradores encontraran que esta completamente adecuada para las tareas de admininistracion. La segunda versión es una basada en interfaz GNOME, que no están completa como la de texto, pero es funcional y permite realizar la mayoría de las tareas que la de comandos. La tercera versión es una GUI wxWidgets que permite restauración interactiva de archivos. También cuenta con muchas de las opciones de la consola de texto, permite la complementacion de comandos con tabuladores y ofrece ayuda en linea en relación al comando que se esta escribiendo. Para mayores informaciones vea la \ilink{Bacula Console Design Document}{_ConsoleChapter}.
+ The Bacula Console service is the program that allows the
+ administrator or user to communicate with the Bacula Director
+ Currently, the Bacula Console is available in three versions:
+ text-based console interface, GNOME-based interface, and a
+ wxWidgets graphical interface.
+ The first and simplest is to run the Console program in a shell window
+ (i.e. TTY interface). Most system administrators will find this
+ completely adequate. The second version is a GNOME GUI interface that
+ is far from complete, but quite functional as it has most the
+ capabilities of the shell Console. The third version is a wxWidgets GUI
+ with an interactive file restore. It also has most of the capabilities
+ of the shell console, allows command completion with tabulation, and
+ gives you instant help about the command you are typing. For more
+ details see the \ilink{Bacula Console Design Document}{_ConsoleChapter}.
\subsection*{Bacula File}
\label{FDDef}
- El servicio de Bacula file (también conocido como el programa cliente), es el software que se instala en el equipo al cual se le hará backup. Es especifico para cada sistema operativo en el cual corre y es el responsable por suministrar los atributos de archivos y los datos cuando sean requeridos por el Director. También es responsable por el file system en el cual se hace la restauración los atributos de archivos y datos durante una operación de restore. Este programa corre como un demonio o servicio en la maquina a la cual se le hace respaldo. En adición a los demonios de Unix y Linux, hay un demonio para Windows file (normalmente distribuido en formato de archivos binarios), y corre en las siguientes versiones de Windows (NT, XP, 2000, 2003, y posiblemente en Me y 98).
+ The Bacula File service (also known as the Client program) is the software
+ program that is installed on the machine to be backed up.
+ It is specific to the
+ operating system on which it runs and is responsible for providing the
+ file attributes and data when requested by the Director. The File
+ services are also responsible for the file system dependent part of
+ restoring the file attributes and data during a recovery operation. For
+ more details see the File Services Daemon Design Document in the Bacula
+ Developer's Guide. This program runs as a daemon on the machine to be
+ backed up.
+ In addition to Unix/Linux File daemons, there is a Windows File daemon
+ (normally distributed in binary format). The Windows File daemon runs
+ on current Windows versions (NT, 2000, XP, 2003, and possibly Me and
+ 98).
+% TODO: maybe do not list Windows here as that is listed elsewhere
+% TODO: remove "possibly"?
+% TODO: mention Vista?
\subsection*{Bacula Storage}
\label{SDDef}
- El servicio de Bacula storage consiste en el programa de software que realiza el almacenamiento y recuperación de los atributos de archivos y datos al medio físico de backup o volumen. En otras palabras, es el responsable por la lectura y escritura en los tapes (u otro media de almacenamiento, como archivos, DVD, USB, entre otros). El servicio de storage corre como un demonio en el equipo que tiene conectado y configurado el dispositivo de backup (generalmente, una unidad de cinta).
-
+ The Bacula Storage services consist of the software programs that
+ perform the storage and recovery of the file attributes and data to the
+ physical backup media or volumes. In other words, the Storage daemon is
+ responsible for reading and writing your tapes (or other storage media,
+ e.g. files). For more details see the Storage Services Daemon Design
+ Document in the Bacula Developer's Guide. The Storage services runs as
+ a daemon on the machine that has the backup device (usually a tape
+ drive).
% TODO: may switch e.g. to "for example" or "such as" as appropriate
% TODO: is "usually" correct? Maybe "such as" instead?
\subsection*{Catalog}
\label{DBDefinition}
- El servicio de catalogo comprende el programa de software responsable del mantenimiento de la base de datos de volúmenes y archivos índices para todos los archivos, a los cuales se les ha hecho respaldo. Permite a los administradores y usuarios, localizar rápidamente y recuperar cualquier objeto que se requiera. El catalogo distingue a Bacula de un programa de backup del sistema operativo, tales como tar, cpio o dump, porque mantiene un registro de todos los volúmenes utilizados, los jobs ejecutados y todos los archivos grabados, permitiendo, de esta manera, una restauración eficiente y administración de volúmenes. Bacula , actualmente, soporta tres tipos diferentes de bases de datos: MySQL, PostgrSQL y SQLite, el cual debe ser seleccionado cuando se instala el software.
-
- Las tres bases de datos soportadas actualmente, proveen un conjunto de funcionalidades, que incluyen indexamiento rápido, consultas arbitrarias y seguridad.

- Although the Bacula project plans to support other
+ The Catalog services are comprised of the software programs
+ responsible for maintaining the file indexes and volume databases for
+ all files backed up. The Catalog services permit the system
+ administrator or user to quickly locate and restore any desired file.
+ The Catalog services sets Bacula apart from simple backup programs like
+ tar and bru, because the catalog maintains a record of all Volumes used,
+ all Jobs run, and all Files saved, permitting efficient restoration and
+ Volume management. Bacula currently supports three different databases,
+ MySQL, PostgreSQL, and SQLite, one of which must be chosen when building
+ Bacula.
+
+ The three SQL databases currently supported (MySQL, PostgreSQL or
+ SQLite) provide quite a number of features, including rapid indexing,
+ arbitrary queries, and security. Although the Bacula project plans to support other
major SQL databases, the current Bacula implementation interfaces only
to MySQL, PostgreSQL and SQLite. For the technical and porting details
- see the Catalog Servicios Design Document in the developer's documented.
+ see the Catalog Services Design Document in the developer's documented.
The packages for MySQL and PostgreSQL are available for several operating
systems.
\subsection*{Bacula Monitor}
\label{MonDef}
- Es el servicio que permite a los administradores o usuarios observar el estado actual de los procesos de Bacula, tales como Director, file y storage. Actualmente, únicamente una versión en GTK+ esta disponible, la cual trabaja con GNOME, KDE o cualquier administrador de ventanas que soporte el sistema de bandeja estándar FreeDesktop.org.
-
- Para realizar una operación de respaldo y recuperación exitosa, los cuatro demonios siguientes deben estar configurados y en ejecución: el Director, el file, el storage y el catalogo (MySQL, PostgreSQL o SQLite).
+ A Bacula Monitor service is the program that allows the
+ administrator or user to watch current status of Bacula Directors,
+ Bacula File Daemons and Bacula Storage Daemons.
+ Currently, only a GTK+ version is available, which works with GNOME,
+ KDE, or any window manager that supports the FreeDesktop.org system tray
+ standard.
+ To perform a successful save or restore, the following four daemons must be
+ configured and running: the Director daemon, the File daemon, the Storage
+ daemon, and the Catalog service (MySQL, PostgreSQL or SQLite).

+\item [Administrator]
+ \index[fd]{Administrator }
+ The person or persons responsible for administrating the Bacula system.
\item [Backup]
\index[fd]{Backup }
- En Bacula, el termino backup se refiere a un Job que salva archivos
+ The term Backup refers to a Bacula Job that saves files.
\item [Bootstrap File]
\index[fd]{Bootstrap File }
- Es un archivo ASCII que contiene una forma compacta de comandos que permiten a Bacula o un utilitario de extracción de archivos stand-alone (bextract), restaurar el contenido de uno o mas volúmenes, por ejemplo, el estado actual de un sistema al cual se le hizo backup. Con un archivo Bootstrap, Bacula puede restaurar un sistema sin el catalogo. Se puede crear un archivo Bootstrap desde el catalogo para extraer cualquier archivo(s) que se desee(n).
-
-\item [Catalogo]
- \index[fd]{Catalogo }
- El catalogo es utilizado para almacenar información resumida de los Jobs, clientes y archivos a los cuales se les hace backup, así como en cual volumen o volúmenes La información registrada en el catalogo, permite a los usuarios y administradores determinar los Jobs se ejecutaron, así como su estado y las características importantes de los objetos respaldados, y lo mas importante, es un recurso fundamental durante las operaciones de restauración y recuperación El catalogo es un recurso online, pero no contiene los datos de los archivos respaldados. La mayor parte de la información almacenada en el catalogo, también es almacenada en los volúmenes de backup (como las cintas). De hecho, las cintas tendrán una copia de los datos del archivo, así como sus atributos particulares.
-
- El uso del catalogo, representa una de las características fundamentales de Bacula, que la distingue de los demás programas de backup y los comandos del sistema operativo, tales como tar o cpio.
-
-\item [Cliente]
- \index[fd]{Cliente }
- En términos de Bacula, la palabra cliente se refiere a la maquina a la cual se le esta haciendo backup, y es sinónimo para los servicios o demonios de file, y frecuentemente, se denota como FD. Un cliente, se define en un recurso en los archivos de configuración
-
-\item [Consola]
- \index[fd]{Consola }
- Es un programa de interfaz con el Director, que permite a los usuarios y administradores controlar los procesos de Bacula.
-
-\item [Demonio]
- \index[fd]{Demonio }
- En la terminología de UNIX, es un programa que esta en ejecución permanente en el background que permite llevar a cabo una tarea especifica. En los sistemas Windows, los demonios se denominan servicios.

-\item [Directiva]
- \index[fd]{Directiva }
- El termino Directiva, se utiliza para hacer referencia a una declaración o un registro dentro de un recurso en un archivo de configuración que indica una definición especifica. Por ejemplo, la directiva Name define el nombre de un Recurso.
+ The bootstrap file is an ASCII file containing a compact form of
+ commands that allow Bacula or the stand-alone file extraction utility
+ (bextract) to restore the contents of one or more Volumes, for
+ example, the current state of a system just backed up. With a bootstrap
+ file, Bacula can restore your system without a Catalog. You can create
+ a bootstrap file from a Catalog to extract any file or files you wish.
+
+\item [Catalog]
+ \index[fd]{Catalog }
+ The Catalog is used to store summary information about the Jobs,
+ Clients, and Files that were backed up and on what Volume or Volumes.
+ The information saved in the Catalog permits the administrator or user
+ to determine what jobs were run, their status as well as the important
+ characteristics of each file that was backed up, and most importantly,
+ it permits you to choose what files to restore.
+ The Catalog is an
+ online resource, but does not contain the data for the files backed up.
+ Most of the information stored in the catalog is also stored on the
+ backup volumes (i.e. tapes). Of course, the tapes will also have a
+ copy of the file data in addition to the File Attributes (see below).
+
+ The catalog feature is one part of Bacula that distinguishes it from
+ simple backup and archive programs such as dump and tar.
+
+\item [Client]
+ \index[fd]{Client }
+ In Bacula's terminology, the word Client refers to the machine being
+ backed up, and it is synonymous with the File services or File daemon,
+ and quite often, it is referred to it as the FD. A Client is defined in a
+ configuration file resource.
+
+\item [Console]
+ \index[fd]{Console }
+ The program that interfaces to the Director allowing the user or system
+ administrator to control Bacula.

+ systems, daemons are called Services.
+
+\item [Directive]
+ \index[fd]{Directive }
+ The term directive is used to refer to a statement or a record within a
+ Resource in a configuration file that defines one specific setting. For
+ example, the {\bf Name} directive defines the name of the Resource.
\item [Director]
\index[fd]{Director }
- El demonio principal de los servicios de Bacula que planifica y dirige todas las operaciones. Ocasionalmente, el proyecto se refiere al Director como DIR.
-
-\item [Diferencial]
- \index[fd]{Diferencial }
- Es un backup que incluye todos los archivos modificados desde la ejecución del ultimo respaldo de tipo completo (full). Hay que tener en cuenta que otros programas de respaldo, pueden definir este backup de manera diferente.
-
-\item [Atributos de Archivos]
- \index[fd]{Atributos de Archivos }
- Los atributos de archivos representan toda la información necesaria para identificar un archivo y todas sus propiedades, tales como tamaño, fecha de creación, permisos, entre otros. Generalmente, los atributos son manejados completamente por Bacula, por lo tanto el usuario no necesita conocer estos valores. Los atributos no incluyen los datos con la información de los archivos.
+ The main Bacula server daemon that schedules and directs all Bacula
+ operations. Occasionally, the project refers to the Director as DIR.
+
+\item [Differential]
+ \index[fd]{Differential }
+ A backup that includes all files changed since the last Full save started.
+ Note, other backup programs may define this differently.
+
+\item [File Attributes]
+ \index[fd]{File Attributes }
+ The File Attributes are all the information necessary about a file to
+ identify it and all its properties such as size, creation date, modification
+ date, permissions, etc. Normally, the attributes are handled entirely by
+ Bacula so that the user never needs to be concerned about them. The
+ attributes do not include the file's data.
\item [File Daemon]
\index[fd]{File Daemon }
- Se refiere al demonio que esta en ejecución en los computadores a los cuales se les hace backup. También se conoce como servicios de Archivo, y algunas veces como los servicios del cliente o FD.
+ The daemon running on the client computer to be backed up. This is also
+ referred to as the File services, and sometimes as the Client services or the
+ FD.
\label{FileSetDef}
\item [FileSet]
\index[fd]{a name }
- Un FileSet es un recurso definido en los archivos de configuración, que indica los archivos que serán respaldados. Este consiste de una lista de archivos o Directorios, una lista de archivos excluidos y como estos serán almacenados (compresión, encriptacion, firmas digitales). Para mayor informacion vea \ilink{FileSet Resource definition}{FileSetResource} in the Director chapter of this document.
+ A FileSet is a Resource contained in a configuration file that defines
+ the files to be backed up. It consists of a list of included files or
+ directories, a list of excluded files, and how the file is to be stored
+ (compression, encryption, signatures). For more details, see the
+ \ilink{FileSet Resource definition}{FileSetResource} in the Director
+ chapter of this document.
\item [Incremental]
\index[fd]{Incremental }
- Un backup que incluye todos los archivos modificados desde el ultimo respaldo full, differential o incremental ejecutado. Normalmente, se define con la directiva {\bf Level} dentro de la configuración del recurso Job, o en el recurso de Schedule.
+ A backup that includes all files changed since the last Full, Differential,
+ or Incremental backup started. It is normally specified on the {\bf Level}
+ directive within the Job resource definition, or in a Schedule resource.
\label{JobDef}
\item [Job]
\index[fd]{a name }
- Un Job es un recurso de configuración que define el trabajo que Bacula debe realizar para ejecutar un backup o un restore para un cliente particular. Esto consiste en el {\bf Tipo} (backup, restore, verificar, etc), el {\bf Nivel} (full, incremental,...), el {\bf FileSet} y el {\bf Storage}, para los archivos a los cuales se les hará backup (dispositivo de almacenamientos, medias para el pool). Para mayores detalles, vea the \ilink{Job Resource definition}{JobResource} in the Director chapter of this document.
+ A Bacula Job is a configuration resource that defines the work that
+ Bacula must perform to backup or restore a particular Client. It
+ consists of the {\bf Type} (backup, restore, verify, etc), the {\bf
+ Level} (full, incremental,...), the {\bf FileSet}, and {\bf Storage} the
+ files are to be backed up (Storage device, Media Pool). For more
+ details, see the \ilink{Job Resource definition}{JobResource} in the
+ Director chapter of this document.

\index[fd]{Monitor }
- Es un programa que interactúa con todos los demonios y permite al usuario o administrador monitorizar el estado de Bacula.
+ The program that interfaces to all the daemons allowing the user or
+ system administrator to monitor Bacula status.
\item [Resource]
\index[fd]{Resource }
- Un recurso es una parte de un archivo de configuración que define una unidad especifica de información que esta disponible en Bacula. Consiste de varias directivas (declaraciones individuales de configuración). Por ejemplo, el recurso {\bf Job} define todas las propiedades especificas de un Job: nombre, schedule, volumen del pool, tipo de backup, nivel de backup, entre otros.
+ A resource is a part of a configuration file that defines a specific
+ unit of information that is available to Bacula. It consists of several
+ directives (individual configuration statements). For example, the {\bf
+ Job} resource defines all the properties of a specific Job: name,
+ schedule, Volume pool, backup type, backup level, ...
+% TODO: clean up "..." for book
\item [Restore]
\index[fd]{Restore }
- Es un recurso de configuración que describe la operación de recuperación de un archivo desde un medio de backup. Es lo contrario a salvar, excepto que en la mayoría de los casos, una restauración (restore) normalmente tendrá un numero pequeño de archivos a recuperar, mientras que un backup, abarca todos los archivos en un sistema. De hecho, después de una falla de disco, se puede utilizar a Bacula para realizar una restauración completa de todos los archivos que en encontraban en el equipo.
+ A restore is a configuration resource that describes the operation of
+ recovering a file from backup media. It is the inverse of a save,
+ except that in most cases, a restore will normally have a small set of
+ files to restore, while normally a Save backs up all the files on the
+ system. Of course, after a disk crash, Bacula can be called upon to do
+ a full Restore of all files that were on the system.
% TODO: Why? Why say "Of course"??
% TODO: define "Save"
\item [Schedule]
\index[fd]{Schedule }
- Es un recurso de configuración que define cuando un Job de Bacula tiene planificada su ejecución Para utilizar el schedule, en el recurso de Job se hace referencia al nombre del schedule. Para mayores detalles, vea \ilink{Schedule Resource definition}{ScheduleResource} in the Director chapter of this document.
-
-\item [Servicio]
- \index[fd]{Servicio }
- Es un programa que permanece de manera permanente en memoria esperando instrucciones. En entornos UNIX, los servicios se conocen como {\bf demonios}.
-
-\item [Almacenamiento de Coordenadas]
- \index[fd]{Almacenamiento de Coordenadas }
- La información retornada desde los servicios de almacenamiento que localiza de manera única un archivo en un dispositivo de backup. Consiste de dos partes: una parte contiene cada archivo grabado y la otra contiene el Job completo. Normalmente, esta información es salvada en el catalogo, por lo tanto el usuario no necesita tener conocimiento especifico de estas coordenadas. Adicionalmente, incluyen los atributos de archivos (ver abajo) as la ubicación única de la información en el volumen de respaldo.
+ A Schedule is a configuration resource that defines when the Bacula Job
+ will be scheduled for execution. To use the Schedule, the Job resource
+ will refer to the name of the Schedule. For more details, see the
+ \ilink{Schedule Resource definition}{ScheduleResource} in the Director
+ chapter of this document.
+
+\item [Service]
+ \index[fd]{Service }
+ This is a program that remains permanently in memory awaiting
+ instructions. In Unix environments, services are also known as
+ {\bf daemons}.
+
+\item [Storage Coordinates]
+ \index[fd]{Storage Coordinates }
+ The information returned from the Storage Services that uniquely locates
+ a file on a backup medium. It consists of two parts: one part pertains
+ to each file saved, and the other part pertains to the whole Job.
+ Normally, this information is saved in the Catalog so that the user
+ doesn't need specific knowledge of the Storage Coordinates. The Storage
+ Coordinates include the File Attributes (see above) plus the unique
+ location of the information on the backup Volume.
\item [Storage Daemon]
\index[fd]{Storage Daemon }
- Algunas veces se refiere como el SD, y es el código que escribe los atributos y data al volumen de almacenamiento (generalmente, disco o cinta).
-
-\item [Sesión]
- \index[sd]{Sesión }
- Generalmente, se refiere a la conversación interna entre el demonio del cliente y el demonio de almacenamiento. El demonio del cliente abre una {\bf sesión} con el demonio de almacenamiento para grabar un FileSet o para restaurarlo. Una sesión tiene una correspondencia uno a uno con un Job de Bacula.
-
-\item [Verificar]
- \index[sd]{Verificar }
- Es un Job que compara los atributos actuales de un archivo con los atributos que han sido previamente almacenados en el catalogo. Esta funcionalidad puede ser utilizada para la detección de cambios a archivos críticos del sistema, de manera similar a un chequeo de integridad. Una de las mayores ventajas del uso de Bacula para esta actividad, es que en el equipo que se quiere proteger, únicamente corre el servicio de archivo (file daemon), y el Director, storage daemon y el catalogo residen en una maquina diferente.
-
-También puede ser utilizado para chequear que la data del Job mas reciente escrito en el volumen, coincida con lo que esta almacenado en el catalogo (es decir, compara los atributos de los archivos), o puede chequear el contenido del volumen contra los archivos originales en disco.
-
-\item [*Archivar]
- \index[fd]{*Archivar }
- Una operación de archivado (archive), se realiza después del grabado, y consiste en la remoción de los volúmenes en los cuales la data fue almacenada de las operaciones de respaldo. Los volúmenes son marcados como Archivados, y ya no pueden ser usados para grabar archivos. Todos los archivos contenidos en un volumen con estado Archivado son removidos del catalogo. Todavía no esta implementado.
-
-\item [Periodo de Retención]
- \index[fd]{Periodo de Retención }
-Hay varios modos de periodos de retención que Bacula reconoce. Los mas importantes son periodo de retención de {\bf archivos} (file retention), periodo de retención de {\bf Jobs} (Job retention) y periodo de retención de {\bf volúmenes} (volume retention). Cada uno de estos periodos de retención aplican al tiempo que los registros específicos se mantendrán en la base de datos del catalogo. Esto no debe ser confundido con el tiempo para el cual la data grabada en el volumen es considerada valida.
-
-El periodo de retención de archivos determina el tiempo que los registros de archivos se mantendrán en el catalogo. Este periodo es importante por dos razones: la primera, es que el tiempo que los registros permanezcan en la base de datos, se puede “navegar” en estos archivos con un programa de consola, y hacer restauraciones individuales. Una vez que los registros son removidos (pruned) del catalogo, los archivos individuales de un Job de respaldo no pueden ser visualizados en modo de “navegación”.
-
-La segunda razón para seleccionar este periodo de manera cuidadosa, es que estos registros ocupan la mayor parte del almacenamiento en la base de datos. Por esto, se debe asegurar que el “pruning” regular de los registros de archivos en el catalogo se ejecute, para evitar el crecimiento excesivo del mismo. (See the Console {\bf prune} command for more details on this subject).
-
-El periodo de retención de jobs, es el tiempo que los registros de los jobs permanecerán en el catalogo. Hay que tener presente, que los registros de archivos están unidos al Job que los grabo. Los registros de archivos pueden ser purgados dejando los registros de jobs. Es este caso, la información que estará disponible es la de los jobs ejecutados, y no los detalles de los archivos respaldados. Generalmente, cuando los jobs son purgados, todos los registros de archivos también serán purgados.
-
-El periodo de retención de volumen, representa el mínimo de tiempo que un volumen sera mantenido antes que sea reutilizado. Bacula, en condiciones normales, nunca sobreescribe un volumen que contenga la única copia del backup de un archivo. Bajo condiciones ideales, el catalogo retendría las entradas para todos los archivos respaldados para todos los volúmenes Una vez que un volumen es sobreescrito, los archivos que contenía este volumen son removidos automáticamente del catalogo. Sin embargo, si hay un gran numero de volúmenes para un pool o si un volumen nunca es reutilizado, la base de datos del catalogo puede llegar a ser enorme. Para mantener el catalogo con un tamaño manejable, la información del backup debería ser removida de la base de datos después del periodo de retención de archivos. Bacula suministra los mecanismos para que el “pruning” se haga de manera automática, de acuerdo a los periodos de retención definidos.
-
+ The Storage daemon, sometimes referred to as the SD, is the code that
+ writes the attributes and data to a storage Volume (usually a tape or
+ disk).
+
+\item [Session]
+ \index[sd]{Session }
+ Normally refers to the internal conversation between the File daemon and
+ the Storage daemon. The File daemon opens a {\bf session} with the
+ Storage daemon to save a FileSet or to restore it. A session has a
+ one-to-one correspondence to a Bacula Job (see above).
+
+\item [Verify]
+ \index[sd]{Verify }
+ A verify is a job that compares the current file attributes to the
+ attributes that have previously been stored in the Bacula Catalog. This
+ feature can be used for detecting changes to critical system files
+ similar to what a file integrity checker like Tripwire does.
+ One of the major advantages of
+ using Bacula to do this is that on the machine you want protected such
+ as a server, you can run just the File daemon, and the Director, Storage
+ daemon, and Catalog reside on a different machine. As a consequence, if
+ your server is ever compromised, it is unlikely that your verification
+ database will be tampered with.
+
+ Verify can also be used to check that the most recent Job data written
+ to a Volume agrees with what is stored in the Catalog (i.e. it compares
+ the file attributes), *or it can check the Volume contents against the
+ original files on disk.
+
+\item [*Archive]
+ \index[fd]{*Archive }
+ An Archive operation is done after a Save, and it consists of removing the
+ Volumes on which data is saved from active use. These Volumes are marked as
+ Archived, and may no longer be used to save files. All the files contained
+ on an Archived Volume are removed from the Catalog. NOT YET IMPLEMENTED.
+
+\item [Retention Period]
+ \index[fd]{Retention Period }
+ There are various kinds of retention periods that Bacula recognizes.
+ The most important are the {\bf File} Retention Period, {\bf Job}
+ Retention Period, and the {\bf Volume} Retention Period. Each of these
+ retention periods applies to the time that specific records will be kept
+ in the Catalog database. This should not be confused with the time that
+ the data saved to a Volume is valid.
+
+ The File Retention Period determines the time that File records are kept
+ in the catalog database. This period is important for two reasons: the
+ first is that as long as File records remain in the database, you
+ can "browse" the database with a console program and restore any
+ individual file. Once the File records are removed or pruned from the
+ database, the individual files of a backup job can no longer be
+ "browsed". The second reason for carefully choosing the File Retention
+ Period is because the volume of
+ the database File records use the most storage space in the
+ database. As a consequence, you must ensure that regular "pruning" of
+ the database file records is done to keep your database from growing
+ too large. (See the Console {\bf prune}
+ command for more details on this subject).
+
+ The Job Retention Period is the length of time that Job records will be
+ kept in the database. Note, all the File records are tied to the Job
+ that saved those files. The File records can be purged leaving the Job
+ records. In this case, information will be available about the jobs
+ that ran, but not the details of the files that were backed up.
+ Normally, when a Job record is purged, all its File records will also be
+ purged.
+
+ The Volume Retention Period is the minimum of time that a Volume will be
+ kept before it is reused. Bacula will normally never overwrite a Volume
+ that contains the only backup copy of a file. Under ideal conditions,
+ the Catalog would retain entries for all files backed up for all current
+ Volumes. Once a Volume is overwritten, the files that were backed up on
+ that Volume are automatically removed from the Catalog. However, if
+ there is a very large pool of Volumes or a Volume is never overwritten,
+ the Catalog database may become enormous. To keep the Catalog to a
+ manageable size, the backup information should be removed from the
+ Catalog after the defined File Retention Period. Bacula provides the
+ mechanisms for the catalog to be automatically pruned according to the
+ retention periods defined.
\item [Scan]
\index[sd]{Scan }
- Una operación de “scan”, provoca que el contenido de un volumen o un conjunto de volúmenes, sean explorados (“escaneados”). Estos volúmenes y la información de los archivos que contienen, son restauradas al catalogo. Una vez que la información esta en el catalogo, los archivos grabados en estos volúmenes puede ser restaurados fácilmente Esta operación es particularmente útil cuando algunos volúmenes o jobs han excedido sus periodos de retención y han sido eliminados del catalogo. El escaneo de la data de los volúmenes al catalogo, se hace utilizando el programa {\bf bscan}. See the \ilink{ bscan section}{bscan} of the Bacula Utilities Chapter of this manual for more details.
+ A Scan operation causes the contents of a Volume or a series of Volumes
+ to be scanned. These Volumes with the information on which files they
+ contain are restored to the Bacula Catalog. Once the information is
+ restored to the Catalog, the files contained on those Volumes may be
+ easily restored. This function is particularly useful if certain
+ Volumes or Jobs have exceeded their retention period and have been
+ pruned or purged from the Catalog. Scanning data from Volumes into the
+ Catalog is done by using the {\bf bscan} program. See the \ilink{ bscan
+ section}{bscan} of the Bacula Utilities Chapter of this manual for more
+ details.
\item [Volume]
\index[sd]{Volume }
- Es una unidad de archivo, generalmente una cinta o un archivo en disco donde Bacula almacena la data de uno o mas jobs de respaldo. Todos los volúmenes tienen una etiqueta de software escrita al volumen por Bacula, para que se pueda identificar cual volumen se esta utilizando realmente (normalmente, con habrá confusión con los archivos de disco, pero con las cintas, es muy fácil montar uno equivocado).
-
+ A Volume is an archive unit, normally a tape or a named disk file where
+ Bacula stores the data from one or more backup jobs. All Bacula Volumes
+ have a software label written to the Volume by Bacula so that it
+ identifies what Volume it is really reading. (Normally there should be
+ no confusion with disk files, but with tapes, it is easy to mount the
+ wrong one.)

-\section{Que No es Bacula}
-\index[general]{Que No es Bacula}
-
-Bacula es una aplicación de backup, restauración y verificación y no un sistema completo de disaster recovery en si mismo, sin embargo, puede ser una parte fundamental del mismo y siga las instrucciones incluidas en el \ilink{ Disaster Recovery}{RescueChapter} Chapter of this manual.
-
-Con una planificación apropiada, Bacula puede llegar a ser uno de los componentes centrales del sistema de disaster recovery. Por ejemplo, si se ha creado un disco de arranque de emergencia y/o un disco de rescate de Bacula para almacenar la información del particionamiento actual del disco duro, y se cuenta con un backup completo, es posible recuperar el sistema totalmente, partiendo desde un disco vacío (“bare metal”).
+\section{What Bacula is Not}
+\index[general]{What Bacula is Not}
-Si se ha utilizado el registro de {\bf WriteBootstrap} en los jobs o algún otro medio para grabar un archivo Bootstrap valido, se puede hacer uso de este para extraer los archivos que sean necesarios (sin el uso del catalogo o realizando búsquedas manuales de los archivos a restaurar).
+Bacula is a backup, restore and verification program and is not a
+complete disaster recovery system in itself, but it can be a key part of one
+if you plan carefully and follow the instructions included in the
+\ilink{ Disaster Recovery}{RescueChapter} Chapter of this manual.
+With proper planning, as mentioned in the Disaster Recovery chapter,
+Bacula can be a central component of your disaster recovery system. For
+example, if you have created an emergency boot disk, and/or a Bacula Rescue disk to
+save the current partitioning information of your hard disk, and maintain a
+complete Bacula backup, it is possible to completely recover your system from
+"bare metal" that is starting from an empty disk.
+If you have used the {\bf WriteBootstrap} record in your job or some other
+means to save a valid bootstrap file, you will be able to use it to extract
+the necessary files (without using the catalog or manually searching for the
+files to restore).

+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.

+\section{Preamble}
+\label{SEC2}
+\index[general]{Preamble }
+
+The licenses for most software are designed to take away your freedom to share
+and change it. By contrast, the GNU General Public License is intended to
+guarantee your freedom to share and change free software\verb:--:to make sure the
+software is free for all its users. This General Public License applies to
+most of the Free Software Foundation's software and to any other program whose
+authors commit to using it. (Some other Free Software Foundation software is
+covered by the GNU Library General Public License instead.) You can apply it
+to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom to
+distribute copies of free software (and charge for this service if you wish),
+that you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs; and that you know you
+can do these things.
+
+To protect your rights, we need to make restrictions that forbid anyone to
+deny you these rights or to ask you to surrender the rights. These
+restrictions translate to certain responsibilities for you if you distribute
+copies of the software, or if you modify it.
+
+For example, if you distribute copies of such a program, whether gratis or for
+a fee, you must give the recipients all the rights that you have. You must
+make sure that they, too, receive or can get the source code. And you must
+show them these terms so they know their rights.
+
+We protect your rights with two steps: (1) copyright the software, and (2)
+offer you this license which gives you legal permission to copy, distribute
+and/or modify the software.
+
+Also, for each author's protection and ours, we want to make certain that
+everyone understands that there is no warranty for this free software. If the
+software is modified by someone else and passed on, we want its recipients to
+know that what they have is not the original, so that any problems introduced
+by others will not reflect on the original authors' reputations.
+
+Finally, any free program is threatened constantly by software patents. We
+wish to avoid the danger that redistributors of a free program will
+individually obtain patent licenses, in effect making the program proprietary.
+To prevent this, we have made it clear that any patent must be licensed for
+everyone's free use or not licensed at all.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+\section{TERMS AND CONDITIONS}
+\label{SEC3}
+\index[general]{CONDITIONS!TERMS AND }
+\index[general]{TERMS AND CONDITIONS }
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+{\bf 0.} This License applies to any program or other work which contains a
+notice placed by the copyright holder saying it may be distributed under the
+terms of this General Public License. The "Program", below, refers to any
+such program or work, and a "work based on the Program" means either the
+Program or any derivative work under copyright law: that is to say, a work
+containing the Program or a portion of it, either verbatim or with
+modifications and/or translated into another language. (Hereinafter,
+translation is included without limitation in the term "modification".) Each
+licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not covered
+by this License; they are outside its scope. The act of running the Program is
+not restricted, and the output from the Program is covered only if its
+contents constitute a work based on the Program (independent of having been
+made by running the Program). Whether that is true depends on what the Program
+does.
+
+{\bf 1.} You may copy and distribute verbatim copies of the Program's source
+code as you receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice and
+disclaimer of warranty; keep intact all the notices that refer to this License
+and to the absence of any warranty; and give any other recipients of the
+Program a copy of this License along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and you may
+at your option offer warranty protection in exchange for a fee.
+
+{\bf 2.} You may modify your copy or copies of the Program or any portion of
+it, thus forming a work based on the Program, and copy and distribute such
+modifications or work under the terms of Section 1 above, provided that you
+also meet all of these conditions:
+
+\begin{itemize}
+\item {\bf a)} You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+\item {\bf b)} You must cause any work that you distribute or publish, that
+ in whole or in part contains or is derived from the Program or any part
+ thereof, to be licensed as a whole at no charge to all third parties under
+ the terms of this License.
+
+\item {\bf c)} If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such interactive use in
+ the most ordinary way, to print or display an announcement including an
+ appropriate copyright notice and a notice that there is no warranty (or else,
+ saying that you provide a warranty) and that users may redistribute the
+ program under these conditions, and telling the user how to view a copy of
+ this License. (Exception: if the Program itself is interactive but does not
+ normally print such an announcement, your work based on the Program is not
+ required to print an announcement.)
+\end{itemize}
+
+These requirements apply to the modified work as a whole. If identifiable
+sections of that work are not derived from the Program, and can be reasonably
+considered independent and separate works in themselves, then this License,
+and its terms, do not apply to those sections when you distribute them as
+separate works. But when you distribute the same sections as part of a whole
+which is a work based on the Program, the distribution of the whole must be on
+the terms of this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest your
+rights to work written entirely by you; rather, the intent is to exercise the
+right to control the distribution of derivative or collective works based on
+the Program.
+
+In addition, mere aggregation of another work not based on the Program with
+the Program (or with a work based on the Program) on a volume of a storage or
+distribution medium does not bring the other work under the scope of this
+License.
+
+{\bf 3.} You may copy and distribute the Program (or a work based on it, under
+Section 2) in object code or executable form under the terms of Sections 1 and
+2 above provided that you also do one of the following:
+
+\begin{itemize}
+\item {\bf a)} Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections 1 and 2
+ above on a medium customarily used for software interchange; or,
+
+\item {\bf b)} Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your cost of
+ physically performing source distribution, a complete machine-readable copy of
+ the corresponding source code, to be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+\item {\bf c)} Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is allowed only
+ for noncommercial distribution and only if you received the program in object
+ code or executable form with such an offer, in accord with Subsection b
+ above.)
+\end{itemize}
+
+The source code for a work means the preferred form of the work for making
+modifications to it. For an executable work, complete source code means all
+the source code for all modules it contains, plus any associated interface
+definition files, plus the scripts used to control compilation and
+installation of the executable. However, as a special exception, the source
+code distributed need not include anything that is normally distributed (in
+either source or binary form) with the major components (compiler, kernel, and
+so on) of the operating system on which the executable runs, unless that
+component itself accompanies the executable.
+
+If distribution of executable or object code is made by offering access to
+copy from a designated place, then offering equivalent access to copy the
+source code from the same place counts as distribution of the source code,
+even though third parties are not compelled to copy the source along with the
+object code.
+
+{\bf 4.} You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt otherwise to
+copy, modify, sublicense or distribute the Program is void, and will
+automatically terminate your rights under this License. However, parties who
+have received copies, or rights, from you under this License will not have
+their licenses terminated so long as such parties remain in full compliance.
+
+{\bf 5.} You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or distribute
+the Program or its derivative works. These actions are prohibited by law if
+you do not accept this License. Therefore, by modifying or distributing the
+Program (or any work based on the Program), you indicate your acceptance of
+this License to do so, and all its terms and conditions for copying,
+distributing or modifying the Program or works based on it.
+
+{\bf 6.} Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the original
+licensor to copy, distribute or modify the Program subject to these terms and
+conditions. You may not impose any further restrictions on the recipients'
+exercise of the rights granted herein. You are not responsible for enforcing
+compliance by third parties to this License.
+
+{\bf 7.} If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or otherwise)
+that contradict the conditions of this License, they do not excuse you from
+the conditions of this License. If you cannot distribute so as to satisfy
+simultaneously your obligations under this License and any other pertinent
+obligations, then as a consequence you may not distribute the Program at all.
+For example, if a patent license would not permit royalty-free redistribution
+of the Program by all those who receive copies directly or indirectly through
+you, then the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply and
+the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any patents or
+other property right claims or to contest validity of any such claims; this
+section has the sole purpose of protecting the integrity of the free software
+distribution system, which is implemented by public license practices. Many
+people have made generous contributions to the wide range of software
+distributed through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing to
+distribute software through any other system and a licensee cannot impose that
+choice.
+
+This section is intended to make thoroughly clear what is believed to be a
+consequence of the rest of this License.
+
+{\bf 8.} If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the original
+copyright holder who places the Program under this License may add an explicit
+geographical distribution limitation excluding those countries, so that
+distribution is permitted only in or among countries not thus excluded. In
+such case, this License incorporates the limitation as if written in the body
+of this License.
+
+{\bf 9.} The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will be
+similar in spirit to the present version, but may differ in detail to address
+new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any later
+version", you have the option of following the terms and conditions either of
+that version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of this License,
+you may choose any version ever published by the Free Software Foundation.
+
+{\bf 10.} If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author to
+ask for permission. For software which is copyrighted by the Free Software
+Foundation, write to the Free Software Foundation; we sometimes make
+exceptions for this. Our decision will be guided by the two goals of
+preserving the free status of all derivatives of our free software and of
+promoting the sharing and reuse of software generally.
+
+{\bf NO WARRANTY}
+
+{\bf 11.} BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE
+THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR
+IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO
+THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
+PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+{\bf 12.} IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO
+LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR
+THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+END OF TERMS AND CONDITIONS

+\section{How to Apply These Terms to Your New Programs}
+\label{SEC4}
+\index[general]{Programs!How to Apply These Terms to Your New }
+\index[general]{How to Apply These Terms to Your New Programs }
+
+If you develop a new program, and you want it to be of the greatest possible
+use to the public, the best way to achieve this is to make it free software
+which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach
+them to the start of each source file to most effectively convey the exclusion
+of warranty; and each file should have at least the "copyright" line and a
+pointer to where the full notice is found.
+
+\footnotesize
+\begin{verbatim}
+{\em one line to give the program's name and an idea of what it does.}
+Copyright (C) {\em yyyy} {\em name of author}
+This program is free software; you can redistribute it and/or
+modify it under the terms of the GNU General Public License
+as published by the Free Software Foundation; either version 2
+of the License, or (at your option) any later version.
+This program is distributed in the hope that it will be useful,
+but WITHOUT ANY WARRANTY; without even the implied warranty of
+MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+GNU General Public License for more details.
+You should have received a copy of the GNU General Public License
+along with this program; if not, write to the Free Software
+Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA
+02110-1301 USA
+\end{verbatim}
+\normalsize
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this when it
+starts in an interactive mode:
+
+\footnotesize
+\begin{verbatim}
+Gnomovision version 69, Copyright (C) {\em year} {\em name of author}
+Gnomovision comes with ABSOLUTELY NO WARRANTY; for details
+type `show w'. This is free software, and you are welcome
+to redistribute it under certain conditions; type `show c'
+for details.
+\end{verbatim}
+\normalsize
+
+The hypothetical commands {\tt `show w'} and {\tt `show c'} should show the
+appropriate parts of the General Public License. Of course, the commands you
+use may be called something other than {\tt `show w'} and {\tt `show c'}; they
+could even be mouse-clicks or menu items\verb:--:whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+\footnotesize
+\begin{verbatim}
+Yoyodyne, Inc., hereby disclaims all copyright
+interest in the program `Gnomovision'
+(which makes passes at compilers) written
+by James Hacker.
+{\em signature of Ty Coon}, 1 April 1989
+Ty Coon, President of Vice
+\end{verbatim}
+\normalsize
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General Public
+License instead of this License.

+# ___________________
+#
+# For the multiple-index style, each index is identified by the ref argument to \newindex, \index,
+# and \printindex. A default index is allowed, which is indicated by omitting the optional
+# argument. The default index does not require a \newindex command. As \index commands
+# are encountered, their entries are stored according
+# to the ref argument. When the \printindex command is encountered, the stored index
+# entries for that argument are retrieved and printed. The title for each index is taken
+# from the last argument in the \newindex command.
+# While processing \index and \printindex commands, if no argument is given the index entries
+# are built into a default index. The title of the default index is simply "Index".
+# This makes the difference between single- and multiple-index processing trivial.
+#
+# Another method can be used by omitting the \printindex command and just using \include to
+# pull in index files created by the makeindex program. These files will start with
+# \begin{theindex}. This command is used to determine where to print the index. Using this
+# approach, the indices will be output in the same order as the newindex commands were
+# originally found (see below). Using a combination of \printindex and \include{indexfile} has not
+# been tested and may produce undesireable results.
+#
+# The index data are stored in a hash for later sorting and output. As \printindex
+# commands are handled, the order in which they were found in the tex filea is saved,
+# associated with the ref argument to \printindex.
+#
+# We use the original %index hash to store the index data into. We append a \002 followed by the
+# name of the index to isolate the entries in different indices from each other. This is necessary
+# so that different indices can have entries with the same name. For the default index, the \002 is
+# appended without the name.
+#

+\section{Preamble}
+\label{SEC23}
+\index[general]{Preamble }
+
+The licenses for most software are designed to take away your freedom to share
+and change it. By contrast, the GNU General Public Licenses are intended to
+guarantee your freedom to share and change free software\verb:--:to make sure the
+software is free for all its users.
+
+This license, the Lesser General Public License, applies to some specially
+designated software packages\verb:--:typically libraries\verb:--:of the Free Software
+Foundation and other authors who decide to use it. You can use it too, but we
+suggest you first think carefully about whether this license or the ordinary
+General Public License is the better strategy to use in any particular case,
+based on the explanations below.
+
+When we speak of free software, we are referring to freedom of use, not price.
+Our General Public Licenses are designed to make sure that you have the
+freedom to distribute copies of free software (and charge for this service if
+you wish); that you receive source code or can get it if you want it; that you
+can change the software and use pieces of it in new free programs; and that
+you are informed that you can do these things.
+
+To protect your rights, we need to make restrictions that forbid distributors
+to deny you these rights or to ask you to surrender these rights. These
+restrictions translate to certain responsibilities for you if you distribute
+copies of the library or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or for a
+fee, you must give the recipients all the rights that we gave you. You must
+make sure that they, too, receive or can get the source code. If you link
+other code with the library, you must provide complete object files to the
+recipients, so that they can relink them with the library after making changes
+to the library and recompiling it. And you must show them these terms so they
+know their rights.
+
+We protect your rights with a two-step method: (1) we copyright the library,
+and (2) we offer you this license, which gives you legal permission to copy,
+distribute and/or modify the library.
+
+To protect each distributor, we want to make it very clear that there is no
+warranty for the free library. Also, if the library is modified by someone
+else and passed on, the recipients should know that what they have is not the
+original version, so that the original author's reputation will not be
+affected by problems that might be introduced by others.
+
+Finally, software patents pose a constant threat to the existence of any free
+program. We wish to make sure that a company cannot effectively restrict the
+users of a free program by obtaining a restrictive license from a patent
+holder. Therefore, we insist that any patent license obtained for a version of
+the library must be consistent with the full freedom of use specified in this
+license.
+
+Most GNU software, including some libraries, is covered by the ordinary GNU
+General Public License. This license, the GNU Lesser General Public License,
+applies to certain designated libraries, and is quite different from the
+ordinary General Public License. We use this license for certain libraries in
+order to permit linking those libraries into non-free programs.
+
+When a program is linked with a library, whether statically or using a shared
+library, the combination of the two is legally speaking a combined work, a
+derivative of the original library. The ordinary General Public License
+therefore permits such linking only if the entire combination fits its
+criteria of freedom. The Lesser General Public License permits more lax
+criteria for linking other code with the library.
+
+We call this license the "Lesser" General Public License because it does
+Less to protect the user's freedom than the ordinary General Public License.
+It also provides other free software developers Less of an advantage over
+competing non-free programs. These disadvantages are the reason we use the
+ordinary General Public License for many libraries. However, the Lesser
+license provides advantages in certain special circumstances.
+
+For example, on rare occasions, there may be a special need to encourage the
+widest possible use of a certain library, so that it becomes a de-facto
+standard. To achieve this, non-free programs must be allowed to use the
+library. A more frequent case is that a free library does the same job as
+widely used non-free libraries. In this case, there is little to gain by
+limiting the free library to free software only, so we use the Lesser General
+Public License.
+
+In other cases, permission to use a particular library in non-free programs
+enables a greater number of people to use a large body of free software. For
+example, permission to use the GNU C Library in non-free programs enables many
+more people to use the whole GNU operating system, as well as its variant, the
+GNU/Linux operating system.
+
+Although the Lesser General Public License is Less protective of the users'
+freedom, it does ensure that the user of a program that is linked with the
+Library has the freedom and the wherewithal to run that program using a
+modified version of the Library.
+
+The precise terms and conditions for copying, distribution and modification
+follow. Pay close attention to the difference between a "work based on the
+library" and a "work that uses the library". The former contains code
+derived from the library, whereas the latter must be combined with the library
+in order to run.
+
+\section{TERMS AND CONDITIONS}
+\label{SEC34}
+\index[general]{CONDITIONS!TERMS AND }
+\index[general]{TERMS AND CONDITIONS }
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+{\bf 0.} This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or other
+authorized party saying it may be distributed under the terms of this Lesser
+General Public License (also called "this License"). Each licensee is
+addressed as "you".
+
+A "library" means a collection of software functions and/or data prepared so
+as to be conveniently linked with application programs (which use some of
+those functions and data) to form executables.
+
+The "Library", below, refers to any such software library or work which has
+been distributed under these terms. A "work based on the Library" means
+either the Library or any derivative work under copyright law: that is to say,
+a work containing the Library or a portion of it, either verbatim or with
+modifications and/or translated straightforwardly into another language.
+(Hereinafter, translation is included without limitation in the term
+"modification".)
+
+"Source code" for a work means the preferred form of the work for making
+modifications to it. For a library, complete source code means all the source
+code for all modules it contains, plus any associated interface definition
+files, plus the scripts used to control compilation and installation of the
+library.
+
+Activities other than copying, distribution and modification are not covered
+by this License; they are outside its scope. The act of running a program
+using the Library is not restricted, and output from such a program is covered
+only if its contents constitute a work based on the Library (independent of
+the use of the Library in a tool for writing it). Whether that is true depends
+on what the Library does and what the program that uses the Library does.
+
+{\bf 1.} You may copy and distribute verbatim copies of the Library's complete
+source code as you receive it, in any medium, provided that you conspicuously
+and appropriately publish on each copy an appropriate copyright notice and
+disclaimer of warranty; keep intact all the notices that refer to this License
+and to the absence of any warranty; and distribute a copy of this License
+along with the Library.
+
+You may charge a fee for the physical act of transferring a copy, and you may
+at your option offer warranty protection in exchange for a fee.
+
+{\bf 2.} You may modify your copy or copies of the Library or any portion of
+it, thus forming a work based on the Library, and copy and distribute such
+modifications or work under the terms of Section 1 above, provided that you
+also meet all of these conditions:
+
+\begin{itemize}
+\item {\bf a)} The modified work must itself be a software library.
+\item {\bf b)} You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+\item {\bf c)} You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+\item {\bf d)} If a facility in the modified Library refers to a function or
+ a table of data to be supplied by an application program that uses the
+ facility, other than as an argument passed when the facility is invoked, then
+you must make a good faith effort to ensure that, in the event an application
+does not supply such function or table, the facility still operates, and
+performs whatever part of its purpose remains meaningful.
+
+(For example, a function in a library to compute square roots has a purpose
+that is entirely well-defined independent of the application. Therefore,
+Subsection 2d requires that any application-supplied function or table used
+by this function must be optional: if the application does not supply it, the
+square root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If identifiable
+sections of that work are not derived from the Library, and can be reasonably
+considered independent and separate works in themselves, then this License,
+and its terms, do not apply to those sections when you distribute them as
+separate works. But when you distribute the same sections as part of a whole
+which is a work based on the Library, the distribution of the whole must be
+on the terms of this License, whose permissions for other licensees extend to
+the entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest your
+rights to work written entirely by you; rather, the intent is to exercise the
+right to control the distribution of derivative or collective works based on
+the Library.
+
+In addition, mere aggregation of another work not based on the Library with
+the Library (or with a work based on the Library) on a volume of a storage or
+distribution medium does not bring the other work under the scope of this
+License.
+\end{itemize}
+
+{\bf 3.} You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do this,
+you must alter all the notices that refer to this License, so that they refer
+to the ordinary GNU General Public License, version 2, instead of to this
+License. (If a newer version than version 2 of the ordinary GNU General Public
+License has appeared, then you can specify that version instead if you wish.)
+Do not make any other change in these notices.
+
+Once this change is made in a given copy, it is irreversible for that copy, so
+the ordinary GNU General Public License applies to all subsequent copies and
+derivative works made from that copy.
+
+This option is useful when you wish to copy part of the code of the Library
+into a program that is not a library.
+
+{\bf 4.} You may copy and distribute the Library (or a portion or derivative
+of it, under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you accompany it with the complete
+corresponding machine-readable source code, which must be distributed under
+the terms of Sections 1 and 2 above on a medium customarily used for software
+interchange.
+
+If distribution of object code is made by offering access to copy from a
+designated place, then offering equivalent access to copy the source code from
+the same place satisfies the requirement to distribute the source code, even
+though third parties are not compelled to copy the source along with the
+object code.
+
+{\bf 5.} A program that contains no derivative of any portion of the Library,
+but is designed to work with the Library by being compiled or linked with it,
+is called a "work that uses the Library". Such a work, in isolation, is not
+a derivative work of the Library, and therefore falls outside the scope of
+this License.
+
+However, linking a "work that uses the Library" with the Library creates an
+executable that is a derivative of the Library (because it contains portions
+of the Library), rather than a "work that uses the library". The executable
+is therefore covered by this License. Section 6 states terms for distribution
+of such executables.
+
+When a "work that uses the Library" uses material from a header file that is
+part of the Library, the object code for the work may be a derivative work of
+the Library even though the source code is not. Whether this is true is
+especially significant if the work can be linked without the Library, or if
+the work is itself a library. The threshold for this to be true is not
+precisely defined by law.
+
+If such an object file uses only numerical parameters, data structure layouts
+and accessors, and small macros and small inline functions (ten lines or less
+in length), then the use of the object file is unrestricted, regardless of
+whether it is legally a derivative work. (Executables containing this object
+code plus portions of the Library will still fall under Section 6.)
+
+Otherwise, if the work is a derivative of the Library, you may distribute the
+object code for the work under the terms of Section 6. Any executables
+containing that work also fall under Section 6, whether or not they are linked
+directly with the Library itself.
+
+{\bf 6.} As an exception to the Sections above, you may also combine or link a
+"work that uses the Library" with the Library to produce a work containing
+portions of the Library, and distribute that work under terms of your choice,
+provided that the terms permit modification of the work for the customer's own
+use and reverse engineering for debugging such modifications.
+
+You must give prominent notice with each copy of the work that the Library is
+used in it and that the Library and its use are covered by this License. You
+must supply a copy of this License. If the work during execution displays
+copyright notices, you must include the copyright notice for the Library among
+them, as well as a reference directing the user to the copy of this License.
+Also, you must do one of these things:
+
+\begin{itemize}
+\item {\bf a)} Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever changes were
+ used in the work (which must be distributed under Sections 1 and 2 above);
+and, if the work is an executable linked with the Library, with the complete
+machine-readable "work that uses the Library", as object code and/or source
+code, so that the user can modify the Library and then relink to produce a
+modified executable containing the modified Library. (It is understood that
+the user who changes the contents of definitions files in the Library will
+not necessarily be able to recompile the application to use the modified
+definitions.)
+\item {\bf b)} Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a copy of the
+ library already present on the user's computer system, rather than copying
+library functions into the executable, and (2) will operate properly with a
+modified version of the library, if the user installs one, as long as the
+modified version is interface-compatible with the version that the work was
+made with.
+\item {\bf c)} Accompany the work with a written offer, valid for at least
+ three years, to give the same user the materials specified in Subsection 6a,
+ above, for a charge no more than the cost of performing this distribution.
+\item {\bf d)} If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above specified
+ materials from the same place.
+\item {\bf e)} Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+ \end{itemize}
+
+For an executable, the required form of the "work that uses the Library"
+must include any data and utility programs needed for reproducing the
+executable from it. However, as a special exception, the materials to be
+distributed need not include anything that is normally distributed (in either
+source or binary form) with the major components (compiler, kernel, and so on)
+of the operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+It may happen that this requirement contradicts the license restrictions of
+other proprietary libraries that do not normally accompany the operating
+system. Such a contradiction means you cannot use both them and the Library
+together in an executable that you distribute.
+
+{\bf 7.} You may place library facilities that are a work based on the Library
+side-by-side in a single library together with other library facilities not
+covered by this License, and distribute such a combined library, provided that
+the separate distribution of the work based on the Library and of the other
+library facilities is otherwise permitted, and provided that you do these two
+things:
+
+\begin{itemize}
+\item {\bf a)} Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library facilities. This must
+ be distributed under the terms of the Sections above.
+\item {\bf b)} Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining where to find
+ the accompanying uncombined form of the same work.
+\end{itemize}
+
+{\bf 8.} You may not copy, modify, sublicense, link with, or distribute the
+Library except as expressly provided under this License. Any attempt otherwise
+to copy, modify, sublicense, link with, or distribute the Library is void, and
+will automatically terminate your rights under this License. However, parties
+who have received copies, or rights, from you under this License will not have
+their licenses terminated so long as such parties remain in full compliance.
+
+{\bf 9.} You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or distribute
+the Library or its derivative works. These actions are prohibited by law if
+you do not accept this License. Therefore, by modifying or distributing the
+Library (or any work based on the Library), you indicate your acceptance of
+this License to do so, and all its terms and conditions for copying,
+distributing or modifying the Library or works based on it.
+
+{\bf 10.} Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the original
+licensor to copy, distribute, link with or modify the Library subject to these
+terms and conditions. You may not impose any further restrictions on the
+recipients' exercise of the rights granted herein. You are not responsible for
+enforcing compliance by third parties with this License.
+
+{\bf 11.} If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or otherwise)
+that contradict the conditions of this License, they do not excuse you from
+the conditions of this License. If you cannot distribute so as to satisfy
+simultaneously your obligations under this License and any other pertinent
+obligations, then as a consequence you may not distribute the Library at all.
+For example, if a patent license would not permit royalty-free redistribution
+of the Library by all those who receive copies directly or indirectly through
+you, then the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply, and
+the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any patents or
+other property right claims or to contest validity of any such claims; this
+section has the sole purpose of protecting the integrity of the free software
+distribution system which is implemented by public license practices. Many
+people have made generous contributions to the wide range of software
+distributed through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing to
+distribute software through any other system and a licensee cannot impose that
+choice.
+
+This section is intended to make thoroughly clear what is believed to be a
+consequence of the rest of this License.
+
+{\bf 12.} If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the original
+copyright holder who places the Library under this License may add an explicit
+geographical distribution limitation excluding those countries, so that
+distribution is permitted only in or among countries not thus excluded. In
+such case, this License incorporates the limitation as if written in the body
+of this License.
+
+{\bf 13.} The Free Software Foundation may publish revised and/or new versions
+of the Lesser General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and "any later
+version", you have the option of following the terms and conditions either of
+that version or of any later version published by the Free Software
+Foundation. If the Library does not specify a license version number, you may
+choose any version ever published by the Free Software Foundation.
+
+{\bf 14.} If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these, write to
+the author to ask for permission. For software which is copyrighted by the
+Free Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals of
+preserving the free status of all derivatives of our free software and of
+promoting the sharing and reuse of software generally.
+
+{\bf NO WARRANTY}
+
+{\bf 15.} BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE
+THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR
+IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO
+THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY
+PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+{\bf 16.} IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO
+LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR
+THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+END OF TERMS AND CONDITIONS

+\label{SEC45}
+\index[general]{Libraries!How to Apply These Terms to Your New }
+\index[general]{How to Apply These Terms to Your New Libraries }
+
+
+If you develop a new library, and you want it to be of the greatest possible
+use to the public, we recommend making it free software that everyone can
+redistribute and change. You can do so by permitting redistribution under
+these terms (or, alternatively, under the terms of the ordinary General Public
+License).
+
+To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+\footnotesize
+\begin{verbatim}
+{\it one line to give the library's name and an idea of what it does.}
+Copyright (C) {\it year} {\it name of author}
+This library is free software; you can redistribute it and/or
+modify it under the terms of the GNU Lesser General Public
+License as published by the Free Software Foundation; either
+version 2.1 of the License, or (at your option) any later version.
+This library is distributed in the hope that it will be useful,
+but WITHOUT ANY WARRANTY; without even the implied warranty of
+MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+Lesser General Public License for more details.

+
+Also add information on how to contact you by electronic and paper mail.

+\chapter{Migration and Copy}
+\label{MigrationChapter}
+\index[general]{Migration}
+\index[general]{Copy}
+
+The term Migration, as used in the context of Bacula, means moving data from
+one Volume to another. In particular it refers to a Job (similar to a backup
+job) that reads data that was previously backed up to a Volume and writes
+it to another Volume. As part of this process, the File catalog records
+associated with the first backup job are purged. In other words, Migration
+moves Bacula Job data from one Volume to another by reading the Job data
+from the Volume it is stored on, writing it to a different Volume in a
+different Pool, and then purging the database records for the first Job.
+
+The Copy process is essentially identical to the Migration feature with the
+exception that the Job that is copied is left unchanged. This essentially
+creates two identical copies of the same backup. However, the copy is treated
+as a copy rather than a backup job, and hence is not directly available for
+restore. If bacula founds a copy when a job record is purged (deleted) from the
+catalog, it will promote the copy as \textsl{real} backup and will make it
+available for automatic restore.
+
+The Copy and the Migration jobs run without using the File daemon by copying
+the data from the old backup Volume to a different Volume in a different Pool.
+
+The section process for which Job or Jobs are migrated
+can be based on quite a number of different criteria such as:
+\begin{itemize}
+\item a single previous Job
+\item a Volume
+\item a Client
+\item a regular expression matching a Job, Volume, or Client name
+\item the time a Job has been on a Volume
+\item high and low water marks (usage or occupation) of a Pool
+\item Volume size
+\end{itemize}
+
+The details of these selection criteria will be defined below.
+
+To run a Migration job, you must first define a Job resource very similar
+to a Backup Job but with {\bf Type = Migrate} instead of {\bf Type =
+Backup}. One of the key points to remember is that the Pool that is
+specified for the migration job is the only pool from which jobs will
+be migrated, with one exception noted below. In addition, the Pool to
+which the selected Job or Jobs will be migrated is defined by the {\bf
+Next Pool = ...} in the Pool resource specified for the Migration Job.
+
+Bacula permits pools to contain Volumes with different Media Types.
+However, when doing migration, this is a very undesirable condition. For
+migration to work properly, you should use pools containing only Volumes of
+the same Media Type for all migration jobs.
+
+The migration job normally is either manually started or starts
+from a Schedule much like a backup job. It searches
+for a previous backup Job or Jobs that match the parameters you have
+specified in the migration Job resource, primarily a {\bf Selection Type}
+(detailed a bit later). Then for
+each previous backup JobId found, the Migration Job will run a new Job which
+copies the old Job data from the previous Volume to a new Volume in
+the Migration Pool. It is possible that no prior Jobs are found for
+migration, in which case, the Migration job will simply terminate having
+done nothing, but normally at a minimum, three jobs are involved during a
+migration:
+
+\begin{itemize}
+\item The currently running Migration control Job. This is only
+ a control job for starting the migration child jobs.
+\item The previous Backup Job (already run). The File records
+ for this Job are purged if the Migration job successfully
+ terminates. The original data remains on the Volume until
+ it is recycled and rewritten.
+\item A new Migration Backup Job that moves the data from the
+ previous Backup job to the new Volume. If you subsequently
+ do a restore, the data will be read from this Job.
+\end{itemize}
+
+If the Migration control job finds a number of JobIds to migrate (e.g.
+it is asked to migrate one or more Volumes), it will start one new
+migration backup job for each JobId found on the specified Volumes.
+Please note that Migration doesn't scale too well since Migrations are
+done on a Job by Job basis. This if you select a very large volume or
+a number of volumes for migration, you may have a large number of
+Jobs that start. Because each job must read the same Volume, they will
+run consecutively (not simultaneously).
+
+\section{Migration and Copy Job Resource Directives}
+
+The following directives can appear in a Director's Job resource, and they
+are used to define a Migration job.
+
+\begin{description}
+\item [Pool = \lt{}Pool-name\gt{}] The Pool specified in the Migration
+ control Job is not a new directive for the Job resource, but it is
+ particularly important because it determines what Pool will be examined for
+ finding JobIds to migrate. The exception to this is when {\bf Selection
+ Type = SQLQuery}, in which case no Pool is used, unless you
+ specifically include it in the SQL query. Note, the Pool resource
+ referenced must contain a {\bf Next Pool = ...} directive to define
+ the Pool to which the data will be migrated.
+
+\item [Type = Migrate]
+ {\bf Migrate} is a new type that defines the job that is run as being a
+ Migration Job. A Migration Job is a sort of control job and does not have
+ any Files associated with it, and in that sense they are more or less like
+ an Admin job. Migration jobs simply check to see if there is anything to
+ Migrate then possibly start and control new Backup jobs to migrate the data
+ from the specified Pool to another Pool.
+
+\item [Type = Copy]
+ {\bf Copy} is a new type that defines the job that is run as being a
+ Copy Job. A Copy Job is a sort of control job and does not have
+ any Files associated with it, and in that sense they are more or less like
+ an Admin job. Copy jobs simply check to see if there is anything to
+ Copy then possibly start and control new Backup jobs to copy the data
+ from the specified Pool to another Pool.
+
+\item [Selection Type = \lt{}Selection-type-keyword\gt{}]
+ The \lt{}Selection-type-keyword\gt{} determines how the migration job
+ will go about selecting what JobIds to migrate. In most cases, it is
+ used in conjunction with a {\bf Selection Pattern} to give you fine
+ control over exactly what JobIds are selected. The possible values
+ for \lt{}Selection-type-keyword\gt{} are:
+ \begin{description}
+ \item [SmallestVolume] This selection keyword selects the volume with the
+ fewest bytes from the Pool to be migrated. The Pool to be migrated
+ is the Pool defined in the Migration Job resource. The migration
+ control job will then start and run one migration backup job for
+ each of the Jobs found on this Volume. The Selection Pattern, if
+ specified, is not used.
+
+ \item [OldestVolume] This selection keyword selects the volume with the
+ oldest last write time in the Pool to be migrated. The Pool to be
+ migrated is the Pool defined in the Migration Job resource. The
+ migration control job will then start and run one migration backup
+ job for each of the Jobs found on this Volume. The Selection
+ Pattern, if specified, is not used.
+
+ \item [Client] The Client selection type, first selects all the Clients
+ that have been backed up in the Pool specified by the Migration
+ Job resource, then it applies the {\bf Selection Pattern} (defined
+ below) as a regular expression to the list of Client names, giving
+ a filtered Client name list. All jobs that were backed up for those
+ filtered (regexed) Clients will be migrated.
+ The migration control job will then start and run one migration
+ backup job for each of the JobIds found for those filtered Clients.
+
+ \item [Volume] The Volume selection type, first selects all the Volumes
+ that have been backed up in the Pool specified by the Migration
+ Job resource, then it applies the {\bf Selection Pattern} (defined
+ below) as a regular expression to the list of Volume names, giving
+ a filtered Volume list. All JobIds that were backed up for those
+ filtered (regexed) Volumes will be migrated.
+ The migration control job will then start and run one migration
+ backup job for each of the JobIds found on those filtered Volumes.
+
+ \item [Job] The Job selection type, first selects all the Jobs (as
+ defined on the {\bf Name} directive in a Job resource)
+ that have been backed up in the Pool specified by the Migration
+ Job resource, then it applies the {\bf Selection Pattern} (defined
+ below) as a regular expression to the list of Job names, giving
+ a filtered Job name list. All JobIds that were run for those
+ filtered (regexed) Job names will be migrated. Note, for a given
+ Job named, they can be many jobs (JobIds) that ran.
+ The migration control job will then start and run one migration
+ backup job for each of the Jobs found.
+
+ \item [SQLQuery] The SQLQuery selection type, used the {\bf Selection
+ Pattern} as an SQL query to obtain the JobIds to be migrated.
+ The Selection Pattern must be a valid SELECT SQL statement for your
+ SQL engine, and it must return the JobId as the first field
+ of the SELECT.
+
+ \item [PoolOccupancy] This selection type will cause the Migration job
+ to compute the total size of the specified pool for all Media Types
+ combined. If it exceeds the {\bf Migration High Bytes} defined in
+ the Pool, the Migration job will migrate all JobIds beginning with
+ the oldest Volume in the pool (determined by Last Write time) until
+ the Pool bytes drop below the {\bf Migration Low Bytes} defined in the
+ Pool. This calculation should be consider rather approximative because
+ it is made once by the Migration job before migration is begun, and
+ thus does not take into account additional data written into the Pool
+ during the migration. In addition, the calculation of the total Pool
+ byte size is based on the Volume bytes saved in the Volume (Media)
+database
+ entries. The bytes calculate for Migration is based on the value stored
+ in the Job records of the Jobs to be migrated. These do not include the
+ Storage daemon overhead as is in the total Pool size. As a consequence,
+ normally, the migration will migrate more bytes than strictly necessary.
+
+ \item [PoolTime] The PoolTime selection type will cause the Migration job to
+ look at the time each JobId has been in the Pool since the job ended.
+ All Jobs in the Pool longer than the time specified on {\bf Migration Time}
+ directive in the Pool resource will be migrated.
+
+ \item [PoolUncopiedJobs] This selection which copies all jobs from a pool
+ to an other pool which were not copied before is available only for copy Jobs.
+
+ \end{description}
+
+\item [Selection Pattern = \lt{}Quoted-string\gt{}]
+ The Selection Patterns permitted for each Selection-type-keyword are
+ described above.
+
+ For the OldestVolume and SmallestVolume, this
+ Selection pattern is not used (ignored).
+
+ For the Client, Volume, and Job
+ keywords, this pattern must be a valid regular expression that will filter
+ the appropriate item names found in the Pool.
+
+ For the SQLQuery keyword, this pattern must be a valid SELECT SQL statement
+ that returns JobIds.
+
+\end{description}
+
+\section{Migration Pool Resource Directives}
+
+The following directives can appear in a Director's Pool resource, and they
+are used to define a Migration job.
+
+\begin{description}
+\item [Migration Time = \lt{}time-specification\gt{}]
+ If a PoolTime migration is done, the time specified here in seconds (time
+ modifiers are permitted -- e.g. hours, ...) will be used. If the
+ previous Backup Job or Jobs selected have been in the Pool longer than
+ the specified PoolTime, then they will be migrated.
+
+\item [Migration High Bytes = \lt{}byte-specification\gt{}]
+ This directive specifies the number of bytes in the Pool which will
+ trigger a migration if a {\bf PoolOccupancy} migration selection
+ type has been specified. The fact that the Pool
+ usage goes above this level does not automatically trigger a migration
+ job. However, if a migration job runs and has the PoolOccupancy selection
+ type set, the Migration High Bytes will be applied. Bacula does not
+ currently restrict a pool to have only a single Media Type, so you
+ must keep in mind that if you mix Media Types in a Pool, the results
+ may not be what you want, as the Pool count of all bytes will be
+ for all Media Types combined.
+
+\item [Migration Low Bytes = \lt{}byte-specification\gt{}]
+ This directive specifies the number of bytes in the Pool which will
+ stop a migration if a {\bf PoolOccupancy} migration selection
+ type has been specified and triggered by more than Migration High
+ Bytes being in the pool. In other words, once a migration job
+ is started with {\bf PoolOccupancy} migration selection and it
+ determines that there are more than Migration High Bytes, the
+ migration job will continue to run jobs until the number of
+ bytes in the Pool drop to or below Migration Low Bytes.
+
+\item [Next Pool = \lt{}pool-specification\gt{}]
+ The Next Pool directive specifies the pool to which Jobs will be
+ migrated. This directive is required to define the Pool into which
+ the data will be migrated. Without this directive, the migration job
+ will terminate in error.
+
+\item [Storage = \lt{}storage-specification\gt{}]
+ The Storage directive specifies what Storage resource will be used
+ for all Jobs that use this Pool. It takes precedence over any other
+ Storage specifications that may have been given such as in the
+ Schedule Run directive, or in the Job resource. We highly recommend
+ that you define the Storage resource to be used in the Pool rather
+ than elsewhere (job, schedule run, ...).
+\end{description}
+
+\section{Important Migration Considerations}
+\index[general]{Important Migration Considerations}
+\begin{itemize}
+\item Each Pool into which you migrate Jobs or Volumes {\bf must}
+ contain Volumes of only one Media Type.
+
+\item Migration takes place on a JobId by JobId basis. That is
+ each JobId is migrated in its entirety and independently
+ of other JobIds. Once the Job is migrated, it will be
+ on the new medium in the new Pool, but for the most part,
+ aside from having a new JobId, it will appear with all the
+ same characteristics of the original job (start, end time, ...).
+ The column RealEndTime in the catalog Job table will contain the
+ time and date that the Migration terminated, and by comparing
+ it with the EndTime column you can tell whether or not the
+ job was migrated. The original job is purged of its File
+ records, and its Type field is changed from "B" to "M" to
+ indicate that the job was migrated.
+
+\item Jobs on Volumes will be Migration only if the Volume is
+ marked, Full, Used, or Error. Volumes that are still
+ marked Append will not be considered for migration. This
+ prevents Bacula from attempting to read the Volume at
+ the same time it is writing it. It also reduces other deadlock
+ situations, as well as avoids the problem that you migrate a
+ Volume and later find new files appended to that Volume.
+
+\item As noted above, for the Migration High Bytes, the calculation
+ of the bytes to migrate is somewhat approximate.
+
+\item If you keep Volumes of different Media Types in the same Pool,
+ it is not clear how well migration will work. We recommend only
+ one Media Type per pool.
+
+\item It is possible to get into a resource deadlock where Bacula does
+ not find enough drives to simultaneously read and write all the
+ Volumes needed to do Migrations. For the moment, you must take
+ care as all the resource deadlock algorithms are not yet implemented.
+
+\item Migration is done only when you run a Migration job. If you set a
+ Migration High Bytes and that number of bytes is exceeded in the Pool
+ no migration job will automatically start. You must schedule the
+ migration jobs, and they must run for any migration to take place.
+
+\item If you migrate a number of Volumes, a very large number of Migration
+ jobs may start.
+
+\item Figuring out what jobs will actually be migrated can be a bit complicated
+ due to the flexibility provided by the regex patterns and the number of
+ different options. Turning on a debug level of 100 or more will provide
+ a limited amount of debug information about the migration selection
+ process.
+
+\item Bacula currently does only minimal Storage conflict resolution, so you
+ must take care to ensure that you don't try to read and write to the
+ same device or Bacula may block waiting to reserve a drive that it
+ will never find. In general, ensure that all your migration
+ pools contain only one Media Type, and that you always
+ migrate to pools with different Media Types.
+
+\item The {\bf Next Pool = ...} directive must be defined in the Pool
+ referenced in the Migration Job to define the Pool into which the
+ data will be migrated.
+
+\item Pay particular attention to the fact that data is migrated on a Job
+ by Job basis, and for any particular Volume, only one Job can read
+ that Volume at a time (no simultaneous read), so migration jobs that
+ all reference the same Volume will run sequentially. This can be a
+ potential bottle neck and does not scale very well to large numbers
+ of jobs.
+
+\item Only migration of Selection Types of Job and Volume have
+ been carefully tested. All the other migration methods (time,
+ occupancy, smallest, oldest, ...) need additional testing.
+
+\item Migration is only implemented for a single Storage daemon. You
+ cannot read on one Storage daemon and write on another.
+\end{itemize}
+
+
+\section{Example Migration Jobs}
+\index[general]{Example Migration Jobs}
+
+When you specify a Migration Job, you must specify all the standard
+directives as for a Job. However, certain such as the Level, Client, and
+FileSet, though they must be defined, are ignored by the Migration job
+because the values from the original job used instead.
+
+As an example, suppose you have the following Job that
+you run every night. To note: there is no Storage directive in the
+Job resource; there is a Storage directive in each of the Pool
+resources; the Pool to be migrated (File) contains a Next Pool
+directive that defines the output Pool (where the data is written
+by the migration job).
+
+\footnotesize
+\begin{verbatim}
+# Define the backup Job
+Job {
+ Name = "NightlySave"
+ Type = Backup
+ Level = Incremental # default
+ Client=rufus-fd
+ FileSet="Full Set"
+ Schedule = "WeeklyCycle"
+ Messages = Standard
+ Pool = Default
+}
+
+# Default pool definition
+Pool {
+ Name = Default
+ Pool Type = Backup
+ AutoPrune = yes
+ Recycle = yes
+ Next Pool = Tape
+ Storage = File
+ LabelFormat = "File"
+}
+
+# Tape pool definition
+Pool {
+ Name = Tape
+ Pool Type = Backup
+ AutoPrune = yes
+ Recycle = yes
+ Storage = DLTDrive
+}
+
+# Definition of File storage device
+Storage {
+ Name = File
+ Address = rufus
+ Password = "ccV3lVTsQRsdIUGyab0N4sMDavui2hOBkmpBU0aQKOr9"
+ Device = "File" # same as Device in Storage daemon
+ Media Type = File # same as MediaType in Storage daemon
+}
+
+# Definition of DLT tape storage device
+Storage {
+ Name = DLTDrive
+ Address = rufus
+ Password = "ccV3lVTsQRsdIUGyab0N4sMDavui2hOBkmpBU0aQKOr9"
+ Device = "HP DLT 80" # same as Device in Storage daemon
+ Media Type = DLT8000 # same as MediaType in Storage daemon
+}
+
+\end{verbatim}
+\normalsize
+
+Where we have included only the essential information -- i.e. the
+Director, FileSet, Catalog, Client, Schedule, and Messages resources are
+omitted.
+
+As you can see, by running the NightlySave Job, the data will be backed up
+to File storage using the Default pool to specify the Storage as File.
+
+Now, if we add the following Job resource to this conf file.
+
+\footnotesize
+\begin{verbatim}
+Job {
+ Name = "migrate-volume"
+ Type = Migrate
+ Level = Full
+ Client = rufus-fd
+ FileSet = "Full Set"
+ Messages = Standard
+ Pool = Default
+ Maximum Concurrent Jobs = 4
+ Selection Type = Volume
+ Selection Pattern = "File"
+}
+\end{verbatim}
+\normalsize
+
+and then run the job named {\bf migrate-volume}, all volumes in the Pool
+named Default (as specified in the migrate-volume Job that match the
+regular expression pattern {\bf File} will be migrated to tape storage
+DLTDrive because the {\bf Next Pool} in the Default Pool specifies that
+Migrations should go to the pool named {\bf Tape}, which uses
+Storage {\bf DLTDrive}.
+
+If instead, we use a Job resource as follows:
+
+\footnotesize
+\begin{verbatim}
+Job {
+ Name = "migrate"
+ Type = Migrate
+ Level = Full
+ Client = rufus-fd
+ FileSet="Full Set"
+ Messages = Standard
+ Pool = Default
+ Maximum Concurrent Jobs = 4
+ Selection Type = Job
+ Selection Pattern = ".*Save"
+}
+\end{verbatim}
+\normalsize
+
+All jobs ending with the name Save will be migrated from the File Default to
+the Tape Pool, or from File storage to Tape storage.

+\chapter{New Features in 3.0.2}
+
+This chapter presents the new features added to the development 3.0.2
+versions to be released as Bacula version 3.0.2 sometime in 2009.
+
+\section{Source Address}
+\index[general]{Source Address}
+
+A feature has been added which allows the administrator to specify the address
+from which the director and file daemons will attempt connections from. This
+may be used to simplify system configuration overhead when working in complex
+networks utilizing multi-homing and policy-routing.
+
+To accomplish this, two new configuration directives have been implemented:
+\begin{verbatim}
+FileDaemon {
+ FDSourceAddress=10.0.1.20 # Always initiate connections from this address
+}
+
+Director {
+ DirSourceAddress=10.0.1.10 # Always initiate connections from this address
+}
+\end{verbatim}
+
+Simply adding specific host routes would have an undesirable side-effect: any
+application trying to contact the destination host would be forced to use the
+more specific route, possibly diverting management traffic onto a backup VLAN.
+Instead of adding host routes for each client connected to a multi-homed backup
+server (for example where there are management and backup VLANs), one can
+use the new directives to specify a specific source address at the application
+level.
+
+Additionally, this allows the simplification and abstraction of firewall rules
+when dealing with a Hot-Standby director or storage daemon configuration. The
+Hot-standby pair may share a CARP address, which connections must be sourced
+from, while system services listen and act from the unique interface addresses.
+
+This project was funded by Collaborative Fusion, Inc.
+
+\section{Show volume availability when doing restore}
+
+When doing a restore the restore selection dialog ends by displaying this
+screen:
+
+\begin{verbatim}
+ The job will require the following
+ Volume(s) Storage(s) SD Device(s)
+ ===========================================================================
+ *000741L3 LTO-4 LTO3
+ *000866L3 LTO-4 LTO3
+ *000765L3 LTO-4 LTO3
+ *000764L3 LTO-4 LTO3
+ *000756L3 LTO-4 LTO3
+ *001759L3 LTO-4 LTO3
+ *001763L3 LTO-4 LTO3
+ 001762L3 LTO-4 LTO3
+ 001767L3 LTO-4 LTO3
+
+Volumes marked with ``*'' are online.
+\end{verbatim}
+
+This should help getting large restores through minimizing the time spent
+waiting for operator to drop by and change tapes in the library.
+
+This project was funded by Bacula Systems.
+
+\chapter{New Features in 3.0.0}
+\label{NewFeaturesChapter}
+\index[general]{New Features}
+
+This chapter presents the new features added to the development 2.5.x
+versions to be released as Bacula version 3.0.0 sometime in April 2009.
+
+\section{Accurate Backup}
+\index[general]{Accurate Backup}
+
+As with most other backup programs, by default Bacula decides what files to
+backup for Incremental and Differental backup by comparing the change
+(st\_ctime) and modification (st\_mtime) times of the file to the time the last
+backup completed. If one of those two times is later than the last backup
+time, then the file will be backed up. This does not, however, permit tracking
+what files have been deleted and will miss any file with an old time that may
+have been restored to or moved onto the client filesystem.
+
+\subsection{Accurate = \lt{}yes|no\gt{}}
+If the {\bf Accurate = \lt{}yes|no\gt{}} directive is enabled (default no) in
+the Job resource, the job will be run as an Accurate Job. For a {\bf Full}
+backup, there is no difference, but for {\bf Differential} and {\bf
+ Incremental} backups, the Director will send a list of all previous files
+backed up, and the File daemon will use that list to determine if any new files
+have been added or or moved and if any files have been deleted. This allows
+Bacula to make an accurate backup of your system to that point in time so that
+if you do a restore, it will restore your system exactly.
+
+One note of caution
+about using Accurate backup is that it requires more resources (CPU and memory)
+on both the Director and the Client machines to create the list of previous
+files backed up, to send that list to the File daemon, for the File daemon to
+keep the list (possibly very big) in memory, and for the File daemon to do
+comparisons between every file in the FileSet and the list. In particular,
+if your client has lots of files (more than a few million), you will need
+lots of memory on the client machine.
+
+Accurate must not be enabled when backing up with a plugin that is not
+specially designed to work with Accurate. If you enable it, your restores
+will probably not work correctly.
+
+This project was funded by Bacula Systems.
+
+
+
+\section{Copy Jobs}
+\index[general]{Copy Jobs}
+
+A new {\bf Copy} job type 'C' has been implemented. It is similar to the
+existing Migration feature with the exception that the Job that is copied is
+left unchanged. This essentially creates two identical copies of the same
+backup. However, the copy is treated as a copy rather than a backup job, and
+hence is not directly available for restore. The {\bf restore} command lists
+copy jobs and allows selection of copies by using \texttt{jobid=}
+option. If the keyword {\bf copies} is present on the command line, Bacula will
+display the list of all copies for selected jobs.
+
+\begin{verbatim}
+* restore copies
+[...]
+These JobIds have copies as follows:
++-------+------------------------------------+-----------+------------------+
+| JobId | Job | CopyJobId | MediaType |
++-------+------------------------------------+-----------+------------------+
+| 2 | CopyJobSave.2009-02-17_16.31.00.11 | 7 | DiskChangerMedia |
++-------+------------------------------------+-----------+------------------+
++-------+-------+----------+----------+---------------------+------------------+
+| JobId | Level | JobFiles | JobBytes | StartTime | VolumeName |
++-------+-------+----------+----------+---------------------+------------------+
+| 19 | F | 6274 | 76565018 | 2009-02-17 16:30:45 | ChangerVolume002 |
+| 2 | I | 1 | 5 | 2009-02-17 16:30:51 | FileVolume001 |
++-------+-------+----------+----------+---------------------+------------------+
+You have selected the following JobIds: 19,2
+
+Building directory tree for JobId(s) 19,2 ... ++++++++++++++++++++++++++++++++++++++++++++
+5,611 files inserted into the tree.
+...
+\end{verbatim}
+
+
+The Copy Job runs without using the File daemon by copying the data from the
+old backup Volume to a different Volume in a different Pool. See the Migration
+documentation for additional details. For copy Jobs there is a new selection
+criterium named PoolUncopiedJobs which copies all jobs from a pool to an other
+pool which were not copied before. Next to that the client, volume, job or sql
+query are possible ways of selecting jobs which should be copied. Selection
+types like smallestvolume, oldestvolume, pooloccupancy and pooltime are
+probably more suited for migration jobs only. But we could imagine some people
+have a valid use for those kind of copy jobs too.
+
+If bacula founds a copy when a job record is purged (deleted) from the catalog,
+it will promote the copy as \textsl{real} backup and will make it available for
+automatic restore. If more than one copy is available, it will promote the copy
+with the smallest jobid.
+
+A nice solution which can be build with the new copy jobs is what is
+called the disk-to-disk-to-tape backup (DTDTT). A sample config could
+look somethings like the one below:
+
+\begin{verbatim}
+Pool {
+ Name = FullBackupsVirtualPool
+ Pool Type = Backup
+ Purge Oldest Volume = Yes
+ Storage = vtl
+ NextPool = FullBackupsTapePool
+}
+
+Pool {
+ Name = FullBackupsTapePool
+ Pool Type = Backup
+ Recycle = Yes
+ AutoPrune = Yes
+ Volume Retention = 365 days
+ Storage = superloader
+}
+
+#
+# Fake fileset for copy jobs
+#
+Fileset {
+ Name = None
+ Include {
+ Options {
+ signature = MD5
+ }
+ }
+}
+
+#
+# Fake client for copy jobs
+#
+Client {
+ Name = None
+ Address = localhost
+ Password = "NoNe"
+ Catalog = MyCatalog
+}
+
+#
+# Default template for a CopyDiskToTape Job
+#
+JobDefs {
+ Name = CopyDiskToTape
+ Type = Copy
+ Messages = StandardCopy
+ Client = None
+ FileSet = None
+ Selection Type = PoolUncopiedJobs
+ Maximum Concurrent Jobs = 10
+ SpoolData = No
+ Allow Duplicate Jobs = Yes
+ Allow Higher Duplicates = No
+ Cancel Queued Duplicates = No
+ Cancel Running Duplicates = No
+ Priority = 13
+}
+
+Schedule {
+ Name = DaySchedule7:00
+ Run = Level=Full daily at 7:00
+}
+
+Job {
+ Name = CopyDiskToTapeFullBackups
+ Enabled = Yes
+ Schedule = DaySchedule7:00
+ Pool = FullBackupsVirtualPool
+ JobDefs = CopyDiskToTape
+}
+\end{verbatim}
+
+The example above had 2 pool which are copied using the PoolUncopiedJobs
+selection criteria. Normal Full backups go to the Virtual pool and are copied
+to the Tape pool the next morning.
+
+The command \texttt{list copies [jobid=x,y,z]} lists copies for a given
+\textbf{jobid}.
+
+\begin{verbatim}
+*list copies
++-------+------------------------------------+-----------+------------------+
+| JobId | Job | CopyJobId | MediaType |
++-------+------------------------------------+-----------+------------------+
+| 9 | CopyJobSave.2008-12-20_22.26.49.05 | 11 | DiskChangerMedia |
++-------+------------------------------------+-----------+------------------+
+\end{verbatim}
+
+\section{ACL Updates}
+\index[general]{ACL Updates}
+The whole ACL code had been overhauled and in this version each platforms has
+different streams for each type of acl available on such an platform. As ACLs
+between platforms tend to be not that portable (most implement POSIX acls but
+some use an other draft or a completely different format) we currently only
+allow certain platform specific ACL streams to be decoded and restored on the
+same platform that they were created on. The old code allowed to restore ACL
+cross platform but the comments already mention that not being to wise. For
+backward compatability the new code will accept the two old ACL streams and
+handle those with the platform specific handler. But for all new backups it
+will save the ACLs using the new streams.
+
+Currently the following platforms support ACLs:
+
+\begin{itemize}
+ \item {\bf AIX}
+ \item {\bf Darwin/OSX}
+ \item {\bf FreeBSD}
+ \item {\bf HPUX}
+ \item {\bf IRIX}
+ \item {\bf Linux}
+ \item {\bf Tru64}
+ \item {\bf Solaris}
+\end{itemize}
+
+Currently we support the following ACL types (these ACL streams use a reserved
+part of the stream numbers):
+
+\begin{itemize}
+\item {\bf STREAM\_ACL\_AIX\_TEXT} 1000 AIX specific string representation from
+ acl\_get
+ \item {\bf STREAM\_ACL\_DARWIN\_ACCESS\_ACL} 1001 Darwin (OSX) specific acl\_t
+ string representation from acl\_to\_text (POSIX acl)
+ \item {\bf STREAM\_ACL\_FREEBSD\_DEFAULT\_ACL} 1002 FreeBSD specific acl\_t
+ string representation from acl\_to\_text (POSIX acl) for default acls.
+ \item {\bf STREAM\_ACL\_FREEBSD\_ACCESS\_ACL} 1003 FreeBSD specific acl\_t
+ string representation from acl\_to\_text (POSIX acl) for access acls.
+ \item {\bf STREAM\_ACL\_HPUX\_ACL\_ENTRY} 1004 HPUX specific acl\_entry
+ string representation from acltostr (POSIX acl)
+ \item {\bf STREAM\_ACL\_IRIX\_DEFAULT\_ACL} 1005 IRIX specific acl\_t string
+ representation from acl\_to\_text (POSIX acl) for default acls.
+ \item {\bf STREAM\_ACL\_IRIX\_ACCESS\_ACL} 1006 IRIX specific acl\_t string
+ representation from acl\_to\_text (POSIX acl) for access acls.
+ \item {\bf STREAM\_ACL\_LINUX\_DEFAULT\_ACL} 1007 Linux specific acl\_t
+ string representation from acl\_to\_text (POSIX acl) for default acls.
+ \item {\bf STREAM\_ACL\_LINUX\_ACCESS\_ACL} 1008 Linux specific acl\_t string
+ representation from acl\_to\_text (POSIX acl) for access acls.
+ \item {\bf STREAM\_ACL\_TRU64\_DEFAULT\_ACL} 1009 Tru64 specific acl\_t
+ string representation from acl\_to\_text (POSIX acl) for default acls.
+ \item {\bf STREAM\_ACL\_TRU64\_DEFAULT\_DIR\_ACL} 1010 Tru64 specific acl\_t
+ string representation from acl\_to\_text (POSIX acl) for default acls.
+ \item {\bf STREAM\_ACL\_TRU64\_ACCESS\_ACL} 1011 Tru64 specific acl\_t string
+ representation from acl\_to\_text (POSIX acl) for access acls.
+ \item {\bf STREAM\_ACL\_SOLARIS\_ACLENT} 1012 Solaris specific aclent\_t
+ string representation from acltotext or acl\_totext (POSIX acl)
+ \item {\bf STREAM\_ACL\_SOLARIS\_ACE} 1013 Solaris specific ace\_t string
+ representation from from acl\_totext (NFSv4 or ZFS acl)
+\end{itemize}
+
+In future versions we might support conversion functions from one type of acl
+into an other for types that are either the same or easily convertable. For now
+the streams are seperate and restoring them on a platform that doesn't
+recognize them will give you a warning.
+
+\section{Extended Attributes}
+\index[general]{Extended Attributes}
+Something that was on the project list for some time is now implemented for
+platforms that support a similar kind of interface. Its the support for backup
+and restore of so called extended attributes. As extended attributes are so
+platform specific these attributes are saved in seperate streams for each
+platform. Restores of the extended attributes can only be performed on the
+same platform the backup was done. There is support for all types of extended
+attributes, but restoring from one type of filesystem onto an other type of
+filesystem on the same platform may lead to supprises. As extended attributes
+can contain any type of data they are stored as a series of so called
+value-pairs. This data must be seen as mostly binary and is stored as such.
+As security labels from selinux are also extended attributes this option also
+stores those labels and no specific code is enabled for handling selinux
+security labels.
+
+Currently the following platforms support extended attributes:
+\begin{itemize}
+ \item {\bf Darwin/OSX}
+ \item {\bf FreeBSD}
+ \item {\bf Linux}
+ \item {\bf NetBSD}
+\end{itemize}
+
+On linux acls are also extended attributes, as such when you enable ACLs on a
+Linux platform it will NOT save the same data twice e.g. it will save the ACLs
+and not the same exteneded attribute.
+
+To enable the backup of extended attributes please add the following to your
+fileset definition.
+\begin{verbatim}
+ FileSet {
+ Name = "MyFileSet"
+ Include {
+ Options {
+ signature = MD5
+ xattrsupport = yes
+ }
+ File = ...
+ }
+ }
+\end{verbatim}
+
+\section{Shared objects}
+\index[general]{Shared objects}
+A default build of Bacula will now create the libraries as shared objects
+(.so) rather than static libraries as was previously the case.
+The shared libraries are built using {\bf libtool} so it should be quite
+portable.
+
+An important advantage of using shared objects is that on a machine with the
+Directory, File daemon, the Storage daemon, and a console, you will have only
+one copy of the code in memory rather than four copies. Also the total size of
+the binary release is smaller since the library code appears only once rather
+than once for every program that uses it; this results in significant reduction
+in the size of the binaries particularly for the utility tools.
+
+In order for the system loader to find the shared objects when loading the
+Bacula binaries, the Bacula shared objects must either be in a shared object
+directory known to the loader (typically /usr/lib) or they must be in the
+directory that may be specified on the {\bf ./configure} line using the {\bf
+ {-}{-}libdir} option as:
+
+\begin{verbatim}
+ ./configure --libdir=/full-path/dir
+\end{verbatim}
+
+the default is /usr/lib. If {-}{-}libdir is specified, there should be
+no need to modify your loader configuration provided that
+the shared objects are installed in that directory (Bacula
+does this with the make install command). The shared objects
+that Bacula references are:
+
+\begin{verbatim}
+libbaccfg.so
+libbacfind.so
+libbacpy.so
+libbac.so
+\end{verbatim}
+
+These files are symbolically linked to the real shared object file,
+which has a version number to permit running multiple versions of
+the libraries if desired (not normally the case).
+
+If you have problems with libtool or you wish to use the old
+way of building static libraries, or you want to build a static
+version of Bacula you may disable
+libtool on the configure command line with:
+
+\begin{verbatim}
+ ./configure --disable-libtool
+\end{verbatim}
+
+
+\section{Building Static versions of Bacula}
+\index[general]{Static linking}
+In order to build static versions of Bacula, in addition
+to configuration options that were needed you now must
+also add --disable-libtool. Example
+
+\begin{verbatim}
+ ./configure --enable-static-client-only --disable-libtool
+\end{verbatim}
+
+
+\section{Virtual Backup (Vbackup)}
+\index[general]{Virtual Backup}
+\index[general]{Vbackup}
+
+Bacula's virtual backup feature is often called Synthetic Backup or
+Consolidation in other backup products. It permits you to consolidate the
+previous Full backup plus the most recent Differential backup and any
+subsequent Incremental backups into a new Full backup. This new Full
+backup will then be considered as the most recent Full for any future
+Incremental or Differential backups. The VirtualFull backup is
+accomplished without contacting the client by reading the previous backup
+data and writing it to a volume in a different pool.
+
+In some respects the Vbackup feature works similar to a Migration job, in
+that Bacula normally reads the data from the pool specified in the
+Job resource, and writes it to the {\bf Next Pool} specified in the
+Job resource. Note, this means that usually the output from the Virtual
+Backup is written into a different pool from where your prior backups
+are saved. Doing it this way guarantees that you will not get a deadlock
+situation attempting to read and write to the same volume in the Storage
+daemon. If you then want to do subsequent backups, you may need to
+move the Virtual Full Volume back to your normal backup pool.
+Alternatively, you can set your {\bf Next Pool} to point to the current
+pool. This will cause Bacula to read and write to Volumes in the
+current pool. In general, this will work, because Bacula will
+not allow reading and writing on the same Volume. In any case, once
+a VirtualFull has been created, and a restore is done involving the
+most current Full, it will read the Volume or Volumes by the VirtualFull
+regardless of in which Pool the Volume is found.
+
+The Vbackup is enabled on a Job by Job in the Job resource by specifying
+a level of {\bf VirtualFull}.
+
+A typical Job resource definition might look like the following:
+
+\begin{verbatim}
+Job {
+ Name = "MyBackup"
+ Type = Backup
+ Client=localhost-fd
+ FileSet = "Full Set"
+ Storage = File
+ Messages = Standard
+ Pool = Default
+ SpoolData = yes
+}
+
+# Default pool definition
+Pool {
+ Name = Default
+ Pool Type = Backup
+ Recycle = yes # Automatically recycle Volumes
+ AutoPrune = yes # Prune expired volumes
+ Volume Retention = 365d # one year
+ NextPool = Full
+ Storage = File
+}
+
+Pool {
+ Name = Full
+ Pool Type = Backup
+ Recycle = yes # Automatically recycle Volumes
+ AutoPrune = yes # Prune expired volumes
+ Volume Retention = 365d # one year
+ Storage = DiskChanger
+}
+
+# Definition of file storage device
+Storage {
+ Name = File
+ Address = localhost
+ Password = "xxx"
+ Device = FileStorage
+ Media Type = File
+ Maximum Concurrent Jobs = 5
+}
+
+# Definition of DDS Virtual tape disk storage device
+Storage {
+ Name = DiskChanger
+ Address = localhost # N.B. Use a fully qualified name here
+ Password = "yyy"
+ Device = DiskChanger
+ Media Type = DiskChangerMedia
+ Maximum Concurrent Jobs = 4
+ Autochanger = yes
+}
+\end{verbatim}
+
+Then in bconsole or via a Run schedule, you would run the job as:
+
+\begin{verbatim}
+run job=MyBackup level=Full
+run job=MyBackup level=Incremental
+run job=MyBackup level=Differential
+run job=MyBackup level=Incremental
+run job=MyBackup level=Incremental
+\end{verbatim}
+
+So providing there were changes between each of those jobs, you would end up
+with a Full backup, a Differential, which includes the first Incremental
+backup, then two Incremental backups. All the above jobs would be written to
+the {\bf Default} pool.
+
+To consolidate those backups into a new Full backup, you would run the
+following:
+
+\begin{verbatim}
+run job=MyBackup level=VirtualFull
+\end{verbatim}
+
+And it would produce a new Full backup without using the client, and the output
+would be written to the {\bf Full} Pool which uses the Diskchanger Storage.
+
+If the Virtual Full is run, and there are no prior Jobs, the Virtual Full will
+fail with an error.
+
+Note, the Start and End time of the Virtual Full backup is set to the
+values for the last job included in the Virtual Full (in the above example,
+it is an Increment). This is so that if another incremental is done, which
+will be based on the Virtual Full, it will backup all files from the
+last Job included in the Virtual Full rather than from the time the Virtual
+Full was actually run.
+
+
+
+\section{Catalog Format}
+\index[general]{Catalog Format}
+Bacula 3.0 comes with some changes to the catalog format. The upgrade
+operation will convert the FileId field of the File table from 32 bits (max 4
+billion table entries) to 64 bits (very large number of items). The
+conversion process can take a bit of time and will likely DOUBLE THE SIZE of
+your catalog during the conversion. Also you won't be able to run jobs during
+this conversion period. For example, a 3 million file catalog will take 2
+minutes to upgrade on a normal machine. Please don't forget to make a valid
+backup of your database before executing the upgrade script. See the
+ReleaseNotes for additional details.
+
+\section{64 bit Windows Client}
+\index[general]{Win64 Client}
+Unfortunately, Microsoft's implementation of Volume Shadown Copy (VSS) on
+their 64 bit OS versions is not compatible with a 32 bit Bacula Client.
+As a consequence, we are also releasing a 64 bit version of the Bacula
+Windows Client (win64bacula-3.0.0.exe) that does work with VSS.
+These binaries should only be installed on 64 bit Windows operating systems.
+What is important is not your hardware but whether or not you have
+a 64 bit version of the Windows OS.
+
+Compared to the Win32 Bacula Client, the 64 bit release contains a few differences:
+\begin{enumerate}
+\item Before installing the Win64 Bacula Client, you must totally
+ deinstall any prior 2.4.x Client installation using the
+ Bacula deinstallation (see the menu item). You may want
+ to save your .conf files first.
+\item Only the Client (File daemon) is ported to Win64, the Director
+ and the Storage daemon are not in the 64 bit Windows installer.
+\item bwx-console is not yet ported.
+\item bconsole is ported but it has not been tested.
+\item The documentation is not included in the installer.
+\item Due to Vista security restrictions imposed on a default installation
+ of Vista, before upgrading the Client, you must manually stop
+ any prior version of Bacula from running, otherwise the install
+ will fail.
+\item Due to Vista security restrictions imposed on a default installation
+ of Vista, attempting to edit the conf files via the menu items
+ will fail. You must directly edit the files with appropriate
+ permissions. Generally double clicking on the appropriate .conf
+ file will work providing you have sufficient permissions.
+\item All Bacula files are now installed in
+ {\bf C:/Program Files/Bacula} except the main menu items,
+ which are installed as before. This vastly simplifies the installation.
+\item If you are running on a foreign language version of Windows, most
+ likely {\bf C:/Program Files} does not exist, so you should use the
+ Custom installation and enter an appropriate location to install
+ the files.
+\item The 3.0.0 Win32 Client continues to install files in the locations used
+ by prior versions. For the next version we will convert it to use
+ the same installation conventions as the Win64 version.
+\end{enumerate}
+
+This project was funded by Bacula Systems.
+
+
+\section{Duplicate Job Control}
+\index[general]{Duplicate Jobs}
+The new version of Bacula provides four new directives that
+give additional control over what Bacula does if duplicate jobs
+are started. A duplicate job in the sense we use it here means
+a second or subsequent job with the same name starts. This
+happens most frequently when the first job runs longer than expected because no
+tapes are available.
+
+The four directives each take as an argument a {\bf yes} or {\bf no} value and
+are specified in the Job resource.
+
+They are:
+
+\subsection{Allow Duplicate Jobs = \lt{}yes|no\gt{}}
+\index[general]{Allow Duplicate Jobs}
+ If this directive is enabled duplicate jobs will be run. If
+ the directive is set to {\bf no} (default) then only one job of a given name
+ may run at one time, and the action that Bacula takes to ensure only
+ one job runs is determined by the other directives (see below).
+
+ If {\bf Allow Duplicate Jobs} is set to {\bf no} and two jobs
+ are present and none of the three directives given below permit
+ cancelling a job, then the current job (the second one started)
+ will be cancelled.
+
+
+\subsection{Allow Higher Duplicates = \lt{}yes|no\gt{}}
+\index[general]{Allow Higher Duplicates}
+ If this directive is set to {\bf yes} (default) the job with a higher
+ priority (lower priority number) will be permitted to run, and
+ the current job will be cancelled. If the
+ priorities of the two jobs are the same, the outcome is determined by
+ other directives (see below).
+
+\subsection{Cancel Queued Duplicates = \lt{}yes|no\gt{}}
+\index[general]{Cancel Queued Duplicates}
+ If {\bf Allow Duplicate Jobs} is set to {\bf no} and

+
+\subsection{Cancel Running Duplicates = \lt{}yes|no\gt{}}
+\index[general]{Cancel Running Duplicates}
+ If {\bf Allow Duplicate Jobs} is set to {\bf no} and
+ if this directive is set to {\bf yes} any job that is already running
+ will be canceled. The default is {\bf no}.
+
+
+\section{TLS Authentication}
+\index[general]{TLS Authentication}
+In Bacula version 2.5.x and later, in addition to the normal Bacula
+CRAM-MD5 authentication that is used to authenticate each Bacula
+connection, you can specify that you want TLS Authentication as well,
+which will provide more secure authentication.
+
+This new feature uses Bacula's existing TLS code (normally used for
+communications encryption) to do authentication. To use it, you must
+specify all the TLS directives normally used to enable communications
+encryption (TLS Enable, TLS Verify Peer, TLS Certificate, ...) and
+a new directive:
+
+\subsection{TLS Authenticate = yes}
+\begin{verbatim}
+TLS Authenticate = yes
+\end{verbatim}
+
+in the main daemon configuration resource (Director for the Director,
+Client for the File daemon, and Storage for the Storage daemon).
+
+When {\bf TLS Authenticate} is enabled, after doing the CRAM-MD5
+authentication, Bacula will also do TLS authentication, then TLS
+encryption will be turned off, and the rest of the communication between
+the two Bacula daemons will be done without encryption.
+
+If you want to encrypt communications data, use the normal TLS directives
+but do not turn on {\bf TLS Authenticate}.
+
+\section{bextract non-portable Win32 data}
+\index[general]{bextract handles Win32 non-portable data}
+{\bf bextract} has been enhanced to be able to restore
+non-portable Win32 data to any OS. Previous versions were
+unable to restore non-portable Win32 data to machines that
+did not have the Win32 BackupRead and BackupWrite API calls.
+
+\section{State File updated at Job Termination}
+\index[general]{State File}
+In previous versions of Bacula, the state file, which provides a
+summary of previous jobs run in the {\bf status} command output was
+updated only when Bacula terminated, thus if the daemon crashed, the
+state file might not contain all the run data. This version of
+the Bacula daemons updates the state file on each job termination.
+
+\section{MaxFullInterval = \lt{}time-interval\gt{}}
+\index[general]{MaxFullInterval}
+The new Job resource directive {\bf Max Full Interval = \lt{}time-interval\gt{}}
+can be used to specify the maximum time interval between {\bf Full} backup
+jobs. When a job starts, if the time since the last Full backup is
+greater than the specified interval, and the job would normally be an
+{\bf Incremental} or {\bf Differential}, it will be automatically
+upgraded to a {\bf Full} backup.
+
+\section{MaxDiffInterval = \lt{}time-interval\gt{}}
+\index[general]{MaxDiffInterval}
+The new Job resource directive {\bf Max Diff Interval = \lt{}time-interval\gt{}}
+can be used to specify the maximum time interval between {\bf Differential} backup
+jobs. When a job starts, if the time since the last Differential backup is
+greater than the specified interval, and the job would normally be an
+{\bf Incremental}, it will be automatically
+upgraded to a {\bf Differential} backup.
+
+\section{Honor No Dump Flag = \lt{}yes|no\gt{}}
+\index[general]{MaxDiffInterval}
+On FreeBSD systems, each file has a {\bf no dump flag} that can be set
+by the user, and when it is set it is an indication to backup programs
+to not backup that particular file. This version of Bacula contains a
+new Options directive within a FileSet resource, which instructs Bacula to
+obey this flag. The new directive is:
+
+\begin{verbatim}
+ Honor No Dump Flag = yes|no
+\end{verbatim}
+
+The default value is {\bf no}.
+
+
+\section{Exclude Dir Containing = \lt{}filename-string\gt{}}
+\index[general]{IgnoreDir}
+The {\bf ExcludeDirContaining = \lt{}filename\gt{}} is a new directive that
+can be added to the Include section of the FileSet resource. If the specified
+filename ({\bf filename-string}) is found on the Client in any directory to be
+backed up, the whole directory will be ignored (not backed up). For example:
+
+\begin{verbatim}
+ # List of files to be backed up
+ FileSet {
+ Name = "MyFileSet"
+ Include {
+ Options {
+ signature = MD5
+ }
+ File = /home
+ Exclude Dir Containing = .excludeme
+ }
+ }
+\end{verbatim}
+
+But in /home, there may be hundreds of directories of users and some
+people want to indicate that they don't want to have certain
+directories backed up. For example, with the above FileSet, if
+the user or sysadmin creates a file named {\bf .excludeme} in
+specific directories, such as
+
+\begin{verbatim}
+ /home/user/www/cache/.excludeme
+ /home/user/temp/.excludeme
+\end{verbatim}
+
+then Bacula will not backup the two directories named:
+
+\begin{verbatim}
+ /home/user/www/cache
+ /home/user/temp
+\end{verbatim}
+
+NOTE: subdirectories will not be backed up. That is, the directive
+applies to the two directories in question and any children (be they
+files, directories, etc).
+
+
+\section{Bacula Plugins}
+\index[general]{Plugin}
+Support for shared object plugins has been implemented in the Linux, Unix
+and Win32 File daemons. The API will be documented separately in
+the Developer's Guide or in a new document. For the moment, there is
+a single plugin named {\bf bpipe} that allows an external program to
+get control to backup and restore a file.
+
+Plugins are also planned (partially implemented) in the Director and the
+Storage daemon.
+
+\subsection{Plugin Directory}
+\index[general]{Plugin Directory}
+Each daemon (DIR, FD, SD) has a new {\bf Plugin Directory} directive that may
+be added to the daemon definition resource. The directory takes a quoted
+string argument, which is the name of the directory in which the daemon can
+find the Bacula plugins. If this directive is not specified, Bacula will not
+load any plugins. Since each plugin has a distinctive name, all the daemons
+can share the same plugin directory.
+
+\subsection{Plugin Options}
+\index[general]{Plugin Options}
+The {\bf Plugin Options} directive takes a quoted string
+arguement (after the equal sign) and may be specified in the
+Job resource. The options specified will be passed to all plugins
+when they are run. This each plugin must know what it is looking
+for. The value defined in the Job resource can be modified
+by the user when he runs a Job via the {\bf bconsole} command line
+prompts.
+
+Note: this directive may be specified, and there is code to modify
+the string in the run command, but the plugin options are not yet passed to
+the plugin (i.e. not fully implemented).
+
+\subsection{Plugin Options ACL}
+\index[general]{Plugin Options ACL}
+The {\bf Plugin Options ACL} directive may be specified in the
+Director's Console resource. It functions as all the other ACL commands
+do by permitting users running restricted consoles to specify a
+{\bf Plugin Options} that overrides the one specified in the Job
+definition. Without this directive restricted consoles may not modify
+the Plugin Options.
+
+\subsection{Plugin = \lt{}plugin-command-string\gt{}}
+\index[general]{Plugin}
+The {\bf Plugin} directive is specified in the Include section of
+a FileSet resource where you put your {\bf File = xxx} directives.
+For example:
+
+\begin{verbatim}
+ FileSet {
+ Name = "MyFileSet"
+ Include {
+ Options {
+ signature = MD5
+ }
+ File = /home
+ Plugin = "bpipe:..."
+ }
+ }
+\end{verbatim}
+
+In the above example, when the File daemon is processing the directives
+in the Include section, it will first backup all the files in {\bf /home}
+then it will load the plugin named {\bf bpipe} (actually bpipe-dir.so) from
+the Plugin Directory. The syntax and semantics of the Plugin directive
+require the first part of the string up to the colon (:) to be the name
+of the plugin. Everything after the first colon is ignored by the File daemon but
+is passed to the plugin. Thus the plugin writer may define the meaning of the
+rest of the string as he wishes.
+
+Please see the next section for information about the {\bf bpipe} Bacula
+plugin.
+
+\section{The bpipe Plugin}
+\index[general]{The bpipe Plugin}
+The {\bf bpipe} plugin is provided in the directory src/plugins/fd/bpipe-fd.c of
+the Bacula source distribution. When the plugin is compiled and linking into
+the resulting dynamic shared object (DSO), it will have the name {\bf bpipe-fd.so}.
+
+The purpose of the plugin is to provide an interface to any system program for
+backup and restore. As specified above the {\bf bpipe} plugin is specified in
+the Include section of your Job's FileSet resource. The full syntax of the
+plugin directive as interpreted by the {\bf bpipe} plugin (each plugin is free
+to specify the sytax as it wishes) is:
+
+\begin{verbatim}
+ Plugin = "<field1>:<field2>:<field3>:<field4>"
+\end{verbatim}
+
+where
+\begin{description}
+\item {\bf field1} is the name of the plugin with the trailing {\bf -fd.so}
+stripped off, so in this case, we would put {\bf bpipe} in this field.
+
+\item {\bf field2} specifies the namespace, which for {\bf bpipe} is the
+pseudo path and filename under which the backup will be saved. This pseudo
+path and filename will be seen by the user in the restore file tree.
+For example, if the value is {\bf /MYSQL/regress.sql}, the data
+backed up by the plugin will be put under that "pseudo" path and filename.
+You must be careful to choose a naming convention that is unique to avoid
+a conflict with a path and filename that actually exists on your system.
+
+\item {\bf field3} for the {\bf bpipe} plugin
+specifies the "reader" program that is called by the plugin during
+backup to read the data. {\bf bpipe} will call this program by doing a
+{\bf popen} on it.
+
+\item {\bf field4} for the {\bf bpipe} plugin
+specifies the "writer" program that is called by the plugin during
+restore to write the data back to the filesystem.
+\end{description}
+
+Putting it all together, the full plugin directive line might look
+like the following:
+
+\begin{verbatim}
+Plugin = "bpipe:/MYSQL/regress.sql:mysqldump -f
+ --opt --databases bacula:mysql"
+\end{verbatim}
+
+The directive has been split into two lines, but within the {\bf bacula-dir.conf} file
+would be written on a single line.
+
+This causes the File daemon to call the {\bf bpipe} plugin, which will write
+its data into the "pseudo" file {\bf /MYSQL/regress.sql} by calling the
+program {\bf mysqldump -f --opt --database bacula} to read the data during
+backup. The mysqldump command outputs all the data for the database named
+{\bf bacula}, which will be read by the plugin and stored in the backup.
+During restore, the data that was backed up will be sent to the program
+specified in the last field, which in this case is {\bf mysql}. When
+{\bf mysql} is called, it will read the data sent to it by the plugn
+then write it back to the same database from which it came ({\bf bacula}
+in this case).
+
+The {\bf bpipe} plugin is a generic pipe program, that simply transmits
+the data from a specified program to Bacula for backup, and then from Bacula to
+a specified program for restore.
+
+By using different command lines to {\bf bpipe},
+you can backup any kind of data (ASCII or binary) depending
+on the program called.
+
+\section{Microsoft Exchange Server 2003/2007 Plugin}
+\index[general]{Microsoft Exchange Server 2003/2007 Plugin}
+\subsection{Background}
+The Exchange plugin was made possible by a funded development project
+between Equiinet Ltd -- www.equiinet.com (many thanks) and Bacula Systems.
+The code for the plugin was written by James Harper, and the Bacula core
+code by Kern Sibbald. All the code for this funded development has become
+part of the Bacula project. Thanks to everyone who made it happen.
+
+\subsection{Concepts}
+Although it is possible to backup Exchange using Bacula VSS the Exchange
+plugin adds a good deal of functionality, because while Bacula VSS
+completes a full backup (snapshot) of Exchange, it does
+not support Incremental or Differential backups, restoring is more
+complicated, and a single database restore is not possible.
+
+Microsoft Exchange organises its storage into Storage Groups with
+Databases inside them. A default installation of Exchange will have a
+single Storage Group called 'First Storage Group', with two Databases
+inside it, "Mailbox Store (SERVER NAME)" and
+"Public Folder Store (SERVER NAME)",
+which hold user email and public folders respectively.
+
+In the default configuration, Exchange logs everything that happens to
+log files, such that if you have a backup, and all the log files since,
+you can restore to the present time. Each Storage Group has its own set
+of log files and operates independently of any other Storage Groups. At
+the Storage Group level, the logging can be turned off by enabling a
+function called "Enable circular logging". At this time the Exchange
+plugin will not function if this option is enabled.
+
+The plugin allows backing up of entire storage groups, and the restoring
+of entire storage groups or individual databases. Backing up and
+restoring at the individual mailbox or email item is not supported but
+can be simulated by use of the "Recovery" Storage Group (see below).
+
+\subsection{Installing}
+The Exchange plugin requires a DLL that is shipped with Microsoft
+Exchanger Server called {\bf esebcli2.dll}. Assuming Exchange is installed
+correctly the Exchange plugin should find this automatically and run
+without any additional installation.
+
+If the DLL can not be found automatically it will need to be copied into
+the Bacula installation
+directory (eg C:\verb+\+Program Files\verb+\+Bacula\verb+\+bin). The Exchange API DLL is
+named esebcli2.dll and is found in C:\verb+\+Program Files\verb+\+Exchsrvr\verb+\+bin on a
+default Exchange installation.
+
+\subsection{Backup up}
+To back up an Exchange server the Fileset definition must contain at
+least {\bf Plugin = "exchange:/@EXCHANGE/Microsoft Information Store"} for
+the backup to work correctly. The 'exchange:' bit tells Bacula to look
+for the exchange plugin, the '@EXCHANGE' bit makes sure all the backed
+up files are prefixed with something that isn't going to share a name
+with something outside the plugin, and the 'Microsoft Information Store'
+bit is required also. It is also possible to add the name of a storage
+group to the "Plugin =" line, eg \\
+{\bf Plugin = "exchange:/@EXCHANGE/Microsoft Information Store/First Storage Group"} \\
+if you want only a single storage group backed up.
+
+Additionally, you can suffix the 'Plugin =' directive with
+":notrunconfull" which will tell the plugin not to truncate the Exchange
+database at the end of a full backup.
+
+An Incremental or Differential backup will backup only the database logs
+for each Storage Group by inspecting the "modified date" on each
+physical log file. Because of the way the Exchange API works, the last
+logfile backed up on each backup will always be backed up by the next
+Incremental or Differential backup too. This adds 5MB to each
+Incremental or Differential backup size but otherwise does not cause any
+problems.
+
+By default, a normal VSS fileset containing all the drive letters will
+also back up the Exchange databases using VSS. This will interfere with
+the plugin and Exchange's shared ideas of when the last full backup was
+done, and may also truncate log files incorrectly. It is important,
+therefore, that the Exchange database files be excluded from the backup,
+although the folders the files are in should be included, or they will
+have to be recreated manually if a baremetal restore is done.
+
+\begin{verbatim}
+FileSet {
+ Include {
+ File = C:/Program Files/Exchsrvr/mdbdata
+ Plugin = "exchange:..."
+ }
+ Exclude {
+ File = C:/Program Files/Exchsrvr/mdbdata/E00.chk
+ File = C:/Program Files/Exchsrvr/mdbdata/E00.log
+ File = C:/Program Files/Exchsrvr/mdbdata/E000000F.log
+ File = C:/Program Files/Exchsrvr/mdbdata/E0000010.log
+ File = C:/Program Files/Exchsrvr/mdbdata/E0000011.log
+ File = C:/Program Files/Exchsrvr/mdbdata/E00tmp.log
+ File = C:/Program Files/Exchsrvr/mdbdata/priv1.edb
+ }
+}
+\end{verbatim}
+
+The advantage of excluding the above files is that you can significantly
+reduce the size of your backup since all the important Exchange files
+will be properly saved by the Plugin.
+
+
+\subsection{Restoring}
+The restore operation is much the same as a normal Bacula restore, with
+the following provisos:
+
+\begin{itemize}
+\item The {\bf Where} restore option must not be specified
+\item Each Database directory must be marked as a whole. You cannot just
+ select (say) the .edb file and not the others.
+\item If a Storage Group is restored, the directory of the Storage Group
+ must be marked too.
+\item It is possible to restore only a subset of the available log files,
+ but they {\bf must} be contiguous. Exchange will fail to restore correctly
+ if a log file is missing from the sequence of log files
+\item Each database to be restored must be dismounted and marked as "Can be
+ overwritten by restore"
+\item If an entire Storage Group is to be restored (eg all databases and
+ logs in the Storage Group), then it is best to manually delete the
+ database files from the server (eg C:\verb+\+Program Files\verb+\+Exchsrvr\verb+\+mdbdata\verb+\+*)
+ as Exchange can get confused by stray log files lying around.
+\end{itemize}
+
+\subsection{Restoring to the Recovery Storage Group}
+The concept of the Recovery Storage Group is well documented by
+Microsoft
+\elink{http://support.microsoft.com/kb/824126}{http://support.microsoft.com/kb/824126},
+but to briefly summarize...
+
+Microsoft Exchange allows the creation of an additional Storage Group
+called the Recovery Storage Group, which is used to restore an older
+copy of a database (e.g. before a mailbox was deleted) into without
+messing with the current live data. This is required as the Standard and
+Small Business Server versions of Exchange can not ordinarily have more
+than one Storage Group.
+
+To create the Recovery Storage Group, drill down to the Server in Exchange
+System Manager, right click, and select
+{\bf "New -> Recovery Storage Group..."}. Accept or change the file
+locations and click OK. On the Recovery Storage Group, right click and
+select {\bf "Add Database to Recover..."} and select the database you will
+be restoring.
+
+Restore only the single database nominated as the database in the
+Recovery Storage Group. Exchange will redirect the restore to the
+Recovery Storage Group automatically.
+Then run the restore.
+
+\subsection{Restoring on Microsoft Server 2007}
+Apparently the {\bf Exmerge} program no longer exists in Microsoft Server
+2007, and henc you use a new proceedure for recovering a single mail box.
+This procedure is ducomented by Microsoft at:
+\elink{http://technet.microsoft.com/en-us/library/aa997694.aspx}{http://technet.microsoft.com/en-us/library/aa997694.aspx},
+and involves using the {\bf Restore-Mailbox} and {\bf
+Get-MailboxStatistics} shell commands.
+
+\subsection{Caveats}
+This plugin is still being developed, so you should consider it
+currently in BETA test, and thus use in a production environment
+should be done only after very careful testing.
+
+When doing a full backup, the Exchange database logs are truncated by
+Exchange as soon as the plugin has completed the backup. If the data
+never makes it to the backup medium (eg because of spooling) then the
+logs will still be truncated, but they will also not have been backed
+up. A solution to this is being worked on. You will have to schedule a
+new Full backup to ensure that your next backups will be usable.
+
+The "Enable Circular Logging" option cannot be enabled or the plugin
+will fail.
+
+Exchange insists that a successful Full backup must have taken place if
+an Incremental or Differential backup is desired, and the plugin will
+fail if this is not the case. If a restore is done, Exchange will
+require that a Full backup be done before an Incremental or Differential
+backup is done.
+
+The plugin will most likely not work well if another backup application
+(eg NTBACKUP) is backing up the Exchange database, especially if the
+other backup application is truncating the log files.
+
+The Exchange plugin has not been tested with the {\bf Accurate} option, so
+we recommend either carefully testing or that you avoid this option for
+the current time.
+
+The Exchange plugin is not called during processing the bconsole {\bf
+estimate} command, and so anything that would be backed up by the plugin
+will not be added to the estimate total that is displayed.
+
+
+\section{libdbi Framework}
+\index[general]{libdbi Framework}
+As a general guideline, Bacula has support for a few catalog database drivers
+(MySQL, PostgreSQL, SQLite)
+coded natively by the Bacula team. With the libdbi implementation, which is a
+Bacula driver that uses libdbi to access the catalog, we have an open field to
+use many different kinds database engines following the needs of users.
+
+The according to libdbi (http://libdbi.sourceforge.net/) project: libdbi
+implements a database-independent abstraction layer in C, similar to the
+DBI/DBD layer in Perl. Writing one generic set of code, programmers can
+leverage the power of multiple databases and multiple simultaneous database
+connections by using this framework.
+
+Currently the libdbi driver in Bacula project only supports the same drivers
+natively coded in Bacula. However the libdbi project has support for many
+others database engines. You can view the list at
+http://libdbi-drivers.sourceforge.net/. In the future all those drivers can be
+supported by Bacula, however, they must be tested properly by the Bacula team.
+
+Some of benefits of using libdbi are:
+\begin{itemize}
+\item The possibility to use proprietary databases engines in which your
+ proprietary licenses prevent the Bacula team from developing the driver.
+ \item The possibility to use the drivers written for the libdbi project.
+ \item The possibility to use other database engines without recompiling Bacula
+ to use them. Just change one line in bacula-dir.conf
+ \item Abstract Database access, this is, unique point to code and profiling
+ catalog database access.
+ \end{itemize}
+
+ The following drivers have been tested:
+ \begin{itemize}
+ \item PostgreSQL, with and without batch insert
+ \item Mysql, with and without batch insert
+ \item SQLite
+ \item SQLite3
+ \end{itemize}
+
+ In the future, we will test and approve to use others databases engines
+ (proprietary or not) like DB2, Oracle, Microsoft SQL.
+
+ To compile Bacula to support libdbi we need to configure the code with the
+ --with-dbi and --with-dbi-driver=[database] ./configure options, where
+ [database] is the database engine to be used with Bacula (of course we can
+ change the driver in file bacula-dir.conf, see below). We must configure the
+ access port of the database engine with the option --with-db-port, because the
+ libdbi framework doesn't know the default access port of each database.
+
+The next phase is checking (or configuring) the bacula-dir.conf, example:
+\begin{verbatim}
+Catalog {
+ Name = MyCatalog
+ dbdriver = dbi:mysql; dbaddress = 127.0.0.1; dbport = 3306
+ dbname = regress; user = regress; password = ""
+}
+\end{verbatim}
+
+The parameter {\bf dbdriver} indicates that we will use the driver dbi with a
+mysql database. Currently the drivers supported by Bacula are: postgresql,
+mysql, sqlite, sqlite3; these are the names that may be added to string "dbi:".
+
+The following limitations apply when Bacula is set to use the libdbi framework:
+ - Not tested on the Win32 platform
+ - A little performance is lost if comparing with native database driver.
+ The reason is bound with the database driver provided by libdbi and the
+ simple fact that one more layer of code was added.
+
+It is important to remember, when compiling Bacula with libdbi, the
+following packages are needed:
+ \begin{itemize}
+ \item libdbi version 1.0.0, http://libdbi.sourceforge.net/
+ \item libdbi-drivers 1.0.0, http://libdbi-drivers.sourceforge.net/
+ \end{itemize}
+
+ You can download them and compile them on your system or install the packages
+ from your OS distribution.
+
+\section{Console Command Additions and Enhancements}
+\index[general]{Console Additions}
+
+\subsection{Display Autochanger Content}
+\index[general]{StatusSlots}
+
+The {\bf status slots storage=\lt{}storage-name\gt{}} command displays
+autochanger content.
+
+\footnotesize
+\begin{verbatim}
+ Slot | Volume Name | Status | Media Type | Pool |
+------+---------------+----------+-------------------+------------|
+ 1 | 00001 | Append | DiskChangerMedia | Default |
+ 2 | 00002 | Append | DiskChangerMedia | Default |
+ 3*| 00003 | Append | DiskChangerMedia | Scratch |
+ 4 | | | | |
+\end{verbatim}
+\normalsize
+
+If you an asterisk ({\bf *}) appears after the slot number, you must run an
+{\bf update slots} command to synchronize autochanger content with your
+catalog.
+
+\subsection{list joblog job=xxx or jobid=nnn}
+\index[general]{list joblog}
+A new list command has been added that allows you to list the contents
+of the Job Log stored in the catalog for either a Job Name (fully qualified)
+or for a particular JobId. The {\bf llist} command will include a line with
+the time and date of the entry.
+
+Note for the catalog to have Job Log entries, you must have a directive
+such as:
+
+\begin{verbatim}
+ catalog = all
+\end{verbatim}
+
+In your Director's {\bf Messages} resource.
+
+\subsection{Use separator for multiple commands}
+\index[general]{Command Separator}
+ When using bconsole with readline, you can set the command separator with
+ \textbf{@separator} command to one
+ of those characters to write commands who require multiple input in one line.
+\begin{verbatim}
+ !$%&'()*+,-/:;<>?[]^`{|}~
+\end{verbatim}
+
+\subsection{Deleting Volumes}
+The delete volume bconsole command has been modified to
+require an asterisk (*) in front of a MediaId otherwise the
+value you enter is a taken to be a Volume name. This is so that
+users may delete numeric Volume names. The previous Bacula versions
+assumed that all input that started with a number was a MediaId.
+
+This new behavior is indicated in the prompt if you read it
+carefully.
+
+\section{Bare Metal Recovery}
+The old bare metal recovery project is essentially dead. One
+of the main features of it was that it would build a recovery
+CD based on the kernel on your system. The problem was that
+every distribution has a different boot procedure and different
+scripts, and worse yet, the boot procedures and scripts change
+from one distribution to another. This meant that maintaining
+(keeping up with the changes) the rescue CD was too much work.
+
+To replace it, a new bare metal recovery USB boot stick has been developed
+by Bacula Systems. This technology involves remastering a Ubuntu LiveCD to
+boot from a USB key.
+
+Advantages:
+\begin{enumerate}
+\item Recovery can be done from within graphical environment.
+\item Recovery can be done in a shell.
+\item Ubuntu boots on a large number of Linux systems.
+\item The process of updating the system and adding new
+ packages is not too difficult.
+\item The USB key can easily be upgraded to newer Ubuntu versions.
+\item The USB key has writable partitions for modifications to
+ the OS and for modification to your home directory.
+\item You can add new files/directories to the USB key very easily.
+\item You can save the environment from multiple machines on
+ one USB key.
+\item Bacula Systems is funding its ongoing development.
+\end{enumerate}
+
+The disadvantages are:
+\begin{enumerate}
+\item The USB key is usable but currently under development.
+\item Not everyone may be familiar with Ubuntu (no worse
+ than using Knoppix)
+\item Some older OSes cannot be booted from USB. This can
+ be resolved by first booting a Ubuntu LiveCD then plugging
+ in the USB key.
+\item Currently the documentation is sketchy and not yet added
+ to the main manual. See below ...

+\section{Miscellaneous}
+\index[general]{Misc New Features}
+
+\subsection{Allow Mixed Priority = \lt{}yes|no\gt{}}
+\index[general]{Allow Mixed Priority}
+ This directive is only implemented in version 2.5 and later. When
+ set to {\bf yes} (default {\bf no}), this job may run even if lower
+ priority jobs are already running. This means a high priority job
+ will not have to wait for other jobs to finish before starting.
+ The scheduler will only mix priorities when all running jobs have
+ this set to true.
+
+ Note that only higher priority jobs will start early. Suppose the
+ director will allow two concurrent jobs, and that two jobs with
+ priority 10 are running, with two more in the queue. If a job with
+ priority 5 is added to the queue, it will be run as soon as one of
+ the running jobs finishes. However, new priority 10 jobs will not
+ be run until the priority 5 job has finished.
+
+\subsection{Bootstrap File Directive -- FileRegex}
+\index[general]{Bootstrap File Directive}
+ {\bf FileRegex} is a new command that can be added to the bootstrap
+ (.bsr) file. The value is a regular expression. When specified, only
+ matching filenames will be restored.
+
+ During a restore, if all File records are pruned from the catalog
+ for a Job, normally Bacula can restore only all files saved. That
+ is there is no way using the catalog to select individual files.
+ With this new feature, Bacula will ask if you want to specify a Regex
+ expression for extracting only a part of the full backup.
+
+\begin{verbatim}
+ Building directory tree for JobId(s) 1,3 ...
+ There were no files inserted into the tree, so file selection
+ is not possible.Most likely your retention policy pruned the files
+
+ Do you want to restore all the files? (yes|no): no
+
+ Regexp matching files to restore? (empty to abort): /tmp/regress/(bin|tests)/
+ Bootstrap records written to /tmp/regress/working/zog4-dir.restore.1.bsr
+\end{verbatim}
+
+\subsection{Bootstrap File Optimization Changes}
+In order to permit proper seeking on disk files, we have extended the bootstrap
+file format to include a {\bf VolStartAddr} and {\bf VolEndAddr} records. Each
+takes a 64 bit unsigned integer range (i.e. nnn-mmm) which defines the start
+address range and end address range respectively. These two directives replace
+the {\bf VolStartFile}, {\bf VolEndFile}, {\bf VolStartBlock} and {\bf
+ VolEndBlock} directives. Bootstrap files containing the old directives will
+still work, but will not properly take advantage of proper disk seeking, and
+may read completely to the end of a disk volume during a restore. With the new
+format (automatically generated by the new Director), restores will seek
+properly and stop reading the volume when all the files have been restored.
+
+\subsection{Solaris ZFS/NFSv4 ACLs}
+This is an upgrade of the previous Solaris ACL backup code
+to the new library format, which will backup both the old
+POSIX(UFS) ACLs as well as the ZFS ACLs.
+
+The new code can also restore POSIX(UFS) ACLs to a ZFS filesystem
+(it will translate the POSIX(UFS)) ACL into a ZFS/NFSv4 one) it can also
+be used to transfer from UFS to ZFS filesystems.
+
+
+\subsection{Virtual Tape Emulation}
+\index[general]{Virtual Tape Emulation}
+We now have a Virtual Tape emulator that allows us to run though 99.9\% of
+the tape code but actually reading and writing to a disk file. Used with the
+\textbf{disk-changer} script, you can now emulate an autochanger with 10 drives
+and 700 slots. This feature is most useful in testing. It is enabled
+by using {\bf Device Type = vtape} in the Storage daemon's Device
+directive. This feature is only implemented on Linux machines and should not be
+used for production.
+
+\subsection{Bat Enhancements}
+\index[general]{Bat Enhancements}
+Bat (the Bacula Administration Tool) GUI program has been significantly
+enhanced and stabilized. In particular, there are new table based status
+commands; it can now be easily localized using Qt4 Linguist.
+
+The Bat communications protocol has been significantly enhanced to improve
+GUI handling. Note, you {\bf must} use a the bat that is distributed with
+the Director you are using otherwise the communications protocol will not
+work.
+
+\subsection{RunScript Enhancements}
+\index[general]{RunScript Enhancements}
+The {\bf RunScript} resource has been enhanced to permit multiple
+commands per RunScript. Simply specify multiple {\bf Command} directives
+in your RunScript.
+
+\begin{verbatim}
+Job {
+ Name = aJob
+ RunScript {
+ Command = "/bin/echo test"
+ Command = "/bin/echo an other test"
+ Command = "/bin/echo 3 commands in the same runscript"
+ RunsWhen = Before
+ }
+ ...
+}
+\end{verbatim}
+
+A new Client RunScript {\bf RunsWhen} keyword of {\bf AfterVSS} has been
+implemented, which runs the command after the Volume Shadow Copy has been made.
+
+Console commands can be specified within a RunScript by using:
+{\bf Console = \lt{}command\gt{}}, however, this command has not been
+carefully tested and debugged and is known to easily crash the Director.
+We would appreciate feedback. Due to the recursive nature of this command, we
+may remove it before the final release.
+
+\subsection{Status Enhancements}
+\index[general]{Status Enhancements}
+The bconsole {\bf status dir} output has been enhanced to indicate
+Storage daemon job spooling and despooling activity.
+
+\subsection{Connect Timeout}
+\index[general]{Connect Timeout}
+The default connect timeout to the File
+daemon has been set to 3 minutes. Previously it was 30 minutes.
+
+\subsection{ftruncate for NFS Volumes}
+\index[general]{ftruncate for NFS Volumes}
+If you write to a Volume mounted by NFS (say on a local file server),
+in previous Bacula versions, when the Volume was recycled, it was not
+properly truncated because NFS does not implement ftruncate (file
+truncate). This is now corrected in the new version because we have
+written code (actually a kind user) that deletes and recreates the Volume,
+thus accomplishing the same thing as a truncate.
+
+\subsection{Support for Ubuntu}
+The new version of Bacula now recognizes the Ubuntu (and Kubuntu)
+version of Linux, and thus now provides correct autostart routines.
+Since Ubuntu officially supports Bacula, you can also obtain any
+recent release of Bacula from the Ubuntu repositories.
+
+\subsection{Recycle Pool = \lt{}pool-name\gt{}}
+\index[general]{Recycle Pool}
+The new \textbf{RecyclePool} directive defines to which pool the Volume will
+be placed (moved) when it is recycled. Without this directive, a Volume will
+remain in the same pool when it is recycled. With this directive, it can be
+moved automatically to any existing pool during a recycle. This directive is
+probably most useful when defined in the Scratch pool, so that volumes will
+be recycled back into the Scratch pool.
+
+\subsection{FD Version}
+\index[general]{FD Version}
+The File daemon to Director protocol now includes a version
+number, which although there is no visible change for users,
+will help us in future versions automatically determine
+if a File daemon is not compatible.
+
+\subsection{Max Run Sched Time = \lt{}time-period-in-seconds\gt{}}
+\index[general]{Max Run Sched Time}
+The time specifies the maximum allowed time that a job may run, counted from
+when the job was scheduled. This can be useful to prevent jobs from running
+during working hours. We can see it like \texttt{Max Start Delay + Max Run
+ Time}.
+
+\subsection{Max Wait Time = \lt{}time-period-in-seconds\gt{}}
+\index[general]{Max Wait Time}
+Previous \textbf{MaxWaitTime} directives aren't working as expected, instead
+of checking the maximum allowed time that a job may block for a resource,
+those directives worked like \textbf{MaxRunTime}. Some users are reporting to
+use \textbf{Incr/Diff/Full Max Wait Time} to control the maximum run time of
+their job depending on the level. Now, they have to use
+\textbf{Incr/Diff/Full Max Run Time}. \textbf{Incr/Diff/Full Max Wait Time}
+directives are now deprecated.
+
+\subsection{Incremental|Differential Max Wait Time = \lt{}time-period-in-seconds\gt{}}
+\index[general]{Incremental Max Wait Time}
+\index[general]{Differential Max Wait Time}
+
+These directives have been deprecated in favor of
+\texttt{Incremental|Differential Max Run Time}.
+
+\subsection{Max Run Time directives}
+\index[general]{Max Run Time directives}
+Using \textbf{Full/Diff/Incr Max Run Time}, it's now possible to specify the
+maximum allowed time that a job can run depending on the level.
+
+\addcontentsline{lof}{figure}{Job time control directives}
+\includegraphics{\idir different_time.eps}
+
+\subsection{Statistics Enhancements}
+\index[general]{Statistics Enhancements}
+If you (or probably your boss) want to have statistics on your backups to
+provide some \textit{Service Level Agreement} indicators, you could use a few
+SQL queries on the Job table to report how many:
+
+\begin{itemize}
+\item jobs have run
+\item jobs have been successful
+\item files have been backed up
+\item ...
+\end{itemize}
+
+However, these statistics are accurate only if your job retention is greater
+than your statistics period. Ie, if jobs are purged from the catalog, you won't
+be able to use them.
+
+Now, you can use the \textbf{update stats [days=num]} console command to fill
+the JobHistory table with new Job records. If you want to be sure to take in
+account only \textbf{good jobs}, ie if one of your important job has failed but
+you have fixed the problem and restarted it on time, you probably want to
+delete the first \textit{bad} job record and keep only the successful one. For
+that simply let your staff do the job, and update JobHistory table after two or
+three days depending on your organization using the \textbf{[days=num]} option.
+
+These statistics records aren't used for restoring, but mainly for
+capacity planning, billings, etc.
+
+The Bweb interface provides a statistics module that can use this feature. You
+can also use tools like Talend or extract information by yourself.
+
+The \textbf{Statistics Retention = \lt{}time\gt{}} director directive defines
+the length of time that Bacula will keep statistics job records in the Catalog
+database after the Job End time. (In \texttt{JobHistory} table) When this time
+period expires, and if user runs \texttt{prune stats} command, Bacula will
+prune (remove) Job records that are older than the specified period.
+
+You can use the following Job resource in your nightly \textbf{BackupCatalog}
+job to maintain statistics.
+\begin{verbatim}
+Job {
+ Name = BackupCatalog
+ ...
+ RunScript {
+ Console = "update stats days=3"
+ Console = "prune stats yes"
+ RunsWhen = After
+ RunsOnClient = no
+ }
+}
+\end{verbatim}
+
+\subsection{ScratchPool = \lt{}pool-resource-name\gt{}}
+\index[general]{ScratchPool}
+This directive permits to specify a specific \textsl{Scratch} pool for the
+current pool. This is useful when using multiple storage sharing the same
+mediatype or when you want to dedicate volumes to a particular set of pool.
+
+\subsection{Enhanced Attribute Despooling}
+\index[general]{Attribute Despooling}
+If the storage daemon and the Director are on the same machine, the spool file
+that contains attributes is read directly by the Director instead of being
+transmitted across the network. That should reduce load and speedup insertion.
+
+\subsection{SpoolSize = \lt{}size-specification-in-bytes\gt{}}
+\index[general]{SpoolSize}
+A new Job directive permits to specify the spool size per job. This is used
+in advanced job tunning. {\bf SpoolSize={\it bytes}}
+
+\subsection{MaxConsoleConnections = \lt{}number\gt{}}
+\index[general]{MaxConsoleConnections}
+A new director directive permits to specify the maximum number of Console
+Connections that could run concurrently. The default is set to 20, but you may
+set it to a larger number.
+
+\subsection{VerId = \lt{}string\gt{}}
+\index[general]{VerId}
+A new director directive permits to specify a personnal identifier that will be
+displayed in the \texttt{version} command.
+
+\subsection{dbcheck enhancements}
+\index[general]{dbcheck enhancements}
+If you are using Mysql, dbcheck will now ask you if you want to create
+temporary indexes to speed up orphaned Path and Filename elimination.
+
+A new \texttt{-B} option allows you to print catalog information in a simple
+text based format. This is useful to backup it in a secure way.
+
+\begin{verbatim}
+ $ dbcheck -B
+ catalog=MyCatalog
+ db_type=SQLite
+ db_name=regress
+ db_driver=
+ db_user=regress
+ db_password=
+ db_address=
+ db_port=0
+ db_socket=
+\end{verbatim} %$
+
+You can now specify the database connection port in the command line.
+
+\subsection{{-}{-}docdir configure option}
+\index[general]{{-}{-}docdir configure option}
+You can use {-}{-}docdir= on the ./configure command to
+specify the directory where you want Bacula to install the
+LICENSE, ReleaseNotes, ChangeLog, ... files. The default is
+{\bf /usr/share/doc/bacula}.
+
+\subsection{{-}{-}htmldir configure option}
+\index[general]{{-}{-}htmldir configure option}
+You can use {-}{-}htmldir= on the ./configure command to
+specify the directory where you want Bacula to install the bat html help
+files. The default is {\bf /usr/share/doc/bacula/html}
+
+\subsection{{-}{-}with-plugindir configure option}
+\index[general]{{-}{-}plugindir configure option}
+You can use {-}{-}plugindir= on the ./configure command to
+specify the directory where you want Bacula to install
+the plugins (currently only bpipe-fd). The default is
+/usr/lib.
--- /dev/null

+
+\chapter{Bacula FD Plugin API}
+To write a Bacula plugin, you create a dynamic shared object program (or dll on
+Win32) with a particular name and two exported entry points, place it in the
+{\bf Plugins Directory}, which is defined in the {\bf bacula-fd.conf} file in
+the {\bf Client} resource, and when the FD starts, it will load all the plugins
+that end with {\bf -fd.so} (or {\bf -fd.dll} on Win32) found in that directory.
+
+\section{Normal vs Command Plugins}
+In general, there are two ways that plugins are called. The first way, is when
+a particular event is detected in Bacula, it will transfer control to each
+plugin that is loaded in turn informing the plugin of the event. This is very
+similar to how a {\bf RunScript} works, and the events are very similar. Once
+the plugin gets control, it can interact with Bacula by getting and setting
+Bacula variables. In this way, it behaves much like a RunScript. Currently
+very few Bacula variables are defined, but they will be implemented as the need
+arrises, and it is very extensible.
+
+We plan to have plugins register to receive events that they normally would
+not receive, such as an event for each file examined for backup or restore.
+This feature is not yet implemented.
+
+The second type of plugin, which is more useful and fully implemented in the
+current version is what we call a command plugin. As with all plugins, it gets
+notified of important events as noted above (details described below), but in
+addition, this kind of plugin can accept a command line, which is a:
+
+\begin{verbatim}
+ Plugin = <command-string>
+\end{verbatim}
+
+directive that is placed in the Include section of a FileSet and is very
+similar to the "File = " directive. When this Plugin directive is encountered
+by Bacula during backup, it passes the "command" part of the Plugin directive
+only to the plugin that is explicitly named in the first field of that command
+string. This allows that plugin to backup any file or files on the system that
+it wants. It can even create "virtual files" in the catalog that contain data
+to be restored but do not necessarily correspond to actual files on the
+filesystem.
+
+The important features of the command plugin entry points are:
+\begin{itemize}
+ \item It is triggered by a "Plugin =" directive in the FileSet
+ \item Only a single plugin is called that is named on the "Plugin =" directive.
+ \item The full command string after the "Plugin =" is passed to the plugin
+ so that it can be told what to backup/restore.
+\end{itemize}
+
+
+\section{Loading Plugins}
+Once the File daemon loads the plugins, it asks the OS for the
+two entry points (loadPlugin and unloadPlugin) then calls the
+{\bf loadPlugin} entry point (see below).
+
+Bacula passes information to the plugin through this call and it gets
+back information that it needs to use the plugin. Later, Bacula
+ will call particular functions that are defined by the
+{\bf loadPlugin} interface.
+
+When Bacula is finished with the plugin
+(when Bacula is going to exit), it will call the {\bf unloadPlugin}
+entry point.
+
+The two entry points are:
+
+\begin{verbatim}
+bRC loadPlugin(bInfo *lbinfo, bFuncs *lbfuncs, pInfo **pinfo, pFuncs **pfuncs)
+
+and
+
+bRC unloadPlugin()
+\end{verbatim}
+
+both these external entry points to the shared object are defined as C entry
+points to avoid name mangling complications with C++. However, the shared
+object can actually be written in any language (preferrably C or C++) providing
+that it follows C language calling conventions.
+
+The definitions for {\bf bRC} and the arguments are {\bf
+src/filed/fd-plugins.h} and so this header file needs to be included in
+your plugin. It along with {\bf src/lib/plugins.h} define basically the whole
+plugin interface. Within this header file, it includes the following
+files:
+
+\begin{verbatim}
+#include <sys/types.h>
+#include "config.h"
+#include "bc_types.h"
+#include "lib/plugins.h"
+#include <sys/stat.h>
+\end{verbatim}
+
+Aside from the {\bf bc\_types.h} and {\bf confit.h} headers, the plugin
+definition uses the minimum code from Bacula. The bc\_types.h file is required
+to ensure that the data type defintions in arguments correspond to the Bacula
+core code.
+
+The return codes are defined as:
+\begin{verbatim}
+typedef enum {
+ bRC_OK = 0, /* OK */
+ bRC_Stop = 1, /* Stop calling other plugins */
+ bRC_Error = 2, /* Some kind of error */
+ bRC_More = 3, /* More files to backup */
+} bRC;
+\end{verbatim}
+
+
+At a future point in time, we hope to make the Bacula libbac.a into a
+shared object so that the plugin can use much more of Bacula's
+infrastructure, but for this first cut, we have tried to minimize the
+dependence on Bacula.
+
+\section{loadPlugin}
+As previously mentioned, the {\bf loadPlugin} entry point in the plugin
+is called immediately after Bacula loads the plugin when the File daemon
+itself is first starting. This entry point is only called once during the
+execution of the File daemon. In calling the
+plugin, the first two arguments are information from Bacula that
+is passed to the plugin, and the last two arguments are information
+about the plugin that the plugin must return to Bacula. The call is:
+
+\begin{verbatim}
+bRC loadPlugin(bInfo *lbinfo, bFuncs *lbfuncs, pInfo **pinfo, pFuncs **pfuncs)
+\end{verbatim}
+
+and the arguments are:
+
+\begin{description}
+\item [lbinfo]
+This is information about Bacula in general. Currently, the only value
+defined in the bInfo structure is the version, which is the Bacula plugin
+interface version, currently defined as 1. The {\bf size} is set to the
+byte size of the structure. The exact definition of the bInfo structure
+as of this writing is:
+
+\begin{verbatim}
+typedef struct s_baculaInfo {
+ uint32_t size;
+ uint32_t version;
+} bInfo;
+\end{verbatim}
+
+\item [lbfuncs]
+The bFuncs structure defines the callback entry points within Bacula
+that the plugin can use register events, get Bacula values, set
+Bacula values, and send messages to the Job output or debug output.
+
+The exact definition as of this writing is:
+\begin{verbatim}
+typedef struct s_baculaFuncs {
+ uint32_t size;
+ uint32_t version;
+ bRC (*registerBaculaEvents)(bpContext *ctx, ...);
+ bRC (*getBaculaValue)(bpContext *ctx, bVariable var, void *value);
+ bRC (*setBaculaValue)(bpContext *ctx, bVariable var, void *value);
+ bRC (*JobMessage)(bpContext *ctx, const char *file, int line,
+ int type, utime_t mtime, const char *fmt, ...);
+ bRC (*DebugMessage)(bpContext *ctx, const char *file, int line,
+ int level, const char *fmt, ...);
+ void *(*baculaMalloc)(bpContext *ctx, const char *file, int line,
+ size_t size);
+ void (*baculaFree)(bpContext *ctx, const char *file, int line, void *mem);
+} bFuncs;
+\end{verbatim}
+
+We will discuss these entry points and how to use them a bit later when
+describing the plugin code.
+
+
+\item [pInfo]
+When the loadPlugin entry point is called, the plugin must initialize
+an information structure about the plugin and return a pointer to
+this structure to Bacula.
+
+The exact definition as of this writing is:
+
+\begin{verbatim}
+typedef struct s_pluginInfo {
+ uint32_t size;
+ uint32_t version;
+ const char *plugin_magic;
+ const char *plugin_license;
+ const char *plugin_author;
+ const char *plugin_date;
+ const char *plugin_version;
+ const char *plugin_description;
+} pInfo;
+\end{verbatim}
+
+Where:
+ \begin{description}
+ \item [version] is the current Bacula defined plugin interface version, currently
+ set to 1. If the interface version differs from the current version of
+ Bacula, the plugin will not be run (not yet implemented).
+ \item [plugin\_magic] is a pointer to the text string "*FDPluginData*", a
+ sort of sanity check. If this value is not specified, the plugin
+ will not be run (not yet implemented).
+ \item [plugin\_license] is a pointer to a text string that describes the
+ plugin license. Bacula will only accept compatible licenses (not yet
+ implemented).
+ \item [plugin\_author] is a pointer to the text name of the author of the program.
+ This string can be anything but is generally the author's name.
+ \item [plugin\_date] is the pointer text string containing the date of the plugin.
+ This string can be anything but is generally some human readable form of
+ the date.
+ \item [plugin\_version] is a pointer to a text string containing the version of
+ the plugin. The contents are determined by the plugin writer.
+ \item [plugin\_description] is a pointer to a string describing what the
+ plugin does. The contents are determined by the plugin writer.
+ \end{description}
+
+The pInfo structure must be defined in static memory because Bacula does not
+copy it and may refer to the values at any time while the plugin is
+loaded. All values must be supplied or the plugin will not run (not yet
+implemented). All text strings must be either ASCII or UTF-8 strings that
+are terminated with a zero byte.
+
+\item [pFuncs]
+When the loadPlugin entry point is called, the plugin must initialize
+an entry point structure about the plugin and return a pointer to
+this structure to Bacula. This structure contains pointer to each
+of the entry points that the plugin must provide for Bacula. When
+Bacula is actually running the plugin, it will call the defined
+entry points at particular times. All entry points must be defined.
+
+The pFuncs structure must be defined in static memory because Bacula does not
+copy it and may refer to the values at any time while the plugin is
+loaded.
+
+The exact definition as of this writing is:
+
+\begin{verbatim}
+typedef struct s_pluginFuncs {
+ uint32_t size;
+ uint32_t version;
+ bRC (*newPlugin)(bpContext *ctx);
+ bRC (*freePlugin)(bpContext *ctx);
+ bRC (*getPluginValue)(bpContext *ctx, pVariable var, void *value);
+ bRC (*setPluginValue)(bpContext *ctx, pVariable var, void *value);
+ bRC (*handlePluginEvent)(bpContext *ctx, bEvent *event, void *value);
+ bRC (*startBackupFile)(bpContext *ctx, struct save_pkt *sp);
+ bRC (*endBackupFile)(bpContext *ctx);
+ bRC (*startRestoreFile)(bpContext *ctx, const char *cmd);
+ bRC (*endRestoreFile)(bpContext *ctx);
+ bRC (*pluginIO)(bpContext *ctx, struct io_pkt *io);
+ bRC (*createFile)(bpContext *ctx, struct restore_pkt *rp);
+ bRC (*setFileAttributes)(bpContext *ctx, struct restore_pkt *rp);
+ bRC (*checkFile)(bpContext *ctx, char *fname);
+} pFuncs;
+\end{verbatim}
+
+The details of the entry points will be presented in
+separate sections below.
+
+Where:
+ \begin{description}
+ \item [size] is the byte size of the structure.
+ \item [version] is the plugin interface version currently set to 3.
+ \end{description}
+
+Sample code for loadPlugin:
+\begin{verbatim}
+ bfuncs = lbfuncs; /* set Bacula funct pointers */
+ binfo = lbinfo;
+ *pinfo = &pluginInfo; /* return pointer to our info */
+ *pfuncs = &pluginFuncs; /* return pointer to our functions */
+
+ return bRC_OK;
+\end{verbatim}
+
+where pluginInfo and pluginFuncs are statically defined structures.
+See bpipe-fd.c for details.
+
+
+
+\end{description}
+
+\section{Plugin Entry Points}
+This section will describe each of the entry points (subroutines) within
+the plugin that the plugin must provide for Bacula, when they are called
+and their arguments. As noted above, pointers to these subroutines are
+passed back to Bacula in the pFuncs structure when Bacula calls the
+loadPlugin() externally defined entry point.
+
+\subsection{newPlugin(bpContext *ctx)}
+ This is the entry point that Bacula will call
+ when a new "instance" of the plugin is created. This typically
+ happens at the beginning of a Job. If 10 Jobs are running
+ simultaneously, there will be at least 10 instances of the
+ plugin.
+
+ The bpContext structure will be passed to the plugin, and
+ during this call, if the plugin needs to have its private
+ working storage that is associated with the particular
+ instance of the plugin, it should create it from the heap
+ (malloc the memory) and store a pointer to
+ its private working storage in the {\bf pContext} variable.
+ Note: since Bacula is a multi-threaded program, you must not
+ keep any variable data in your plugin unless it is truely meant
+ to apply globally to the whole plugin. In addition, you must
+ be aware that except the first and last call to the plugin
+ (loadPlugin and unloadPlugin) all the other calls will be
+ made by threads that correspond to a Bacula job. The
+ bpContext that will be passed for each thread will remain the
+ same throughout the Job thus you can keep your privat Job specific
+ data in it ({\bf bContext}).
+
+\begin{verbatim}
+typedef struct s_bpContext {
+ void *pContext; /* Plugin private context */
+ void *bContext; /* Bacula private context */
+} bpContext;
+
+\end{verbatim}
+
+ This context pointer will be passed as the first argument to all
+ the entry points that Bacula calls within the plugin. Needless
+ to say, the plugin should not change the bContext variable, which
+ is Bacula's private context pointer for this instance (Job) of this
+ plugin.
+
+\subsection{freePlugin(bpContext *ctx)}
+This entry point is called when the
+this instance of the plugin is no longer needed (the Job is
+ending), and the plugin should release all memory it may
+have allocated for this particular instance (Job) i.e. the pContext.
+This is not the final termination
+of the plugin signaled by a call to {\bf unloadPlugin}.
+Any other instances (Job) will
+continue to run, and the entry point {\bf newPlugin} may be called
+again if other jobs start.
+
+\subsection{getPluginValue(bpContext *ctx, pVariable var, void *value)}
+Bacula will call this entry point to get
+a value from the plugin. This entry point is currently not called.
+
+\subsection{setPluginValue(bpContext *ctx, pVariable var, void *value)}
+Bacula will call this entry point to set
+a value in the plugin. This entry point is currently not called.
+
+\subsection{handlePluginEvent(bpContext *ctx, bEvent *event, void *value)}
+This entry point is called when Bacula
+encounters certain events (discussed below). This is, in fact, the
+main way that most plugins get control when a Job runs and how
+they know what is happening in the job. It can be likened to the
+{\bf RunScript} feature that calls external programs and scripts,
+and is very similar to the Bacula Python interface.
+When the plugin is called, Bacula passes it the pointer to an event
+structure (bEvent), which currently has one item, the eventType:
+
+\begin{verbatim}
+typedef struct s_bEvent {
+ uint32_t eventType;
+} bEvent;
+\end{verbatim}
+
+ which defines what event has been triggered, and for each event,
+ Bacula will pass a pointer to a value associated with that event.
+ If no value is associated with a particular event, Bacula will
+ pass a NULL pointer, so the plugin must be careful to always check
+ value pointer prior to dereferencing it.
+
+ The current list of events are:
+
+\begin{verbatim}
+typedef enum {
+ bEventJobStart = 1,
+ bEventJobEnd = 2,
+ bEventStartBackupJob = 3,
+ bEventEndBackupJob = 4,
+ bEventStartRestoreJob = 5,
+ bEventEndRestoreJob = 6,
+ bEventStartVerifyJob = 7,
+ bEventEndVerifyJob = 8,
+ bEventBackupCommand = 9,
+ bEventRestoreCommand = 10,
+ bEventLevel = 11,
+ bEventSince = 12,
+} bEventType;
+
+\end{verbatim}
+
+Most of the above are self-explanatory.
+
+\begin{description}
+ \item [bEventJobStart] is called whenever a Job starts. The value
+ passed is a pointer to a string that contains: "Jobid=nnn
+ Job=job-name". Where nnn will be replaced by the JobId and job-name
+ will be replaced by the Job name. The variable is temporary so if you
+ need the values, you must copy them.
+
+ \item [bEventJobEnd] is called whenever a Job ends. No value is passed.
+
+ \item [bEventStartBackupJob] is called when a Backup Job begins. No value
+ is passed.
+
+ \item [bEventEndBackupJob] is called when a Backup Job ends. No value is
+ passed.
+
+ \item [bEventStartRestoreJob] is called when a Restore Job starts. No value
+ is passed.
+
+ \item [bEventEndRestoreJob] is called when a Restore Job ends. No value is
+ passed.
+
+ \item [bEventStartVerifyJob] is called when a Verify Job starts. No value
+ is passed.
+
+ \item [bEventEndVerifyJob] is called when a Verify Job ends. No value
+ is passed.
+
+ \item [bEventBackupCommand] is called prior to the bEventStartBackupJob and
+ the plugin is passed the command string (everything after the equal sign
+ in "Plugin =" as the value.
+
+ Note, if you intend to backup a file, this is an important first point to
+ write code that copies the command string passed into your pContext area
+ so that you will know that a backup is being performed and you will know
+ the full contents of the "Plugin =" command (i.e. what to backup and
+ what virtual filename the user wants to call it.
+
+ \item [bEventRestoreCommand] is called prior to the bEventStartRestoreJob and
+ the plugin is passed the command string (everything after the equal sign
+ in "Plugin =" as the value.
+
+ See the notes above concerning backup and the command string. This is the
+ point at which Bacula passes you the original command string that was
+ specified during the backup, so you will want to save it in your pContext
+ area for later use when Bacula calls the plugin again.
+
+ \item [bEventLevel] is called when the level is set for a new Job. The value
+ is a 32 bit integer stored in the void*, which represents the Job Level code.
+
+ \item [bEventSince] is called when the since time is set for a new Job. The
+ value is a time\_t time at which the last job was run.
+\end{description}
+
+During each of the above calls, the plugin receives either no specific value or
+only one value, which in some cases may not be sufficient. However, knowing
+the context of the event, the plugin can call back to the Bacula entry points
+it was passed during the {\bf loadPlugin} call and get to a number of Bacula
+variables. (at the current time few Bacula variables are implemented, but it
+easily extended at a future time and as needs require).
+
+\subsection{startBackupFile(bpContext *ctx, struct save\_pkt *sp)}
+This entry point is called only if your plugin is a command plugin, and
+it is called when Bacula encounters the "Plugin = " directive in
+the Include section of the FileSet.
+Called when beginning the backup of a file. Here Bacula provides you
+with a pointer to the {\bf save\_pkt} structure and you must fill in
+this packet with the "attribute" data of the file.
+
+\begin{verbatim}
+struct save_pkt {
+ int32_t pkt_size; /* size of this packet */
+ char *fname; /* Full path and filename */
+ char *link; /* Link name if any */
+ struct stat statp; /* System stat() packet for file */
+ int32_t type; /* FT_xx for this file */
+ uint32_t flags; /* Bacula internal flags */
+ bool portable; /* set if data format is portable */
+ char *cmd; /* command */
+ int32_t pkt_end; /* end packet sentinel */
+};
+\end{verbatim}
+
+The second argument is a pointer to the {\bf save\_pkt} structure for the file
+to be backed up. The plugin is responsible for filling in all the fields
+of the {\bf save\_pkt}. If you are backing up
+a real file, then generally, the statp structure can be filled in by doing
+a {\bf stat} system call on the file.
+
+If you are backing up a database or
+something that is more complex, you might want to create a virtual file.
+That is a file that does not actually exist on the filesystem, but represents
+say an object that you are backing up. In that case, you need to ensure
+that the {\bf fname} string that you pass back is unique so that it
+does not conflict with a real file on the system, and you need to
+artifically create values in the statp packet.
+
+Example programs such as {\bf bpipe-fd.c} show how to set these fields. You
+must take care not to store pointers the stack in the pointer fields such as
+fname and link, because when you return from your function, your stack entries
+will be destroyed. The solution in that case is to malloc() and return the
+pointer to it. In order to not have memory leaks, you should store a pointer to
+all memory allocated in your pContext structure so that in subsequent calls or
+at termination, you can release it back to the system.
+
+Once the backup has begun, Bacula will call your plugin at the {\bf pluginIO}
+entry point to "read" the data to be backed up. Please see the {\bf bpipe-fd.c}
+plugin for how to do I/O.
+
+Example of filling in the save\_pkt as used in bpipe-fd.c:
+
+\begin{verbatim}
+ struct plugin_ctx *p_ctx = (struct plugin_ctx *)ctx->pContext;
+ time_t now = time(NULL);
+ sp->fname = p_ctx->fname;
+ sp->statp.st_mode = 0700 | S_IFREG;
+ sp->statp.st_ctime = now;
+ sp->statp.st_mtime = now;
+ sp->statp.st_atime = now;
+ sp->statp.st_size = -1;
+ sp->statp.st_blksize = 4096;
+ sp->statp.st_blocks = 1;
+ p_ctx->backup = true;
+ return bRC_OK;
+\end{verbatim}
+
+Note: the filename to be created has already been created from the
+command string previously sent to the plugin and is in the plugin
+context (p\_ctx->fname) and is a malloc()ed string. This example
+creates a regular file (S\_IFREG), with various fields being created.
+
+In general, the sequence of commands issued from Bacula to the plugin
+to do a backup while processing the "Plugin = " directive are:
+
+\begin{enumerate}
+ \item generate a bEventBackupCommand event to the specified plugin
+ and pass it the command string.
+ \item make a startPluginBackup call to the plugin, which
+ fills in the data needed in save\_pkt to save as the file
+ attributes and to put on the Volume and in the catalog.
+ \item call Bacula's internal save\_file() subroutine to save the specified
+ file. The plugin will then be called at pluginIO() to "open"
+ the file, and then to read the file data.
+ Note, if you are dealing with a virtual file, the "open" operation
+ is something the plugin does internally and it doesn't necessarily
+ mean opening a file on the filesystem. For example in the case of
+ the bpipe-fd.c program, it initiates a pipe to the requested program.
+ Finally when the plugin signals to Bacula that all the data was read,
+ Bacula will call the plugin with the "close" pluginIO() function.
+\end{enumerate}
+
+
+\subsection{endBackupFile(bpContext *ctx)}
+Called at the end of backing up a file for a command plugin. If the plugin's
+work is done, it should return bRC\_OK. If the plugin wishes to create another
+file and back it up, then it must return bRC\_More (not yet implemented). This
+is probably a good time to release any malloc()ed memory you used to pass back
+filenames.
+
+\subsection{startRestoreFile(bpContext *ctx, const char *cmd)}
+Called when the first record is read from the Volume that was
+previously written by the command plugin.
+
+\subsection{createFile(bpContext *ctx, struct restore\_pkt *rp)}
+Called for a command plugin to create a file during a Restore job before
+restoring the data.
+This entry point is called before any I/O is done on the file. After
+this call, Bacula will call pluginIO() to open the file for write.
+
+The data in the
+restore\_pkt is passed to the plugin and is based on the data that was
+originally given by the plugin during the backup and the current user
+restore settings (e.g. where, RegexWhere, replace). This allows the
+plugin to first create a file (if necessary) so that the data can
+be transmitted to it. The next call to the plugin will be a
+pluginIO command with a request to open the file write-only.
+
+This call must return one of the following values:
+
+\begin{verbatim}
+ enum {
+ CF_SKIP = 1, /* skip file (not newer or something) */
+ CF_ERROR, /* error creating file */
+ CF_EXTRACT, /* file created, data to extract */
+ CF_CREATED /* file created, no data to extract */
+};
+\end{verbatim}
+
+in the restore\_pkt value {\bf create\_status}. For a normal file,
+unless there is an error, you must return {\bf CF\_EXTRACT}.
+
+\begin{verbatim}
+
+struct restore_pkt {
+ int32_t pkt_size; /* size of this packet */
+ int32_t stream; /* attribute stream id */
+ int32_t data_stream; /* id of data stream to follow */
+ int32_t type; /* file type FT */
+ int32_t file_index; /* file index */
+ int32_t LinkFI; /* file index to data if hard link */
+ uid_t uid; /* userid */
+ struct stat statp; /* decoded stat packet */
+ const char *attrEx; /* extended attributes if any */
+ const char *ofname; /* output filename */
+ const char *olname; /* output link name */
+ const char *where; /* where */
+ const char *RegexWhere; /* regex where */
+ int replace; /* replace flag */
+ int create_status; /* status from createFile() */
+ int32_t pkt_end; /* end packet sentinel */
+
+};
+\end{verbatim}
+
+Typical code to create a regular file would be the following:
+
+\begin{verbatim}
+ struct plugin_ctx *p_ctx = (struct plugin_ctx *)ctx->pContext;
+ time_t now = time(NULL);
+ sp->fname = p_ctx->fname; /* set the full path/filename I want to create */
+ sp->type = FT_REG;
+ sp->statp.st_mode = 0700 | S_IFREG;
+ sp->statp.st_ctime = now;
+ sp->statp.st_mtime = now;
+ sp->statp.st_atime = now;
+ sp->statp.st_size = -1;
+ sp->statp.st_blksize = 4096;
+ sp->statp.st_blocks = 1;
+ return bRC_OK;
+\end{verbatim}
+
+This will create a virtual file. If you are creating a file that actually
+exists, you will most likely want to fill the statp packet using the
+stat() system call.
+
+Creating a directory is similar, but requires a few extra steps:
+
+\begin{verbatim}
+ struct plugin_ctx *p_ctx = (struct plugin_ctx *)ctx->pContext;
+ time_t now = time(NULL);
+ sp->fname = p_ctx->fname; /* set the full path I want to create */
+ sp->link = xxx; where xxx is p_ctx->fname with a trailing forward slash
+ sp->type = FT_DIREND
+ sp->statp.st_mode = 0700 | S_IFDIR;
+ sp->statp.st_ctime = now;
+ sp->statp.st_mtime = now;
+ sp->statp.st_atime = now;
+ sp->statp.st_size = -1;
+ sp->statp.st_blksize = 4096;
+ sp->statp.st_blocks = 1;
+ return bRC_OK;
+\end{verbatim}
+
+The link field must be set with the full cononical path name, which always
+ends with a forward slash. If you do not terminate it with a forward slash,
+you will surely have problems later.
+
+As with the example that creates a file, if you are backing up a real
+directory, you will want to do an stat() on the directory.
+
+Note, if you want the directory permissions and times to be correctly
+restored, you must create the directory {\bf after} all the file directories
+have been sent to Bacula. That allows the restore process to restore all the
+files in a directory using default directory options, then at the end, restore
+the directory permissions. If you do it the other way around, each time you
+restore a file, the OS will modify the time values for the directory entry.
+
+\subsection{setFileAttributes(bpContext *ctx, struct restore\_pkt *rp)}
+This is call not yet implemented. Called for a command plugin.
+
+See the definition of {\bf restre\_pkt} in the above section.
+
+\subsection{endRestoreFile(bpContext *ctx)}
+Called when a command plugin is done restoring a file.
+
+\subsection{pluginIO(bpContext *ctx, struct io\_pkt *io)}
+Called to do the input (backup) or output (restore) of data from or to a file
+for a command plugin. These routines simulate the Unix read(), write(), open(),
+close(), and lseek() I/O calls, and the arguments are passed in the packet and
+the return values are also placed in the packet. In addition for Win32 systems
+the plugin must return two additional values (described below).
+
+\begin{verbatim}
+ enum {
+ IO_OPEN = 1,
+ IO_READ = 2,
+ IO_WRITE = 3,
+ IO_CLOSE = 4,
+ IO_SEEK = 5
+};
+
+struct io_pkt {
+ int32_t pkt_size; /* Size of this packet */
+ int32_t func; /* Function code */
+ int32_t count; /* read/write count */
+ mode_t mode; /* permissions for created files */
+ int32_t flags; /* Open flags */
+ char *buf; /* read/write buffer */
+ const char *fname; /* open filename */
+ int32_t status; /* return status */
+ int32_t io_errno; /* errno code */
+ int32_t lerror; /* Win32 error code */
+ int32_t whence; /* lseek argument */
+ boffset_t offset; /* lseek argument */
+ bool win32; /* Win32 GetLastError returned */
+ int32_t pkt_end; /* end packet sentinel */
+};
+\end{verbatim}
+
+The particular Unix function being simulated is indicated by the {\bf func},
+which will have one of the IO\_OPEN, IO\_READ, ... codes listed above. The
+status code that would be returned from a Unix call is returned in {\bf status}
+for IO\_OPEN, IO\_CLOSE, IO\_READ, and IO\_WRITE. The return value for IO\_SEEK
+is returned in {\bf offset} which in general is a 64 bit value.
+
+When there is an error on Unix systems, you must always set io\_error, and
+on a Win32 system, you must always set win32, and the returned value from
+the OS call GetLastError() in lerror.
+
+For all except IO\_SEEK, {\bf status} is the return result. In general it is
+a positive integer unless there is an error in which case it is -1.
+
+The following describes each call and what you get and what you
+should return:
+
+\begin{description}
+ \item [IO\_OPEN]
+ You will be passed fname, mode, and flags.
+ You must set on return: status, and if there is a Unix error
+ io\_errno must be set to the errno value, and if there is a
+ Win32 error win32 and lerror.
+
+ \item [IO\_READ]
+ You will be passed: count, and buf (buffer of size count).
+ You must set on return: status to the number of bytes
+ read into the buffer (buf) or -1 on an error,
+ and if there is a Unix error
+ io\_errno must be set to the errno value, and if there is a
+ Win32 error, win32 and lerror must be set.
+
+ \item [IO\_WRITE]
+ You will be passed: count, and buf (buffer of size count).
+ You must set on return: status to the number of bytes
+ written from the buffer (buf) or -1 on an error,
+ and if there is a Unix error
+ io\_errno must be set to the errno value, and if there is a
+ Win32 error, win32 and lerror must be set.
+
+ \item [IO\_CLOSE]
+ Nothing will be passed to you. On return you must set
+ status to 0 on success and -1 on failure. If there is a Unix error
+ io\_errno must be set to the errno value, and if there is a
+ Win32 error, win32 and lerror must be set.
+
+ \item [IO\_LSEEK]
+ You will be passed: offset, and whence. offset is a 64 bit value
+ and is the position to seek to relative to whence. whence is one
+ of the following SEEK\_SET, SEEK\_CUR, or SEEK\_END indicating to
+ either to seek to an absolute possition, relative to the current
+ position or relative to the end of the file.
+ You must pass back in offset the absolute location to which you
+ seeked. If there is an error, offset should be set to -1.
+ If there is a Unix error
+ io\_errno must be set to the errno value, and if there is a
+ Win32 error, win32 and lerror must be set.
+
+ Note: Bacula will call IO\_SEEK only when writing a sparse file.
+
+\end{description}
+
+\subsection{bool checkFile(bpContext *ctx, char *fname)}
+If this entry point is set, Bacula will call it after backing up all file
+data during an Accurate backup. It will be passed the full filename for
+each file that Bacula is proposing to mark as deleted. Only files
+previously backed up but not backed up in the current session will be
+marked to be deleted. If you return {\bf false}, the file will be be
+marked deleted. If you return {\bf true} the file will not be marked
+deleted. This permits a plugin to ensure that previously saved virtual
+files or files controlled by your plugin that have not change (not backed
+up in the current job) are not marked to be deleted. This entry point will
+only be called during Accurate Incrmental and Differential backup jobs.
+
+
+\section{Bacula Plugin Entrypoints}
+When Bacula calls one of your plugin entrypoints, you can call back to
+the entrypoints in Bacula that were supplied during the xxx plugin call
+to get or set information within Bacula.
+
+\subsection{bRC registerBaculaEvents(bpContext *ctx, ...)}
+This Bacula entrypoint will allow you to register to receive events
+that are not autmatically passed to your plugin by default. This
+entrypoint currently is unimplemented.
+
+\subsection{bRC getBaculaValue(bpContext *ctx, bVariable var, void *value)}
+Calling this entrypoint, you can obtain specific values that are available
+in Bacula. The following Variables can be referenced:
+\begin{itemize}
+\item bVarJobId returns an int
+\item bVarFDName returns a char *
+\item bVarLevel returns an int
+\item bVarClient returns a char *
+\item bVarJobName returns a char *
+\item bVarJobStatus returns an int
+\item bVarSinceTime returns an int (time\_t)
+\item bVarAccurate returns an int
+\end{itemize}
+
+\subsection{bRC setBaculaValue(bpContext *ctx, bVariable var, void *value)}
+Calling this entrypoint allows you to set particular values in
+Bacula. The only variable that can currently be set is
+{\bf bVarFileSeen} and the value passed is a char * that points
+to the full filename for a file that you are indicating has been
+seen and hence is not deleted.
+
+\subsection{bRC JobMessage(bpContext *ctx, const char *file, int line,
+ int type, utime\_t mtime, const char *fmt, ...)}
+This call permits you to put a message in the Job Report.
+
+
+\subsection{bRC DebugMessage(bpContext *ctx, const char *file, int line,
+ int level, const char *fmt, ...)}
+This call permits you to print a debug message.
+
+
+\subsection{void baculaMalloc(bpContext *ctx, const char *file, int line,
+ size\_t size)}
+This call permits you to obtain memory from Bacula's memory allocator.
+
+
+\subsection{void baculaFree(bpContext *ctx, const char *file, int line, void *mem)}
+This call permits you to free memory obtained from Bacula's memory allocator.
+
+\section{Building Bacula Plugins}
+There is currently one sample program {\bf example-plugin-fd.c} and
+one working plugin {\bf bpipe-fd.c} that can be found in the Bacula
+{\bf src/plugins/fd} directory. Both are built with the following:
+
+\begin{verbatim}
+ cd <bacula-source>
+ ./configure <your-options>
+ make
+ ...
+ cd src/plugins/fd
+ make
+ make test
+\end{verbatim}
+
+After building Bacula and changing into the src/plugins/fd directory,
+the {\bf make} command will build the {\bf bpipe-fd.so} plugin, which
+is a very useful and working program.
+
+The {\bf make test} command will build the {\bf example-plugin-fd.so}
+plugin and a binary named {\bf main}, which is build from the source
+code located in {\bf src/filed/fd\_plugins.c}.
+
+If you execute {\bf ./main}, it will load and run the example-plugin-fd
+plugin simulating a small number of the calling sequences that Bacula uses
+in calling a real plugin. This allows you to do initial testing of
+your plugin prior to trying it with Bacula.
+
+You can get a good idea of how to write your own plugin by first
+studying the example-plugin-fd, and actually running it. Then
+it can also be instructive to read the bpipe-fd.c code as it is
+a real plugin, which is still rather simple and small.
+
+When actually writing your own plugin, you may use the example-plugin-fd.c
+code as a template for your code.

+\label{PoolsChapter}
+\index[general]{Volumes!Using Pools to Manage}
+\index[general]{Disk!Automated Backup}
+\index[general]{Using Pools to Manage Volumes}
+\index[general]{Automated Disk Backup}
+
+If you manage five or ten machines and have a nice tape backup, you don't need
+Pools, and you may wonder what they are good for. In this chapter, you will
+see that Pools can help you optimize disk storage space. The same techniques
+can be applied to a shop that has multiple tape drives, or that wants to mount
+various different Volumes to meet their needs.
+
+The rest of this chapter will give an example involving backup to disk
+Volumes, but most of the information applies equally well to tape Volumes.
+
+\label{TheProblem}
+\section{The Problem}
+\index[general]{Problem}
+
+A site that I administer (a charitable organization) had a tape DDS-3 tape
+drive that was failing. The exact reason for the failure is still unknown.
+Worse yet, their full backup size is about 15GB whereas the capacity of their
+broken DDS-3 was at best 8GB (rated 6/12). A new DDS-4 tape drive and the
+necessary cassettes was more expensive than their budget could handle.
+
+\label{TheSolution}
+\section{The Solution}
+\index[general]{Solution}
+
+They want to maintain six months of backup data, and be able to access the old
+files on a daily basis for a week, a weekly basis for a month, then monthly
+for six months. In addition, offsite capability was not needed (well perhaps
+it really is, but it was never used). Their daily changes amount to about
+300MB on the average, or about 2GB per week.
+
+As a consequence, the total volume of data they need to keep to meet their
+needs is about 100GB (15GB x 6 + 2GB x 5 + 0.3 x 7) = 102.1GB.
+
+The chosen solution was to buy a 120GB hard disk for next to nothing -- far
+less than 1/10th the price of a tape drive and the cassettes to handle the
+same amount of data, and to have Bacula write to disk files.
+
+The rest of this chapter will explain how to setup Bacula so that it would
+automatically manage a set of disk files with the minimum sysadmin
+intervention. The system has been running since 22 January 2004 until today
+(23 June 2007) with no intervention, with the exception of adding
+a second 120GB hard disk after a year because their needs grew
+over that time to more than the 120GB (168GB to be exact). The only other
+intervention I have made is a periodic (about once a year) Bacula upgrade.
+
+\label{OverallDesign}
+\section{Overall Design}
+\index[general]{Overall Design}
+\index[general]{Design!Overall}
+
+Getting Bacula to write to disk rather than tape in the simplest case is
+rather easy, and is documented in the previous chapter. In addition, all the
+directives discussed here are explained in that chapter. We'll leave it to you
+to look at the details there. If you haven't read it and are not familiar with
+Pools, you probably should at least read it once quickly for the ideas before
+continuing here.
+
+One needs to consider about what happens if we have only a single large Bacula
+Volume defined on our hard disk. Everything works fine until the Volume fills,
+then Bacula will ask you to mount a new Volume. This same problem applies to
+the use of tape Volumes if your tape fills. Being a hard disk and the only one
+you have, this will be a bit of a problem. It should be obvious that it is
+better to use a number of smaller Volumes and arrange for Bacula to
+automatically recycle them so that the disk storage space can be reused. The
+other problem with a single Volume, is that until version 2.0.0,
+Bacula did not seek within a disk Volume, so restoring a single file can take
+more time than one would expect.
+
+As mentioned, the solution is to have multiple Volumes, or files on the disk.
+To do so, we need to limit the use and thus the size of a single Volume, by
+time, by number of jobs, or by size. Any of these would work, but we chose to
+limit the use of a single Volume by putting a single job in each Volume with
+the exception of Volumes containing Incremental backup where there will be 6
+jobs (a week's worth of data) per volume. The details of this will be
+discussed shortly. This is a single client backup, so if you have multiple
+clients you will need to multiply those numbers by the number of clients,
+or use a different system for switching volumes, such as limiting the
+volume size.
+
+The next problem to resolve is recycling of Volumes. As you noted from above,
+the requirements are to be able to restore monthly for 6 months, weekly for a
+month, and daily for a week. So to simplify things, why not do a Full save
+once a month, a Differential save once a week, and Incremental saves daily.
+Now since each of these different kinds of saves needs to remain valid for
+differing periods, the simplest way to do this (and possibly the only) is to
+have a separate Pool for each backup type.
+
+The decision was to use three Pools: one for Full saves, one for Differential
+saves, and one for Incremental saves, and each would have a different number
+of volumes and a different Retention period to accomplish the requirements.
+
+\label{FullPool}
+\subsection{Full Pool}
+\index[general]{Pool!Full}
+\index[general]{Full Pool}
+
+Putting a single Full backup on each Volume, will require six Full save
+Volumes, and a retention period of six months. The Pool needed to do that is:
+
+\footnotesize
+\begin{verbatim}
+Pool {
+ Name = Full-Pool
+ Pool Type = Backup
+ Recycle = yes
+ AutoPrune = yes
+ Volume Retention = 6 months
+ Maximum Volume Jobs = 1
+ Label Format = Full-
+ Maximum Volumes = 9
+}
+\end{verbatim}
+\normalsize
+
+Since these are disk Volumes, no space is lost by having separate Volumes for
+each backup (done once a month in this case). The items to note are the
+retention period of six months (i.e. they are recycled after six months), that
+there is one job per volume (Maximum Volume Jobs = 1), the volumes will be
+labeled Full-0001, ... Full-0006 automatically. One could have labeled these
+manually from the start, but why not use the features of Bacula.
+
+Six months after the first volume is used, it will be subject to pruning
+and thus recycling, so with a maximum of 9 volumes, there should always be
+3 volumes available (note, they may all be marked used, but they will be
+marked purged and recycled as needed).
+
+If you have two clients, you would want to set {\bf Maximum Volume Jobs} to
+2 instead of one, or set a limit on the size of the Volumes, and possibly
+increase the maximum number of Volumes.
+
+
+\label{DiffPool}
+\subsection{Differential Pool}
+\index[general]{Pool!Differential}
+\index[general]{Differential Pool}
+
+For the Differential backup Pool, we choose a retention period of a bit longer
+than a month and ensure that there is at least one Volume for each of the
+maximum of five weeks in a month. So the following works:
+
+\footnotesize
+\begin{verbatim}
+Pool {
+ Name = Diff-Pool
+ Pool Type = Backup
+ Recycle = yes
+ AutoPrune = yes
+ Volume Retention = 40 days
+ Maximum Volume Jobs = 1
+ Label Format = Diff-
+ Maximum Volumes = 10
+}
+\end{verbatim}
+\normalsize
+
+As you can see, the Differential Pool can grow to a maximum of 9 volumes,
+and the Volumes are retained 40 days and thereafter they can be recycled. Finally
+there is one job per volume. This, of course, could be tightened up a lot, but
+the expense here is a few GB which is not too serious.
+
+If a new volume is used every week, after 40 days, one will have used 7
+volumes, and there should then always be 3 volumes that can be purged and
+recycled.
+
+See the discussion above concering the Full pool for how to handle multiple
+clients.
+
+\label{IncPool}
+\subsection{Incremental Pool}
+\index[general]{Incremental Pool}
+\index[general]{Pool!Incremental}
+
+Finally, here is the resource for the Incremental Pool:
+
+\footnotesize
+\begin{verbatim}
+Pool {
+ Name = Inc-Pool
+ Pool Type = Backup
+ Recycle = yes
+ AutoPrune = yes
+ Volume Retention = 20 days
+ Maximum Volume Jobs = 6
+ Label Format = Inc-
+ Maximum Volumes = 7
+}
+\end{verbatim}
+\normalsize
+
+We keep the data for 20 days rather than just a week as the needs require. To
+reduce the proliferation of volume names, we keep a week's worth of data (6
+incremental backups) in each Volume. In practice, the retention period should
+be set to just a bit more than a week and keep only two or three volumes
+instead of five. Again, the lost is very little and as the system reaches the
+full steady state, we can adjust these values so that the total disk usage
+doesn't exceed the disk capacity.
+
+If you have two clients, the simplest thing to do is to increase the
+maximum volume jobs from 6 to 12. As mentioned above, it is also possible
+limit the size of the volumes. However, in that case, you will need to
+have a better idea of the volume or add sufficient volumes to the pool so
+that you will be assured that in the next cycle (after 20 days) there is
+at least one volume that is pruned and can be recycled.
+
+

+\chapter{Python Scripting}
+\label{PythonChapter}
+\index[general]{Python Scripting}
+\index[general]{Scripting!Python}
+
+You may be asking what Python is and why a scripting language is
+needed in Bacula. The answer to the first question is that Python
+is an Object Oriented scripting language with features similar
+to those found in Perl, but the syntax of the language is much
+cleaner and simpler. The answer to why have scripting in Bacula is to
+give the user more control over the whole backup process. Probably
+the simplest example is when Bacula needs a new Volume name, with
+a scripting language such as Python, you can generate any name
+you want, based on the current state of Bacula.
+
+\section{Python Configuration}
+\index[general]{Python Configuration}
+\index[general]{Configuration!Python}
+
+Python must be enabled during the configuration process by adding
+a \verb:--:with-python, and possibly specifying an alternate
+directory if your Python is not installed in a standard system
+location. If you are using RPMs you will need the python-devel package
+installed.
+
+When Python is configured, it becomes an integral part of Bacula and
+runs in Bacula's address space, so even though it is an interpreted
+language, it is very efficient.
+
+When the Director starts, it looks to see if you have a {\bf
+Scripts Directory} Directive defined (normal default {\bf
+/etc/bacula/scripts}, if so, it looks in that directory for a file named
+{\bf DirStartUp.py}. If it is found, Bacula will pass this file to Python
+for execution. The {\bf Scripts Directory} is a new directive that you add
+to the Director resource of your bacula-dir.conf file.
+
+Note: Bacula does not install Python scripts by default because these
+scripts are for you to program. This means that with a default
+installation with Python enabled, Bacula will print the following error
+message:
+
+\begin{verbatim}
+09-Jun 15:14 bacula-dir: ERROR in pythonlib.c:131 Could not import
+Python script /etc/bacula/scripts/DirStartUp. Python disabled.
+\end{verbatim}
+
+The source code directory {\bf examples/python} contains sample scripts
+for DirStartUp.py, SDStartUp.py, and FDStartUp.py that you might want
+to use as a starting point. Normally, your scripts directory (at least
+where you store the Python scripts) should be writable by Bacula, because
+Python will attempt to write a compiled version of the scripts (e.g.
+DirStartUp.pyc) back to that directory.
+
+When starting with the sample scripts, you can delete any part that
+you will not need, but you should keep all the Bacula Event and Job Event
+definitions. If you do not want a particular event, simply replace the
+existing code with a {\bf noop = 1}.
+
+\section{Bacula Events}
+\index[general]{Bacula Events}
+\index[general]{Events}
+A Bacula event is a point in the Bacula code where Bacula
+will call a subroutine (actually a method) that you have
+defined in the Python StartUp script. Events correspond
+to some significant event such as a Job Start, a Job End,
+Bacula needs a new Volume Name, ... When your script is
+called, it will have access to all the Bacula variables
+specific to the Job (attributes of the Job Object), and
+it can even call some of the Job methods (subroutines)
+or set new values in the Job attributes, such as the
+Priority. You will see below how the events are used.
+
+\section{Python Objects}
+\index[general]{Python Objects}
+\index[general]{Objects!Python}
+
+There are four Python objects that you will need to work with:
+\begin{description}
+\item [The Bacula Object]
+ The Bacula object is created by the Bacula daemon (the Director
+ in the present case) when the daemon starts. It is available to
+ the Python startup script, {\bf DirStartup.py}, by importing the
+ Bacula definitions with {\bf import bacula}. The methods
+ available with this object are described below.
+
+\item [The Bacula Events Class]
+ You create this class in the startup script, and you pass
+ it to the Bacula Object's {\bf set\_events} method. The
+ purpose of the Bacula Events Class is to define what global
+ or daemon events you want to monitor. When one of those events
+ occurs, your Bacula Events Class will be called at the method
+ corresponding to the event. There are currently three events,
+ JobStart, JobEnd, and Exit, which are described in detail below.
+
+\item [The Job Object]
+ When a Job starts, and assuming you have defined a JobStart method
+ in your Bacula Events Class, Bacula will create a Job Object. This
+ object will be passed to the JobStart event. The Job Object has a
+ has good number of read-only members or attributes providing many
+ details of the Job, and it also has a number of writable attributes
+ that allow you to pass information into the Job. These attributes
+ are described below.
+
+\item [The Job Events Class]
+ You create this class in the JobStart method of your Bacula Events
+ class, and it allows you to define which of the possible Job Object
+ events you want to see. You must pass an instance of your Job Events
+ class to the Job Object set\_events() method.
+ Normally, you will probably only have one
+ Job Events Class, which will be instantiated for each Job. However,
+ if you wish to see different events in different Jobs, you may have
+ as many Job Events classes as you wish.
+\end{description}
+
+
+The first thing the startup script must do is to define what global Bacula
+events (daemon events), it wants to see. This is done by creating a
+Bacula Events class, instantiating it, then passing it to the
+{\bf set\_events} method. There are three possible
+events.
+
+\begin{description}
+\item [JobStart]
+ \index[dir]{JobStart}
+ This Python method, if defined, will be called each time a Job is started.
+ The method is passed the class instantiation object as the first argument,
+ and the Bacula Job object as the second argument. The Bacula Job object
+ has several built-in methods, and you can define which ones you
+ want called. If you do not define this method, you will not be able
+ to interact with Bacula jobs.
+
+\item [JobEnd]
+ This Python method, if defined, will be called each time a Job terminates.
+ The method is passed the class instantiation object as the first argument,
+ and the Bacula Job object as the second argument.
+
+\item [Exit]
+ This Python method, if defined, will be called when the Director terminates.
+ The method is passed the class instantiation object as the first argument.
+\end{description}
+
+Access to the Bacula variables and methods is done with:
+
+ import bacula
+
+The following are the read-only attributes provided by the bacula object.
+\begin{description}
+\item [Name]
+\item [ConfigFile]
+\item [WorkingDir]
+\item [Version] string consisting of "Version Build-date"
+\end{description}
+
+
+A simple definition of the Bacula Events Class might be the following:
+
+\footnotesize
+\begin{verbatim}
+import sys, bacula
+class BaculaEvents:
+ def JobStart(self, job):
+ ...
+\end{verbatim}
+\normalsize
+
+Then to instantiate the class and pass it to Bacula, you
+would do:
+
+\footnotesize
+\begin{verbatim}
+bacula.set_events(BaculaEvents()) # register Bacula Events wanted
+\end{verbatim}
+\normalsize
+
+And at that point, each time a Job is started, your BaculaEvents JobStart
+method will be called.
+
+Now to actually do anything with a Job, you must define which Job events
+you want to see, and this is done by defining a JobEvents class containing
+the methods you want called. Each method name corresponds to one of the
+Job Events that Bacula will generate.
+
+A simple Job Events class might look like the following:
+
+\footnotesize
+\begin{verbatim}
+class JobEvents:
+ def NewVolume(self, job):
+ ...
+\end{verbatim}
+\normalsize
+
+Here, your JobEvents class method NewVolume will be called each time
+the Job needs a new Volume name. To actually register the events defined
+in your class with the Job, you must instantiate the JobEvents class and
+set it in the Job {\bf set\_events} variable. Note, this is a bit different
+from how you registered the Bacula events. The registration process must
+be done in the Bacula JobStart event (your method). So, you would modify
+Bacula Events (not the Job events) as follows:
+
+\footnotesize
+\begin{verbatim}
+import sys, bacula
+class BaculaEvents:
+ def JobStart(self, job):
+ events = JobEvents() # create instance of Job class
+ job.set_events(events) # register Job events desired
+ ...
+\end{verbatim}
+\normalsize
+
+When a job event is triggered, the appropriate event definition is
+called in the JobEvents class. This is the means by which your Python
+script or code gets control. Once it has control, it may read job
+attributes, or set them. See below for a list of read-only attributes,
+and those that are writable.
+
+In addition, the Bacula {\bf job} object in the Director has
+a number of methods (subroutines) that can be called. They
+are:
+\begin{description}
+\item [set\_events] The set\_events method takes a single
+ argument, which is the instantiation of the Job Events class
+ that contains the methods that you want called. The method
+ names that will be called must correspond to the Bacula
+ defined events. You may define additional methods but Bacula
+ will not use them.
+\item [run] The run method takes a single string
+ argument, which is the run command (same as in the Console)
+ that you want to submit to start a new Job. The value
+ returned by the run method is the JobId of the job that
+ started, or -1 if there was an error.
+\item [write] The write method is used to be able to send
+ print output to the Job Report. This will be described later.
+\item[cancel] The cancel method takes a single integer argument,
+ which is a JobId. If JobId is found, it will be canceled.
+\item [DoesVolumeExist] The DoesVolumeExist method takes a single
+ string argument, which is the Volume name, and returns
+ 1 if the volume exists in the Catalog and 0 if the volume
+ does not exist.
+\end{description}
+
+The following attributes are read/write within the Director
+for the {\bf job} object.
+
+\begin{description}
+\item [Priority] Read or set the Job priority.
+ Note, that setting a Job Priority is effective only before
+ the Job actually starts.
+\item [Level] This attribute contains a string representing the Job
+ level, e.g. Full, Differential, Incremental, ... if read.
+ The level can also be set.
+\end{description}
+
+The following read-only attributes are available within the Director
+for the {\bf job} object.
+
+\begin{description}
+\item [Type] This attribute contains a string representing the Job
+ type, e.g. Backup, Restore, Verify, ...
+\item [JobId] This attribute contains an integer representing the
+ JobId.
+\item [Client] This attribute contains a string with the name of the
+ Client for this job.
+\item [NumVols] This attribute contains an integer with the number of
+ Volumes in the Pool being used by the Job.
+\item [Pool] This attribute contains a string with the name of the Pool
+ being used by the Job.
+\item [Storage] This attribute contains a string with the name of the
+ Storage resource being used by the Job.
+\item [Catalog] This attribute contains a string with the name of the
+ Catalog resource being used by the Job.
+\item [MediaType] This attribute contains a string with the name of the
+ Media Type associated with the Storage resource being used by the Job.
+\item [Job] This attribute contains a string containing the name of the
+ Job resource used by this job (not unique).
+\item [JobName] This attribute contains a string representing the full
+ unique Job name.
+\item [JobStatus] This attribute contains a single character string
+ representing the current Job status. The status may change
+ during execution of the job. It may take on the following
+ values:
+ \begin{description}
+ \item [C] Created, not yet running
+ \item [R] Running
+ \item [B] Blocked
+ \item [T] Completed successfully
+ \item [E] Terminated with errors
+ \item [e] Non-fatal error
+ \item [f] Fatal error
+ \item [D] Verify found differences
+ \item [A] Canceled by user
+ \item [F] Waiting for Client
+ \item [S] Waiting for Storage daemon
+ \item [m] Waiting for new media
+ \item [M] Waiting for media mount
+ \item [s] Waiting for storage resource
+ \item [j] Waiting for job resource
+ \item [c] Waiting for client resource
+ \item [d] Waiting on maximum jobs
+ \item [t] Waiting on start time
+ \item [p] Waiting on higher priority jobs
+ \end{description}
+
+\item [Priority] This attribute contains an integer with the priority
+ assigned to the job.
+\item [CatalogRes] tuple consisting of (DBName, Address, User,
+ Password, Socket, Port, Database Vendor) taken from the Catalog resource
+ for the Job with the exception of Database Vendor, which is
+ one of the following: MySQL, PostgreSQL, SQLite, Internal,
+ depending on what database you configured.
+\item [VolumeName]
+ After a Volume has been purged, this attribute will contain the
+ name of that Volume. At other times, this value may have no meaning.
+\end{description}
+
+The following write-only attributes are available within the
+Director:
+
+\begin{description}
+\item [JobReport] Send line to the Job Report.
+\item [VolumeName] Set a new Volume name. Valid only during the
+ NewVolume event.
+\end{description}
+
+\section{Python Console Command}
+\index[general]{Python Console Command}
+\index[general]{Console Command!Python}
+
+There is a new Console command named {\bf python}. It takes
+a single argument {\bf restart}. Example:
+\begin{verbatim}
+ python restart
+\end{verbatim}
+
+This command restarts the Python interpreter in the Director.
+This can be useful when you are modifying the DirStartUp script,
+because normally Python will cache it, and thus the
+script will be read one time.
+
+\section{Debugging Python Scripts}
+\index[general]{Debugging Python Scripts}
+In general, you debug your Python scripts by using print statements.
+You can also develop your script or important parts of it as a
+separate file using the Python interpreter to run it. Once you
+have it working correctly, you can then call the script from
+within the Bacula Python script (DirStartUp.py).
+
+If you are having problems loading DirStartUp.py, you will probably
+not get any error messages because Bacula can only print Python
+error messages after the Python interpreter is started. However, you
+may be able to see the error messages by starting Bacula in
+a shell window with the {\bf -d1} option on the command line. That
+should cause the Python error messages to be printed in the shell
+window.
+
+If you are getting error messages such as the following when
+loading DirStartUp.py:
+
+\begin{verbatim}
+ Traceback (most recent call last):
+ File "/etc/bacula/scripts/DirStartUp.py", line 6, in ?
+ import time, sys, bacula
+ ImportError: /usr/lib/python2.3/lib-dynload/timemodule.so: undefined
+ symbol: PyInt_FromLong
+ bacula-dir: pythonlib.c:134 Python Import error.
+\end{verbatim}
+
+It is because the DirStartUp script is calling a dynamically loaded
+module (timemodule.so in the above case) that then tries to use
+Python functions exported from the Python interpreter (in this case
+PyInt\_FromLong). The way Bacula is currently linked with Python does
+not permit this. The solution to the problem is to put such functions
+(in this case the import of time into a separate Python script, which
+will do your calculations and return the values you want. Then call
+(not import) this script from the Bacula DirStartUp.py script, and
+it all should work as you expect.
+
+
+
+
+
+\section{Python Example}
+\index[general]{Python Example}
+\index[general]{Example!Python}
+
+An example script for the Director startup file is provided in
+{\bf examples/python/DirStartup.py} as follows:
+
+\footnotesize
+\begin{verbatim}
+#
+# Bacula Python interface script for the Director
+#
+
+# You must import both sys and bacula
+import sys, bacula
+
+# This is the list of Bacula daemon events that you
+# can receive.

+\chapter{Automatic Volume Recycling}
+\label{RecyclingChapter}
+\index[general]{Recycling!Automatic Volume }
+\index[general]{Automatic Volume Recycling }
+
+By default, once Bacula starts writing a Volume, it can append to the
+volume, but it will not overwrite the existing data thus destroying it.
+However when Bacula {\bf recycles} a Volume, the Volume becomes available
+for being reused, and Bacula can at some later time overwrite the previous
+contents of that Volume. Thus all previous data will be lost. If the
+Volume is a tape, the tape will be rewritten from the beginning. If the
+Volume is a disk file, the file will be truncated before being rewritten.
+
+You may not want Bacula to automatically recycle (reuse) tapes. This would
+require a large number of tapes though, and in such a case, it is possible
+to manually recycle tapes. For more on manual recycling, see the section
+entitled \ilink{ Manually Recycling Volumes}{manualrecycling} below in this
+chapter.
+
+Most people prefer to have a Pool of tapes that are used for daily backups and
+recycled once a week, another Pool of tapes that are used for Full backups
+once a week and recycled monthly, and finally a Pool of tapes that are used
+once a month and recycled after a year or two. With a scheme like this, the
+number of tapes in your pool or pools remains constant.
+
+By properly defining your Volume Pools with appropriate Retention periods,
+Bacula can manage the recycling (such as defined above) automatically.
+
+Automatic recycling of Volumes is controlled by four records in the {\bf
+Pool} resource definition in the Director's configuration file. These four
+records are:
+
+\begin{itemize}
+\item AutoPrune = yes
+\item VolumeRetention = \lt{}time\gt{}
+\item Recycle = yes
+\item RecyclePool = \lt{}APool\gt{} (\textit{This require bacula 2.1.4 or greater})
+\end{itemize}
+
+The above three directives are all you need assuming that you fill
+each of your Volumes then wait the Volume Retention period before
+reusing them. If you want Bacula to stop using a Volume and recycle
+it before it is full, you will need to use one or more additional
+directives such as:
+\begin{itemize}
+\item Use Volume Once = yes
+\item Volume Use Duration = ttt
+\item Maximum Volume Jobs = nnn
+\item Maximum Volume Bytes = mmm
+\end{itemize}
+Please see below and
+the \ilink{Basic Volume Management}{DiskChapter} chapter
+of this manual for more complete examples.
+
+Automatic recycling of Volumes is performed by Bacula only when it wants a
+new Volume and no appendable Volumes are available in the Pool. It will then
+search the Pool for any Volumes with the {\bf Recycle} flag set and the
+Volume Status is {\bf Purged}. At that point, it will choose the oldest
+purged volume and recycle it.
+
+If there are no volumes with Status {\bf Purged}, then
+the recycling occurs in two steps:
+The first is that the Catalog for a Volume must be pruned of all Jobs (i.e.
+Purged). Files contained on that Volume, and the second step is the actual
+recycling of the Volume. Only Volumes marked {\bf Full} or {\bf Used} will
+be considerd for pruning. The Volume will be purged if the VolumeRetention
+period has expired. When a Volume is marked as Purged, it means that no
+Catalog records reference that Volume, and the Volume can be recycled.
+Until recycling actually occurs, the Volume data remains intact. If no
+Volumes can be found for recycling for any of the reasons stated above,
+Bacula will request operator intervention (i.e. it will ask you to label a
+new volume).
+
+A key point mentioned above, that can be a source of frustration, is that Bacula
+will only recycle purged Volumes if there is no other appendable Volume
+available, otherwise, it will always write to an appendable Volume before
+recycling even if there are Volume marked as Purged. This preserves your data
+as long as possible. So, if you wish to "force" Bacula to use a purged
+Volume, you must first ensure that no other Volume in the Pool is marked {\bf
+Append}. If necessary, you can manually set a volume to {\bf Full}. The reason
+for this is that Bacula wants to preserve the data on your old tapes (even
+though purged from the catalog) as long as absolutely possible before
+overwriting it. There are also a number of directives such as
+{\bf Volume Use Duration} that will automatically mark a volume as {\bf
+Used} and thus no longer appendable.
+
+\label{AutoPruning}
+\section{Automatic Pruning}
+\index[general]{Automatic Pruning}
+\index[general]{Pruning!Automatic}
+
+As Bacula writes files to tape, it keeps a list of files, jobs, and volumes
+in a database called the catalog. Among other things, the database helps
+Bacula to decide which files to back up in an incremental or differential
+backup, and helps you locate files on past backups when you want to restore
+something. However, the catalog will grow larger and larger as time goes
+on, and eventually it can become unacceptably large.
+
+Bacula's process for removing entries from the catalog is called Pruning.
+The default is Automatic Pruning, which means that once an entry reaches a
+certain age (e.g. 30 days old) it is removed from the catalog. Once a job
+has been pruned, you can still restore it from the backup tape, but one
+additional step is required: scanning the volume with bscan. The
+alternative to Automatic Pruning is Manual Pruning, in which you explicitly
+tell Bacula to erase the catalog entries for a volume. You'd usually do
+this when you want to reuse a Bacula volume, because there's no point in
+keeping a list of files that USED TO BE on a tape. Or, if the catalog is
+starting to get too big, you could prune the oldest jobs to save space.
+Manual pruning is done with the \ilink{ prune command}{ManualPruning} in
+the console. (thanks to Bryce Denney for the above explanation).
+
+\section{Pruning Directives}
+\index[general]{Pruning Directives }
+\index[general]{Directives!Pruning }
+
+There are three pruning durations. All apply to catalog database records and
+not to the actual data in a Volume. The pruning (or retention) durations are
+for: Volumes (Media records), Jobs (Job records), and Files (File records).
+The durations inter-depend a bit because if Bacula prunes a Volume, it
+automatically removes all the Job records, and all the File records. Also when
+a Job record is pruned, all the File records for that Job are also pruned
+(deleted) from the catalog.
+
+Having the File records in the database means that you can examine all the
+files backed up for a particular Job. They take the most space in the catalog
+(probably 90-95\% of the total). When the File records are pruned, the Job
+records can remain, and you can still examine what Jobs ran, but not the
+details of the Files backed up. In addition, without the File records, you
+cannot use the Console restore command to restore the files.
+
+When a Job record is pruned, the Volume (Media record) for that Job can still
+remain in the database, and if you do a "list volumes", you will see the
+volume information, but the Job records (and its File records) will no longer
+be available.
+
+In each case, pruning removes information about where older files are, but it
+also prevents the catalog from growing to be too large. You choose the
+retention periods in function of how many files you are backing up and the
+time periods you want to keep those records online, and the size of the
+database. You can always re-insert the records (with 98\% of the original data)
+by using "bscan" to scan in a whole Volume or any part of the volume that
+you want.
+
+By setting {\bf AutoPrune} to {\bf yes} you will permit {\bf Bacula} to
+automatically prune all Volumes in the Pool when a Job needs another Volume.
+Volume pruning means removing records from the catalog. It does not shrink the
+size of the Volume or affect the Volume data until the Volume gets
+overwritten. When a Job requests another volume and there are no Volumes with
+Volume Status {\bf Append} available, Bacula will begin volume pruning. This
+means that all Jobs that are older than the {\bf VolumeRetention} period will
+be pruned from every Volume that has Volume Status {\bf Full} or {\bf Used}
+and has Recycle set to {\bf yes}. Pruning consists of deleting the
+corresponding Job, File, and JobMedia records from the catalog database. No
+change to the physical data on the Volume occurs during the pruning process.
+When all files are pruned from a Volume (i.e. no records in the catalog), the
+Volume will be marked as {\bf Purged} implying that no Jobs remain on the
+volume. The Pool records that control the pruning are described below.
+
+\begin{description}
+
+\item [AutoPrune = \lt{}yes|no\gt{}]
+ \index[console]{AutoPrune }
+ If AutoPrune is set to {\bf yes} (default), Bacula
+ will automatically apply the Volume retention period when running a Job and
+ it needs a new Volume but no appendable volumes are available. At that point,
+ Bacula will prune all Volumes that can be pruned (i.e. AutoPrune set) in an
+ attempt to find a usable volume. If during the autoprune, all files are
+ pruned from the Volume, it will be marked with VolStatus {\bf Purged}. The
+ default is {\bf yes}. Note, that although the File and Job records may be
+ pruned from the catalog, a Volume will be marked Purged (and hence
+ ready for recycling) if the Volume status is Append, Full, Used, or Error.
+ If the Volume has another status, such as Archive, Read-Only, Disabled,
+ Busy, or Cleaning, the Volume status will not be changed to Purged.
+
+\item [Volume Retention = \lt{}time-period-specification\gt{}]
+ \index[console]{Volume Retention}
+ The Volume Retention record defines the length of time that Bacula will
+ guarantee that the Volume is not reused counting from the time the last
+ job stored on the Volume terminated. A key point is that this time
+ period is not even considered as long at the Volume remains appendable.
+ The Volume Retention period count down begins only when the Append
+ status has been changed to some othe status (Full, Used, Purged, ...).
+
+ When this time period expires, and if {\bf AutoPrune} is set to {\bf
+ yes}, and a new Volume is needed, but no appendable Volume is available,
+ Bacula will prune (remove) Job records that are older than the specified
+ Volume Retention period.
+
+ The Volume Retention period takes precedence over any Job Retention
+ period you have specified in the Client resource. It should also be
+ noted, that the Volume Retention period is obtained by reading the
+ Catalog Database Media record rather than the Pool resource record.
+ This means that if you change the VolumeRetention in the Pool resource
+ record, you must ensure that the corresponding change is made in the
+ catalog by using the {\bf update pool} command. Doing so will insure
+ that any new Volumes will be created with the changed Volume Retention
+ period. Any existing Volumes will have their own copy of the Volume
+ Retention period that can only be changed on a Volume by Volume basis
+ using the {\bf update volume} command.
+
+ When all file catalog entries are removed from the volume, its VolStatus is
+ set to {\bf Purged}. The files remain physically on the Volume until the
+ volume is overwritten.
+
+ Retention periods are specified in seconds, minutes, hours, days, weeks,
+ months, quarters, or years on the record. See the
+ \ilink{Configuration chapter}{Time} of this manual for
+ additional details of time specification.
+
+The default is 1 year.
+% TODO: if that is the format, should it be in quotes? decide on a style
+
+\item [Recycle = \lt{}yes|no\gt{}]
+ \index[fd]{Recycle }
+ This statement tells Bacula whether or not the particular Volume can be
+ recycled (i.e. rewritten). If Recycle is set to {\bf no} (the
+ default), then even if Bacula prunes all the Jobs on the volume and it
+ is marked {\bf Purged}, it will not consider the tape for recycling. If
+ Recycle is set to {\bf yes} and all Jobs have been pruned, the volume
+ status will be set to {\bf Purged} and the volume may then be reused
+ when another volume is needed. If the volume is reused, it is relabeled
+ with the same Volume Name, however all previous data will be lost.
+ \end{description}
+
+ It is also possible to "force" pruning of all Volumes in the Pool
+ associated with a Job by adding {\bf Prune Files = yes} to the Job resource.
+
+\label{Recycling}
+\label{RecyclingAlgorithm}
+\section{Recycling Algorithm}
+\index[general]{Algorithm!Recycling }
+\index[general]{Recycling Algorithm }
+
+After all Volumes of a Pool have been pruned (as mentioned above, this happens
+when a Job needs a new Volume and no appendable Volumes are available), Bacula
+will look for the oldest Volume that is Purged (all Jobs and Files expired),
+and if the {\bf Recycle} flag is on (Recycle=yes) for that Volume, Bacula will
+relabel it and write new data on it.
+
+As mentioned above, there are two key points for getting a Volume
+to be recycled. First, the Volume must no longer be marked Append (there
+are a number of directives to automatically make this change), and second
+since the last write on the Volume, one or more of the Retention periods
+must have expired so that there are no more catalog backup job records
+that reference that Volume. Once both those conditions are satisfied,
+the volume can be marked Purged and hence recycled.
+
+The full algorithm that Bacula uses when it needs a new Volume is:
+\index[general]{New Volume Algorithm}
+\index[general]{Algorithm!New Volume}
+
+The algorithm described below assumes that AutoPrune is enabled,
+that Recycling is turned on, and that you have defined
+appropriate Retention periods, or used the defaults for all these
+items.
+
+\begin{itemize}
+\item If the request is for an Autochanger device, look only
+ for Volumes in the Autochanger (i.e. with InChanger set and that have
+ the correct Storage device).
+\item Search the Pool for a Volume with VolStatus=Append (if there is more
+ than one, the Volume with the oldest date last written is chosen. If
+ two have the same date then the one with the lowest MediaId is chosen).
+\item Search the Pool for a Volume with VolStatus=Recycle and the InChanger
+ flag is set true (if there is more than one, the Volume with the oldest
+ date last written is chosen. If two have the same date then the one
+ with the lowest MediaId is chosen).
+\item Try recycling any purged Volumes.
+\item Prune volumes applying Volume retention period (Volumes with VolStatus
+ Full, Used, or Append are pruned). Note, even if all the File and Job
+ records are pruned from a Volume, the Volume will not be marked Purged
+ until the Volume retention period expires.
+\item Search the Pool for a Volume with VolStatus=Purged
+\item If a Pool named "Scratch" exists, search for a Volume and if found
+ move it to the current Pool for the Job and use it. Note, when
+ the Scratch Volume is moved into the current Pool, the basic
+ Pool defaults are applied as if it is a newly labeled Volume
+ (equivalent to an {\bf update volume from pool} command).
+\item If we were looking for Volumes in the Autochanger, go back to
+ step 2 above, but this time, look for any Volume whether or not
+ it is in the Autochanger.
+\item Attempt to create a new Volume if automatic labeling enabled
+ If Python is enabled, a Python NewVolume event is generated before
+ the Label Format directve is used. If the maximum number of Volumes
+ specified for the pool is reached, a new Volume will not be created.
+\item Prune the oldest Volume if RecycleOldestVolume=yes (the Volume with the
+ oldest LastWritten date and VolStatus equal to Full, Recycle, Purged, Used,
+ or Append is chosen). This record ensures that all retention periods are
+ properly respected.
+\item Purge the oldest Volume if PurgeOldestVolume=yes (the Volume with the
+ oldest LastWritten date and VolStatus equal to Full, Recycle, Purged, Used,
+ or Append is chosen). We strongly recommend against the use of {\bf
+ PurgeOldestVolume} as it can quite easily lead to loss of current backup
+ data.
+\item Give up and ask operator.
+\end{itemize}
+
+The above occurs when Bacula has finished writing a Volume or when no Volume
+is present in the drive.
+
+On the other hand, if you have inserted a different Volume after the last job,
+and Bacula recognizes the Volume as valid, it will request authorization from
+the Director to use this Volume. In this case, if you have set {\bf Recycle
+Current Volume = yes} and the Volume is marked as Used or Full, Bacula will
+prune the volume and if all jobs were removed during the pruning (respecting
+the retention periods), the Volume will be recycled and used.
+
+The recycling algorithm in this case is:
+\begin{itemize}
+\item If the VolStatus is {\bf Append} or {\bf Recycle}
+ is set, the volume will be used.
+\item If {\bf Recycle Current Volume} is set and the volume is marked {\bf
+ Full} or {\bf Used}, Bacula will prune the volume (applying the retention
+ period). If all Jobs are pruned from the volume, it will be recycled.
+\end{itemize}
+
+This permits users to manually change the Volume every day and load tapes in
+an order different from what is in the catalog, and if the volume does not
+contain a current copy of your backup data, it will be used.
+
+A few points from Alan Brown to keep in mind:
+
+\begin{enumerate}
+\item If a pool doesn't have maximum volumes defined then Bacula will prefer to
+ demand new volumes over forcibly purging older volumes.
+
+\item If volumes become free through pruning and the Volume retention period has
+ expired, then they get marked as "purged" and are immediately available for
+ recycling - these will be used in preference to creating new volumes.
+
+\item If the Job, File, and Volume retention periods are different, then
+ it's common to see a tape with no files or jobs listed in the database,
+ but which is still not marked as "purged".
+\end{enumerate}
+
+
+\section{Recycle Status}
+\index[general]{Status!Recycle }
+\index[general]{Recycle Status }
+
+Each Volume inherits the Recycle status (yes or no) from the Pool resource
+record when the Media record is created (normally when the Volume is labeled).
+This Recycle status is stored in the Media record of the Catalog. Using
+the Console program, you may subsequently change the Recycle status for each
+Volume. For example in the following output from {\bf list volumes}:
+
+\footnotesize
+\begin{verbatim}
++----------+-------+--------+---------+------------+--------+-----+
+| VolumeNa | Media | VolSta | VolByte | LastWritte | VolRet | Rec |
++----------+-------+--------+---------+------------+--------+-----+
+| File0001 | File | Full | 4190055 | 2002-05-25 | 14400 | 1 |
+| File0002 | File | Full | 1896460 | 2002-05-26 | 14400 | 1 |
+| File0003 | File | Full | 1896460 | 2002-05-26 | 14400 | 1 |
+| File0004 | File | Full | 1896460 | 2002-05-26 | 14400 | 1 |
+| File0005 | File | Full | 1896460 | 2002-05-26 | 14400 | 1 |
+| File0006 | File | Full | 1896460 | 2002-05-26 | 14400 | 1 |
+| File0007 | File | Purged | 1896466 | 2002-05-26 | 14400 | 1 |
++----------+-------+--------+---------+------------+--------+-----+
+\end{verbatim}
+\normalsize
+
+all the volumes are marked as recyclable, and the last Volume, {\bf File0007}
+has been purged, so it may be immediately recycled. The other volumes are all
+marked recyclable and when their Volume Retention period (14400 seconds or four
+hours) expires, they will be eligible for pruning, and possibly recycling.
+Even though Volume {\bf File0007} has been purged, all the data on the Volume
+is still recoverable. A purged Volume simply means that there are no entries
+in the Catalog. Even if the Volume Status is changed to {\bf Recycle}, the
+data on the Volume will be recoverable. The data is lost only when the Volume
+is re-labeled and re-written.
+
+To modify Volume {\bf File0001} so that it cannot be recycled, you use the
+{\bf update volume pool=File} command in the console program, or simply {\bf
+update} and Bacula will prompt you for the information.
+
+\footnotesize
+\begin{verbatim}
++----------+------+-------+---------+-------------+-------+-----+
+| VolumeNa | Media| VolSta| VolByte | LastWritten | VolRet| Rec |
++----------+------+-------+---------+-------------+-------+-----+
+| File0001 | File | Full | 4190055 | 2002-05-25 | 14400 | 0 |
+| File0002 | File | Full | 1897236 | 2002-05-26 | 14400 | 1 |
+| File0003 | File | Full | 1896460 | 2002-05-26 | 14400 | 1 |
+| File0004 | File | Full | 1896460 | 2002-05-26 | 14400 | 1 |
+| File0005 | File | Full | 1896460 | 2002-05-26 | 14400 | 1 |
+| File0006 | File | Full | 1896460 | 2002-05-26 | 14400 | 1 |
+| File0007 | File | Purged| 1896466 | 2002-05-26 | 14400 | 1 |
++----------+------+-------+---------+-------------+-------+-----+
+\end{verbatim}
+\normalsize
+
+In this case, {\bf File0001} will never be automatically recycled. The same
+effect can be achieved by setting the Volume Status to Read-Only.
+
+As you have noted, the Volume Status (VolStatus) column in the
+catalog database contains the current status of the Volume, which
+is normally maintained automatically by Bacula. To give you an
+idea of some of the values it can take during the life cycle of
+a Volume, here is a picture created by Arno Lehmann:
+
+\footnotesize
+\begin{verbatim}
+A typical volume life cycle is like this:
+
+ because job count or size limit exceeded
+ Append ----------------------------------------> Used
+ ^ |
+ | First Job writes to Retention time passed |
+ | the volume and recycling takes |
+ | place |
+ | v
+ Recycled <-------------------------------------- Purged
+ Volume is selected for reuse

+\section{Making Bacula Use a Single Tape}
+\label{singletape}
+\index[general]{Tape!Making Bacula Use a Single}
+\index[general]{Making Bacula Use a Single Tape}
+
+Most people will want Bacula to fill a tape and when it is full, a new tape
+will be mounted, and so on. However, as an extreme example, it is possible for
+Bacula to write on a single tape, and every night to rewrite it. To get this
+to work, you must do two things: first, set the VolumeRetention to less than
+your save period (one day), and the second item is to make Bacula mark the
+tape as full after using it once. This is done using {\bf UseVolumeOnce =
+yes}. If this latter record is not used and the tape is not full after the
+first time it is written, Bacula will simply append to the tape and eventually
+request another volume. Using the tape only once, forces the tape to be marked
+{\bf Full} after each use, and the next time {\bf Bacula} runs, it will
+recycle the tape.
+
+An example Pool resource that does this is:
+
+\footnotesize
+\begin{verbatim}
+Pool {
+ Name = DDS-4
+ Use Volume Once = yes
+ Pool Type = Backup
+ AutoPrune = yes
+ VolumeRetention = 12h # expire after 12 hours
+ Recycle = yes
+}
+\end{verbatim}
+\normalsize
+
+\section{Daily, Weekly, Monthly Tape Usage Example}
+\label{usageexample}
+\index[general]{Daily, Weekly, Monthly Tape Usage Example }
+\index[general]{Example!Daily Weekly Monthly Tape Usage }
+
+This example is meant to show you how one could define a fixed set of volumes
+that Bacula will rotate through on a regular schedule. There are an infinite
+number of such schemes, all of which have various advantages and
+disadvantages.
+
+We start with the following assumptions:
+
+\begin{itemize}
+\item A single tape has more than enough capacity to do a full save.
+\item There are ten tapes that are used on a daily basis for incremental
+ backups. They are prelabeled Daily1 ... Daily10.
+\item There are four tapes that are used on a weekly basis for full backups.
+ They are labeled Week1 ... Week4.
+\item There are 12 tapes that are used on a monthly basis for full backups.
+ They are numbered Month1 ... Month12
+\item A full backup is done every Saturday evening (tape inserted Friday
+ evening before leaving work).
+\item No backups are done over the weekend (this is easy to change).
+\item The first Friday of each month, a Monthly tape is used for the Full
+ backup.
+\item Incremental backups are done Monday - Friday (actually Tue-Fri
+ mornings).
+% TODO: why this "actually"? does this need to be explained?
+ \end{itemize}
+
+We start the system by doing a Full save to one of the weekly volumes or one
+of the monthly volumes. The next morning, we remove the tape and insert a
+Daily tape. Friday evening, we remove the Daily tape and insert the next tape
+in the Weekly series. Monday, we remove the Weekly tape and re-insert the
+Daily tape. On the first Friday of the next month, we insert the next Monthly
+tape in the series rather than a Weekly tape, then continue. When a Daily tape
+finally fills up, {\bf Bacula} will request the next one in the series, and
+the next day when you notice the email message, you will mount it and {\bf
+Bacula} will finish the unfinished incremental backup.
+
+What does this give? Well, at any point, you will have the last complete
+Full save plus several Incremental saves. For any given file you want to
+recover (or your whole system), you will have a copy of that file every day
+for at least the last 14 days. For older versions, you will have at least three
+and probably four Friday full saves of that file, and going back further, you
+will have a copy of that file made on the beginning of the month for at least
+a year.
+
+So you have copies of any file (or your whole system) for at least a year, but

+\index[general]{Example!Automatic Pruning and Recycling }
+
+Perhaps the best way to understand the various resource records that come into
+play during automatic pruning and recycling is to run a Job that goes through
+the whole cycle. If you add the following resources to your Director's
+configuration file:
+
+\footnotesize
+\begin{verbatim}
+Schedule {
+ Name = "30 minute cycle"
+ Run = Level=Full Pool=File Messages=Standard Storage=File
+ hourly at 0:05
+ Run = Level=Full Pool=File Messages=Standard Storage=File
+ hourly at 0:35
+}
+Job {
+ Name = "Filetest"
+ Type = Backup
+ Level = Full
+ Client=XXXXXXXXXX
+ FileSet="Test Files"
+ Messages = Standard
+ Storage = File
+ Pool = File
+ Schedule = "30 minute cycle"
+}
+# Definition of file storage device
+Storage {
+ Name = File
+ Address = XXXXXXXXXXX
+ SDPort = 9103
+ Password = XXXXXXXXXXXXX
+ Device = FileStorage
+ Media Type = File
+}
+FileSet {
+ Name = "Test Files"
+ Include = signature=MD5 {
+ fffffffffffffffff
+ }
+ Exclude = { *.o }
+}
+Pool {
+ Name = File
+ Use Volume Once = yes
+ Pool Type = Backup
+ LabelFormat = "File"
+ AutoPrune = yes
+ VolumeRetention = 4h
+ Maximum Volumes = 12
+ Recycle = yes
+}
+\end{verbatim}
+\normalsize
+
+Where you will need to replace the {\bf ffffffffff}'s by the appropriate files
+to be saved for your configuration. For the FileSet Include, choose a
+directory that has one or two megabytes maximum since there will probably be
+approximately eight copies of the directory that {\bf Bacula} will cycle through.
+
+In addition, you will need to add the following to your Storage daemon's
+configuration file:
+
+\footnotesize
+\begin{verbatim}
+Device {
+ Name = FileStorage
+ Media Type = File
+ Archive Device = /tmp
+ LabelMedia = yes;
+ Random Access = Yes;
+ AutomaticMount = yes;
+ RemovableMedia = no;
+ AlwaysOpen = no;
+}
+\end{verbatim}
+\normalsize
+
+With the above resources, Bacula will start a Job every half hour that saves a
+copy of the directory you chose to /tmp/File0001 ... /tmp/File0012. After 4
+hours, Bacula will start recycling the backup Volumes (/tmp/File0001 ...). You
+should see this happening in the output produced. Bacula will automatically
+create the Volumes (Files) the first time it uses them.
+
+To turn it off, either delete all the resources you've added, or simply
+comment out the {\bf Schedule} record in the {\bf Job} resource.
+
+\section{Manually Recycling Volumes}
+\label{manualrecycling}
+\index[general]{Volumes!Manually Recycling }
+\index[general]{Manually Recycling Volumes }
+
+Although automatic recycling of Volumes is implemented in version 1.20 and
+later (see the
+\ilink{Automatic Recycling of Volumes}{RecyclingChapter} chapter of
+this manual), you may want to manually force reuse (recycling) of a Volume.
+
+Assuming that you want to keep the Volume name, but you simply want to write
+new data on the tape, the steps to take are:
+
+\begin{itemize}
+\item Use the {\bf update volume} command in the Console to ensure that the
+ {\bf Recycle} field is set to {\bf 1}
+\item Use the {\bf purge jobs volume} command in the Console to mark the
+ Volume as {\bf Purged}. Check by using {\bf list volumes}.
+\end{itemize}
+
+Once the Volume is marked Purged, it will be recycled the next time a Volume
+is needed.
+
+If you wish to reuse the tape by giving it a new name, follow the following
+steps:
+
+\begin{itemize}
+\item Use the {\bf purge jobs volume} command in the Console to mark the
+ Volume as {\bf Purged}. Check by using {\bf list volumes}.
+\item In Bacula version 1.30 or greater, use the Console {\bf relabel}
+ command to relabel the Volume.
+\end{itemize}
+
+Please note that the relabel command applies only to tape Volumes.
+
+For Bacula versions prior to 1.30 or to manually relabel the Volume, use the
+instructions below:
+
+\begin{itemize}
+\item Use the {\bf delete volume} command in the Console to delete the Volume
+ from the Catalog.
+\item If a different tape is mounted, use the {\bf unmount} command,
+ remove the tape, and insert the tape to be renamed.
+\item Write an EOF mark in the tape using the following commands:
+
+\footnotesize
+\begin{verbatim}
+ mt -f /dev/nst0 rewind
+ mt -f /dev/nst0 weof
+\end{verbatim}
+\normalsize
+
+where you replace {\bf /dev/nst0} with the appropriate device name on your
+system.
+\item Use the {\bf label} command to write a new label to the tape and to
+ enter it in the catalog.
+\end{itemize}
+
+Please be aware that the {\bf delete} command can be dangerous. Once it is
+done, to recover the File records, you must either restore your database as it
+was before the {\bf delete} command, or use the {\bf bscan} utility program to
+scan the tape and recreate the database entries.

+\chapter{System Requirements}
+\label{SysReqs}
+\index[general]{System Requirements }
+\index[general]{Requirements!System }
+
+\begin{itemize}
+\item {\bf Bacula} has been compiled and run on OpenSuSE Linux, FreeBSD, and
+ Solaris systems.
+\item It requires GNU C++ version 2.95 or higher to compile. You can try with
+ other compilers and older versions, but you are on your own. We have
+ successfully compiled and used Bacula using GNU C++ version 4.1.3.
+ Note, in general GNU C++ is a separate package (e.g. RPM) from GNU C, so you
+ need them both loaded. On Red Hat systems, the C++ compiler is part of the
+ {\bf gcc-c++} rpm package.
+\item There are certain third party packages that Bacula may need. Except for
+ MySQL and PostgreSQL, they can all be found in the {\bf depkgs} and {\bf
+ depkgs1} releases. However, most current Linux and FreeBSD systems
+ provide these as system packages.
+\item The minimum versions for each of the databases supported by Bacula
+ are:
+
+ \begin{itemize}
+ \item MySQL 4.1
+ \item PostgreSQL 7.4
+ \item SQLite 2.8.16 or SQLite 3
+ \end{itemize}
+
+\item If you want to build the Win32 binaries, please see the
+ README.mingw32 file in the src/win32 directory. We cross-compile the
+ Win32 release on Linux. We provide documentation on building the Win32
+ version, but due to the complexity, you are pretty much on your own
+ if you want to build it yourself.
+\item {\bf Bacula} requires a good implementation of pthreads to work. This
+ is not the case on some of the BSD systems.
+\item The source code has been written with portability in mind and is mostly
+ POSIX compatible. Thus porting to any POSIX compatible operating system
+ should be relatively easy.
+\item The GNOME Console program is developed and tested under GNOME 2.x.
+ GNOME 1.4 is no longer supported.
+\item The wxWidgets Console program is developed and tested with the latest
+ stable ANSI or Unicode version of
+ \elink{wxWidgets}{\url{http://www.wxwidgets.org/}} (2.6.1). It works fine with the
+ Windows and GTK+-2.x version of wxWidgets, and should also work on other
+ platforms supported by wxWidgets.
+\item The Tray Monitor program is developed for GTK+-2.x. It needs GNOME less
+ or equal to 2.2, KDE greater or equal to 3.1 or any window manager supporting
+ the
+ \elink{ FreeDesktop system tray
+ standard}{\url{http://www.freedesktop.org/Standards/systemtray-spec}}.
+\item If you want to enable command line editing and history, you will need
+ to have /usr/include/termcap.h and either the termcap or the ncurses library
+ loaded (libtermcap-devel or ncurses-devel).
+\item If you want to use DVD as backup medium, you will need to download the
+ \elink{dvd+rw-tools 5.21.4.10.8}{\url{http://fy.chalmers.se/~appro/linux/DVD+RW/}},
+ apply the patch that is in the {\bf patches} directory of the main
+ source tree
+ to make these tools compatible with Bacula, then compile and install them.
+ There is also a patch for dvd+rw-tools version 6.1, and we hope that the
+ patch is integrated into a later version.
+ Do not use the dvd+rw-tools provided by your distribution, unless you
+ are sure it contains the patch. dvd+rw-tools without the patch will not
+ work with Bacula. DVD media is not recommended for serious or important
+ backups because of its low reliability.

+\chapter{The Restore Command}
+\label{RestoreChapter}
+\index[general]{Command!Console Restore}
+\index[general]{Console Restore Command}
+
+\section{General}
+\index[general]{General }
+
+Below, we will discuss restoring files with the Console {\bf restore} command,
+which is the recommended way of doing restoring files. It is not possible
+to restore files by automatically starting a job as you do with Backup,
+Verify, ... jobs. However, in addition to the console restore command,
+there is a standalone program named {\bf bextract}, which also permits
+restoring files. For more information on this program, please see the
+\ilink{Bacula Utility Programs}{bextract} chapter of this manual. We
+don't particularly recommend the {\bf bextract} program because it
+lacks many of the features of the normal Bacula restore, such as the
+ability to restore Win32 files to Unix systems, and the ability to
+restore access control lists (ACL). As a consequence, we recommend,
+wherever possible to use Bacula itself for restores as described below.
+
+You may also want to look at the {\bf bls} program in the same chapter,
+which allows you to list the contents of your Volumes. Finally, if you
+have an old Volume that is no longer in the catalog, you can restore the
+catalog entries using the program named {\bf bscan}, documented in the same
+\ilink{Bacula Utility Programs}{bscan} chapter.
+
+In general, to restore a file or a set of files, you must run a {\bf restore}
+job. That is a job with {\bf Type = Restore}. As a consequence, you will need
+a predefined {\bf restore} job in your {\bf bacula-dir.conf} (Director's
+config) file. The exact parameters (Client, FileSet, ...) that you define are
+not important as you can either modify them manually before running the job or
+if you use the {\bf restore} command, explained below, Bacula will
+automatically set them for you. In fact, you can no longer simply run a restore
+job. You must use the restore command.
+
+Since Bacula is a network backup program, you must be aware that when you
+restore files, it is up to you to ensure that you or Bacula have selected the
+correct Client and the correct hard disk location for restoring those files.
+{\bf Bacula} will quite willingly backup client A, and restore it by sending
+the files to a different directory on client B. Normally, you will want to
+avoid this, but assuming the operating systems are not too different in their
+file structures, this should work perfectly well, if so desired.
+By default, Bacula will restore data to the same Client that was backed
+up, and those data will be restored not to the original places but to
+{\bf /tmp/bacula-restores}. You may modify any of these defaults when the
+restore command prompts you to run the job by selecting the {\bf mod}
+option.
+
+\label{Example1}
+\section{The Restore Command}
+\index[general]{Command!Restore}
+\index[general]{Restore Command}
+
+Since Bacula maintains a catalog of your files and on which Volumes (disk or
+tape), they are stored, it can do most of the bookkeeping work, allowing you
+simply to specify what kind of restore you want (current, before a particular
+date), and what files to restore. Bacula will then do the rest.
+
+This is accomplished using the {\bf restore} command in the Console. First you
+select the kind of restore you want, then the JobIds are selected,
+the File records for those Jobs are placed in an internal Bacula directory
+tree, and the restore enters a file selection mode that allows you to
+interactively walk up and down the file tree selecting individual files to be
+restored. This mode is somewhat similar to the standard Unix {\bf restore}
+program's interactive file selection mode.
+
+If a Job's file records have been pruned from the catalog, the {\bf restore}
+command will be unable to find any files to restore. Bacula will ask if you
+want to restore all of them or if you want to use a regular expression to
+restore only a selection while reading media. See \ilink{FileRegex
+ option}{FileRegex} and below for more details on this.
+
+Within the Console program, after entering the {\bf restore} command, you are
+presented with the following selection prompt:
+
+\footnotesize
+\begin{verbatim}
+First you select one or more JobIds that contain files
+to be restored. You will be presented several methods
+of specifying the JobIds. Then you will be allowed to
+select which files from those JobIds are to be restored.
+To select the JobIds, you have the following choices:
+ 1: List last 20 Jobs run
+ 2: List Jobs where a given File is saved
+ 3: Enter list of comma separated JobIds to select
+ 4: Enter SQL list command
+ 5: Select the most recent backup for a client
+ 6: Select backup for a client before a specified time
+ 7: Enter a list of files to restore
+ 8: Enter a list of files to restore before a specified time
+ 9: Find the JobIds of the most recent backup for a client
+ 10: Find the JobIds for a backup for a client before a specified time
+ 11: Enter a list of directories to restore for found JobIds
+ 12: Cancel
+Select item: (1-12):
+\end{verbatim}
+\normalsize
+
+There are a lot of options, and as a point of reference, most people will
+want to slect item 5 (the most recent backup for a client). The details
+of the above options are:
+
+\begin{itemize}
+\item Item 1 will list the last 20 jobs run. If you find the Job you want,
+ you can then select item 3 and enter its JobId(s).
+
+\item Item 2 will list all the Jobs where a specified file is saved. If you
+ find the Job you want, you can then select item 3 and enter the JobId.
+
+\item Item 3 allows you the enter a list of comma separated JobIds whose
+ files will be put into the directory tree. You may then select which
+ files from those JobIds to restore. Normally, you would use this option
+ if you have a particular version of a file that you want to restore and
+ you know its JobId. The most common options (5 and 6) will not select
+ a job that did not terminate normally, so if you know a file is
+ backed up by a Job that failed (possibly because of a system crash), you
+ can access it through this option by specifying the JobId.
+
+\item Item 4 allows you to enter any arbitrary SQL command. This is
+ probably the most primitive way of finding the desired JobIds, but at
+ the same time, the most flexible. Once you have found the JobId(s), you
+ can select item 3 and enter them.
+
+\item Item 5 will automatically select the most recent Full backup and all
+ subsequent incremental and differential backups for a specified Client.
+ These are the Jobs and Files which, if reloaded, will restore your
+ system to the most current saved state. It automatically enters the
+ JobIds found into the directory tree in an optimal way such that only
+ the most recent copy of any particular file found in the set of Jobs
+ will be restored. This is probably the most convenient of all the above
+ options to use if you wish to restore a selected Client to its most
+ recent state.
+
+ There are two important things to note. First, this automatic selection
+ will never select a job that failed (terminated with an error status).
+ If you have such a job and want to recover one or more files from it,
+ you will need to explicitly enter the JobId in item 3, then choose the
+ files to restore.
+
+ If some of the Jobs that are needed to do the restore have had their
+ File records pruned, the restore will be incomplete. Bacula currently
+ does not correctly detect this condition. You can however, check for
+ this by looking carefully at the list of Jobs that Bacula selects and
+ prints. If you find Jobs with the JobFiles column set to zero, when
+ files should have been backed up, then you should expect problems.
+
+ If all the File records have been pruned, Bacula will realize that there
+ are no file records in any of the JobIds chosen and will inform you. It
+ will then propose doing a full restore (non-selective) of those JobIds.
+ This is possible because Bacula still knows where the beginning of the
+ Job data is on the Volumes, even if it does not know where particular
+ files are located or what their names are.
+
+\item Item 6 allows you to specify a date and time, after which Bacula will
+ automatically select the most recent Full backup and all subsequent
+ incremental and differential backups that started before the specified date
+ and time.
+
+\item Item 7 allows you to specify one or more filenames (complete path
+ required) to be restored. Each filename is entered one at a time or if you
+ prefix a filename with the less-than symbol (\lt{}) Bacula will read that
+ file and assume it is a list of filenames to be restored. If you
+ prefix the filename with a question mark (?), then the filename will
+ be interpreted as an SQL table name, and Bacula will include the rows
+ of that table in the list to be restored. The table must contain the
+ JobId in the first column and the FileIndex in the second column.
+ This table feature is intended for external programs that want to build
+ their own list of files to be restored.
+ The filename entry mode is terminated by entering a blank line.
+
+\item Item 8 allows you to specify a date and time before entering the
+ filenames. See Item 7 above for more details.
+
+\item Item 9 allows you find the JobIds of the most recent backup for
+ a client. This is much like option 5 (it uses the same code), but
+ those JobIds are retained internally as if you had entered them
+ manually. You may then select item 11 (see below) to restore one
+ or more directories.
+
+\item Item 10 is the same as item 9, except that it allows you to enter
+ a before date (as with item 6). These JobIds will then be retained
+ internally.
+
+\index[general]{Restore Directories}
+\item Item 11 allows you to enter a list of JobIds from which you can
+ select directories to be restored. The list of JobIds can have been
+ previously created by using either item 9 or 10 on the menu. You
+ may then enter a full path to a directory name or a filename preceded
+ by a less than sign (\lt{}). The filename should contain a list
+ of directories to be restored. All files in those directories will
+ be restored, but if the directory contains subdirectories, nothing
+ will be restored in the subdirectory unless you explicitly enter its
+ name.
+
+\item Item 12 allows you to cancel the restore command.
+\end{itemize}
+
+As an example, suppose that we select item 5 (restore to most recent state).
+If you have not specified a client=xxx on the command line, it
+it will then ask for the desired Client, which on my system, will print all
+the Clients found in the database as follows:
+
+\footnotesize
+\begin{verbatim}
+Defined clients:
+ 1: Rufus
+ 2: Matou
+ 3: Polymatou
+ 4: Minimatou
+ 5: Minou
+ 6: MatouVerify
+ 7: PmatouVerify
+ 8: RufusVerify
+ 9: Watchdog
+Select Client (File daemon) resource (1-9):
+\end{verbatim}
+\normalsize
+
+You will probably have far fewer Clients than this example, and if you have
+only one Client, it will be automatically selected. In this case, I enter
+{\bf Rufus} to select the Client. Then Bacula needs to know what FileSet is
+to be restored, so it prompts with:
+
+\footnotesize
+\begin{verbatim}
+The defined FileSet resources are:
+ 1: Full Set
+ 2: Other Files
+Select FileSet resource (1-2):
+\end{verbatim}
+\normalsize
+
+If you have only one FileSet defined for the Client, it will be selected
+automatically. I choose item 1, which is my full backup. Normally, you
+will only have a single FileSet for each Job, and if your machines are
+similar (all Linux) you may only have one FileSet for all your Clients.
+
+At this point, {\bf Bacula} has all the information it needs to find the most
+recent set of backups. It will then query the database, which may take a bit
+of time, and it will come up with something like the following. Note, some of
+the columns are truncated here for presentation:
+
+\footnotesize
+\begin{verbatim}
++-------+------+----------+-------------+-------------+------+-------+------------+
+| JobId | Levl | JobFiles | StartTime | VolumeName | File | SesId |VolSesTime |
++-------+------+----------+-------------+-------------+------+-------+------------+
+| 1,792 | F | 128,374 | 08-03 01:58 | DLT-19Jul02 | 67 | 18 | 1028042998 |
+| 1,792 | F | 128,374 | 08-03 01:58 | DLT-04Aug02 | 0 | 18 | 1028042998 |
+| 1,797 | I | 254 | 08-04 13:53 | DLT-04Aug02 | 5 | 23 | 1028042998 |
+| 1,798 | I | 15 | 08-05 01:05 | DLT-04Aug02 | 6 | 24 | 1028042998 |
++-------+------+----------+-------------+-------------+------+-------+------------+
+You have selected the following JobId: 1792,1792,1797
+Building directory tree for JobId 1792 ...
+Building directory tree for JobId 1797 ...
+Building directory tree for JobId 1798 ...
+cwd is: /
+$
+\end{verbatim}
+\normalsize
+
+Depending on the number of {\bf JobFiles} for each JobId, the {\bf Building
+directory tree ..."} can take a bit of time. If you notice ath all the
+JobFiles are zero, your Files have probably been pruned and you will not be
+able to select any individual files -- it will be restore everything or
+nothing.
+
+In our example, Bacula found four Jobs that comprise the most recent backup of
+the specified Client and FileSet. Two of the Jobs have the same JobId because
+that Job wrote on two different Volumes. The third Job was an incremental
+backup to the previous Full backup, and it only saved 254 Files compared to
+128,374 for the Full backup. The fourth Job was also an incremental backup
+that saved 15 files.
+
+Next Bacula entered those Jobs into the directory tree, with no files marked
+to be restored as a default, tells you how many files are in the tree, and
+tells you that the current working directory ({\bf cwd}) is /. Finally, Bacula
+prompts with the dollar sign (\$) to indicate that you may enter commands to
+move around the directory tree and to select files.
+
+If you want all the files to automatically be marked when the directory
+tree is built, you could have entered the command {\bf restore all}, or
+at the \$ prompt, you can simply enter {\bf mark *}.
+
+Instead of choosing item 5 on the first menu (Select the most recent backup
+for a client), if we had chosen item 3 (Enter list of JobIds to select) and we
+had entered the JobIds {\bf 1792,1797,1798} we would have arrived at the same
+point.
+
+One point to note, if you are manually entering JobIds, is that you must enter
+them in the order they were run (generally in increasing JobId order). If you
+enter them out of order and the same file was saved in two or more of the
+Jobs, you may end up with an old version of that file (i.e. not the most
+recent).
+
+Directly entering the JobIds can also permit you to recover data from
+a Job that wrote files to tape but that terminated with an error status.
+
+While in file selection mode, you can enter {\bf help} or a question mark (?)
+to produce a summary of the available commands:
+
+\footnotesize
+\begin{verbatim}
+ Command Description
+ ======= ===========
+ cd change current directory
+ count count marked files in and below the cd
+ dir long list current directory, wildcards allowed
+ done leave file selection mode
+ estimate estimate restore size
+ exit same as done command
+ find find files, wildcards allowed
+ help print help
+ ls list current directory, wildcards allowed
+ lsmark list the marked files in and below the cd
+ mark mark dir/file to be restored recursively in dirs
+ markdir mark directory name to be restored (no files)
+ pwd print current working directory
+ unmark unmark dir/file to be restored recursively in dir
+ unmarkdir unmark directory name only no recursion
+ quit quit and do not do restore
+ ? print help
+\end{verbatim}
+\normalsize
+
+As a default no files have been selected for restore (unless you
+added {\bf all} to the command line. If you want to restore
+everything, at this point, you should enter {\bf mark *}, and then {\bf done}
+and {\bf Bacula} will write the bootstrap records to a file and request your
+approval to start a restore job.
+
+If you do not enter the above mentioned {\bf mark *} command, you will start
+with an empty slate. Now you can simply start looking at the tree and {\bf
+mark} particular files or directories you want restored. It is easy to make
+a mistake in specifying a file to mark or unmark, and Bacula's error handling
+is not perfect, so please check your work by using the {\bf ls} or {\bf dir}
+commands to see what files are actually selected. Any selected file has its
+name preceded by an asterisk.
+
+To check what is marked or not marked, enter the {\bf count} command, which
+displays:
+
+\footnotesize
+\begin{verbatim}
+128401 total files. 128401 marked to be restored.
+
+\end{verbatim}
+\normalsize
+
+Each of the above commands will be described in more detail in the next
+section. We continue with the above example, having accepted to restore all
+files as Bacula set by default. On entering the {\bf done} command, Bacula
+prints:
+

+\normalsize
+
+Please examine each of the items very carefully to make sure that they are
+correct. In particular, look at {\bf Where}, which tells you where in the
+directory structure the files will be restored, and {\bf Client}, which
+tells you which client will receive the files. Note that by default the
+Client which will receive the files is the Client that was backed up.
+These items will not always be completed with the correct values depending
+on which of the restore options you chose. You can change any of these
+default items by entering {\bf mod} and responding to the prompts.
+
+The above assumes that you have defined a {\bf Restore} Job resource in your
+Director's configuration file. Normally, you will only need one Restore Job
+resource definition because by its nature, restoring is a manual operation,
+and using the Console interface, you will be able to modify the Restore Job to
+do what you want.
+
+An example Restore Job resource definition is given below.
+
+Returning to the above example, you should verify that the Client name is
+correct before running the Job. However, you may want to modify some of the
+parameters of the restore job. For example, in addition to checking the Client
+it is wise to check that the Storage device chosen by Bacula is indeed
+correct. Although the {\bf FileSet} is shown, it will be ignored in restore.
+The restore will choose the files to be restored either by reading the {\bf
+Bootstrap} file, or if not specified, it will restore all files associated
+with the specified backup {\bf JobId} (i.e. the JobId of the Job that
+originally backed up the files).
+
+Finally before running the job, please note that the default location for
+restoring files is {\bf not} their original locations, but rather the directory
+{\bf /tmp/bacula-restores}. You can change this default by modifying your {\bf
+bacula-dir.conf} file, or you can modify it using the {\bf mod} option. If you
+want to restore the files to their original location, you must have {\bf
+Where} set to nothing or to the root, i.e. {\bf /}.
+
+If you now enter {\bf yes}, Bacula will run the restore Job. The Storage
+daemon will first request Volume {\bf DLT-19Jul02} and after the appropriate
+files have been restored from that volume, it will request Volume {\bf
+DLT-04Aug02}.
+
+\subsection{Restore a pruned job using a pattern}
+ During a restore, if all File records are pruned from the catalog
+ for a Job, normally Bacula can restore only all files saved. That
+ is there is no way using the catalog to select individual files.
+ With this new feature, Bacula will ask if you want to specify a Regex
+ expression for extracting only a part of the full backup.
+
+\begin{verbatim}
+ Building directory tree for JobId(s) 1,3 ...
+ There were no files inserted into the tree, so file selection
+ is not possible.Most likely your retention policy pruned the files
+
+ Do you want to restore all the files? (yes|no): no
+
+ Regexp matching files to restore? (empty to abort): /tmp/regress/(bin|tests)/
+ Bootstrap records written to /tmp/regress/working/zog4-dir.restore.1.bsr
+\end{verbatim}
+
+ See also \ilink{FileRegex bsr option}{FileRegex} for more information.

+\section{Selecting Files by Filename}
+\index[general]{Selecting Files by Filename }
+\index[general]{Filename!Selecting Files by }
+
+If you have a small number of files to restore, and you know the filenames,
+you can either put the list of filenames in a file to be read by Bacula, or
+you can enter the names one at a time. The filenames must include the full
+path and filename. No wild cards are used.
+
+To enter the files, after the {\bf restore}, you select item number 7 from the
+prompt list:
+
+\footnotesize
+\begin{verbatim}
+To select the JobIds, you have the following choices:
+ 1: List last 20 Jobs run
+ 2: List Jobs where a given File is saved
+ 3: Enter list of comma separated JobIds to select
+ 4: Enter SQL list command
+ 5: Select the most recent backup for a client
+ 6: Select backup for a client before a specified time
+ 7: Enter a list of files to restore
+ 8: Enter a list of files to restore before a specified time
+ 9: Find the JobIds of the most recent backup for a client
+ 10: Find the JobIds for a backup for a client before a specified time
+ 11: Enter a list of directories to restore for found JobIds
+ 12: Cancel
+Select item: (1-12):
+\end{verbatim}
+\normalsize
+
+which then prompts you for the client name:
+
+\footnotesize
+\begin{verbatim}
+Defined Clients:
+ 1: Timmy
+ 2: Tibs
+ 3: Rufus
+Select the Client (1-3): 3
+\end{verbatim}
+\normalsize
+
+Of course, your client list will be different, and if you have only one
+client, it will be automatically selected. And finally, Bacula requests you to
+enter a filename:
+
+\footnotesize
+\begin{verbatim}
+Enter filename:
+\end{verbatim}
+\normalsize
+
+At this point, you can enter the full path and filename
+
+\footnotesize
+\begin{verbatim}
+Enter filename: /home/kern/bacula/k/Makefile.in
+Enter filename:
+\end{verbatim}
+\normalsize
+
+as you can see, it took the filename. If Bacula cannot find a copy of the
+file, it prints the following:
+
+\footnotesize
+\begin{verbatim}
+Enter filename: junk filename
+No database record found for: junk filename
+Enter filename:
+\end{verbatim}
+\normalsize
+
+If you want Bacula to read the filenames from a file, you simply precede the
+filename with a less-than symbol (\lt{}). When you have entered all the
+filenames, you enter a blank line, and Bacula will write the bootstrap file,
+tells you what tapes will be used, and proposes a Restore job to be run:
+
+\footnotesize
+\begin{verbatim}
+Enter filename:
+Automatically selected Storage: DDS-4
+Bootstrap records written to /home/kern/bacula/working/restore.bsr
+The restore job will require the following Volumes:
+
+ test1
+1 file selected to restore.
+Run Restore job
+JobName: kernsrestore
+Bootstrap: /home/kern/bacula/working/restore.bsr
+Where: /tmp/bacula-restores
+Replace: always
+FileSet: Other Files
+Client: Rufus
+Storage: DDS-4
+When: 2003-09-11 10:20:53
+Priority: 10
+OK to run? (yes/mod/no):
+\end{verbatim}
+\normalsize
+
+It is possible to automate the selection by file by putting your list of files
+in say {\bf /tmp/file-list}, then using the following command:
+
+\footnotesize
+\begin{verbatim}
+restore client=Rufus file=</tmp/file-list
+\end{verbatim}
+\normalsize
+
+If in modifying the parameters for the Run Restore job, you find that Bacula
+asks you to enter a Job number, this is because you have not yet specified
+either a Job number or a Bootstrap file. Simply entering zero will allow you
+to continue and to select another option to be modified.
+
+\label{Replace}
+
+\section{Replace Options}
+
+When restoring, you have the option to specify a Replace option. This
+directive determines the action to be taken when restoring a file or
+directory that already exists. This directive can be set by selecting
+the {\bf mod} option. You will be given a list of parameters to choose
+from. Full details on this option can be found in the Job Resource section
+of the Director documentation.
+
+\label{CommandArguments}
+
+\section{Command Line Arguments}
+\index[general]{Arguments!Command Line }
+\index[general]{Command Line Arguments }
+
+If all the above sounds complicated, you will probably agree that it really
+isn't after trying it a few times. It is possible to do everything that was
+shown above, with the exception of selecting the FileSet, by using command
+line arguments with a single command by entering:
+
+\footnotesize
+\begin{verbatim}
+restore client=Rufus select current all done yes
+\end{verbatim}
+\normalsize
+
+The {\bf client=Rufus} specification will automatically select Rufus as the
+client, the {\bf current} tells Bacula that you want to restore the system to
+the most current state possible, and the {\bf yes} suppresses the final {\bf
+yes/mod/no} prompt and simply runs the restore.
+
+The full list of possible command line arguments are:
+
+\begin{itemize}
+\item {\bf all} -- select all Files to be restored.
+\item {\bf select} -- use the tree selection method.
+\item {\bf done} -- do not prompt the user in tree mode.
+\item {\bf current} -- automatically select the most current set of backups
+ for the specified client.
+\item {\bf client=xxxx} -- initially specifies the client from which the
+ backup was made and the client to which the restore will be make. See also
+ "restoreclient" keyword.
+\item {\bf restoreclient=xxxx} -- if the keyword is specified, then the
+ restore is written to that client.
+\item {\bf jobid=nnn} -- specify a JobId or comma separated list of JobIds to
+ be restored.
+\item {\bf before=YYYY-MM-DD HH:MM:SS} -- specify a date and time to which
+ the system should be restored. Only Jobs started before the specified
+ date/time will be selected, and as is the case for {\bf current} Bacula will
+ automatically find the most recent prior Full save and all Differential and
+ Incremental saves run before the date you specify. Note, this command is not
+ too user friendly in that you must specify the date/time exactly as shown.
+\item {\bf file=filename} -- specify a filename to be restored. You must
+ specify the full path and filename. Prefixing the entry with a less-than
+ sign
+ (\lt{}) will cause Bacula to assume that the filename is on your system and
+ contains a list of files to be restored. Bacula will thus read the list from
+ that file. Multiple file=xxx specifications may be specified on the command
+ line.
+\item {\bf jobid=nnn} -- specify a JobId to be restored.
+\item {\bf pool=pool-name} -- specify a Pool name to be used for selection of
+ Volumes when specifying options 5 and 6 (restore current system, and restore
+ current system before given date). This permits you to have several Pools,
+ possibly one offsite, and to select the Pool to be used for restoring.
+\item {\bf where=/tmp/bacula-restore} -- restore files in {\bf where} directory.
+\item {\bf yes} -- automatically run the restore without prompting for
+ modifications (most useful in batch scripts).
+\item {\bf strip\_prefix=/prod} -- remove a part of the filename when restoring.
+\item {\bf add\_prefix=/test} -- add a prefix to all files when restoring (like
+ where) (can't be used with {\bf where=}).
+\item {\bf add\_suffix=.old} -- add a suffix to all your files.
+\item {\bf regexwhere=!a.pdf!a.bkp.pdf!} -- do complex filename manipulation
+ like with sed unix command. Will overwrite other filename manipulation.
+\end{itemize}

+\section{Using File Relocation}
+\index[general]{Using File Relocation}
+\label{filerelocation}
+
+\subsection{Introduction}
+
+The \textbf{where=} option is simple, but not very powerful. With file
+relocation, Bacula can restore a file to the same directory, but with a
+different name, or in an other directory without recreating the full path.
+
+You can also do filename and path manipulations, implemented in Bacula
+2.1.8 or later, such as adding a suffix to all your files, renaming files
+or directories, etc. Theses options will overwrite {\bf where=} option.
+
+
+For example, many users use OS snapshot features so that file
+\texttt{/home/eric/mbox} will be backed up from the directory
+\texttt{/.snap/home/eric/mbox}, which can complicate restores. If you use
+\textbf{where=/tmp}, the file will be restored to
+\texttt{/tmp/.snap/home/eric/mbox} and you will have to move the file to
+\texttt{/home/eric/mbox.bkp} by hand.
+
+However, case, you could use the
+\textbf{strip\_prefix=/.snap} and \textbf{add\_suffix=.bkp} options and
+Bacula will restore the file to its original location -- that is
+\texttt{/home/eric/mbox}.
+
+To use this feature, there are command line options as described in
+the \ilink{restore section}{restorefilerelocation} of this manual;
+you can modify your restore job before running it; or you can
+add options to your restore job in as described in
+\ilink{bacula-dir.conf}{confaddprefix}.
+
+\begin{verbatim}
+Parameters to modify:
+ 1: Level
+ 2: Storage
+ ...
+ 10: File Relocation
+ ...
+Select parameter to modify (1-12):
+
+
+This will replace your current Where value
+ 1: Strip prefix
+ 2: Add prefix
+ 3: Add file suffix
+ 4: Enter a regexp
+ 5: Test filename manipulation
+ 6: Use this ?
+Select parameter to modify (1-6):
+\end{verbatim}
+
+
+\subsection{RegexWhere Format}
+
+The format is very close to that used by sed or Perl (\texttt{s/replace this/by
+ that/}) operator. A valid regexwhere expression has three fields :
+\begin{itemize}
+\item a search expression (with optionnal submatch)
+\item a replacement expression (with optionnal back references \$1 to \$9)
+\item a set of search options (only case-insensitive ``i'' at this time)
+\end{itemize}
+
+Each field is delimited by a separator specified by the user as the first
+character of the expression. The separator can be one of the following:
+\begin{verbatim}
+<separator-keyword> = / ! ; % : , ~ # = &
+\end{verbatim}
+
+You can use several expressions separated by a commas.
+
+\subsection*{Examples}
+
+\begin{tabular}{|c|c|c|l|}
+\hline
+Orignal filename & New filename & RegexWhere & Comments \\
+\hline
+\hline
+\texttt{c:/system.ini} & \texttt{c:/system.old.ini} & \texttt{/.ini\$/.old.ini/} & \$ matches end of name\\
+\hline
+\texttt{/prod/u01/pdata/} & \texttt{/rect/u01/rdata} & \texttt{/prod/rect/,/pdata/rdata/} & uses two regexp\\
+\hline
+\texttt{/prod/u01/pdata/} & \texttt{/rect/u01/rdata} & \texttt{!/prod/!/rect/!,/pdata/rdata/} & use \texttt{!} as separator\\
+\hline
+\texttt{C:/WINNT} & \texttt{d:/WINNT} & \texttt{/c:/d:/i} & case insensitive pattern match \\
+\hline
+
+\end{tabular}

+\section{Restoring Directory Attributes}
+\index[general]{Attributes!Restoring Directory }
+\index[general]{Restoring Directory Attributes }
+
+Depending how you do the restore, you may or may not get the directory entries
+back to their original state. Here are a few of the problems you can
+encounter, and for same machine restores, how to avoid them.
+
+\begin{itemize}
+\item You backed up on one machine and are restoring to another that is
+ either a different OS or doesn't have the same users/groups defined. Bacula
+ does the best it can in these situations. Note, Bacula has saved the
+ user/groups in numeric form, which means on a different machine, they
+ may map to different user/group names.
+
+\item You are restoring into a directory that is already created and has
+ file creation restrictions. Bacula tries to reset everything but
+ without walking up the full chain of directories and modifying them all
+ during the restore, which Bacula does and will not do, getting
+ permissions back correctly in this situation depends to a large extent
+ on your OS.
+
+\item You are doing a recursive restore of a directory tree. In this case
+ Bacula will restore a file before restoring the file's parent directory
+ entry. In the process of restoring the file Bacula will create the
+ parent directory with open permissions and ownership of the file being
+ restored. Then when Bacula tries to restore the parent directory Bacula
+ sees that it already exists (Similar to the previous situation). If you
+ had set the Restore job's "Replace" property to "never" then Bacula will
+ not change the directory's permissions and ownerships to match what it
+ backed up, you should also notice that the actual number of files
+ restored is less then the expected number. If you had set the Restore
+ job's "Replace" property to "always" then Bacula will change the
+ Directory's ownership and permissions to match what it backed up, also
+ the actual number of files restored should be equal to the expected
+ number.
+
+\item You selected one or more files in a directory, but did not select the
+ directory entry to be restored. In that case, if the directory is not
+ on disk Bacula simply creates the directory with some default attributes
+ which may not be the same as the original. If you do not select a
+ directory and all its contents to be restored, you can still select
+ items within the directory to be restored by individually marking those
+ files, but in that case, you should individually use the "markdir"
+ command to select all higher level directory entries (one at a time) to
+ be restored if you want the directory entries properly restored.
+
+\item The {\bf bextract} program does not restore access control lists
+ (ACLs), nor will it restore non-portable Win32 data (default) to Unix
+ machines.
+\end{itemize}
+
+\label{Windows}
+\section{Restoring on Windows}
+\index[general]{Restoring on Windows }
+\index[general]{Windows!Restoring on }
+
+If you are restoring on WinNT/2K/XP systems, Bacula will restore the files
+with the original ownerships and permissions as would be expected. This is
+also true if you are restoring those files to an alternate directory (using
+the Where option in restore). However, if the alternate directory does not
+already exist, the Bacula File daemon (Client) will try to create it. In
+some cases, it may not create the directories, and if it does since the
+File daemon runs under the SYSTEM account, the directory will be created
+with SYSTEM ownership and permissions. In this case, you may have problems
+accessing the newly restored files.
+
+To avoid this problem, you should create any alternate directory before
+doing the restore. Bacula will not change the ownership and permissions of
+the directory if it is already created as long as it is not one of the
+directories being restored (i.e. written to tape).
+
+The default restore location is {\bf /tmp/bacula-restores/} and if you are
+restoring from drive {\bf E:}, the default will be
+{\bf /tmp/bacula-restores/e/}, so you should ensure that this directory
+exists before doing the restore, or use the {\bf mod} option to
+select a different {\bf where} directory that does exist.
+
+Some users have experienced problems restoring files that participate in
+the Active Directory. They also report that changing the userid under which
+Bacula (bacula-fd.exe) runs, from SYSTEM to a Domain Admin userid, resolves
+the problem.
+
+
+\section{Restoring Files Can Be Slow}
+\index[general]{Slow!Restoring Files Can Be }
+\index[general]{Restoring Files Can Be Slow }
+
+Restoring files is generally {\bf much} slower than backing them up for several
+reasons. The first is that during a backup the tape is normally already
+positioned and Bacula only needs to write. On the other hand, because restoring
+files is done so rarely, Bacula keeps only the start file and block on the
+tape for the whole job rather than on a file by file basis which would use
+quite a lot of space in the catalog.
+
+Bacula will forward space to the correct file mark on the tape for the Job,
+then forward space to the correct block, and finally sequentially read each
+record until it gets to the correct one(s) for the file or files you want to
+restore. Once the desired files are restored, Bacula will stop reading the
+tape.
+
+Finally, instead of just reading a file for backup, during the restore, Bacula
+must create the file, and the operating system must allocate disk space for
+the file as Bacula is restoring it.
+
+For all the above reasons the restore process is generally much slower than
+backing up (sometimes it takes three times as long).
+
+\section{Problems Restoring Files}
+\index[general]{Files!Problems Restoring }
+\index[general]{Problems Restoring Files }
+
+The most frequent problems users have restoring files are error messages such
+as:
+
+\footnotesize
+\begin{verbatim}
+04-Jan 00:33 z217-sd: RestoreFiles.2005-01-04_00.31.04 Error:
+block.c:868 Volume data error at 20:0! Short block of 512 bytes on
+device /dev/tape discarded.
+\end{verbatim}
+\normalsize
+
+or
+
+\footnotesize
+\begin{verbatim}
+04-Jan 00:33 z217-sd: RestoreFiles.2005-01-04_00.31.04 Error:
+block.c:264 Volume data error at 20:0! Wanted ID: "BB02", got ".".
+Buffer discarded.
+\end{verbatim}
+\normalsize
+
+Both these kinds of messages indicate that you were probably running your tape
+drive in fixed block mode rather than variable block mode. Fixed block mode
+will work with any program that reads tapes sequentially such as tar, but
+Bacula repositions the tape on a block basis when restoring files because this
+will speed up the restore by orders of magnitude when only a few files are being
+restored. There are several ways that you can attempt to recover from this
+unfortunate situation.
+
+Try the following things, each separately, and reset your Device resource to
+what it is now after each individual test:
+
+\begin{enumerate}
+\item Set "Block Positioning = no" in your Device resource and try the
+ restore. This is a new directive and untested.
+
+\item Set "Minimum Block Size = 512" and "Maximum Block Size = 512" and
+ try the restore. If you are able to determine the block size your drive
+ was previously using, you should try that size if 512 does not work.
+ This is a really horrible solution, and it is not at all recommended
+ to continue backing up your data without correcting this condition.
+ Please see the Tape Testing chapter for more on this.
+
+\item Try editing the restore.bsr file at the Run xxx yes/mod/no prompt
+ before starting the restore job and remove all the VolBlock statements.
+ These are what causes Bacula to reposition the tape, and where problems
+ occur if you have a fixed block size set for your drive. The VolFile
+ commands also cause repositioning, but this will work regardless of the
+ block size.
+
+\item Use bextract to extract the files you want -- it reads the Volume
+ sequentially if you use the include list feature, or if you use a .bsr
+ file, but remove all the VolBlock statements after the .bsr file is
+ created (at the Run yes/mod/no) prompt but before you start the restore.
+\end{enumerate}
+
+\section{Restore Errors}
+\index[general]{Errors!Restore}
+\index[general]{Restore Errors}
+
+There are a number of reasons why there may be restore errors or
+warning messages. Some of the more common ones are:
+
+\begin{description}
+
+\item [file count mismatch]
+ This can occur for the following reasons:
+ \begin{itemize}
+ \item You requested Bacula not to overwrite existing or newer
+ files.
+ \item A Bacula miscount of files/directories. This is an
+ on-going problem due to the complications of directories,
+ soft/hard link, and such. Simply check that all the files you
+ wanted were actually restored.
+ \end{itemize}
+
+\item [file size error]
+ When Bacula restores files, it checks that the size of the
+ restored file is the same as the file status data it saved
+ when starting the backup of the file. If the sizes do not
+ agree, Bacula will print an error message. This size mismatch
+ most often occurs because the file was being written as Bacula
+ backed up the file. In this case, the size that Bacula
+ restored will be greater than the status size. This often
+ happens with log files.
+
+ If the restored size is smaller, then you should be concerned
+ about a possible tape error and check the Bacula output as
+ well as your system logs.

+\label{Selection}
+
+\section{File Selection Commands}
+\index[general]{Commands!File Selection }
+\index[general]{File Selection Commands }
+
+After you have selected the Jobs to be restored and Bacula has created the
+in-memory directory tree, you will enter file selection mode as indicated by
+the dollar sign ({\bf \$}) prompt. While in this mode, you may use the
+commands listed above. The basic idea is to move up and down the in memory
+directory structure with the {\bf cd} command much as you normally do on the
+system. Once you are in a directory, you may select the files that you want
+restored. As a default no files are marked to be restored. If you wish to
+start with all files, simply enter: {\bf cd /} and {\bf mark *}. Otherwise
+proceed to select the files you wish to restore by marking them with the {\bf
+mark} command. The available commands are:
+
+\begin{description}
+
+\item [cd]
+ The {\bf cd} command changes the current directory to the argument
+ specified.
+ It operates much like the Unix {\bf cd} command. Wildcard specifications are
+ not permitted.
+
+ Note, on Windows systems, the various drives (c:, d:, ...) are treated like
+ a
+ directory within the file tree while in the file selection mode. As a
+ consequence, you must do a {\bf cd c:} or possibly in some cases a {\bf cd
+ C:} (note upper case) to get down to the first directory.
+
+\item [dir]
+ \index[dir]{dir }
+ The {\bf dir} command is similar to the {\bf ls} command, except that it
+ prints it in long format (all details). This command can be a bit slower
+ than
+ the {\bf ls} command because it must access the catalog database for the
+ detailed information for each file.
+
+\item [estimate]
+ \index[dir]{estimate }
+ The {\bf estimate} command prints a summary of the total files in the tree,
+ how many are marked to be restored, and an estimate of the number of bytes
+ to
+ be restored. This can be useful if you are short on disk space on the
+ machine
+ where the files will be restored.
+
+\item [find]
+ \index[dir]{find}
+ The {\bf find} command accepts one or more arguments and displays all files
+ in the tree that match that argument. The argument may have wildcards. It is
+ somewhat similar to the Unix command {\bf find / -name arg}.
+
+\item [ls]
+ The {\bf ls} command produces a listing of all the files contained in the
+ current directory much like the Unix {\bf ls} command. You may specify an
+ argument containing wildcards, in which case only those files will be
+ listed.
+
+ Any file that is marked to be restored will have its name preceded by an
+ asterisk ({\bf *}). Directory names will be terminated with a forward slash
+ ({\bf /}) to distinguish them from filenames.
+
+\item [lsmark]
+ \index[fd]{lsmark}
+ The {\bf lsmark} command is the same as the {\bf ls} except that it will
+ print only those files marked for extraction. The other distinction is that
+ it will recursively descend into any directory selected.
+
+\item [mark]
+ \index[dir]{mark}
+ The {\bf mark} command allows you to mark files to be restored. It takes a
+ single argument which is the filename or directory name in the current
+ directory to be marked for extraction. The argument may be a wildcard
+ specification, in which case all files that match in the current directory
+ are marked to be restored. If the argument matches a directory rather than a
+ file, then the directory and all the files contained in that directory
+ (recursively) are marked to be restored. Any marked file will have its name
+ preceded with an asterisk ({\bf *}) in the output produced by the {\bf ls}
+or
+ {\bf dir} commands. Note, supplying a full path on the mark command does not
+ work as expected to select a file or directory in the current directory.
+ Also, the {\bf mark} command works on the current and lower directories but
+ does not touch higher level directories.
+
+ After executing the {\bf mark} command, it will print a brief summary:
+
+\footnotesize
+\begin{verbatim}
+ No files marked.
+
+\end{verbatim}
+\normalsize
+
+ If no files were marked, or:
+
+\footnotesize
+\begin{verbatim}
+ nn files marked.
+
+\end{verbatim}
+\normalsize
+
+ if some files are marked.
+
+\item [unmark]
+ \index[dir]{unmark }
+ The {\bf unmark} is identical to the {\bf mark} command, except that it
+ unmarks the specified file or files so that they will not be restored. Note:
+ the {\bf unmark} command works from the current directory, so it does not
+ unmark any files at a higher level. First do a {\bf cd /} before the {\bf
+ unmark *} command if you want to unmark everything.
+
+\item [pwd]
+ \index[dir]{pwd }
+ The {\bf pwd} command prints the current working directory. It accepts no
+ arguments.
+
+\item [count]
+ \index[dir]{count }
+ The {\bf count} command prints the total files in the directory tree and the
+ number of files marked to be restored.
+
+\item [done]
+ \index[dir]{done }
+ This command terminates file selection mode.
+
+\item [exit]
+ \index[fd]{exit }
+ This command terminates file selection mode (the same as done).
+
+\item [quit]
+ \index[fd]{quit }
+ This command terminates the file selection and does not run the restore
+job.
+
+
+\item [help]
+ \index[fd]{help }
+ This command prints a summary of the commands available.
+
+\item [?]
+ This command is the same as the {\bf help} command.

+\section{Restoring When Things Go Wrong}
+\index[general]{Restoring When Things Go Wrong }
+\index[general]{Restoring Your Database}
+\index[general]{Database!Restoring}
+
+This and the following sections will try to present a few of the kinds of
+problems that can come up making restoring more difficult. We will try to
+provide a few ideas how to get out of these problem situations.
+In addition to what is presented here, there is more specific information
+on restoring a \ilink{Client}{restore_client} and your
+\ilink{Server}{restore_server} in the \ilink{Disaster Recovery Using
+Bacula}{RescueChapter} chapter of this manual.
+
+\begin{description}
+\item[Problem]
+ My database is broken.
+\item[Solution]
+ For SQLite, use the vacuum command to try to fix the database. For either
+ MySQL or PostgreSQL, see the vendor's documentation. They have specific tools
+ that check and repair databases, see the \ilink{database
+ repair}{DatabaseRepair} sections of this manual for links to vendor
+ information.
+
+ Assuming the above does not resolve the problem, you will need to restore
+ or rebuild your catalog. Note, if it is a matter of some
+ inconsistencies in the Bacula tables rather than a broken database, then
+ running \ilink{dbcheck}{dbcheck} might help, but you will need to ensure
+ that your database indexes are properly setup. Please see
+ the \ilink{Database Performance Issues}{DatabasePerformance} sections
+ of this manual for more details.
+
+\item[Problem]
+ How do I restore my catalog?
+\item[Solution with a Catalog backup]
+ If you have backed up your database nightly (as you should) and you
+ have made a bootstrap file, you can immediately load back your
+ database (or the ASCII SQL output). Make a copy of your current
+ database, then re-initialize it, by running the following scripts:
+\begin{verbatim}
+ ./drop_bacula_tables
+ ./make_bacula_tables
+\end{verbatim}
+ After re-initializing the database, you should be able to run
+ Bacula. If you now try to use the restore command, it will not
+ work because the database will be empty. However, you can manually
+ run a restore job and specify your bootstrap file. You do so
+ by entering the {bf run} command in the console and selecting the
+ restore job. If you are using the default bacula-dir.conf, this
+ Job will be named {\bf RestoreFiles}. Most likely it will prompt
+ you with something such as:
+
+\footnotesize
+\begin{verbatim}
+Run Restore job
+JobName: RestoreFiles
+Bootstrap: /home/kern/bacula/working/restore.bsr
+Where: /tmp/bacula-restores
+Replace: always
+FileSet: Full Set
+Client: rufus-fd
+Storage: File
+When: 2005-07-10 17:33:40
+Catalog: MyCatalog
+Priority: 10
+OK to run? (yes/mod/no):
+\end{verbatim}
+\normalsize
+
+ A number of the items will be different in your case. What you want to
+ do is: to use the mod option to change the Bootstrap to point to your
+ saved bootstrap file; and to make sure all the other items such as
+ Client, Storage, Catalog, and Where are correct. The FileSet is not
+ used when you specify a bootstrap file. Once you have set all the
+ correct values, run the Job and it will restore the backup of your
+ database, which is most likely an ASCII dump.
+
+ You will then need to follow the instructions for your
+ database type to recreate the database from the ASCII backup file.
+ See the \ilink {Catalog Maintenance}{CatMaintenanceChapter} chapter of
+ this manual for examples of the command needed to restore a
+ database from an ASCII dump (they are shown in the Compacting Your
+ XXX Database sections).
+
+ Also, please note that after you restore your database from an ASCII
+ backup, you do NOT want to do a {\bf make\_bacula\_tables} command, or
+ you will probably erase your newly restored database tables.
+
+
+\item[Solution with a Job listing]
+ If you did save your database but did not make a bootstrap file, then
+ recovering the database is more difficult. You will probably need to
+ use bextract to extract the backup copy. First you should locate the
+ listing of the job report from the last catalog backup. It has
+ important information that will allow you to quickly find your database
+ file. For example, in the job report for the CatalogBackup shown below,
+ the critical items are the Volume name(s), the Volume Session Id and the
+ Volume Session Time. If you know those, you can easily restore your
+ Catalog.
+
+\footnotesize
+\begin{verbatim}
+22-Apr 10:22 HeadMan: Start Backup JobId 7510,
+Job=CatalogBackup.2005-04-22_01.10.0
+22-Apr 10:23 HeadMan: Bacula 1.37.14 (21Apr05): 22-Apr-2005 10:23:06
+ JobId: 7510
+ Job: CatalogBackup.2005-04-22_01.10.00
+ Backup Level: Full
+ Client: Polymatou
+ FileSet: "CatalogFile" 2003-04-10 01:24:01
+ Pool: "Default"
+ Storage: "DLTDrive"
+ Start time: 22-Apr-2005 10:21:00
+ End time: 22-Apr-2005 10:23:06
+ FD Files Written: 1
+ SD Files Written: 1
+ FD Bytes Written: 210,739,395
+ SD Bytes Written: 210,739,521
+ Rate: 1672.5 KB/s
+ Software Compression: None
+ Volume name(s): DLT-22Apr05
+ Volume Session Id: 11
+ Volume Session Time: 1114075126
+ Last Volume Bytes: 1,428,240,465
+ Non-fatal FD errors: 0
+ SD Errors: 0
+ FD termination status: OK
+ SD termination status: OK
+ Termination: Backup OK
+\end{verbatim}
+\normalsize
+
+ From the above information, you can manually create a bootstrap file,
+ and then follow the instructions given above for restoring your database.
+ A reconstructed bootstrap file for the above backup Job would look
+ like the following:
+
+\footnotesize
+\begin{verbatim}
+Volume="DLT-22Apr05"
+VolSessionId=11
+VolSessionTime=1114075126
+FileIndex=1-1
+\end{verbatim}
+\normalsize
+
+ Where we have inserted the Volume name, Volume Session Id, and Volume
+ Session Time that correspond to the values in the job report. We've also
+ used a FileIndex of one, which will always be the case providing that
+ there was only one file backed up in the job.
+
+ The disadvantage of this bootstrap file compared to what is created when
+ you ask for one to be written, is that there is no File and Block
+ specified, so the restore code must search all data in the Volume to find
+ the requested file. A fully specified bootstrap file would have the File
+ and Blocks specified as follows:
+
+\footnotesize
+\begin{verbatim}
+Volume="DLT-22Apr05"
+VolSessionId=11
+VolSessionTime=1114075126
+VolFile=118-118
+VolBlock=0-4053
+FileIndex=1-1
+\end{verbatim}
+\normalsize
+
+ Once you have restored the ASCII dump of the database,
+ you will then to follow the instructions for your
+ database type to recreate the database from the ASCII backup file.
+ See the \ilink {Catalog Maintenance}{CatMaintenanceChapter} chapter of
+ this manual for examples of the command needed to restore a
+ database from an ASCII dump (they are shown in the Compacting Your
+ XXX Database sections).
+
+ Also, please note that after you restore your database from an ASCII
+ backup, you do NOT want to do a {\bf make\_bacula\_tables} command, or
+ you will probably erase your newly restored database tables.
+
+\item [Solution without a Job Listing]
+ If you do not have a job listing, then it is a bit more difficult.
+ Either you use the \ilink{bscan}{bscan} program to scan the contents
+ of your tape into a database, which can be very time consuming
+ depending on the size of the tape, or you can use the \ilink{bls}{bls}
+ program to list everything on the tape, and reconstruct a bootstrap
+ file from the bls listing for the file or files you want following
+ the instructions given above.
+
+ There is a specific example of how to use {\bf bls} below.
+
+\item [Problem]
+ I try to restore the last known good full backup by specifying
+ item 3 on the restore menu then the JobId to restore. Bacula
+ then reports:
+
+\footnotesize
+\begin{verbatim}
+ 1 Job 0 Files
+\end{verbatim}
+\normalsize
+ and restores nothing.
+
+\item[Solution]
+ Most likely the File records were pruned from the database either due
+ to the File Retention period expiring or by explicitly purging the
+ Job. By using the "llist jobid=nn" command, you can obtain all the
+ important information about the job:
+
+\footnotesize
+\begin{verbatim}
+llist jobid=120
+ JobId: 120
+ Job: save.2005-12-05_18.27.33
+ Job.Name: save
+ PurgedFiles: 0
+ Type: B
+ Level: F
+ Job.ClientId: 1
+ Client.Name: Rufus
+ JobStatus: T
+ SchedTime: 2005-12-05 18:27:32
+ StartTime: 2005-12-05 18:27:35
+ EndTime: 2005-12-05 18:27:37
+ JobTDate: 1133803657
+ VolSessionId: 1
+ VolSessionTime: 1133803624
+ JobFiles: 236
+ JobErrors: 0
+ JobMissingFiles: 0
+ Job.PoolId: 4
+ Pool.Name: Full
+ Job.FileSetId: 1
+ FileSet.FileSet: BackupSet
+\end{verbatim}
+\normalsize
+
+ Then you can find the Volume(s) used by doing:
+
+\footnotesize
+\begin{verbatim}
+sql
+select VolumeName from JobMedia,Media where JobId=1 and JobMedia.MediaId=Media.MediaId;
+\end{verbatim}
+\normalsize
+
+ Finally, you can create a bootstrap file as described in the previous
+ problem above using this information.
+
+ If you are using Bacula version 1.38.0 or greater, when you select
+ item 3 from the menu and enter the JobId, it will ask you if
+ you would like to restore all the files in the job, and it will
+ collect the above information and write the bootstrap file for
+ you.
+
+\item [Problem]
+ You don't have a bootstrap file, and you don't have the Job report for
+ the backup of your database, but you did backup the database, and you
+ know the Volume to which it was backed up.
+
+\item [Solution]
+ Either bscan the tape (see below for bscanning), or better use {\bf bls}
+ to find where it is on the tape, then use {\bf bextract} to
+ restore the database. For example,
+
+
+\footnotesize
+\begin{verbatim}
+./bls -j -V DLT-22Apr05 /dev/nst0
+\end{verbatim}
+\normalsize
+ Might produce the following output:
+\footnotesize
+\begin{verbatim}
+bls: butil.c:258 Using device: "/dev/nst0" for reading.
+21-Jul 18:34 bls: Ready to read from volume "DLT-22Apr05" on device "DLTDrive"
+(/dev/nst0).
+Volume Record: File:blk=0:0 SessId=11 SessTime=1114075126 JobId=0 DataLen=164
+...
+Begin Job Session Record: File:blk=118:0 SessId=11 SessTime=1114075126
+JobId=7510
+ Job=CatalogBackup.2005-04-22_01.10.0 Date=22-Apr-2005 10:21:00 Level=F Type=B
+End Job Session Record: File:blk=118:4053 SessId=11 SessTime=1114075126
+JobId=7510
+ Date=22-Apr-2005 10:23:06 Level=F Type=B Files=1 Bytes=210,739,395 Errors=0
+Status=T
+...
+21-Jul 18:34 bls: End of Volume at file 201 on device "DLTDrive" (/dev/nst0),
+Volume "DLT-22Apr05"
+21-Jul 18:34 bls: End of all volumes.
+\end{verbatim}
+\normalsize
+ Of course, there will be many more records printed, but we have indicated
+ the essential lines of output. From the information on the Begin Job and End
+ Job Session Records, you can reconstruct a bootstrap file such as the one
+ shown above.
+
+\item[Problem]
+ How can I find where a file is stored.
+\item[Solution]
+ Normally, it is not necessary, you just use the {\bf restore} command to
+ restore the most recently saved version (menu option 5), or a version
+ saved before a given date (menu option 8). If you know the JobId of the
+ job in which it was saved, you can use menu option 3 to enter that JobId.
+
+ If you would like to know the JobId where a file was saved, select
+ restore menu option 2.
+
+ You can also use the {\bf query} command to find information such as:
+\footnotesize
+\begin{verbatim}
+*query
+Available queries:
+ 1: List up to 20 places where a File is saved regardless of the
+directory
+ 2: List where the most recent copies of a file are saved
+ 3: List last 20 Full Backups for a Client
+ 4: List all backups for a Client after a specified time
+ 5: List all backups for a Client
+ 6: List Volume Attributes for a selected Volume
+ 7: List Volumes used by selected JobId
+ 8: List Volumes to Restore All Files
+ 9: List Pool Attributes for a selected Pool
+ 10: List total files/bytes by Job
+ 11: List total files/bytes by Volume
+ 12: List Files for a selected JobId
+ 13: List Jobs stored on a selected MediaId
+ 14: List Jobs stored for a given Volume name
+ 15: List Volumes Bacula thinks are in changer
+ 16: List Volumes likely to need replacement from age or errors
+Choose a query (1-16):
+\end{verbatim}
+\normalsize
+
+\item[Problem]
+ I didn't backup my database. What do I do now?
+\item[Solution]
+ This is probably the worst of all cases, and you will probably have
+ to re-create your database from scratch and then bscan in all your
+ Volumes, which is a very long, painful, and inexact process.
+
+There are basically three steps to take:
+
+\begin{enumerate}
+\item Ensure that your SQL server is running (MySQL or PostgreSQL)
+ and that the Bacula database (normally bacula) exists. See the
+ \ilink{Installation}{CreateDatabase} chapter of the manual.
+\item Ensure that the Bacula databases are created. This is also
+ described at the above link.
+\item Start and stop the Bacula Director using the propriate
+ bacula-dir.conf file so that it can create the Client and
+ Storage records which are not stored on the Volumes. Without these
+ records, scanning is unable to connect the Job records to the proper
+ client.
+\end{enumerate}
+
+When the above is complete, you can begin bscanning your Volumes. Please
+see the \ilink{bscan}{bscan} section of the Volume Utility Tools of this
+chapter for more details.

+\chapter{Data Spooling}
+\label{SpoolingChapter}
+\index[general]{Data Spooling }
+\index[general]{Spooling!Data }
+
+Bacula allows you to specify that you want the Storage daemon to initially
+write your data to disk and then subsequently to tape. This serves several
+important purposes.
+
+\begin{itemize}
+\item It takes a long time for data to come in from the File daemon during
+ an Incremental backup. If it is directly written to tape, the tape will
+ start and stop or shoe-shine as it is often called causing tape wear.
+ By first writing the data to disk, then writing it to tape, the tape can
+ be kept in continual motion.
+\item While the spooled data is being written to the tape, the despooling
+ process has exclusive use of the tape. This means that you can spool
+ multiple simultaneous jobs to disk, then have them very efficiently
+ despooled one at a time without having the data blocks from several jobs
+ intermingled, thus substantially improving the time needed to restore
+ files. While despooling, all jobs spooling continue running.
+\item Writing to a tape can be slow. By first spooling your data to disk,
+ you can often reduce the time the File daemon is running on a system,
+ thus reducing downtime, and/or interference with users. Of course, if
+ your spool device is not large enough to hold all the data from your
+ File daemon, you may actually slow down the overall backup.
+\end{itemize}
+
+Data spooling is exactly that "spooling". It is not a way to first write a
+"backup" to a disk file and then to a tape. When the backup has only been
+spooled to disk, it is not complete yet and cannot be restored until it is
+written to tape.
+
+Bacula version 1.39.x and later supports writing a backup
+to disk then later {\bf Migrating} or moving it to a tape (or any
+other medium). For
+details on this, please see the \ilink{Migration}{MigrationChapter} chapter
+of this manual for more details.
+
+The remainder of this chapter explains the various directives that you can use
+in the spooling process.
+
+\label{directives}
+\section{Data Spooling Directives}
+\index[general]{Directives!Data Spooling }
+\index[general]{Data Spooling Directives }
+
+The following directives can be used to control data spooling.
+
+\begin{itemize}
+\item To turn data spooling on/off at the Job level in the Job resource in
+ the Director's conf file (default {\bf no}).
+
+{\bf SpoolData = yes|no}
+
+\item To override the Job specification in a Schedule Run directive in the
+ Director's conf file.
+
+{\bf SpoolData = yes|no}
+
+\item To override the Job specification in a bconsole session using the \texttt{run}
+ command. Please note that this does {\bf not } refer to a configuration
+ statement, but to an argument for the run command.
+
+{\bf SpoolData=yes|no}
+
+\item To limit the the maximum spool file size for a particular job in the Job
+ resource
+
+{\bf Spool Size = size}
+ Where size is a the maximum spool size for this job specified in bytes.
+
+\item To limit the maximum total size of the spooled data for a particular
+ device. Specified in the Device resource of the Storage daemon's conf file
+ (default unlimited).
+
+{\bf Maximum Spool Size = size}
+ Where size is a the maximum spool size for all jobs specified in bytes.
+
+\item To limit the maximum total size of the spooled data for a particular
+ device for a single job. Specified in the Device Resource of the Storage
+ daemon's conf file (default unlimited).
+
+{\bf Maximum Job Spool Size = size}
+ Where size is the maximum spool file size for a single job specified in
+ bytes.
+
+\item To specify the spool directory for a particular device. Specified in
+ the Device Resource of the Storage daemon's conf file (default, the working
+ directory).
+
+{\bf Spool Directory = directory}
+\end{itemize}
+
+\label{warning}
+
+% TODO: fix this section name
+\section{!!! MAJOR WARNING !!!}
+\index[general]{WARNING! MAJOR }
+\index[general]{ MAJOR WARNING }
+
+Please be very careful to exclude the spool directory from any backup,
+otherwise, your job will write enormous amounts of data to the Volume, and
+most probably terminate in error. This is because in attempting to backup the
+spool file, the backup data will be written a second time to the spool file,
+and so on ad infinitum.
+
+Another advice is to always specify the maximum spool size so that your disk
+doesn't completely fill up. In principle, data spooling will properly detect a
+full disk, and despool data allowing the job to continue. However, attribute
+spooling is not so kind to the user. If the disk on which attributes are being
+spooled fills, the job will be canceled. In addition, if your working
+directory is on the same partition as the spool directory, then Bacula jobs
+will fail possibly in bizarre ways when the spool fills.
+
+\label{points}
+\section{Other Points}
+\index[general]{Points!Other }
+\index[general]{Other Points }
+
+\begin{itemize}
+\item When data spooling is enabled, Bacula automatically turns on attribute
+ spooling. In other words, it also spools the catalog entries to disk. This is
+ done so that in case the job fails, there will be no catalog entries
+ pointing to non-existent tape backups.
+\item Attribute despooling occurs near the end of a job. The Storage daemon
+ accumulates file attributes during the backup and sends them to the
+ Director at the end of the job. The Director then inserts the file
+ attributes into the catalog. During this insertion, the tape drive may
+ be inactive. When the file attribute insertion is completed, the job
+ terminates.
+\item Attribute spool files are always placed in the working directory of
+ the Storage daemon.
+\item When Bacula begins despooling data spooled to disk, it takes exclusive
+ use of the tape. This has the major advantage that in running multiple
+ simultaneous jobs at the same time, the blocks of several jobs will not be
+ intermingled.
+\item It probably does not make a lot of sense to enable data spooling if you
+ are writing to disk files.
+\item It is probably best to provide as large a spool file as possible to
+ avoid repeatedly spooling/despooling. Also, while a job is despooling to
+ tape, the File daemon must wait (i.e. spooling stops for the job while it is
+ despooling).
+\item If you are running multiple simultaneous jobs, Bacula will continue
+ spooling other jobs while one is despooling to tape, provided there is
+ sufficient spool file space.
+\end{itemize}

+\chapter{The Current State of Bacula}
+\label{StateChapter}
+\index[general]{Current State of Bacula }
+
+In other words, what is and what is not currently implemented and functional.
+
+\section{What is Implemented}
+\index[general]{Implemented!What}
+\index[general]{What is Implemented}
+
+\begin{itemize}
+\item Job Control
+ \begin{itemize}
+ \item Network backup/restore with centralized Director.
+ \item Internal scheduler for automatic
+ \ilink{Job}{JobDef} execution.
+ \item Scheduling of multiple Jobs at the same time.
+ \item You may run one Job at a time or multiple simultaneous Jobs
+ (sometimes called multiplexing).
+ \item Job sequencing using priorities.
+ \item \ilink{Console}{UADef} interface to the Director allowing complete
+ control. A shell, Qt4 GUI, GNOME GUI and wxWidgets GUI versions of
+ the Console program are available. Note, the Qt4 GUI program called
+ the Bacula Administration tool or bat, offers many additional
+ features over the shell program.
+ \end{itemize}
+
+\item Security
+ \begin{itemize}
+ \item Verification of files previously cataloged, permitting a Tripwire like
+ capability (system break-in detection).
+ \item CRAM-MD5 password authentication between each component (daemon).
+ \item Configurable
+ \ilink{TLS (SSL) communications encryption}{CommEncryption} between each
+ component.
+ \item Configurable
+ \ilink{Data (on Volume) encryption}{DataEncryption}
+ on a Client by Client basis.
+ \item Computation of MD5 or SHA1 signatures of the file data if requested.
+ \end{itemize}
+
+
+\item Restore Features
+ \begin{itemize}
+ \item Restore of one or more files selected interactively either for the
+ current backup or a backup prior to a specified time and date.
+ \item Restore of a complete system starting from bare metal. This is mostly
+ automated for Linux systems and partially automated for Solaris. See
+ \ilink{Disaster Recovery Using Bacula}{RescueChapter}. This is also
+ reported to work on Win2K/XP systems.
+ \item Listing and Restoration of files using stand-alone {\bf bls} and {\bf
+ bextract} tool programs. Among other things, this permits extraction of files
+ when Bacula and/or the catalog are not available. Note, the recommended way
+ to restore files is using the restore command in the Console. These programs
+ are designed for use as a last resort.
+ \item Ability to restore the catalog database rapidly by using bootstrap
+ files (previously saved).
+ \item Ability to recreate the catalog database by scanning backup Volumes
+ using the {\bf bscan} program.
+ \end{itemize}
+
+\item SQL Catalog
+ \begin{itemize}
+ \item Catalog database facility for remembering Volumes, Pools, Jobs, and
+ Files backed up.
+ \item Support for MySQL, PostgreSQL, and SQLite Catalog databases.
+ \item User extensible queries to the MySQL, PostgreSQL and SQLite databases.
+ \end{itemize}
+
+\item Advanced Volume and Pool Management
+ \begin{itemize}
+ \item Labeled Volumes, preventing accidental overwriting (at least by
+ Bacula).
+ \item Any number of Jobs and Clients can be backed up to a single Volume.
+ That is, you can backup and restore Linux, Unix, Sun, and Windows machines to
+ the same Volume.
+ \item Multi-volume saves. When a Volume is full, {\bf Bacula} automatically
+ requests the next Volume and continues the backup.
+ \item
+ \ilink{Pool and Volume}{PoolResource} library management
+ providing Volume flexibility (e.g. monthly, weekly, daily Volume sets, Volume
+ sets segregated by Client, ...).
+ \item Machine independent Volume data format. Linux, Solaris, and Windows
+ clients can all be backed up to the same Volume if desired.
+ \item The Volume data format is upwards compatible so that old Volumes
+ can always be read.
+ \item A flexible
+ \ilink{message}{MessagesChapter} handler including routing
+ of messages from any daemon back to the Director and automatic email
+ reporting.
+ \item Data spooling to disk during backup with subsequent write to tape from
+ the spooled disk files. This prevents tape "shoe shine" during
+ Incremental/Differential backups.
+ \end{itemize}
+
+\item Advanced Support for most Storage Devices
+ \begin{itemize}
+ \item Autochanger support using a simple shell interface that can interface
+ to virtually any autoloader program. A script for {\bf mtx} is provided.
+ \item Support for autochanger barcodes -- automatic tape labeling from
+ barcodes.
+ \item Automatic support for multiple autochanger magazines either using
+ barcodes or by reading the tapes.
+ \item Support for multiple drive autochangers.
+ \item Raw device backup/restore. Restore must be to the same device.
+ \item All Volume blocks (approximately 64K bytes) contain a data checksum.
+ \item Migration support -- move data from one Pool to another or
+ one Volume to another.
+ \item Supports writing to DVD.
+ \end{itemize}
+
+\item Multi-Operating System Support
+ \begin{itemize}
+ \item Programmed to handle arbitrarily long filenames and messages.
+ \item GZIP compression on a file by file basis done by the Client program if
+ requested before network transit.
+ \item Saves and restores POSIX ACLs on most OSes if enabled.
+ \item Access control lists for Consoles that permit restricting user access
+ to only their data.
+ \item Support for save/restore of files larger than 2GB.
+ \item Support for 64 bit machines, e.g. amd64, Sparc.
+ \item Support ANSI and IBM tape labels.
+ \item Support for Unicode filenames (e.g. Chinese) on Win32 machines on
+ version 1.37.28 and greater.
+ \item Consistent backup of open files on Win32 systems (WinXP, Win2003,
+ and Vista)
+ but not Win2000, using Volume Shadow Copy (VSS).
+ \item Support for path/filename lengths of up to 64K on Win32 machines
+ (unlimited on Unix/Linux machines).
+ \end{itemize}
+
+\item Miscellaneous
+ \begin{itemize}
+ \item Multi-threaded implementation.
+ \item A comprehensive and extensible
+ \ilink{configuration file}{DirectorChapter} for each daemon.

+\section{Advantages Over Other Backup Programs}
+\index[general]{Advantages of Bacula Over Other Backup Programs }
+\index[general]{Programs!Advantages of Bacula Over Other Backup }
+
+\begin{itemize}
+\item Since there is a client for each machine, you can backup
+ and restore clients of any type ensuring that all attributes
+ of files are properly saved and restored.
+\item It is also possible to backup clients without any client
+ software by using NFS or Samba. However, if possible, we
+ recommend running a Client File daemon on each machine to be
+ backed up.
+\item Bacula handles multi-volume backups.
+\item A full comprehensive SQL standard database of all files backed up. This
+ permits online viewing of files saved on any particular Volume.
+\item Automatic pruning of the database (removal of old records) thus
+ simplifying database administration.
+\item Any SQL database engine can be used making Bacula very flexible.
+ Drivers currently exist for MySQL, PostgreSQL, and SQLite.
+\item The modular but integrated design makes Bacula very scalable.
+\item Since Bacula uses client file servers, any database or
+ other application can be properly shutdown by Bacula using the
+ native tools of the system, backed up, then restarted (all
+ within a Bacula Job).
+\item Bacula has a built-in Job scheduler.
+\item The Volume format is documented and there are simple C programs to
+ read/write it.
+\item Bacula uses well defined (IANA registered) TCP/IP ports -- no rpcs, no
+ shared memory.
+\item Bacula installation and configuration is relatively simple compared to
+ other comparable products.
+\item According to one user Bacula is as fast as the big major commercial
+ applications.
+\item According to another user Bacula is four times as fast as another
+ commercial application, probably because that application stores its catalog
+ information in a large number of individual files rather than an SQL database
+ as Bacula does.
+\item Aside from several GUI administrative interfaces, Bacula has a
+ comprehensive shell administrative interface, which allows the
+ administrator to use tools such as ssh to administrate any part of
+ Bacula from anywhere (even from home).
+\item Bacula has a Rescue CD for Linux systems with the following features:
+ \begin{itemize}
+ \item You build it on your own system from scratch with one simple command:
+ make -- well, then make burn.
+ \item It uses your kernel
+ \item It captures your current disk parameters and builds scripts that allow
+ you to automatically repartition a disk and format it to put it back to what
+ you had before.
+ \item It has a script that will restart your networking (with the right IP
+ address)
+ \item It has a script to automatically mount your hard disks.
+ \item It has a full Bacula FD statically linked
+ \item You can easily add additional data/programs, ... to the disk.
+ \end{itemize}
+
+\end{itemize}
+
+\section{Current Implementation Restrictions}
+\index[general]{Current Implementation Restrictions }
+\index[general]{Restrictions!Current Implementation }
+
+\begin{itemize}
+\item If you have over 4 billion file entries stored in your database, the
+ database FileId is likely to overflow. This is a monster database, but still
+ possible. Bacula's FileId fields have been modified so that they can be
+ upgraded from 32 to 64 bits in version 1.39 or later, but you must
+ manually do so.
+\item Files deleted after a Full save will be included in a restoration. This
+ is typical for most similar backup programs (we have a project to
+ correct this).
+\item Bacula's Differential and Incremental backups are based on
+ time stamps. Consequently, if you move files into an existing
+ directory or move a whole directory into the backup fileset
+ after a Full backup, those files will probably not be backed
+ up by an Incremental save because they will have old dates.
+ You must explicitly update the date/time stamp on all moved
+ files (we have a project to correct this).
+\item File System Modules (configurable routines for
+ saving/restoring special files) are not yet implemented. However,
+ this feature is easily implemented using RunScripts.
+\item Bacula supports doing backups and restores to multiple
+ devices of different media type and multiple Storage daemons.
+ However, if you have backed up a job to multiple storage
+ devices, Bacula can do a restore from only one device, which
+ means that you will need to manually edit the bootstrap file
+ to split it into two restores if you split the backup across
+ storage devices. This restriction has been removed in version
+ 2.2.0 and later, but it is not yet fully tested.
+\item Bacula cannot restore two different jobs in the same
+ restore if those jobs were run simultaneously, unless you had
+ data spooling turned on and the spool file held the full
+ contents of both jobs. In other terms, Bacula cannot restore
+ two jobs in the same restore if the jobs' data blocks were
+ intermixed on the backup medium. This poses no restrictions
+ for normal backup jobs even if they are run simultaneously.
+\item Bacula can generally restore any backup made from a client
+ to any other client. However, if the architecture is significantly
+ different (i.e. 32 bit architecture to 64 bit or Win32 to Unix),
+ some restrictions may apply (e.g. Solaris door files do not exist
+ on other Unix/Linux machines; there are reports that Zlib compression
+ written with 64 bit machines does not always read correctly on a 32 bit
+ machine).
+\end{itemize}
+
+\section{Design Limitations or Restrictions}
+\index[general]{Restrictions!Design Limitations or }
+\index[general]{Design Limitations or Restrictions }
+
+\begin{itemize}
+\item Names (resource names, Volume names, and such) defined in Bacula
+ configuration files are limited to a fixed number of
+ characters. Currently the limit is defined as 127 characters. Note,
+ this does not apply to filenames, which may be arbitrarily long.
+\item Command line input to some of the stand alone tools -- e.g. btape,
+ bconsole is restricted to several hundred characters maximum.

+\chapter{Using Bacula catalog to grab information}
+\label{UseBaculaCatalogToExtractInformationChapter}
+\index[general]{Statistics}
+
+Bacula catalog contains lot of information about your IT infrastructure, how
+many files, their size, the number of video or music files etc. Using Bacula
+catalog during the day to get them permit to save resources on your servers.
+
+In this chapter, you will find tips and information to measure bacula
+efficiency and report statistics.
+
+\section{Job statistics}
+If you (or probably your boss) want to have statistics on your backups to
+provide some \textit{Service Level Agreement} indicators, you could use a few
+SQL queries on the Job table to report how many:
+
+\begin{itemize}
+\item jobs have run
+\item jobs have been successful
+\item files have been backed up
+\item ...
+\end{itemize}
+
+However, these statistics are accurate only if your job retention is greater
+than your statistics period. Ie, if jobs are purged from the catalog, you won't
+be able to use them.
+
+Now, you can use the \textbf{update stats [days=num]} console command to fill
+the JobHistory table with new Job records. If you want to be sure to take in
+account only \textbf{good jobs}, ie if one of your important job has failed but
+you have fixed the problem and restarted it on time, you probably want to
+delete the first \textit{bad} job record and keep only the successful one. For
+that simply let your staff do the job, and update JobHistory table after two or
+three days depending on your organization using the \textbf{[days=num]} option.
+
+These statistics records aren't used for restoring, but mainly for
+capacity planning, billings, etc.
+
+The Bweb interface provides a statistics module that can use this feature. You
+can also use tools like Talend or extract information by yourself.
+
+The \textbf{Statistics Retention = \lt{}time\gt{}} director directive defines
+the length of time that Bacula will keep statistics job records in the Catalog
+database after the Job End time. (In \texttt{JobHistory} table) When this time
+period expires, and if user runs \texttt{prune stats} command, Bacula will
+prune (remove) Job records that are older than the specified period.
+
+You can use the following Job resource in your nightly \textbf{BackupCatalog}
+job to maintain statistics.
+\begin{verbatim}
+Job {
+ Name = BackupCatalog
+ ...
+ RunScript {
+ Console = "update stats days=3"
+ Console = "prune stats yes"
+ RunsWhen = After
+ RunsOnClient = no
+ }
+}

+\chapter{Backup Strategies}
+\label{StrategiesChapter}
+\index[general]{Strategies!Backup }
+\index[general]{Backup Strategies }
+
+Although Recycling and Backing Up to Disk Volume have been discussed in
+previous chapters, this chapter is meant to give you an overall view of
+possible backup strategies and to explain their advantages and disadvantages.
+\label{Simple}
+
+\section{Simple One Tape Backup}
+\index[general]{Backup!Simple One Tape }
+\index[general]{Simple One Tape Backup }
+
+Probably the simplest strategy is to back everything up to a single tape and
+insert a new (or recycled) tape when it fills and Bacula requests a new one.
+
+\subsection{Advantages}
+\index[general]{Advantages }
+
+\begin{itemize}
+\item The operator intervenes only when a tape change is needed. (once a
+ month at my site).
+\item There is little chance of operator error because the tape is not
+ changed daily.
+\item A minimum number of tapes will be needed for a full restore. Typically
+ the best case will be one tape and worst two.
+\item You can easily arrange for the Full backup to occur a different night
+ of the month for each system, thus load balancing and shortening the backup
+ time.
+\end{itemize}
+
+\subsection{Disadvantages}
+\index[general]{Disadvantages }
+
+\begin{itemize}
+\item If your site burns down, you will lose your current backups, and in my
+ case about a month of data.
+\item After a tape fills and you have put in a blank tape, the backup will
+ continue, and this will generally happen during working hours.
+ \end{itemize}
+
+\subsection{Practical Details}
+\index[general]{Details!Practical }
+\index[general]{Practical Details }
+
+This system is very simple. When the tape fills and Bacula requests a new
+tape, you {\bf unmount} the tape from the Console program, insert a new tape
+and {\bf label} it. In most cases after the label, Bacula will automatically
+mount the tape and resume the backup. Otherwise, you simply {\bf mount} the
+tape.
+
+Using this strategy, one typically does a Full backup once a week followed by
+daily Incremental backups. To minimize the amount of data written to the tape,
+one can do a Full backup once a month on the first Sunday of the
+month, a Differential backup on the 2nd-5th Sunday of the month, and
+incremental backups the rest of the week.
+\label{Manual}
+
+\section{Manually Changing Tapes}
+\index[general]{Tapes!Manually Changing }
+\index[general]{Manually Changing Tapes }
+
+If you use the strategy presented above, Bacula will ask you to change the
+tape, and you will {\bf unmount} it and then remount it when you have inserted
+the new tape.
+
+If you do not wish to interact with Bacula to change each tape, there are
+several ways to get Bacula to release the tape:
+
+\begin{itemize}
+\item In your Storage daemon's Device resource, set
+ {\bf AlwaysOpen = no}
+ In this case, Bacula will release the tape after every job. If you run
+ several jobs, the tape will be rewound and repositioned to the end at the
+ beginning of every job. This is not very efficient, but does let you change
+ the tape whenever you want.
+\item Use a {\bf RunAfterJob} statement to run a script after your last job.
+ This could also be an {\bf Admin} job that runs after all your backup jobs.
+ The script could be something like:
+
+\footnotesize
+\begin{verbatim}
+ #!/bin/sh
+ /full-path/bconsole -c /full-path/bconsole.conf <<END_OF_DATA
+ release storage=your-storage-name
+ END_OF_DATA
+
+\end{verbatim}
+\normalsize
+
+In this example, you would have {\bf AlwaysOpen=yes}, but the {\bf release}
+command would tell Bacula to rewind the tape and on the next job assume the
+tape has changed. This strategy may not work on some systems, or on
+autochangers because Bacula will still keep the drive open.
+\item The final strategy is similar to the previous case except that you
+ would use the unmount command to force Bacula to release the drive. Then you
+ would eject the tape, and remount it as follows:
+
+\footnotesize
+\begin{verbatim}
+ #!/bin/sh
+ /full-path/bconsole -c /full-path/bconsole.conf <\<END_OF_DATA
+ unmount storage=your-storage-name
+ END_OF_DATA
+ # the following is a shell command
+ mt eject
+ /full-path/bconsole -c /full-path/bconsole.conf <<END_OF_DATA
+ mount storage=your-storage-name
+ END_OF_DATA
+
+\end{verbatim}
+\normalsize
+
+\end{itemize}
+
+\label{Daily}
+
+\section{Daily Tape Rotation}
+\index[general]{Rotation!Daily Tape }
+\index[general]{Daily Tape Rotation }
+
+This scheme is quite different from the one mentioned above in that a Full
+backup is done to a different tape every day of the week. Generally, the
+backup will cycle continuously through five or six tapes each week. Variations are
+to use a different tape each Friday, and possibly at the beginning of the
+month. Thus if backups are done Monday through Friday only, you need only five
+tapes, and by having two Friday tapes, you need a total of six tapes. Many sites
+run this way, or using modifications of it based on two week cycles or longer.
+
+
+\subsection{Advantages}
+\index[general]{Advantages }
+
+\begin{itemize}
+\item All the data is stored on a single tape, so recoveries are simple and
+ faster.
+\item Assuming the previous day's tape is taken offsite each day, a maximum
+ of one days data will be lost if the site burns down.
+ \end{itemize}
+
+\subsection{Disadvantages}
+\index[general]{Disadvantages }
+
+\begin{itemize}
+\item The tape must be changed every day requiring a lot of operator
+ intervention.
+\item More errors will occur because of human mistakes.
+\item If the wrong tape is inadvertently mounted, the Backup for that day
+ will not occur exposing the system to data loss.
+\item There is much more movement of the tape each day (rewinds) leading to
+ shorter tape drive life time.
+\item Initial setup of Bacula to run in this mode is more complicated than
+ the Single tape system described above.
+\item Depending on the number of systems you have and their data capacity, it
+ may not be possible to do a Full backup every night for time reasons or
+ reasons of tape capacity.
+\end{itemize}
+
+\subsection{Practical Details}
+\index[general]{Details!Practical }
+\index[general]{Practical Details }
+
+The simplest way to "force" Bacula to use a different tape each day is to
+define a different Pool for each day of the the week a backup is done. In
+addition, you will need to specify appropriate Job and File retention periods
+so that Bacula will relabel and overwrite the tape each week rather than
+appending to it. Nic Bellamy has supplied an actual working model of this
+which we include here.
+
+What is important is to create a different Pool for each day of the week, and
+on the {\bf run} statement in the Schedule, to specify which Pool is to be
+used. He has one Schedule that accomplishes this, and a second Schedule that
+does the same thing for the Catalog backup run each day after the main backup
+(Priorities were not available when this script was written). In addition, he
+uses a {\bf Max Start Delay} of 22 hours so that if the wrong tape is
+premounted by the operator, the job will be automatically canceled, and the
+backup cycle will re-synchronize the next day. He has named his Friday Pool
+{\bf WeeklyPool} because in that Pool, he wishes to have several tapes to be
+able to restore to a time older than one week.
+
+And finally, in his Storage daemon's Device resource, he has {\bf Automatic
+Mount = yes} and {\bf Always Open = No}. This is necessary for the tape
+ejection to work in his {\bf end\_of\_backup.sh} script below.
+
+For example, his bacula-dir.conf file looks like the following:
+
+\footnotesize
+\begin{verbatim}
+
+# /etc/bacula/bacula-dir.conf
+#
+# Bacula Director Configuration file
+#

+\chapter{Using Stunnel to Encrypt Communications}
+\label{StunnelChapter}
+\index[general]{Using Stunnel to Encrypt Communications to Clients }
+
+Prior to version 1.37, Bacula did not have built-in communications encryption.
+Please see the \ilink {TLS chapter}{CommEncryption} if you are using Bacula
+1.37 or greater.
+
+Without too much effort, it is possible to encrypt the communications
+between any of the daemons. This chapter will show you how to use {\bf
+stunnel} to encrypt communications to your client programs. We assume the
+Director and the Storage daemon are running on one machine that will be called
+{\bf server} and the Client or File daemon is running on a different machine
+called {\bf client}. Although the details may be slightly different, the same
+principles apply whether you are encrypting between Unix, Linux, or Win32
+machines. This example was developed between two Linux machines running
+stunnel version 4.04-4 on a Red Hat Enterprise 3.0 system.

+\section{Communications Ports Used}
+\index[general]{Used!Communications Ports }
+\index[general]{Communications Ports Used }
+
+First, you must know that with the standard Bacula configuration, the Director
+will contact the File daemon on port 9102. The File daemon then contacts the
+Storage daemon using the address and port parameters supplied by the Director.
+The standard port used will be 9103. This is the typical server/client view of
+the world, the File daemon is a server to the Director (i.e. listens for the
+Director to contact it), and the Storage daemon is a server to the File
+daemon.
+
+\section{Encryption}
+\index[general]{Encryption }
+
+The encryption is accomplished between the Director and the File daemon by
+using an stunnel on the Director's machine (server) to encrypt the data and to
+contact an stunnel on the File daemon's machine (client), which decrypts the
+data and passes it to the client.
+
+Between the File daemon and the Storage daemon, we use an stunnel on the File
+daemon's machine to encrypt the data and another stunnel on the Storage
+daemon's machine to decrypt the data.
+
+As a consequence, there are actually four copies of stunnel running, two on the
+server and two on the client. This may sound a bit complicated, but it really
+isn't. To accomplish this, we will need to construct four separate conf files
+for stunnel, and we will need to make some minor modifications to the
+Director's conf file. None of the other conf files need to be changed.
+
+\section{A Picture}
+\index[general]{Picture }
+
+Since pictures usually help a lot, here is an overview of what we will be
+doing. Don't worry about all the details of the port numbers and such for the
+moment.
+
+\footnotesize
+\begin{verbatim}

+
+\section{Certificates}
+\index[general]{Certificates }
+
+In order for stunnel to function as a server, which it does in our diagram for
+Stunnel 1 and Stunnel 4, you must have a certificate and the key. It is
+possible to keep the two in separate files, but normally, you keep them in one
+single .pem file. You may create this certificate yourself in which case, it
+will be self-signed, or you may have it signed by a CA.
+
+If you want your clients to verify that the server is in fact valid (Stunnel 2
+and Stunnel 3), you will need to have the server certificates signed by a CA
+(Certificate Authority), and you will need to have the CA's public certificate
+(contains the CA's public key).
+
+Having a CA signed certificate is {\bf highly} recommended if you are using
+your client across the Internet, otherwise you are exposed to the man in the
+middle attack and hence loss of your data.
+
+See below for how to create a self-signed certificate.
+
+\section{Securing the Data Channel}
+\index[general]{Channel!Securing the Data }
+\index[general]{Securing the Data Channel }
+
+To simplify things a bit, let's for the moment consider only the data channel.
+That is the connection between the File daemon and the Storage daemon, which
+takes place on port 9103. In fact, in a minimalist solution, this is the only
+connection that needs to be encrypted, because it is the one that transports your
+data. The connection between the Director and the File daemon is simply a
+control channel used to start the job and get the job status.
+
+Normally the File daemon will contact the Storage daemon on port 9103
+(supplied by the Director), so we need an stunnel that listens on port 9103 on
+the File daemon's machine, encrypts the data and sends it to the Storage
+daemon. This is depicted by Stunnel 2 above. Note that this stunnel is
+listening on port 9103 and sending to server:29103. We use port 29103 on the
+server because if we would send the data to port 9103, it would go directly to the
+Storage daemon, which doesn't understand encrypted data. On the server
+machine, we run Stunnel 4, which listens on port 29103, decrypts the data and
+sends it to the Storage daemon, which is listening on port 9103.
+
+\section{Data Channel Configuration}
+\index[general]{Modification of bacula-dir.conf for the Data Channel }
+\index[general]{baculoa-dir.conf!Modification for the Data Channel }
+
+The Storage resource of the bacula-dir.conf normally looks something like the
+following:
+
+\footnotesize
+\begin{verbatim}
+Storage {
+ Name = File
+ Address = server
+ SDPort = 9103
+ Password = storage_password
+ Device = File
+ Media Type = File
+}
+\end{verbatim}
+\normalsize
+
+Notice that this is running on the server machine, and it points the File
+daemon back to server:9103, which is where our Storage daemon is listening. We
+modify this to be:
+
+\footnotesize
+\begin{verbatim}
+Storage {
+ Name = File
+ Address = localhost
+ SDPort = 9103
+ Password = storage_password
+ Device = File
+ Media Type = File
+}
+\end{verbatim}
+\normalsize
+
+This causes the File daemon to send the data to the stunnel running on
+localhost (the client machine). We could have used client as the address as
+well.
+
+\section{Stunnel Configuration for the Data Channel}
+\index[general]{Stunnel Configuration for the Data Channel }
+
+In the diagram above, we see above Stunnel 2 that we use stunnel-fd2.conf on the
+client. A pretty much minimal config file would look like the following:
+
+\footnotesize
+\begin{verbatim}
+client = yes
+[29103]
+accept = localhost:9103
+connect = server:29103
+\end{verbatim}
+\normalsize
+
+The above config file does encrypt the data but it does not require a
+certificate, so it is subject to the man in the middle attack. The file I
+actually used, stunnel-fd2.conf, looked like this:
+
+\footnotesize
+\begin{verbatim}
+#
+# Stunnel conf for Bacula client -> SD
+#
+pid = /home/kern/bacula/bin/working/stunnel.pid
+#
+# A cert is not mandatory here. If verify=2, a
+# cert signed by a CA must be specified, and
+# either CAfile or CApath must point to the CA's
+# cert
+#
+cert = /home/kern/stunnel/stunnel.pem
+CAfile = /home/kern/ssl/cacert.pem
+verify = 2
+client = yes
+# debug = 7
+# foreground = yes
+[29103]
+accept = localhost:9103
+connect = server:29103
+\end{verbatim}
+\normalsize
+
+You will notice that I specified a pid file location because I ran stunnel
+under my own userid so I could not use the default, which requires root
+permission. I also specified a certificate that I have as well as verify level
+2 so that the certificate is required and verified, and I must supply the
+location of the CA (Certificate Authority) certificate so that the stunnel
+certificate can be verified. Finally, you will see that there are two lines
+commented out, which when enabled, produce a lot of nice debug info in the
+command window.
+
+If you do not have a signed certificate (stunnel.pem), you need to delete the
+cert, CAfile, and verify lines.
+
+Note that the stunnel.pem, is actually a private key and a certificate in a
+single file. These two can be kept and specified individually, but keeping
+them in one file is more convenient.
+
+The config file, stunnel-sd.conf, needed for Stunnel 4 on the server machine
+is:
+
+\footnotesize
+\begin{verbatim}
+#
+# Bacula stunnel conf for Storage daemon
+#
+pid = /home/kern/bacula/bin/working/stunnel.pid
+#
+# A cert is mandatory here, it may be self signed
+# If it is self signed, the client may not use
+# verify
+#
+cert = /home/kern/stunnel/stunnel.pem
+client = no
+# debug = 7
+# foreground = yes
+[29103]
+accept = 29103
+connect = 9103
+\end{verbatim}
+\normalsize
+
+\section{Starting and Testing the Data Encryption}
+\index[general]{Starting and Testing the Data Encryption }
+\index[general]{Encryption!Starting and Testing the Data }
+
+It will most likely be the simplest to implement the Data Channel encryption
+in the following order:
+
+\begin{itemize}
+\item Setup and run Bacula backing up some data on your client machine
+ without encryption.
+\item Stop Bacula.
+\item Modify the Storage resource in the Director's conf file.
+\item Start Bacula
+\item Start stunnel on the server with:
+
+ \footnotesize
+\begin{verbatim}
+ stunnel stunnel-sd.conf
+
+\end{verbatim}
+\normalsize
+
+\item Start stunnel on the client with:
+
+ \footnotesize
+\begin{verbatim}
+ stunnel stunnel-fd2.conf
+
+\end{verbatim}
+\normalsize
+
+\item Run a job.
+\item If it doesn't work, turn debug on in both stunnel conf files, restart
+ the stunnels, rerun the job, repeat until it works.
+ \end{itemize}
+
+\section{Encrypting the Control Channel}
+\index[general]{Channel!Encrypting the Control }
+\index[general]{Encrypting the Control Channel }
+
+The Job control channel is between the Director and the File daemon, and as
+mentioned above, it is not really necessary to encrypt, but it is good
+practice to encrypt it as well. The two stunnels that are used in this case
+will be Stunnel 1 and Stunnel 3 in the diagram above. Stunnel 3 on the server
+might normally listen on port 9102, but if you have a local File daemon, this
+will not work, so we make it listen on port 29102. It then sends the data to
+client:29102. Again we use port 29102 so that the stunnel on the client
+machine can decrypt the data before passing it on to port 9102 where the File
+daemon is listening.
+
+\section{Control Channel Configuration}
+\index[general]{Control Channel Configuration }
+
+We need to modify the standard Client resource, which would normally look
+something like:
+
+\footnotesize
+\begin{verbatim}
+Client {
+ Name = client-fd
+ Address = client
+ FDPort = 9102
+ Catalog = BackupDB
+ Password = "xxx"
+}
+\end{verbatim}
+\normalsize
+
+to be:
+
+\footnotesize
+\begin{verbatim}
+Client {
+ Name = client-fd
+ Address = localhost
+ FDPort = 29102
+ Catalog = BackupDB
+ Password = "xxx"
+}
+\end{verbatim}
+\normalsize
+
+This will cause the Director to send the control information to
+localhost:29102 instead of directly to the client.
+
+\section{Stunnel Configuration for the Control Channel}
+\index[general]{Config Files for stunnel to Encrypt the Control Channel }
+
+The stunnel config file, stunnel-dir.conf, for the Director's machine would
+look like the following:
+
+\footnotesize
+\begin{verbatim}
+#
+# Bacula stunnel conf for the Directory to contact a client
+#
+pid = /home/kern/bacula/bin/working/stunnel.pid
+#
+# A cert is not mandatory here. If verify=2, a
+# cert signed by a CA must be specified, and
+# either CAfile or CApath must point to the CA's
+# cert
+#
+cert = /home/kern/stunnel/stunnel.pem
+CAfile = /home/kern/ssl/cacert.pem
+verify = 2
+client = yes
+# debug = 7
+# foreground = yes
+[29102]
+accept = localhost:29102
+connect = client:29102
+\end{verbatim}
+\normalsize
+
+and the config file, stunnel-fd1.conf, needed to run stunnel on the Client
+would be:
+
+\footnotesize
+\begin{verbatim}
+#
+# Bacula stunnel conf for the Directory to contact a client
+#
+pid = /home/kern/bacula/bin/working/stunnel.pid
+#
+# A cert is not mandatory here. If verify=2, a

+#
+cert = /home/kern/stunnel/stunnel.pem
+CAfile = /home/kern/ssl/cacert.pem
+verify = 2
+client = yes
+# debug = 7
+# foreground = yes
+[29102]
+accept = localhost:29102
+connect = client:29102
+\end{verbatim}
+\normalsize
+
+\section{Starting and Testing the Control Channel}
+\index[general]{Starting and Testing the Control Channel }
+\index[general]{Channel!Starting and Testing the Control }
+
+It will most likely be the simplest to implement the Control Channel
+encryption in the following order:
+
+\begin{itemize}
+\item Stop Bacula.
+\item Modify the Client resource in the Director's conf file.
+\item Start Bacula
+\item Start stunnel on the server with:
+
+ \footnotesize
+\begin{verbatim}

+
+\section{Using stunnel to Encrypt to a Second Client}
+\index[general]{Using stunnel to Encrypt to a Second Client }
+\index[general]{Client!Using stunnel to Encrypt to a Second }
+
+On the client machine, you can just duplicate the setup that you have on the
+first client file for file and it should work fine.
+
+In the bacula-dir.conf file, you will want to create a second client pretty
+much identical to how you did for the first one, but the port number must be
+unique. We previously used:
+
+\footnotesize
+\begin{verbatim}
+Client {
+ Name = client-fd
+ Address = localhost
+ FDPort = 29102
+ Catalog = BackupDB
+ Password = "xxx"
+}
+\end{verbatim}
+\normalsize
+
+so for the second client, we will, of course, have a different name, and we
+will also need a different port. Remember that we used port 29103 for the
+Storage daemon, so for the second client, we can use port 29104, and the
+Client resource would look like:
+
+\footnotesize
+\begin{verbatim}
+Client {
+ Name = client2-fd
+ Address = localhost
+ FDPort = 29104
+ Catalog = BackupDB
+ Password = "yyy"
+}
+\end{verbatim}
+\normalsize
+
+Now, fortunately, we do not need a third stunnel to on the Director's machine,
+we can just add the new port to the config file, stunnel-dir.conf, to make:
+
+\footnotesize
+\begin{verbatim}
+#
+# Bacula stunnel conf for the Directory to contact a client
+#
+pid = /home/kern/bacula/bin/working/stunnel.pid
+#
+# A cert is not mandatory here. If verify=2, a
+# cert signed by a CA must be specified, and
+# either CAfile or CApath must point to the CA's
+# cert
+#
+cert = /home/kern/stunnel/stunnel.pem
+CAfile = /home/kern/ssl/cacert.pem
+verify = 2
+client = yes
+# debug = 7
+# foreground = yes
+[29102]
+accept = localhost:29102
+connect = client:29102
+[29104]
+accept = localhost:29102
+connect = client2:29102
+\end{verbatim}
+\normalsize
+
+There are no changes necessary to the Storage daemon or the other stunnel so
+that this new client can talk to our Storage daemon.
+
+\section{Creating a Self-signed Certificate}
+\index[general]{Creating a Self-signed Certificate }
+\index[general]{Certificate!Creating a Self-signed }
+
+You may create a self-signed certificate for use with stunnel that will permit
+you to make it function, but will not allow certificate validation. The .pem
+file containing both the certificate and the key can be made with the
+following, which I put in a file named {\bf makepem}:
+
+\footnotesize
+\begin{verbatim}
+#!/bin/sh
+#
+# Simple shell script to make a .pem file that can be used
+# with stunnel and Bacula
+#
+OPENSSL=openssl
+ umask 77
+ PEM1="/bin/mktemp openssl.XXXXXX"
+ PEM2="/bin/mktemp openssl.XXXXXX"
+ ${OPENSSL} req -newkey rsa:1024 -keyout $PEM1 -nodes \
+ -x509 -days 365 -out $PEM2
+ cat $PEM1 > stunnel.pem
+ echo "" >>stunnel.pem
+ cat $PEM2 >>stunnel.pem
+ rm $PEM1 $PEM2
+\end{verbatim}
+\normalsize
+
+The above script will ask you a number of questions. You may simply answer
+each of them by entering a return, or if you wish you may enter your own data.

+\section{Getting a CA Signed Certificate}
+\index[general]{Certificate!Getting a CA Signed }
+\index[general]{Getting a CA Signed Certificate }
+
+The process of getting a certificate that is signed by a CA is quite a bit
+more complicated. You can purchase one from quite a number of PKI vendors, but
+that is not at all necessary for use with Bacula.
+
+To get a CA signed
+certificate, you will either need to find a friend that has setup his own CA
+or to become a CA yourself, and thus you can sign all your own certificates.
+The book OpenSSL by John Viega, Matt Mesier \& Pravir Chandra from O'Reilly
+explains how to do it, or you can read the documentation provided in the
+Open-source PKI Book project at Source Forge:

+\index[general]{Supported Tape Drives }
+
+Bacula uses standard operating system calls (read, write, ioctl) to
+interface to tape drives. As a consequence, it relies on having a
+correctly written OS tape driver. Bacula is known to work perfectly well
+with SCSI tape drivers on FreeBSD, Linux, Solaris, and Windows machines,
+and it may work on other *nix machines, but we have not tested it.
+Recently there are many new drives that use IDE, ATAPI, or
+SATA interfaces rather than SCSI. On Linux the OnStream drive, which uses
+the OSST driver is one such
+example, and it is known to work with Bacula. In addition a number of such
+tape drives (i.e. OS drivers) seem to work on Windows systems. However,
+non-SCSI tape drives (other than the OnStream) that use ide-scis, ide-tape,
+or other non-scsi drivers do not function correctly with Bacula (or any
+other demanding tape application) as of today (April 2007). If you
+have purchased a non-SCSI tape drive for use with Bacula on Linux, there
+is a good chance that it will not work. We are working with the kernel
+developers to rectify this situation, but it will not be resolved in the
+near future.
+
+Even if your drive is on the list below, please check the
+\ilink{Tape Testing Chapter}{btape1} of this manual for
+procedures that you can use to verify if your tape drive will work with
+Bacula. If your drive is in fixed block mode, it may appear to work with
+Bacula until you attempt to do a restore and Bacula wants to position the
+tape. You can be sure only by following the procedures suggested above and
+testing.
+
+It is very difficult to supply a list of supported tape drives, or drives that
+are known to work with Bacula because of limited feedback (so if you use
+Bacula on a different drive, please let us know). Based on user feedback, the
+following drives are known to work with Bacula. A dash in a column means
+unknown:

+
+Previously OnStream IDE-SCSI tape drives did not work with Bacula. As of
+Bacula version 1.33 and the osst kernel driver version 0.9.14 or later, they
+now work. Please see the testing chapter as you must set a fixed block size.
+
+QIC tapes are known to have a number of particularities (fixed block size, and
+one EOF rather than two to terminate the tape). As a consequence, you will
+need to take a lot of care in configuring them to make them work correctly
+with Bacula.

+Unless you have patched the pthreads library on FreeBSD 4.11 systems, you will
+lose data when Bacula spans tapes. This is because the unpatched pthreads
+library fails to return a warning status to Bacula that the end of the tape is
+near. This problem is fixed in FreeBSD systems released after 4.11. Please see the

+\index[general]{Tape Specifications}
+If you want to know what tape drive to buy that will work with Bacula,
+we really cannot tell you. However, we can say that if you are going
+to buy a drive, you should try to avoid DDS drives. The technology is
+rather old and DDS tape drives need frequent cleaning. DLT drives are
+generally much better (newer technology) and do not need frequent
+cleaning.
+
+Below, you will find a table of DLT and LTO tape specifications that will
+give you some idea of the capacity and speed of modern tapes. The
+capacities that are listed are the native tape capacity without compression.
+All modern drives have hardware compression, and manufacturers often list
+compressed capacity using a compression ration of 2:1. The actual compression
+ratio will depend mostly on the data you have to backup, but I find that
+1.5:1 is a much more reasonable number (i.e. multiply the value shown in
+the table by 1.5 to get a rough average of what you will probably see).
+The transfer rates are rounded to the nearest GB/hr. All values are provided
+by various manufacturers.
+
+The Media Type is what is designated by the manufacturers and you are not
+required to use (but you may) the same name in your Bacula conf resources.

+If you have a older Red Hat Linux system running the 2.4.x kernel and you have
+the directory {\bf /lib/tls} installed on your system (normally by default),
+bacula will {\bf NOT} run. This is the new pthreads library and it is
+defective. You must remove this directory prior to running Bacula, or you can
+simply change the name to {\bf /lib/tls-broken}) then you must reboot your
+machine (one of the few times Linux must be rebooted). If you are not able to
+remove/rename /lib/tls, an alternative is to set the environment variable
+"LD\_ASSUME\_KERNEL=2.4.19" prior to executing Bacula. For this option, you do
+not need to reboot, and all programs other than Bacula will continue to use
+/lib/tls.
+The above mentioned {\bf /lib/tls} problem does not occur with Linux 2.6 kernels.

+\chapter{Bacula TLS -- Communications Encryption}
+\label{CommEncryption}
+\index[general]{TLS -- Communications Encryption}
+\index[general]{Communications Encryption}
+\index[general]{Encryption!Communications}
+\index[general]{Encryption!Transport}
+\index[general]{Transport Encryption}
+\index[general]{TLS}
+
+Bacula TLS (Transport Layer Security) is built-in network
+encryption code to provide secure network transport similar to
+that offered by {\bf stunnel} or {\bf ssh}. The data written to
+Volumes by the Storage daemon is not encrypted by this code.
+For data encryption, please see the \ilink{Data Encryption
+Chapter}{DataEncryption} of this manual.
+
+The Bacula encryption implementations were written by Landon Fuller.
+
+Supported features of this code include:
+\begin{itemize}
+\item Client/Server TLS Requirement Negotiation
+\item TLSv1 Connections with Server and Client Certificate
+Validation
+\item Forward Secrecy Support via Diffie-Hellman Ephemeral Keying
+\end{itemize}
+
+This document will refer to both "server" and "client" contexts. These
+terms refer to the accepting and initiating peer, respectively.
+
+Diffie-Hellman anonymous ciphers are not supported by this code. The
+use of DH anonymous ciphers increases the code complexity and places
+explicit trust upon the two-way CRAM-MD5 implementation. CRAM-MD5 is
+subject to known plaintext attacks, and it should be considered
+considerably less secure than PKI certificate-based authentication.
+
+Appropriate autoconf macros have been added to detect and use OpenSSL
+if enabled on the {\bf ./configure} line with {\bf \verb?--?with-openssl}
+
+\section{TLS Configuration Directives}
+Additional configuration directives have been added to all the daemons
+(Director, File daemon, and Storage daemon) as well as the various
+different Console programs.
+These new directives are defined as follows:
+
+\begin{description}
+\item [TLS Enable = \lt{}yes|no\gt{}]
+Enable TLS support. If TLS is not enabled, none of the other TLS directives
+have any effect. In other words, even if you set {\bf TLS Require = yes}
+you need to have TLS enabled or TLS will not be used.
+
+\item [TLS Require = \lt{}yes|no\gt{}]
+Require TLS connections. This directive is ignored unless {\bf TLS Enable}
+is set to {\bf yes}. If TLS is not required, and TLS is enabled, then
+Bacula will connect with other daemons either with or without TLS depending
+on what the other daemon requests. If TLS is enabled and TLS is required,
+then Bacula will refuse any connection that does not use TLS.
+
+\item [TLS Certificate = \lt{}Filename\gt{}]
+The full path and filename of a PEM encoded TLS certificate. It can be
+used as either a client or server certificate. PEM stands for Privacy
+Enhanced Mail, but in this context refers to how the certificates are
+encoded. It is used because PEM files are base64 encoded and hence ASCII
+text based rather than binary. They may also contain encrypted
+information.
+
+\item [TLS Key = \lt{}Filename\gt{}]
+The full path and filename of a PEM encoded TLS private key. It must
+correspond to the TLS certificate.
+
+\item [TLS Verify Peer = \lt{}yes|no\gt{}]
+Verify peer certificate. Instructs server to request and verify the
+client's x509 certificate. Any client certificate signed by a known-CA
+will be accepted unless the TLS Allowed CN configuration directive is used,
+in which case the client certificate must correspond to the Allowed
+Common Name specified. This directive is valid only for a server
+and not in a client context.
+
+\item [TLS Allowed CN = \lt{}string list\gt{}]
+Common name attribute of allowed peer certificates. If this directive is
+specified, all server certificates will be verified against this list. This
+can be used to ensure that only the CA-approved Director may connect.
+This directive may be specified more than once.
+
+\item [TLS CA Certificate File = \lt{}Filename\gt{}]
+The full path and filename specifying a
+PEM encoded TLS CA certificate(s). Multiple certificates are
+permitted in the file. One of \emph{TLS CA Certificate File} or \emph{TLS
+CA Certificate Dir} are required in a server context if \emph{TLS
+Verify Peer} (see above) is also specified, and are always required in a client
+context.
+
+\item [TLS CA Certificate Dir = \lt{}Directory\gt{}]
+Full path to TLS CA certificate directory. In the current implementation,
+certificates must be stored PEM encoded with OpenSSL-compatible hashes,
+which is the subject name's hash and an extension of {bf .0}.
+One of \emph{TLS CA Certificate File} or \emph{TLS CA Certificate Dir} are
+required in a server context if \emph{TLS Verify Peer} is also specified,
+and are always required in a client context.
+
+\item [TLS DH File = \lt{}Directory\gt{}]
+Path to PEM encoded Diffie-Hellman parameter file. If this directive is
+specified, DH key exchange will be used for the ephemeral keying, allowing
+for forward secrecy of communications. DH key exchange adds an additional
+level of security because the key used for encryption/decryption by the
+server and the client is computed on each end and thus is never passed over
+the network if Diffie-Hellman key exchange is used. Even if DH key
+exchange is not used, the encryption/decryption key is always passed
+encrypted. This directive is only valid within a server context.
+
+To generate the parameter file, you
+may use openssl:
+
+\begin{verbatim}
+ openssl dhparam -out dh1024.pem -5 1024
+\end{verbatim}
+
+\end{description}
+
+\section{Creating a Self-signed Certificate}
+\index[general]{Creating a Self-signed Certificate }
+\index[general]{Certificate!Creating a Self-signed }
+
+You may create a self-signed certificate for use with the Bacula TLS that
+will permit you to make it function, but will not allow certificate
+validation. The .pem file containing both the certificate and the key
+valid for ten years can be made with the following:
+
+\footnotesize
+\begin{verbatim}
+ openssl req -new -x509 -nodes -out bacula.pem -keyout bacula.pem -days 3650
+\end{verbatim}
+\normalsize
+
+The above script will ask you a number of questions. You may simply answer
+each of them by entering a return, or if you wish you may enter your own data.
+
+Note, however, that self-signed certificates will only work for the
+outgoing end of connections. For example, in the case of the Director
+making a connection to a File Daemon, the File Daemon may be configured to
+allow self-signed certificates, but the certificate used by the
+Director must be signed by a certificate that is explicitly trusted on the
+File Daemon end.
+
+This is necessary to prevent ``man in the middle'' attacks from tools such
+as \elink{ettercap}{http://ettercap.sourceforge.net/}. Essentially, if the
+Director does not verify that it is talking to a trusted remote endpoint,
+it can be tricked into talking to a malicious 3rd party who is relaying and
+capturing all traffic by presenting its own certificates to the Director
+and File Daemons. The only way to prevent this is by using trusted
+certificates, so that the man in the middle is incapable of spoofing the
+connection using his own.
+
+To get a trusted certificate (CA or Certificate Authority signed
+certificate), you will either need to purchase certificates signed by a
+commercial CA or find a friend that has setup his own CA or become a CA
+yourself, and thus you can sign all your own certificates. The book
+OpenSSL by John Viega, Matt Mesier \& Pravir Chandra from O'Reilly explains
+how to do it, or you can read the documentation provided in the Open-source
+PKI Book project at Source Forge: \elink{
+http://ospkibook.sourceforge.net/docs/OSPKI-2.4.7/OSPKI-html/ospki-book.htm}
+{http://ospkibook.sourceforge.net/docs/OSPKI-2.4.7/OSPKI-html/ospki-book.htm}.
+Note, this link may change.
+
+The program TinyCA has a very nice Graphical User Interface
+that allows you to easily setup and maintain your own CA.
+TinyCA can be found at
+\elink{http://tinyca.sm-zone.net/}{http://tinyca.sm-zone.net/}.
+
+
+\section{Getting a CA Signed Certificate}
+\index[general]{Certificate!Getting a CA Signed }
+\index[general]{Getting a CA Signed Certificate }
+
+The process of getting a certificate that is signed by a CA is quite a bit
+more complicated. You can purchase one from quite a number of PKI vendors, but
+that is not at all necessary for use with Bacula. To get a CA signed
+certificate, you will either need to find a friend that has setup his own CA
+or to become a CA yourself, and thus you can sign all your own certificates.
+The book OpenSSL by John Viega, Matt Mesier \& Pravir Chandra from O'Reilly
+explains how to do it, or you can read the documentation provided in the
+Open-source PKI Book project at Source Forge:

+\chapter{A Brief Tutorial}
+\label{TutorialChapter}
+\index[general]{Brief Tutorial }
+\index[general]{Tutorial!Brief }
+
+This chapter will guide you through running Bacula. To do so, we assume you
+have installed Bacula, possibly in a single file as shown in the previous
+chapter, in which case, you can run Bacula as non-root for these tests.
+However, we assume that you have not changed the .conf files. If you have
+modified the .conf files, please go back and uninstall Bacula, then reinstall
+it, but do not make any changes. The examples in this chapter use the default
+configuration files, and will write the volumes to disk in your {\bf /tmp}
+directory, in addition, the data backed up will be the source directory where
+you built Bacula. As a consequence, you can run all the Bacula daemons for
+these tests as non-root. Please note, in production, your File daemon(s) must
+run as root. See the Security chapter for more information on this subject.
+
+% TODO: use crossreferences above
+% TODO: add a section here
+
+The general flow of running Bacula is:
+
+\begin{enumerate}
+\item cd \lt{}install-directory\gt{}
+\item Start the Database (if using MySQL or PostgreSQL)
+\item Start the Daemons with {\bf ./bacula start}
+\item Start the Console program to interact with the Director
+\item Run a job
+\item When the Volume fills, unmount the Volume, if it is a tape, label a new
+ one, and continue running. In this chapter, we will write only to disk files
+ so you won't need to worry about tapes for the moment.
+\item Test recovering some files from the Volume just written to ensure the
+ backup is good and that you know how to recover. Better test before disaster
+ strikes
+\item Add a second client.
+ \end{enumerate}
+
+Each of these steps is described in more detail below.
+
+\section{Before Running Bacula}
+\index[general]{Bacula!Before Running }
+\index[general]{Before Running Bacula }
+
+% TODO: some of this content is already covered once or twice critical
+% TODO: or quickstart. Consolidate!
+
+Before running Bacula for the first time in production, we recommend that you
+run the {\bf test} command in the {\bf btape} program as described in the
+\ilink{Utility Program Chapter}{btape} of this manual. This will
+help ensure that Bacula functions correctly with your tape drive. If you have
+a modern HP, Sony, or Quantum DDS or DLT tape drive running on Linux or
+Solaris, you can probably skip this test as Bacula is well tested with these
+drives and systems. For all other cases, you are {\bf strongly} encouraged to
+run the test before continuing. {\bf btape} also has a {\bf fill} command that
+attempts to duplicate what Bacula does when filling a tape and writing on the
+next tape. You should consider trying this command as well, but be forewarned,
+it can take hours (about four hours on my drive) to fill a large capacity tape.
+
+\section{Starting the Database}
+\label{StartDB}
+\index[general]{Starting the Database }
+\index[general]{Database!Starting the }
+
+If you are using MySQL or PostgreSQL as the Bacula database, you should start
+it before you attempt to run a job to avoid getting error messages from Bacula
+when it starts. The scripts {\bf startmysql} and {\bf stopmysql} are what I
+(Kern) use to start and stop my local MySQL. Note, if you are using SQLite,
+you will not want to use {\bf startmysql} or {\bf stopmysql}. If you are
+running this in production, you will probably want to find some way to
+automatically start MySQL or PostgreSQL after each system reboot.
+
+If you are using SQLite (i.e. you specified the {\bf \verb:--:with-sqlite=xxx} option
+on the {\bf ./configure} command, you need do nothing. SQLite is automatically
+started by {\bf Bacula}.
+
+\section{Starting the Daemons}
+\label{StartDaemon}
+\index[general]{Starting the Daemons }
+\index[general]{Daemons!Starting the }
+
+Assuming you have built from source or have installed the rpms,
+to start the three daemons, from your installation directory, simply enter:
+
+./bacula start
+
+The {\bf bacula} script starts the Storage daemon, the File daemon, and the
+Director daemon, which all normally run as daemons in the background. If you
+are using the autostart feature of Bacula, your daemons will either be
+automatically started on reboot, or you can control them individually with the
+files {\bf bacula-dir}, {\bf bacula-fd}, and {\bf bacula-sd}, which are
+usually located in {\bf /etc/init.d}, though the actual location is system
+dependent.
+Some distributions may do this differently.
+
+Note, on Windows, currently only the File daemon is ported, and it must be
+started differently. Please see the
+\ilink{Windows Version of Bacula}{Win32Chapter} Chapter of this
+manual.
+
+The rpm packages configure the daemons to run as user=root and group=bacula.
+The rpm installation also creates the group bacula if it does not exist on the
+system. Any users that you add to the group bacula will have access to files
+created by the daemons. To disable or alter this behavior edit the daemon
+startup scripts:
+
+\begin{itemize}
+\item /etc/bacula/bacula
+\item /etc/init.d/bacula-dir
+\item /etc/init.d/bacula-sd
+\item /etc/init.d/bacula-fd
+ \end{itemize}
+
+and then restart as noted above.
+
+The
+\ilink{installation chapter}{InstallChapter} of this manual
+explains how you can install scripts that will automatically restart the
+daemons when the system starts.
+
+\section{Using the Director to Query and Start Jobs}
+\index[general]{Jobs!Querying or Starting Jobs}
+\index[general]{Querying or starting Jobs}
+% TODO: section name is too long; maybe use "Using the Console Program" ??
+
+To communicate with the director and to query the state of Bacula or run jobs,
+from the top level directory, simply enter:
+
+./bconsole
+
+Alternatively to running the command line console, if you have
+Qt4 installed and used the {\bf \verb:--:enable-bat} on the configure command,
+you may use the Bacula Administration Tool ({\bf bat}):
+
+./bat
+
+Which has a graphical interface, and many more features than bconsole.
+
+Two other possibilities are to run the GNOME console
+{\bf bgnome-console} or the wxWidgets program {\bf bwx-console}.
+
+For simplicity, here we will describe only the {\bf ./bconsole} program. Most
+of what is described here applies equally well to {\bf ./bat},
+{\bf ./bgnome-console}, and to {\bf bwx-console}.
+
+The {\bf ./bconsole} runs the Bacula Console program, which connects to the
+Director daemon. Since Bacula is a network program, you can run the Console
+program anywhere on your network. Most frequently, however, one runs it on the
+same machine as the Director. Normally, the Console program will print
+something similar to the following:
+
+\footnotesize
+\begin{verbatim}
+[kern@polymatou bin]$ ./bconsole
+Connecting to Director lpmatou:9101
+1000 OK: HeadMan Version: 2.1.8 (14 May 2007)
+*
+\end{verbatim}
+\normalsize
+
+the asterisk is the console command prompt.
+
+Type {\bf help} to see a list of available commands:
+
+\footnotesize

+\section{Running a Job}
+\label{Running}
+\index[general]{Job!Running a }
+\index[general]{Running a Job }
+
+At this point, we assume you have done the following:
+
+\begin{itemize}
+\item Configured Bacula with {\bf ./configure \verb:--:your-options}
+\item Built Bacula using {\bf make}
+\item Installed Bacula using {\bf make install}
+\item Have created your database with, for example, {\bf
+ ./create\_sqlite\_database}
+\item Have created the Bacula database tables with, {\bf
+ ./make\_bacula\_tables}
+\item Have possibly edited your {\bf bacula-dir.conf} file to personalize it
+ a bit. BE CAREFUL! if you change the Director's name or password, you will
+ need to make similar modifications in the other .conf files. For the moment
+ it is probably better to make no changes.
+\item You have started Bacula with {\bf ./bacula start}
+\item You have invoked the Console program with {\bf ./bconsole}
+\end{itemize}
+
+Furthermore, we assume for the moment you are using the default configuration
+files.
+
+At this point, enter the following command:
+
+\footnotesize
+\begin{verbatim}
+show filesets
+\end{verbatim}
+\normalsize
+
+and you should get something similar to:
+
+\footnotesize
+\begin{verbatim}
+FileSet: name=Full Set
+ O M
+ N
+ I /home/kern/bacula/regress/build
+ N
+ E /proc
+ E /tmp
+ E /.journal
+ E /.fsck
+ N
+FileSet: name=Catalog
+ O M
+ N
+ I /home/kern/bacula/regress/working/bacula.sql
+ N
+\end{verbatim}
+\normalsize
+
+This is a pre-defined {\bf FileSet} that will backup the Bacula source
+directory. The actual directory names printed should correspond to your system
+configuration. For testing purposes, we have chosen a directory of moderate
+size (about 40 Megabytes) and complexity without being too big. The FileSet
+{\bf Catalog} is used for backing up Bacula's catalog and is not of interest
+to us for the moment. The {\bf I} entries are the files or directories that
+will be included in the backup and the {\bf E} are those that will be
+excluded, and the {\bf O} entries are the options specified for
+the FileSet. You can change what is backed up by editing {\bf bacula-dir.conf}
+and changing the {\bf File =} line in the {\bf FileSet} resource.
+
+Now is the time to run your first backup job. We are going to backup your
+Bacula source directory to a File Volume in your {\bf /tmp} directory just to
+show you how easy it is. Now enter:
+
+\footnotesize
+\begin{verbatim}
+status dir
+\end{verbatim}
+\normalsize
+
+and you should get the following output:
+
+\footnotesize
+\begin{verbatim}
+rufus-dir Version: 1.30 (28 April 2003)
+Daemon started 28-Apr-2003 14:03, 0 Jobs run.
+Console connected at 28-Apr-2003 14:03
+No jobs are running.
+Level Type Scheduled Name
+=================================================================
+Incremental Backup 29-Apr-2003 01:05 Client1
+Full Backup 29-Apr-2003 01:10 BackupCatalog
+====
+\end{verbatim}
+\normalsize
+
+where the times and the Director's name will be different according to your
+setup. This shows that an Incremental job is scheduled to run for the Job {\bf
+Client1} at 1:05am and that at 1:10, a {\bf BackupCatalog} is scheduled to
+run. Note, you should probably change the name {\bf Client1} to be the name of
+your machine, if not, when you add additional clients, it will be very
+confusing. For my real machine, I use {\bf Rufus} rather than {\bf Client1} as
+in this example.
+
+Now enter:
+
+\footnotesize
+\begin{verbatim}
+status client
+\end{verbatim}
+\normalsize
+
+and you should get something like:
+
+\footnotesize
+\begin{verbatim}
+The defined Client resources are:
+ 1: rufus-fd
+Item 1 selected automatically.
+Connecting to Client rufus-fd at rufus:8102
+rufus-fd Version: 1.30 (28 April 2003)
+Daemon started 28-Apr-2003 14:03, 0 Jobs run.
+Director connected at: 28-Apr-2003 14:14
+No jobs running.
+====
+\end{verbatim}
+\normalsize
+
+In this case, the client is named {\bf rufus-fd} your name will be different,
+but the line beginning with {\bf rufus-fd Version ...} is printed by your File
+daemon, so we are now sure it is up and running.
+
+Finally do the same for your Storage daemon with:
+
+\footnotesize
+\begin{verbatim}
+status storage
+\end{verbatim}
+\normalsize
+
+and you should get:
+
+\footnotesize
+\begin{verbatim}
+The defined Storage resources are:
+ 1: File
+Item 1 selected automatically.
+Connecting to Storage daemon File at rufus:8103
+rufus-sd Version: 1.30 (28 April 2003)
+Daemon started 28-Apr-2003 14:03, 0 Jobs run.
+Device /tmp is not open.
+No jobs running.
+====
+\end{verbatim}
+\normalsize
+
+You will notice that the default Storage daemon device is named {\bf File} and
+that it will use device {\bf /tmp}, which is not currently open.
+
+Now, let's actually run a job with:
+
+\footnotesize
+\begin{verbatim}
+run
+\end{verbatim}
+\normalsize
+
+you should get the following output:
+
+\footnotesize
+\begin{verbatim}
+Using default Catalog name=MyCatalog DB=bacula
+A job name must be specified.
+The defined Job resources are:
+ 1: Client1
+ 2: BackupCatalog
+ 3: RestoreFiles
+Select Job resource (1-3):
+\end{verbatim}
+\normalsize
+
+Here, Bacula has listed the three different Jobs that you can run, and you
+should choose number {\bf 1} and type enter, at which point you will get:
+
+\footnotesize
+\begin{verbatim}
+Run Backup job
+JobName: Client1
+FileSet: Full Set
+Level: Incremental
+Client: rufus-fd
+Storage: File
+Pool: Default
+When: 2003-04-28 14:18:57
+OK to run? (yes/mod/no):
+\end{verbatim}
+\normalsize
+
+At this point, take some time to look carefully at what is printed and
+understand it. It is asking you if it is OK to run a job named {\bf Client1}
+with FileSet {\bf Full Set} (we listed above) as an Incremental job on your
+Client (your client name will be different), and to use Storage {\bf File} and
+Pool {\bf Default}, and finally, it wants to run it now (the current time
+should be displayed by your console).
+
+Here we have the choice to run ({\bf yes}), to modify one or more of the above
+parameters ({\bf mod}), or to not run the job ({\bf no}). Please enter {\bf
+yes}, at which point you should immediately get the command prompt (an
+asterisk). If you wait a few seconds, then enter the command {\bf messages}
+you will get back something like:
+
+\footnotesize
+\begin{verbatim}
+28-Apr-2003 14:22 rufus-dir: Last FULL backup time not found. Doing
+ FULL backup.
+28-Apr-2003 14:22 rufus-dir: Start Backup JobId 1,
+ Job=Client1.2003-04-28_14.22.33
+28-Apr-2003 14:22 rufus-sd: Job Client1.2003-04-28_14.22.33 waiting.
+ Cannot find any appendable volumes.
+Please use the "label" command to create a new Volume for:
+ Storage: FileStorage
+ Media type: File
+ Pool: Default
+\end{verbatim}
+\normalsize
+
+The first message, indicates that no previous Full backup was done, so Bacula
+is upgrading our Incremental job to a Full backup (this is normal). The second
+message indicates that the job started with JobId 1., and the third message
+tells us that Bacula cannot find any Volumes in the Pool for writing the
+output. This is normal because we have not yet created (labeled) any Volumes.
+Bacula indicates to you all the details of the volume it needs.
+
+At this point, the job is BLOCKED waiting for a Volume. You can check this if
+you want by doing a {\bf status dir}. In order to continue, we must create a
+Volume that Bacula can write on. We do so with:
+
+\footnotesize
+\begin{verbatim}
+label
+\end{verbatim}
+\normalsize
+
+and Bacula will print:
+
+\footnotesize
+\begin{verbatim}
+The defined Storage resources are:
+ 1: File
+Item 1 selected automatically.
+Enter new Volume name:
+\end{verbatim}
+\normalsize
+
+at which point, you should enter some name beginning with a letter and
+containing only letters and numbers (period, hyphen, and underscore) are also
+permitted. For example, enter {\bf TestVolume001}, and you should get back:
+
+\footnotesize
+\begin{verbatim}
+Defined Pools:

+\normalsize
+
+If you don't see the output immediately, you can keep entering {\bf messages}
+until the job terminates, or you can enter, {\bf autodisplay on} and your
+messages will automatically be displayed as soon as they are ready.
+
+If you do an {\bf ls -l} of your {\bf /tmp} directory, you will see that you
+have the following item:

+\footnotesize
+\begin{verbatim}

+\end{verbatim}
+\normalsize
+
+This is the file Volume that you just wrote and it contains all the data of
+the job just run. If you run additional jobs, they will be appended to this
+Volume unless you specify otherwise.
+
+You might ask yourself if you have to label all the Volumes that Bacula is
+going to use. The answer for disk Volumes, like the one we used, is no. It is
+possible to have Bacula automatically label volumes. For tape Volumes, you
+will most likely have to label each of the Volumes you want to use.
+
+If you would like to stop here, you can simply enter {\bf quit} in the Console
+program, and you can stop Bacula with {\bf ./bacula stop}. To clean up, simply
+delete the file {\bf /tmp/TestVolume001}, and you should also re-initialize
+your database using:
+
+\footnotesize
+\begin{verbatim}
+./drop_bacula_tables
+./make_bacula_tables
+\end{verbatim}
+\normalsize
+
+Please note that this will erase all information about the previous jobs that

+\index[general]{Restoring Your Files }
+
+If you have run the default configuration and the save of the Bacula source

+
+\footnotesize
+\begin{verbatim}
+restore all
+\end{verbatim}
+\normalsize
+
+where you will get:
+
+\footnotesize
+\begin{verbatim}
+First you select one or more JobIds that contain files
+to be restored. You will be presented several methods
+of specifying the JobIds. Then you will be allowed to
+select which files from those JobIds are to be restored.
+
+To select the JobIds, you have the following choices:
+ 1: List last 20 Jobs run
+ 2: List Jobs where a given File is saved
+ 3: Enter list of comma separated JobIds to select
+ 4: Enter SQL list command
+ 5: Select the most recent backup for a client
+ 6: Select backup for a client before a specified time
+ 7: Enter a list of files to restore

+As you can see by starting at the top of the listing, Bacula knows what client
+you have, and since there was only one, it selected it automatically, likewise
+for the FileSet. Then Bacula produced a listing containing all the jobs that
+form the current backup, in this case, there is only one, and the Storage
+daemon was also automatically chosen. Bacula then took all the files that were
+in Job number 1 and entered them into a {\bf directory tree} (a sort of in
+memory representation of your filesystem). At this point, you can use the {\bf
+cd} and {\bf ls} ro {\bf dir} commands to walk up and down the directory tree
+and view what files will be restored. For example, if I enter {\bf cd
+/home/kern/bacula/bacula-1.30} and then enter {\bf dir} I will get a listing
+of all the files in the Bacula source directory. On your system, the path will
+be somewhat different. For more information on this, please refer to the

+\label{SecondClient}

+\section{Adding a Second Client}
+\index[general]{Client!Adding a Second }
+\index[general]{Adding a Second Client }
+
+If you have gotten the example shown above to work on your system, you may be
+ready to add a second Client (File daemon). That is you have a second machine
+that you would like backed up. The only part you need installed on the other
+machine is the binary {\bf bacula-fd} (or {\bf bacula-fd.exe} for Windows) and
+its configuration file {\bf bacula-fd.conf}. You can start with the same {\bf
+bacula-fd.conf} file that you are currently using and make one minor
+modification to it to create the conf file for your second client. Change the
+File daemon name from whatever was configured, {\bf rufus-fd} in the example
+above, but your system will have a different name. The best is to change it to
+the name of your second machine. For example:
+
+\footnotesize
+\begin{verbatim}
+...
+#
+# "Global" File daemon configuration specifications
+#
+FileDaemon { # this is me
+ Name = rufus-fd
+ FDport = 9102 # where we listen for the director
+ WorkingDirectory = /home/kern/bacula/working
+ Pid Directory = /var/run
+}
+...
+\end{verbatim}
+\normalsize
+
+would become:
+
+\footnotesize
+\begin{verbatim}
+...
+#
+# "Global" File daemon configuration specifications
+#
+FileDaemon { # this is me
+ Name = matou-fd
+ FDport = 9102 # where we listen for the director
+ WorkingDirectory = /home/kern/bacula/working
+ Pid Directory = /var/run
+}
+...
+\end{verbatim}
+\normalsize
+
+where I show just a portion of the file and have changed {\bf rufus-fd} to
+{\bf matou-fd}. The names you use are your choice. For the moment, I recommend
+you change nothing else. Later, you will want to change the password.
+
+Now you should install that change on your second machine. Then you need to
+make some additions to your Director's configuration file to define the new
+File daemon or Client. Starting from our original example which should be
+installed on your system, you should add the following lines (essentially
+copies of the existing data but with the names changed) to your Director's
+configuration file {\bf bacula-dir.conf}.
+
+\footnotesize
+\begin{verbatim}
+#
+# Define the main nightly save backup job
+# By default, this job will back up to disk in /tmp
+Job {
+ Name = "Matou"
+ Type = Backup
+ Client = matou-fd
+ FileSet = "Full Set"
+ Schedule = "WeeklyCycle"
+ Storage = File
+ Messages = Standard
+ Pool = Default
+ Write Bootstrap = "/home/kern/bacula/working/matou.bsr"
+}
+# Client (File Services) to backup
+Client {
+ Name = matou-fd
+ Address = matou
+ FDPort = 9102
+ Catalog = MyCatalog
+ Password = "xxxxx" # password for
+ File Retention = 30d # 30 days
+ Job Retention = 180d # six months
+ AutoPrune = yes # Prune expired Jobs/Files
+}
+\end{verbatim}
+\normalsize
+
+Then make sure that the Address parameter in the Storage resource is set to
+the fully qualified domain name and not to something like "localhost". The
+address specified is sent to the File daemon (client) and it must be a fully
+qualified domain name. If you pass something like "localhost" it will not
+resolve correctly and will result in a time out when the File daemon fails to
+connect to the Storage daemon.
+
+That is all that is necessary. I copied the existing resource to create a
+second Job (Matou) to backup the second client (matou-fd). It has the name
+{\bf Matou}, the Client is named {\bf matou-fd}, and the bootstrap file name
+is changed, but everything else is the same. This means that Matou will be
+backed up on the same schedule using the same set of tapes. You may want to
+change that later, but for now, let's keep it simple.
+
+The second change was to add a new Client resource that defines {\bf matou-fd}
+and has the correct address {\bf matou}, but in real life, you may need a
+fully qualified domain name or an IP address. I also kept the password the
+same (shown as xxxxx for the example).
+
+At this point, if you stop Bacula and restart it, and start the Client on the
+other machine, everything will be ready, and the prompts that you saw above
+will now include the second machine.
+
+To make this a real production installation, you will possibly want to use
+different Pool, or a different schedule. It is up to you to customize. In any
+case, you should change the password in both the Director's file and the
+Client's file for additional security.
+
+For some important tips on changing names and passwords, and a diagram of what
+names and passwords must match, please see
+\ilink{Authorization Errors}{AuthorizationErrors} in the FAQ chapter
+of this manual.
+
+\section{When The Tape Fills}
+\label{FullTape}
+\index[general]{Fills!When The Tape }
+\index[general]{When The Tape Fills }
+
+If you have scheduled your job, typically nightly, there will come a time when
+the tape fills up and {\bf Bacula} cannot continue. In this case, Bacula will
+send you a message similar to the following:
+
+\footnotesize
+\begin{verbatim}
+rufus-sd: block.c:337 === Write error errno=28: ERR=No space left
+ on device
+\end{verbatim}
+\normalsize
+
+This indicates that Bacula got a write error because the tape is full. Bacula
+will then search the Pool specified for your Job looking for an appendable
+volume. In the best of all cases, you will have properly set your Retention
+Periods and you will have all your tapes marked to be Recycled, and {\bf
+Bacula} will automatically recycle the tapes in your pool requesting and
+overwriting old Volumes. For more information on recycling, please see the
+\ilink{Recycling chapter}{RecyclingChapter} of this manual. If you
+find that your Volumes were not properly recycled (usually because of a
+configuration error), please see the
+\ilink{Manually Recycling Volumes}{manualrecycling} section of
+the Recycling chapter.
+
+If like me, you have a very large set of Volumes and you label them with the
+date the Volume was first writing, or you have not set up your Retention
+periods, Bacula will not find a tape in the pool, and it will send you a
+message similar to the following:
+
+\footnotesize
+\begin{verbatim}
+rufus-sd: Job kernsave.2002-09-19.10:50:48 waiting. Cannot find any
+ appendable volumes.
+Please use the "label" command to create a new Volume for:
+ Storage: SDT-10000
+ Media type: DDS-4
+ Pool: Default
+\end{verbatim}
+\normalsize
+
+Until you create a new Volume, this message will be repeated an hour later,
+then two hours later, and so on doubling the interval each time up to a
+maximum interval of one day.
+
+The obvious question at this point is: What do I do now?
+
+The answer is simple: first, using the Console program, close the tape drive
+using the {\bf unmount} command. If you only have a single drive, it will be
+automatically selected, otherwise, make sure you release the one specified on
+the message (in this case {\bf STD-10000}).
+
+Next, you remove the tape from the drive and insert a new blank tape. Note, on
+some older tape drives, you may need to write an end of file mark ({\bf mt \
+-f \ /dev/nst0 \ weof}) to prevent the drive from running away when Bacula
+attempts to read the label.
+
+Finally, you use the {\bf label} command in the Console to write a label to
+the new Volume. The {\bf label} command will contact the Storage daemon to
+write the software label, if it is successful, it will add the new Volume to
+the Pool, then issue a {\bf mount} command to the Storage daemon. See the
+previous sections of this chapter for more details on labeling tapes.
+
+The result is that Bacula will continue the previous Job writing the backup to
+the new Volume.
+
+If you have a Pool of volumes and Bacula is cycling through them, instead of
+the above message "Cannot find any appendable volumes.", Bacula may ask you
+to mount a specific volume. In that case, you should attempt to do just that.
+If you do not have the volume any more (for any of a number of reasons), you
+can simply mount another volume from the same Pool, providing it is
+appendable, and Bacula will use it. You can use the {\bf list volumes} command
+in the console program to determine which volumes are appendable and which are
+not.
+
+If like me, you have your Volume retention periods set correctly, but you have
+no more free Volumes, you can relabel and reuse a Volume as follows:
+
+\begin{itemize}
+\item Do a {\bf list volumes} in the Console and select the oldest Volume for
+ relabeling.
+\item If you have setup your Retention periods correctly, the Volume should
+ have VolStatus {\bf Purged}.
+\item If the VolStatus is not set to Purged, you will need to purge the
+ database of Jobs that are written on that Volume. Do so by using the command
+ {\bf purge jobs volume} in the Console. If you have multiple Pools, you will
+be prompted for the Pool then enter the VolumeName (or MediaId) when
+requested.
+\item Then simply use the {\bf relabel} command to relabel the Volume.
+ \end{itemize}
+
+To manually relabel the Volume use the following additional steps:
+
+\begin{itemize}
+\item To delete the Volume from the catalog use the {\bf delete volume}
+ command in the Console and select the VolumeName (or MediaId) to be deleted.
+
+\item Use the {\bf unmount} command in the Console to unmount the old tape.
+\item Physically relabel the old Volume that you deleted so that it can be
+ reused.
+\item Insert the old Volume in the tape drive.
+\item From a command line do: {\bf mt \ -f \ /dev/st0 \ rewind} and {\bf mt \
+ -f \ /dev/st0 \ weof}, where you need to use the proper tape drive name for
+ your system in place of {\bf /dev/st0}.
+\item Use the {\bf label} command in the Console to write a new Bacula label
+ on your tape.
+\item Use the {\bf mount} command in the Console if it is not automatically
+ done, so that Bacula starts using your newly labeled tape.
+ \end{itemize}
+

+\index[general]{Commands!Other Useful Console }
+\index[general]{Other Useful Console Commands }
+
+\begin{description}
+
+\item [status dir]
+ \index[console]{status dir }
+ Print a status of all running jobs and jobs scheduled in the next 24 hours.
+
+\item [status]
+ \index[console]{status }
+ The console program will prompt you to select a daemon type, then will
+request the daemon's status.
+
+\item [status jobid=nn]
+ \index[console]{status jobid }
+ Print a status of JobId nn if it is running. The Storage daemon is contacted
+and requested to print a current status of the job as well.
+
+\item [list pools]
+ \index[console]{list pools }
+ List the pools defined in the Catalog (normally only Default is used).
+
+\item [list media]
+ \index[console]{list media }
+ Lists all the media defined in the Catalog.
+
+\item [list jobs]
+ \index[console]{list jobs }
+ Lists all jobs in the Catalog that have run.

+
+
+\item [mount storage=storage-name]
+ \index[sd]{mount storage }
+ Causes the drive associated with the storage device to be mounted again. When
+Bacula reaches the end of a volume and requests you to mount a new volume,
+you must issue this command after you have placed the new volume in the

+or writing the new volume.
+
+\item [quit]
+ \index[sd]{quit }
+ Exit or quit the console program.
+\end{description}
+
+Most of the commands given above, with the exception of {\bf list}, will
+prompt you for the necessary arguments if you simply enter the command name.
+
+\section{Debug Daemon Output}
+\index[general]{Debug Daemon Output }
+\index[general]{Output!Debug Daemon }
+
+If you want debug output from the daemons as they are running, start the
+daemons from the install directory as follows:
+
+\footnotesize
+\begin{verbatim}
+./bacula start -d100
+\end{verbatim}
+\normalsize
+
+This can be particularly helpful if your daemons do not start correctly,
+because direct daemon output to the console is normally directed to the
+NULL device, but with the debug level greater than zero, the output
+will be sent to the starting terminal.
+
+To stop the three daemons, enter the following from the install directory:
+
+\footnotesize
+\begin{verbatim}
+./bacula stop
+\end{verbatim}
+\normalsize
+
+The execution of {\bf bacula stop} may complain about pids not found. This is
+OK, especially if one of the daemons has died, which is very rare.
+
+To do a full system save, each File daemon must be running as root so that it
+will have permission to access all the files. None of the other daemons
+require root privileges. However, the Storage daemon must be able to open the
+tape drives. On many systems, only root can access the tape drives. Either run
+the Storage daemon as root, or change the permissions on the tape devices to
+permit non-root access. MySQL and PostgreSQL can be installed and run with any
+userid; root privilege is not necessary.
+
+\section{Patience When Starting Daemons or Mounting Blank Tapes}
+
+When you start the Bacula daemons, the Storage daemon attempts to open all
+defined storage devices and verify the currently mounted Volume (if
+configured). Until all the storage devices are verified, the Storage daemon
+will not accept connections from the Console program. If a tape was previously
+used, it will be rewound, and on some devices this can take several minutes.
+As a consequence, you may need to have a bit of patience when first contacting
+the Storage daemon after starting the daemons. If you can see your tape drive,
+once the lights stop flashing, the drive will be ready to be used.
+
+The same considerations apply if you have just mounted a blank tape in a drive
+such as an HP DLT. It can take a minute or two before the drive properly
+recognizes that the tape is blank. If you attempt to {\bf mount} the tape with
+the Console program during this recognition period, it is quite possible that
+you will hang your SCSI driver (at least on my Red Hat Linux system). As a
+consequence, you are again urged to have patience when inserting blank tapes.
+Let the device settle down before attempting to access it.
+
+\section{Difficulties Connecting from the FD to the SD}
+\index[general]{Difficulties Connecting from the FD to the SD}
+\index[general]{SD!Difficulties Connecting from the FD to the SD}
+
+If you are having difficulties getting one or more of your File daemons to
+connect to the Storage daemon, it is most likely because you have not used a
+fully qualified domain name on the {\bf Address} directive in the
+Director's Storage resource. That is the resolver on the File daemon's machine
+(not on the Director's) must be able to resolve the name you supply into an IP
+address. An example of an address that is guaranteed not to work: {\bf
+localhost}. An example that may work: {\bf megalon}. An example that is more
+likely to work: {\bf magalon.mydomain.com}. On Win32 if you don't have a good
+resolver (often true on older Win98 systems), you might try using an IP
+address in place of a name.
+
+If your address is correct, then make sure that no other program is using the
+port 9103 on the Storage daemon's machine. The Bacula port numbers are
+authorized by IANA, and should not be used by other programs, but apparently
+some HP printers do use these port numbers. A {\bf netstat -a} on the Storage
+daemon's machine can determine who is using the 9103 port (used for FD to SD
+communications in Bacula).
+
+\section{Daemon Command Line Options}
+\index[general]{Daemon Command Line Options }
+\index[general]{Options!Daemon Command Line }
+
+Each of the three daemons (Director, File, Storage) accepts a small set of
+options on the command line. In general, each of the daemons as well as the
+Console program accepts the following options:
+
+\begin{description}
+
+\item [-c \lt{}file\gt{}]
+ \index[sd]{-c \lt{}file\gt{} }
+ Define the file to use as a configuration file. The default is the daemon
+ name followed by {\bf .conf} i.e. {\bf bacula-dir.conf} for the Director,
+ {\bf bacula-fd.conf} for the File daemon, and {\bf bacula-sd} for the Storage
+ daemon.
+
+\item [-d nn]
+ \index[sd]{-d nn }
+ Set the debug level to {\bf nn}. Higher levels of debug cause more
+ information to be displayed on STDOUT concerning what the daemon is doing.
+
+\item [-f]
+ Run the daemon in the foreground. This option is needed to run the daemon
+ under the debugger.
+
+\item [-g <group>]
+ Run the daemon under this group. This must be a group name, not a GID.
+
+\item [-s]
+ Do not trap signals. This option is needed to run the daemon under the
+ debugger.
+
+\item [-t]
+ Read the configuration file and print any error messages, then immediately
+ exit. Useful for syntax testing of new configuration files.
+
+\item [-u <user>]
+ Run the daemon as this user. This must be a user name, not a UID.
+
+\item [-v]
+ Be more verbose or more complete in printing error and informational
+ messages. Recommended.
+
+\item [-?]
+ Print the version and list of options.
+
+\end{description}
+

+\section{Creating a Pool}
+\label{Pool}
+\index[general]{Pool!Creating a }
+\index[general]{Creating a Pool }
+
+Creating the Pool is automatically done when {\bf Bacula} starts, so if you
+understand Pools, you can skip to the next section.
+
+When you run a job, one of the things that Bacula must know is what Volumes to
+use to backup the FileSet. Instead of specifying a Volume (tape) directly, you
+specify which Pool of Volumes you want Bacula to consult when it wants a tape
+for writing backups. Bacula will select the first available Volume from the
+Pool that is appropriate for the Storage device you have specified for the Job
+being run. When a volume has filled up with data, {\bf Bacula} will change its
+VolStatus from {\bf Append} to {\bf Full}, and then {\bf Bacula} will use the
+next volume and so on. If no appendable Volume exists in the Pool, the
+Director will attempt to recycle an old Volume, if there are still no
+appendable Volumes available, {\bf Bacula} will send a message requesting the
+operator to create an appropriate Volume.
+
+{\bf Bacula} keeps track of the Pool name, the volumes contained in the Pool,
+and a number of attributes of each of those Volumes.
+
+When Bacula starts, it ensures that all Pool resource definitions have been
+recorded in the catalog. You can verify this by entering:
+
+\footnotesize
+\begin{verbatim}
+list pools
+\end{verbatim}
+\normalsize
+
+to the console program, which should print something like the following:
+
+\footnotesize
+\begin{verbatim}
+*list pools
+Using default Catalog name=MySQL DB=bacula
++--------+---------+---------+---------+----------+-------------+
+| PoolId | Name | NumVols | MaxVols | PoolType | LabelFormat |
++--------+---------+---------+---------+----------+-------------+
+| 1 | Default | 3 | 0 | Backup | * |
+| 2 | File | 12 | 12 | Backup | File |
++--------+---------+---------+---------+----------+-------------+
+*
+\end{verbatim}
+\normalsize
+
+If you attempt to create the same Pool name a second time, {\bf Bacula} will
+print:
+
+\footnotesize
+\begin{verbatim}
+Error: Pool Default already exists.
+Once created, you may use the {\bf update} command to
+modify many of the values in the Pool record.
+\end{verbatim}
+\normalsize
+
+\label{Labeling}
+
+\section{Labeling Your Volumes}
+\index[general]{Volumes!Labeling Your }
+\index[general]{Labeling Your Volumes }
+
+Bacula requires that each Volume contains a software label. There are several
+strategies for labeling volumes. The one I use is to label them as they are
+needed by {\bf Bacula} using the console program. That is when Bacula needs a
+new Volume, and it does not find one in the catalog, it will send me an email
+message requesting that I add Volumes to the Pool. I then use the {\bf label}
+command in the Console program to label a new Volume and to define it in the
+Pool database, after which Bacula will begin writing on the new Volume.
+Alternatively, I can use the Console {\bf relabel} command to relabel a Volume
+that is no longer used providing it has VolStatus {\bf Purged}.
+
+Another strategy is to label a set of volumes at the start, then use them as
+{\bf Bacula} requests them. This is most often done if you are cycling through
+a set of tapes, for example using an autochanger. For more details on
+recycling, please see the
+\ilink{Automatic Volume Recycling}{RecyclingChapter} chapter of
+this manual.
+
+If you run a Bacula job, and you have no labeled tapes in the Pool, Bacula
+will inform you, and you can create them "on-the-fly" so to speak. In my
+case, I label my tapes with the date, for example: {\bf DLT-18April02}. See
+below for the details of using the {\bf label} command.
+
+\section{Labeling Volumes with the Console Program}
+\index[general]{Labeling Volumes with the Console Program }
+\index[general]{Program!Labeling Volumes with the Console }
+
+Labeling volumes is normally done by using the console program.
+
+\begin{enumerate}
+\item ./bconsole
+\item label
+ \end{enumerate}
+
+If Bacula complains that you cannot label the tape because it is already
+labeled, simply {\bf unmount} the tape using the {\bf unmount} command in the
+console, then physically mount a blank tape and re-issue the {\bf label}
+command.
+
+Since the physical storage media is different for each device, the {\bf label}
+command will provide you with a list of the defined Storage resources such as
+the following:
+
+\footnotesize
+\begin{verbatim}
+The defined Storage resources are:
+ 1: File
+ 2: 8mmDrive
+ 3: DLTDrive
+ 4: SDT-10000
+Select Storage resource (1-4):
+\end{verbatim}
+\normalsize
+
+At this point, you should have a blank tape in the drive corresponding to the
+Storage resource that you select.
+
+It will then ask you for the Volume name.
+
+\footnotesize
+\begin{verbatim}
+Enter new Volume name:
+\end{verbatim}
+\normalsize
+
+If Bacula complains:
+
+\footnotesize
+\begin{verbatim}
+Media record for Volume xxxx already exists.
+\end{verbatim}
+\normalsize
+
+It means that the volume name {\bf xxxx} that you entered already exists in
+the Media database. You can list all the defined Media (Volumes) with the {\bf
+list media} command. Note, the LastWritten column has been truncated for
+proper printing.
+

+\end{verbatim}
+\normalsize
+
+Once Bacula has verified that the volume does not already exist, it will
+prompt you for the name of the Pool in which the Volume (tape) is to be
+created. If there is only one Pool (Default), it will be automatically
+selected.
+
+If the tape is successfully labeled, a Volume record will also be created in
+the Pool. That is the Volume name and all its other attributes will appear
+when you list the Pool. In addition, that Volume will be available for backup
+if the MediaType matches what is requested by the Storage daemon.
+
+When you labeled the tape, you answered very few questions about it --
+principally the Volume name, and perhaps the Slot. However, a Volume record in
+the catalog database (internally known as a Media record) contains quite a few
+attributes. Most of these attributes will be filled in from the default values
+that were defined in the Pool (i.e. the Pool holds most of the default
+attributes used when creating a Volume).
+
+It is also possible to add media to the pool without physically labeling the
+Volumes. This can be done with the {\bf add} command. For more information,
+please see the
+\ilink{Console Chapter}{_ConsoleChapter} of this manual.

+\chapter{Variable Expansion}
+\label{VarsChapter}
+\index[general]{Variable Expansion }
+\index[general]{Expansion!Variable }
+
+% TODO: does the following mean that this should not be in book?
+
+Please note that as of version 1.37, the Variable Expansion
+is deprecated and replaced by Python scripting (not yet
+documented).
+
+Variable expansion is somewhat similar to Unix shell variable expansion.
+Currently (version 1.31), it is used only in format labels, but in the future,
+it will most likely be used in more places.
+
+\section{General Functionality}
+\index[general]{Functionality!General }
+\index[general]{General Functionality }
+
+This is basically a string expansion capability that permits referencing
+variables, indexing arrays, conditional replacement of variables, case
+conversion, substring selection, regular expression matching and replacement,
+character class replacement, padding strings, repeated expansion in a user
+controlled loop, support of arithmetic expressions in the loop start, step and
+end conditions, and recursive expansion.
+
+When using variable expansion characters in a Volume Label Format record, the
+format should always be enclosed in double quotes ({\bf "}).
+
+For example, {\bf \$\{HOME\}} will be replaced by your home directory as
+defined in the environment. If you have defined the variable {\bf xxx} to be
+{\bf Test}, then the reference {\bf \$\{xxx:p/7/Y/r\}} will right pad the
+contents of {\bf xxx} to a length of seven characters filling with the
+character {\bf Y} giving {\bf YYYTest}.
+
+\section{Bacula Variables}
+\index[general]{Bacula Variables }
+\index[general]{Variables!Bacula }
+
+Within Bacula, there are three main classes of variables with some minor
+variations within the classes. The classes are:
+
+\begin{description}
+
+\item [Counters]
+ \index[dir]{Counters }
+ Counters are defined by the {\bf Counter} resources in the Director's conf
+file. The counter can either be a temporary counter that lasts for the
+duration of Bacula's execution, or it can be a variable that is stored in
+the catalog, and thus retains its value from one Bacula execution to another.
+Counter variables may be incremented by postfixing a plus sign ({\bf +} after
+the variable name).
+
+\item [Internal Variables]
+ \index[dir]{Internal Variables }
+ Internal variables are read-only, and may be related to the current job (i.e.
+Job name), or maybe special variables such as the date and time. The
+following variables are available:
+
+\begin{itemize}
+\item [Year] -- the full year
+\item [Month] -- the current month 1-12
+\item [Day] -- the day of the month 1-31
+\item [Hour] -- the hour 0-24
+\item [Minute] -- the current minute 0-59
+\item [Second] -- the current second 0-59
+\item [WeekDay] -- the current day of the week 0-6 with 0 being Sunday
+\item [Job] -- the job name
+\item [Dir] -- the Director's name
+\item [Level] -- the Job Level
+\item [Type] -- the Job type
+\item [JobId] -- the JobId
+\item [JobName] -- the unique job name composed of Job and date
+\item [Storage] -- the Storage daemon's name
+\item [Client] -- the Client's name
+\item [NumVols] -- the current number of Volumes in the Pool
+\item [Pool] -- the Pool name
+\item [Catalog] -- the Catalog name
+\item [MediaType] -- the Media Type
+ \end{itemize}
+
+\item [Environment Variables]
+ \index[dir]{Environment Variables }
+ Environment variables are read-only, and must be defined in the environment
+prior to executing Bacula. Environment variables may be either scalar or an
+array, where the elements of the array are referenced by subscripting the
+variable name (e.g. {\bf \$\{Months[3]\}}). Environment variable arrays are
+defined by separating the elements with a vertical bar ({\bf |}), thus {\bf
+set Months="Jan|Feb|Mar|Apr|..."} defines an environment variable named
+{\bf Month} that will be treated as an array, and the reference {\bf
+\$\{Months[3]\}} will yield {\bf Mar}. The elements of the array can have
+differing lengths.
+\end{description}
+
+\section{Full Syntax}
+\index[general]{Syntax!Full }
+\index[general]{Full Syntax }
+
+Since the syntax is quite extensive, below, you will find the pseudo BNF. The
+special characters have the following meaning:
+
+\footnotesize
+\begin{verbatim}
+ ::= definition
+ ( ) grouping if the parens are not quoted
+ | separates alternatives
+ '/' literal / (or any other character)
+ CAPS a character or character sequence
+ * preceding item can be repeated zero or more times
+ ? preceding item can appear zero or one time
+ + preceding item must appear one or more times
+\end{verbatim}
+\normalsize
+
+And the pseudo BNF describing the syntax is:
+
+\footnotesize
+\begin{verbatim}
+ input ::= ( TEXT
+ | variable
+ | INDEX_OPEN input INDEX_CLOSE (loop_limits)?
+ )*
+ variable ::= DELIM_INIT (name|expression)

+ NAME_CHARS ::= 'a'|...|'z'|'A'|...|'Z'|'0'|...|'9'
+\end{verbatim}
+\normalsize
+
+\section{Semantics}
+\index[general]{Semantics }
+
+The items listed in {\bf command} above, which always follow a colon ({\bf :})
+have the following meanings:
+
+\footnotesize
+\begin{verbatim}
+ - perform substitution if variable is empty
+ + perform substitution if variable is not empty
+ o cut out substring of the variable value
+ # length of the variable value
+ * substitute empty string if the variable value is not empty,
+ otherwise substitute the trailing parameter
+ s regular expression search and replace. The trailing
+ options are: m = multiline, i = case insensitive,
+ g = global, t = plain text (no regexp)
+ y transpose characters from class A to class B
+ p pad variable to l = left, r = right or c = center,
+ with second value.
+ % special function call (none implemented)
+ l lower case the variable value
+ u upper case the variable value
+\end{verbatim}
+\normalsize
+
+The {\bf loop\_limits} are start, step, and end values.
+
+A counter variable name followed immediately by a plus ({\bf +}) will cause
+the counter to be incremented by one.

+\index[general]{Security!Using Bacula to Improve Computer }
+\index[general]{Using Bacula to Improve Computer Security }
+
+% TODO: only those two digest algorithms?
+% TODO: can it use multiple at a time? (record and use both SHA1 and MD5?)
+Since Bacula maintains a catalog of files, their attributes, and either SHA1
+or MD5 signatures, it can be an ideal tool for improving computer security.
+This is done by making a snapshot of your system files with a {\bf Verify} Job
+and then checking the current state of your system against the snapshot, on a
+regular basis (e.g. nightly).
+
+The first step is to set up a {\bf Verify} Job and to run it with:
+
+\footnotesize
+\begin{verbatim}
+Level = InitCatalog
+\end{verbatim}
+\normalsize
+
+The {\bf InitCatalog} level tells {\bf Bacula} simply to get the information on
+the specified files and to put it into the catalog. That is your database is
+initialized and no comparison is done. The {\bf InitCatalog} is normally run
+one time manually.
+
+Thereafter, you will run a Verify Job on a daily (or whatever) basis with:
+
+\footnotesize
+\begin{verbatim}
+Level = Catalog
+\end{verbatim}
+\normalsize
+
+The {\bf Level = Catalog} level tells Bacula to compare the current state of
+the files on the Client to the last {\bf InitCatalog} that is stored in the
+catalog and to report any differences. See the example below for the format of
+the output.
+
+You decide what files you want to form your "snapshot" by specifying them in
+a {\bf FileSet} resource, and normally, they will be system files that do not
+change, or that only certain features change.
+
+Then you decide what attributes of each file you want compared by specifying
+comparison options on the {\bf Include} statements that you use in the {\bf
+FileSet} resource of your {\bf Catalog} Jobs.
+
+\section{The Details}
+\index[general]{Details }
+
+In the discussion that follows, we will make reference to the Verify
+Configuration Example that is included below in the {\bf A Verify
+Configuration Example} section. You might want to look it over now to get an
+idea of what it does.
+
+The main elements consist of adding a schedule, which will normally be run
+daily, or perhaps more often. This is provided by the {\bf VerifyCycle}
+Schedule, which runs at 5:05 in the morning every day.
+
+Then you must define a Job, much as is done below. We recommend that the Job
+name contain the name of your machine as well as the word {\bf Verify} or {\bf
+Check}. In our example, we named it {\bf MatouVerify}. This will permit you to
+easily identify your job when running it from the Console.
+
+You will notice that most records of the Job are quite standard, but that the
+{\bf FileSet} resource contains {\bf verify=pins1} option in addition to the
+standard {\bf signature=SHA1} option. If you don't want SHA1 signature
+comparison, and we cannot imagine why not, you can drop the {\bf
+signature=SHA1} and none will be computed nor stored in the catalog. Or
+alternatively, you can use {\bf verify=pins5} and {\bf signature=MD5}, which
+will use the MD5 hash algorithm. The MD5 hash computes faster than SHA1, but
+is cryptographically less secure.
+
+The {\bf verify=pins1} is ignored during the {\bf InitCatalog} Job, but is
+used during the subsequent {\bf Catalog} Jobs to specify what attributes of
+the files should be compared to those found in the catalog. {\bf pins1} is a
+reasonable set to begin with, but you may want to look at the details of these
+and other options. They can be found in the
+\ilink{FileSet Resource}{FileSetResource} section of this manual.
+Briefly, however, the {\bf p} of the {\bf pins1} tells Verify to compare the
+permissions bits, the {\bf i} is to compare inodes, the {\bf n} causes
+comparison of the number of links, the {\bf s} compares the file size, and the
+{\bf 1} compares the SHA1 checksums (this requires the {\bf signature=SHA1}
+option to have been set also).
+
+You must also specify the {\bf Client} and the {\bf Catalog} resources for
+your Verify job, but you probably already have them created for your client
+and do not need to recreate them, they are included in the example below for
+completeness.
+
+As mentioned above, you will need to have a {\bf FileSet} resource for the
+Verify job, which will have the additional {\bf verify=pins1} option. You will
+want to take some care in defining the list of files to be included in your
+{\bf FileSet}. Basically, you will want to include all system (or other) files
+that should not change on your system. If you select files, such as log files
+or mail files, which are constantly changing, your automatic Verify job will
+be constantly finding differences. The objective in forming the FileSet is to
+choose all unchanging important system files. Then if any of those files has
+changed, you will be notified, and you can determine if it changed because you
+loaded a new package, or because someone has broken into your computer and
+modified your files. The example below shows a list of files that I use on my
+Red Hat 7.3 system. Since I didn't spend a lot of time working on it, it
+probably is missing a few important files (if you find one, please send it to
+me). On the other hand, as long as I don't load any new packages, none of
+these files change during normal operation of the system.
+
+\section{Running the Verify}
+\index[general]{Running the Verify }
+\index[general]{Verify!Running the }
+
+The first thing you will want to do is to run an {\bf InitCatalog} level
+Verify Job. This will initialize the catalog to contain the file information
+that will later be used as a basis for comparisons with the actual file
+system, thus allowing you to detect any changes (and possible intrusions into
+your system).
+
+The easiest way to run the {\bf InitCatalog} is manually with the console
+program by simply entering {\bf run}. You will be presented with a list of
+Jobs that can be run, and you will choose the one that corresponds to your
+Verify Job, {\bf MatouVerify} in this example.
+
+\footnotesize
+\begin{verbatim}
+The defined Job resources are:
+ 1: MatouVerify
+ 2: kernsrestore
+ 3: Filetest
+ 4: kernsave
+Select Job resource (1-4): 1
+\end{verbatim}
+\normalsize
+
+Next, the console program will show you the basic parameters of the Job and
+ask you:
+
+\footnotesize
+\begin{verbatim}
+Run Verify job
+JobName: MatouVerify
+FileSet: Verify Set
+Level: Catalog
+Client: MatouVerify
+Storage: DLTDrive
+OK to run? (yes/mod/no): mod
+\end{verbatim}
+\normalsize
+
+Here, you want to respond {\bf mod} to modify the parameters because the Level
+is by default set to {\bf Catalog} and we want to run an {\bf InitCatalog}
+Job. After responding {\bf mod}, the console will ask:
+
+\footnotesize
+\begin{verbatim}

+\chapter{The Windows Version of Bacula}
+\label{Win32Chapter}
+\index[general]{Windows Version of Bacula}
+
+At the current time only the File daemon or Client program has
+been thouroughly tested on Windows and is suitable for a
+production environment. As a consequence, when we
+speak of the Windows version of Bacula below, we are referring to
+the File daemon (client) only.
+
+As of Bacula version 1.39.20 or greater, the installer is capable
+of installing not just the Client program, but also the Director
+and the Storage daemon and all the other programs that were
+previously available only on Unix systems. These additional
+programs, notably the Director and Storage daemon, have been partially
+tested, are reported to have some bugs, and still need to be documented.
+They are not yet supported, and we cannot currently accept or fix
+bug reports on them. Consequently, please test them carefully before putting
+them into a critical production environment.
+
+The Windows version of the Bacula File daemon has been tested on Win98, WinMe,
+WinNT, WinXP, Win2000, and Windows 2003 systems. We have coded to support
+Win95, but no longer have a system for testing. The Windows version of
+Bacula is a native Win32 port, but there are very few source code changes
+to the Unix code, which means that the Windows version is for the most part
+running code that has long proved stable on Unix systems. When running, it
+is perfectly integrated with Windows and displays its icon in the system
+icon tray, and provides a system tray menu to obtain additional information
+on how Bacula is running (status and events dialog boxes). If so desired,
+it can also be stopped by using the system tray menu, though this should
+normally never be necessary.
+
+Once installed Bacula normally runs as a system service. This means that it is
+immediately started by the operating system when the system is booted, and
+runs in the background even if there is no user logged into the system.
+
+\section{Win32 Installation}
+\label{installation}
+\index[general]{Installation}
+\index[general]{Win32!Installation}
+
+Normally, you will install the Windows version of Bacula from the binaries.
+This install is standard Windows .exe that runs an install wizard using the
+NSIS Free Software installer, so if you have already installed Windows
+software, it should be very familiar to you.
+
+If you have a previous version Bacula (1.39.20 or lower)
+installed, you should stop the service, uninstall it, and remove
+the Bacula installation directory possibly saving your
+bacula-fd.conf, bconsole.conf, and bwx-console.conf files
+for use with the new version you will install. The Uninstall
+program is normally found in {\bf c:\textbackslash{}bacula\textbackslash{}Uninstall.exe}.
+We also recommend that you completely remove the directory
+{\bf c:\textbackslash{}bacula}, because the current installer
+uses a different directory structure (see below).
+
+Providing you do not already have Bacula installed,
+the new installer (1.39.22 and later) installs the binaries and dlls in
+c:\textbackslash{}Program Files\textbackslash{}Bacula\textbackslash{}bin
+and the configuration files
+in c:\textbackslash{}Documents and Settings\textbackslash{}All Users\textbackslash{}Application Data\textbackslash{}Bacula
+In addition, the {\bf Start\-\gt{}All Programs\-\gt{}Bacula} menu item
+will be created during the installation, and on that menu, you
+will find items for editing the configuration files, displaying
+the document, and starting bwx-console or bconsole.
+
+
+Finally, proceed with the installation.
+
+\begin{itemize}
+\item You must be logged in as Administrator to the local machine
+to do a correct installation, if not, please do so before continuing.
+Some users have attempted to install logged in as a domain administrator
+account and experienced permissions problems attempting to run
+Bacula, so we don't recommend that option.
+
+\item Simply double click on the {\bf winbacula-1.xx.0.exe} NSIS install
+ icon. The actual name of the icon will vary from one release version to
+ another.
+
+\includegraphics{\idir win32-nsis.eps} winbacula-1.xx.0.exe
+
+\item Once launched, the installer wizard will ask you if you want to install
+ Bacula.
+
+\addcontentsline{lof}{figure}{Win32 Client Setup Wizard}
+\includegraphics{\idir win32-welcome.eps}
+
+\item Next you will be asked to select the installation type.
+
+\addcontentsline{lof}{figure}{Win32 Installation Type}
+\includegraphics{\idir win32-installation-type.eps}
+
+
+\item If you proceed, you will be asked to select the components to be
+ installed. You may install the Bacula program (Bacula File Service) and or
+ the documentation. Both will be installed in sub-directories of the install
+ location that you choose later. The components dialog looks like the
+ following:
+
+\addcontentsline{lof}{figure}{Win32 Component Selection Dialog}
+\includegraphics{\idir win32-pkg.eps}
+\index[general]{Upgrading}
+
+\item If you are installing for the first time, you will be asked to
+ enter some very basic information about your configuration. If
+ you are not sure what to enter, or have previously saved configuration
+ files, you can put anything you want into the fields, then either
+ replace the configuration files later with the ones saved, or edit
+ the file.
+
+ If you are upgrading an existing installation, the following will
+ not be displayed.
+
+
+\addcontentsline{lof}{figure}{Win32 Configure}
+\includegraphics{\idir win32-config.eps}
+
+\item While the various files are being loaded, you will see the following
+ dialog:
+
+ \addcontentsline{lof}{figure}{Win32 Install Progress}
+ \includegraphics{\idir win32-installing.eps}
+
+
+\item Finally, the finish dialog will appear:
+
+ \addcontentsline{lof}{figure}{Win32 Client Setup Completed}
+ \includegraphics{\idir win32-finish.eps}
+
+\
+\end{itemize}
+
+That should complete the installation process. When the Bacula File Server is
+ready to serve files, an icon \includegraphics{\idir idle.eps} representing a
+cassette (or tape) will appear in the system tray
+\includegraphics{\idir tray-icon.eps}; right click on it and a menu will appear.\\
+\includegraphics{\idir menu.eps}\\
+The {\bf Events} item is currently unimplemented, by selecting the {\bf
+Status} item, you can verify whether any jobs are running or not.
+
+When the Bacula File Server begins saving files, the color of the holes in the
+cassette icon will change from white to green \includegraphics{\idir running.eps},
+and if there is an error, the holes in the cassette icon will change to red
+\includegraphics{\idir error.eps}.
+
+If you are using remote desktop connections between your Windows boxes, be
+warned that that tray icon does not always appear. It will always be visible
+when you log into the console, but the remote desktop may not display it.
+
+\section{Post Win32 Installation}
+\index[general]{Post Win32 Installation}
+\index[general]{Win32!Post Installation}
+
+After installing Bacula and before running it, you should check the contents
+of the configuration files to ensure that they correspond to your
+installation. You can get to them by using:
+the {\bf Start\-\gt{}All Programs\-\gt{}Bacula} menu item.
+
+Finally, but pulling up the Task Manager (ctl-alt-del), verify that Bacula
+is running as a process (not an Application) with User Name SYSTEM. If this is
+not the case, you probably have not installed Bacula while running as
+Administrator, and hence it will be unlikely that Bacula can access
+all the system files.
+
+\section{Uninstalling Bacula on Win32}
+\index[general]{Win32!Uninstalling Bacula}
+\index[general]{Uninstalling Bacula on Win32}
+
+Once Bacula has been installed, it can be uninstalled using the standard
+Windows Add/Remove Programs dialog found on the Control panel.
+
+\section{Dealing with Win32 Problems}
+\label{problems}
+\index[general]{Win32!Dealing with Problems}
+\index[general]{Dealing with Win32 Problems}
+
+Sometimes Win32 machines the File daemon may have very slow
+backup transfer rates compared to other machines. To you might
+try setting the Maximum Network Buffer Size to 32,768 in both the
+File daemon and in the Storage daemon. The default size is larger,
+and apparently some Windows ethernet controllers do not deal with
+a larger network buffer size.
+
+Many Windows ethernet drivers have a tendency to either run slowly
+due to old broken firmware, or because they are running in half-duplex
+mode. Please check with the ethernet card manufacturer for the latest
+firmware and use whatever techniques are necessary to ensure that the
+card is running in duplex.
+
+If you are not using the portable option, and you have VSS
+(Volume Shadow Copy) enabled in the Director, and you experience
+problems with Bacula not being able to open files, it is most
+likely that you are running an antivirus program that blocks
+Bacula from doing certain operations. In this case, disable the
+antivirus program and try another backup. If it succeeds, either
+get a different (better) antivirus program or use something like
+RunClientJobBefore/After to turn off the antivirus program while
+the backup is running.
+
+If turning off anti-virus software does not resolve your VSS
+problems, you might have to turn on VSS debugging. The following
+link describes how to do this:
+\elink{http://support.microsoft.com/kb/887013/en-us}{\url{http://support.microsoft.com/kb/887013/en-us}}.
+
+In Microsoft Windows Small Business Server 2003 the VSS Writer for Exchange
+is turned off by default. To turn it on, please see the following link:
+\elink{http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q838183}{\url{
+http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q838183}}
+
+
+The most likely source of problems is authentication when the Director
+attempts to connect to the File daemon that you installed. This can occur if
+the names and the passwords defined in the File daemon's configuration file
+{\bf bacula-fd.conf} file on
+the Windows machine do not match with the names and the passwords in the
+Director's configuration file {\bf bacula-dir.conf} located on your Unix/Linux
+server.
+
+More specifically, the password found in the {\bf Client} resource in the
+Director's configuration file must be the same as the password in the {\bf
+Director} resource of the File daemon's configuration file. In addition, the
+name of the {\bf Director} resource in the File daemon's configuration file
+must be the same as the name in the {\bf Director} resource of the Director's
+configuration file.
+
+It is a bit hard to explain in words, but if you understand that a Director
+normally has multiple Clients and a Client (or File daemon) may permit access
+by multiple Directors, you can see that the names and the passwords on both
+sides must match for proper authentication.
+
+One user had serious problems with the configuration file until he realized
+that the Unix end of line conventions were used and Bacula wanted them in
+Windows format. This has not been confirmed though, and Bacula version 2.0.0
+and above should now accept all end of line conventions (Win32,
+Unix, Mac).
+
+Running Unix like programs on Windows machines is a bit frustrating because
+the Windows command line shell (DOS Window) is rather primitive. As a
+consequence, it is not generally possible to see the debug information and
+certain error messages that Bacula prints. With a bit of work, however, it is
+possible. When everything else fails and you want to {\bf see} what is going
+on, try the following:
+
+\footnotesize
+\begin{verbatim}
+ Start a DOS shell Window.
+ c:\Program Files\bacula\bin\bacula-fd -t >out
+ type out
+\end{verbatim}
+\normalsize
+
+The precise path to bacula-fd depends on where it is installed. The
+example above is the default used in 1.39.22 and later.
+The {\bf -t} option will cause Bacula to read the configuration file, print
+any error messages and then exit. the {\bf \gt{}} redirects the output to the
+file named {\bf out}, which you can list with the {\bf type} command.
+
+If something is going wrong later, or you want to run {\bf Bacula} with a
+debug option, you might try starting it as:
+
+\footnotesize
+\begin{verbatim}
+ c:\Program Files\bacula\bin\bacula-fd -d 100 >out
+\end{verbatim}
+\normalsize
+
+In this case, Bacula will run until you explicitly stop it, which will give
+you a chance to connect to it from your Unix/Linux server. In later versions
+of Bacula (1.34 on, I think), when you start the File daemon in debug mode it
+can write the output to a trace file {\bf bacula.trace} in the current
+directory. To enable this, before running a job, use the console, and enter:
+
+\footnotesize
+\begin{verbatim}
+ trace on
+\end{verbatim}
+\normalsize
+
+then run the job, and once you have terminated the File daemon, you will find
+the debug output in the {\bf bacula.trace} file, which will probably be
+located in the same directory as bacula-fd.exe.
+
+In addition, you should look in the System Applications log on the Control
+Panel to find any Windows errors that Bacula got during the startup process.
+
+Finally, due to the above problems, when you turn on debugging, and specify
+trace=1 on a setdebug command in the Console, Bacula will write the debug
+information to the file {\bf bacula.trace} in the directory from which Bacula
+is executing.
+
+If you are having problems with ClientRunBeforeJob scripts randomly dying,
+it is possible that you have run into an Oracle bug. See bug number 622 in
+the bugs.bacula.org database. The following information has been
+provided by a user on this issue:
+
+\footnotesize
+\begin{verbatim}
+The information in this document applies to:
+ Oracle HTTP Server - Version: 9.0.4
+ Microsoft Windows Server 2003
+ Symptoms
+ When starting an OC4J instance, the System Clock runs faster, about 7
+seconds per minute.
+
+ Cause
+
+ + This is caused by the Sun JVM bug 4500388, which states that "Calling
+Thread.sleep() with a small argument affects the system clock". Although
+this is reported as fixed in JDK 1.4.0_02, several reports contradict this
+(see the bug in
+http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4500388).
+
+ + Also reported by Microsoft as "The system clock may run fast when you
+use the ACPI power management timer as a high-resolution counter on Windows
+2000-based computers" (See http://support.microsoft.com/?id=821893)
+\end{verbatim}
+\normalsize
+
+You may wish to start the daemon with debug mode on rather than doing it
+using bconsole. To do so, edit the following registry key:
+
+\footnotesize
+\begin{verbatim}
+HKEY_LOCAL_MACHINE\HARDWARE\SYSTEM\CurrentControlSet\Services\Bacula-dir
+\end{verbatim}
+\normalsize
+
+using regedit, then add -dnn after the /service option, where nn represents
+the debug level you want.
+
+\label{Compatibility}
+\section{Windows Compatibility Considerations}
+\index[general]{Windows Compatibility Considerations}
+\index[general]{Considerations!Windows Compatibility}
+
+If you are not using the VSS (Volume Shadow Copy) option described in the
+next section of this chapter, and if any applications are running during
+the backup and they have files opened exclusively, Bacula will not be able
+to backup those files, so be sure you close your applications (or tell your
+users to close their applications) before the backup. Fortunately, most
+Microsoft applications do not open files exclusively so that they can be
+backed up. However, you will need to experiment. In any case, if Bacula
+cannot open the file, it will print an error message, so you will always
+know which files were not backed up. For version 1.37.25 and greater, see
+the section below on Volume Shadow Copy Service that permits backing up any
+file.
+
+During backup, Bacula doesn't know about the system registry, so you will
+either need to write it out to an ASCII file using {\bf regedit~~/e} or use a
+program specifically designed to make a copy or backup the registry.
+
+In Bacula version 1.31 and later, we use Windows backup API calls by
+default. Typical of Windows, programming these special BackupRead and
+BackupWrite calls is a real nightmare of complications. The end result
+gives some distinct advantages and some disadvantages.
+
+First, the advantages are that on WinNT/2K/XP systems, the security and
+ownership information is now backed up. In addition, with the exception of
+files in exclusive use by another program, Bacula can now access all system
+files. This means that when you restore files, the security and ownership
+information will be restored on WinNT/2K/XP along with the data.
+
+The disadvantage of the Windows backup API calls is that it produces
+non-portable backups. That is files and their data that are backed up on
+WinNT using the native API calls (BackupRead/BackupWrite) cannot be
+restored on Win95/98/Me or Unix systems. In principle, a file backed up on
+WinNT can be restored on WinXP, but this remains to be seen in practice
+(not yet tested). Bacula should be able to read non-portable
+backups on any system and restore the data appropriately. However,
+on a system that does not have the BackupRead/BackupWrite calls (older
+Windows versions and all Unix/Linux machines), though the file data
+can be restored, the Windows security and access control data will not be restored.
+This means that a standard set of access permissions will be set for
+such restored files.
+
+
+As a default, Bacula backs up Windows systems using the Windows API calls.
+If you want to backup data on a WinNT/2K/XP system and restore it on a
+Unix/Win95/98/Me system, we have provided a special {\bf portable} option
+that backs up the data in a portable fashion by using portable API calls.
+See the \ilink{portable option}{portable} on the Include statement in a
+FileSet resource in the Director's configuration chapter for the details on
+setting this option. However, using the portable option means you may have
+permissions problems accessing files, and none of the security and
+ownership information will be backed up or restored. The file data can,
+however, be restored on any system.
+
+You should always be able to restore any file backed up on Unix or Win95/98/Me
+to any other system. On some systems, such as WinNT/2K/XP, you may have to
+reset the ownership of such restored files. Any file backed up on WinNT/2K/XP
+should in principle be able to be restored to a similar system (i.e.
+WinNT/2K/XP), however, I am unsure of the consequences if the owner
+information and accounts are not identical on both systems. Bacula will not
+let you restore files backed up on WinNT/2K/XP to any other system (i.e. Unix
+Win95/98/Me) if you have used the defaults.
+
+Finally, if you specify the {\bf portable=yes} option on the files you back
+up. Bacula will be able to restore them on any other system. However, any
+WinNT/2K/XP specific security and ownership information will be lost.
+
+The following matrix will give you an idea of what you can expect. Thanks to
+Marc Brueckner for doing the tests:

+\label{VSS}
+\section{Volume Shadow Copy Service}
+\index[general]{Volume Shadow Copy Service}
+\index[general]{VSS}
+In version 1.37.30 and greater, you can turn on Microsoft's Volume
+Shadow Copy Service (VSS).
+
+Microsoft added VSS to Windows XP and Windows 2003. From the perspective of
+a backup-solution for Windows, this is an extremely important step. VSS
+allows Bacula to backup open files and even to interact with applications like
+RDBMS to produce consistent file copies. VSS aware applications are called
+VSS Writers, they register with the OS so that when Bacula wants to do a
+Snapshot, the OS will notify the register Writer programs, which may then
+create a consistent state in their application, which will be backed up.
+Examples for these writers are "MSDE" (Microsoft database
+engine), "Event Log Writer", "Registry Writer" plus 3rd
+party-writers. If you have a non-vss aware application (e.g.
+SQL Anywhere or probably MySQL), a shadow copy is still generated
+and the open files can be backed up, but there is no guarantee
+that the file is consistent.
+
+Bacula produces a message from each of the registered writer programs
+when it is doing a VSS backup so you know which ones are correctly backed
+up.
+
+Bacula supports VSS on both Windows 2003 and Windows XP.
+Technically Bacula creates a shadow copy as soon as the backup process
+starts. It does then backup all files from the shadow copy and destroys the
+shadow copy after the backup process. Please have in mind, that VSS
+creates a snapshot and thus backs up the system at the state it had
+when starting the backup. It will disregard file changes which occur during
+the backup process.
+
+VSS can be turned on by placing an
+
+\index[dir]{Enable VSS}
+\index[general]{Enable VSS}
+\begin{verbatim}
+Enable VSS = yes
+\end{verbatim}
+
+in your FileSet resource.
+
+The VSS aware File daemon has the letters VSS on the signon line that
+it produces when contacted by the console. For example:
+\begin{verbatim}
+Tibs-fd Version: 1.37.32 (22 July 2005) VSS Windows XP MVS NT 5.1.2600
+\end{verbatim}
+the VSS is shown in the line above. This only means that the File daemon
+is capable of doing VSS not that VSS is turned on for a particular backup.
+There are two ways of telling if VSS is actually turned on during a backup.
+The first is to look at the status output for a job, e.g.:
+\footnotesize
+\begin{verbatim}
+Running Jobs:
+JobId 1 Job NightlySave.2005-07-23_13.25.45 is running.
+ VSS Backup Job started: 23-Jul-05 13:25
+ Files=70,113 Bytes=3,987,180,650 Bytes/sec=3,244,247
+ Files Examined=75,021
+ Processing file: c:/Documents and Settings/kern/My Documents/My Pictures/Misc1/Sans titre - 39.pdd
+ SDReadSeqNo=5 fd=352
+\end{verbatim}
+\normalsize
+Here, you see under Running Jobs that JobId 1 is "VSS Backup Job started ..."
+This means that VSS is enabled for that job. If VSS is not enabled, it will
+simply show "Backup Job started ..." without the letters VSS.
+
+The second way to know that the job was backed up with VSS is to look at the
+Job Report, which will look something like the following:
+\footnotesize
+\begin{verbatim}
+23-Jul 13:25 rufus-dir: Start Backup JobId 1, Job=NightlySave.2005-07-23_13.25.45
+23-Jul 13:26 rufus-sd: Wrote label to prelabeled Volume "TestVolume001" on device "DDS-4" (/dev/nst0)
+23-Jul 13:26 rufus-sd: Spooling data ...
+23-Jul 13:26 Tibs: Generate VSS snapshots. Driver="VSS WinXP", Drive(s)="C"
+23-Jul 13:26 Tibs: VSS Writer: "MSDEWriter", State: 1 (VSS_WS_STABLE)
+23-Jul 13:26 Tibs: VSS Writer: "Microsoft Writer (Bootable State)", State: 1 (VSS_WS_STABLE)
+23-Jul 13:26 Tibs: VSS Writer: "WMI Writer", State: 1 (VSS_WS_STABLE)
+23-Jul 13:26 Tibs: VSS Writer: "Microsoft Writer (Service State)", State: 1 (VSS_WS_STABLE)
+\end{verbatim}
+\normalsize
+In the above Job Report listing, you see that the VSS snapshot was generated for drive C (if
+other drives are backed up, they will be listed on the {\bf Drive(s)="C"} You also see the
+reports from each of the writer program. Here they all report VSS\_WS\_STABLE, which means
+that you will get a consistent snapshot of the data handled by that writer.
+
+\section{VSS Problems}
+\index[general]{Problems!VSS}
+\index[fd] {Problems!VSS}
+\index[general]{VSS Problems}
+\index[fd]{VSS Problems}
+
+If you are experiencing problems such as VSS hanging on MSDE, first try
+running {\bf vssadmin} to check for problems, then try running {\bf
+ntbackup} which also uses VSS to see if it has similar problems. If so, you
+know that the problem is in your Windows machine and not with Bacula.
+
+The FD hang problems were reported with {\bf MSDEwriter} when:
+\begin{itemize}
+\item a local firewall locked local access to the MSDE TCP port (MSDEwriter
+seems to use TCP/IP and not Named Pipes).
+\item msdtcs was installed to run under "localsystem": try running msdtcs
+under networking account (instead of local system) (com+ seems to work
+better with this configuration).
+\end{itemize}
+
+
+\section{Windows Firewalls}
+\index[general]{Firewalls!Windows}
+\index[general]{Windows Firewalls}
+
+If you turn on the firewalling feature on Windows (default in WinXP SP2), you
+are likely to find that the Bacula ports are blocked and you cannot
+communicate to the other daemons. This can be deactivated through the {\bf
+Security Notification} dialog, which is apparently somewhere in the {\bf
+Security Center}. I don't have this on my computer, so I cannot give the exact
+details.
+
+The command:
+
+\footnotesize
+\begin{verbatim}
+netsh firewall set opmode disable
+\end{verbatim}
+\normalsize
+
+is purported to disable the firewall, but this command is not accepted on my
+WinXP Home machine.
+
+\section{Windows Port Usage}
+\index[general]{Windows Port Usage}
+\index[general]{Usage!Windows Port}
+
+If you want to see if the File daemon has properly opened the port and is
+listening, you can enter the following command in a shell window:
+
+\footnotesize
+\begin{verbatim}
+ netstat -an | findstr 910[123]
+\end{verbatim}
+\normalsize
+
+TopView is another program that has been recommend, but it is not a
+standard Win32 program, so you must find and download it from the Internet.
+
+\section{Windows Disaster Recovery}
+\index[general]{Recovery!Windows Disaster}
+\index[general]{Windows Disaster Recovery}
+
+We don't currently have a good solution for disaster recovery on Windows as we
+do on Linux. The main piece lacking is a Windows boot floppy or a Windows boot
+CD. Microsoft releases a Windows Pre-installation Environment ({\bf WinPE})
+that could possibly work, but we have not investigated it. This means that
+until someone figures out the correct procedure, you must restore the OS from
+the installation disks, then you can load a Bacula client and restore files.
+Please don't count on using {\bf bextract} to extract files from your backup
+tapes during a disaster recovery unless you have backed up those files using
+the {\bf portable} option. {\bf bextract} does not run on Windows, and the
+normal way Bacula saves files using the Windows API prevents the files from
+being restored on a Unix machine. Once you have an operational Windows OS
+loaded, you can run the File daemon and restore your user files.
+
+Please see
+\ilink{ Disaster Recovery of Win32 Systems}{Win3233} for the latest
+suggestion, which looks very promising.
+
+It looks like Bart PE Builder, which creates a Windows PE (Pre-installation
+Environment) Boot-CD, may be just what is needed to build a complete disaster
+recovery system for Win32. This distribution can be found at
+\elink{http://www.nu2.nu/pebuilder/}{\url{http://www.nu2.nu/pebuilder/}}.

+\section{Windows Restore Problems}
+\index[general]{Problems!Windows Restore}
+\index[general]{Windows Restore Problems}
+Please see the
+\ilink{Restore Chapter}{Windows} of this manual for problems
+that you might encounter doing a restore.
+
+section{Windows Backup Problems}
+\index[general]{Problems!Windows Backup}
+\index[general]{Windows Backup Problems}
+If during a Backup, you get the message:
+{\bf ERR=Access is denied} and you are using the portable option,
+you should try both adding both the non-portable (backup API) and
+the Volume Shadow Copy options to your Director's conf file.
+
+In the Options resource:
+\footnotesize
+\begin{verbatim}
+portable = no
+\end{verbatim}
+\normalsize
+
+In the FileSet resource:
+\footnotesize
+\begin{verbatim}
+enablevss = yes
+\end{verbatim}
+\normalsize
+
+In general, specifying these two options should allow you to backup
+any file on a Windows system. However, in some cases, if users
+have allowed to have full control of their folders, even system programs
+such a Bacula can be locked out. In this case, you must identify
+which folders or files are creating the problem and do the following:
+
+\begin{enumerate}
+\item Grant ownership of the file/folder to the Administrators group,
+with the option to replace the owner on all child objects.
+\item Grant full control permissions to the Administrators group,
+and change the user's group to only have Modify permission to
+the file/folder and all child objects.
+\end{enumerate}
+
+Thanks to Georger Araujo for the above information.
+
+\section{Windows Ownership and Permissions Problems}
+\index[general]{Problems!Windows Ownership and Permissions}
+\index[general]{Windows Ownership and Permissions Problems}
+
+If you restore files backed up from WinNT/XP/2K to an alternate directory,
+Bacula may need to create some higher level directories that were not saved
+(or restored). In this case, the File daemon will create them under the SYSTEM
+account because that is the account that Bacula runs under as a service. As of
+version 1.32f-3, Bacula creates these files with full access permission.
+However, there may be cases where you have problems accessing those files even
+if you run as administrator. In principle, Microsoft supplies you with the way
+to cease the ownership of those files and thus change the permissions.
+However, a much better solution to working with and changing Win32 permissions
+is the program {\bf SetACL}, which can be found at
+\elink{http://setacl.sourceforge.net/}{\url{http://setacl.sourceforge.net/}}.
+
+If you have not installed Bacula while running as Administrator
+and if Bacula is not running as a Process with the userid (User Name) SYSTEM,
+then it is very unlikely that it will have sufficient permission to
+access all your files.
+
+Some users have experienced problems restoring files that participate in
+the Active Directory. They also report that changing the userid under which
+Bacula (bacula-fd.exe) runs, from SYSTEM to a Domain Admin userid, resolves
+the problem.
+
+
+\section{Manually resetting the Permissions}
+\index[general]{Manually resetting the Permissions}
+\index[general]{Permissions!Manually resetting the}
+
+The following solution was provided by Dan Langille \lt{}dan at langille in
+the dot org domain\gt{}. The steps are performed using Windows 2000 Server but
+they should apply to most Win32 platforms. The procedure outlines how to deal
+with a problem which arises when a restore creates a top-level new directory.
+In this example, "top-level" means something like {\bf
+c:\textbackslash{}src}, not {\bf c:\textbackslash{}tmp\textbackslash{}src}
+where {\bf c:\textbackslash{}tmp} already exists. If a restore job specifies /
+as the {\bf Where:} value, this problem will arise.
+
+The problem appears as a directory which cannot be browsed with Windows
+Explorer. The symptoms include the following message when you try to click on
+that directory:
+
+\includegraphics{\idir access-is-denied.eps}
+
+If you encounter this message, the following steps will change the permissions
+to allow full access.
+
+\begin{enumerate}
+\item right click on the top level directory (in this example, {\bf c:/src})
+ and select {\bf Properties}.
+\item click on the Security tab.
+\item If the following message appears, you can ignore it, and click on {\bf
+ OK}.
+
+\includegraphics{\idir view-only.eps}
+
+You should see something like this:
+
+\includegraphics{\idir properties-security.eps}
+\item click on Advanced
+\item click on the Owner tab
+\item Change the owner to something other than the current owner (which is
+ {\bf SYSTEM} in this example as shown below).
+
+\includegraphics{\idir properties-security-advanced-owner.eps}
+\item ensure the "Replace owner on subcontainers and objects" box is
+ checked
+\item click on OK
+\item When the message "You do not have permission to read the contents of
+ directory c:\textbackslash{}src\textbackslash{}basis. Do you wish to replace
+ the directory permissions with permissions granting you Full Control?", click
+on Yes.
+
+\includegraphics{\idir confirm.eps}
+\item Click on OK to close the Properties tab
+ \end{enumerate}
+
+With the above procedure, you should now have full control over your restored
+directory.
+
+In addition to the above methods of changing permissions, there is a Microsoft
+program named {\bf cacls} that can perform similar functions.
+
+\section{Backing Up the WinNT/XP/2K System State}
+\index[general]{State!Backing Up the WinNT/XP/2K System}
+\index[general]{Backing Up the WinNT/XP/2K System State}
+
+A suggestion by Damian Coutts using Microsoft's NTBackup utility in
+conjunction with Bacula should permit a full restore of any damaged system
+files on Win2K/XP. His suggestion is to do an NTBackup of the critical system
+state prior to running a Bacula backup with the following command:
+
+\footnotesize
+\begin{verbatim}
+ntbackup backup systemstate /F c:\systemstate.bkf
+\end{verbatim}
+\normalsize
+
+The {\bf backup} is the command, the {\bf systemstate} says to backup only the
+system state and not all the user files, and the {\bf /F
+c:\textbackslash{}systemstate.bkf} specifies where to write the state file.
+this file must then be saved and restored by Bacula.
+
+To restore the system state, you first reload a base operating system if the
+OS is damaged, otherwise, this is not necessary, then you would use Bacula to
+restore all the damaged or lost user's files and to recover the {\bf
+c:\textbackslash{}systemstate.bkf} file. Finally if there are any damaged or
+missing system files or registry problems, you run {\bf NTBackup} and {\bf
+catalogue} the system statefile, and then select it for restore. The
+documentation says you can't run a command line restore of the systemstate.
+
+To the best of my knowledge, this has not yet been tested. If you test it,
+please report your results to the Bacula email list.
+
+\section{Considerations for Filename Specifications}
+\index[general]{Windows!Considerations for Filename Specifications}
+
+Please see the
+\ilink{Director's Configuration chapter}{win32} of this manual
+for important considerations on how to specify Windows paths in Bacula FileSet
+Include and Exclude directives.
+
+\index[general]{Unicode}
+Bacula versions prior to 1.37.28 do not support Windows Unicode filenames.
+As of that version, both {\bf bconsole} and {\bf bwx-console} support Windows
+Unicode filenames. There may still be some problems with multiple byte
+characters (e.g. Chinese, ...) where it is a two byte character but the
+displayed character is not two characters wide.
+
+\index[general]{Win32 Path Length Restriction}
+Path/filenames longer than 260 characters (up to 32,000) are supported
+beginning with Bacula version 1.39.20. Older Bacula versions support
+only 260 character path/filenames.
+
+\section{Win32 Specific File daemon Command Line}
+\index[general]{Client!Win32 Specific File daemon Command Line Options}
+\index[general]{Win32 Specific File daemon Command Line Options}
+
+These options are not normally seen or used by the user, and are documented
+here only for information purposes. At the current time, to change the default
+options, you must either manually run {\bf Bacula} or you must manually edit
+the system registry and modify the appropriate entries.
+
+In order to avoid option clashes between the options necessary for {\bf
+Bacula} to run on Windows and the standard Bacula options, all Windows
+specific options are signaled with a forward slash character (/), while as
+usual, the standard Bacula options are signaled with a minus (-), or a minus
+minus (\verb:--:). All the standard Bacula options can be used on the Windows
+version. In addition, the following Windows only options are implemented:
+
+\begin{description}
+
+\item [/service ]
+ \index[fd]{/service}
+ Start Bacula as a service
+
+\item [/run ]
+ \index[fd]{/run}
+ Run the Bacula application
+
+\item [/install ]
+ \index[fd]{/install}
+ Install Bacula as a service in the system registry
+
+\item [/remove ]
+ \index[fd]{/remove}
+ Uninstall Bacula from the system registry
+
+\item [/about ]
+ \index[fd]{/about}
+ Show the Bacula about dialogue box
+
+\item [/status ]
+ \index[fd]{/status}
+ Show the Bacula status dialogue box
+
+\item [/events ]
+ \index[fd]{/events}
+ Show the Bacula events dialogue box (not yet implemented)
+
+\item [/kill ]
+ \index[fd]{/kill}
+ Stop any running {\bf Bacula}
+
+\item [/help ]
+ \index[fd]{/help}
+ Show the Bacula help dialogue box
+\end{description}
+
+It is important to note that under normal circumstances the user should never
+need to use these options as they are normally handled by the system
+automatically once Bacula is installed. However, you may note these options in
+some of the .bat files that have been created for your use.

+\chapter{Bacula Console}
+\label{_ConsoleChapter}
+\index[general]{Console!Bacula}
+\index[general]{Bacula Console}
+\index[general]{Console!Bacula}
+\index[general]{Bacula Console}
+
+The {\bf Bacula Console} (sometimes called the User Agent) is a program that
+allows the user or the System Administrator, to interact with the Bacula
+Director daemon while the daemon is running.
+
+The current Bacula Console comes in two versions: a shell interface (TTY
+style), and a GNOME GUI interface. Both permit the administrator or authorized
+users to interact with Bacula. You can determine the status of a particular
+job, examine the contents of the Catalog as well as perform certain tape
+manipulations with the Console program.
+
+In addition, there is a bwx-console built with wxWidgets that allows a graphic
+restore of files. As of version 1.34.1 it is in an early stage of development,
+but it already is quite useful. Unfortunately, it has not been enhanced for
+some time now.
+
+Since the Console program interacts with the Director through the network, your
+Console and Director programs do not necessarily need to run on the same
+machine.
+
+In fact, a certain minimal knowledge of the Console program is needed in order
+for Bacula to be able to write on more than one tape, because when Bacula
+requests a new tape, it waits until the user, via the Console program,
+indicates that the new tape is mounted.
+
+\section{Console Configuration}
+\index[general]{Console Configuration}
+\index[general]{Configuration!Console}
+\index[general]{Console Configuration}
+\index[general]{Configuration!Console}
+
+When the Console starts, it reads a standard Bacula configuration file
+named {\bf bconsole.conf} or {\bf bgnome-console.conf} in the case of the GNOME
+Console version from the current directory unless you specify the {\bf {-}c}
+command line option (see below). This file allows default configuration
+of the Console, and at the current time, the only Resource Record defined
+is the Director resource, which gives the Console the name and address of
+the Director. For more information on configuration of the Console
+program, please see the \ilink{Console Configuration
+File}{ConsoleConfChapter} Chapter of this document.
+
+\section{Running the Console Program}
+\index[general]{Running the Console Program}
+\index[general]{Program!Running the Console}
+\index[general]{Running the Console Program}
+\index[general]{Program!Running the Console}
+
+The console program can be run with the following options:
+\footnotesize
+\begin{verbatim}
+Usage: bconsole [-s] [-c config_file] [-d debug_level]
+ -c <file> set configuration file to file
+ -dnn set debug level to nn
+ -n no conio
+ -s no signals
+ -t test - read configuration and exit
+ -? print this message.
+\end{verbatim}
+\normalsize
+
+
+After launching the Console program (bconsole), it will prompt you for the
+next command with an asterisk (*). (Note, in the GNOME version, the prompt is
+not present; you simply enter the commands you want in the command text box at
+the bottom of the screen.) Generally, for all commands, you can simply enter
+the command name and the Console program will prompt you for the necessary
+arguments. Alternatively, in most cases, you may enter the command followed by
+arguments. The general format is:
+
+\footnotesize
+\begin{verbatim}
+ <command> <keyword1>[=<argument1>] <keyword2>[=<argument2>] ...
+\end{verbatim}
+\normalsize
+
+where {\bf command} is one of the commands listed below; {\bf keyword} is one
+of the keywords listed below (usually followed by an argument); and {\bf
+argument} is the value. The command may be abbreviated to the shortest unique
+form. If two commands have the same starting letters, the one that will be
+selected is the one that appears first in the {\bf help} listing. If you want
+the second command, simply spell out the full command. None of the keywords
+following the command may be abbreviated.
+
+For example:
+
+\footnotesize
+\begin{verbatim}
+list files jobid=23
+\end{verbatim}
+\normalsize
+
+will list all files saved for JobId 23. Or:
+
+\footnotesize
+\begin{verbatim}
+show pools
+\end{verbatim}
+\normalsize
+
+will display all the Pool resource records.
+
+The maximum command line length is limited to 511 characters, so if you
+are scripting the console, you may need to take some care to limit the
+line length.
+
+\section{Stopping the Console Program}
+\index[general]{Program!Stopping the Console}
+\index[general]{Stopping the Console Program}
+\index[general]{Program!Stopping the Console}
+\index[general]{Stopping the Console Program}
+
+Normally, you simply enter {\bf quit} or {\bf exit} and the Console program
+will terminate. However, it waits until the Director acknowledges the command.
+If the Director is already doing a lengthy command (e.g. prune), it may take
+some time. If you want to immediately terminate the Console program, enter the
+{\bf .quit} command.
+
+There is currently no way to interrupt a Console command once issued (i.e.
+Ctrl-C does not work). However, if you are at a prompt that is asking you to
+select one of several possibilities and you would like to abort the command,
+you can enter a period ({\bf .}), and in most cases, you will either be
+returned to the main command prompt or if appropriate the previous prompt (in
+the case of nested prompts). In a few places such as where it is asking for a
+Volume name, the period will be taken to be the Volume name. In that case, you
+will most likely be able to cancel at the next prompt.
+

+\index[general]{Keywords!Alphabetic List of Console}
+\index[general]{Alphabetic List of Console Keywords}
+Unless otherwise specified, each of the following keywords
+takes an argument, which is specified after the keyword following
+an equal sign. For example:
+
+\begin{verbatim}
+jobid=536
+\end{verbatim}
+
+Please note, this list is incomplete as it is currently in
+the process of being created and is not currently totally in
+alphabetic
+order ...
+
+\begin{description}
+\item [restart]
+ Permitted on the python command, and causes the Python
+ interpreter to be restarted. Takes no argument.
+\item [all]
+ Permitted on the status and show commands to specify all components or
+ resources respectively.
+\item [allfrompool]
+ Permitted on the update command to specify that all Volumes in the
+ pool (specified on the command line) should be updated.
+\item [allfrompools]
+ Permitted on the update command to specify that all Volumes in all
+ pools should be updated.
+\item [before]
+ Used in the restore command.
+\item [bootstrap]
+ Used in the restore command.
+\item [catalog]
+ Allowed in the use command to specify the catalog name
+ to be used.
+\item [catalogs]
+ Used in the show command. Takes no arguments.
+\item [client | fd]
+\item [clients]
+ Used in the show, list, and llist commands. Takes no arguments.
+\item [counters]
+ Used in the show command. Takes no arguments.
+\item [current]
+ Used in the restore command. Takes no argument.
+\item [days]
+ Used to define the number of days the "list nextvol" command
+ should consider when looking for jobs to be run. The days keyword
+ can also be used on the "status dir" command so that it will display
+ jobs scheduled for the number of days you want.
+\item [devices]
+ Used in the show command. Takes no arguments.
+\item [dir | director]
+\item [directors]
+ Used in the show command. Takes no arguments.
+\item [directory]
+ Used in the restore command. Its argument specifies the directory
+ to be restored.
+\item [enabled]
+ This keyword can appear on the {\bf update volume} as well
+ as the {\bf update slots} commands, and can
+ allows one of the following arguments: yes, true, no, false, archived,
+ 0, 1, 2. Where 0 corresponds to no or false, 1 corresponds to yes or true, and
+ 2 corresponds to archived. Archived volumes will not be used, nor will
+ the Media record in the catalog be pruned. Volumes that are not enabled,
+ will not be used for backup or restore.
+\item [done]
+ Used in the restore command. Takes no argument.
+\item [file]
+ Used in the restore command.
+\item [files]

+\item [jobtotals]
+ Used in the list and llist commands. Takes no arguments.
+\item [jobid]
+ The JobId is the numeric jobid that is printed in the Job
+ Report output. It is the index of the database record for the
+ given job. While it is unique for all the existing Job records
+ in the catalog database, the same JobId can be reused once a
+ Job is removed from the catalog. Probably you will refer
+ specific Jobs that ran using their numeric JobId.
+\item [job | jobname]
+ The Job or Jobname keyword refers to the name you specified
+ in the Job resource, and hence it refers to any number of
+ Jobs that ran. It is typically useful if you want to list
+ all jobs of a particular name.
+\item [level]
+\item [listing]
+ Permitted on the estimate command. Takes no argument.
+\item [limit]
+\item [messages]
+ Used in the show command. Takes no arguments.

+\item [nextvol | nextvolume]
+ Used in the list and llist commands. Takes no arguments.
+\item [on]
+ Takes no keyword.
+\item [off]
+ Takes no keyword.
+\item [pool]
+\item [pools]
+ Used in the show, list, and llist commands. Takes no arguments.
+\item [select]
+ Used in the restore command. Takes no argument.
+\item [storages]
+ Used in the show command. Takes no arguments.
+\item [schedules]

+ in the Job Report output. At the current time, it consists
+ of the Job name (from the Name directive for the job) appended
+ with the date and time the job was run. This keyword is useful
+ if you want to completely identify the Job instance run.
+\item [volume]
+\item [volumes]
+ Used in the list and llist commands. Takes no arguments.
+\item [where]
+ Used in the restore command.
+\item [yes]

+\index[general]{Commands!Alphabetic List of Console}
+\index[general]{Alphabetic List of Console Commands}
+\index[general]{Commands!Alphabetic List of Console}
+\index[general]{Alphabetic List of Console Commands}
+
+The following commands are currently implemented:
+
+\begin{description}
+\item [{add [pool=\lt{}pool-name\gt{} storage=\lt{}storage\gt{}
+ jobid=\lt{}JobId\gt{}]} ]
+ \index[general]{add}
+ This command is used to add Volumes to an existing Pool. That is,
+ it creates the Volume name in the catalog and inserts into the Pool
+ in the catalog, but does not attempt to access the physical Volume.
+ Once
+ added, Bacula expects that Volume to exist and to be labeled.
+ This command is not normally used since Bacula will
+ automatically do the equivalent when Volumes are labeled. However,
+ there may be times when you have removed a Volume from the catalog
+ and want to later add it back.
+
+ Normally, the {\bf label} command is used rather than this command
+ because the {\bf label} command labels the physical media (tape, disk,
+ DVD, ...) and does the equivalent of the {\bf add} command. The {\bf
+ add} command affects only the Catalog and not the physical media (data
+ on Volumes). The physical media must exist and be labeled before use
+ (usually with the {\bf label} command). This command can, however, be
+ useful if you wish to add a number of Volumes to the Pool that will be
+ physically labeled at a later time. It can also be useful if you are
+ importing a tape from another site. Please see the {\bf label} command
+ below for the list of legal characters in a Volume name.
+
+\item [autodisplay on/off]
+ \index[general]{autodisplay on/off}
+ This command accepts {\bf on} or {\bf off} as an argument, and turns
+ auto-display of messages on or off respectively. The default for the
+ console program is {\bf off}, which means that you will be notified when
+ there are console messages pending, but they will not automatically be
+ displayed. The default for the bgnome-console program is {\bf on}, which
+ means that messages will be displayed when they are received (usually
+ within five seconds of them being generated).
+
+ When autodisplay is turned off, you must explicitly retrieve the
+ messages with the {\bf messages} command. When autodisplay is turned
+ on, the messages will be displayed on the console as they are received.
+
+\item [automount on/off]
+ \index[general]{automount on/off}
+ This command accepts {\bf on} or {\bf off} as the argument, and turns
+ auto-mounting of the Volume after a {\bf label} command on or off
+ respectively. The default is {\bf on}. If {\bf automount} is turned
+ off, you must explicitly {\bf mount} tape Volumes after a label command to
+ use it.
+
+\item [{cancel [jobid=\lt{}number\gt{} job=\lt{}job-name\gt{} ujobid=\lt{}unique-jobid\gt{}]}]
+ \index[general]{cancel jobid}
+ This command is used to cancel a job and accepts {\bf jobid=nnn} or {\bf
+ job=xxx} as an argument where nnn is replaced by the JobId and xxx is
+ replaced by the job name. If you do not specify a keyword, the Console
+ program will prompt you with the names of all the active jobs allowing
+ you to choose one.
+
+ Once a Job is marked to be canceled, it may take a bit of time
+ (generally within a minute but up to two hours) before the Job actually
+ terminates, depending on what operations it is doing.
+ Don't be surprised that you receive a Job not found message. That just
+ means that one of the three daemons had already canceled the job.
+ Messages numbered in the 1000's are from the Director, 2000's are from
+ the File daemon and 3000's from the Storage daemon.
+
+
+\item [{create [pool=\lt{}pool-name\gt{}]}]
+ \index[general]{create pool}
+ This command is not normally used as the Pool records are automatically
+ created by the Director when it starts based on what it finds in
+ the conf file. If needed, this command can be
+ to create a Pool record in the database using the
+ Pool resource record defined in the Director's configuration file. So
+ in a sense, this command simply transfers the information from the Pool
+ resource in the configuration file into the Catalog. Normally this
+ command is done automatically for you when the Director starts providing
+ the Pool is referenced within a Job resource. If you use this command
+ on an existing Pool, it will automatically update the Catalog to have
+ the same information as the Pool resource. After creating a Pool, you
+ will most likely use the {\bf label} command to label one or more
+ volumes and add their names to the Media database.
+
+ When starting a Job, if Bacula determines that there is no Pool record
+ in the database, but there is a Pool resource of the appropriate name,
+ it will create it for you. If you want the Pool record to appear in the
+ database immediately, simply use this command to force it to be created.
+
+\item [{delete [volume=\lt{}vol-name\gt{} pool=\lt{}pool-name\gt{} job
+ jobid=\lt{}id\gt{}]}]
+ \index[general]{delete}
+ The delete command is used to delete a Volume, Pool or Job record from
+ the Catalog as well as all associated catalog Volume records that were
+ created. This command operates only on the Catalog database and has no
+ effect on the actual data written to a Volume. This command can be
+ dangerous and we strongly recommend that you do not use it unless you
+ know what you are doing.
+
+ If the keyword {\bf Volume} appears on the command line, the named
+ Volume will be deleted from the catalog, if the keyword {\bf Pool}
+ appears on the command line, a Pool will be deleted, and if the keyword
+ {\bf Job} appears on the command line, a Job and all its associated
+ records (File and JobMedia) will be deleted from the catalog. The full
+ form of this command is:
+
+\begin{verbatim}
+delete pool=<pool-name>
+\end{verbatim}
+
+ or
+
+\begin{verbatim}
+delete volume=<volume-name> pool=<pool-name> or
+\end{verbatim}
+
+\begin{verbatim}
+delete JobId=<job-id> JobId=<job-id2> ... or
+\end{verbatim}
+
+\begin{verbatim}
+delete Job JobId=n,m,o-r,t ...
+\end{verbatim}
+
+ The first form deletes a Pool record from the catalog database. The
+ second form deletes a Volume record from the specified pool in the
+ catalog database. The third form deletes the specified Job record from
+ the catalog database. The last form deletes JobId records for JobIds
+ n, m, o, p, q, r, and t. Where each one of the n,m,... is, of course, a
+ number. That is a "delete jobid" accepts lists and ranges of
+ jobids.
+
+\item [disable job\lt{}job-name\gt{}]
+ \index[general]{disable}
+ This command permits you to disable a Job for automatic scheduling.
+ The job may have been previously enabled with the Job resource
+ {\bf Enabled} directive or using the console {\bf enable} command.
+ The next time the Director is restarted or the conf file is reloaded,
+ the Enable/Disable state will be set to the value in the Job resource
+ (default enabled) as defined in the bacula-dir.conf file.
+
+\item [enable job\lt{}job-name\gt{}]
+ \index[general]{enable}
+ This command permits you to enable a Job for automatic scheduling.
+ The job may have been previously disabled with the Job resource
+ {\bf Enabled} directive or using the console {\bf disable} command.
+ The next time the Director is restarted or the conf file is reloaded,
+ the Enable/Disable state will be set to the value in the Job resource
+ (default enabled) as defined in the bacula-dir.conf file.
+
+\label{estimate}
+\item [estimate]
+ \index[general]{estimate}
+ Using this command, you can get an idea how many files will be backed
+ up, or if you are unsure about your Include statements in your FileSet,
+ you can test them without doing an actual backup. The default is to
+ assume a Full backup. However, you can override this by specifying a
+ {\bf level=Incremental} or {\bf level=Differential} on the command line.
+ A Job name must be specified or you will be prompted for one, and
+ optionally a Client and FileSet may be specified on the command line.
+ It then contacts the client which computes the number of files and bytes
+ that would be backed up. Please note that this is an estimate
+ calculated from the number of blocks in the file rather than by reading
+ the actual bytes. As such, the estimated backup size will generally be
+ larger than an actual backup.
+
+ The estimate command isn't currently compatible with the Accurate mode, it
+ doesn't detect changes like with a backup using \textbf{Accurate=yes}.
+
+ Optionally you may specify the keyword {\bf listing} in which case, all the
+ files to be backed up will be listed. Note, it could take quite some time to
+ display them if the backup is large. The full form is:
+
+
+\begin{verbatim}
+estimate job=<job-name> listing client=<client-name>
+ fileset=<fileset-name> level=<level-name>
+\end{verbatim}
+
+ Specification of the {\bf job} is sufficient, but you can also override
+ the client, fileset and/or level by specifying them on the estimate
+ command line.
+
+
+As an example, you might do:
+
+\footnotesize
+\begin{verbatim}
+ @output /tmp/listing
+ estimate job=NightlySave listing level=Incremental
+ @output
+\end{verbatim}
+\normalsize
+
+ which will do a full listing of all files to be backed up for the Job {\bf
+ NightlySave} during an Incremental save and put it in the file {\bf
+ /tmp/listing}. Note, the byte estimate provided by this command is
+ based on the file size contained in the directory item. This can give
+ wildly incorrect estimates of the actual storage used if there are
+ sparse files on your systems. Sparse files are often found on 64 bit
+ systems for certain system files. The size that is returned is the size
+ Bacula will backup if the sparse option is not specified in the FileSet.
+ There is currently no way to get an estimate of the real file size that
+ would be found should the sparse option be enabled.
+
+\item [exit]
+ \index[general]{exit}
+ This command terminates the console program.
+
+\item [gui]
+ \index[general]{gui}
+ Invoke the non-interactive gui mode.
+\begin{verbatim}
+gui [on|off]
+\end{verbatim}
+
+\item [help]
+ \index[general]{help}
+ This command displays the list of commands available.
+
+\item [label]
+ \index[general]{label}
+ \index[general]{relabel}
+ \index[general]{label}
+ \index[general]{relabel}
+ This command is used to label physical volumes. The full form of this command
+ is:
+
+\begin{verbatim}
+label storage=<storage-name> volume=<volume-name>
+ slot=<slot>
+\end{verbatim}
+
+ If you leave out any part, you will be prompted for it. The media type
+ is automatically taken from the Storage resource definition that you
+ supply. Once the necessary information is obtained, the Console program
+ contacts the specified Storage daemon and requests that the Volume be
+ labeled. If the Volume labeling is successful, the Console program will
+ create a Volume record in the appropriate Pool.
+
+ The Volume name is restricted to letters, numbers, and the special
+ characters hyphen ({\bf -}), underscore ({\bf \_}), colon ({\bf :}), and
+ period ({\bf .}). All other characters including a space are invalid.
+ This restriction is to ensure good readability of Volume names to reduce
+ operator errors.
+
+ Please note, when labeling a blank tape, Bacula will get {\bf read I/O
+ error} when it attempts to ensure that the tape is not already labeled. If
+ you wish to avoid getting these messages, please write an EOF mark on
+ your tape before attempting to label it:
+
+\footnotesize
+\begin{verbatim}
+ mt rewind
+ mt weof
+
+\end{verbatim}
+\normalsize
+
+The label command can fail for a number of reasons:
+
+\begin{enumerate}
+\item The Volume name you specify is already in the Volume database.
+
+\item The Storage daemon has a tape or other Volume already mounted on the
+ device, in which case you must {\bf unmount} the device, insert a blank
+ tape, then do the {\bf label} command.
+
+\item The Volume in the device is already a Bacula labeled Volume. (Bacula will
+ never relabel a Bacula labeled Volume unless it is recycled and you use the
+ {\bf relabel} command).
+
+\item There is no Volume in the drive.
+\end{enumerate}
+
+There are two ways to relabel a volume that already has a Bacula label. The
+brute force method is to write an end of file mark on the tape using the
+system {\bf mt} program, something like the following:
+
+\footnotesize
+\begin{verbatim}
+ mt -f /dev/st0 rewind
+ mt -f /dev/st0 weof
+\end{verbatim}
+\normalsize
+
+For a disk volume, you would manually delete the Volume.
+
+Then you use the {\bf label} command to add a new label. However, this could
+leave traces of the old volume in the catalog.
+
+The preferable method to relabel a Volume is to first {\bf purge} the volume,
+either automatically, or explicitly with the {\bf purge} command, then use
+the {\bf relabel} command described below.
+
+If your autochanger has barcode labels, you can label all the Volumes in
+your autochanger one after another by using the {\bf label barcodes}
+command. For each tape in the changer containing a barcode, Bacula will
+mount the tape and then label it with the same name as the barcode. An
+appropriate Media record will also be created in the catalog. Any barcode
+that begins with the same characters as specified on the
+"CleaningPrefix=xxx" directive in the Director's Pool resource, will be
+treated as a cleaning tape, and will not be labeled. However, an entry for
+the cleaning tape will be created in the catalog. For example with:
+
+\footnotesize
+\begin{verbatim}
+ Pool {
+ Name ...
+ Cleaning Prefix = "CLN"
+ }
+
+\end{verbatim}
+\normalsize
+
+Any slot containing a barcode of CLNxxxx will be treated as a cleaning tape
+and will not be mounted. Note, the full form of the command is:
+
+\footnotesize
+\begin{verbatim}
+label storage=xxx pool=yyy slots=1-5,10 barcodes
+\end{verbatim}
+\normalsize
+
+\item [list]
+ \index[general]{list}
+ The list command lists the requested contents of the Catalog. The
+ various fields of each record are listed on a single line. The various
+ forms of the list command are:
+\footnotesize
+\begin{verbatim}
+ list jobs
+
+ list jobid=<id> (list jobid id)
+
+ list ujobid=<unique job name> (list job with unique name)
+
+ list job=<job-name> (list all jobs with "job-name")
+
+ list jobname=<job-name> (same as above)
+
+ In the above, you can add "limit=nn" to limit the output to
+ nn jobs.
+
+ list jobmedia
+
+ list jobmedia jobid=<id>
+
+ list jobmedia job=<job-name>
+
+ list files jobid=<id>
+
+ list files job=<job-name>
+
+ list pools
+
+ list clients
+
+ list jobtotals
+
+ list volumes
+
+ list volumes jobid=<id>
+
+ list volumes pool=<pool-name>
+
+ list volumes job=<job-name>
+
+ list volume=<volume-name>
+
+ list nextvolume job=<job-name>
+
+ list nextvol job=<job-name>
+
+ list nextvol job=<job-name> days=nnn
+
+\end{verbatim}
+\normalsize
+
+ What most of the above commands do should be more or less obvious. In
+ general if you do not specify all the command line arguments, the
+ command will prompt you for what is needed.
+
+ The {\bf list nextvol} command will print the Volume name to be used by
+ the specified job. You should be aware that exactly what Volume will be
+ used depends on a lot of factors including the time and what a prior job
+ will do. It may fill a tape that is not full when you issue this
+ command. As a consequence, this command will give you a good estimate
+ of what Volume will be used but not a definitive answer. In addition,
+ this command may have certain side effect because it runs through the
+ same algorithm as a job, which means it may automatically purge or
+ recycle a Volume. By default, the job specified must run within the
+ next two days or no volume will be found. You can, however, use the
+ {\bf days=nnn} specification to specify up to 50 days. For example,
+ if on Friday, you want to see what Volume will be needed on Monday,
+ for job MyJob, you would use {\bf list nextvol job=MyJob days=3}.
+
+ If you wish to add specialized commands that list the contents of the
+ catalog, you can do so by adding them to the {\bf query.sql} file.
+ However, this takes some knowledge of programming SQL. Please see the
+ {\bf query} command below for additional information. See below for
+ listing the full contents of a catalog record with the {\bf llist}
+ command.
+
+ As an example, the command {\bf list pools} might produce the following
+ output:
+
+\footnotesize
+\begin{verbatim}
++------+---------+---------+---------+----------+-------------+
+| PoId | Name | NumVols | MaxVols | PoolType | LabelFormat |
++------+---------+---------+---------+----------+-------------+
+| 1 | Default | 0 | 0 | Backup | * |
+| 2 | Recycle | 0 | 8 | Backup | File |
++------+---------+---------+---------+----------+-------------+
+\end{verbatim}
+\normalsize
+
+ As mentioned above, the {\bf list} command lists what is in the
+ database. Some things are put into the database immediately when Bacula
+ starts up, but in general, most things are put in only when they are
+ first used, which is the case for a Client as with Job records, etc.
+
+ Bacula should create a client record in the database the first time you
+ run a job for that client. Doing a {\bf status} will not cause a
+ database record to be created. The client database record will be
+ created whether or not the job fails, but it must at least start. When
+ the Client is actually contacted, additional info from the client will
+ be added to the client record (a "uname -a" output).
+
+ If you want to see what Client resources you have available in your conf
+ file, you use the Console command {\bf show clients}.
+
+\item [llist]
+ \index[general]{llist}
+ The llist or "long list" command takes all the same arguments that the
+ list command described above does. The difference is that the llist
+ command list the full contents of each database record selected. It
+ does so by listing the various fields of the record vertically, with one
+ field per line. It is possible to produce a very large number of output
+ lines with this command.
+
+ If instead of the {\bf list pools} as in the example above, you enter
+ {\bf llist pools} you might get the following output:
+
+\footnotesize
+\begin{verbatim}
+ PoolId: 1
+ Name: Default
+ NumVols: 0
+ MaxVols: 0
+ UseOnce: 0
+ UseCatalog: 1
+ AcceptAnyVolume: 1
+ VolRetention: 1,296,000
+ VolUseDuration: 86,400
+ MaxVolJobs: 0
+ MaxVolBytes: 0
+ AutoPrune: 0
+ Recycle: 1
+ PoolType: Backup
+ LabelFormat: *
+
+ PoolId: 2
+ Name: Recycle
+ NumVols: 0
+ MaxVols: 8
+ UseOnce: 0
+ UseCatalog: 1
+ AcceptAnyVolume: 1
+ VolRetention: 3,600
+ VolUseDuration: 3,600
+ MaxVolJobs: 1
+ MaxVolBytes: 0
+ AutoPrune: 0
+ Recycle: 1
+ PoolType: Backup
+ LabelFormat: File
+
+\end{verbatim}
+\normalsize
+
+\item [messages]
+ \index[general]{messages}
+ This command causes any pending console messages to be immediately displayed.
+
+\item [memory]
+ \index[general]{memory}
+ Print current memory usage.
+
+
+\item [mount]
+ \index[general]{mount}
+ The mount command is used to get Bacula to read a volume on a physical
+ device. It is a way to tell Bacula that you have mounted a tape and
+ that Bacula should examine the tape. This command is normally
+ used only after there was no Volume in a drive and Bacula requests you to mount a new
+ Volume or when you have specifically unmounted a Volume with the {\bf
+ unmount} console command, which causes Bacula to close the drive. If
+ you have an autoloader, the mount command will not cause Bacula to
+ operate the autoloader unless you specify a {\bf slot} and possibly a
+ {\bf drive}. The various forms of the mount command are:
+
+mount storage=\lt{}storage-name\gt{} [ slot=\lt{}num\gt{} ] [
+ drive=\lt{}num\gt{} ]
+
+mount [ jobid=\lt{}id\gt{} | job=\lt{}job-name\gt{} ]
+
+ If you have specified {\bf Automatic Mount = yes} in the Storage daemon's
+ Device resource, under most circumstances, Bacula will automatically access
+ the Volume unless you have explicitly {\bf unmount}ed it in the Console
+ program.
+
+\label{ManualPruning}
+\item [prune]
+ \index[general]{prune}
+ The Prune command allows you to safely remove expired database records from
+ Jobs, Volumes and Statistics. This command works only on the Catalog
+ database and does not affect data written to Volumes. In all cases, the
+ Prune command applies a retention period to the specified records. You can
+ Prune expired File entries from Job records; you can Prune expired Job
+ records from the database, and you can Prune both expired Job and File
+ records from specified Volumes.
+
+prune files|jobs|volume|stats client=\lt{}client-name\gt{}
+volume=\lt{}volume-name\gt{}
+
+ For a Volume to be pruned, the {\bf VolStatus} must be Full, Used, or
+ Append, otherwise the pruning will not take place.
+
+\item [purge]
+ \index[general]{purge}
+ The Purge command will delete associated Catalog database records from
+ Jobs and Volumes without considering the retention period. {\bf Purge}
+ works only on the Catalog database and does not affect data written to
+ Volumes. This command can be dangerous because you can delete catalog
+ records associated with current backups of files, and we recommend that
+ you do not use it unless you know what you are doing. The permitted
+ forms of {\bf purge} are:
+
+purge files jobid=\lt{}jobid\gt{}|job=\lt{}job-name\gt{}|client=\lt{}client-name\gt{}
+
+purge jobs client=\lt{}client-name\gt{} (of all jobs)
+
+purge volume|volume=\lt{}vol-name\gt{} (of all jobs)
+
+For the {\bf purge} command to work on Volume Catalog database records the
+{\bf VolStatus} must be Append, Full, Used, or Error.
+
+The actual data written to the Volume will be unaffected by this command.
+
+\item[python]
+ \index[general]{python}
+ The python command takes a single argument {\bf restart}:
+
+python restart
+
+ This causes the Python interpreter in the Director to be reinitialized.
+ This can be helpful for testing because once the Director starts and the
+ Python interpreter is initialized, there is no other way to make it
+ accept any changes to the startup script {\bf DirStartUp.py}. For more
+ details on Python scripting, please see the \ilink{Python
+ Scripting}{PythonChapter} chapter of this manual.
+
+\item [query]
+ \index[general]{query}
+ This command reads a predefined SQL query from the query file (the name and
+ location of the query file is defined with the QueryFile resource record in
+ the Director's configuration file). You are prompted to select a query from
+ the file, and possibly enter one or more parameters, then the command is
+ submitted to the Catalog database SQL engine.
+
+The following queries are currently available (version 2.2.7):
+
+\footnotesize
+\begin{verbatim}
+Available queries:
+1: List up to 20 places where a File is saved regardless of the directory
+2: List where the most recent copies of a file are saved
+3: List last 20 Full Backups for a Client
+4: List all backups for a Client after a specified time
+5: List all backups for a Client
+6: List Volume Attributes for a selected Volume
+7: List Volumes used by selected JobId
+8: List Volumes to Restore All Files
+9: List Pool Attributes for a selected Pool
+10: List total files/bytes by Job
+11: List total files/bytes by Volume
+12: List Files for a selected JobId
+13: List Jobs stored on a selected MediaId
+14: List Jobs stored for a given Volume name
+15: List Volumes Bacula thinks are in changer
+16: List Volumes likely to need replacement from age or errors
+Choose a query (1-16):
+\end{verbatim}
+\normalsize
+
+\item [quit]
+ \index[general]{quit}
+ This command terminates the console program. The console program sends the
+ {\bf quit} request to the Director and waits for acknowledgment. If the
+ Director is busy doing a previous command for you that has not terminated, it
+ may take some time. You may quit immediately by issuing the {\bf .quit}
+ command (i.e. quit preceded by a period).
+
+\item [relabel]
+ \index[general]{relabel}
+ \index[general]{relabel}
+ This command is used to label physical volumes. The full form of this
+ command is:
+
+relabel storage=\lt{}storage-name\gt{} oldvolume=\lt{}old-volume-name\gt{}
+ volume=\lt{}newvolume-name\gt{}
+
+ If you leave out any part, you will be prompted for it. In order for
+ the Volume (old-volume-name) to be relabeled, it must be in the catalog,
+ and the volume status must be marked {\bf Purged} or {\bf Recycle}.
+ This happens automatically as a result of applying retention periods, or
+ you may explicitly purge the volume using the {\bf purge} command.
+
+ Once the volume is physically relabeled, the old data previously written
+ on the Volume is lost and cannot be recovered.
+
+\item [release]
+ \index[general]{release}
+ This command is used to cause the Storage daemon to rewind (release) the
+ current tape in the drive, and to re-read the Volume label the next time
+ the tape is used.
+
+release storage=\lt{}storage-name\gt{}
+
+ After a release command, the device is still kept open by Bacula (unless
+ Always Open is set to No in the Storage Daemon's configuration) so it
+ cannot be used by another program. However, with some tape drives, the
+ operator can remove the current tape and to insert a different one, and
+ when the next Job starts, Bacula will know to re-read the tape label to
+ find out what tape is mounted. If you want to be able to use the drive
+ with another program (e.g. {\bf mt}), you must use the {\bf unmount}
+ command to cause Bacula to completely release (close) the device.
+
+\item [reload]
+ \index[general]{reload}
+ The reload command causes the Director to re-read its configuration
+ file and apply the new values. The new values will take effect
+ immediately for all new jobs. However, if you change schedules,
+ be aware that the scheduler pre-schedules jobs up to two hours in
+ advance, so any changes that are to take place during the next two
+ hours may be delayed. Jobs that have already been scheduled to run
+ (i.e. surpassed their requested start time) will continue with the
+ old values. New jobs will use the new values. Each time you issue
+ a reload command while jobs are running, the prior config values
+ will queued until all jobs that were running before issuing
+ the reload terminate, at which time the old config values will
+ be released from memory. The Directory permits keeping up to
+ ten prior set of configurations before it will refuse a reload
+ command. Once at least one old set of config values has been
+ released it will again accept new reload commands.
+
+ While it is possible to reload the Director's configuration on the fly,
+ even while jobs are executing, this is a complex operation and not
+ without side effects. Accordingly, if you have to reload the Director's
+ configuration while Bacula is running, it is advisable to restart the
+ Director at the next convenient opportunity.
+
+\label{restore_command}
+\item [restore]
+ \index[general]{restore}
+ The restore command allows you to select one or more Jobs (JobIds) to be
+ restored using various methods. Once the JobIds are selected, the File
+ records for those Jobs are placed in an internal Bacula directory tree,
+ and the restore enters a file selection mode that allows you to
+ interactively walk up and down the file tree selecting individual files
+ to be restored. This mode is somewhat similar to the standard Unix {\bf
+ restore} program's interactive file selection mode.
+
+restore storage=\lt{}storage-name\gt{} client=\lt{}backup-client-name\gt{}
+ where=\lt{}path\gt{} pool=\lt{}pool-name\gt{} fileset=\lt{}fileset-name\gt{}
+ restoreclient=\lt{}restore-client-name\gt{}
+ select current all done
+
+ Where {\bf current}, if specified, tells the restore command to
+ automatically select a restore to the most current backup. If not
+ specified, you will be prompted. The {\bf all} specification tells the
+ restore command to restore all files. If it is not specified, you will
+ be prompted for the files to restore. For details of the {\bf restore}
+ command, please see the \ilink{Restore Chapter}{RestoreChapter} of this
+ manual.
+
+ The client keyword initially specifies the client from which the backup
+ was made and the client to which the restore will be make. However,
+ if the restoreclient keyword is specified, then the restore is written
+ to that client.
+
+\item [run]
+ \index[general]{run}
+ This command allows you to schedule jobs to be run immediately. The full form
+ of the command is:
+
+run job=\lt{}job-name\gt{} client=\lt{}client-name\gt{}
+ fileset=\lt{}FileSet-name\gt{} level=\lt{}level-keyword\gt{}
+ storage=\lt{}storage-name\gt{} where=\lt{}directory-prefix\gt{}
+ when=\lt{}universal-time-specification\gt{} spooldata=yes|no yes
+
+ Any information that is needed but not specified will be listed for
+ selection, and before starting the job, you will be prompted to accept,
+ reject, or modify the parameters of the job to be run, unless you have
+ specified {\bf yes}, in which case the job will be immediately sent to
+ the scheduler.
+
+ On my system, when I enter a run command, I get the following prompt:
+
+\footnotesize
+\begin{verbatim}
+A job name must be specified.
+The defined Job resources are:
+ 1: Matou
+ 2: Polymatou
+ 3: Rufus
+ 4: Minimatou
+ 5: Minou
+ 6: PmatouVerify
+ 7: MatouVerify
+ 8: RufusVerify
+ 9: Watchdog
+Select Job resource (1-9):
+
+\end{verbatim}
+\normalsize
+
+If I then select number 5, I am prompted with:
+
+\footnotesize
+\begin{verbatim}
+Run Backup job
+JobName: Minou
+FileSet: Minou Full Set
+Level: Incremental
+Client: Minou
+Storage: DLTDrive
+Pool: Default
+When: 2003-04-23 17:08:18
+OK to run? (yes/mod/no):
+
+\end{verbatim}
+\normalsize
+
+If I now enter {\bf yes}, the Job will be run. If I enter {\bf mod}, I will
+be presented with the following prompt.
+
+\footnotesize
+\begin{verbatim}
+Parameters to modify:
+ 1: Level
+ 2: Storage
+ 3: Job
+ 4: FileSet
+ 5: Client
+ 6: When
+ 7: Pool
+Select parameter to modify (1-7):
+
+\end{verbatim}
+\normalsize
+
+If you wish to start a job at a later time, you can do so by setting the When
+time. Use the {\bf mod} option and select {\bf When} (no. 6). Then enter the
+desired start time in YYYY-MM-DD HH:MM:SS format.
+
+The spooldata argument of the run command cannot be modified through the menu
+and is only accessible by setting its value on the intial command line. If
+no spooldata flag is set, the job, storage or schedule flag is used.
+
+\item [setdebug]
+ \index[general]{setdebug}
+ \index[general]{setdebug}
+ \index[general]{debugging}
+ \index[general]{debugging Win32}
+ \index[general]{Windows!debugging}
+ This command is used to set the debug level in each daemon. The form of this
+ command is:
+
+setdebug level=nn [trace=0/1 client=\lt{}client-name\gt{} | dir | director |
+ storage=\lt{}storage-name\gt{} | all]
+
+ If trace=1 is set, then tracing will be enabled, and the daemon will be
+ placed in trace mode, which means that all debug output as set by the
+ debug level will be directed to the file {\bf bacula.trace} in the
+ current directory of the daemon. Normally, tracing is needed only for
+ Win32 clients where the debug output cannot be written to a terminal or
+ redirected to a file. When tracing, each debug output message is
+ appended to the trace file. You must explicitly delete the file when
+ you are done.
+
+\item [setip]
+ \index[general]{setip}
+ Sets new client address -- if authorized.
+
+
+\item [show]
+ \index[general]{show}
+ \index[general]{show}
+ The show command will list the Director's resource records as defined in
+ the Director's configuration file (normally {\bf bacula-dir.conf}).
+ This command is used mainly for debugging purposes by developers.
+ The following keywords are accepted on the
+ show command line: catalogs, clients, counters, devices, directors,
+ filesets, jobs, messages, pools, schedules, storages, all, help.
+ Please don't confuse this command
+ with the {\bf list}, which displays the contents of the catalog.
+
+\item [sqlquery]
+ \index[general]{sqlquery}
+ The sqlquery command puts the Console program into SQL query mode where
+ each line you enter is concatenated to the previous line until a
+ semicolon (;) is seen. The semicolon terminates the command, which is
+ then passed directly to the SQL database engine. When the output from
+ the SQL engine is displayed, the formation of a new SQL command begins.
+ To terminate SQL query mode and return to the Console command prompt,
+ you enter a period (.) in column 1.
+
+ Using this command, you can query the SQL catalog database directly.
+ Note you should really know what you are doing otherwise you could
+ damage the catalog database. See the {\bf query} command below for
+ simpler and safer way of entering SQL queries.
+
+ Depending on what database engine you are using (MySQL, PostgreSQL or
+ SQLite), you will have somewhat different SQL commands available. For
+ more detailed information, please refer to the MySQL, PostgreSQL or
+ SQLite documentation.
+
+\item [status]
+ \index[general]{status}
+
+ This command will display the status of all components. For the director, it
+ will display the next jobs that are scheduled during the next 24 hours as
+ well as the status of currently running jobs. For the Storage Daemon, you
+ will have drive status or autochanger content. The File Daemon will give you
+ information about current jobs like average speed or file accounting. The
+ full form of this command is:
+
+status [all | dir=\lt{}dir-name\gt{} | director [days=nnn] |
+ client=\lt{}client-name\gt{} | [slots] storage=\lt{}storage-name\gt{}]
+
+ If you do a {\bf status dir}, the console will list any currently
+ running jobs, a summary of all jobs scheduled to be run in the next 24
+ hours, and a listing of the last ten terminated jobs with their statuses.
+ The scheduled jobs summary will include the Volume name to be used. You
+ should be aware of two things: 1. to obtain the volume name, the code
+ goes through the same code that will be used when the job runs, but it
+ does not do pruning nor recycling of Volumes; 2. The Volume listed is
+ at best a guess. The Volume actually used may be different because of
+ the time difference (more durations may expire when the job runs) and
+ another job could completely fill the Volume requiring a new one.
+
+ In the Running Jobs listing, you may find the following types of
+ information:
+
+
+\footnotesize
+\begin{verbatim}
+2507 Catalog MatouVerify.2004-03-13_05.05.02 is waiting execution
+5349 Full CatalogBackup.2004-03-13_01.10.00 is waiting for higher
+ priority jobs to finish
+5348 Differe Minou.2004-03-13_01.05.09 is waiting on max Storage jobs
+5343 Full Rufus.2004-03-13_01.05.04 is running
+\end{verbatim}
+\normalsize
+
+ Looking at the above listing from bottom to top, obviously JobId 5343
+ (Rufus) is running. JobId 5348 (Minou) is waiting for JobId 5343 to
+ finish because it is using the Storage resource, hence the "waiting on
+ max Storage jobs". JobId 5349 has a lower priority than all the other
+ jobs so it is waiting for higher priority jobs to finish, and finally,
+ JobId 2507 (MatouVerify) is waiting because only one job can run at a
+ time, hence it is simply "waiting execution"
+
+ If you do a {\bf status dir}, it will by default list the first
+ occurrence of all jobs that are scheduled today and tomorrow. If you
+ wish to see the jobs that are scheduled in the next three days (e.g. on
+ Friday you want to see the first occurrence of what tapes are scheduled
+ to be used on Friday, the weekend, and Monday), you can add the {\bf
+ days=3} option. Note, a {\bf days=0} shows the first occurrence of jobs
+ scheduled today only. If you have multiple run statements, the first
+ occurrence of each run statement for the job will be displayed for the
+ period specified.
+
+ If your job seems to be blocked, you can get a general idea of the
+ problem by doing a {\bf status dir}, but you can most often get a
+ much more specific indication of the problem by doing a
+ {\bf status storage=xxx}. For example, on an idle test system, when
+ I do {\bf status storage=File}, I get:
+\footnotesize

+\end{verbatim}
+\normalsize
+
+Now, what this tells me is that no jobs are running and that none of
+the devices are in use. Now, if I {\bf unmount} the autochanger, which
+will not be used in this example, and then start a Job that uses the
+File device, the job will block. When I re-issue the status storage
+command, I get for the Device status:
+
+\footnotesize
+\begin{verbatim}
+status storage=File
+...
+Device status:
+Autochanger "DDS-4-changer" with devices:

+Device "File" (/tmp) is not open.
+ Device is BLOCKED waiting for media.
+====
+...
+\end{verbatim}
+\normalsize
+
+Now, here it should be clear that if a job were running that wanted
+to use the Autochanger (with two devices), it would block because
+the user unmounted the device. The real problem for the Job I started
+using the "File" device is that the device is blocked waiting for
+media -- that is Bacula needs you to label a Volume.

+\item [umount]
+ \index[general]{umount}
+ For old-time Unix guys. See the unmount command for full details.
+
+\item [unmount]
+ \index[general]{unmount}
+ This command causes the indicated Bacula Storage daemon to unmount the
+ specified device. The forms of the command are the same as the mount command:
+\footnotesize
+\begin{verbatim}
+unmount storage=<storage-name> [ drive=<num> ]
+
+unmount [ jobid=<id> | job=<job-name> ]
+\end{verbatim}
+\normalsize
+
+ Once you unmount a storage device, Bacula will no longer be able to use
+ it until you issue a mount command for that device. If Bacula needs to
+ access that device, it will block and issue mount requests periodically
+ to the operator.
+
+ If the device you are unmounting is an autochanger, it will unload
+ the drive you have specified on the command line. If no drive is
+ specified, it will assume drive 1.

+ This command will update the catalog for either a specific Pool record, a Volume
+ record, or the Slots in an autochanger with barcode capability. In the case
+ of updating a Pool record, the new information will be automatically taken
+ from the corresponding Director's configuration resource record. It can be
+ used to increase the maximum number of volumes permitted or to set a maximum
+ number of volumes. The following main keywords may be specified:
+\footnotesize
+\begin{verbatim}
+ media, volume, pool, slots, stats
+\end{verbatim}
+\normalsize
+
+In the case of updating a Volume, you will be prompted for which value you
+wish to change. The following Volume parameters may be changed:
+
+\footnotesize
+\begin{verbatim}
+
+ Volume Status
+ Volume Retention Period
+ Volume Use Duration
+ Maximum Volume Jobs
+ Maximum Volume Files
+ Maximum Volume Bytes
+ Recycle Flag
+ Recycle Pool
+ Slot
+ InChanger Flag
+ Pool
+ Volume Files
+ Volume from Pool
+ All Volumes from Pool
+ All Volumes from all Pools
+
+\end{verbatim}
+\normalsize
+
+ For slots {\bf update slots}, Bacula will obtain a list of slots and
+ their barcodes from the Storage daemon, and for each barcode found, it
+ will automatically update the slot in the catalog Media record to
+ correspond to the new value. This is very useful if you have moved
+ cassettes in the magazine, or if you have removed the magazine and
+ inserted a different one. As the slot of each Volume is updated, the
+ InChanger flag for that Volume will also be set, and any other Volumes
+ in the Pool that were last mounted on the same Storage device
+ will have their InChanger flag turned off. This permits
+ Bacula to know what magazine (tape holder) is currently in the
+ autochanger.
+
+ If you do not have barcodes, you can accomplish the same thing in
+ version 1.33 and later by using the {\bf update slots scan} command.
+ The {\bf scan} keyword tells Bacula to physically mount each tape and to
+ read its VolumeName.
+
+ For Pool {\bf update pool}, Bacula will move the Volume record from its
+ existing pool to the pool specified.
+
+ For {\bf Volume from Pool}, {\bf All Volumes from Pool} and {\bf All Volumes
+ from all Pools}, the following values are updated from the Pool record:
+ Recycle, RecyclePool, VolRetention, VolUseDuration, MaxVolJobs, MaxVolFiles,
+ and MaxVolBytes. (RecyclePool feature is available with bacula 2.1.4 or
+ higher.)
+
+ The full form of the update command with all command line arguments is:
+
+\footnotesize
+\begin{verbatim}
+ update volume=xxx pool=yyy slots volstatus=xxx VolRetention=ddd
+ VolUse=ddd MaxVolJobs=nnn MaxVolBytes=nnn Recycle=yes|no
+ slot=nnn enabled=n recyclepool=zzz
+
+\end{verbatim}
+\normalsize
+
+\item [use]
+ \index[general]{use}
+ This command allows you to specify which Catalog database to use. Normally,
+you will be using only one database so this will be done automatically. In
+the case that you are using more than one database, you can use this command
+to switch from one to another.
+
+use \lt{}database-name\gt{}
+
+\item [var]
+ \label{var}
+ \index[general]{var name}
+ This command takes a string or quoted string and does variable expansion on
+ it the same way variable expansion is done on the {\bf LabelFormat} string.
+ Thus, for the most part, you can test your LabelFormat strings. The
+ difference between the {\bf var} command and the actual LabelFormat process
+ is that during the var command, no job is running so "dummy" values are
+ used in place of Job specific variables. Generally, however, you will get a
+ good idea of what is going to happen in the real case.
+
+\item [version]
+ \index[general]{version}
+ The command prints the Director's version.
+
+\item [wait]
+ \index[general]{wait}
+ The wait command causes the Director to pause until there are no jobs
+ running. This command is useful in a batch situation such as regression
+ testing where you wish to start a job and wait until that job completes
+ before continuing. This command now has the following options:
+\footnotesize
+\begin{verbatim}
+ wait [jobid=nn] [jobuid=unique id] [job=job name]
+\end{verbatim}
+\normalsize
+ If specified with a specific JobId, ... the wait command will wait
+ for that particular job to terminate before continuing.

+\index[general]{Special dot Commands}
+
+There is a list of commands that are prefixed with a period (.). These
+commands are intended to be used either by batch programs or graphical user
+interface front-ends. They are not normally used by interactive users. Once
+GUI development begins, this list will be considerably expanded. The following
+is the list of dot commands:
+
+\footnotesize
+\begin{verbatim}
+.backups job=xxx list backups for specified job
+.clients list all client names
+.defaults client=xxx fileset=yyy list defaults for specified client
+.die cause the Director to segment fault (for debugging)

+\section{Special At (@) Commands}
+\index[general]{Commands!Special At @}
+\index[general]{Special At (@) Commands}
+
+Normally, all commands entered to the Console program are immediately
+forwarded to the Director, which may be on another machine, to be executed.
+However, there is a small list of {\bf at} commands, all beginning with an at
+character (@), that will not be sent to the Director, but rather interpreted
+by the Console program directly. Note, these commands are implemented only in
+the tty console program and not in the GNOME Console. These commands are:
+
+\begin{description}
+
+\item [@input \lt{}filename\gt{}]
+ \index[general]{@input \lt{}filename\gt{}}
+ Read and execute the commands contained in the file specified.
+
+\item [@output \lt{}filename\gt{} w/a]
+ \index[general]{@output \lt{}filename\gt{} w/a}
+ Send all following output to the filename specified either overwriting the
+file (w) or appending to the file (a). To redirect the output to the
+terminal, simply enter {\bf @output} without a filename specification.
+WARNING: be careful not to overwrite a valid file. A typical example during a
+regression test might be:
+
+\footnotesize
+\begin{verbatim}
+ @output /dev/null
+ commands ...
+ @output
+
+\end{verbatim}
+\normalsize
+
+\item [@tee \lt{}filename\gt{} w/a]
+ \index[general]{@tee \lt{}filename\gt{} w/a}
+ Send all subsequent output to both the specified file and the terminal. It is
+ turned off by specifying {\bf @tee} or {\bf @output} without a filename.
+
+\item [@sleep \lt{}seconds\gt{}]
+ \index[general]{@sleep \lt{}seconds\gt{}}
+ Sleep the specified number of seconds.
+
+\item [@time]
+ \index[general]{@time}
+ Print the current time and date.
+
+\item [@version]
+ \index[general]{@version}
+ Print the console's version.
+
+\item [@quit]
+ \index[general]{@quit}
+ quit
+
+\item [@exit]
+ \index[general]{@exit}
+ quit
+
+\item [@\# anything]
+ \index[general]{anything}
+ Comment
+
+\item [@separator \lt{}char\gt{}]
+\index[general]{@separator}
+ When using bconsole with readline, you can set the command separator to one
+ of those characters to write commands who require multiple input on one line,
+ or to put multiple commands on a single line.
+\begin{verbatim}
+ !$%&'()*+,-/:;<>?[]^`{|}~
+\end{verbatim}
+
+ Note, if you use a semicolon (;) as a separator character, which is
+ common, you will not be able to use the {\bf sql} command, which
+ requires each command to be terminated by a semicolon.
+
+\end{description}
+
+\label{scripting}
+\section{Running the Console from a Shell Script}
+\index[general]{Script!Running the Console Program from a Shell}
+\index[general]{Running the Console Program from a Shell Script}
+
+You can automate many Console tasks by running the console program from a
+shell script. For example, if you have created a file containing the following
+commands:
+
+\footnotesize
+\begin{verbatim}
+ ./bconsole -c ./bconsole.conf <<END_OF_DATA
+ unmount storage=DDS-4
+ quit
+ END_OF_DATA
+\end{verbatim}
+\normalsize
+
+when that file is executed, it will unmount the current DDS-4 storage device.
+You might want to run this command during a Job by using the {\bf
+RunBeforeJob} or {\bf RunAfterJob} records.
+
+It is also possible to run the Console program from file input where the file
+contains the commands as follows:
+
+\footnotesize
+\begin{verbatim}
+./bconsole -c ./bconsole.conf <filename
+\end{verbatim}
+\normalsize
+
+where the file named {\bf filename} contains any set of console commands.
+
+As a real example, the following script is part of the Bacula regression
+tests. It labels a volume (a disk volume), runs a backup, then does a restore
+of the files saved.
+
+\footnotesize
+\begin{verbatim}
+bin/bconsole -c bin/bconsole.conf <<END_OF_DATA
+@output /dev/null
+messages
+@output /tmp/log1.out
+label volume=TestVolume001
+run job=Client1 yes
+wait
+messages
+@#
+@# now do a restore
+@#
+@output /tmp/log2.out
+restore current all
+yes
+wait
+messages
+@output
+quit
+END_OF_DATA
+\end{verbatim}
+\normalsize
+
+The output from the backup is directed to /tmp/log1.out and the output from
+the restore is directed to /tmp/log2.out. To ensure that the backup and
+restore ran correctly, the output files are checked with:
+
+\footnotesize
+\begin{verbatim}
+grep "^Termination: *Backup OK" /tmp/log1.out
+backupstat=$?
+grep "^Termination: *Restore OK" /tmp/log2.out
+restorestat=$?
+\end{verbatim}
+\normalsize
+
+\section{Adding Volumes to a Pool}
+\index[general]{Adding Volumes to a Pool}
+\index[general]{Pool!Adding Volumes to a}
+
+If you have used the {\bf label} command to label a Volume, it will be
+automatically added to the Pool, and you will not need to add any media to the
+pool.
+
+Alternatively, you may choose to add a number of Volumes to the pool without
+labeling them. At a later time when the Volume is requested by {\bf Bacula}
+you will need to label it.
+
+Before adding a volume, you must know the following information:
+
+\begin{enumerate}
+\item The name of the Pool (normally "Default")
+\item The Media Type as specified in the Storage Resource in the Director's
+ configuration file (e.g. "DLT8000")
+\item The number and names of the Volumes you wish to create.
+\end{enumerate}
+
+For example, to add media to a Pool, you would issue the following commands to
+the console program:
+
+\footnotesize
+\begin{verbatim}
+*add
+Enter name of Pool to add Volumes to: Default
+Enter the Media Type: DLT8000
+Enter number of Media volumes to create. Max=1000: 10
+Enter base volume name: Save
+Enter the starting number: 1
+10 Volumes created in pool Default
+*
+\end{verbatim}
+\normalsize
+
+To see what you have added, enter:
+
+\footnotesize
+\begin{verbatim}
+*list media pool=Default
++-------+----------+---------+---------+-------+------------------+
+| MedId | VolumeNa | MediaTyp| VolStat | Bytes | LastWritten |
++-------+----------+---------+---------+-------+------------------+
+| 11 | Save0001 | DLT8000 | Append | 0 | 0000-00-00 00:00 |
+| 12 | Save0002 | DLT8000 | Append | 0 | 0000-00-00 00:00 |
+| 13 | Save0003 | DLT8000 | Append | 0 | 0000-00-00 00:00 |
+| 14 | Save0004 | DLT8000 | Append | 0 | 0000-00-00 00:00 |
+| 15 | Save0005 | DLT8000 | Append | 0 | 0000-00-00 00:00 |
+| 16 | Save0006 | DLT8000 | Append | 0 | 0000-00-00 00:00 |
+| 17 | Save0007 | DLT8000 | Append | 0 | 0000-00-00 00:00 |
+| 18 | Save0008 | DLT8000 | Append | 0 | 0000-00-00 00:00 |
+| 19 | Save0009 | DLT8000 | Append | 0 | 0000-00-00 00:00 |
+| 20 | Save0010 | DLT8000 | Append | 0 | 0000-00-00 00:00 |
++-------+----------+---------+---------+-------+------------------+
+*
+\end{verbatim}
+\normalsize
+
+Notice that the console program automatically appended a number to the base
+Volume name that you specify (Save in this case). If you don't want it to
+append a number, you can simply answer 0 (zero) to the question "Enter number
+of Media volumes to create. Max=1000:", and in this case, it will create a
+single Volume with the exact name you specify.

+publishers or authors of the Document to the Document's overall subject
+(or to related matters) and contains nothing that could fall directly
+within that overall subject. (Thus, if the Document is in part a
+textbook of mathematics, a Secondary Section may not explain any
+mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The \textbf{"Invariant Sections"} are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License. If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant. The Document may contain zero
+Invariant Sections. If the Document does not identify any Invariant
+Sections then there are none.
+
+The \textbf{"Cover Texts"} are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License. A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A \textbf{"Transparent"} copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text. A copy that is not "Transparent" is called \textbf{"Opaque"}.
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input format, SGML
+or XML using a publicly available DTD, and standard-conforming simple
+HTML, PostScript or PDF designed for human modification. Examples of
+transparent image formats include PNG, XCF and JPG. Opaque formats
+include proprietary formats that can be read and edited only by
+proprietary word processors, SGML or XML for which the DTD and/or
+processing tools are not generally available, and the
+machine-generated HTML, PostScript or PDF produced by some word
+processors for output purposes only.
+
+The \textbf{"Title Page"} means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, "Title Page" means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+A section \textbf{"Entitled XYZ"} means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language. (Here XYZ stands for a
+specific section name mentioned below, such as \textbf{"Acknowledgements"},
+\textbf{"Dedications"}, \textbf{"Endorsements"}, or \textbf{"History"}.)
+To \textbf{"Preserve the Title"}
+of such a section when you modify the Document means that it remains a
+section "Entitled XYZ" according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document. These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+
+\begin{center}
+{\Large\bf 2. VERBATIM COPYING}
+\end{center}
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+
+\begin{center}
+{\Large\bf 3. COPYING IN QUANTITY}
+\end{center}
+
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+
+\begin{center}
+{\Large\bf 4. MODIFICATIONS}
+\end{center}
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+\begin{itemize}
+\item[A.]
+ Use in the Title Page (and on the covers, if any) a title distinct
+ from that of the Document, and from those of previous versions
+ (which should, if there were any, be listed in the History section
+ of the Document). You may use the same title as a previous version
+ if the original publisher of that version gives permission.
+
+\item[B.]
+ List on the Title Page, as authors, one or more persons or entities
+ responsible for authorship of the modifications in the Modified
+ Version, together with at least five of the principal authors of the
+ Document (all of its principal authors, if it has fewer than five),
+ unless they release you from this requirement.
+
+\item[C.]
+ State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+
+\item[D.]
+ Preserve all the copyright notices of the Document.
+
+\item[E.]
+ Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+
+\item[F.]
+ Include, immediately after the copyright notices, a license notice
+ giving the public permission to use the Modified Version under the
+ terms of this License, in the form shown in the Addendum below.
+
+\item[G.]
+ Preserve in that license notice the full lists of Invariant Sections
+ and required Cover Texts given in the Document's license notice.
+
+\item[H.]
+ Include an unaltered copy of this License.
+
+\item[I.]
+ Preserve the section Entitled "History", Preserve its Title, and add
+ to it an item stating at least the title, year, new authors, and
+ publisher of the Modified Version as given on the Title Page. If
+ there is no section Entitled "History" in the Document, create one
+ stating the title, year, authors, and publisher of the Document as
+ given on its Title Page, then add an item describing the Modified
+ Version as stated in the previous sentence.
+
+\item[J.]
+ Preserve the network location, if any, given in the Document for
+ public access to a Transparent copy of the Document, and likewise
+ the network locations given in the Document for previous versions
+ it was based on. These may be placed in the "History" section.
+ You may omit a network location for a work that was published at
+ least four years before the Document itself, or if the original
+ publisher of the version it refers to gives permission.
+
+\item[K.]
+ For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the section all
+ the substance and tone of each of the contributor acknowledgements
+ and/or dedications given therein.
+
+\item[L.]
+ Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section titles.
+
+\item[M.]
+ Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+
+\item[N.]
+ Do not retitle any existing section to be Entitled "Endorsements"
+ or to conflict in title with any Invariant Section.
+
+\item[O.]
+ Preserve any Warranty Disclaimers.
+\end{itemize}
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled "Endorsements", provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+
+\begin{center}
+{\Large\bf 5. COMBINING DOCUMENTS}
+\end{center}
+
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled "History"
+in the various original documents, forming one section Entitled
+"History"; likewise combine any sections Entitled "Acknowledgements",
+and any sections Entitled "Dedications". You must delete all sections
+Entitled "Endorsements".
+
+\begin{center}
+{\Large\bf 6. COLLECTIONS OF DOCUMENTS}
+\end{center}
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+
+\begin{center}
+{\Large\bf 7. AGGREGATION WITH INDEPENDENT WORKS}
+\end{center}
+
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an "aggregate" if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+
+\begin{center}
+{\Large\bf 8. TRANSLATION}
+\end{center}
+
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers. In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled "Acknowledgements",
+"Dedications", or "History", the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+
+\begin{center}
+{\Large\bf 9. TERMINATION}
+\end{center}
+
+
+You may not copy, modify, sublicense, or distribute the Document except
+as expressly provided for under this License. Any other attempt to
+copy, modify, sublicense or distribute the Document is void, and will
+automatically terminate your rights under this License. However,
+parties who have received copies, or rights, from you under this
+License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+
+\begin{center}
+{\Large\bf 10. FUTURE REVISIONS OF THIS LICENSE}
+\end{center}
+
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns. See
+http://www.gnu.org/copyleft/.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation. If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.
+
+
+\begin{center}
+{\Large\bf ADDENDUM: How to use this License for your documents}
+% TODO: this is too long for table of contents
+\end{center}
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+\bigskip
+\begin{quote}
+ Copyright \copyright YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.2
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
+ A copy of the license is included in the section entitled "GNU
+ Free Documentation License".
+\end{quote}
+\bigskip
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the "with...Texts." line with this:
+
+\bigskip
+\begin{quote}
+ with the Invariant Sections being LIST THEIR TITLES, with the
+ Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
+\end{quote}
+\bigskip
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

+# \usepackage{makeidx}
+# \makeindex
+# \index{entry1}
+# \index{entry2}
+# \index{entry3}

+# --- MULTIPLE INDICES ---
+#
+# \usepackage{makeidx}
+# \usepackage{index}
+# \makeindex -- latex2html doesn't care but LaTeX does.
+# \newindex{ref1}{ext1}{ext2}{title1}
+# \newindex{ref2}{ext1}{ext2}{title2}
+# \newindex{ref3}{ext1}{ext2}{title3}

+# ___________________
+#
+# For the multiple-index style, each index is identified by the ref argument to \newindex, \index,
+# and \printindex. A default index is allowed, which is indicated by omitting the optional
+# argument. The default index does not require a \newindex command. As \index commands
+# are encountered, their entries are stored according
+# to the ref argument. When the \printindex command is encountered, the stored index
+# entries for that argument are retrieved and printed. The title for each index is taken
+# from the last argument in the \newindex command.
+# While processing \index and \printindex commands, if no argument is given the index entries
+# are built into a default index. The title of the default index is simply "Index".
+# This makes the difference between single- and multiple-index processing trivial.
+#
+# Another method can be used by omitting the \printindex command and just using \include to
+# pull in index files created by the makeindex program. These files will start with
+# \begin{theindex}. This command is used to determine where to print the index. Using this
+# approach, the indices will be output in the same order as the newindex commands were
+# originally found (see below). Using a combination of \printindex and \include{indexfile} has not
+# been tested and may produce undesireable results.
+#
+# The index data are stored in a hash for later sorting and output. As \printindex
+# commands are handled, the order in which they were found in the tex filea is saved,
+# associated with the ref argument to \printindex.
+#
+# We use the original %index hash to store the index data into. We append a \002 followed by the
+# name of the index to isolate the entries in different indices from each other. This is necessary
+# so that different indices can have entries with the same name. For the default index, the \002 is
+# appended without the name.
+#
+# Since the index order in the output cannot be determined if the \include{indexfile}
+# command is used, the order will be assumed from the order in which the \newindex
+# commands were originally seen in the TeX files. This order is saved as well as the
+# order determined from any printindex{ref} commands. If \printindex commnads are used
+# to specify the index output, that order will be used. If the \include{idxfile} command
+# is used, the order of the original newindex commands will be used. In this case the
+# default index will be printed last since it doesn't have a corresponding \newindex
+# command and its order cannot be determined. Mixing \printindex and \include{idxfile}
+# commands in the same file is likely to produce less than satisfactory results.
+#
+#
+# The hash containing index data is named %indices. It contains the following data:
+#{
+# 'title' => {
+# $ref1 => $indextitle ,
+# $ref2 => $indextitle ,
+# ...

+
+\section{General}
+\index[general]{General }
+\addcontentsline{toc}{subsection}{General}
+
+This chapter is intended to be a technical discussion of the Catalog services
+and as such is not targeted at end users but rather at developers and system
+administrators that want or need to know more of the working details of {\bf
+Bacula}.
+
+The {\bf Bacula Catalog} services consist of the programs that provide the SQL
+database engine for storage and retrieval of all information concerning files
+that were backed up and their locations on the storage media.
+
+We have investigated the possibility of using the following SQL engines for
+Bacula: Beagle, mSQL, GNU SQL, PostgreSQL, SQLite, Oracle, and MySQL. Each
+presents certain problems with either licensing or maturity. At present, we
+have chosen for development purposes to use MySQL, PostgreSQL and SQLite.
+MySQL was chosen because it is fast, proven to be reliable, widely used, and
+actively being developed. MySQL is released under the GNU GPL license.
+PostgreSQL was chosen because it is a full-featured, very mature database, and
+because Dan Langille did the Bacula driver for it. PostgreSQL is distributed
+under the BSD license. SQLite was chosen because it is small, efficient, and
+can be directly embedded in {\bf Bacula} thus requiring much less effort from
+the system administrator or person building {\bf Bacula}. In our testing
+SQLite has performed very well, and for the functions that we use, it has
+never encountered any errors except that it does not appear to handle
+databases larger than 2GBytes. That said, we would not recommend it for
+serious production use.
+
+The Bacula SQL code has been written in a manner that will allow it to be
+easily modified to support any of the current SQL database systems on the
+market (for example: mSQL, iODBC, unixODBC, Solid, OpenLink ODBC, EasySoft
+ODBC, InterBase, Oracle8, Oracle7, and DB2).
+
+If you do not specify either {\bf \verb{--{with-mysql} or {\bf \verb{--{with-postgresql} or
+{\bf \verb{--{with-sqlite} on the ./configure line, Bacula will use its minimalist
+internal database. This database is kept for build reasons but is no longer
+supported. Bacula {\bf requires} one of the three databases (MySQL,
+PostgreSQL, or SQLite) to run.
+
+\subsection{Filenames and Maximum Filename Length}
+\index[general]{Filenames and Maximum Filename Length }
+\index[general]{Length!Filenames and Maximum Filename }
+\addcontentsline{toc}{subsubsection}{Filenames and Maximum Filename Length}
+
+In general, either MySQL, PostgreSQL or SQLite permit storing arbitrary long
+path names and file names in the catalog database. In practice, there still
+may be one or two places in the Catalog interface code that restrict the
+maximum path length to 512 characters and the maximum file name length to 512
+characters. These restrictions are believed to have been removed. Please note,
+these restrictions apply only to the Catalog database and thus to your ability
+to list online the files saved during any job. All information received and
+stored by the Storage daemon (normally on tape) allows and handles arbitrarily
+long path and filenames.

+
+\subsection{Database Table Design}
+\index[general]{Design!Database Table }
+\index[general]{Database Table Design }
+\addcontentsline{toc}{subsubsection}{Database Table Design}
+
+All discussions that follow pertain to the MySQL database. The details for the
+PostgreSQL and SQLite databases are essentially identical except for that all
+fields in the SQLite database are stored as ASCII text and some of the
+database creation statements are a bit different. The details of the internal
+Bacula catalog are not discussed here.
+
+Because the Catalog database may contain very large amounts of data for large
+sites, we have made a modest attempt to normalize the data tables to reduce
+redundant information. While reducing the size of the database significantly,
+it does, unfortunately, add some complications to the structures.
+
+In simple terms, the Catalog database must contain a record of all Jobs run by
+Bacula, and for each Job, it must maintain a list of all files saved, with
+their File Attributes (permissions, create date, ...), and the location and
+Media on which the file is stored. This is seemingly a simple task, but it
+represents a huge amount interlinked data. Note: the list of files and their
+attributes is not maintained when using the internal Bacula database. The data
+stored in the File records, which allows the user or administrator to obtain a
+list of all files backed up during a job, is by far the largest volume of
+information put into the Catalog database.
+
+Although the Catalog database has been designed to handle backup data for
+multiple clients, some users may want to maintain multiple databases, one for
+each machine to be backed up. This reduces the risk of confusion of accidental
+restoring a file to the wrong machine as well as reducing the amount of data
+in a single database, thus increasing efficiency and reducing the impact of a
+lost or damaged database.
+
+\section{Sequence of Creation of Records for a Save Job}
+\index[general]{Sequence of Creation of Records for a Save Job }
+\index[general]{Job!Sequence of Creation of Records for a Save }
+\addcontentsline{toc}{subsection}{Sequence of Creation of Records for a Save
+Job}
+
+Start with StartDate, ClientName, Filename, Path, Attributes, MediaName,
+MediaCoordinates. (PartNumber, NumParts). In the steps below, ``Create new''
+means to create a new record whether or not it is unique. ``Create unique''
+means each record in the database should be unique. Thus, one must first
+search to see if the record exists, and only if not should a new one be
+created, otherwise the existing RecordId should be used.
+
+\begin{enumerate}
+\item Create new Job record with StartDate; save JobId

+\end{longtable}
+
+The {\bf Filename} table shown above contains the name of each file backed up
+with the path removed. If different directories or machines contain the same
+filename, only one copy will be saved in this table.

+ \hline
+{Path } & {Blob } & {Full Path }
+\\ \hline
+
+\end{longtable}
+
+The {\bf Path} table contains shown above the path or directory names of all
+directories on the system or systems. The filename and any MSDOS disk name are
+stripped off. As with the filename, only one copy of each directory name is
+kept regardless of how many machines or drives have the same directory. These
+path names should be stored in Unix path name format.
+
+Some simple testing on a Linux file system indicates that separating the
+filename and the path may be more complication than is warranted by the space
+savings. For example, this system has a total of 89,097 files, 60,467 of which
+have unique filenames, and there are 4,374 unique paths.
+
+Finding all those files and doing two stats() per file takes an average wall
+clock time of 1 min 35 seconds on a 400MHz machine running RedHat 6.1 Linux.
+
+Finding all those files and putting them directly into a MySQL database with
+the path and filename defined as TEXT, which is variable length up to 65,535
+characters takes 19 mins 31 seconds and creates a 27.6 MByte database.
+
+Doing the same thing, but inserting them into Blob fields with the filename
+indexed on the first 30 characters and the path name indexed on the 255 (max)
+characters takes 5 mins 18 seconds and creates a 5.24 MB database. Rerunning
+the job (with the database already created) takes about 2 mins 50 seconds.
+
+Running the same as the last one (Path and Filename Blob), but Filename
+indexed on the first 30 characters and the Path on the first 50 characters
+(linear search done there after) takes 5 mins on the average and creates a 3.4
+MB database. Rerunning with the data already in the DB takes 3 mins 35
+seconds.
+
+Finally, saving only the full path name rather than splitting the path and the
+file, and indexing it on the first 50 characters takes 6 mins 43 seconds and
+creates a 7.35 MB database.

+
+The {\bf File} table shown above contains one entry for each file backed up by
+Bacula. Thus a file that is backed up multiple times (as is normal) will have
+multiple entries in the File table. This will probably be the table with the
+most number of records. Consequently, it is essential to keep the size of this
+record to an absolute minimum. At the same time, this table must contain all
+the information (or pointers to the information) about the file and where it
+is backed up. Since a file may be backed up many times without having changed,
+the path and filename are stored in separate tables.
+
+This table contains by far the largest amount of information in the Catalog
+database, both from the stand point of number of records, and the stand point
+of total database size. As a consequence, the user must take care to
+periodically reduce the number of File records using the {\bf retention}
+command in the Console program.

+\end{longtable}
+
+The {\bf Job} table contains one record for each Job run by Bacula. Thus
+normally, there will be one per day per machine added to the database. Note,
+the JobId is used to index Job records in the database, and it often is shown
+to the user in the Console program. However, care must be taken with its use
+as it is not unique from database to database. For example, the user may have
+a database for Client data saved on machine Rufus and another database for
+Client data saved on machine Roxie. In this case, the two database will each
+have JobIds that match those in another database. For a unique reference to a
+Job, see Job below.
+
+The Name field of the Job record corresponds to the Name resource record given
+in the Director's configuration file. Thus it is a generic name, and it will
+be normal to find many Jobs (or even all Jobs) with the same Name.
+
+The Job field contains a combination of the Name and the schedule time of the
+Job by the Director. Thus for a given Director, even with multiple Catalog
+databases, the Job will contain a unique name that represents the Job.
+
+For a given Storage daemon, the VolSessionId and VolSessionTime form a unique
+identification of the Job. This will be the case even if multiple Directors
+are using the same Storage daemon.
+
+The Job Type (or simply Type) can have one of the following values:
+

+\end{longtable}
+
+The {\bf FileSet} table contains one entry for each FileSet that is used. The
+MD5 signature is kept to ensure that if the user changes anything inside the
+FileSet, it will be detected and the new FileSet will be used. This is
+particularly important when doing an incremental update. If the user deletes a
+file or adds a file, we need to ensure that a Full backup is done prior to the
+next incremental.

+
+\end{longtable}
+
+The {\bf JobMedia} table contains one entry at the following: start of
+the job, start of each new tape file, start of each new tape, end of the
+job. Since by default, a new tape file is written every 2GB, in general,
+you will have more than 2 JobMedia records per Job. The number can be
+varied by changing the "Maximum File Size" specified in the Device
+resource. This record allows Bacula to efficiently position close to
+(within 2GB) any given file in a backup. For restoring a full Job,
+these records are not very important, but if you want to retrieve
+a single file that was written near the end of a 100GB backup, the
+JobMedia records can speed it up by orders of magnitude by permitting
+forward spacing files and blocks rather than reading the whole 100GB
+backup.

+\section{General}
+\index{General }
+\addcontentsline{toc}{subsection}{General}
+
+This document describes the protocols used between the various daemons. As
+Bacula has developed, it has become quite out of date. The general idea still
+holds true, but the details of the fields for each command, and indeed the
+commands themselves have changed considerably.
+
+It is intended to be a technical discussion of the general daemon protocols
+and as such is not targeted at end users but rather at developers and system
+administrators that want or need to know more of the working details of {\bf
+Bacula}.
+
+\section{Low Level Network Protocol}
+\index{Protocol!Low Level Network }
+\index{Low Level Network Protocol }
+\addcontentsline{toc}{subsection}{Low Level Network Protocol}
+
+At the lowest level, the network protocol is handled by {\bf BSOCK} packets
+which contain a lot of information about the status of the network connection:
+who is at the other end, etc. Each basic {\bf Bacula} network read or write
+actually consists of two low level network read/writes. The first write always
+sends four bytes of data in machine independent byte order. If data is to
+follow, the first four bytes are a positive non-zero integer indicating the
+length of the data that follow in the subsequent write. If the four byte
+integer is zero or negative, it indicates a special request, a sort of network
+signaling capability. In this case, no data packet will follow. The low level
+BSOCK routines expect that only a single thread is accessing the socket at a
+time. It is advised that multiple threads do not read/write the same socket.
+If you must do this, you must provide some sort of locking mechanism. It would
+not be appropriate for efficiency reasons to make every call to the BSOCK
+routines lock and unlock the packet.
+
+\section{General Daemon Protocol}
+\index{General Daemon Protocol }
+\index{Protocol!General Daemon }
+\addcontentsline{toc}{subsection}{General Daemon Protocol}
+
+In general, all the daemons follow the following global rules. There may be
+exceptions depending on the specific case. Normally, one daemon will be
+sending commands to another daemon (specifically, the Director to the Storage
+daemon and the Director to the File daemon).
+
+\begin{itemize}
+\item Commands are always ASCII commands that are upper/lower case dependent
+ as well as space sensitive.
+\item All binary data is converted into ASCII (either with printf statements
+ or using base64 encoding).
+\item All responses to commands sent are always prefixed with a return
+ numeric code where codes in the 1000's are reserved for the Director, the
+ 2000's are reserved for the File daemon, and the 3000's are reserved for the
+Storage daemon.
+\item Any response that is not prefixed with a numeric code is a command (or
+ subcommand if you like) coming from the other end. For example, while the
+ Director is corresponding with the Storage daemon, the Storage daemon can
+request Catalog services from the Director. This convention permits each side
+to send commands to the other daemon while simultaneously responding to
+commands.
+\item Any response that is of zero length, depending on the context, either
+ terminates the data stream being sent or terminates command mode prior to
+ closing the connection.
+\item Any response that is of negative length is a special sign that normally
+ requires a response. For example, during data transfer from the File daemon
+ to the Storage daemon, normally the File daemon sends continuously without
+intervening reads. However, periodically, the File daemon will send a packet
+of length -1 indicating that the current data stream is complete and that the
+Storage daemon should respond to the packet with an OK, ABORT JOB, PAUSE,
+etc. This permits the File daemon to efficiently send data while at the same
+time occasionally ``polling'' the Storage daemon for his status or any
+special requests.
+
+Currently, these negative lengths are specific to the daemon, but shortly,
+the range 0 to -999 will be standard daemon wide signals, while -1000 to
+-1999 will be for Director user, -2000 to -2999 for the File daemon, and
+-3000 to -3999 for the Storage daemon.
+\end{itemize}

+\index{Protocol Used Between the Director and the Storage Daemon }
+\addcontentsline{toc}{subsection}{Protocol Used Between the Director and the
+Storage Daemon}
+
+Before sending commands to the File daemon, the Director opens a Message
+channel with the Storage daemon, identifies itself and presents its password.
+If the password check is OK, the Storage daemon accepts the Director. The
+Director then passes the Storage daemon, the JobId to be run as well as the
+File daemon authorization (append, read all, or read for a specific session).
+The Storage daemon will then pass back to the Director a enabling key for this
+JobId that must be presented by the File daemon when opening the job. Until
+this process is complete, the Storage daemon is not available for use by File
+daemons.
+
+\footnotesize
+\begin{verbatim}
+SD: listens
+DR: makes connection
+DR: Hello <Director-name> calling <password>
+SD: 3000 OK Hello
+DR: JobId=nnn Allow=(append, read) Session=(*, SessionId)
+ (Session not implemented yet)
+SD: 3000 OK Job Authorization=<password>
+DR: use device=<device-name> media_type=<media-type>
+ pool_name=<pool-name> pool_type=<pool_type>
+SD: 3000 OK use device
+\end{verbatim}
+\normalsize
+
+For the Director to be authorized, the \lt{}Director-name\gt{} and the
+\lt{}password\gt{} must match the values in one of the Storage daemon's
+Director resources (there may be several Directors that can access a single
+Storage daemon).

+DR: JobId=nnn Authorization=<password>

+ e.g.
+ 3000 OK Volumes = <number of volumes>
+ 3001 Volume = <volume-id> <start file> <start block>
+ <end file> <end block> <volume session-id>
+ 3002 Volume data = <date/time of last write> <Number bytes written>

+
+Command and control information is exchanged in human readable ASCII commands.
+
+
+\footnotesize
+\begin{verbatim}
+FD: listens
+SD: makes connection
+FD: append open session = <JobId> [<password>]
+SD: 3000 OK ticket = <number>
+FD: append data <ticket-number>
+SD: 3000 OK data address = <IPaddress> port = <port>
+\end{verbatim}
+\normalsize
+
+\subsection{Data Information}
+\index{Information!Data }
+\index{Data Information }
+\addcontentsline{toc}{subsubsection}{Data Information}
+
+The Data information consists of the file attributes and data to the Storage
+daemon. For the most part, the data information is sent one way: from the File
+daemon to the Storage daemon. This allows the File daemon to transfer
+information as fast as possible without a lot of handshaking and network
+overhead.
+
+However, from time to time, the File daemon needs to do a sort of checkpoint
+of the situation to ensure that everything is going well with the Storage
+daemon. To do so, the File daemon sends a packet with a negative length
+indicating that he wishes the Storage daemon to respond by sending a packet of
+information to the File daemon. The File daemon then waits to receive a packet
+from the Storage daemon before continuing.
+
+All data sent are in binary format except for the header packet, which is in
+ASCII. There are two packet types used data transfer mode: a header packet,
+the contents of which are known to the Storage daemon, and a data packet, the
+contents of which are never examined by the Storage daemon.
+
+The first data packet to the Storage daemon will be an ASCII header packet
+consisting of the following data.
+
+\lt{}File-Index\gt{} \lt{}Stream-Id\gt{} \lt{}Info\gt{} where {\bf
+\lt{}File-Index\gt{}} is a sequential number beginning from one that
+increments with each file (or directory) sent.
+
+where {\bf \lt{}Stream-Id\gt{}} will be 1 for the Attributes record and 2 for
+uncompressed File data. 3 is reserved for the MD5 signature for the file.
+
+where {\bf \lt{}Info\gt{}} transmit information about the Stream to the
+Storage Daemon. It is a character string field where each character has a
+meaning. The only character currently defined is 0 (zero), which is simply a
+place holder (a no op). In the future, there may be codes indicating
+compressed data, encrypted data, etc.
+
+Immediately following the header packet, the Storage daemon will expect any
+number of data packets. The series of data packets is terminated by a zero
+length packet, which indicates to the Storage daemon that the next packet will
+be another header packet. As previously mentioned, a negative length packet is
+a request for the Storage daemon to temporarily enter command mode and send a
+reply to the File daemon. Thus an actual conversation might contain the
+following exchanges:
+
+\footnotesize
+\begin{verbatim}
+FD: <1 1 0> (header packet)
+FD: <data packet containing file-attributes>
+FD: Null packet
+FD: <1 2 0>
+FD: <multiple data packets containing the file data>
+FD: Packet length = -1
+SD: 3000 OK
+FD: <2 1 0>
+FD: <data packet containing file-attributes>
+FD: Null packet
+FD: <2 2 0>
+FD: <multiple data packets containing the file data>
+FD: Null packet
+FD: Null packet
+FD: append end session <ticket-number>
+SD: 3000 OK end
+FD: append close session <ticket-number>
+SD: 3000 OK Volumes = <number of volumes>
+SD: 3001 Volume = <volumeid> <start file> <start block>
+ <end file> <end block> <volume session-id>
+SD: 3002 Volume data = <date/time of last write> <Number bytes written>
+ <number errors>
+SD: ... additional Volume / Volume data pairs for
+ volumes 2 .. n
+FD: close socket
+\end{verbatim}
+\normalsize
+
+The information returned to the File daemon by the Storage daemon in response
+to the {\bf append close session} is transmit in turn to the Director.

+\begin{center}
+{\bf\large Preamble}
+\end{center}
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document "free" in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of "copyleft", which means that derivative
+works of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does. But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book. We recommend this License
+principally for works whose purpose is instruction or reference.
+
+
+\begin{center}
+{\Large\bf 1. APPLICABILITY AND DEFINITIONS}
+\addcontentsline{toc}{section}{1. APPLICABILITY AND DEFINITIONS}
+\end{center}
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License. Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein. The \textbf{"Document"}, below,
+refers to any such manual or work. Any member of the public is a
+licensee, and is addressed as \textbf{"you"}. You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A \textbf{"Modified Version"} of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A \textbf{"Secondary Section"} is a named appendix or a front-matter section of
+the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall subject
+(or to related matters) and contains nothing that could fall directly
+within that overall subject. (Thus, if the Document is in part a
+textbook of mathematics, a Secondary Section may not explain any
+mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The \textbf{"Invariant Sections"} are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License. If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant. The Document may contain zero
+Invariant Sections. If the Document does not identify any Invariant
+Sections then there are none.
+
+The \textbf{"Cover Texts"} are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License. A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A \textbf{"Transparent"} copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text. A copy that is not "Transparent" is called \textbf{"Opaque"}.
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input format, SGML
+or XML using a publicly available DTD, and standard-conforming simple
+HTML, PostScript or PDF designed for human modification. Examples of
+transparent image formats include PNG, XCF and JPG. Opaque formats
+include proprietary formats that can be read and edited only by
+proprietary word processors, SGML or XML for which the DTD and/or
+processing tools are not generally available, and the
+machine-generated HTML, PostScript or PDF produced by some word
+processors for output purposes only.
+
+The \textbf{"Title Page"} means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, "Title Page" means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+A section \textbf{"Entitled XYZ"} means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language. (Here XYZ stands for a
+specific section name mentioned below, such as \textbf{"Acknowledgements"},
+\textbf{"Dedications"}, \textbf{"Endorsements"}, or \textbf{"History"}.)
+To \textbf{"Preserve the Title"}
+of such a section when you modify the Document means that it remains a
+section "Entitled XYZ" according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document. These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+

+\begin{center}
+{\Large\bf 2. VERBATIM COPYING}
+\addcontentsline{toc}{section}{2. VERBATIM COPYING}
+\end{center}
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+
+\begin{center}
+{\Large\bf 3. COPYING IN QUANTITY}
+\addcontentsline{toc}{section}{3. COPYING IN QUANTITY}
+\end{center}
+
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+
+\begin{center}
+{\Large\bf 4. MODIFICATIONS}
+\addcontentsline{toc}{section}{4. MODIFICATIONS}
+\end{center}
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+\begin{itemize}
+\item[A.]
+ Use in the Title Page (and on the covers, if any) a title distinct
+ from that of the Document, and from those of previous versions
+ (which should, if there were any, be listed in the History section
+ of the Document). You may use the same title as a previous version
+ if the original publisher of that version gives permission.
+
+\item[B.]
+ List on the Title Page, as authors, one or more persons or entities
+ responsible for authorship of the modifications in the Modified
+ Version, together with at least five of the principal authors of the
+ Document (all of its principal authors, if it has fewer than five),
+ unless they release you from this requirement.
+
+\item[C.]
+ State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+
+\item[D.]
+ Preserve all the copyright notices of the Document.
+
+\item[E.]
+ Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+
+\item[F.]
+ Include, immediately after the copyright notices, a license notice
+ giving the public permission to use the Modified Version under the
+ terms of this License, in the form shown in the Addendum below.
+
+\item[G.]
+ Preserve in that license notice the full lists of Invariant Sections
+ and required Cover Texts given in the Document's license notice.
+
+\item[H.]
+ Include an unaltered copy of this License.
+
+\item[I.]
+ Preserve the section Entitled "History", Preserve its Title, and add
+ to it an item stating at least the title, year, new authors, and
+ publisher of the Modified Version as given on the Title Page. If
+ there is no section Entitled "History" in the Document, create one
+ stating the title, year, authors, and publisher of the Document as
+ given on its Title Page, then add an item describing the Modified
+ Version as stated in the previous sentence.
+
+\item[J.]
+ Preserve the network location, if any, given in the Document for
+ public access to a Transparent copy of the Document, and likewise
+ the network locations given in the Document for previous versions
+ it was based on. These may be placed in the "History" section.
+ You may omit a network location for a work that was published at
+ least four years before the Document itself, or if the original
+ publisher of the version it refers to gives permission.
+
+\item[K.]
+ For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the section all
+ the substance and tone of each of the contributor acknowledgements
+ and/or dedications given therein.
+
+\item[L.]
+ Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section titles.
+
+\item[M.]
+ Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+
+\item[N.]
+ Do not retitle any existing section to be Entitled "Endorsements"
+ or to conflict in title with any Invariant Section.
+
+\item[O.]
+ Preserve any Warranty Disclaimers.
+\end{itemize}
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled "Endorsements", provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+
+\begin{center}
+{\Large\bf 5. COMBINING DOCUMENTS}
+\addcontentsline{toc}{section}{5. COMBINING DOCUMENTS}
+\end{center}
+
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled "History"
+in the various original documents, forming one section Entitled
+"History"; likewise combine any sections Entitled "Acknowledgements",
+and any sections Entitled "Dedications". You must delete all sections
+Entitled "Endorsements".
+
+\begin{center}
+{\Large\bf 6. COLLECTIONS OF DOCUMENTS}
+\addcontentsline{toc}{section}{6. COLLECTIONS OF DOCUMENTS}
+\end{center}
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+
+\begin{center}
+{\Large\bf 7. AGGREGATION WITH INDEPENDENT WORKS}
+\addcontentsline{toc}{section}{7. AGGREGATION WITH INDEPENDENT WORKS}
+\end{center}
+
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an "aggregate" if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+
+\begin{center}
+{\Large\bf 8. TRANSLATION}
+\addcontentsline{toc}{section}{8. TRANSLATION}
+\end{center}
+
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers. In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled "Acknowledgements",
+"Dedications", or "History", the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+
+\begin{center}
+{\Large\bf 9. TERMINATION}
+\addcontentsline{toc}{section}{9. TERMINATION}
+\end{center}
+
+
+You may not copy, modify, sublicense, or distribute the Document except
+as expressly provided for under this License. Any other attempt to
+copy, modify, sublicense or distribute the Document is void, and will
+automatically terminate your rights under this License. However,
+parties who have received copies, or rights, from you under this
+License will not have their licenses terminated so long as such
+parties remain in full compliance.
+

+\chapter{File Services Daemon}
+\label{_ChapterStart11}
+\index{File Services Daemon }
+\index{Daemon!File Services }
+\addcontentsline{toc}{section}{File Services Daemon}
+
+Please note, this section is somewhat out of date as the code has evolved
+significantly. The basic idea has not changed though.
+
+This chapter is intended to be a technical discussion of the File daemon
+services and as such is not targeted at end users but rather at developers and
+system administrators that want or need to know more of the working details of
+{\bf Bacula}.
+
+The {\bf Bacula File Services} consist of the programs that run on the system
+to be backed up and provide the interface between the Host File system and
+Bacula -- in particular, the Director and the Storage services.
+
+When time comes for a backup, the Director gets in touch with the File daemon
+on the client machine and hands it a set of ``marching orders'' which, if
+written in English, might be something like the following:
+
+OK, {\bf File daemon}, it's time for your daily incremental backup. I want you
+to get in touch with the Storage daemon on host archive.mysite.com and perform
+the following save operations with the designated options. You'll note that
+I've attached include and exclude lists and patterns you should apply when
+backing up the file system. As this is an incremental backup, you should save
+only files modified since the time you started your last backup which, as you
+may recall, was 2000-11-19-06:43:38. Please let me know when you're done and
+how it went. Thank you.
+
+So, having been handed everything it needs to decide what to dump and where to
+store it, the File daemon doesn't need to have any further contact with the
+Director until the backup is complete providing there are no errors. If there
+are errors, the error messages will be delivered immediately to the Director.
+While the backup is proceeding, the File daemon will send the file coordinates
+and data for each file being backed up to the Storage daemon, which will in
+turn pass the file coordinates to the Director to put in the catalog.
+
+During a {\bf Verify} of the catalog, the situation is different, since the
+File daemon will have an exchange with the Director for each file, and will
+not contact the Storage daemon.
+
+A {\bf Restore} operation will be very similar to the {\bf Backup} except that
+during the {\bf Restore} the Storage daemon will not send storage coordinates
+to the Director since the Director presumably already has them. On the other
+hand, any error messages from either the Storage daemon or File daemon will
+normally be sent directly to the Directory (this, of course, depends on how
+the Message resource is defined).

+\chapter{Bacula Developer Notes}
+\label{_ChapterStart10}

+\index{Notes!Bacula Developer}
+\addcontentsline{toc}{section}{Bacula Developer Notes}
+
+This document is intended mostly for developers and describes how you can
+contribute to the Bacula project and the the general
+framework of making Bacula source changes.
+
+\subsection{Contributions}
+\index{Contributions}
+\addcontentsline{toc}{subsubsection}{Contributions}
+
+Contributions to the Bacula project come in many forms: ideas,
+participation in helping people on the bacula-users email list,
+packaging Bacula binaries for the community, helping improve
+the documentation, and submitting code.
+
+Contributions in the form of submissions for inclusion in the project are
+broken into two groups. The first are contributions that are aids and not
+essential to Bacula. In general, these will be scripts or will go into and
+examples or contributions directory. For these kinds of non-essential
+contributions there is no obligation to do a copyright assignment as
+described below. However, a copyright assignment would still be
+appreciated.
+
+The second class of contributions are those which will be integrated with
+Bacula and become an essential part (code, scripts, documentation, ...)
+Within this class of contributions, there are two hurdles to surmount. One
+is getting your patch accepted, and two is dealing with copyright issues.
+The following text describes some of the requirements for such code.
+
+\subsection{Patches}
+\index{Patches}
+\addcontentsline{toc}{subsubsection}{Patches}
+
+Subject to the copyright assignment described below, your patches should be
+sent in {\bf diff -u} format relative to the current contents of the Source
+Forge SVN. The diff -u format is the easiest for us to understand and integrate.
+Please be sure to use the Bacula indenting standard (see below) for source code.
+If you have checked out the source with SVN, you can get a diff using:
+
+\begin{verbatim}
+svn update
+svn diff > change.patch
+\end{verbatim}
+
+If you plan on doing significant development work over a period of time,
+after having your first patch reviewed and approved, you will be eligible
+for having developer SVN write access so that you can commit your changes
+directly to the SVN repository. To do so, you will need a userid on Source
+Forge.
+
+\subsection{Copyrights}
+\index{Copyrights}
+\addcontentsline{toc}{subsubsection}{Copyrights}
+
+To avoid future problems concerning changing licensing or
+copyrights, all code contributions more than a hand full of lines
+must be in the Public Domain or have the copyright transferred to
+the Free Software Foundation Europe e.V. with a Fiduciary License
+Agreement (FLA) as in the current code. Note, prior to
+November 2004, the code was copyrighted by Kern Sibbald and John
+Walker. After November 2004, the code was copyrighted by Kern
+Sibbald, then on the 15th of November 2006, the copyright was
+transferred to the Free Software Foundation Europe e.V.
+In signing the FLA and transferring the copyright, you retain the
+right to use the code you have submitted as you want.
+
+Your name should be clearly indicated as the author of the code, and you
+must be extremely careful not to violate any copyrights or patents or use other
+people's code without acknowledging it. The purpose of this requirement is
+to avoid future copyright, patent, or intellectual property problems.
+Please read the LICENSE agreement in the main Bacula source code
+directory. When you sign the Fiduciary License Agreement (FLA)
+and send it in, you are argeeing to the terms of that LICENSE
+file.
+
+If you don't understand what we mean by future problems, please
+examine the difficulties Mozilla was having finding
+previous contributors at \elink{
+http://www.mozilla.org/MPL/missing.html}
+{http://www.mozilla.org/MPL/missing.html}. The other important issue is to
+avoid copyright, patent, or intellectual property violations as was
+(May 2003) claimed by SCO against IBM.
+
+Although the copyright will be held by the Free Software
+Foundation Europe e.V., each developer is expected to indicate
+that he wrote and/or modified a particular module (or file) and
+any other sources. The copyright assignment may seem a bit
+unusual, but in reality, it is not. Most large projects require
+this.
+
+If you have any doubts about this, please don't hesitate to ask. The
+objective is to assure the long term servival of the Bacula project.
+
+Items not needing a copyright assignment are: most small changes,
+enhancements, or bug fixes of 5-10 lines of code, which amount to
+less than 20% of any particular file.
+
+\subsection{Copyright Assignment -- Fiduciary License Agreement}
+\index{Copyright Assignment}
+\index{Assignment!Copyright}
+\addcontentsline{toc}{subsubsection}{Copyright Assignment -- Fiduciary License Agreement}
+
+Since this is not a commercial enterprise, and we prefer to believe in
+everyone's good faith, previously developers could assign the copyright by
+explicitly acknowledging that they do so in their first submission. This
+was sufficient if the developer is independent, or an employee of a
+not-for-profit organization or a university. However, in an effort to
+ensure that the Bacula code is really clean, beginning in August 2006, all
+previous and future developers with SVN write access will be asked to submit a
+copyright assignment (or Fiduciary License Agreement -- FLA),
+which means you agree to the LICENSE in the main source
+directory. It also means that you receive back the right to use
+the code that you have submitted.
+
+Any developer who wants to contribute and is employed by a company should
+either list the employer as the owner of the code, or get explicit
+permission from him to sign the copyright assignment. This is because in
+many countries, all work that an employee does whether on company time or
+in the employee's free time is considered to be Intellectual Property of
+the company. Obtaining official approval or an FLA from the company will
+avoid misunderstandings between the employee, the company, and the Bacula
+project. A good number of companies have already followed this procedure.
+
+The Fiduciary License Agreement is posted on the Bacula web site at:
+\elink{http://www.bacula.org/en/FLA-bacula.en.pdf}{http://www.bacula.org/en/FLA-bacula.en.pdf}
+
+The instructions for filling out this agreement are also at:
+\elink{http://www.bacula.org/?page=fsfe}{http://www.bacula.org/?page=fsfe}
+
+It should be filled out, then sent to:
+
+\begin{verbatim}
+ Kern Sibbald
+ Cotes-de-Montmoiret 9
+ 1012 Lausanne
+ Switzerland
+\end{verbatim}
+
+Please note that the above address is different from the officially
+registered office mentioned in the document. When you send in such a
+complete document, please notify me: kern at sibbald dot com, and
+please add your email address to the FLA so that I can contact you
+to confirm reception of the signed FLA.
+
+
+\section{The Development Cycle}
+\index{Developement Cycle}
+\index{Cycle!Developement}
+\addcontentsline{toc}{subsubsection}{Development Cycle}
+
+As I noted in the 1.38 ReleaseNotes, version 1.38 was different from prior
+versions because it had a lot more contributions. We expect that this trend
+will continue. As a consequence, we have modified how we do
+development, and instead of making a list of all the features that we will
+implement in the next version, each developer will sign up for one (maybe
+two) projects at a time, and when they are complete, we will release a new
+version.
+
+The difference is that we will have more time to review the new code that is
+being contributed, and will be able to devote more time to a smaller number
+of projects (1.38 had too many new features for us to handle correctly).
+
+Future release schedules will be much the same, and the
+number of new features will also be much the same providing that the
+contributions continue to come -- and they show no signs of let up :-)
+
+\index{Feature Requests}
+{\bf Feature Requests:} \\
+In addition, we would like to "formalize" the feature requests a bit.
+
+Instead of me maintaining an informal list of everything I run into
+(kernstodo), we would like to maintain a "formal" list of projects. This
+means that all new feature requests, including those recently discussed on
+the email lists, must be formally submitted and approved.
+
+Formal submission of feature requests will take two forms: \\
+1. non-mandatory, but highly recommended is to discuss proposed new features
+on the mailing list.\\
+2. Formal submission of an Feature Request in a special format.
+We'll give an example of this below, but you can also find it on the web
+site under "Support -\gt{} Feature Requests". Since it takes a bit of time to
+properly fill out a Feature Request form, you probably should check on the email list
+first.
+
+Once the Feature Request is received by the keeper of the projects list, it
+will be sent to the Bacula project manager (Kern), and he will either
+accept it, send it back asking for clarification, send it to the email list
+asking for opinions, or reject it.
+
+If it is accepted, it will go in the "projects" file (a simple ASCII file)
+maintained in the main Bacula source directory.
+
+{\bf Implementation of Feature Requests:}\\
+Any qualified developer can sign up for a project. The project must have
+an entry in the projects file, and the developer's name will appear in the
+Status field.
+
+{\bf How Feature Requests are accepted:}\\
+Acceptance of Feature Requests depends on several things: \\
+1. feedback from users. If it is negative, the Feature Request will probably not be
+accepted. \\
+2. the difficulty of the project. A project that is so
+difficult that we cannot imagine finding someone to implement probably won't
+be accepted. Obviously if you know how to implement it, don't hesitate
+to put it in your Feature Request \\
+ 3. whether or not the Feature Request fits within the
+current stategy of Bacula (for example an Feature Request that requests changing the
+tape to tar format probably would not be accepted, ...).
+
+{\bf How Feature Requests are prioritized:}\\
+Once an Feature Request is accepted, it needs to be implemented. If you
+can find a developer for it, or one signs up for implementing it, then the
+Feature Request becomes top priority (at least for that developer).
+
+Between releases of Bacula, we will generally solicit Feature Request input
+for the next version, and by way of this email, we suggest that you send
+discuss and send in your Feature Requests for the next release. Please
+verify that the Feature Request is not in the current list (attached to this email).
+
+Once users have had several weeks to submit Feature Requests, the keeper of
+the projects list will organize them, and request users to vote on them.
+This will allow fixing prioritizing the Feature Requests. Having a
+priority is one thing, but getting it implement is another thing -- we are
+hoping that the Bacula community will take more responsibility for assuring
+the implementation of accepted Feature Requests.
+
+Feature Request format:
+\begin{verbatim}
+============= Empty Feature Request form ===========
+Item n: One line summary ...
+ Date: Date submitted
+ Origin: Name and email of originator.
+ Status:
+
+ What: More detailed explanation ...
+
+ Why: Why it is important ...
+
+ Notes: Additional notes or features (omit if not used)
+============== End Feature Request form ==============
+\end{verbatim}
+
+\begin{verbatim}
+============= Example Completed Feature Request form ===========
+Item 1: Implement a Migration job type that will move the job
+ data from one device to another.
+ Origin: Sponsored by Riege Sofware International GmbH. Contact:
+ Daniel Holtkamp <holtkamp at riege dot com>
+ Date: 28 October 2005
+ Status: Partially coded in 1.37 -- much more to do. Assigned to
+ Kern.
+
+ What: The ability to copy, move, or archive data that is on a
+ device to another device is very important.
+
+ Why: An ISP might want to backup to disk, but after 30 days
+ migrate the data to tape backup and delete it from
+ disk. Bacula should be able to handle this
+ automatically. It needs to know what was put where,
+ and when, and what to migrate -- it is a bit like
+ retention periods. Doing so would allow space to be
+ freed up for current backups while maintaining older
+ data on tape drives.
+
+ Notes: Migration could be triggered by:
+ Number of Jobs
+ Number of Volumes
+ Age of Jobs
+ Highwater size (keep total size)
+ Lowwater mark
+=================================================

+\section{Bacula Code Submissions and Projects}
+\index{Submissions and Projects}
+\addcontentsline{toc}{subsection}{Code Submissions and Projects}
+
+Getting code implemented in Bacula works roughly as follows:
+
+\begin{itemize}
+
+\item Kern is the project manager, but prefers not to be a "gate keeper".
+ This means that the developers are expected to be self-motivated,
+ and once they have experience submit directly to the SVN. However,
+ it is a good idea to have your patches reviewed prior to submitting,
+ and it is a bad idea to submit monster patches because no one will
+ be able to properly review them. See below for more details on this.
+
+\item There are growing numbers of contributions (very good).
+
+\item Some contributions come in the form of relatively small patches,
+ which Kern reviews, integrates, documents, tests, and maintains.
+
+\item All Bacula developers take full
+ responsibility for writing the code, posting as patches so that we can
+ review it as time permits, integrating it at an appropriate time,
+ responding to our requests for tweaking it (name changes, ...),
+ document it in the code, document it in the manual (even though
+ their mother tongue is not English), test it, develop and commit
+ regression scripts, and answer in a timely fashion all bug reports --
+ even occassionally accepting additional bugs :-)
+
+ This is a sustainable way of going forward with Bacula, and the
+ direction that the project will be taking more and more. For
+ example, in the past, we have had some very dedicated programmers
+ who did major projects. However, some of these
+ programmers due to outside obligations (job responsibilities change of
+ job, school duties, ...) could not continue to maintain the code. In
+ those cases, the code suffers from lack of maintenance, sometimes we
+ patch it, sometimes not. In the end, the code gets dropped from the
+ project (there are two such contributions that are heading in that
+ direction). When ever possible, we would like to avoid this, and
+ ensure a continuation of the code and a sharing of the development,
+ debugging, documentation, and maintenance responsibilities.
+\end{itemize}
+
+\section{Patches for Released Versions}
+\index{Patches for Released Versions}
+\addcontentsline{toc}{subsection}{Patches for Released Versions}
+If you fix a bug in a released version, you should, unless it is
+an absolutely trivial bug, create and release a patch file for the
+bug. The procedure is as follows:
+
+Fix the bug in the branch and in the trunk.
+
+Make a patch file for the branch and add the branch patch to
+the patches directory in both the branch and the trunk.
+The name should be 2.2.4-xxx.patch where xxx is unique, in this case it can
+be "restore", e.g. 2.2.4-restore.patch. Add to the top of the
+file a brief description and instructions for applying it -- see for example
+2.2.4-poll-mount.patch. The best way to create the patch file is as
+follows:
+
+\begin{verbatim}
+ (edit) 2.2.4-restore.patch
+ (input description)
+ (end edit)
+
+ svn diff >>2.2.4-restore.patch
+\end{verbatim}
+
+check to make sure no extra junk got put into the patch file (i.e.
+it should have the patch for that bug only).
+
+If there is not a bug report on the problem, create one, then add the
+patch to the bug report.
+
+Uthen upload it to the 2.2.x release of bacula-patches.
+
+So, end the end, the patch file is:
+\begin{itemize}
+\item Attached to the bug report
+
+\item In Branch-2.2/bacula/patches/...
+
+\item In the trunk
+
+\item Loaded on Source Forge bacula-patches 2.2.x release. When
+ you add it, click on the check box to send an Email so that all the
+ users that are monitoring SF patches get notified.
+\end{itemize}
+
+
+
+\section{SVN Usage}
+\index{SVN Usage}
+\addcontentsline{toc}{subsection}{SVN Usage}
+
+Please note that if you are familar with CVS, SVN is very
+similar (and better), but there can be a few surprising
+differences.
+
+The *entire* Bacula SourceForge.net Subversion repository can be
+checked out through SVN with the following command:
+
+\begin{verbatim}
+svn checkout https://bacula.svn.sourceforge.net/svnroot/bacula bacula
+\end{verbatim}
+
+With the above command, you will get everything, which is a very large
+amount of data:
+
+\begin{verbatim}
+branches/
+ Branch-1.32a/
+ ...
+ Branch-2.0/
+ import/
+ vendor/
+tags/
+ Release-1.1/
+ ...
+ Release-2.0.2/
+trunk/
+ bacula/
+ docs/
+ gui/
+ regress/
+ rescue/
+\end{verbatim}
+
+Note, you should NEVER commit code to any checkout that you have
+done of a tag. All tags (e.g. Release-1.1, ... Release-2.0.2)
+should be considered read-only.
+
+You may commit code to the most recent item in
+branches (in the above the most recent one is Branch-2.0). If
+you want to commit code to an older branch, then please contact
+Kern first.
+
+You may create your own tags and/or branches, but they should
+have a name clearly distinctive from Branch-, Release-, or Beta-,
+which are official names used by the project. If you create a
+tag, then you should NEVER commit code to it, for the same
+reason noted above -- it should serve as a marker for something
+you released. If you create a branch, then you are free to
+commit to it as you wish.
+
+You may, of course, commit to the trunk.
+
+In summary:
+
+\begin{verbatim}
+branches
+ Branch-nnn
+tags
+ Release-nnn
+ Beta-nnn
+\end{verbatim}
+
+are reserved names to be created only by the project manager (or
+with his OK), where the nnn is any sequence of numbers and
+periods (e.g. 2.0, 2.0.1, ...).
+
+In addition all tags even those that you create are read-only
+forever. Typically tags represent release points either in the
+trunc or in a branch.
+
+
+Coming back to getting source code.
+If you only want the current Bacula source code, you could use:
+
+\begin{verbatim}
+svn checkout https://bacula.svn.sourceforge.net/svnroot/bacula/trunk/bacula bacula
+\end{verbatim}
+
+To view what is in the SVN, point your browser at the following URL:
+http://bacula.svn.sourceforge.net/viewvc/bacula/
+
+Many of the Subversion (svn) commands are almost identical to those that
+you have used for cvs, but some (such as a checkout) can have surprising
+results, so you should take a careful look at the documentation.
+
+The following documentation on the new
+svn repository will help you know how to use it:
+
+Here is the list of branches:
+\begin{verbatim}
+ Branch-1.32a
+ Branch-1.32e
+ Branch-1.34.2
+ Branch-1.34.5
+ Branch-1.36
+ Branch-1.36.1
+ Branch-1.36.2
+ Branch-1.38
+ Branch-2.0
+ import
+ vendor
+\end{verbatim}
+
+The list of tags is:
+\begin{verbatim}
+ Release-1.1 Release-1.19 Release-1.19a Release-1.19b

+
+
+Let's say you are working in the directory scripts. You would then do:
+
+\begin{verbatim}
+cd scripts
+(edit some files)
+\end{verbatim}
+
+when you are happy with your changes, you can do the following:
+
+\begin{verbatim}
+cd bacula (to your top level directory)
+svn diff my-changes.patch
+\end{verbatim}
+
+When the command is done, you can look in the file my-changes.patch
+and you will see all the changes you have made to your copy of the
+repository. Make sure that you understand all the changes that
+it reports before proceeding. If you modified files that you do
+do not want to commit to the main repository, you can simply delete
+them from your local directory, and they will be restored from the
+repository with the "svn update" that is shown below. Normally, you
+should not find changes to files that you do not want to commit, and
+if you find yourself in that position a lot, you are probably doing
+something wrong.
+
+Let's assume that now you want to commit your changes to the main
+SVN repository.
+
+First do:
+
+\begin{verbatim}
+cd bacula
+svn update
+\end{verbatim}
+
+When you do this, it will pull any changes made by other developers into
+your local copy of the repository, and it will check for conflicts. If there
+are any, it will tell you, and you will need to resolve them. The problems
+of resolving conflicts are a bit more than this document can cover, but
+you can examine the files it claims have conflicts and look for \lt{}\lt{}\lt{}\lt{}
+or look in the .rej files that it creates. If you have problems, just ask
+on the developer's list.
+
+Note, doing the above "svn update" is not absolutely necessary. There are
+times when you may be working on code and you want to commit it, but you
+explicitly do not want to move up to the latest version of the code in
+the SVN. If that is the case, you can simply skip the "svn update" and
+do the commit shown below. If the commit fails because of a conflict, it
+will tell you, and you must resolve the conflict before it will permit
+you to do the commit.
+
+Once your local copy of the repository has been updated, you can now
+commit your changes:
+
+\begin{verbatim}
+svn commit -m "Some comment about what you changed"
+\end{verbatim}
+
+or if you really only want to commit a single file, you can
+do:
+
+\begin{verbatim}
+svn commit -m "comment" scripts/file-I-edited
+\end{verbatim}
+
+Note, if you have done a build in your directory, or you have added
+other new files, the commit will update only the files that are
+actually in the repository. For example, none of the object files
+are stored in the repository, so when you do a commit, those object
+files will simply be ignored.
+
+If you want to add new files or remove files from the main SVN
+repository, and you are not experienced with SVN, please ask Kern
+to do it. If you follow the simple steps above, it is unlikely that
+you will do any damage to the repository, and if you do, it is always
+possible for us to recover, but it can be painful.
+
+If you are only working in one subdirectory of say the bacula project,
+for example, the scripts directory, you can do your commit from
+that subdirectory, and only the changes in that directory and all its
+subdirectories will be committed. This can be helpful for translators.
+If you are doing a French translation, you will be working in
+docs/manual-fr, and if you are always cd'ed into that directory when
+doing your commits, your commit will effect only that directory. As
+long as you are careful only to change files that you want changed,
+you have little to worry about.

+\section{Developing Bacula}
+\index{Developing Bacula}
+\index{Bacula!Developing}
+\addcontentsline{toc}{subsubsection}{Developing Bacula}
+
+Typically the simplest way to develop Bacula is to open one xterm window
+pointing to the source directory you wish to update; a second xterm window at
+the top source directory level, and a third xterm window at the bacula
+directory \lt{}top\gt{}/src/bacula. After making source changes in one of the
+directories, in the top source directory xterm, build the source, and start
+the daemons by entering:
+
+make and
+
+./startit then in the enter:
+
+./console or
+
+./gnome-console to start the Console program. Enter any commands for testing.
+For example: run kernsverify full.
+
+Note, the instructions here to use {\bf ./startit} are different from using a
+production system where the administrator starts Bacula by entering {\bf
+./bacula start}. This difference allows a development version of {\bf Bacula}
+to be run on a computer at the same time that a production system is running.
+The {\bf ./startit} strip starts {\bf Bacula} using a different set of
+configuration files, and thus permits avoiding conflicts with any production
+system.
+
+To make additional source changes, exit from the Console program, and in the
+top source directory, stop the daemons by entering:
+
+./stopit then repeat the process.
+
+\subsection{Debugging}
+\index{Debugging}
+\addcontentsline{toc}{subsubsection}{Debugging}
+
+Probably the first thing to do is to turn on debug output.
+
+A good place to start is with a debug level of 20 as in {\bf ./startit -d20}.
+The startit command starts all the daemons with the same debug level.
+Alternatively, you can start the appropriate daemon with the debug level you
+want. If you really need more info, a debug level of 60 is not bad, and for
+just about everything a level of 200.
+
+\subsection{Using a Debugger}
+\index{Using a Debugger}
+\index{Debugger!Using a}
+\addcontentsline{toc}{subsubsection}{Using a Debugger}
+
+If you have a serious problem such as a segmentation fault, it can usually be
+found quickly using a good multiple thread debugger such as {\bf gdb}. For
+example, suppose you get a segmentation violation in {\bf bacula-dir}. You
+might use the following to find the problem:
+
+\lt{}start the Storage and File daemons\gt{}
+cd dird
+gdb ./bacula-dir
+run -f -s -c ./dird.conf
+\lt{}it dies with a segmentation fault\gt{}
+where
+The {\bf -f} option is specified on the {\bf run} command to inhibit {\bf
+dird} from going into the background. You may also want to add the {\bf -s}
+option to the run command to disable signals which can potentially interfere
+with the debugging.
+
+As an alternative to using the debugger, each {\bf Bacula} daemon has a built
+in back trace feature when a serious error is encountered. It calls the
+debugger on itself, produces a back trace, and emails the report to the
+developer. For more details on this, please see the chapter in the main Bacula
+manual entitled ``What To Do When Bacula Crashes (Kaboom)''.
+
+\subsection{Memory Leaks}
+\index{Leaks!Memory}
+\index{Memory Leaks}
+\addcontentsline{toc}{subsubsection}{Memory Leaks}
+
+Because Bacula runs routinely and unattended on client and server machines, it
+may run for a long time. As a consequence, from the very beginning, Bacula
+uses SmartAlloc to ensure that there are no memory leaks. To make detection of
+memory leaks effective, all Bacula code that dynamically allocates memory MUST
+have a way to release it. In general when the memory is no longer needed, it
+should be immediately released, but in some cases, the memory will be held
+during the entire time that Bacula is executing. In that case, there MUST be a
+routine that can be called at termination time that releases the memory. In
+this way, we will be able to detect memory leaks. Be sure to immediately
+correct any and all memory leaks that are printed at the termination of the
+daemons.

+\subsection{Header Files}
+\index{Header Files}
+\index{Files!Header}
+\addcontentsline{toc}{subsubsection}{Header Files}
+
+Please carefully follow the scheme defined below as it permits in general only
+two header file includes per C file, and thus vastly simplifies programming.
+With a large complex project like Bacula, it isn't always easy to ensure that
+the right headers are invoked in the right order (there are a few kludges to
+make this happen -- i.e. in a few include files because of the chicken and egg
+problem, certain references to typedefs had to be replaced with {\bf void} ).
+
+Every file should include {\bf bacula.h}. It pulls in just about everything,
+with very few exceptions. If you have system dependent ifdefing, please do it
+in {\bf baconfig.h}. The version number and date are kept in {\bf version.h}.
+
+Each of the subdirectories (console, cats, dird, filed, findlib, lib, stored,
+...) contains a single directory dependent include file generally the name of
+the directory, which should be included just after the include of {\bf
+bacula.h}. This file (for example, for the dird directory, it is {\bf dird.h})
+contains either definitions of things generally needed in this directory, or
+it includes the appropriate header files. It always includes {\bf protos.h}.
+See below.
+
+Each subdirectory contains a header file named {\bf protos.h}, which contains
+the prototypes for subroutines exported by files in that directory. {\bf
+protos.h} is always included by the main directory dependent include file.
+
+\subsection{Programming Standards}
+\index{Standards!Programming}
+\index{Programming Standards}
+\addcontentsline{toc}{subsubsection}{Programming Standards}
+
+For the most part, all code should be written in C unless there is a burning
+reason to use C++, and then only the simplest C++ constructs will be used.
+Note, Bacula is slowly evolving to use more and more C++.
+
+Code should have some documentation -- not a lot, but enough so that I can
+understand it. Look at the current code, and you will see that I document more
+than most, but am definitely not a fanatic.
+
+We prefer simple linear code where possible. Gotos are strongly discouraged
+except for handling an error to either bail out or to retry some code, and
+such use of gotos can vastly simplify the program.
+
+Remember this is a C program that is migrating to a {\bf tiny} subset of C++,
+so be conservative in your use of C++ features.

+\addcontentsline{toc}{subsubsection}{Do Not Use}

+\begin{itemize}
+ \item STL -- it is totally incomprehensible.
+\end{itemize}
+
+\subsection{Avoid if Possible}
+\index{Possible!Avoid if}
+\index{Avoid if Possible}
+\addcontentsline{toc}{subsubsection}{Avoid if Possible}
+
+\begin{itemize}
+\item Using {\bf void *} because this generally means that one must
+ using casting, and in C++ casting is rather ugly. It is OK to use
+ void * to pass structure address where the structure is not known
+ to the routines accepting the packet (typically callback routines).
+ However, declaring "void *buf" is a bad idea. Please use the
+ correct types whenever possible.
+
+\item Using undefined storage specifications such as (short, int, long,
+ long long, size\_t ...). The problem with all these is that the number of bytes
+ they allocate depends on the compiler and the system. Instead use
+ Bacula's types (int8\_t, uint8\_t, int32\_t, uint32\_t, int64\_t, and
+ uint64\_t). This guarantees that the variables are given exactly the
+ size you want. Please try at all possible to avoid using size\_t ssize\_t
+ and the such. They are very system dependent. However, some system
+ routines may need them, so their use is often unavoidable.
+
+\item Returning a malloc'ed buffer from a subroutine -- someone will forget
+ to release it.
+
+\item Heap allocation (malloc) unless needed -- it is expensive. Use
+ POOL\_MEM instead.
+
+\item Templates -- they can create portability problems.
+
+\item Fancy or tricky C or C++ code, unless you give a good explanation of
+ why you used it.
+
+\item Too much inheritance -- it can complicate the code, and make reading it
+ difficult (unless you are in love with colons)
+
+\end{itemize}
+
+\subsection{Do Use Whenever Possible}

+\index{Do Use Whenever Possible}
+\addcontentsline{toc}{subsubsection}{Do Use Whenever Possible}

+\begin{itemize}
+\item Locking and unlocking within a single subroutine.
+
+\item A single point of exit from all subroutines. A goto is
+ perfectly OK to use to get out early, but only to a label
+ named bail\_out, and possibly an ok\_out. See current code
+ examples.
+
+\item Malloc and free within a single subroutine.
+
+\item Comments and global explanations on what your code or algorithm does.

+\end{itemize}
+
+\subsection{Indenting Standards}
+\index{Standards!Indenting}
+\index{Indenting Standards}
+\addcontentsline{toc}{subsubsection}{Indenting Standards}
+
+We find it very hard to read code indented 8 columns at a time.
+Even 4 at a time uses a lot of space, so we have adopted indenting
+3 spaces at every level. Note, indention is the visual appearance of the
+source on the page, while tabbing is replacing a series of up to 8 spaces from
+a tab character.
+
+The closest set of parameters for the Linux {\bf indent} program that will
+produce reasonably indented code are:
+
+\footnotesize
+\begin{verbatim}
+-nbad -bap -bbo -nbc -br -brs -c36 -cd36 -ncdb -ce -ci3 -cli0
+-cp36 -d0 -di1 -ndj -nfc1 -nfca -hnl -i3 -ip0 -l85 -lp -npcs
+-nprs -npsl -saf -sai -saw -nsob -nss -nbc -ncs -nbfda
+\end{verbatim}
+\normalsize
+
+You can put the above in your .indent.pro file, and then just invoke indent on
+your file. However, be warned. This does not produce perfect indenting, and it
+will mess up C++ class statements pretty badly.
+
+Braces are required in all if statements (missing in some very old code). To
+avoid generating too many lines, the first brace appears on the first line
+(e.g. of an if), and the closing brace is on a line by itself. E.g.
+
+\footnotesize
+\begin{verbatim}
+ if (abc) {
+ some_code;
+ }
+\end{verbatim}
+\normalsize
+
+Just follow the convention in the code. For example we I prefer non-indented cases.
+
+\footnotesize
+\begin{verbatim}
+ switch (code) {
+ case 'A':
+ do something
+ break;
+ case 'B':
+ again();
+ break;
+ default:
+ break;
+ }
+\end{verbatim}
+\normalsize
+
+Avoid using // style comments except for temporary code or turning off debug
+code. Standard C comments are preferred (this also keeps the code closer to
+C).
+
+Attempt to keep all lines less than 85 characters long so that the whole line
+of code is readable at one time. This is not a rigid requirement.
+
+Always put a brief description at the top of any new file created describing
+what it does and including your name and the date it was first written. Please
+don't forget any Copyrights and acknowledgments if it isn't 100\% your code.
+Also, include the Bacula copyright notice that is in {\bf src/c}.
+
+In general you should have two includes at the top of the an include for the
+particular directory the code is in, for includes are needed, but this should
+be rare.
+
+In general (except for self-contained packages), prototypes should all be put
+in {\bf protos.h} in each directory.
+
+Always put space around assignment and comparison operators.
+
+\footnotesize
+\begin{verbatim}
+ a = 1;
+ if (b >= 2) {
+ cleanup();
+ }
+\end{verbatim}
+\normalsize
+
+but your can compress things in a {\bf for} statement:
+
+\footnotesize
+\begin{verbatim}
+ for (i=0; i < del.num_ids; i++) {
+ ...
+\end{verbatim}
+\normalsize
+
+Don't overuse the inline if (?:). A full {\bf if} is preferred, except in a
+print statement, e.g.:
+
+\footnotesize
+\begin{verbatim}
+ if (ua->verbose \&& del.num_del != 0) {
+ bsendmsg(ua, _("Pruned %d %s on Volume %s from catalog.\n"), del.num_del,
+ del.num_del == 1 ? "Job" : "Jobs", mr->VolumeName);
+ }
+\end{verbatim}
+\normalsize
+
+Leave a certain amount of debug code (Dmsg) in code you submit, so that future
+problems can be identified. This is particularly true for complicated code
+likely to break. However, try to keep the debug code to a minimum to avoid
+bloating the program and above all to keep the code readable.
+
+Please keep the same style in all new code you develop. If you include code
+previously written, you have the option of leaving it with the old indenting
+or re-indenting it. If the old code is indented with 8 spaces, then please
+re-indent it to Bacula standards.
+
+If you are using {\bf vim}, simply set your tabstop to 8 and your shiftwidth
+to 3.
+
+\subsection{Tabbing}
+\index{Tabbing}
+\addcontentsline{toc}{subsubsection}{Tabbing}
+
+Tabbing (inserting the tab character in place of spaces) is as normal on all
+Unix systems -- a tab is converted space up to the next column multiple of 8.
+My editor converts strings of spaces to tabs automatically -- this results in
+significant compression of the files. Thus, you can remove tabs by replacing
+them with spaces if you wish. Please don't confuse tabbing (use of tab
+characters) with indenting (visual alignment of the code).
+
+\subsection{Don'ts}
+\index{Don'ts}
+\addcontentsline{toc}{subsubsection}{Don'ts}
+
+Please don't use:
+
+\footnotesize
+\begin{verbatim}
+strcpy()
+strcat()
+strncpy()
+strncat();
+sprintf()
+snprintf()
+\end{verbatim}
+\normalsize
+
+They are system dependent and un-safe. These should be replaced by the Bacula
+safe equivalents:
+
+\footnotesize
+\begin{verbatim}
+char *bstrncpy(char *dest, char *source, int dest_size);
+char *bstrncat(char *dest, char *source, int dest_size);
+int bsnprintf(char *buf, int32_t buf_len, const char *fmt, ...);
+int bvsnprintf(char *str, int32_t size, const char *format, va_list ap);
+\end{verbatim}
+\normalsize
+
+See src/lib/bsys.c for more details on these routines.
+
+Don't use the {\bf \%lld} or the {\bf \%q} printf format editing types to edit
+64 bit integers -- they are not portable. Instead, use {\bf \%s} with {\bf
+edit\_uint64()}. For example:
+
+\footnotesize
+\begin{verbatim}
+ char buf[100];
+ uint64_t num = something;
+ char ed1[50];
+ bsnprintf(buf, sizeof(buf), "Num=%s\n", edit_uint64(num, ed1));
+\end{verbatim}
+\normalsize
+
+Note: {\bf \%lld} is now permitted in Bacula code -- we have our
+own printf routines which handle it correctly. The edit\_uint64() subroutine
+can still be used if you wish, but over time, most of that old style will
+be removed.
+
+The edit buffer {\bf ed1} must be at least 27 bytes long to avoid overflow.
+See src/lib/edit.c for more details. If you look at the code, don't start
+screaming that I use {\bf lld}. I actually use subtle trick taught to me by
+John Walker. The {\bf lld} that appears in the editing routine is actually
+{\bf \#define} to a what is needed on your OS (usually ``lld'' or ``q'') and
+is defined in autoconf/configure.in for each OS. C string concatenation causes
+the appropriate string to be concatenated to the ``\%''.
+
+Also please don't use the STL or Templates or any complicated C++ code.

+\index{Debug Messages}
+\addcontentsline{toc}{subsubsection}{Debug Messages}
+
+Debug messages are designed to be turned on at a specified debug level and are
+always sent to STDOUT. There are designed to only be used in the development
+debug process. They are coded as:
+
+DmsgN(level, message, arg1, ...) where the N is a number indicating how many
+arguments are to be substituted into the message (i.e. it is a count of the
+number arguments you have in your message -- generally the number of percent
+signs (\%)). {\bf level} is the debug level at which you wish the message to
+be printed. message is the debug message to be printed, and arg1, ... are the
+arguments to be substituted. Since not all compilers support \#defines with
+varargs, you must explicitly specify how many arguments you have.
+
+When the debug message is printed, it will automatically be prefixed by the
+name of the daemon which is running, the filename where the Dmsg is, and the
+line number within the file.
+
+Some actual examples are:
+
+Dmsg2(20, ``MD5len=\%d MD5=\%s\textbackslash{}n'', strlen(buf), buf);
+
+Dmsg1(9, ``Created client \%s record\textbackslash{}n'', client->hdr.name);

+\addcontentsline{toc}{subsubsection}{Error Messages}
+
+Error messages are messages that are related to the daemon as a whole rather
+than a particular job. For example, an out of memory condition my generate an
+error message. They should be very rarely needed. In general, you should be
+using Job and Job Queued messages (Jmsg and Qmsg). They are coded as:
+
+EmsgN(error-code, level, message, arg1, ...) As with debug messages, you must
+explicitly code the of arguments to be substituted in the message. error-code
+indicates the severity or class of error, and it may be one of the following:
+
+\addcontentsline{lot}{table}{Message Error Code Classes}
+\begin{longtable}{lp{3in}}
+{{\bf M\_ABORT} } & {Causes the daemon to immediately abort. This should be
+used only in extreme cases. It attempts to produce a traceback. } \\
+{{\bf M\_ERROR\_TERM} } & {Causes the daemon to immediately terminate. This
+should be used only in extreme cases. It does not produce a traceback. } \\
+{{\bf M\_FATAL} } & {Causes the daemon to terminate the current job, but the
+daemon keeps running } \\
+{{\bf M\_ERROR} } & {Reports the error. The daemon and the job continue
+running } \\
+{{\bf M\_WARNING} } & {Reports an warning message. The daemon and the job
+continue running } \\
+{{\bf M\_INFO} } & {Reports an informational message.}
+
+\end{longtable}
+
+There are other error message classes, but they are in a state of being
+redesigned or deprecated, so please do not use them. Some actual examples are:
+
+
+Emsg1(M\_ABORT, 0, ``Cannot create message thread: \%s\textbackslash{}n'',
+strerror(status));
+
+Emsg3(M\_WARNING, 0, ``Connect to File daemon \%s at \%s:\%d failed. Retrying
+...\textbackslash{}n'', client-\gt{}hdr.name, client-\gt{}address,
+client-\gt{}port);
+
+Emsg3(M\_FATAL, 0, ``bdird\lt{}filed: bad response from Filed to \%s command:
+\%d \%s\textbackslash{}n'', cmd, n, strerror(errno));
+
+\subsection{Job Messages}
+\index{Job Messages}
+\index{Messages!Job}
+\addcontentsline{toc}{subsubsection}{Job Messages}
+
+Job messages are messages that pertain to a particular job such as a file that
+could not be saved, or the number of files and bytes that were saved. They
+Are coded as:
+\begin{verbatim}
+Jmsg(jcr, M\_FATAL, 0, "Text of message");
+\end{verbatim}
+A Jmsg with M\_FATAL will fail the job. The Jmsg() takes varargs so can
+have any number of arguments for substituted in a printf like format.
+Output from the Jmsg() will go to the Job report.
+<br>
+If the Jmsg is followed with a number such as Jmsg1(...), the number
+indicates the number of arguments to be substituted (varargs is not
+standard for \#defines), and what is more important is that the file and
+line number will be prefixed to the message. This permits a sort of debug
+from user's output.
+
+\subsection{Queued Job Messages}
+\index{Queued Job Messages}
+\index{Messages!Job}
+\addcontentsline{toc}{subsubsection}{Queued Job Messages}
+Queued Job messages are similar to Jmsg()s except that the message is
+Queued rather than immediately dispatched. This is necessary within the
+network subroutines and in the message editing routines. This is to prevent
+recursive loops, and to ensure that messages can be delivered even in the
+event of a network error.
+
+
+\subsection{Memory Messages}
+\index{Messages!Memory}
+\index{Memory Messages}
+\addcontentsline{toc}{subsubsection}{Memory Messages}
+
+Memory messages are messages that are edited into a memory buffer. Generally
+they are used in low level routines such as the low level device file dev.c in
+the Storage daemon or in the low level Catalog routines. These routines do not
+generally have access to the Job Control Record and so they return error
+essages reformatted in a memory buffer. Mmsg() is the way to do this.
+
+\subsection{Bugs Database}
+\index{Database!Bugs}
+\index{Bugs Database}
+\addcontentsline{toc}{subsubsection}{Bugs Database}
+We have a bugs database which is at:
+\elink{http://bugs.bacula.org}{http://bugs.bacula.org}, and as
+a developer you will need to respond to bugs, perhaps bugs in general
+if you have time, otherwise just bugs that correspond to code that
+you wrote.
+
+If you need to answer bugs, please be sure to ask the Project Manager
+(currently Kern) to give you Developer access to the bugs database. This
+allows you to modify statuses and close bugs.
+
+The first thing is if you want to take over a bug, rather than just make a
+note, you should assign the bug to yourself. This helps other developers
+know that you are the principal person to deal with the bug. You can do so
+by going into the bug and clicking on the {\bf Update Issue} button. Then
+you simply go to the {\bf Assigned To} box and select your name from the
+drop down box. To actually update it you must click on the {\bf Update
+Information} button a bit further down on the screen, but if you have other
+things to do such as add a Note, you might wait before clicking on the {\bf
+Update Information} button.
+
+Generally, we set the {\bf Status} field to either acknowledged, confirmed,
+or feedback when we first start working on the bug. Feedback is set when
+we expect that the user should give us more information.
+
+Normally, once you are reasonably sure that the bug is fixed, and a patch
+is made and attached to the bug report, and/or in the SVN, you can close
+the bug. If you want the user to test the patch, then leave the bug open,
+otherwise close it and set {\bf Resolution} to {\bf Fixed}. We generally
+close bug reports rather quickly, even without confirmation, especially if
+we have run tests and can see that for us the problem is fixed. However,
+in doing so, it avoids misunderstandings if you leave a note while you are
+closing the bug that says something to the following effect:
+We are closing this bug because ... If for some reason, it does not fix
+your problem, please feel free to reopen it, or to open a new bug report
+describing the problem".
+
+We do not recommend that you attempt to edit any of the bug notes that have
+been submitted, nor to delete them or make them private. In fact, if
+someone accidentally makes a bug note private, you should ask the reason
+and if at all possible (with his agreement) make the bug note public.
+
+If the user has not properly filled in most of the important fields
+(platorm, OS, Product Version, ...) please do not hesitate to politely ask
+him. Also, if the bug report is a request for a new feature, please
+politely send the user to the Feature Request menu item on www.bacula.org.
+The same applies to a support request (we answer only bugs), you might give
+the user a tip, but please politely refer him to the manual and the
+Getting Support page of www.bacula.org.

+# ___________________
+#
+# For the multiple-index style, each index is identified by the ref argument to \newindex, \index,
+# and \printindex. A default index is allowed, which is indicated by omitting the optional
+# argument. The default index does not require a \newindex command. As \index commands
+# are encountered, their entries are stored according
+# to the ref argument. When the \printindex command is encountered, the stored index
+# entries for that argument are retrieved and printed. The title for each index is taken
+# from the last argument in the \newindex command.
+# While processing \index and \printindex commands, if no argument is given the index entries
+# are built into a default index. The title of the default index is simply "Index".
+# This makes the difference between single- and multiple-index processing trivial.
+#
+# Another method can be used by omitting the \printindex command and just using \include to
+# pull in index files created by the makeindex program. These files will start with
+# \begin{theindex}. This command is used to determine where to print the index. Using this
+# approach, the indices will be output in the same order as the newindex commands were
+# originally found (see below). Using a combination of \printindex and \include{indexfile} has not
+# been tested and may produce undesireable results.
+#
+# The index data are stored in a hash for later sorting and output. As \printindex
+# commands are handled, the order in which they were found in the tex filea is saved,
+# associated with the ref argument to \printindex.
+#
+# We use the original %index hash to store the index data into. We append a \002 followed by the
+# name of the index to isolate the entries in different indices from each other. This is necessary
+# so that different indices can have entries with the same name. For the default index, the \002 is
+# appended without the name.
+#
+# Since the index order in the output cannot be determined if the \include{indexfile}
+# command is used, the order will be assumed from the order in which the \newindex
+# commands were originally seen in the TeX files. This order is saved as well as the
+# order determined from any printindex{ref} commands. If \printindex commnads are used
+# to specify the index output, that order will be used. If the \include{idxfile} command
+# is used, the order of the original newindex commands will be used. In this case the
+# default index will be printed last since it doesn't have a corresponding \newindex
+# command and its order cannot be determined. Mixing \printindex and \include{idxfile}
+# commands in the same file is likely to produce less than satisfactory results.
+#
+#
+# The hash containing index data is named %indices. It contains the following data:
+#{
+# 'title' => {
+# $ref1 => $indextitle ,
+# $ref2 => $indextitle ,
+# ...
+# },
+# 'newcmdorder' => [ ref1, ref2, ..., * ], # asterisk indicates the position of the default index.
+# 'printindorder' => [ ref1, ref2, ..., * ], # asterisk indicates the position of the default index.

+\addcontentsline{toc}{subsubsection}{Description}
+
+A {\it message digest} is a compact digital signature for an arbitrarily long
+stream of binary data. An ideal message digest algorithm would never generate
+the same signature for two different sets of input, but achieving such
+theoretical perfection would require a message digest as long as the input
+file. Practical message digest algorithms compromise in favour of a digital
+signature of modest size created with an algorithm designed to make
+preparation of input text with a given signature computationally infeasible.
+Message digest algorithms have much in common with techniques used in
+encryption, but to a different end; verification that data have not been
+altered since the signature was published.
+
+Many older programs requiring digital signatures employed 16 or 32 bit {\it
+cyclical redundancy codes} (CRC) originally developed to verify correct
+transmission in data communication protocols, but these short codes, while
+adequate to detect the kind of transmission errors for which they were
+intended, are insufficiently secure for applications such as electronic
+commerce and verification of security related software distributions.
+
+The most commonly used present-day message digest algorithm is the 128 bit MD5
+algorithm, developed by Ron Rivest of the
+\elink{MIT}{http://web.mit.edu/}
+\elink{Laboratory for Computer Science}{http://www.lcs.mit.edu/} and
+\elink{RSA Data Security, Inc.}{http://www.rsa.com/} The algorithm, with a
+reference implementation, was published as Internet
+\elink{RFC 1321}{http://www.fourmilab.ch/md5/rfc1321.html} in April 1992, and
+was placed into the public domain at that time. Message digest algorithms such
+as MD5 are not deemed ``encryption technology'' and are not subject to the
+export controls some governments impose on other data security products.
+(Obviously, the responsibility for obeying the laws in the jurisdiction in
+which you reside is entirely your own, but many common Web and Mail utilities
+use MD5, and I am unaware of any restrictions on their distribution and use.)
+
+The MD5 algorithm has been implemented in numerous computer languages
+including C,
+\elink{Perl}{http://www.perl.org/}, and
+\elink{Java}{http://www.javasoft.com/}; if you're writing a program in such a
+language, track down a suitable subroutine and incorporate it into your
+program. The program described on this page is a {\it command line}
+implementation of MD5, intended for use in shell scripts and Perl programs (it
+is much faster than computing an MD5 signature directly in Perl). This {\bf
+md5} program was originally developed as part of a suite of tools intended to
+monitor large collections of files (for example, the contents of a Web site)
+to detect corruption of files and inadvertent (or perhaps malicious) changes.
+That task is now best accomplished with more comprehensive packages such as
+\elink{Tripwire}{ftp://coast.cs.purdue.edu/pub/COAST/Tripwire/}, but the
+command line {\bf md5} component continues to prove useful for verifying
+correct delivery and installation of software packages, comparing the contents
+of two different systems, and checking for changes in specific files.

+\addcontentsline{toc}{section}{Storage Media Output Format}
+
+\section{General}
+\index{General}
+\addcontentsline{toc}{subsection}{General}
+
+This document describes the media format written by the Storage daemon. The
+Storage daemon reads and writes in units of blocks. Blocks contain records.
+Each block has a block header followed by records, and each record has a
+record header followed by record data.
+
+This chapter is intended to be a technical discussion of the Media Format and
+as such is not targeted at end users but rather at developers and system
+administrators that want or need to know more of the working details of {\bf
+Bacula}.
+
+\section{Definitions}
+\index{Definitions}
+\addcontentsline{toc}{subsection}{Definitions}
+
+\begin{description}
+
+\item [Block]
+ \index{Block}
+ A block represents the primitive unit of information that the Storage daemon
+reads and writes to a physical device. Normally, for a tape device, it will
+be the same as a tape block. The Storage daemon always reads and writes
+blocks. A block consists of block header information followed by records.
+Clients of the Storage daemon (the File daemon) normally never see blocks.
+However, some of the Storage tools (bls, bscan, bextract, ...) may be use
+block header information. In older Bacula tape versions, a block could
+contain records (see record definition below) from multiple jobs. However,
+all blocks currently written by Bacula are block level BB02, and a given
+block contains records for only a single job. Different jobs simply have
+their own private blocks that are intermingled with the other blocks from
+other jobs on the Volume (previously the records were intermingled within
+the blocks). Having only records from a single job in any give block
+permitted moving the VolumeSessionId and VolumeSessionTime (see below) from
+each record heading to the Block header. This has two advantages: 1. a block
+can be quickly rejected based on the contents of the header without reading
+all the records. 2. because there is on the average more than one record per
+block, less data is written to the Volume for each job.
+
+\item [Record]
+ \index{Record}
+ A record consists of a Record Header, which is managed by the Storage daemon
+and Record Data, which is the data received from the Client. A record is the
+primitive unit of information sent to and from the Storage daemon by the
+Client (File daemon) programs. The details are described below.
+
+\item [JobId]
+ \index{JobId}
+ A number assigned by the Director daemon for a particular job. This number
+will be unique for that particular Director (Catalog). The daemons use this
+number to keep track of individual jobs. Within the Storage daemon, the JobId
+may not be unique if several Directors are accessing the Storage daemon
+simultaneously.
+
+\item [Session]
+ \index{Session}
+ A Session is a concept used in the Storage daemon corresponds one to one to a
+Job with the exception that each session is uniquely identified within the
+Storage daemon by a unique SessionId/SessionTime pair (see below).
+
+\item [VolSessionId]
+ \index{VolSessionId}
+ A unique number assigned by the Storage daemon to a particular session (Job)
+it is having with a File daemon. This number by itself is not unique to the
+given Volume, but with the VolSessionTime, it is unique.
+
+\item [VolSessionTime]
+ \index{VolSessionTime}
+ A unique number assigned by the Storage daemon to a particular Storage daemon
+execution. It is actually the Unix time\_t value of when the Storage daemon
+began execution cast to a 32 bit unsigned integer. The combination of the
+{\bf VolSessionId} and the {\bf VolSessionTime} for a given Storage daemon is
+guaranteed to be unique for each Job (or session).
+
+\item [FileIndex]
+ \index{FileIndex}
+ A sequential number beginning at one assigned by the File daemon to the files
+within a job that are sent to the Storage daemon for backup. The Storage
+daemon ensures that this number is greater than zero and sequential. Note,
+the Storage daemon uses negative FileIndexes to flag Session Start and End
+Labels as well as End of Volume Labels. Thus, the combination of
+VolSessionId, VolSessionTime, and FileIndex uniquely identifies the records
+for a single file written to a Volume.
+
+\item [Stream]
+ \index{Stream}
+ While writing the information for any particular file to the Volume, there
+can be any number of distinct pieces of information about that file, e.g. the
+attributes, the file data, ... The Stream indicates what piece of data it
+is, and it is an arbitrary number assigned by the File daemon to the parts
+(Unix attributes, Win32 attributes, data, compressed data,\ ...) of a file
+that are sent to the Storage daemon. The Storage daemon has no knowledge of
+the details of a Stream; it simply represents a numbered stream of bytes. The
+data for a given stream may be passed to the Storage daemon in single record,
+or in multiple records.
+
+\item [Block Header]
+ \index{Block Header}
+ A block header consists of a block identification (``BB02''), a block length
+in bytes (typically 64,512) a checksum, and sequential block number. Each
+block starts with a Block Header and is followed by Records. Current block
+headers also contain the VolSessionId and VolSessionTime for the records
+written to that block.
+
+\item [Record Header]
+ \index{Record Header}
+ A record header contains the Volume Session Id, the Volume Session Time, the
+FileIndex, the Stream, and the size of the data record which follows. The
+Record Header is always immediately followed by a Data Record if the size
+given in the Header is greater than zero. Note, for Block headers of level
+BB02 (version 1.27 and later), the Record header as written to tape does not
+contain the Volume Session Id and the Volume Session Time as these two
+fields are stored in the BB02 Block header. The in-memory record header does
+have those fields for convenience.
+
+\item [Data Record]
+ \index{Data Record}
+ A data record consists of a binary stream of bytes and is always preceded by
+a Record Header. The details of the meaning of the binary stream of bytes are
+unknown to the Storage daemon, but the Client programs (File daemon) defines
+and thus knows the details of each record type.
+
+\item [Volume Label]
+ \index{Volume Label}
+ A label placed by the Storage daemon at the beginning of each storage volume.
+It contains general information about the volume. It is written in Record
+format. The Storage daemon manages Volume Labels, and if the client wants, he
+may also read them.
+
+\item [Begin Session Label]
+ \index{Begin Session Label}
+ The Begin Session Label is a special record placed by the Storage daemon on
+the storage medium as the first record of an append session job with a File
+daemon. This record is useful for finding the beginning of a particular
+session (Job), since no records with the same VolSessionId and VolSessionTime
+will precede this record. This record is not normally visible outside of the
+Storage daemon. The Begin Session Label is similar to the Volume Label except
+that it contains additional information pertaining to the Session.
+
+\item [End Session Label]
+ \index{End Session Label}
+ The End Session Label is a special record placed by the Storage daemon on the
+storage medium as the last record of an append session job with a File
+daemon. The End Session Record is distinguished by a FileIndex with a value
+of minus two (-2). This record is useful for detecting the end of a
+particular session since no records with the same VolSessionId and
+VolSessionTime will follow this record. This record is not normally visible
+outside of the Storage daemon. The End Session Label is similar to the Volume
+Label except that it contains additional information pertaining to the
+Session.
+\end{description}
+
+\section{Storage Daemon File Output Format}
+\index{Format!Storage Daemon File Output}
+\index{Storage Daemon File Output Format}
+\addcontentsline{toc}{subsection}{Storage Daemon File Output Format}
+
+The file storage and tape storage formats are identical except that tape
+records are by default blocked into blocks of 64,512 bytes, except for the
+last block, which is the actual number of bytes written rounded up to a
+multiple of 1024 whereas the last record of file storage is not rounded up.
+The default block size of 64,512 bytes may be overridden by the user (some
+older tape drives only support block sizes of 32K). Each Session written to
+tape is terminated with an End of File mark (this will be removed later).
+Sessions written to file are simply appended to the end of the file.
+
+\section{Overall Format}
+\index{Format!Overall}
+\index{Overall Format}
+\addcontentsline{toc}{subsection}{Overall Format}
+
+A Bacula output file consists of Blocks of data. Each block contains a block
+header followed by records. Each record consists of a record header followed
+by the record data. The first record on a tape will always be the Volume Label
+Record.
+
+No Record Header will be split across Bacula blocks. However, Record Data may
+be split across any number of Bacula blocks. Obviously this will not be the
+case for the Volume Label which will always be smaller than the Bacula Block
+size.
+
+To simplify reading tapes, the Start of Session (SOS) and End of Session (EOS)
+records are never split across blocks. If this is about to happen, Bacula will
+write a short block before writing the session record (actually, the SOS
+record should always be the first record in a block, excepting perhaps the
+Volume label).
+
+Due to hardware limitations, the last block written to the tape may not be
+fully written. If your drive permits backspace record, Bacula will backup over
+the last record written on the tape, re-read it and verify that it was
+correctly written.
+
+When a new tape is mounted Bacula will write the full contents of the
+partially written block to the new tape ensuring that there is no loss of
+data. When reading a tape, Bacula will discard any block that is not totally
+written, thus ensuring that there is no duplication of data. In addition,
+since Bacula blocks are sequentially numbered within a Job, it is easy to
+ensure that no block is missing or duplicated.
+
+\section{Serialization}
+\index{Serialization}
+\addcontentsline{toc}{subsection}{Serialization}
+
+All Block Headers, Record Headers, and Label Records are written using
+Bacula's serialization routines. These routines guarantee that the data is
+written to the output volume in a machine independent format.
+
+\section{Block Header}
+\index{Header!Block}
+\index{Block Header}
+\addcontentsline{toc}{subsection}{Block Header}
+
+The format of the Block Header (version 1.27 and later) is:
+
+\footnotesize
+\begin{verbatim}
+ uint32_t CheckSum; /* Block check sum */
+ uint32_t BlockSize; /* Block byte size including the header */
+ uint32_t BlockNumber; /* Block number */
+ char ID[4] = "BB02"; /* Identification and block level */
+ uint32_t VolSessionId; /* Session Id for Job */
+ uint32_t VolSessionTime; /* Session Time for Job */
+\end{verbatim}
+\normalsize
+
+The Block header is a fixed length and fixed format and is followed by Record
+Headers and Record Data. The CheckSum field is a 32 bit checksum of the block
+data and the block header but not including the CheckSum field. The Block
+Header is always immediately followed by a Record Header. If the tape is
+damaged, a Bacula utility will be able to recover as much information as
+possible from the tape by recovering blocks which are valid. The Block header
+is written using the Bacula serialization routines and thus is guaranteed to
+be in machine independent format. See below for version 2 of the block header.
+
+
+\section{Record Header}
+\index{Header!Record}
+\index{Record Header}
+\addcontentsline{toc}{subsection}{Record Header}
+
+Each binary data record is preceded by a Record Header. The Record Header is
+fixed length and fixed format, whereas the binary data record is of variable
+length. The Record Header is written using the Bacula serialization routines
+and thus is guaranteed to be in machine independent format.
+
+The format of the Record Header (version 1.27 or later) is:
+
+\footnotesize
+\begin{verbatim}
+ int32_t FileIndex; /* File index supplied by File daemon */
+ int32_t Stream; /* Stream number supplied by File daemon */
+ uint32_t DataSize; /* size of following data record in bytes */
+\end{verbatim}
+\normalsize
+
+This record is followed by the binary Stream data of DataSize bytes, followed
+by another Record Header record and the binary stream data. For the definitive
+definition of this record, see record.h in the src/stored directory.
+

+assures that the combination of VolSessionId and VolSessionTime is unique for
+every jobs written to the tape, even if there was a machine crash between two
+writes.
+
+\item [The {\bf FileIndex} ]
+ \index{FileIndex}
+ is a sequential file number within a job. The Storage daemon requires this
+index to be greater than zero and sequential. Note, however, that the File
+daemon may send multiple Streams for the same FileIndex. In addition, the
+Storage daemon uses negative FileIndices to hold the Begin Session Label, the
+End Session Label, and the End of Volume Label.
+
+\item [The {\bf Stream} ]
+ \index{Stream}
+ is defined by the File daemon and is used to identify separate parts of the
+data saved for each file (Unix attributes, Win32 attributes, file data,
+compressed file data, sparse file data, ...). The Storage Daemon has no idea
+of what a Stream is or what it contains except that the Stream is required to
+be a positive integer. Negative Stream numbers are used internally by the
+Storage daemon to indicate that the record is a continuation of the previous
+record (the previous record would not entirely fit in the block).
+
+For Start Session and End Session Labels (where the FileIndex is negative),
+the Storage daemon uses the Stream field to contain the JobId. The current
+stream definitions are:
+
+\footnotesize
+\begin{verbatim}
+#define STREAM_UNIX_ATTRIBUTES 1 /* Generic Unix attributes */
+#define STREAM_FILE_DATA 2 /* Standard uncompressed data */
+#define STREAM_MD5_SIGNATURE 3 /* MD5 signature for the file */
+#define STREAM_GZIP_DATA 4 /* GZip compressed file data */
+/* Extended Unix attributes with Win32 Extended data. Deprecated. */
+#define STREAM_UNIX_ATTRIBUTES_EX 5 /* Extended Unix attr for Win32 EX */
+#define STREAM_SPARSE_DATA 6 /* Sparse data stream */
+#define STREAM_SPARSE_GZIP_DATA 7
+#define STREAM_PROGRAM_NAMES 8 /* program names for program data */
+#define STREAM_PROGRAM_DATA 9 /* Data needing program */
+#define STREAM_SHA1_SIGNATURE 10 /* SHA1 signature for the file */
+#define STREAM_WIN32_DATA 11 /* Win32 BackupRead data */
+#define STREAM_WIN32_GZIP_DATA 12 /* Gzipped Win32 BackupRead data */
+#define STREAM_MACOS_FORK_DATA 13 /* Mac resource fork */
+#define STREAM_HFSPLUS_ATTRIBUTES 14 /* Mac OS extra attributes */
+#define STREAM_UNIX_ATTRIBUTES_ACCESS_ACL 15 /* Standard ACL attributes on UNIX */
+#define STREAM_UNIX_ATTRIBUTES_DEFAULT_ACL 16 /* Default ACL attributes on UNIX */
+\end{verbatim}
+\normalsize
+
+\item [The {\bf DataSize} ]
+ \index{DataSize}
+ is the size in bytes of the binary data record that follows the Session
+Record header. The Storage Daemon has no idea of the actual contents of the
+binary data record. For standard Unix files, the data record typically
+contains the file attributes or the file data. For a sparse file the first
+64 bits of the file data contains the storage address for the data block.
+\end{description}
+
+The Record Header is never split across two blocks. If there is not enough
+room in a block for the full Record Header, the block is padded to the end
+with zeros and the Record Header begins in the next block. The data record, on
+the other hand, may be split across multiple blocks and even multiple physical
+volumes. When a data record is split, the second (and possibly subsequent)
+piece of the data is preceded by a new Record Header. Thus each piece of data
+is always immediately preceded by a Record Header. When reading a record, if
+Bacula finds only part of the data in the first record, it will automatically
+read the next record and concatenate the data record to form a full data
+record.

+\section{Version BB02 Block Header}
+\index{Version BB02 Block Header}
+\index{Header!Version BB02 Block}
+\addcontentsline{toc}{subsection}{Version BB02 Block Header}
+
+Each session or Job has its own private block. As a consequence, the SessionId
+and SessionTime are written once in each Block Header and not in the Record
+Header. So, the second and current version of the Block Header BB02 is:
+
+\footnotesize
+\begin{verbatim}
+ uint32_t CheckSum; /* Block check sum */
+ uint32_t BlockSize; /* Block byte size including the header */
+ uint32_t BlockNumber; /* Block number */
+ char ID[4] = "BB02"; /* Identification and block level */
+ uint32_t VolSessionId; /* Applies to all records */
+ uint32_t VolSessionTime; /* contained in this block */
+\end{verbatim}
+\normalsize
+
+As with the previous version, the BB02 Block header is a fixed length and
+fixed format and is followed by Record Headers and Record Data. The CheckSum
+field is a 32 bit CRC checksum of the block data and the block header but not
+including the CheckSum field. The Block Header is always immediately followed
+by a Record Header. If the tape is damaged, a Bacula utility will be able to
+recover as much information as possible from the tape by recovering blocks
+which are valid. The Block header is written using the Bacula serialization
+routines and thus is guaranteed to be in machine independent format.
+
+\section{Version 2 Record Header}
+\index{Version 2 Record Header}
+\index{Header!Version 2 Record}
+\addcontentsline{toc}{subsection}{Version 2 Record Header}
+
+Version 2 Record Header is written to the medium when using Version BB02 Block
+Headers. The memory representation of the record is identical to the old BB01
+Record Header, but on the storage medium, the first two fields, namely
+VolSessionId and VolSessionTime are not written. The Block Header is filled
+with these values when the First user record is written (i.e. non label
+record) so that when the block is written, it will have the current and unique
+VolSessionId and VolSessionTime. On reading each record from the Block, the
+VolSessionId and VolSessionTime is filled in the Record Header from the Block
+Header.
+
+\section{Volume Label Format}
+\index{Volume Label Format}
+\index{Format!Volume Label}
+\addcontentsline{toc}{subsection}{Volume Label Format}
+
+Tape volume labels are created by the Storage daemon in response to a {\bf
+label} command given to the Console program, or alternatively by the {\bf
+btape} program. created. Each volume is labeled with the following information
+using the Bacula serialization routines, which guarantee machine byte order
+independence.
+
+For Bacula versions 1.27 and later, the Volume Label Format is:
+
+\footnotesize
+\begin{verbatim}
+ char Id[32]; /* Bacula 1.0 Immortal\n */
+ uint32_t VerNum; /* Label version number */
+ /* VerNum 11 and greater Bacula 1.27 and later */
+ btime_t label_btime; /* Time/date tape labeled */
+ btime_t write_btime; /* Time/date tape first written */
+ /* The following are 0 in VerNum 11 and greater */
+ float64_t write_date; /* Date this label written */
+ float64_t write_time; /* Time this label written */
+ char VolName[128]; /* Volume name */
+ char PrevVolName[128]; /* Previous Volume Name */
+ char PoolName[128]; /* Pool name */
+ char PoolType[128]; /* Pool type */
+ char MediaType[128]; /* Type of this media */
+ char HostName[128]; /* Host name of writing computer */
+ char LabelProg[32]; /* Label program name */
+ char ProgVersion[32]; /* Program version */
+ char ProgDate[32]; /* Program build date/time */
+\end{verbatim}
+\normalsize
+
+Note, the LabelType (Volume Label, Volume PreLabel, Session Start Label, ...)
+is stored in the record FileIndex field of the Record Header and does not
+appear in the data part of the record.
+
+\section{Session Label}
+\index{Label!Session}
+\index{Session Label}
+\addcontentsline{toc}{subsection}{Session Label}
+
+The Session Label is written at the beginning and end of each session as well
+as the last record on the physical medium. It has the following binary format:
+
+
+\footnotesize
+\begin{verbatim}
+ char Id[32]; /* Bacula Immortal ... */
+ uint32_t VerNum; /* Label version number */
+ uint32_t JobId; /* Job id */
+ uint32_t VolumeIndex; /* sequence no of vol */
+ /* Prior to VerNum 11 */
+ float64_t write_date; /* Date this label written */
+ /* VerNum 11 and greater */
+ btime_t write_btime; /* time/date record written */
+ /* The following is zero VerNum 11 and greater */
+ float64_t write_time; /* Time this label written */
+ char PoolName[128]; /* Pool name */
+ char PoolType[128]; /* Pool type */
+ char JobName[128]; /* base Job name */
+ char ClientName[128];
+ /* Added in VerNum 10 */
+ char Job[128]; /* Unique Job name */
+ char FileSetName[128]; /* FileSet name */
+ uint32_t JobType;
+ uint32_t JobLevel;
+\end{verbatim}
+\normalsize
+
+In addition, the EOS label contains:
+
+\footnotesize
+\begin{verbatim}
+ /* The remainder are part of EOS label only */
+ uint32_t JobFiles;
+ uint64_t JobBytes;
+ uint32_t start_block;
+ uint32_t end_block;
+ uint32_t start_file;
+ uint32_t end_file;
+ uint32_t JobErrors;
+\end{verbatim}
+\normalsize
+
+In addition, for VerNum greater than 10, the EOS label contains (in addition
+to the above):
+
+\footnotesize
+\begin{verbatim}
+ uint32_t JobStatus /* Job termination code */
+\end{verbatim}
+\normalsize
+
+: Note, the LabelType (Volume Label, Volume PreLabel, Session Start Label,
+...) is stored in the record FileIndex field and does not appear in the data
+part of the record. Also, the Stream field of the Record Header contains the
+JobId. This permits quick filtering without actually reading all the session

+ Current Bacula Tape Format
+ 6 June 2001
+ Version BB02 added 28 September 2002
+ Version BB01 is the old deprecated format.
+ A Bacula tape is composed of tape Blocks. Each block
+ has a Block header followed by the block data. Block
+ Data consists of Records. Records consist of Record
+ Headers followed by Record Data.
+ :=======================================================:
+ | |
+ | Block Header (24 bytes) |
+ | |
+ |-------------------------------------------------------|
+ | |
+ | Record Header (12 bytes) |
+ | |
+ |-------------------------------------------------------|
+ | |
+ | Record Data |
+ | |
+ |-------------------------------------------------------|
+ | |
+ | Record Header (12 bytes) |
+ | |
+ |-------------------------------------------------------|
+ | |
+ | ... |
+ Block Header: the first item in each block. The format is
+ shown below.
+ Partial Data block: occurs if the data from a previous
+ block spills over to this block (the normal case except
+ for the first block on a tape). However, this partial
+ data block is always preceded by a record header.
+ Record Header: identifies the Volume Session, the Stream
+ and the following Record Data size. See below for format.
+ Record data: arbitrary binary data.
+ Block Header Format BB02
+ :=======================================================:
+ | CheckSum (uint32_t) |
+ |-------------------------------------------------------|
+ | BlockSize (uint32_t) |
+ |-------------------------------------------------------|
+ | BlockNumber (uint32_t) |
+ |-------------------------------------------------------|
+ | "BB02" (char [4]) |
+ |-------------------------------------------------------|
+ | VolSessionId (uint32_t) |
+ |-------------------------------------------------------|
+ | VolSessionTime (uint32_t) |
+ :=======================================================:
+ BBO2: Serves to identify the block as a
+ Bacula block and also servers as a block format identifier
+ should we ever need to change the format.
+ BlockSize: is the size in bytes of the block. When reading
+ back a block, if the BlockSize does not agree with the
+ actual size read, Bacula discards the block.
+ CheckSum: a checksum for the Block.
+ BlockNumber: is the sequential block number on the tape.
+ VolSessionId: a unique sequential number that is assigned
+ by the Storage Daemon to a particular Job.
+ This number is sequential since the start
+ of execution of the daemon.
+ VolSessionTime: the time/date that the current execution
+ of the Storage Daemon started. It assures
+ that the combination of VolSessionId and
+ VolSessionTime is unique for all jobs
+ written to the tape, even if there was a
+ machine crash between two writes.
+ Record Header Format BB02
+ :=======================================================:
+ | FileIndex (int32_t) |
+ |-------------------------------------------------------|
+ | Stream (int32_t) |
+ |-------------------------------------------------------|
+ | DataSize (uint32_t) |
+ :=======================================================:
+ FileIndex: a sequential file number within a job. The
+ Storage daemon enforces this index to be
+ greater than zero and sequential. Note,
+ however, that the File daemon may send
+ multiple Streams for the same FileIndex.
+ The Storage Daemon uses negative FileIndices
+ to identify Session Start and End labels
+ as well as the End of Volume labels.
+ Stream: defined by the File daemon and is intended to be
+ used to identify separate parts of the data
+ saved for each file (attributes, file data,
+ ...). The Storage Daemon has no idea of
+ what a Stream is or what it contains.
+ DataSize: the size in bytes of the binary data record
+ that follows the Session Record header.
+ The Storage Daemon has no idea of the
+ actual contents of the binary data record.
+ For standard Unix files, the data record
+ typically contains the file attributes or
+ the file data. For a sparse file
+ the first 64 bits of the data contains
+ the storage address for the data block.

+\index{Bacula Memory Management}
+\addcontentsline{toc}{section}{Bacula Memory Management}
+
+\section{General}
+\index{General}
+\addcontentsline{toc}{subsection}{General}
+
+This document describes the memory management routines that are used in Bacula
+and is meant to be a technical discussion for developers rather than part of
+the user manual.
+
+Since Bacula may be called upon to handle filenames of varying and more or
+less arbitrary length, special attention needs to be used in the code to
+ensure that memory buffers are sufficiently large. There are four
+possibilities for memory usage within {\bf Bacula}. Each will be described in
+turn. They are:
+
+\begin{itemize}
+\item Statically allocated memory.
+\item Dynamically allocated memory using malloc() and free().
+\item Non-pooled memory.
+\item Pooled memory.
+ \end{itemize}
+
+\subsection{Statically Allocated Memory}
+\index{Statically Allocated Memory}
+\index{Memory!Statically Allocated}
+\addcontentsline{toc}{subsubsection}{Statically Allocated Memory}
+
+Statically allocated memory is of the form:
+
+\footnotesize
+\begin{verbatim}
+char buffer[MAXSTRING];
+\end{verbatim}
+\normalsize
+
+The use of this kind of memory is discouraged except when you are 100\% sure
+that the strings to be used will be of a fixed length. One example of where
+this is appropriate is for {\bf Bacula} resource names, which are currently
+limited to 127 characters (MAX\_NAME\_LENGTH). Although this maximum size may
+change, particularly to accommodate Unicode, it will remain a relatively small
+value.
+
+\subsection{Dynamically Allocated Memory}
+\index{Dynamically Allocated Memory}
+\index{Memory!Dynamically Allocated}
+\addcontentsline{toc}{subsubsection}{Dynamically Allocated Memory}
+
+Dynamically allocated memory is obtained using the standard malloc() routines.
+As in:
+
+\footnotesize
+\begin{verbatim}
+char *buf;
+buf = malloc(256);
+\end{verbatim}
+\normalsize
+
+This kind of memory can be released with:
+
+\footnotesize
+\begin{verbatim}
+free(buf);
+\end{verbatim}
+\normalsize
+
+It is recommended to use this kind of memory only when you are sure that you
+know the memory size needed and the memory will be used for short periods of
+time -- that is it would not be appropriate to use statically allocated
+memory. An example might be to obtain a large memory buffer for reading and
+writing files. When {\bf SmartAlloc} is enabled, the memory obtained by
+malloc() will automatically be checked for buffer overwrite (overflow) during
+the free() call, and all malloc'ed memory that is not released prior to
+termination of the program will be reported as Orphaned memory.
+
+\subsection{Pooled and Non-pooled Memory}
+\index{Memory!Pooled and Non-pooled}
+\index{Pooled and Non-pooled Memory}
+\addcontentsline{toc}{subsubsection}{Pooled and Non-pooled Memory}
+
+In order to facility the handling of arbitrary length filenames and to
+efficiently handle a high volume of dynamic memory usage, we have implemented
+routines between the C code and the malloc routines. The first is called
+``Pooled'' memory, and is memory, which once allocated and then released, is
+not returned to the system memory pool, but rather retained in a Bacula memory
+pool. The next request to acquire pooled memory will return any free memory
+block. In addition, each memory block has its current size associated with the
+block allowing for easy checking if the buffer is of sufficient size. This
+kind of memory would normally be used in high volume situations (lots of
+malloc()s and free()s) where the buffer length may have to frequently change
+to adapt to varying filename lengths.
+
+The non-pooled memory is handled by routines similar to those used for pooled
+memory, allowing for easy size checking. However, non-pooled memory is
+returned to the system rather than being saved in the Bacula pool. This kind
+of memory would normally be used in low volume situations (few malloc()s and
+free()s), but where the size of the buffer might have to be adjusted
+frequently.
+
+\paragraph*{Types of Memory Pool:}
+
+Currently there are three memory pool types:
+
+\begin{itemize}
+\item PM\_NOPOOL -- non-pooled memory.
+\item PM\_FNAME -- a filename pool.
+\item PM\_MESSAGE -- a message buffer pool.
+\item PM\_EMSG -- error message buffer pool.
+ \end{itemize}
+
+\paragraph*{Getting Memory:}
+
+To get memory, one uses:
+
+\footnotesize
+\begin{verbatim}
+void *get_pool_memory(pool);
+\end{verbatim}
+\normalsize
+
+where {\bf pool} is one of the above mentioned pool names. The size of the
+memory returned will be determined by the system to be most appropriate for
+the application.
+
+If you wish non-pooled memory, you may alternatively call:
+
+\footnotesize
+\begin{verbatim}
+void *get_memory(size_t size);
+\end{verbatim}
+\normalsize
+
+The buffer length will be set to the size specified, and it will be assigned
+to the PM\_NOPOOL pool (no pooling).
+
+\paragraph*{Releasing Memory:}
+
+To free memory acquired by either of the above two calls, use:
+
+\footnotesize
+\begin{verbatim}
+void free_pool_memory(void *buffer);
+\end{verbatim}
+\normalsize
+
+where buffer is the memory buffer returned when the memory was acquired. If
+the memory was originally allocated as type PM\_NOPOOL, it will be released to
+the system, otherwise, it will be placed on the appropriate Bacula memory pool
+free chain to be used in a subsequent call for memory from that pool.
+
+\paragraph*{Determining the Memory Size:}
+
+To determine the memory buffer size, use:
+
+\footnotesize
+\begin{verbatim}
+size_t sizeof_pool_memory(void *buffer);
+\end{verbatim}
+\normalsize
+
+\paragraph*{Resizing Pool Memory:}
+
+To resize pool memory, use:
+
+\footnotesize
+\begin{verbatim}
+void *realloc_pool_memory(void *buffer);
+\end{verbatim}
+\normalsize
+
+The buffer will be reallocated, and the contents of the original buffer will
+be preserved, but the address of the buffer may change.
+
+\paragraph*{Automatic Size Adjustment:}
+
+To have the system check and if necessary adjust the size of your pooled
+memory buffer, use:
+
+\footnotesize
+\begin{verbatim}
+void *check_pool_memory_size(void *buffer, size_t new-size);
+\end{verbatim}
+\normalsize
+
+where {\bf new-size} is the buffer length needed. Note, if the buffer is
+already equal to or larger than {\bf new-size} no buffer size change will
+occur. However, if a buffer size change is needed, the original contents of
+the buffer will be preserved, but the buffer address may change. Many of the
+low level Bacula subroutines expect to be passed a pool memory buffer and use
+this call to ensure the buffer they use is sufficiently large.
+
+\paragraph*{Releasing All Pooled Memory:}
+
+In order to avoid orphaned buffer error messages when terminating the program,
+use:
+
+\footnotesize
+\begin{verbatim}
+void close_memory_pool();
+\end{verbatim}
+\normalsize
+
+to free all unused memory retained in the Bacula memory pool. Note, any memory
+not returned to the pool via free\_pool\_memory() will not be released by this
+call.
+
+\paragraph*{Pooled Memory Statistics:}
+
+For debugging purposes and performance tuning, the following call will print
+the current memory pool statistics:
+
+\footnotesize
+\begin{verbatim}
+void print_memory_pool_stats();
+\end{verbatim}
+\normalsize
+
+an example output is:
+
+\footnotesize
+\begin{verbatim}
+Pool Maxsize Maxused Inuse
+ 0 256 0 0
+ 1 256 1 0
+ 2 256 1 0
+\end{verbatim}
+\normalsize

+\chapter{TCP/IP Network Protocol}

+\index{TCP/IP Network Protocol}
+\index{Protocol!TCP/IP Network}
+\addcontentsline{toc}{section}{TCP/IP Network Protocol}
+
+\section{General}
+\index{General}
+\addcontentsline{toc}{subsection}{General}
+
+This document describes the TCP/IP protocol used by Bacula to communicate
+between the various daemons and services. The definitive definition of the
+protocol can be found in src/lib/bsock.h, src/lib/bnet.c and
+src/lib/bnet\_server.c.
+
+Bacula's network protocol is basically a ``packet oriented'' protocol built on
+a standard TCP/IP streams. At the lowest level all packet transfers are done
+with read() and write() requests on system sockets. Pipes are not used as they
+are considered unreliable for large serial data transfers between various
+hosts.
+
+Using the routines described below (bnet\_open, bnet\_write, bnet\_recv, and
+bnet\_close) guarantees that the number of bytes you write into the socket
+will be received as a single record on the other end regardless of how many
+low level write() and read() calls are needed. All data transferred are
+considered to be binary data.
+
+\section{bnet and Threads}
+\index{Threads!bnet and}
+\index{Bnet and Threads}
+\addcontentsline{toc}{subsection}{bnet and Threads}
+
+These bnet routines work fine in a threaded environment. However, they assume
+that there is only one reader or writer on the socket at any time. It is
+highly recommended that only a single thread access any BSOCK packet. The
+exception to this rule is when the socket is first opened and it is waiting
+for a job to start. The wait in the Storage daemon is done in one thread and
+then passed to another thread for subsequent handling.
+
+If you envision having two threads using the same BSOCK, think twice, then you
+must implement some locking mechanism. However, it probably would not be
+appropriate to put locks inside the bnet subroutines for efficiency reasons.
+
+\section{bnet\_open}
+\index{Bnet\_open}
+\addcontentsline{toc}{subsection}{bnet\_open}
+
+To establish a connection to a server, use the subroutine:
+
+BSOCK *bnet\_open(void *jcr, char *host, char *service, int port, int *fatal)
+bnet\_open(), if successful, returns the Bacula sock descriptor pointer to be
+used in subsequent bnet\_send() and bnet\_read() requests. If not successful,
+bnet\_open() returns a NULL. If fatal is set on return, it means that a fatal
+error occurred and that you should not repeatedly call bnet\_open(). Any error
+message will generally be sent to the JCR.
+
+\section{bnet\_send}
+\index{Bnet\_send}
+\addcontentsline{toc}{subsection}{bnet\_send}
+
+To send a packet, one uses the subroutine:
+
+int bnet\_send(BSOCK *sock) This routine is equivalent to a write() except
+that it handles the low level details. The data to be sent is expected to be
+in sock-\gt{}msg and be sock-\gt{}msglen bytes. To send a packet, bnet\_send()
+first writes four bytes in network byte order than indicate the size of the
+following data packet. It returns:
+
+\footnotesize
+\begin{verbatim}
+ Returns 0 on failure
+ Returns 1 on success
+\end{verbatim}
+\normalsize
+
+In the case of a failure, an error message will be sent to the JCR contained
+within the bsock packet.
+
+\section{bnet\_fsend}
+\index{Bnet\_fsend}
+\addcontentsline{toc}{subsection}{bnet\_fsend}
+
+This form uses:
+
+int bnet\_fsend(BSOCK *sock, char *format, ...) and it allows you to send a
+formatted messages somewhat like fprintf(). The return status is the same as
+bnet\_send.
+
+\section{Additional Error information}
+\index{Information!Additional Error}
+\index{Additional Error information}
+\addcontentsline{toc}{subsection}{Additional Error information}
+
+Fro additional error information, you can call {\bf is\_bnet\_error(BSOCK
+*bsock)} which will return 0 if there is no error or non-zero if there is an
+error on the last transmission. The {\bf is\_bnet\_stop(BSOCK *bsock)}
+function will return 0 if there no errors and you can continue sending. It
+will return non-zero if there are errors or the line is closed (no more
+transmissions should be sent).
+
+\section{bnet\_recv}
+\index{Bnet\_recv}
+\addcontentsline{toc}{subsection}{bnet\_recv}
+
+To read a packet, one uses the subroutine:
+
+int bnet\_recv(BSOCK *sock) This routine is similar to a read() except that it
+handles the low level details. bnet\_read() first reads packet length that
+follows as four bytes in network byte order. The data is read into
+sock-\gt{}msg and is sock-\gt{}msglen bytes. If the sock-\gt{}msg is not large
+enough, bnet\_recv() realloc() the buffer. It will return an error (-2) if
+maxbytes is less than the record size sent. It returns:
+
+\footnotesize
+\begin{verbatim}
+ * Returns number of bytes read
+ * Returns 0 on end of file
+ * Returns -1 on hard end of file (i.e. network connection close)
+ * Returns -2 on error
+\end{verbatim}
+\normalsize
+
+It should be noted that bnet\_recv() is a blocking read.
+
+\section{bnet\_sig}
+\index{Bnet\_sig}
+\addcontentsline{toc}{subsection}{bnet\_sig}
+
+To send a ``signal'' from one daemon to another, one uses the subroutine:
+
+int bnet\_sig(BSOCK *sock, SIGNAL) where SIGNAL is one of the following:
+
+\begin{enumerate}
+\item BNET\_EOF - deprecated use BNET\_EOD
+\item BNET\_EOD - End of data stream, new data may follow
+\item BNET\_EOD\_POLL - End of data and poll all in one
+\item BNET\_STATUS - Request full status
+\item BNET\_TERMINATE - Conversation terminated, doing close()
+\item BNET\_POLL - Poll request, I'm hanging on a read
+\item BNET\_HEARTBEAT - Heartbeat Response requested
+\item BNET\_HB\_RESPONSE - Only response permitted to HB
+\item BNET\_PROMPT - Prompt for UA
+ \end{enumerate}
+
+\section{bnet\_strerror}
+\index{Bnet\_strerror}
+\addcontentsline{toc}{subsection}{bnet\_strerror}
+
+Returns a formated string corresponding to the last error that occurred.
+
+\section{bnet\_close}
+\index{Bnet\_close}
+\addcontentsline{toc}{subsection}{bnet\_close}
+
+The connection with the server remains open until closed by the subroutine:
+
+void bnet\_close(BSOCK *sock)
+
+\section{Becoming a Server}
+\index{Server!Becoming a}
+\index{Becoming a Server}
+\addcontentsline{toc}{subsection}{Becoming a Server}
+
+The bnet\_open() and bnet\_close() routines described above are used on the
+client side to establish a connection and terminate a connection with the
+server. To become a server (i.e. wait for a connection from a client), use the
+routine {\bf bnet\_thread\_server}. The calling sequence is a bit complicated,
+please refer to the code in bnet\_server.c and the code at the beginning of
+each daemon as examples of how to call it.
+
+\section{Higher Level Conventions}
+\index{Conventions!Higher Level}
+\index{Higher Level Conventions}
+\addcontentsline{toc}{subsection}{Higher Level Conventions}
+
+Within Bacula, we have established the convention that any time a single
+record is passed, it is sent with bnet\_send() and read with bnet\_recv().
+Thus the normal exchange between the server (S) and the client (C) are:
+
+\footnotesize
+\begin{verbatim}
+S: wait for connection C: attempt connection
+S: accept connection C: bnet_send() send request
+S: bnet_recv() wait for request
+S: act on request
+S: bnet_send() send ack C: bnet_recv() wait for ack
+\end{verbatim}
+\normalsize
+
+Thus a single command is sent, acted upon by the server, and then
+acknowledged.
+
+In certain cases, such as the transfer of the data for a file, all the
+information or data cannot be sent in a single packet. In this case, the
+convention is that the client will send a command to the server, who knows
+that more than one packet will be returned. In this case, the server will
+enter a loop:
+
+\footnotesize
+\begin{verbatim}
+while ((n=bnet_recv(bsock)) > 0) {
+ act on request
+}
+if (n < 0)
+ error
+\end{verbatim}
+\normalsize
+
+The client will perform the following:
+
+\footnotesize
+\begin{verbatim}
+bnet_send(bsock);
+bnet_send(bsock);
+...
+bnet_sig(bsock, BNET_EOD);
+\end{verbatim}
+\normalsize
+
+Thus the client will send multiple packets and signal to the server when all
+the packets have been sent by sending a zero length record.

+\section{General}
+\index{General }
+\addcontentsline{toc}{subsection}{General}
+
+This chapter describes the requirements for having a
+supported platform (Operating System). In general, Bacula is
+quite portable. It supports 32 and 64 bit architectures as well
+as bigendian and littleendian machines. For full
+support, the platform (Operating System) must implement POSIX Unix
+system calls. However, for File daemon support only, a small
+compatibility library can be written to support almost any
+architecture.
+
+Currently Linux, FreeBSD, and Solaris are fully supported
+platforms, which means that the code has been tested on those
+machines and passes a full set of regression tests.
+
+In addition, the Windows File daemon is supported on most versions
+of Windows, and finally, there are a number of other platforms
+where the File daemon (client) is known to run: NetBSD, OpenBSD,
+Mac OSX, SGI, ...
+
+\section{Requirements to become a Supported Platform}
+\index{Requirements!Platform}
+\index{Platform Requirements}
+\addcontentsline{toc}{subsection}{Platform Requirements}
+
+As mentioned above, in order to become a fully supported platform, it
+must support POSIX Unix system calls. In addition, the following
+requirements must be met:
+
+\begin{itemize}
+\item The principal developer (currently Kern) must have
+ non-root ssh access to a test machine running the platform.
+\item The ideal requirements and minimum requirements
+ for this machine are given below.
+\item There must be a defined platform champion who is normally
+ a system administrator for the machine that is available. This
+ person need not be a developer/programmer but must be familiar
+ with system administration of the platform.
+\item There must be at least one person designated who will
+ run regression tests prior to each release. Releases occur
+ approximately once every 6 months, but can be more frequent.
+ It takes at most a day's effort to setup the regression scripts
+ in the beginning, and after that, they can either be run daily
+ or on demand before a release. Running the regression scripts
+ involves only one or two command line commands and is fully
+ automated.
+\item Ideally there are one or more persons who will package
+ each Bacula release.
+\item Ideally there are one or more developers who can respond to
+ and fix platform specific bugs.
+\end{itemize}
+
+Ideal requirements for a test machine:
+\begin{itemize}
+\item The principal developer will have non-root ssh access to
+ the test machine at all times.
+\item The pricipal developer will have a root password.
+\item The test machine will provide approximately 200 MB of
+ disk space for continual use.
+\item The test machine will have approximately 500 MB of free
+ disk space for temporary use.
+\item The test machine will run the most common version of the OS.
+\item The test machine will have an autochanger of DDS-4 technology
+ or later having two or more tapes.
+\item The test machine will have MySQL and/or PostgreSQL database
+ access for account "bacula" available.
+\item The test machine will have sftp access.
+\item The test machine will provide an smtp server.
+\end{itemize}
+
+Minimum requirements for a test machine:
+\begin{itemize}
+\item The principal developer will have non-root ssh access to
+ the test machine when requested approximately once a month.
+\item The pricipal developer not have root access.
+\item The test machine will provide approximately 80 MB of
+ disk space for continual use.
+\item The test machine will have approximately 300 MB of free
+ disk space for temporary use.
+\item The test machine will run the the OS.
+\item The test machine will have a tape drive of DDS-4 technology
+ or later that can be scheduled for access.
+\item The test machine will not have MySQL and/or PostgreSQL database
+ access.
+\item The test machine will have no sftp access.
+\item The test machine will provide no email access.
+\end{itemize}
+
+Bare bones test machine requirements:
+\begin{itemize}
+\item The test machine is available only to a designated
+ test person (your own machine).
+\item The designated test person runs the regession
+ tests on demand.
+\item The test machine has a tape drive available.

+\index{Porting Requirements}
+\addcontentsline{toc}{section}{Porting Requirements}
+
+In General, the following holds true:
+
+\begin{itemize}
+\item {\bf Bacula} has been compiled and run on Linux RedHat, FreeBSD, and
+ Solaris systems.
+\item In addition, clients exist on Win32, and Irix
+\item It requires GNU C++ to compile. You can try with other compilers, but
+ you are on your own. The Irix client is built with the Irix complier, but, in
+ general, you will need GNU.
+\item Your compiler must provide support for 64 bit signed and unsigned
+ integers.
+\item You will need a recent copy of the {\bf autoconf} tools loaded on your
+ system (version 2.13 or later). The {\bf autoconf} tools are used to build
+ the configuration program, but are not part of the Bacula source
+distribution.
+\item There are certain third party packages that Bacula needs. Except for
+ MySQL, they can all be found in the {\bf depkgs} and {\bf depkgs1} releases.
+\item To build the Win32 binaries, we use Microsoft VC++ standard
+ 2003. Please see the instructions in
+ bacula-source/src/win32/README.win32 for more details. If you
+ want to use VC++ Express, please see README.vc8. Our build is
+ done under the most recent version of Cygwin, but Cygwin is
+ not used in the Bacula binaries that are produced.
+ Unfortunately, we do not have the resources to help you build
+ your own version of the Win32 FD, so you are pretty much on
+ your own. You can ask the bacula-devel list for help, but
+ please don't expect much.
+\item {\bf Bacula} requires a good implementation of pthreads to work.
+\item The source code has been written with portability in mind and is mostly
+ POSIX compatible. Thus porting to any POSIX compatible operating system
+ should be relatively easy.
+\end{itemize}

+
+\begin{itemize}
+\item The first step is to ensure that you have version 2.13 or later of the
+ {\bf autoconf} tools loaded. You can skip this step, but making changes to
+ the configuration program will be difficult or impossible.
+\item The run a {\bf ./configure} command in the main source directory and
+ examine the output. It should look something like the following:
+
+\footnotesize
+\begin{verbatim}
+Configuration on Mon Oct 28 11:42:27 CET 2002:

+\normalsize
+
+The details depend on your system. The first thing to check is that it
+properly identified your host on the {\bf Host:} line. The first part (added
+in version 1.27) is the GNU four part identification of your system. The part
+after the -- is your system and the system version. Generally, if your system
+is not yet supported, you must correct these.
+\item If the {\bf ./configure} does not function properly, you must determine
+ the cause and fix it. Generally, it will be because some required system
+ routine is not available on your machine.
+\item To correct problems with detection of your system type or with routines
+ and libraries, you must edit the file {\bf
+ \lt{}bacula-src\gt{}/autoconf/configure.in}. This is the ``source'' from
+which {\bf configure} is built. In general, most of the changes for your
+system will be made in {\bf autoconf/aclocal.m4} in the routine {\bf
+BA\_CHECK\_OPSYS} or in the routine {\bf BA\_CHECK\_OPSYS\_DISTNAME}. I have
+already added the necessary code for most systems, but if yours shows up as
+{\bf unknown} you will need to make changes. Then as mentioned above, you
+will need to set a number of system dependent items in {\bf configure.in} in
+the {\bf case} statement at approximately line 1050 (depending on the Bacula
+release).
+\item The items to in the case statement that corresponds to your system are
+ the following:
+
+\begin{itemize}
+\item DISTVER -- set to the version of your operating system. Typically some
+ form of {\bf uname} obtains it.
+\item TAPEDRIVE -- the default tape drive. Not too important as the user can
+ set it as an option.
+\item PSCMD -- set to the {\bf ps} command that will provide the PID in the
+ first field and the program name in the second field. If this is not set
+ properly, the {\bf bacula stop} script will most likely not be able to stop
+Bacula in all cases.
+\item hostname -- command to return the base host name (non-qualified) of
+ your system. This is generally the machine name. Not too important as the
+ user can correct this in his configuration file.
+\item CFLAGS -- set any special compiler flags needed. Many systems need a
+ special flag to make pthreads work. See cygwin for an example.
+\item LDFLAGS -- set any special loader flags. See cygwin for an example.
+\item PTHREAD\_LIB -- set for any special pthreads flags needed during
+ linking. See freebsd as an example.
+\item lld -- set so that a ``long long int'' will be properly edited in a
+ printf() call.
+\item llu -- set so that a ``long long unsigned'' will be properly edited in
+ a printf() call.
+\item PFILES -- set to add any files that you may define is your platform
+ subdirectory. These files are used for installation of automatic system
+ startup of Bacula daemons.
+\end{itemize}
+
+\item To rebuild a new version of {\bf configure} from a changed {\bf
+ autoconf/configure.in} you enter {\bf make configure} in the top level Bacula
+ source directory. You must have done a ./configure prior to trying to rebuild
+ the configure script or it will get into an infinite loop.
+\item If the {\bf make configure} gets into an infinite loop, ctl-c it, then
+ do {\bf ./configure} (no options are necessary) and retry the {\bf make
+ configure}, which should now work.
+\item To rebuild {\bf configure} you will need to have {\bf autoconf} version
+ 2.57-3 or higher loaded. Older versions of autoconf will complain about
+ unknown or bad options, and won't work.
+\item After you have a working {\bf configure} script, you may need to make a
+ few system dependent changes to the way Bacula works. Generally, these are
+ done in {\bf src/baconfig.h}. You can find a few examples of system dependent
+changes toward the end of this file. For example, on Irix systems, there is
+no definition for {\bf socklen\_t}, so it is made in this file. If your
+system has structure alignment requirements, check the definition of BALIGN
+in this file. Currently, all Bacula allocated memory is aligned on a {\bf
+double} boundary.
+\item If you are having problems with Bacula's type definitions, you might
+ look at {\bf src/bc\_types.h} where all the types such as {\bf uint32\_t},
+ {\bf uint64\_t}, etc. that Bacula uses are defined.

+\addcontentsline{toc}{section}{Smart Memory Allocation With Orphaned Buffer
+Detection}
+
+Few things are as embarrassing as a program that leaks, yet few errors are so
+easy to commit or as difficult to track down in a large, complicated program
+as failure to release allocated memory. SMARTALLOC replaces the standard C
+library memory allocation functions with versions which keep track of buffer
+allocations and releases and report all orphaned buffers at the end of program
+execution. By including this package in your program during development and
+testing, you can identify code that loses buffers right when it's added and
+most easily fixed, rather than as part of a crisis debugging push when the
+problem is identified much later in the testing cycle (or even worse, when the
+code is in the hands of a customer). When program testing is complete, simply
+recompiling with different flags removes SMARTALLOC from your program,
+permitting it to run without speed or storage penalties.
+
+In addition to detecting orphaned buffers, SMARTALLOC also helps to find other
+common problems in management of dynamic storage including storing before the
+start or beyond the end of an allocated buffer, referencing data through a
+pointer to a previously released buffer, attempting to release a buffer twice
+or releasing storage not obtained from the allocator, and assuming the initial
+contents of storage allocated by functions that do not guarantee a known
+value. SMARTALLOC's checking does not usually add a large amount of overhead
+to a program (except for programs which use {\tt realloc()} extensively; see
+below). SMARTALLOC focuses on proper storage management rather than internal
+consistency of the heap as checked by the malloc\_debug facility available on
+some systems. SMARTALLOC does not conflict with malloc\_debug and both may be
+used together, if you wish. SMARTALLOC makes no assumptions regarding the
+internal structure of the heap and thus should be compatible with any C
+language implementation of the standard memory allocation functions.
+
+\subsection{ Installing SMARTALLOC}
+\index{SMARTALLOC!Installing }
+\index{Installing SMARTALLOC }
+\addcontentsline{toc}{subsection}{Installing SMARTALLOC}
+
+SMARTALLOC is provided as a Zipped archive,
+\elink{smartall.zip}{http://www.fourmilab.ch/smartall/smartall.zip}; see the
+download instructions below.
+
+To install SMARTALLOC in your program, simply add the statement:
+
+to every C program file which calls any of the memory allocation functions
+({\tt malloc}, {\tt calloc}, {\tt free}, etc.). SMARTALLOC must be used for
+all memory allocation with a program, so include file for your entire program,
+if you have such a thing. Next, define the symbol SMARTALLOC in the
+compilation before the inclusion of smartall.h. I usually do this by having my
+Makefile add the ``{\tt -DSMARTALLOC}'' option to the C compiler for
+non-production builds. You can define the symbol manually, if you prefer, by
+adding the statement:
+
+{\tt \#define SMARTALLOC}
+
+At the point where your program is all done and ready to relinquish control to
+the operating system, add the call:
+
+{\tt \ \ \ \ \ \ \ \ sm\_dump(}{\it datadump}{\tt );}
+
+where {\it datadump} specifies whether the contents of orphaned buffers are to
+be dumped in addition printing to their size and place of allocation. The data
+are dumped only if {\it datadump} is nonzero, so most programs will normally
+use ``{\tt sm\_dump(0);}''. If a mysterious orphaned buffer appears that can't
+be identified from the information this prints about it, replace the statement
+with ``{\tt sm\_dump(1)};''. Usually the dump of the buffer's data will
+furnish the additional clues you need to excavate and extirpate the elusive
+error that left the buffer allocated.
+
+Finally, add the files ``smartall.h'' and ``smartall.c'' from this release to
+your source directory, make dependencies, and linker input. You needn't make
+inclusion of smartall.c in your link optional; if compiled with SMARTALLOC not
+defined it generates no code, so you may always include it knowing it will
+waste no storage in production builds. Now when you run your program, if it
+leaves any buffers around when it's done, each will be reported by {\tt
+sm\_dump()} on stderr as follows:
+
+\footnotesize
+\begin{verbatim}
+Orphaned buffer: 120 bytes allocated at line 50 of gutshot.c
+\end{verbatim}
+\normalsize
+
+\subsection{ Squelching a SMARTALLOC}
+\index{SMARTALLOC!Squelching a }
+\index{Squelching a SMARTALLOC }
+\addcontentsline{toc}{subsection}{Squelching a SMARTALLOC}
+
+Usually, when you first install SMARTALLOC in an existing program you'll find
+it nattering about lots of orphaned buffers. Some of these turn out to be
+legitimate errors, but some are storage allocated during program
+initialisation that, while dynamically allocated, is logically static storage
+not intended to be released. Of course, you can get rid of the complaints
+about these buffers by adding code to release them, but by doing so you're
+adding unnecessary complexity and code size to your program just to silence
+the nattering of a SMARTALLOC, so an escape hatch is provided to eliminate the
+need to release these buffers.
+
+Normally all storage allocated with the functions {\tt malloc()}, {\tt
+calloc()}, and {\tt realloc()} is monitored by SMARTALLOC. If you make the
+function call:
+
+\footnotesize
+\begin{verbatim}
+ sm_static(1);
+\end{verbatim}
+\normalsize
+
+you declare that subsequent storage allocated by {\tt malloc()}, {\tt
+calloc()}, and {\tt realloc()} should not be considered orphaned if found to
+be allocated when {\tt sm\_dump()} is called. I use a call on ``{\tt
+sm\_static(1);}'' before I allocate things like program configuration tables
+so I don't have to add code to release them at end of program time. After
+allocating unmonitored data this way, be sure to add a call to:
+
+\footnotesize
+\begin{verbatim}
+ sm_static(0);
+\end{verbatim}
+\normalsize
+
+to resume normal monitoring of buffer allocations. Buffers allocated while
+{\tt sm\_static(1}) is in effect are not checked for having been orphaned but
+all the other safeguards provided by SMARTALLOC remain in effect. You may
+release such buffers, if you like; but you don't have to.
+
+\subsection{ Living with Libraries}
+\index{Libraries!Living with }
+\index{Living with Libraries }
+\addcontentsline{toc}{subsection}{Living with Libraries}
+
+Some library functions for which source code is unavailable may gratuitously
+allocate and return buffers that contain their results, or require you to pass
+them buffers which they subsequently release. If you have source code for the
+library, by far the best approach is to simply install SMARTALLOC in it,
+particularly since this kind of ill-structured dynamic storage management is
+the source of so many storage leaks. Without source code, however, there's no
+option but to provide a way to bypass SMARTALLOC for the buffers the library
+allocates and/or releases with the standard system functions.
+
+For each function {\it xxx} redefined by SMARTALLOC, a corresponding routine
+named ``{\tt actually}{\it xxx}'' is furnished which provides direct access to
+the underlying system function, as follows:
+
+\begin{quote}
+
+\begin{longtable}{ll}
+\multicolumn{1}{l }{\bf Standard function } & \multicolumn{1}{l }{\bf Direct
+access function } \\
+{{\tt malloc(}{\it size}{\tt )} } & {{\tt actuallymalloc(}{\it size}{\tt )}
+} \\
+{{\tt calloc(}{\it nelem}{\tt ,} {\it elsize}{\tt )} } & {{\tt
+actuallycalloc(}{\it nelem}, {\it elsize}{\tt )} } \\
+{{\tt realloc(}{\it ptr}{\tt ,} {\it size}{\tt )} } & {{\tt
+actuallyrealloc(}{\it ptr}, {\it size}{\tt )} } \\
+{{\tt free(}{\it ptr}{\tt )} } & {{\tt actuallyfree(}{\it ptr}{\tt )} }
+
+\end{longtable}
+
+\end{quote}
+
+For example, suppose there exists a system library function named ``{\tt
+getimage()}'' which reads a raster image file and returns the address of a
+buffer containing it. Since the library routine allocates the image directly
+with {\tt malloc()}, you can't use SMARTALLOC's {\tt free()}, as that call
+expects information placed in the buffer by SMARTALLOC's special version of
+{\tt malloc()}, and hence would report an error. To release the buffer you
+should call {\tt actuallyfree()}, as in this code fragment:
+
+\footnotesize
+\begin{verbatim}
+ struct image *ibuf = getimage("ratpack.img");
+ display_on_screen(ibuf);
+ actuallyfree(ibuf);
+\end{verbatim}
+\normalsize
+
+Conversely, suppose we are to call a library function, ``{\tt putimage()}'',
+which writes an image buffer into a file and then releases the buffer with
+{\tt free()}. Since the system {\tt free()} is being called, we can't pass a
+buffer allocated by SMARTALLOC's allocation routines, as it contains special
+information that the system {\tt free()} doesn't expect to be there. The
+following code uses {\tt actuallymalloc()} to obtain the buffer passed to such
+a routine.
+
+\footnotesize
+\begin{verbatim}
+ struct image *obuf =
+ (struct image *) actuallymalloc(sizeof(struct image));
+ dump_screen_to_image(obuf);
+ putimage("scrdump.img", obuf); /* putimage() releases obuf */
+\end{verbatim}
+\normalsize
+
+It's unlikely you'll need any of the ``actually'' calls except under very odd
+circumstances (in four products and three years, I've only needed them once),
+but they're there for the rare occasions that demand them. Don't use them to
+subvert the error checking of SMARTALLOC; if you want to disable orphaned
+buffer detection, use the {\tt sm\_static(1)} mechanism described above. That
+way you don't forfeit all the other advantages of SMARTALLOC as you do when
+using {\tt actuallymalloc()} and {\tt actuallyfree()}.
+
+\subsection{ SMARTALLOC Details}
+\index{SMARTALLOC Details }
+\index{Details!SMARTALLOC }
+\addcontentsline{toc}{subsection}{SMARTALLOC Details}
+
+When you include ``smartall.h'' and define SMARTALLOC, the following standard
+system library functions are redefined with the \#define mechanism to call
+corresponding functions within smartall.c instead. (For details of the
+redefinitions, please refer to smartall.h.)
+
+\footnotesize
+\begin{verbatim}
+ void *malloc(size_t size)
+ void *calloc(size_t nelem, size_t elsize)
+ void *realloc(void *ptr, size_t size)
+ void free(void *ptr)
+ void cfree(void *ptr)
+\end{verbatim}
+\normalsize
+
+{\tt cfree()} is a historical artifact identical to {\tt free()}.
+
+In addition to allocating storage in the same way as the standard library
+functions, the SMARTALLOC versions expand the buffers they allocate to include
+information that identifies where each buffer was allocated and to chain all
+allocated buffers together. When a buffer is released, it is removed from the
+allocated buffer chain. A call on {\tt sm\_dump()} is able, by scanning the
+chain of allocated buffers, to find all orphaned buffers. Buffers allocated
+while {\tt sm\_static(1)} is in effect are specially flagged so that, despite
+appearing on the allocated buffer chain, {\tt sm\_dump()} will not deem them
+orphans.
+
+When a buffer is allocated by {\tt malloc()} or expanded with {\tt realloc()},
+all bytes of newly allocated storage are set to the hexadecimal value 0x55
+(alternating one and zero bits). Note that for {\tt realloc()} this applies
+only to the bytes added at the end of buffer; the original contents of the
+buffer are not modified. Initializing allocated storage to a distinctive
+nonzero pattern is intended to catch code that erroneously assumes newly
+allocated buffers are cleared to zero; in fact their contents are random. The
+{\tt calloc()} function, defined as returning a buffer cleared to zero,
+continues to zero its buffers under SMARTALLOC.
+
+Buffers obtained with the SMARTALLOC functions contain a special sentinel byte
+at the end of the user data area. This byte is set to a special key value
+based upon the buffer's memory address. When the buffer is released, the key
+is tested and if it has been overwritten an assertion in the {\tt free}
+function will fail. This catches incorrect program code that stores beyond the
+storage allocated for the buffer. At {\tt free()} time the queue links are
+also validated and an assertion failure will occur if the program has
+destroyed them by storing before the start of the allocated storage.
+
+In addition, when a buffer is released with {\tt free()}, its contents are
+immediately destroyed by overwriting them with the hexadecimal pattern 0xAA
+(alternating bits, the one's complement of the initial value pattern). This
+will usually trip up code that keeps a pointer to a buffer that's been freed
+and later attempts to reference data within the released buffer. Incredibly,
+this is {\it legal} in the standard Unix memory allocation package, which
+permits programs to free() buffers, then raise them from the grave with {\tt
+realloc()}. Such program ``logic'' should be fixed, not accommodated, and
+SMARTALLOC brooks no such Lazarus buffer`` nonsense.
+
+Some C libraries allow a zero size argument in calls to {\tt malloc()}. Since
+this is far more likely to indicate a program error than a defensible
+programming stratagem, SMARTALLOC disallows it with an assertion.
+
+When the standard library {\tt realloc()} function is called to expand a
+buffer, it attempts to expand the buffer in place if possible, moving it only
+if necessary. Because SMARTALLOC must place its own private storage in the
+buffer and also to aid in error detection, its version of {\tt realloc()}
+always moves and copies the buffer except in the trivial case where the size
+of the buffer is not being changed. By forcing the buffer to move on every
+call and destroying the contents of the old buffer when it is released,
+SMARTALLOC traps programs which keep pointers into a buffer across a call on
+{\tt realloc()} which may move it. This strategy may prove very costly to
+programs which make extensive use of {\tt realloc()}. If this proves to be a
+problem, such programs may wish to use {\tt actuallymalloc()}, {\tt
+actuallyrealloc()}, and {\tt actuallyfree()} for such frequently-adjusted
+buffers, trading error detection for performance. Although not specified in
+the System V Interface Definition, many C library implementations of {\tt
+realloc()} permit an old buffer argument of NULL, causing {\tt realloc()} to
+allocate a new buffer. The SMARTALLOC version permits this.
+
+\subsection{ When SMARTALLOC is Disabled}
+\index{When SMARTALLOC is Disabled }
+\index{Disabled!When SMARTALLOC is }
+\addcontentsline{toc}{subsection}{When SMARTALLOC is Disabled}
+
+When SMARTALLOC is disabled by compiling a program with the symbol SMARTALLOC
+not defined, calls on the functions otherwise redefined by SMARTALLOC go
+directly to the system functions. In addition, compile-time definitions
+translate calls on the ''{\tt actually}...{\tt ()}`` functions into the
+corresponding library calls; ''{\tt actuallymalloc(100)}``, for example,
+compiles into ''{\tt malloc(100)}``. The two special SMARTALLOC functions,
+{\tt sm\_dump()} and {\tt sm\_static()}, are defined to generate no code
+(hence the null statement). Finally, if SMARTALLOC is not defined, compilation
+of the file smartall.c generates no code or data at all, effectively removing
+it from the program even if named in the link instructions.
+
+Thus, except for unusual circumstances, a program that works with SMARTALLOC
+defined for testing should require no changes when built without it for
+production release.
+
+\subsection{ The {\tt alloc()} Function}
+\index{Function!alloc }
+\index{Alloc() Function }
+\addcontentsline{toc}{subsection}{alloc() Function}
+
+Many programs I've worked on use very few direct calls to {\tt malloc()},
+using the identically declared {\tt alloc()} function instead. Alloc detects
+out-of-memory conditions and aborts, removing the need for error checking on
+every call of {\tt malloc()} (and the temptation to skip checking for
+out-of-memory).
+
+As a convenience, SMARTALLOC supplies a compatible version of {\tt alloc()} in
+the file alloc.c, with its definition in the file alloc.h. This version of
+{\tt alloc()} is sensitive to the definition of SMARTALLOC and cooperates with
+SMARTALLOC's orphaned buffer detection. In addition, when SMARTALLOC is
+defined and {\tt alloc()} detects an out of memory condition, it takes
+advantage of the SMARTALLOC diagnostic information to identify the file and
+line number of the call on {\tt alloc()} that failed.
+
+\subsection{ Overlays and Underhandedness}
+\index{Underhandedness!Overlays and }
+\index{Overlays and Underhandedness }
+\addcontentsline{toc}{subsection}{Overlays and Underhandedness}
+
+String constants in the C language are considered to be static arrays of
+characters accessed through a pointer constant. The arrays are potentially
+writable even though their pointer is a constant. SMARTALLOC uses the
+compile-time definition {\tt ./smartall.wml} to obtain the name of the file in
+which a call on buffer allocation was performed. Rather than reserve space in
+a buffer to save this information, SMARTALLOC simply stores the pointer to the
+compiled-in text of the file name. This works fine as long as the program does
+not overlay its data among modules. If data are overlayed, the area of memory
+which contained the file name at the time it was saved in the buffer may
+contain something else entirely when {\tt sm\_dump()} gets around to using the
+pointer to edit the file name which allocated the buffer.
+
+If you want to use SMARTALLOC in a program with overlayed data, you'll have to
+modify smartall.c to either copy the file name to a fixed-length field added
+to the {\tt abufhead} structure, or else allocate storage with {\tt malloc()},
+copy the file name there, and set the {\tt abfname} pointer to that buffer,
+then remember to release the buffer in {\tt sm\_free}. Either of these
+approaches are wasteful of storage and time, and should be considered only if
+there is no alternative. Since most initial debugging is done in non-overlayed
+environments, the restrictions on SMARTALLOC with data overlaying may never
+prove a problem. Note that conventional overlaying of code, by far the most
+common form of overlaying, poses no problems for SMARTALLOC; you need only be
+concerned if you're using exotic tools for data overlaying on MS-DOS or other
+address-space-challenged systems.
+
+Since a C language ''constant`` string can actually be written into, most C
+compilers generate a unique copy of each string used in a module, even if the
+same constant string appears many times. In modules that contain many calls on
+allocation functions, this results in substantial wasted storage for the
+strings that identify the file name. If your compiler permits optimization of
+multiple occurrences of constant strings, enabling this mode will eliminate
+the overhead for these strings. Of course, it's up to you to make sure
+choosing this compiler mode won't wreak havoc on some other part of your
+program.

+
+SMARTALLOC is not intended to be a panacea for storage management problems,
+nor is it universally applicable or effective; it's another weapon in the
+arsenal of the defensive professional programmer attempting to create reliable
+products. It represents the current state of evolution of expedient debug code
+which has been used in several commercial software products which have,
+collectively, sold more than third of a million copies in the retail market,
+and can be expected to continue to develop through time as it is applied to
+ever more demanding projects.
+
+The version of SMARTALLOC here has been tested on a Sun SPARCStation, Silicon
+Graphics Indigo2, and on MS-DOS using both Borland and Microsoft C. Moving
+from compiler to compiler requires the usual small changes to resolve disputes
+about prototyping of functions, whether the type returned by buffer allocation
+is {\tt char\ *} or {\tt void\ *}, and so forth, but following those changes

+\addcontentsline{toc}{section}{Storage Daemon Design}
+
+This chapter is intended to be a technical discussion of the Storage daemon
+services and as such is not targeted at end users but rather at developers and
+system administrators that want or need to know more of the working details of
+{\bf Bacula}.
+
+This document is somewhat out of date.
+
+\section{SD Design Introduction}
+\index{Introduction!SD Design }

+\addcontentsline{toc}{section}{SD Design Introduction}
+
+The Bacula Storage daemon provides storage resources to a Bacula installation.
+An individual Storage daemon is associated with a physical permanent storage
+device (for example, a tape drive, CD writer, tape changer or jukebox, etc.),
+and may employ auxiliary storage resources (such as space on a hard disk file
+system) to increase performance and/or optimize use of the permanent storage
+medium.
+
+Any number of storage daemons may be run on a given machine; each associated
+with an individual storage device connected to it, and BACULA operations may
+employ storage daemons on any number of hosts connected by a network, local or
+remote. The ability to employ remote storage daemons (with appropriate
+security measures) permits automatic off-site backup, possibly to publicly
+available backup repositories.
+
+\section{SD Development Outline}

+\addcontentsline{toc}{section}{SD Development Outline}
+
+In order to provide a high performance backup and restore solution that scales
+to very large capacity devices and networks, the storage daemon must be able
+to extract as much performance from the storage device and network with which
+it interacts. In order to accomplish this, storage daemons will eventually
+have to sacrifice simplicity and painless portability in favor of techniques
+which improve performance. My goal in designing the storage daemon protocol
+and developing the initial prototype storage daemon is to provide for these
+additions in the future, while implementing an initial storage daemon which is
+very simple and portable to almost any POSIX-like environment. This original
+storage daemon (and its evolved descendants) can serve as a portable solution
+for non-demanding backup requirements (such as single servers of modest size,
+individual machines, or small local networks), while serving as the starting
+point for development of higher performance configurable derivatives which use
+techniques such as POSIX threads, shared memory, asynchronous I/O, buffering
+to high-speed intermediate media, and support for tape changers and jukeboxes.

+\index{SD Connections and Sessions }
+\addcontentsline{toc}{section}{SD Connections and Sessions}
+
+A client connects to a storage server by initiating a conventional TCP
+connection. The storage server accepts the connection unless its maximum
+number of connections has been reached or the specified host is not granted
+access to the storage server. Once a connection has been opened, the client
+may make any number of Query requests, and/or initiate (if permitted), one or
+more Append sessions (which transmit data to be stored by the storage daemon)
+and/or Read sessions (which retrieve data from the storage daemon).
+
+Most requests and replies sent across the connection are simple ASCII strings,
+with status replies prefixed by a four digit status code for easier parsing.
+Binary data appear in blocks stored and retrieved from the storage. Any
+request may result in a single-line status reply of ``{\tt 3201\ Notification\
+pending}'', which indicates the client must send a ``Query notification''
+request to retrieve one or more notifications posted to it. Once the
+notifications have been returned, the client may then resubmit the request
+which resulted in the 3201 status.
+
+The following descriptions omit common error codes, yet to be defined, which
+can occur from most or many requests due to events like media errors,
+restarting of the storage daemon, etc. These details will be filled in, along
+with a comprehensive list of status codes along with which requests can
+produce them in an update to this document.

+\begin{description}
+
+\item [{append open session = \lt{}JobId\gt{} [ \lt{}Password\gt{} ] }]
+ \index{SPAN class }
+ A data append session is opened with the Job ID given by {\it JobId} with
+client password (if required) given by {\it Password}. If the session is
+successfully opened, a status of {\tt 3000\ OK} is returned with a ``{\tt
+ticket\ =\ }{\it number}'' reply used to identify subsequent messages in the
+session. If too many sessions are open, or a conflicting session (for
+example, a read in progress when simultaneous read and append sessions are
+not permitted), a status of ``{\tt 3502\ Volume\ busy}'' is returned. If no
+volume is mounted, or the volume mounted cannot be appended to, a status of
+``{\tt 3503\ Volume\ not\ mounted}'' is returned.
+
+\item [append data = \lt{}ticket-number\gt{} ]
+ \index{SPAN class }
+ If the append data is accepted, a status of {\tt 3000\ OK data address =
+\lt{}IPaddress\gt{} port = \lt{}port\gt{}} is returned, where the {\tt
+IPaddress} and {\tt port} specify the IP address and port number of the data
+channel. Error status codes are {\tt 3504\ Invalid\ ticket\ number} and {\tt
+3505\ Session\ aborted}, the latter of which indicates the entire append
+session has failed due to a daemon or media error.
+
+Once the File daemon has established the connection to the data channel
+opened by the Storage daemon, it will transfer a header packet followed by
+any number of data packets. The header packet is of the form:
+
+{\tt \lt{}file-index\gt{} \lt{}stream-id\gt{} \lt{}info\gt{}}
+
+The details are specified in the
+\ilink{Daemon Protocol}{_ChapterStart2} section of this
+document.
+
+\item [*append abort session = \lt{}ticket-number\gt{} ]
+ \index{SPAN class }
+ The open append session with ticket {\it ticket-number} is aborted; any blocks
+not yet written to permanent media are discarded. Subsequent attempts to
+append data to the session will receive an error status of {\tt 3505\
+Session\ aborted}.
+
+\item [append end session = \lt{}ticket-number\gt{} ]
+ \index{SPAN class }
+ The open append session with ticket {\it ticket-number} is marked complete; no

+possible.
+
+\item [append close session = \lt{}ticket-number\gt{} ]
+ \index{SPAN class }
+ The append session with ticket {\it ticket} is closed. This message does not
+receive an {\tt 3000\ OK} reply until all of the content of the session are
+stored on permanent media, at which time said reply is given, followed by a
+list of volumes, from first to last, which contain blocks from the session,
+along with the first and last file and block on each containing session data
+and the volume session key identifying data from that session in lines with
+the following format:
+
+{\tt {\tt Volume = }\lt{}Volume-id\gt{} \lt{}start-file\gt{}

+\section{SD Data Structures}
+\index{SD Data Structures}
+\addcontentsline{toc}{section}{SD Data Structures}
+
+In the Storage daemon, there is a Device resource (i.e. from conf file)
+that describes each physical device. When the physical device is used it
+is controled by the DEVICE structure (defined in dev.h), and typically
+refered to as dev in the C++ code. Anyone writing or reading a physical
+device must ultimately get a lock on the DEVICE structure -- this controls
+the device. However, multiple Jobs (defined by a JCR structure src/jcr.h)
+can be writing a physical DEVICE at the same time (of course they are
+sequenced by locking the DEVICE structure). There are a lot of job
+dependent "device" variables that may be different for each Job such as
+spooling (one job may spool and another may not, and when a job is
+spooling, it must have an i/o packet open, each job has its own record and
+block structures, ...), so there is a device control record or DCR that is
+the primary way of interfacing to the physical device. The DCR contains
+all the job specific data as well as a pointer to the Device resource
+(DEVRES structure) and the physical DEVICE structure.
+
+Now if a job is writing to two devices (it could be writing two separate
+streams to the same device), it must have two DCRs. Today, the code only
+permits one. This won't be hard to change, but it is new code.
+
+Today three jobs (threads), two physical devices each job
+ writes to only one device:
+
+\begin{verbatim}
+ Job1 -> DCR1 -> DEVICE1
+ Job2 -> DCR2 -> DEVICE1
+ Job3 -> DCR3 -> DEVICE2
+\end{verbatim}
+
+To be implemented three jobs, three physical devices, but
+ job1 is writing simultaneously to three devices:
+
+\begin{verbatim}
+ Job1 -> DCR1 -> DEVICE1
+ -> DCR4 -> DEVICE2
+ -> DCR5 -> DEVICE3
+ Job2 -> DCR2 -> DEVICE1
+ Job3 -> DCR3 -> DEVICE2
+
+ Job = job control record
+ DCR = Job contorl data for a specific device
+ DEVICE = Device only control data

+\section{Introduction to TLS}
+\index{TLS Introduction}
+\index{Introduction!TLS}
+\addcontentsline{toc}{section}{TLS Introduction}
+
+This patch includes all the back-end code necessary to add complete TLS
+data encryption support to Bacula. In addition, support for TLS in
+Console/Director communications has been added as a proof of concept.
+Adding support for the remaining daemons will be straight-forward.
+Supported features of this patchset include:
+
+\begin{itemize}
+\item Client/Server TLS Requirement Negotiation
+\item TLSv1 Connections with Server and Client Certificate
+Validation
+\item Forward Secrecy Support via Diffie-Hellman Ephemeral Keying
+\end{itemize}
+
+This document will refer to both ``server'' and ``client'' contexts. These
+terms refer to the accepting and initiating peer, respectively.
+
+Diffie-Hellman anonymous ciphers are not supported by this patchset. The
+use of DH anonymous ciphers increases the code complexity and places
+explicit trust upon the two-way Cram-MD5 implementation. Cram-MD5 is
+subject to known plaintext attacks, and is should be considered
+considerably less secure than PKI certificate-based authentication.
+
+Appropriate autoconf macros have been added to detect and use OpenSSL. Two
+additional preprocessor defines have been added: \emph{HAVE\_TLS} and
+\emph{HAVE\_OPENSSL}. All changes not specific to OpenSSL rely on
+\emph{HAVE\_TLS}. OpenSSL-specific code is constrained to
+\emph{src/lib/tls.c} to facilitate the support of alternative TLS
+implementations.
+
+\section{New Configuration Directives}
+\index{TLS Configuration Directives}
+\index{Directives!TLS Configuration}
+\addcontentsline{toc}{section}{New Configuration Directives}
+
+Additional configuration directives have been added to both the Console and
+Director resources. These new directives are defined as follows:
+
+\begin{itemize}
+\item \underline{TLS Enable} \emph{(yes/no)}
+Enable TLS support.
+
+\item \underline{TLS Require} \emph{(yes/no)}
+Require TLS connections.
+
+\item \underline{TLS Certificate} \emph{(path)}
+Path to PEM encoded TLS certificate. Used as either a client or server
+certificate.
+
+\item \underline{TLS Key} \emph{(path)}
+Path to PEM encoded TLS private key. Must correspond with the TLS
+certificate.
+
+\item \underline{TLS Verify Peer} \emph{(yes/no)}
+Verify peer certificate. Instructs server to request and verify the
+client's x509 certificate. Any client certificate signed by a known-CA
+will be accepted unless the TLS Allowed CN configuration directive is used.
+Not valid in a client context.
+
+\item \underline{TLS Allowed CN} \emph{(string list)}
+Common name attribute of allowed peer certificates. If directive is
+specified, all client certificates will be verified against this list.
+This directive may be specified more than once. Not valid in a client
+context.
+
+\item \underline{TLS CA Certificate File} \emph{(path)}
+Path to PEM encoded TLS CA certificate(s). Multiple certificates are
+permitted in the file. One of \emph{TLS CA Certificate File} or \emph{TLS
+CA Certificate Dir} are required in a server context if \underline{TLS
+Verify Peer} is also specified, and are always required in a client
+context.
+
+\item \underline{TLS CA Certificate Dir} \emph{(path)}
+Path to TLS CA certificate directory. In the current implementation,
+certificates must be stored PEM encoded with OpenSSL-compatible hashes.
+One of \emph{TLS CA Certificate File} or \emph{TLS CA Certificate Dir} are
+required in a server context if \emph{TLS Verify Peer} is also specified,
+and are always required in a client context.
+
+\item \underline{TLS DH File} \emph{(path)}
+Path to PEM encoded Diffie-Hellman parameter file. If this directive is
+specified, DH ephemeral keying will be enabled, allowing for forward
+secrecy of communications. This directive is only valid within a server
+context. To generate the parameter file, you may use openssl:
+\footnotesize
+\begin{verbatim}
+openssl dhparam -out dh1024.pem -5 1024

+\chapter{Autochanger Resource}
+\index[sd]{Autochanger Resource}
+\index[sd]{Resource!Autochanger}
+
+The Autochanger resource supports single or multiple drive
+autochangers by grouping one or more Device resources
+into one unit called an autochanger in Bacula (often referred to
+as a "tape library" by autochanger manufacturers).
+
+If you have an Autochanger, and you want it to function correctly,
+you {\bf must} have an Autochanger resource in your Storage
+conf file, and your Director's Storage directives that want to
+use an Autochanger {\bf must} refer to the Autochanger resource name.
+In previous versions of Bacula, the Director's Storage directives
+referred directly to Device resources that were autochangers.
+In version 1.38.0 and later, referring directly to Device resources
+will not work for Autochangers.
+
+\begin{description}
+\item [Name = \lt{}Autochanger-Name\gt{}]
+ \index[sd]{Name}
+ Specifies the Name of the Autochanger. This name is used in the
+ Director's Storage definition to refer to the autochanger. This
+ directive is required.
+
+\item [Device = \lt{}Device-name1, device-name2, ...\gt{}]
+ Specifies the names of the Device resource or resources that correspond
+ to the autochanger drive. If you have a multiple drive autochanger, you
+ must specify multiple Device names, each one referring to a separate
+ Device resource that contains a Drive Index specification that
+ corresponds to the drive number base zero. You may specify multiple
+ device names on a single line separated by commas, and/or you may
+ specify multiple Device directives. This directive is required.
+
+\item [Changer Device = {\it name-string}]
+ \index[sd]{Changer Device}
+ The specified {\bf name-string} gives the system file name of the autochanger
+ device name. If specified in this resource, the Changer Device name
+ is not needed in the Device resource. If it is specified in the Device
+ resource (see above), it will take precedence over one specified in
+ the Autochanger resource.
+
+\item [Changer Command = {\it name-string}]
+ \index[sd]{Changer Command }
+ The {\bf name-string} specifies an external program to be called that will
+ automatically change volumes as required by {\bf Bacula}. Most frequently,
+ you will specify the Bacula supplied {\bf mtx-changer} script as follows.
+ If it is specified here, it need not be specified in the Device
+ resource. If it is also specified in the Device resource, it will take
+ precedence over the one specified in the Autochanger resource.
+
+\end{description}
+
+The following is an example of a valid Autochanger resource definition:
+
+\footnotesize
+\begin{verbatim}
+Autochanger {
+ Name = "DDS-4-changer"
+ Device = DDS-4-1, DDS-4-2, DDS-4-3
+ Changer Device = /dev/sg0
+ Changer Command = "/etc/bacula/mtx-changer %c %o %S %a %d"
+}
+Device {
+ Name = "DDS-4-1"
+ Drive Index = 0
+ Autochanger = yes
+ ...
+}
+Device {
+ Name = "DDS-4-2"
+ Drive Index = 1
+ Autochanger = yes
+ ...
+Device {
+ Name = "DDS-4-3"
+ Drive Index = 2
+ Autochanger = yes
+ Autoselect = no
+ ...
+}
+\end{verbatim}
+\normalsize
+
+Please note that it is important to include the {\bf Autochanger = yes} directive
+in each Device definition that belongs to an Autochanger. A device definition
+should not belong to more than one Autochanger resource. Also, your Device
+directive in the Storage resource of the Director's conf file should have
+the Autochanger's resource name rather than a name of one of the Devices.
+
+If you have a drive that physically belongs to an Autochanger but you don't want
+to have it automatically used when Bacula references the Autochanger for backups,
+for example, you want to reserve it for restores, you can add the directive:
+
+\footnotesize
+\begin{verbatim}
+Autoselect = no
+\end{verbatim}
+\normalsize
+
+to the Device resource for that drive. In that case, Bacula will not automatically
+select that drive when accessing the Autochanger. You can, still use the drive
+by referencing it by the Device name directly rather than the Autochanger name. An example
+of such a definition is shown above for the Device DDS-4-3, which will not be
+selected when the name DDS-4-changer is used in a Storage definition, but will
+be used if DDS-4-3 is used.

+\chapter{Customizing the Configuration Files}
+\label{ConfigureChapter}
+\index[general]{Files!Customizing the Configuration }
+\index[general]{Customizing the Configuration Files }
+
+When each of the Bacula programs starts, it reads a configuration file
+specified on the command line or the default {\bf bacula-dir.conf}, {\bf
+bacula-fd.conf}, {\bf bacula-sd.conf}, or {\bf console.conf} for the Director
+daemon, the File daemon, the Storage daemon, and the Console program
+respectively.
+
+Each service (Director, Client, Storage, Console) has its own configuration
+file containing a set of Resource definitions. These resources are very
+similar from one service to another, but may contain different directives
+(records) depending on the service. For example, in the Director's resource
+file, the {\bf Director} resource defines the name of the Director, a number
+of global Director parameters and his password. In the File daemon
+configuration file, the {\bf Director} resource specifies which Directors are
+permitted to use the File daemon.
+
+Before running Bacula for the first time, you must customize the configuration
+files for each daemon. Default configuration files will have been created by
+the installation process, but you will need to modify them to correspond to
+your system. An overall view of the resources can be seen in the following:
+
+\addcontentsline{lof}{figure}{Bacula Objects}
+\includegraphics{\idir bacula-objects.eps}
+\label{ResFormat}
+
+\section{Character Sets}
+\index[general]{Character Sets}
+Bacula is designed to handle most character sets of the world,
+US ASCII, German, French, Chinese, ... However, it does this by
+encoding everything in UTF-8, and it expects all configuration files
+(including those read on Win32 machines) to be in UTF-8 format.
+UTF-8 is typically the default on Linux machines, but not on all
+Unix machines, nor on Windows, so you must take some care to ensure
+that your locale is set properly before starting Bacula.
+
+To ensure that Bacula configuration files can be correctly read including
+foreign characters the {bf LANG} environment variable
+must end in {\bf .UTF-8}. An full example is {\bf en\_US.UTF-8}. The
+exact syntax may vary a bit from OS to OS, and exactly how you define
+it will also vary. On most newer Win32 machines, you can use {\bf notepad}
+to edit the conf files, then choose output encoding UTF-8.
+
+Bacula assumes that all filenames are in UTF-8 format on Linux and
+Unix machines. On Win32 they are in Unicode (UTF-16), and will
+be automatically converted to UTF-8 format.
+
+\section{Resource Directive Format}
+\index[general]{Resource Directive Format }
+\index[general]{Format!Resource Directive }
+
+Although, you won't need to know the details of all the directives a basic
+knowledge of Bacula resource directives is essential. Each directive contained
+within the resource (within the braces) is composed of a keyword followed by
+an equal sign (=) followed by one or more values. The keywords must be one of
+the known Bacula resource record keywords, and it may be composed of upper or
+lower case characters and spaces.
+
+Each resource definition MUST contain a Name directive, and may optionally
+contain a Description directive. The Name directive is used to
+uniquely identify the resource. The Description directive is (will be) used
+during display of the Resource to provide easier human recognition. For
+example:
+
+\footnotesize
+\begin{verbatim}
+Director {
+ Name = "MyDir"
+ Description = "Main Bacula Director"
+ WorkingDirectory = "$HOME/bacula/bin/working"
+}
+\end{verbatim}
+\normalsize
+
+Defines the Director resource with the name "MyDir" and a working directory
+\$HOME/bacula/bin/working. In general, if you want spaces in a name to the
+right of the first equal sign (=), you must enclose that name within double
+quotes. Otherwise quotes are not generally necessary because once defined,
+quoted strings and unquoted strings are all equal.
+
+\label{Comments}
+\subsection{Comments}
+\index[general]{Comments}
+
+When reading the configuration file, blank lines are ignored and everything
+after a hash sign (\#) until the end of the line is taken to be a comment. A
+semicolon (;) is a logical end of line, and anything after the semicolon is
+considered as the next statement. If a statement appears on a line by itself,
+a semicolon is not necessary to terminate it, so generally in the examples in
+this manual, you will not see many semicolons.
+\label{Case1}
+
+\subsection{Upper and Lower Case and Spaces}
+\index[general]{Spaces!Upper/Lower Case}
+\index[general]{Upper and Lower Case and Spaces}
+
+Case (upper/lower) and spaces are totally ignored in the resource directive
+keywords (the part before the equal sign).
+
+Within the keyword (i.e. before the equal sign), spaces are not significant.
+Thus the keywords: {\bf name}, {\bf Name}, and {\bf N a m e} are all
+identical.
+
+Spaces after the equal sign and before the first character of the value are
+ignored.
+
+In general, spaces within a value are significant (not ignored), and if the
+value is a name, you must enclose the name in double quotes for the spaces to
+be accepted. Names may contain up to 127 characters. Currently, a name may
+contain any ASCII character. Within a quoted string, any character following a
+backslash (\textbackslash{}) is taken as itself (handy for inserting
+backslashes and double quotes (")).
+
+Please note, however, that Bacula resource names as well as certain other
+names (e.g. Volume names) must contain only letters (including ISO accented
+letters), numbers, and a few special characters (space, underscore, ...).
+All other characters and punctuation are invalid.
+
+\label{Includes}
+\subsection{Including other Configuration Files}
+\index[general]{Including other Configuration Files }
+\index[general]{Files!Including other Configuration }
+\index[general]{Using @ to include other files}
+\index[general]{@{\bf filename}}
+
+If you wish to break your configuration file into smaller pieces, you can do
+so by including other files using the syntax @{\bf filename} where {\bf
+filename} is the full path and filename of another file. The @filename
+specification can be given anywhere a primitive token would appear.
+
+\label{DataTypes}
+\subsection{Recognized Primitive Data Types}
+\index[general]{Types!Recognized Primitive Data }
+\index[general]{Recognized Primitive Data Types }
+
+When parsing the resource directives, Bacula classifies the data according to
+the types listed below. The first time you read this, it may appear a bit
+overwhelming, but in reality, it is all pretty logical and straightforward.
+
+\begin{description}
+
+\item [name]
+ \index[fd]{name}
+ A keyword or name consisting of alphanumeric characters, including the
+hyphen, underscore, and dollar characters. The first character of a {\bf
+name} must be a letter. A name has a maximum length currently set to 127
+bytes. Typically keywords appear on the left side of an equal (i.e. they are
+Bacula keywords -- i.e. Resource names or directive names). Keywords may not
+be quoted.
+
+\item [name-string]
+ \index[fd]{name-string}
+ A name-string is similar to a name, except that the name may be quoted and
+can thus contain additional characters including spaces. Name strings are
+limited to 127 characters in length. Name strings are typically used on the
+right side of an equal (i.e. they are values to be associated with a keyword).
+
+
+\item [string]
+ \index[fd]{string}
+ A quoted string containing virtually any character including spaces, or a
+non-quoted string. A string may be of any length. Strings are typically
+values that correspond to filenames, directories, or system command names. A
+backslash (\textbackslash{}) turns the next character into itself, so to
+include a double quote in a string, you precede the double quote with a
+backslash. Likewise to include a backslash.
+
+\item [directory]
+ \index[dir]{directory}
+ A directory is either a quoted or non-quoted string. A directory will be
+passed to your standard shell for expansion when it is scanned. Thus
+constructs such as {\bf \$HOME} are interpreted to be their correct values.
+
+\item [password]
+ \index[dir]{password}
+ This is a Bacula password and it is stored internally in MD5 hashed format.
+
+\item [integer]
+ \index[dir]{integer}
+ A 32 bit integer value. It may be positive or negative.
+
+\item [positive integer]
+ \index[dir]{positive integer }
+ A 32 bit positive integer value.
+
+\item [long integer]
+ \index[dir]{long integer}
+ A 64 bit integer value. Typically these are values such as bytes that can
+exceed 4 billion and thus require a 64 bit value.
+
+\item [yes|no]
+ \index[dir]{yes or no }
+ Either a {\bf yes} or a {\bf no}.
+
+\label{Size1}
+\item [size]
+\index[dir]{size}
+A size specified as bytes. Typically, this is a floating point scientific
+input format followed by an optional modifier. The floating point input is
+stored as a 64 bit integer value. If a modifier is present, it must
+immediately follow the value with no intervening spaces. The following
+modifiers are permitted:
+
+\begin{description}
+\item [k]
+ 1,024 (kilobytes)
+
+\item [kb]
+ 1,000 (kilobytes)
+
+\item [m]
+ 1,048,576 (megabytes)
+
+\item [mb]
+ 1,000,000 (megabytes)
+
+\item [g]
+ 1,073,741,824 (gigabytes)
+
+\item [gb]
+ 1,000,000,000 (gigabytes)
+\end{description}
+
+\label{Time}
+\item [time]
+\index[dir]{time}
+A time or duration specified in seconds. The time is stored internally as
+a 64 bit integer value, but it is specified in two parts: a number part and
+a modifier part. The number can be an integer or a floating point number.
+If it is entered in floating point notation, it will be rounded to the
+nearest integer. The modifier is mandatory and follows the number part,
+either with or without intervening spaces. The following modifiers are
+permitted:
+
+\begin{description}
+
+\item [seconds]
+ \index[dir]{seconds}
+ seconds
+
+\item [minutes]
+ \index[dir]{minutes}
+ minutes (60 seconds)
+
+\item [hours]
+ \index[dir]{hours }
+ hours (3600 seconds)
+
+\item [days]
+ \index[dir]{days}
+ days (3600*24 seconds)
+
+\item [weeks]
+ \index[dir]{weeks}
+ weeks (3600*24*7 seconds)
+
+\item [months]
+ \index[dir]{months }
+ months (3600*24*30 seconds)
+
+\item [quarters]
+ \index[dir]{quarters }
+ quarters (3600*24*91 seconds)
+
+\item [years]
+ \index[dir]{years }
+ years (3600*24*365 seconds)
+\end{description}
+
+Any abbreviation of these modifiers is also permitted (i.e. {\bf seconds}
+may be specified as {\bf sec} or {\bf s}). A specification of {\bf m} will
+be taken as months.
+
+The specification of a time may have as many number/modifier parts as you
+wish. For example:
+
+\footnotesize
+\begin{verbatim}
+1 week 2 days 3 hours 10 mins
+1 month 2 days 30 sec
+
+\end{verbatim}
+\normalsize
+
+are valid date specifications.
+
+\end{description}
+
+\label{ResTypes}
+\section{Resource Types}
+\index[general]{Types!Resource }
+\index[general]{Resource Types }
+
+The following table lists all current Bacula resource types. It shows what
+resources must be defined for each service (daemon). The default configuration
+files will already contain at least one example of each permitted resource, so
+you need not worry about creating all these kinds of resources from scratch.
+
+\addcontentsline{lot}{table}{Resource Types}

+\section{Names, Passwords and Authorization}
+\label{Names}
+\index[general]{Authorization!Names Passwords and }
+\index[general]{Names, Passwords and Authorization }
+\index[general]{Passwords}
+
+In order for one daemon to contact another daemon, it must authorize itself
+with a password. In most cases, the password corresponds to a particular name,
+so both the name and the password must match to be authorized. Passwords are
+plain text, any text. They are not generated by any special process; just
+use random text.
+
+The default configuration files are automatically defined for correct
+authorization with random passwords. If you add to or modify these files, you
+will need to take care to keep them consistent.
+
+Here is sort of a picture of what names/passwords in which files/Resources
+must match up:
+
+\includegraphics{\idir Conf-Diagram.eps}
+
+In the left column, you will find the Director, Storage, and Client resources,
+with their names and passwords -- these are all in {\bf bacula-dir.conf}. In
+the right column are where the corresponding values should be found in the
+Console, Storage daemon (SD), and File daemon (FD) configuration files.
+
+Please note that the Address, {\bf fd-sd}, that appears in the Storage
+resource of the Director, preceded with and asterisk in the above example, is
+passed to the File daemon in symbolic form. The File daemon then resolves it
+to an IP address. For this reason, you must use either an IP address or a
+fully qualified name. A name such as {\bf localhost}, not being a fully
+qualified name, will resolve in the File daemon to the localhost of the File
+daemon, which is most likely not what is desired. The password used for the
+File daemon to authorize with the Storage daemon is a temporary password
+unique to each Job created by the daemons and is not specified in any .conf
+file.
+
+\section{Detailed Information for each Daemon}
+\index[general]{Detailed Information for each Daemon }
+\index[general]{Daemon!Detailed Information for each }
+
+The details of each Resource and the directives permitted therein are
+described in the following chapters.
+
+The following configuration files must be defined:
+
+\begin{itemize}
+\item
+ \ilink{Console}{ConsoleConfChapter} -- to define the resources for
+ the Console program (user interface to the Director). It defines which
+Directors are available so that you may interact with them.
+\item
+ \ilink{Director}{DirectorChapter} -- to define the resources
+ necessary for the Director. You define all the Clients and Storage daemons
+that you use in this configuration file.
+\item
+ \ilink{Client}{FiledConfChapter} -- to define the resources for
+ each client to be backed up. That is, you will have a separate Client
+resource file on each machine that runs a File daemon.
+\item
+ \ilink{Storage}{StoredConfChapter} -- to define the resources to
+ be used by each Storage daemon. Normally, you will have a single Storage
+daemon that controls your tape drive or tape drives. However, if you have
+tape drives on several machines, you will have at least one Storage daemon
+per machine.

+\chapter{Console Configuration}
+\label{ConsoleConfChapter}
+\index[general]{Configuration!Console}
+\index[general]{Console Configuration}
+
+\section{General}
+\index[general]{General}
+
+The Console configuration file is the simplest of all the configuration files,
+and in general, you should not need to change it except for the password. It
+simply contains the information necessary to contact the Director or
+Directors.
+
+For a general discussion of the syntax of configuration files and their
+resources including the data types recognized by {\bf Bacula}, please see
+the \ilink{Configuration}{ConfigureChapter} chapter of this manual.
+
+The following Console Resource definition must be defined:
+
+\section{The Director Resource}
+\label{DirectorResource3}
+\index[general]{Director Resource}
+\index[general]{Resource!Director}
+
+The Director resource defines the attributes of the Director running on the
+network. You may have multiple Director resource specifications in a single
+Console configuration file. If you have more than one, you will be prompted to
+choose one when you start the {\bf Console} program.
+
+\begin{description}
+\item [Director]
+ \index[console]{Director}
+ Start of the Director directives.
+
+\item [Name = \lt{}name\gt{}]
+ \index[console]{Name}
+ The director name used to select among different Directors, otherwise, this
+ name is not used.
+
+\item [DIRPort = \lt{}port-number\gt{}]
+ \index[dir]{DIRPort}
+ Specify the port to use to connect to the Director. This value will most
+ likely already be set to the value you specified on the {\bf
+ \verb:--:with-base-port} option of the {\bf ./configure} command. This port must be
+ identical to the {\bf DIRport} specified in the {\bf Director} resource of
+ the \ilink{Director's configuration}{DirectorChapter} file. The
+ default is 9101 so this directive is not normally specified.
+
+\item [Address = \lt{}address\gt{}]
+ \index[dir]{Address}
+ Where the address is a host name, a fully qualified domain name, or a network
+ address used to connect to the Director.
+
+\item [Password = \lt{}password\gt{}]
+ \index[dir]{Password}
+ Where the password is the password needed for the Director to accept the
+ Console connection. This password must be identical to the {\bf Password}
+ specified in the {\bf Director} resource of the
+ \ilink{Director's configuration}{DirectorChapter} file. This
+ directive is required.
+\end{description}
+
+An actual example might be:
+
+\footnotesize
+\begin{verbatim}
+Director {
+ Name = HeadMan
+ address = rufus.cats.com
+ password = xyz1erploit
+}
+\end{verbatim}
+\normalsize
+
+\section{The ConsoleFont Resource}
+\index[general]{Resource!ConsoleFont}
+\index[general]{ConsoleFont Resource}
+
+The ConsoleFont resource is available only in the GNOME version of the
+console. It permits you to define the font that you want used to display in
+the main listing window.
+
+\begin{description}
+
+\item [ConsoleFont]
+ \index[console]{ConsoleFont}
+ Start of the ConsoleFont directives.
+
+\item [Name = \lt{}name\gt{}]
+ \index[console]{Name}
+ The name of the font.
+
+\item [Font = \lt{}Pango Font Name\gt{}]
+ \index[console]{Font}
+ The string value given here defines the desired font. It is specified in the
+ Pango format. For example, the default specification is:
+
+\footnotesize
+\begin{verbatim}
+Font = "LucidaTypewriter 9"
+\end{verbatim}
+\normalsize
+
+\end{description}
+
+Thanks to Phil Stracchino for providing the code for this feature.
+
+An different example might be:
+
+\footnotesize
+\begin{verbatim}
+ConsoleFont {
+ Name = Default
+ Font = "Monospace 10"
+}
+\end{verbatim}
+\normalsize
+
+\section{The Console Resource}
+\label{ConsoleResource}
+\index[general]{Console Resource}
+\index[general]{Resource!Console}
+
+As of Bacula version 1.33 and higher, there are three different kinds of
+consoles, which the administrator or user can use to interact with the
+Director. These three kinds of consoles comprise three different security
+levels.
+
+\begin{itemize}
+\item The first console type is an {\bf anonymous} or {\bf default} console,
+ which has full privileges. There is no console resource necessary for this
+ type since the password is specified in the Director resource. This is the
+ kind of console that was initially implemented in versions prior to 1.33 and
+ remains valid. Typically you would use it only for administrators.
+
+\item The second type of console, and new to version 1.33 and higher is a
+ "named" or "restricted" console defined within a Console resource in
+ both the Director's configuration file and in the Console's
+ configuration file. Both the names and the passwords in these two
+ entries must match much as is the case for Client programs.
+
+ This second type of console begins with absolutely no privileges except
+ those explicitly specified in the Director's Console resource. Note,
+ the definition of what these restricted consoles can do is determined
+ by the Director's conf file.
+
+ Thus you may define within the Director's conf file multiple Consoles
+ with different names and passwords, sort of like multiple users, each
+ with different privileges. As a default, these consoles can do
+ absolutely nothing -- no commands what so ever. You give them
+ privileges or rather access to commands and resources by specifying
+ access control lists in the Director's Console resource. This gives the
+ administrator fine grained control over what particular consoles (or
+ users) can do.
+
+\item The third type of console is similar to the above mentioned
+ restricted console in that it requires a Console resource definition in
+ both the Director and the Console. In addition, if the console name,
+ provided on the {\bf Name =} directive, is the same as a Client name,
+ the user of that console is permitted to use the {\bf SetIP} command to
+ change the Address directive in the Director's client resource to the IP
+ address of the Console. This permits portables or other machines using
+ DHCP (non-fixed IP addresses) to "notify" the Director of their current
+ IP address.
+
+\end{itemize}
+
+The Console resource is optional and need not be specified. However, if it is
+specified, you can use ACLs (Access Control Lists) in the Director's
+configuration file to restrict the particular console (or user) to see only
+information pertaining to his jobs or client machine.
+
+You may specify as many Console resources in the console's conf file. If
+you do so, generally the first Console resource will be used. However, if
+you have multiple Director resources (i.e. you want to connect to different
+directors), you can bind one of your Console resources to a particular
+Director resource, and thus when you choose a particular Director, the
+appropriate Console configuration resource will be used. See the "Director"
+directive in the Console resource described below for more information.
+
+Note, the Console resource is optional, but can be useful for
+restricted consoles as noted above.
+
+\begin{description}
+\item [Console]
+ \index[console]{Console}
+ Start of the Console resource.
+
+\item [Name = \lt{}name\gt{}]
+ \index[console]{Name}
+ The Console name used to allow a restricted console to change
+ its IP address using the SetIP command. The SetIP command must
+ also be defined in the Director's conf CommandACL list.
+
+
+\item [Password = \lt{}password\gt{}]
+ \index[console]{Password}
+ If this password is supplied, then the password specified in the
+ Director resource of you Console conf will be ignored. See below
+ for more details.
+
+\item [Director = \lt{}director-resource-name\gt{}]
+ If this directive is specified, this Console resource will be
+ used by bconsole when that particular director is selected
+ when first starting bconsole. I.e. it binds a particular console
+ resource with its name and password to a particular director.
+
+\item [Heartbeat Interval = \lt{}time-interval\gt{}]
+ \index[console]{Heartbeat Interval}
+ \index[console]{Directive!Heartbeat}
+ This directive is optional and if specified will cause the Console to
+ set a keepalive interval (heartbeat) in seconds on each of the sockets
+ to communicate with the Director. It is implemented only on systems
+ (Linux, ...) that provide the {\bf setsockopt} TCP\_KEEPIDLE function.
+ The default value is zero, which means no change is made to the socket.
+
+\end{description}
+
+
+The following configuration files were supplied by Phil Stracchino. For
+example, if we define the following in the user's bconsole.conf file (or
+perhaps the bwx-console.conf file):
+
+\footnotesize
+\begin{verbatim}
+Director {
+ Name = MyDirector
+ DIRport = 9101
+ Address = myserver
+ Password = "XXXXXXXXXXX" # no, really. this is not obfuscation.
+}
+
+
+Console {
+ Name = restricted-user
+ Password = "UntrustedUser"
+}
+\end{verbatim}
+\normalsize
+
+Where the Password in the Director section is deliberately incorrect, and the
+Console resource is given a name, in this case {\bf restricted-user}. Then
+in the Director's bacula-dir.conf file (not directly accessible by the user),
+we define:
+
+\footnotesize
+\begin{verbatim}
+Console {
+ Name = restricted-user
+ Password = "UntrustedUser"
+ JobACL = "Restricted Client Save"
+ ClientACL = restricted-client
+ StorageACL = main-storage
+ ScheduleACL = *all*
+ PoolACL = *all*
+ FileSetACL = "Restricted Client's FileSet"
+ CatalogACL = DefaultCatalog
+ CommandACL = run
+}
+\end{verbatim}
+\normalsize
+
+the user logging into the Director from his Console will get logged in as {\bf
+restricted-user}, and he will only be able to see or access a Job with the
+name {\bf Restricted Client Save} a Client with the name {\bf
+restricted-client}, a Storage device {\bf main-storage}, any Schedule or Pool,
+a FileSet named {\bf Restricted Client's FileSet}, a Catalog named {\bf
+DefaultCatalog}, and the only command he can use in the Console is the {\bf
+run} command. In other words, this user is rather limited in what he can see
+and do with Bacula.
+
+The following is an example of a bconsole conf file that can access
+several Directors and has different Consoles depending on the director:
+
+\footnotesize
+\begin{verbatim}
+Director {
+ Name = MyDirector
+ DIRport = 9101
+ Address = myserver
+ Password = "XXXXXXXXXXX" # no, really. this is not obfuscation.
+}
+
+Director {
+ Name = SecondDirector
+ DIRport = 9101
+ Address = secondserver
+ Password = "XXXXXXXXXXX" # no, really. this is not obfuscation.
+}
+
+Console {
+ Name = restricted-user
+ Password = "UntrustedUser"
+ Director = MyDirector
+}
+
+Console {
+ Name = restricted-user
+ Password = "A different UntrustedUser"
+ Director = SecondDirector
+}
+\end{verbatim}
+\normalsize
+
+The second Director referenced at "secondserver" might look
+like the following:
+
+\footnotesize
+\begin{verbatim}
+Console {
+ Name = restricted-user
+ Password = "A different UntrustedUser"
+ JobACL = "Restricted Client Save"
+ ClientACL = restricted-client
+ StorageACL = second-storage
+ ScheduleACL = *all*
+ PoolACL = *all*
+ FileSetACL = "Restricted Client's FileSet"
+ CatalogACL = RestrictedCatalog
+ CommandACL = run, restore
+ WhereACL = "/"
+}

+\chapter{Critical Items to Implement Before Production}
+\label{CriticalChapter}
+\index[general]{Production!Critical Items to Implement Before }
+\index[general]{Critical Items to Implement Before Production }
+
+We recommend you take your time before implementing a production a Bacula
+backup system since Bacula is a rather complex program, and if you make a
+mistake, you may suddenly find that you cannot restore your files in case
+of a disaster. This is especially true if you have not previously used a
+major backup product.
+
+If you follow the instructions in this chapter, you will have covered most of
+the major problems that can occur. It goes without saying that if you ever
+find that we have left out an important point, please inform us, so
+that we can document it to the benefit of everyone.
+
+\label{Critical}
+\section{Critical Items}
+\index[general]{Critical Items }
+\index[general]{Items!Critical }
+
+The following assumes that you have installed Bacula, you more or less
+understand it, you have at least worked through the tutorial or have
+equivalent experience, and that you have set up a basic production
+configuration. If you haven't done the above, please do so and then come back
+here. The following is a sort of checklist that points with perhaps a brief
+explanation of why you should do it. In most cases, you will find the
+details elsewhere in the manual. The order is more or less the order you
+would use in setting up a production system (if you already are in
+production, use the checklist anyway).
+
+\begin{itemize}
+\item Test your tape drive for compatibility with Bacula by using the test
+ command in the \ilink{btape}{btape} program.
+\item Better than doing the above is to walk through the nine steps in the
+ \ilink{Tape Testing}{TapeTestingChapter} chapter of the manual. It
+ may take you a bit of time, but it will eliminate surprises.
+\item Test the end of tape handling of your tape drive by using the
+ fill command in the \ilink{btape}{btape} program.
+\item If you are using a Linux 2.4 kernel, make sure that /lib/tls is disabled. Bacula
+ does not work with this library. See the second point under
+ \ilink{ Supported Operating Systems.}{SupportedOSes}
+\item Do at least one restore of files. If you backup multiple OS types
+ (Linux, Solaris, HP, MacOS, FreeBSD, Win32, ...),
+ restore files from each system type. The
+ \ilink{Restoring Files}{RestoreChapter} chapter shows you how.
+\item Write a bootstrap file to a separate system for each backup job. The
+ Write Bootstrap directive is described in the
+ \ilink{Director Configuration}{writebootstrap} chapter of the
+ manual, and more details are available in the
+ \ilink{Bootstrap File}{BootstrapChapter} chapter. Also, the default
+ bacula-dir.conf comes with a Write Bootstrap directive defined. This allows
+ you to recover the state of your system as of the last backup.
+\item Backup your catalog. An example of this is found in the default
+ bacula-dir.conf file. The backup script is installed by default and
+ should handle any database, though you may want to make your own local
+ modifications. See also \ilink{Backing Up Your Bacula Database -
+ Security Considerations }{BackingUpBaculaSecurityConsiderations} for more
+ information.
+\item Write a bootstrap file for the catalog. An example of this is found in
+ the default bacula-dir.conf file. This will allow you to quickly restore your
+ catalog in the event it is wiped out -- otherwise it is many excruciating
+ hours of work.
+\item Make a copy of the bacula-dir.conf, bacula-sd.conf, and
+ bacula-fd.conf files that you are using on your server. Put it in a safe
+ place (on another machine) as these files can be difficult to
+ reconstruct if your server dies.
+\item Make a Bacula Rescue CDROM! See the
+ \ilink{Disaster Recovery Using a Bacula Rescue
+ CDROM}{RescueChapter} chapter. It is trivial to make such a CDROM,
+ and it can make system recovery in the event of a lost hard disk infinitely
+ easier.
+\item Bacula assumes all filenames are in UTF-8 format. This is important
+ when saving the filenames to the catalog. For Win32 machine, Bacula will
+ automatically convert from Unicode to UTF-8, but on Unix, Linux, *BSD,
+ and MacOS X machines, you must explicitly ensure that your locale is set
+ properly. Typically this means that the {bf LANG} environment variable
+ must end in {\bf .UTF-8}. An full example is {\bf en\_US.UTF-8}. The
+ exact syntax may vary a bit from OS to OS, and exactly how you define it
+ will also vary.
+
+ On most modern Win32 machines, you can edit the conf files with {\bf
+ notepad} and choose output encoding UTF-8.
+\end{itemize}
+
+\section{Recommended Items}
+\index[general]{Items!Recommended }
+\index[general]{Recommended Items }
+
+Although these items may not be critical, they are recommended and will help
+you avoid problems.
+
+\begin{itemize}
+\item Read the \ilink{Quick Start Guide to Bacula}{QuickStartChapter}
+\item After installing and experimenting with Bacula, read and work carefully
+ through the examples in the
+ \ilink{Tutorial}{TutorialChapter} chapter of this manual.
+\item Learn what each of the \ilink{Bacula Utility Programs}{_UtilityChapter}
+ does.
+\item Set up reasonable retention periods so that your catalog does not grow
+ to be too big. See the following three chapters:\\
+ \ilink{Recycling your Volumes}{RecyclingChapter},\\
+ \ilink{Basic Volume Management}{DiskChapter},\\
+ \ilink{Using Pools to Manage Volumes}{PoolsChapter}.
+\item Perform a bare metal recovery using the Bacula Rescue CDROM. See the
+ \ilink{Disaster Recovery Using a Bacula Rescue CDROM}{RescueChapter}
+ chapter.
+\end{itemize}
+
+If you absolutely must implement a system where you write a different
+tape each night and take it offsite in the morning. We recommend that you do
+several things:
+\begin{itemize}
+\item Write a bootstrap file of your backed up data and a bootstrap file
+ of your catalog backup to a floppy disk or a CDROM, and take that with
+ the tape. If this is not possible, try to write those files to another
+ computer or offsite computer, or send them as email to a friend. If none
+ of that is possible, at least print the bootstrap files and take that
+ offsite with the tape. Having the bootstrap files will make recovery
+ much easier.
+\item It is better not to force Bacula to load a particular tape each day.
+ Instead, let Bacula choose the tape. If you need to know what tape to
+ mount, you can print a list of recycled and appendable tapes daily, and
+ select any tape from that list. Bacula may propose a particular tape
+ for use that it considers optimal, but it will accept any valid tape
+ from the correct pool.
+\end{itemize}

+\label{DirectorChapter}
+\index[general]{Director!Configuring the}
+\index[general]{Configuring the Director}
+
+Of all the configuration files needed to run {\bf Bacula}, the Director's is
+the most complicated, and the one that you will need to modify the most often
+as you add clients or modify the FileSets.
+
+For a general discussion of configuration files and resources including the
+data types recognized by {\bf Bacula}. Please see the
+\ilink{Configuration}{ConfigureChapter} chapter of this manual.
+
+\section{Director Resource Types}
+\index[general]{Types!Director Resource}
+\index[general]{Director Resource Types}
+
+Director resource type may be one of the following:
+
+Job, JobDefs, Client, Storage, Catalog, Schedule, FileSet, Pool, Director, or
+Messages. We present them here in the most logical order for defining them:
+
+Note, everything revolves around a job and is tied to a job in one
+way or another.
+
+\begin{itemize}
+\item
+ \ilink{Director}{DirectorResource4} -- to define the Director's
+ name and its access password used for authenticating the Console program.
+ Only a single Director resource definition may appear in the Director's
+ configuration file. If you have either {\bf /dev/random} or {\bf bc} on your
+ machine, Bacula will generate a random password during the configuration
+ process, otherwise it will be left blank.
+\item
+ \ilink{Job}{JobResource} -- to define the backup/restore Jobs
+ and to tie together the Client, FileSet and Schedule resources to be used
+ for each Job. Normally, you will Jobs of different names corresponding
+ to each client (i.e. one Job per client, but a different one with a different name
+ for each client).
+\item
+ \ilink{JobDefs}{JobDefsResource} -- optional resource for
+ providing defaults for Job resources.
+\item
+ \ilink{Schedule}{ScheduleResource} -- to define when a Job is to
+ be automatically run by {\bf Bacula's} internal scheduler. You
+ may have any number of Schedules, but each job will reference only
+ one.
+\item
+ \ilink{FileSet}{FileSetResource} -- to define the set of files
+ to be backed up for each Client. You may have any number of
+ FileSets but each Job will reference only one.
+\item
+ \ilink{Client}{ClientResource2} -- to define what Client is to be
+ backed up. You will generally have multiple Client definitions. Each
+ Job will reference only a single client.
+\item
+ \ilink{Storage}{StorageResource2} -- to define on what physical
+ device the Volumes should be mounted. You may have one or
+ more Storage definitions.
+\item
+ \ilink{Pool}{PoolResource} -- to define the pool of Volumes
+ that can be used for a particular Job. Most people use a
+ single default Pool. However, if you have a large number
+ of clients or volumes, you may want to have multiple Pools.
+ Pools allow you to restrict a Job (or a Client) to use
+ only a particular set of Volumes.
+\item
+ \ilink{Catalog}{CatalogResource} -- to define in what database to
+ keep the list of files and the Volume names where they are backed up.
+ Most people only use a single catalog. However, if you want to
+ scale the Director to many clients, multiple catalogs can be helpful.
+ Multiple catalogs require a bit more management because in general
+ you must know what catalog contains what data. Currently, all
+ Pools are defined in each catalog. This restriction will be removed
+ in a later release.
+\item
+ \ilink{Messages}{MessagesChapter} -- to define where error and
+ information messages are to be sent or logged. You may define
+ multiple different message resources and hence direct particular
+ classes of messages to different users or locations (files, ...).
+\end{itemize}
+
+\section{The Director Resource}
+\label{DirectorResource4}
+\index[general]{Director Resource}
+\index[general]{Resource!Director}
+
+The Director resource defines the attributes of the Directors running on the
+network. In the current implementation, there is only a single Director
+resource, but the final design will contain multiple Directors to maintain
+index and media database redundancy.
+
+\begin{description}
+
+\item [Director]
+ \index[dir]{Director}
+ Start of the Director resource. One and only one director resource must be
+supplied.
+
+\item [Name = \lt{}name\gt{}]
+ \index[dir]{Name}
+ \index[dir]{Directive!Name}
+ The director name used by the system administrator. This directive is
+required.
+
+\item [Description = \lt{}text\gt{}]
+ \index[dir]{Description}
+ \index[dir]{Directive!Description}
+ The text field contains a description of the Director that will be displayed
+in the graphical user interface. This directive is optional.
+
+\item [Password = \lt{}UA-password\gt{}]
+ \index[dir]{Password}
+ \index[dir]{Directive!Password}
+ Specifies the password that must be supplied for the default Bacula
+ Console to be authorized. The same password must appear in the {\bf
+ Director} resource of the Console configuration file. For added
+ security, the password is never passed across the network but instead a
+ challenge response hash code created with the password. This directive
+ is required. If you have either {\bf /dev/random} or {\bf bc} on your
+ machine, Bacula will generate a random password during the configuration
+ process, otherwise it will be left blank and you must manually supply
+ it.
+
+ The password is plain text. It is not generated through any special
+ process but as noted above, it is better to use random text for
+ security reasons.
+
+\item [Messages = \lt{}Messages-resource-name\gt{}]
+ \index[dir]{Messages}
+ \index[dir]{Directive!Messages}
+ The messages resource specifies where to deliver Director messages that are
+ not associated with a specific Job. Most messages are specific to a job and
+ will be directed to the Messages resource specified by the job. However,
+ there are a few messages that can occur when no job is running. This
+ directive is required.
+
+\item [Working Directory = \lt{}Directory\gt{}]
+ \index[dir]{Working Directory}
+ \index[dir]{Directive!Working Directory}
+ This directive is mandatory and specifies a directory in which the Director
+ may put its status files. This directory should be used only by Bacula but
+ may be shared by other Bacula daemons. However, please note, if this
+ directory is shared with other Bacula daemons (the File daemon and Storage
+ daemon), you must ensure that the {\bf Name} given to each daemon is
+ unique so that the temporary filenames used do not collide. By default
+ the Bacula configure process creates unique daemon names by postfixing them
+ with -dir, -fd, and -sd. Standard shell expansion of the {\bf
+ Directory} is done when the configuration file is read so that values such
+ as {\bf \$HOME} will be properly expanded. This directive is required.
+ The working directory specified must already exist and be
+ readable and writable by the Bacula daemon referencing it.
+
+ If you have specified a Director user and/or a Director group on your
+ ./configure line with {\bf {-}{-}with-dir-user} and/or
+ {\bf {-}{-}with-dir-group} the Working Directory owner and group will
+ be set to those values.
+
+\item [Pid Directory = \lt{}Directory\gt{}]
+ \index[dir]{Pid Directory}
+ \index[dir]{Directive!Pid Directory}
+ This directive is mandatory and specifies a directory in which the Director
+ may put its process Id file. The process Id file is used to shutdown
+ Bacula and to prevent multiple copies of Bacula from running simultaneously.
+ Standard shell expansion of the {\bf Directory} is done when the
+ configuration file is read so that values such as {\bf \$HOME} will be
+ properly expanded.
+
+ The PID directory specified must already exist and be
+ readable and writable by the Bacula daemon referencing it
+
+ Typically on Linux systems, you will set this to: {\bf /var/run}. If you are
+ not installing Bacula in the system directories, you can use the {\bf Working
+ Directory} as defined above. This directive is required.
+
+\item [Scripts Directory = \lt{}Directory\gt{}]
+ \index[dir]{Scripts Directory}
+ \index[dir]{Directive!Scripts Directory}
+ This directive is optional and, if defined, specifies a directory in
+ which the Director will look for the Python startup script {\bf
+ DirStartup.py}. This directory may be shared by other Bacula daemons.
+ Standard shell expansion of the directory is done when the configuration
+ file is read so that values such as {\bf \$HOME} will be properly
+ expanded.
+
+\item [QueryFile = \lt{}Path\gt{}]
+ \index[dir]{QueryFile}
+ \index[dir]{Directive!QueryFile}
+ This directive is mandatory and specifies a directory and file in which
+ the Director can find the canned SQL statements for the {\bf Query}
+ command of the Console. Standard shell expansion of the {\bf Path} is
+ done when the configuration file is read so that values such as {\bf
+ \$HOME} will be properly expanded. This directive is required.
+
+\item [Heartbeat Interval = \lt{}time-interval\gt{}]
+ \index[dir]{Heartbeat Interval}
+ \index[dir]{Directive!Heartbeat}
+ This directive is optional and if specified will cause the Director to
+ set a keepalive interval (heartbeat) in seconds on each of the sockets
+ it opens for the Client resource. This value will override any
+ specified at the Director level. It is implemented only on systems
+ (Linux, ...) that provide the {\bf setsockopt} TCP\_KEEPIDLE function.
+ The default value is zero, which means no change is made to the socket.
+
+
+\label{DirMaxConJobs}
+\item [Maximum Concurrent Jobs = \lt{}number\gt{}]
+ \index[dir]{Maximum Concurrent Jobs}
+ \index[dir]{Directive!Maximum Concurrent Jobs}
+ \index[general]{Simultaneous Jobs}
+ \index[general]{Concurrent Jobs}
+ where \lt{}number\gt{} is the maximum number of total Director Jobs that
+ should run concurrently. The default is set to 1, but you may set it to a
+ larger number.
+
+ The Volume format becomes more complicated with
+ multiple simultaneous jobs, consequently, restores may take longer if
+ Bacula must sort through interleaved volume blocks from multiple simultaneous
+ jobs. This can be avoided by having each simultaneous job write to
+ a different volume or by using data spooling, which will first spool the data
+ to disk simultaneously, then write one spool file at a time to the volume
+ thus avoiding excessive interleaving of the different job blocks.
+
+\item [FD Connect Timeout = \lt{}time\gt{}]
+ \index[dir]{FD Connect Timeout}
+ \index[dir]{Directive!FD Connect Timeout}
+ where {\bf time} is the time that the Director should continue
+ attempting to contact the File daemon to start a job, and after which
+ the Director will cancel the job. The default is 30 minutes.
+
+\item [SD Connect Timeout = \lt{}time\gt{}]
+ \index[dir]{SD Connect Timeout}
+ \index[dir]{Directive!SD Connect Timeout}
+ where {\bf time} is the time that the Director should continue
+ attempting to contact the Storage daemon to start a job, and after which
+ the Director will cancel the job. The default is 30 minutes.
+
+\item [DirAddresses = \lt{}IP-address-specification\gt{}]
+ \index[dir]{DirAddresses}
+ \index[dir]{Address}
+ \index[general]{Address}
+ \index[dir]{Directive!DirAddresses}
+ Specify the ports and addresses on which the Director daemon will listen
+ for Bacula Console connections. Probably the simplest way to explain
+ this is to show an example:
+
+\footnotesize
+\begin{verbatim}
+ DirAddresses = {
+ ip = { addr = 1.2.3.4; port = 1205;}
+ ipv4 = {
+ addr = 1.2.3.4; port = http;}
+ ipv6 = {
+ addr = 1.2.3.4;
+ port = 1205;
+ }
+ ip = {
+ addr = 1.2.3.4
+ port = 1205
+ }
+ ip = { addr = 1.2.3.4 }
+ ip = { addr = 201:220:222::2 }
+ ip = {
+ addr = bluedot.thun.net
+ }
+}
+\end{verbatim}
+\normalsize
+
+where ip, ip4, ip6, addr, and port are all keywords. Note, that the address
+can be specified as either a dotted quadruple, or IPv6 colon notation, or as
+a symbolic name (only in the ip specification). Also, port can be specified
+as a number or as the mnemonic value from the /etc/services file. If a port
+is not specified, the default will be used. If an ip section is specified,
+the resolution can be made either by IPv4 or IPv6. If ip4 is specified, then
+only IPv4 resolutions will be permitted, and likewise with ip6.
+
+Please note that if you use the DirAddresses directive, you must
+not use either a DirPort or a DirAddress directive in the same
+resource.
+
+\item [DirPort = \lt{}port-number\gt{}]
+ \index[dir]{DirPort}
+ \index[dir]{Directive!DirPort}
+ Specify the port (a positive integer) on which the Director daemon will
+ listen for Bacula Console connections. This same port number must be
+ specified in the Director resource of the Console configuration file. The
+ default is 9101, so normally this directive need not be specified. This
+ directive should not be used if you specify DirAddresses (N.B plural)
+ directive.
+
+\item [DirAddress = \lt{}IP-Address\gt{}]
+ \index[dir]{DirAddress}
+ \index[dir]{Directive!DirAddress}
+ This directive is optional, but if it is specified, it will cause the
+ Director server (for the Console program) to bind to the specified {\bf
+ IP-Address}, which is either a domain name or an IP address specified as a
+ dotted quadruple in string or quoted string format. If this directive is
+ not specified, the Director will bind to any available address (the
+ default). Note, unlike the DirAddresses specification noted above, this
+ directive only permits a single address to be specified. This directive
+ should not be used if you specify a DirAddresses (N.B. plural) directive.
+
+\item [DirSourceAddress = \lt{}IP-Address\gt{}]
+ \index[fd]{DirSourceAddress}
+ \index[fd]{Directive!DirSourceAddress}
+ This record is optional, and if it is specified, it will cause the Director
+ server (when initiating connections to a storage or file daemon) to source
+ its connections from the specified address. Only a single IP address may be
+ specified. If this record is not specified, the Director server will source
+ its outgoing connections according to the system routing table (the default).
+
+\item[Statistics Retention = \lt{}time\gt{}]
+ \index[dir]{StatisticsRetention}
+ \index[dir]{Directive!StatisticsRetention}
+ \label{PruneStatistics}
+
+ The \texttt{Statistics Retention} directive defines the length of time that

+\section{The Job Resource}
+\label{JobResource}
+\index[general]{Resource!Job}
+\index[general]{Job Resource}
+
+The Job resource defines a Job (Backup, Restore, ...) that Bacula must
+perform. Each Job resource definition contains the name of a Client and
+a FileSet to backup, the Schedule for the Job, where the data
+are to be stored, and what media Pool can be used. In effect, each Job
+resource must specify What, Where, How, and When or FileSet, Storage,
+Backup/Restore/Level, and Schedule respectively. Note, the FileSet must
+be specified for a restore job for historical reasons, but it is no longer used.
+
+Only a single type ({\bf Backup}, {\bf Restore}, ...) can be specified for any
+job. If you want to backup multiple FileSets on the same Client or multiple
+Clients, you must define a Job for each one.
+
+Note, you define only a single Job to do the Full, Differential, and
+Incremental backups since the different backup levels are tied together by
+a unique Job name. Normally, you will have only one Job per Client, but
+if a client has a really huge number of files (more than several million),
+you might want to split it into to Jobs each with a different FileSet
+covering only part of the total files.
+
+Multiple Storage daemons are not currently supported for Jobs, so if
+you do want to use multiple storage daemons, you will need to create
+a different Job and ensure that for each Job that the combination of
+Client and FileSet are unique. The Client and FileSet are what Bacula
+uses to restore a client, so if there are multiple Jobs with the same
+Client and FileSet or multiple Storage daemons that are used, the
+restore will not work. This problem can be resolved by defining multiple
+FileSet definitions (the names must be different, but the contents of
+the FileSets may be the same).
+
+
+\begin{description}
+
+\item [Job]
+ \index[dir]{Job}
+ \index[dir]{Directive!Job}
+ Start of the Job resource. At least one Job resource is required.
+
+\item [Name = \lt{}name\gt{}]
+ \index[dir]{Name}
+ \index[dir]{Directive!Name}
+ The Job name. This name can be specified on the {\bf Run} command in the
+ console program to start a job. If the name contains spaces, it must be
+ specified between quotes. It is generally a good idea to give your job the
+ same name as the Client that it will backup. This permits easy
+ identification of jobs.
+
+ When the job actually runs, the unique Job Name will consist of the name you
+ specify here followed by the date and time the job was scheduled for
+ execution. This directive is required.
+
+\item [Enabled = \lt{}yes|no\gt{}]
+ \index[dir]{Enable}
+ \index[dir]{Directive!Enable}
+ This directive allows you to enable or disable automatic execution
+ via the scheduler of a Job.
+
+\item [Type = \lt{}job-type\gt{}]
+ \index[dir]{Type}
+ \index[dir]{Directive!Type}
+ The {\bf Type} directive specifies the Job type, which may be one of the
+ following: {\bf Backup}, {\bf Restore}, {\bf Verify}, or {\bf Admin}. This
+ directive is required. Within a particular Job Type, there are also Levels
+ as discussed in the next item.
+
+\begin{description}
+
+\item [Backup]
+ \index[dir]{Backup}
+ Run a backup Job. Normally you will have at least one Backup job for each
+ client you want to save. Normally, unless you turn off cataloging, most all
+ the important statistics and data concerning files backed up will be placed
+ in the catalog.
+
+\item [Restore]
+ \index[dir]{Restore}
+ Run a restore Job. Normally, you will specify only one Restore job
+ which acts as a sort of prototype that you will modify using the console
+ program in order to perform restores. Although certain basic
+ information from a Restore job is saved in the catalog, it is very
+ minimal compared to the information stored for a Backup job -- for
+ example, no File database entries are generated since no Files are
+ saved.
+
+ {\bf Restore} jobs cannot be
+ automatically started by the scheduler as is the case for Backup, Verify
+ and Admin jobs. To restore files, you must use the {\bf restore} command
+ in the console.
+
+
+\item [Verify]
+ \index[dir]{Verify}
+ Run a verify Job. In general, {\bf verify} jobs permit you to compare the
+ contents of the catalog to the file system, or to what was backed up. In
+ addition, to verifying that a tape that was written can be read, you can
+ also use {\bf verify} as a sort of tripwire intrusion detection.
+
+\item [Admin]
+ \index[dir]{Admin}
+ Run an admin Job. An {\bf Admin} job can be used to periodically run catalog
+ pruning, if you do not want to do it at the end of each {\bf Backup} Job.
+ Although an Admin job is recorded in the catalog, very little data is saved.
+\end{description}
+
+\label{Level}
+
+\item [Level = \lt{}job-level\gt{}]
+\index[dir]{Level}
+\index[dir]{Directive!Level}
+ The Level directive specifies the default Job level to be run. Each
+ different Job Type (Backup, Restore, ...) has a different set of Levels
+ that can be specified. The Level is normally overridden by a different
+ value that is specified in the {\bf Schedule} resource. This directive
+ is not required, but must be specified either by a {\bf Level} directive
+ or as an override specified in the {\bf Schedule} resource.
+
+For a {\bf Backup} Job, the Level may be one of the following:
+
+\begin{description}
+
+\item [Full]
+\index[dir]{Full}
+ When the Level is set to Full all files in the FileSet whether or not
+ they have changed will be backed up.
+
+\item [Incremental]
+ \index[dir]{Incremental}
+ When the Level is set to Incremental all files specified in the FileSet
+ that have changed since the last successful backup of the the same Job
+ using the same FileSet and Client, will be backed up. If the Director
+ cannot find a previous valid Full backup then the job will be upgraded
+ into a Full backup. When the Director looks for a valid backup record
+ in the catalog database, it looks for a previous Job with:
+
+\begin{itemize}
+\item The same Job name.
+\item The same Client name.
+\item The same FileSet (any change to the definition of the FileSet such as
+ adding or deleting a file in the Include or Exclude sections constitutes a
+ different FileSet.
+\item The Job was a Full, Differential, or Incremental backup.
+\item The Job terminated normally (i.e. did not fail or was not canceled).
+\item The Job started no longer ago than {\bf Max Full Age}.
+\end{itemize}
+
+ If all the above conditions do not hold, the Director will upgrade the
+ Incremental to a Full save. Otherwise, the Incremental backup will be
+ performed as requested.
+
+ The File daemon (Client) decides which files to backup for an
+ Incremental backup by comparing start time of the prior Job (Full,
+ Differential, or Incremental) against the time each file was last
+ "modified" (st\_mtime) and the time its attributes were last
+ "changed"(st\_ctime). If the file was modified or its attributes
+ changed on or after this start time, it will then be backed up.
+
+ Some virus scanning software may change st\_ctime while
+ doing the scan. For example, if the virus scanning program attempts to
+ reset the access time (st\_atime), which Bacula does not use, it will
+ cause st\_ctime to change and hence Bacula will backup the file during
+ an Incremental or Differential backup. In the case of Sophos virus
+ scanning, you can prevent it from resetting the access time (st\_atime)
+ and hence changing st\_ctime by using the {\bf \verb:--:no-reset-atime}
+ option. For other software, please see their manual.
+
+ When Bacula does an Incremental backup, all modified files that are
+ still on the system are backed up. However, any file that has been
+ deleted since the last Full backup remains in the Bacula catalog,
+ which means that if between a Full save and the time you do a
+ restore, some files are deleted, those deleted files will also be
+ restored. The deleted files will no longer appear in the catalog
+ after doing another Full save.
+
+ In addition, if you move a directory rather than copy it, the files in
+ it do not have their modification time (st\_mtime) or their attribute
+ change time (st\_ctime) changed. As a consequence, those files will
+ probably not be backed up by an Incremental or Differential backup which
+ depend solely on these time stamps. If you move a directory, and wish
+ it to be properly backed up, it is generally preferable to copy it, then
+ delete the original.
+
+ However, to manage deleted files or directories changes in the
+ catalog during an Incremental backup you can use \texttt{accurate}
+ mode. This is quite memory consuming process. See \ilink{Accurate
+ mode}{accuratemode} for more details.
+
+\item [Differential]
+ \index[dir]{Differential}
+ When the Level is set to Differential
+ all files specified in the FileSet that have changed since the last
+ successful Full backup of the same Job will be backed up.
+ If the Director cannot find a
+ valid previous Full backup for the same Job, FileSet, and Client,
+ backup, then the Differential job will be upgraded into a Full backup.
+ When the Director looks for a valid Full backup record in the catalog
+ database, it looks for a previous Job with:
+
+\begin{itemize}
+\item The same Job name.
+\item The same Client name.
+\item The same FileSet (any change to the definition of the FileSet such as
+ adding or deleting a file in the Include or Exclude sections constitutes a
+ different FileSet.
+\item The Job was a FULL backup.
+\item The Job terminated normally (i.e. did not fail or was not canceled).
+\item The Job started no longer ago than {\bf Max Full Age}.
+\end{itemize}
+
+ If all the above conditions do not hold, the Director will upgrade the
+ Differential to a Full save. Otherwise, the Differential backup will be
+ performed as requested.
+
+ The File daemon (Client) decides which files to backup for a
+ differential backup by comparing the start time of the prior Full backup
+ Job against the time each file was last "modified" (st\_mtime) and the
+ time its attributes were last "changed" (st\_ctime). If the file was
+ modified or its attributes were changed on or after this start time, it
+ will then be backed up. The start time used is displayed after the {\bf
+ Since} on the Job report. In rare cases, using the start time of the
+ prior backup may cause some files to be backed up twice, but it ensures
+ that no change is missed. As with the Incremental option, you should
+ ensure that the clocks on your server and client are synchronized or as
+ close as possible to avoid the possibility of a file being skipped.
+ Note, on versions 1.33 or greater Bacula automatically makes the
+ necessary adjustments to the time between the server and the client so
+ that the times Bacula uses are synchronized.
+
+ When Bacula does a Differential backup, all modified files that are
+ still on the system are backed up. However, any file that has been
+ deleted since the last Full backup remains in the Bacula catalog, which
+ means that if between a Full save and the time you do a restore, some
+ files are deleted, those deleted files will also be restored. The
+ deleted files will no longer appear in the catalog after doing another
+ Full save. However, to remove deleted files from the catalog during a
+ Differential backup is quite a time consuming process and not currently
+ implemented in Bacula. It is, however, a planned future feature.
+
+ As noted above, if you move a directory rather than copy it, the
+ files in it do not have their modification time (st\_mtime) or
+ their attribute change time (st\_ctime) changed. As a
+ consequence, those files will probably not be backed up by an
+ Incremental or Differential backup which depend solely on these
+ time stamps. If you move a directory, and wish it to be
+ properly backed up, it is generally preferable to copy it, then
+ delete the original. Alternatively, you can move the directory, then
+ use the {\bf touch} program to update the timestamps.
+
+%% TODO: merge this with incremental
+ However, to manage deleted files or directories changes in the
+ catalog during an Differential backup you can use \texttt{accurate}
+ mode. This is quite memory consuming process. See \ilink{Accurate
+ mode}{accuratemode} for more details.
+
+ Every once and a while, someone asks why we need Differential
+ backups as long as Incremental backups pickup all changed files.
+ There are possibly many answers to this question, but the one
+ that is the most important for me is that a Differential backup
+ effectively merges
+ all the Incremental and Differential backups since the last Full backup
+ into a single Differential backup. This has two effects: 1. It gives
+ some redundancy since the old backups could be used if the merged backup
+ cannot be read. 2. More importantly, it reduces the number of Volumes
+ that are needed to do a restore effectively eliminating the need to read
+ all the volumes on which the preceding Incremental and Differential
+ backups since the last Full are done.
+
+\end{description}
+
+For a {\bf Restore} Job, no level needs to be specified.
+
+For a {\bf Verify} Job, the Level may be one of the following:
+
+\begin{description}
+
+\item [InitCatalog]
+\index[dir]{InitCatalog}
+ does a scan of the specified {\bf FileSet} and stores the file
+ attributes in the Catalog database. Since no file data is saved, you
+ might ask why you would want to do this. It turns out to be a very
+ simple and easy way to have a {\bf Tripwire} like feature using {\bf
+ Bacula}. In other words, it allows you to save the state of a set of
+ files defined by the {\bf FileSet} and later check to see if those files
+ have been modified or deleted and if any new files have been added.
+ This can be used to detect system intrusion. Typically you would
+ specify a {\bf FileSet} that contains the set of system files that
+ should not change (e.g. /sbin, /boot, /lib, /bin, ...). Normally, you
+ run the {\bf InitCatalog} level verify one time when your system is
+ first setup, and then once again after each modification (upgrade) to
+ your system. Thereafter, when your want to check the state of your
+ system files, you use a {\bf Verify} {\bf level = Catalog}. This
+ compares the results of your {\bf InitCatalog} with the current state of
+ the files.
+
+\item [Catalog]
+\index[dir]{Catalog}
+ Compares the current state of the files against the state previously
+ saved during an {\bf InitCatalog}. Any discrepancies are reported. The
+ items reported are determined by the {\bf verify} options specified on
+ the {\bf Include} directive in the specified {\bf FileSet} (see the {\bf
+ FileSet} resource below for more details). Typically this command will
+ be run once a day (or night) to check for any changes to your system
+ files.
+
+ Please note! If you run two Verify Catalog jobs on the same client at
+ the same time, the results will certainly be incorrect. This is because
+ Verify Catalog modifies the Catalog database while running in order to
+ track new files.
+
+\item [VolumeToCatalog]
+\index[dir]{VolumeToCatalog}
+ This level causes Bacula to read the file attribute data written to the
+ Volume from the last Job. The file attribute data are compared to the
+ values saved in the Catalog database and any differences are reported.
+ This is similar to the {\bf Catalog} level except that instead of
+ comparing the disk file attributes to the catalog database, the
+ attribute data written to the Volume is read and compared to the catalog
+ database. Although the attribute data including the signatures (MD5 or
+ SHA1) are compared, the actual file data is not compared (it is not in
+ the catalog).
+
+ Please note! If you run two Verify VolumeToCatalog jobs on the same
+ client at the same time, the results will certainly be incorrect. This
+ is because the Verify VolumeToCatalog modifies the Catalog database
+ while running.
+
+\item [DiskToCatalog]
+\index[dir]{DiskToCatalog}
+ This level causes Bacula to read the files as they currently are on
+ disk, and to compare the current file attributes with the attributes
+ saved in the catalog from the last backup for the job specified on the
+ {\bf VerifyJob} directive. This level differs from the {\bf Catalog}
+ level described above by the fact that it doesn't compare against a
+ previous Verify job but against a previous backup. When you run this
+ level, you must supply the verify options on your Include statements.
+ Those options determine what attribute fields are compared.
+
+ This command can be very useful if you have disk problems because it
+ will compare the current state of your disk against the last successful
+ backup, which may be several jobs.
+
+ Note, the current implementation (1.32c) does not identify files that
+ have been deleted.
+\end{description}
+
+\item [Accurate = \lt{}yes|no\gt{}]
+\index[dir]{Accurate}
+ In accurate mode, FileDaemon known exactly which files were present
+ after last backup. So it is able to handle deleted or renamed files.
+
+ When restoring a fileset for a specified date (including "most
+ recent"), Bacula is able to give you exactly the files and
+ directories that existed at the time of the last backup prior to
+ that date.
+
+ In this mode, FileDaemon have to keep all files in memory. So you have
+ to check that your memory and swap are sufficent.
+
+ $$ memory = \sum_{i=1}^{n}(strlen(path_i + file_i) + sizeof(CurFile))$$
+
+ For 500.000 files (typical desktop linux system), it will take
+ around 64MB of RAM on your FileDaemon.
+
+\item [Verify Job = \lt{}Job-Resource-Name\gt{}]
+ \index[dir]{Verify Job}
+ \index[dir]{Directive!Verify Job}
+ If you run a verify job without this directive, the last job run will be
+ compared with the catalog, which means that you must immediately follow
+ a backup by a verify command. If you specify a {\bf Verify Job} Bacula
+ will find the last job with that name that ran. This permits you to run
+ all your backups, then run Verify jobs on those that you wish to be
+ verified (most often a {\bf VolumeToCatalog}) so that the tape just
+ written is re-read.
+
+\item [JobDefs = \lt{}JobDefs-Resource-Name\gt{}]
+\index[dir]{JobDefs}
+\index[dir]{Directive!JobDefs}
+ If a JobDefs-Resource-Name is specified, all the values contained in the
+ named JobDefs resource will be used as the defaults for the current Job.
+ Any value that you explicitly define in the current Job resource, will
+ override any defaults specified in the JobDefs resource. The use of
+ this directive permits writing much more compact Job resources where the
+ bulk of the directives are defined in one or more JobDefs. This is
+ particularly useful if you have many similar Jobs but with minor
+ variations such as different Clients. A simple example of the use of
+ JobDefs is provided in the default bacula-dir.conf file.
+
+\item [Bootstrap = \lt{}bootstrap-file\gt{}]
+\index[dir]{Bootstrap}
+\index[dir]{Directive!Bootstrap}
+ The Bootstrap directive specifies a bootstrap file that, if provided,
+ will be used during {\bf Restore} Jobs and is ignored in other Job
+ types. The {\bf bootstrap} file contains the list of tapes to be used
+ in a restore Job as well as which files are to be restored.
+ Specification of this directive is optional, and if specified, it is
+ used only for a restore job. In addition, when running a Restore job
+ from the console, this value can be changed.
+
+ If you use the {\bf Restore} command in the Console program, to start a
+ restore job, the {\bf bootstrap} file will be created automatically from
+ the files you select to be restored.
+
+ For additional details of the {\bf bootstrap} file, please see
+ \ilink{Restoring Files with the Bootstrap File}{BootstrapChapter} chapter
+ of this manual.
+
+\label{writebootstrap}
+\item [Write Bootstrap = \lt{}bootstrap-file-specification\gt{}]
+\index[dir]{Write Bootstrap}
+\index[dir]{Directive!Write Bootstrap}
+ The {\bf writebootstrap} directive specifies a file name where Bacula
+ will write a {\bf bootstrap} file for each Backup job run. This
+ directive applies only to Backup Jobs. If the Backup job is a Full
+ save, Bacula will erase any current contents of the specified file
+ before writing the bootstrap records. If the Job is an Incremental
+ or Differential
+ save, Bacula will append the current bootstrap record to the end of the
+ file.
+
+ Using this feature, permits you to constantly have a bootstrap file that
+ can recover the current state of your system. Normally, the file
+ specified should be a mounted drive on another machine, so that if your
+ hard disk is lost, you will immediately have a bootstrap record
+ available. Alternatively, you should copy the bootstrap file to another
+ machine after it is updated. Note, it is a good idea to write a separate
+ bootstrap file for each Job backed up including the job that backs up
+ your catalog database.
+
+ If the {\bf bootstrap-file-specification} begins with a vertical bar
+ (|), Bacula will use the specification as the name of a program to which
+ it will pipe the bootstrap record. It could for example be a shell
+ script that emails you the bootstrap record.
+
+ On versions 1.39.22 or greater, before opening the file or executing the
+ specified command, Bacula performs
+ \ilink{character substitution}{character substitution} like in RunScript
+ directive. To automatically manage your bootstrap files, you can use
+ this in your {\bf JobDefs} resources:
+\begin{verbatim}
+JobDefs {
+ Write Bootstrap = "%c_%n.bsr"
+ ...
+}
+\end{verbatim}
+
+ For more details on using this file, please see the chapter entitled
+ \ilink{The Bootstrap File}{BootstrapChapter} of this manual.
+
+\item [Client = \lt{}client-resource-name\gt{}]
+\index[dir]{Client}
+\index[dir]{Directive!Client}
+ The Client directive specifies the Client (File daemon) that will be used in
+ the current Job. Only a single Client may be specified in any one Job. The
+ Client runs on the machine to be backed up, and sends the requested files to
+ the Storage daemon for backup, or receives them when restoring. For
+ additional details, see the
+ \ilink{Client Resource section}{ClientResource2} of this chapter.
+ This directive is required.
+
+\item [FileSet = \lt{}FileSet-resource-name\gt{}]
+\index[dir]{FileSet}
+\index[dir]{FileSet}
+ The FileSet directive specifies the FileSet that will be used in the
+ current Job. The FileSet specifies which directories (or files) are to
+ be backed up, and what options to use (e.g. compression, ...). Only a
+ single FileSet resource may be specified in any one Job. For additional
+ details, see the \ilink{FileSet Resource section}{FileSetResource} of
+ this chapter. This directive is required.
+
+\item [Messages = \lt{}messages-resource-name\gt{}]
+\index[dir]{Messages}
+\index[dir]{Directive!Messages}
+ The Messages directive defines what Messages resource should be used for
+ this job, and thus how and where the various messages are to be
+ delivered. For example, you can direct some messages to a log file, and
+ others can be sent by email. For additional details, see the
+ \ilink{Messages Resource}{MessagesChapter} Chapter of this manual. This
+ directive is required.
+
+\item [Pool = \lt{}pool-resource-name\gt{}]
+\index[dir]{Pool}
+\index[dir]{Directive!Pool}
+ The Pool directive defines the pool of Volumes where your data can be
+ backed up. Many Bacula installations will use only the {\bf Default}
+ pool. However, if you want to specify a different set of Volumes for
+ different Clients or different Jobs, you will probably want to use
+ Pools. For additional details, see the \ilink{Pool Resource
+ section}{PoolResource} of this chapter. This directive is required.
+
+\item [Full Backup Pool = \lt{}pool-resource-name\gt{}]
+\index[dir]{Full Backup Pool}
+\index[dir]{Directive!Full Backup Pool}
+ The {\it Full Backup Pool} specifies a Pool to be used for Full backups.
+ It will override any Pool specification during a Full backup. This
+ directive is optional.
+
+\item [Differential Backup Pool = \lt{}pool-resource-name\gt{}]
+\index[dir]{Differential Backup Pool}
+\index[dir]{Directive!Differential Backup Pool}
+ The {\it Differential Backup Pool} specifies a Pool to be used for
+ Differential backups. It will override any Pool specification during a
+ Differential backup. This directive is optional.
+
+\item [Incremental Backup Pool = \lt{}pool-resource-name\gt{}]
+\index[dir]{Incremental Backup Pool}
+\index[dir]{Directive!Incremental Backup Pool}
+ The {\it Incremental Backup Pool} specifies a Pool to be used for
+ Incremental backups. It will override any Pool specification during an
+ Incremental backup. This directive is optional.
+
+\item [Schedule = \lt{}schedule-name\gt{}]
+\index[dir]{Schedule}
+\index[dir]{Directive!Schedule}
+ The Schedule directive defines what schedule is to be used for the Job.
+ The schedule in turn determines when the Job will be automatically
+ started and what Job level (i.e. Full, Incremental, ...) is to be run.
+ This directive is optional, and if left out, the Job can only be started
+ manually using the Console program. Although you may specify only a
+ single Schedule resource for any one job, the Schedule resource may
+ contain multiple {\bf Run} directives, which allow you to run the Job at
+ many different times, and each {\bf run} directive permits overriding
+ the default Job Level Pool, Storage, and Messages resources. This gives
+ considerable flexibility in what can be done with a single Job. For
+ additional details, see the \ilink{Schedule Resource
+ Chapter}{ScheduleResource} of this manual.
+
+
+\item [Storage = \lt{}storage-resource-name\gt{}]
+\index[dir]{Storage}
+\index[dir]{Directive!Storage}
+ The Storage directive defines the name of the storage services where you
+ want to backup the FileSet data. For additional details, see the
+ \ilink{Storage Resource Chapter}{StorageResource2} of this manual.
+ The Storage resource may also be specified in the Job's Pool resource,
+ in which case the value in the Pool resource overrides any value
+ in the Job. This Storage resource definition is not required by either
+ the Job resource or in the Pool, but it must be specified in
+ one or the other, if not an error will result.
+
+\item [Max Start Delay = \lt{}time\gt{}]
+\index[dir]{Max Start Delay}
+\index[dir]{Directive!Max Start Delay}
+ The time specifies the maximum delay between the scheduled time and the
+ actual start time for the Job. For example, a job can be scheduled to
+ run at 1:00am, but because other jobs are running, it may wait to run.
+ If the delay is set to 3600 (one hour) and the job has not begun to run
+ by 2:00am, the job will be canceled. This can be useful, for example,
+ to prevent jobs from running during day time hours. The default is 0
+ which indicates no limit.
+
+\item [Max Run Time = \lt{}time\gt{}]
+\index[dir]{Max Run Time}
+\index[dir]{Directive!Max Run Time}
+ The time specifies the maximum allowed time that a job may run, counted
+ from when the job starts, ({\bf not} necessarily the same as when the
+ job was scheduled).
+
+\item [Incremental|Differential Max Wait Time = \lt{}time\gt{}]
+\index[dir]{Incremental Wait Run Time}
+\index[dir]{Differential Wait Run Time}
+\index[dir]{Directive!Differential Max Wait Time}
+ Theses directives have been deprecated in favor of
+ \texttt{Incremental|Differential Max Run Time} since bacula 2.3.18.
+
+\item [Incremental Max Run Time = \lt{}time\gt{}]
+\index[dir]{Incremental Max Run Time}
+\index[dir]{Directive!Incremental Max Run Time}
+The time specifies the maximum allowed time that an Incremental backup job may
+run, counted from when the job starts, ({\bf not} necessarily the same as when
+the job was scheduled).
+
+\item [Differential Max Wait Time = \lt{}time\gt{}]
+\index[dir]{Differential Max Run Time}

+\index[dir]{Directive!Max Run Sched Time}
+
+The time specifies the maximum allowed time that a job may run, counted from

+during working hours. We can see it like \texttt{Max Start Delay + Max Run
+ Time}.
+
+\item [Max Wait Time = \lt{}time\gt{}]
+\index[dir]{Max Wait Time}
+\index[dir]{Directive!Max Wait Time}
+ The time specifies the maximum allowed time that a job may block waiting
+ for a resource (such as waiting for a tape to be mounted, or waiting for
+ the storage or file daemons to perform their duties), counted from the
+ when the job starts, ({\bf not} necessarily the same as when the job was

+\item [Max Full Age = \lt{}time\gt{}]
+\index[dir]{Max Full Age}
+\index[dir]{Directive!Max Full Age}
+ The time specifies the maximum allowed age (counting from start time) of

+ Incremental or Differential backup jobs. If the most recent Full backup
+ is older than this interval, Incremental and Differential backups will be
+ upgraded to Full backups automatically. If this directive is not present,

+ considered.
+
+\label{PreferMountedVolumes}
+\item [Prefer Mounted Volumes = \lt{}yes|no\gt{}]
+\index[dir]{Prefer Mounted Volumes}
+\index[dir]{Directive!Prefer Mounted Volumes}
+ If the Prefer Mounted Volumes directive is set to {\bf yes} (default
+ yes), the Storage daemon is requested to select either an Autochanger or
+ a drive with a valid Volume already mounted in preference to a drive
+ that is not ready. This means that all jobs will attempt to append
+ to the same Volume (providing the Volume is appropriate -- right Pool,
+ ... for that job), unless you are using multiple pools.
+ If no drive with a suitable Volume is available, it
+ will select the first available drive. Note, any Volume that has
+ been requested to be mounted, will be considered valid as a mounted
+ volume by another job. This if multiple jobs start at the same time
+ and they all prefer mounted volumes, the first job will request the
+ mount, and the other jobs will use the same volume.
+
+ If the directive is set to {\bf no}, the Storage daemon will prefer
+ finding an unused drive, otherwise, each job started will append to the
+ same Volume (assuming the Pool is the same for all jobs). Setting
+ Prefer Mounted Volumes to no can be useful for those sites
+ with multiple drive autochangers that prefer to maximize backup
+ throughput at the expense of using additional drives and Volumes.
+ This means that the job will prefer to use an unused drive rather
+ than use a drive that is already in use.
+
+ Despite the above, we recommend against setting this directive to
+ {\bf no} since
+ it tends to add a lot of swapping of Volumes between the different
+ drives and can easily lead to deadlock situations in the Storage
+ daemon. We will accept bug reports against it, but we cannot guarantee
+ that we will be able to fix the problem in a reasonable time.
+
+ A better alternative for using multiple drives is to use multiple
+ pools so that Bacula will be forced to mount Volumes from those Pools
+ on different drives.

+\item [Prune Jobs = \lt{}yes|no\gt{}]
+\index[dir]{Prune Jobs}
+\index[dir]{Directive!Prune Jobs}
+ Normally, pruning of Jobs from the Catalog is specified on a Client by

+ If this directive is specified (not normally) and the value is {\bf

+
+
+\item [Prune Files = \lt{}yes|no\gt{}]
+\index[dir]{Prune Files}
+\index[dir]{Directive!Prune Files}
+ Normally, pruning of Files from the Catalog is specified on a Client by

+
+\item [RunScript \{\lt{}body-of-runscript\gt{}\}]
+ \index[dir]{RunScript}
+ \index[dir]{Directive!Run Script}
+
+ This directive is implemented in version 1.39.22 and later.
+ The RunScript directive behaves like a resource in that it
+ requires opening and closing braces around a number of directives
+ that make up the body of the runscript.
+
+ The specified {\bf Command} (see below for details) is run as an
+ external program prior or after the current Job. This is optional.
+
+ \textbf{Console} options are special commands that are sent to the director instead
+ of the OS. At this time, console command ouputs are redirected to log with
+ the jobid 0.
+
+ You can use following console command : \texttt{delete}, \texttt{disable},
+ \texttt{enable}, \texttt{estimate}, \texttt{list}, \texttt{llist},
+ \texttt{memory}, \texttt{prune}, \texttt{purge}, \texttt{reload},
+ \texttt{status}, \texttt{setdebug}, \texttt{show}, \texttt{time},
+ \texttt{trace}, \texttt{update}, \texttt{version}, \texttt{.client},
+ \texttt{.jobs}, \texttt{.pool}, \texttt{.storage}. See console chapter for
+ more information. You need to specify needed information on command line, nothing
+ will be prompted. Example :
+
+\begin{verbatim}
+ Console = "prune files client=%c"
+ Console = "update stats age=3"
+\end{verbatim}
+
+ You can specify more than one Command/Console option per RunScript.
+
+ You can use following options may be specified in the body
+ of the runscript:\\
+
+\begin{tabular}{|c|c|c|l}
+Options & Value & Default & Information \\
+\hline
+\hline
+Runs On Success & Yes/No & {\it Yes} & Run command if JobStatus is successful\\
+\hline
+Runs On Failure & Yes/No & {\it No} & Run command if JobStatus isn't successful\\
+\hline
+Runs On Client & Yes/No & {\it Yes} & Run command on client\\
+\hline
+Runs When & Before|After|Always|\textsl{AfterVSS} & {\it Never} & When run commands\\
+\hline
+Fail Job On Error & Yes/No & {\it Yes} & Fail job if script returns
+ something different from 0 \\
+\hline
+Command & & & Path to your script\\
+\hline
+Console & & & Console command\\
+\hline
+\end{tabular}
+ \\
+
+ Any output sent by the command to standard output will be included in the
+ Bacula job report. The command string must be a valid program name or name
+ of a shell script.
+
+ In addition, the command string is parsed then fed to the OS,
+ which means that the path will be searched to execute your specified
+ command, but there is no shell interpretation, as a consequence, if you
+ invoke complicated commands or want any shell features such as redirection
+ or piping, you must call a shell script and do it inside that script.
+
+ Before submitting the specified command to the operating system, Bacula
+ performs character substitution of the following characters:
+
+\label{character substitution}
+\footnotesize
+\begin{verbatim}
+ %% = %
+ %c = Client's name
+ %d = Director's name
+ %e = Job Exit Status
+ %i = JobId
+ %j = Unique Job id
+ %l = Job Level
+ %n = Job name
+ %s = Since time
+ %t = Job type (Backup, ...)
+ %v = Volume name (Only on director side)
+
+\end{verbatim}
+\normalsize
+
+The Job Exit Status code \%e edits the following values:
+
+\index[dir]{Exit Status}
+\begin{itemize}
+\item OK
+\item Error
+\item Fatal Error
+\item Canceled
+\item Differences
+\item Unknown term code
+\end{itemize}
+
+ Thus if you edit it on a command line, you will need to enclose
+ it within some sort of quotes.
+
+
+You can use these following shortcuts:\\
+
+\begin{tabular}{|c|c|c|c|c|c}
+Keyword & RunsOnSuccess & RunsOnFailure & FailJobOnError & Runs On Client & RunsWhen \\
+\hline
+Run Before Job & & & Yes & No & Before \\
+\hline
+Run After Job & Yes & No & & No & After \\
+\hline
+Run After Failed Job & No & Yes & & No & After \\
+\hline
+Client Run Before Job & & & Yes & Yes & Before \\
+\hline
+Client Run After Job & Yes & No & & Yes & After \\
+\end{tabular}
+
+Examples:
+\begin{verbatim}
+RunScript {
+ RunsWhen = Before
+ FailJobOnError = No
+ Command = "/etc/init.d/apache stop"
+}
+
+RunScript {
+ RunsWhen = After
+ RunsOnFailure = yes
+ Command = "/etc/init.d/apache start"
+}
+\end{verbatim}
+
+ {\bf Notes about ClientRunBeforeJob}
+
+ For compatibility reasons, with this shortcut, the command is executed
+ directly when the client recieve it. And if the command is in error, other
+ remote runscripts will be discarded. To be sure that all commands will be
+ sent and executed, you have to use RunScript syntax.
+
+ {\bf Special Windows Considerations}
+
+ You can run scripts just after snapshots initializations with
+ \textsl{AfterVSS} keyword.
+
+ In addition, for a Windows client on version 1.33 and above, please take
+ note that you must ensure a correct path to your script. The script or
+ program can be a .com, .exe or a .bat file. If you just put the program
+ name in then Bacula will search using the same rules that cmd.exe uses
+ (current directory, Bacula bin directory, and PATH). It will even try the
+ different extensions in the same order as cmd.exe.
+ The command can be anything that cmd.exe or command.com will recognize
+ as an executable file.
+
+ However, if you have slashes in the program name then Bacula figures you
+ are fully specifying the name, so you must also explicitly add the three
+ character extension.
+
+ The command is run in a Win32 environment, so Unix like commands will not
+ work unless you have installed and properly configured Cygwin in addition
+ to and separately from Bacula.
+
+ The System \%Path\% will be searched for the command. (under the
+ environment variable dialog you have have both System Environment and
+ User Environment, we believe that only the System environment will be
+ available to bacula-fd, if it is running as a service.)
+
+ System environment variables can be referenced with \%var\% and
+ used as either part of the command name or arguments.
+
+ So if you have a script in the Bacula\\bin directory then the following lines
+ should work fine:
+
+\footnotesize
+\begin{verbatim}
+ Client Run Before Job = systemstate
+or
+ Client Run Before Job = systemstate.bat
+or
+ Client Run Before Job = "systemstate"
+or
+ Client Run Before Job = "systemstate.bat"
+or
+ ClientRunBeforeJob = "\"C:/Program Files/Bacula/systemstate.bat\""
+\end{verbatim}
+\normalsize
+
+The outer set of quotes is removed when the configuration file is parsed.
+You need to escape the inner quotes so that they are there when the code
+that parses the command line for execution runs so it can tell what the
+program name is.
+
+
+\footnotesize
+\begin{verbatim}
+ClientRunBeforeJob = "\"C:/Program Files/Software
+ Vendor/Executable\" /arg1 /arg2 \"foo bar\""
+\end{verbatim}
+\normalsize
+
+ The special characters
+\begin{verbatim}
+&<>()@^|
+\end{verbatim}
+ will need to be quoted,
+ if they are part of a filename or argument.
+
+ If someone is logged in, a blank "command" window running the commands
+ will be present during the execution of the command.
+
+ Some Suggestions from Phil Stracchino for running on Win32 machines with
+ the native Win32 File daemon:
+
+ \begin{enumerate}
+ \item You might want the ClientRunBeforeJob directive to specify a .bat
+ file which runs the actual client-side commands, rather than trying
+ to run (for example) regedit /e directly.
+ \item The batch file should explicitly 'exit 0' on successful completion.
+ \item The path to the batch file should be specified in Unix form:
+
+ ClientRunBeforeJob = "c:/bacula/bin/systemstate.bat"
+
+ rather than DOS/Windows form:
+
+ ClientRunBeforeJob =
+
+"c:\textbackslash{}bacula\textbackslash{}bin\textbackslash{}systemstate.bat"
+ INCORRECT
+ \end{enumerate}
+
+For Win32, please note that there are certain limitations:
+
+ClientRunBeforeJob = "C:/Program Files/Bacula/bin/pre-exec.bat"
+
+Lines like the above do not work because there are limitations of
+cmd.exe that is used to execute the command.
+Bacula prefixes the string you supply with {\bf cmd.exe /c }. To test that
+your command works you should type {\bf cmd /c "C:/Program Files/test.exe"} at a
+cmd prompt and see what happens. Once the command is correct insert a
+backslash (\textbackslash{}) before each double quote ("), and
+then put quotes around the whole thing when putting it in
+the director's .conf file. You either need to have only one set of quotes
+or else use the short name and don't put quotes around the command path.
+
+Below is the output from cmd's help as it relates to the command line
+passed to the /c option.
+
+
+ If /C or /K is specified, then the remainder of the command line after
+ the switch is processed as a command line, where the following logic is
+ used to process quote (") characters:
+
+\begin{enumerate}
+\item
+ If all of the following conditions are met, then quote characters
+ on the command line are preserved:
+ \begin{itemize}
+ \item no /S switch.
+ \item exactly two quote characters.
+ \item no special characters between the two quote characters,
+ where special is one of:
+\begin{verbatim}
+&<>()@^|
+\end{verbatim}
+ \item there are one or more whitespace characters between the
+ the two quote characters.
+ \item the string between the two quote characters is the name
+ of an executable file.
+ \end{itemize}
+
+\item Otherwise, old behavior is to see if the first character is
+ a quote character and if so, strip the leading character and
+ remove the last quote character on the command line, preserving
+ any text after the last quote character.
+
+\end{enumerate}
+
+
+The following example of the use of the Client Run Before Job directive was
+submitted by a user:\\
+You could write a shell script to back up a DB2 database to a FIFO. The shell
+script is:
+
+\footnotesize
+\begin{verbatim}
+ #!/bin/sh
+ # ===== backupdb.sh
+ DIR=/u01/mercuryd
+
+ mkfifo $DIR/dbpipe
+ db2 BACKUP DATABASE mercuryd TO $DIR/dbpipe WITHOUT PROMPTING &
+ sleep 1
+\end{verbatim}
+\normalsize
+
+The following line in the Job resource in the bacula-dir.conf file:
+\footnotesize
+\begin{verbatim}
+ Client Run Before Job = "su - mercuryd -c \"/u01/mercuryd/backupdb.sh '%t'
+'%l'\""
+\end{verbatim}
+\normalsize
+
+When the job is run, you will get messages from the output of the script
+stating that the backup has started. Even though the command being run is
+backgrounded with \&, the job will block until the "db2 BACKUP DATABASE"
+command, thus the backup stalls.
+
+To remedy this situation, the "db2 BACKUP DATABASE" line should be changed to
+the following:
+
+\footnotesize
+\begin{verbatim}
+ db2 BACKUP DATABASE mercuryd TO $DIR/dbpipe WITHOUT PROMPTING > $DIR/backup.log
+2>&1 < /dev/null &
+\end{verbatim}
+\normalsize
+
+It is important to redirect the input and outputs of a backgrounded command to
+/dev/null to prevent the script from blocking.
+
+\item [Run Before Job = \lt{}command\gt{}]
+\index[dir]{Run Before Job}
+\index[dir]{Directive!Run Before Job}
+\index[dir]{Directive!Run Before Job}
+The specified {\bf command} is run as an external program prior to running the
+current Job. This directive is not required, but if it is defined, and if the
+exit code of the program run is non-zero, the current Bacula job will be
+canceled.
+
+\begin{verbatim}
+Run Before Job = "echo test"
+\end{verbatim}
+ it's equivalent to :
+\begin{verbatim}
+RunScript {
+ Command = "echo test"
+ RunsOnClient = No
+ RunsWhen = Before
+}
+\end{verbatim}
+
+ Lutz Kittler has pointed out that using the RunBeforeJob directive can be a
+ simple way to modify your schedules during a holiday. For example, suppose
+ that you normally do Full backups on Fridays, but Thursday and Friday are
+ holidays. To avoid having to change tapes between Thursday and Friday when
+ no one is in the office, you can create a RunBeforeJob that returns a
+ non-zero status on Thursday and zero on all other days. That way, the
+ Thursday job will not run, and on Friday the tape you inserted on Wednesday
+ before leaving will be used.
+
+\item [Run After Job = \lt{}command\gt{}]
+\index[dir]{Run After Job}
+\index[dir]{Directive!Run After Job}
+ The specified {\bf command} is run as an external program if the current
+ job terminates normally (without error or without being canceled). This
+ directive is not required. If the exit code of the program run is
+ non-zero, Bacula will print a warning message. Before submitting the
+ specified command to the operating system, Bacula performs character
+ substitution as described above for the {\bf RunScript} directive.
+
+ An example of the use of this directive is given in the
+ \ilink{Tips Chapter}{JobNotification} of this manual.
+
+ See the {\bf Run After Failed Job} if you
+ want to run a script after the job has terminated with any
+ non-normal status.
+
+\item [Run After Failed Job = \lt{}command\gt{}]
+\index[dir]{Run After Job}
+\index[dir]{Directive!Run After Job}

+\item [Rerun Failed Levels = \lt{}yes|no\gt{}]
+ \index[dir]{Rerun Failed Levels}
+ \index[dir]{Directive!Rerun Failed Levels}
+ If this directive is set to {\bf yes} (default no), and Bacula detects that
+ a previous job at a higher level (i.e. Full or Differential) has failed,
+ the current job level will be upgraded to the higher level. This is
+ particularly useful for Laptops where they may often be unreachable, and if
+ a prior Full save has failed, you wish the very next backup to be a Full
+ save rather than whatever level it is started as.
+
+ There are several points that must be taken into account when using this
+ directive: first, a failed job is defined as one that has not terminated
+ normally, which includes any running job of the same name (you need to
+ ensure that two jobs of the same name do not run simultaneously);
+ secondly, the {\bf Ignore FileSet Changes} directive is not considered
+ when checking for failed levels, which means that any FileSet change will
+ trigger a rerun.
+
+\item [Spool Data = \lt{}yes|no\gt{}]
+ \index[dir]{Spool Data}
+ \index[dir]{Directive!Spool Data}
+
+ If this directive is set to {\bf yes} (default no), the Storage daemon will
+ be requested to spool the data for this Job to disk rather than write it
+ directly to tape. Once all the data arrives or the spool files' maximum sizes
+ are reached, the data will be despooled and written to tape. Spooling data
+ prevents tape shoe-shine (start and stop) during
+ Incremental saves. If you are writing to a disk file using this option
+ will probably just slow down the backup jobs.
+
+ NOTE: When this directive is set to yes, Spool Attributes is also
+ automatically set to yes.

+ \index[general]{Backups!slow}
+ The default is set to {\bf no}, which means that the File attributes are
+ sent by the Storage daemon to the Director as they are stored on tape.
+ However, if you want to avoid the possibility that database updates will
+ slow down writing to the tape, you may want to set the value to {\bf
+ yes}, in which case the Storage daemon will buffer the File attributes
+ and Storage coordinates to a temporary file in the Working Directory,
+ then when writing the Job data to the tape is completed, the attributes
+ and storage coordinates will be sent to the Director.
+
+ NOTE: When Spool Data is set to yes, Spool Attributes is also

+
+\item [Where = \lt{}directory\gt{}]

+ \index[dir]{Directive!Where}
+ This directive applies only to a Restore job and specifies a prefix to
+ the directory name of all files being restored. This permits files to
+ be restored in a different location from which they were saved. If {\bf
+ Where} is not specified or is set to backslash ({\bf /}), the files will
+ be restored to their original location. By default, we have set {\bf

+\item [Prefix Links=\lt{}yes|no\gt{}]
+ \index[dir]{Prefix Links}
+ \index[dir]{Directive!Prefix Links}
+ If a {\bf Where} path prefix is specified for a recovery job, apply it
+ to absolute links as well. The default is {\bf No}. When set to {\bf
+ Yes} then while restoring files to an alternate directory, any absolute
+ soft links will also be modified to point to the new alternate
+ directory. Normally this is what is desired -- i.e. everything is self
+ consistent. However, if you wish to later move the files to their

+\item [Maximum Concurrent Jobs = \lt{}number\gt{}]
+ \index[dir]{Maximum Concurrent Jobs}
+ \index[dir]{Directive!Maximum Concurrent Jobs}
+ where \lt{}number\gt{} is the maximum number of Jobs from the current

+ \index[dir]{Directive!Reschedule Interval}
+ If you have specified {\bf Reschedule On Error = yes} and the job
+ terminates in error, it will be rescheduled after the interval of time
+ specified by {\bf time-specification}. See \ilink{the time
+ specification formats}{Time} in the Configure chapter for details of
+ time specifications. If no interval is specified, the job will not be
+ rescheduled on error.
+
+\item [Reschedule Times = \lt{}count\gt{}]
+ \index[dir]{Reschedule Times}
+ \index[dir]{Directive!Reschedule Times}
+ This directive specifies the maximum number of times to reschedule the
+ job. If it is set to zero (the default) the job will be rescheduled an
+ indefinite number of times.
+
+\item [Run = \lt{}job-name\gt{}]
+ \index[dir]{Run}
+ \index[dir]{Directive!Run}
+ \index[dir]{Clone a Job}
+ The Run directive (not to be confused with the Run option in a
+ Schedule) allows you to start other jobs or to clone jobs. By using the
+ cloning keywords (see below), you can backup
+ the same data (or almost the same data) to two or more drives
+ at the same time. The {\bf job-name} is normally the same name
+ as the current Job resource (thus creating a clone). However, it
+ may be any Job name, so one job may start other related jobs.
+
+ The part after the equal sign must be enclosed in double quotes,
+ and can contain any string or set of options (overrides) that you
+ can specify when entering the Run command from the console. For
+ example {\bf storage=DDS-4 ...}. In addition, there are two special
+ keywords that permit you to clone the current job. They are {\bf level=\%l}
+ and {\bf since=\%s}. The \%l in the level keyword permits
+ entering the actual level of the current job and the \%s in the since
+ keyword permits putting the same time for comparison as used on the
+ current job. Note, in the case of the since keyword, the \%s must be
+ enclosed in double quotes, and thus they must be preceded by a backslash
+ since they are already inside quotes. For example:
+
+\begin{verbatim}
+ run = "Nightly-backup level=%l since=\"%s\" storage=DDS-4"
+\end{verbatim}
+
+ A cloned job will not start additional clones, so it is not
+ possible to recurse.
+
+ Please note that all cloned jobs, as specified in the Run directives are
+ submitted for running before the original job is run (while it is being
+ initialized). This means that any clone job will actually start before
+ the original job, and may even block the original job from starting
+ until the original job finishes unless you allow multiple simultaneous
+ jobs. Even if you set a lower priority on the clone job, if no other
+ jobs are running, it will start before the original job.
+
+ If you are trying to prioritize jobs by using the clone feature (Run
+ directive), you will find it much easier to do using a RunScript
+ resource, or a RunBeforeJob directive.
+
+\label{Priority}
+\item [Priority = \lt{}number\gt{}]
+ \index[dir]{Priority}
+ \index[dir]{Directive!Priority}
+ This directive permits you to control the order in which your jobs will
+ be run by specifying a positive non-zero number. The higher the number,
+ the lower the job priority. Assuming you are not running concurrent jobs,
+ all queued jobs of priority 1 will run before queued jobs of priority 2
+ and so on, regardless of the original scheduling order.
+
+ The priority only affects waiting jobs that are queued to run, not jobs
+ that are already running. If one or more jobs of priority 2 are already
+ running, and a new job is scheduled with priority 1, the currently
+ running priority 2 jobs must complete before the priority 1 job is
+ run, unless Allow Mixed Priority is set.
+
+ The default priority is 10.
+
+ If you want to run concurrent jobs you should
+ keep these points in mind:
+
+\begin{itemize}
+\item See \ilink{Running Concurrent Jobs}{ConcurrentJobs} on how to setup
+ concurrent jobs.
+
+\item Bacula concurrently runs jobs of only one priority at a time. It
+ will not simultaneously run a priority 1 and a priority 2 job.
+
+\item If Bacula is running a priority 2 job and a new priority 1 job is
+ scheduled, it will wait until the running priority 2 job terminates even
+ if the Maximum Concurrent Jobs settings would otherwise allow two jobs
+ to run simultaneously.
+
+\item Suppose that bacula is running a priority 2 job and a new priority 1
+ job is scheduled and queued waiting for the running priority 2 job to
+ terminate. If you then start a second priority 2 job, the waiting
+ priority 1 job will prevent the new priority 2 job from running
+ concurrently with the running priority 2 job. That is: as long as there
+ is a higher priority job waiting to run, no new lower priority jobs will
+ start even if the Maximum Concurrent Jobs settings would normally allow
+ them to run. This ensures that higher priority jobs will be run as soon
+ as possible.
+\end{itemize}
+
+If you have several jobs of different priority, it may not best to start
+them at exactly the same time, because Bacula must examine them one at a
+time. If by Bacula starts a lower priority job first, then it will run
+before your high priority jobs. If you experience this problem, you may
+avoid it by starting any higher priority jobs a few seconds before lower
+priority ones. This insures that Bacula will examine the jobs in the
+correct order, and that your priority scheme will be respected.
+
+\label{AllowMixedPriority}
+\item [Allow Mixed Priority = \lt{}yes|no\gt{}]
+\index[dir]{Allow Mixed Priority}
+ This directive is only implemented in version 2.5 and later. When
+ set to {\bf yes} (default {\bf no}), this job may run even if lower
+ priority jobs are already running. This means a high priority job
+ will not have to wait for other jobs to finish before starting.
+ The scheduler will only mix priorities when all running jobs have
+ this set to true.
+
+ Note that only higher priority jobs will start early. Suppose the
+ director will allow two concurrent jobs, and that two jobs with
+ priority 10 are running, with two more in the queue. If a job with
+ priority 5 is added to the queue, it will be run as soon as one of
+ the running jobs finishes. However, new priority 10 jobs will not
+ be run until the priority 5 job has finished.
+
+\label{WritePartAfterJob}
+\item [Write Part After Job = \lt{}yes|no\gt{}]
+\index[dir]{Write Part After Job}
+\index[dir]{Directive!Write Part After Job}
+ This directive is only implemented in version 1.37 and later.
+ If this directive is set to {\bf yes} (default {\bf no}), a new part file
+ will be created after the job is finished.
+
+ It should be set to {\bf yes} when writing to devices that require mount
+ (for example DVD), so you are sure that the current part, containing
+ this job's data, is written to the device, and that no data is left in
+ the temporary file on the hard disk. However, on some media, like DVD+R
+ and DVD-R, a lot of space (about 10Mb) is lost every time a part is
+ written. So, if you run several jobs each after another, you could set
+ this directive to {\bf no} for all jobs, except the last one, to avoid
+ wasting too much space, but to ensure that the data is written to the
+ medium when all jobs are finished.
+
+ This directive is ignored with tape and FIFO devices.
+

+The following is an example of a valid Job resource definition:
+
+\footnotesize
+\begin{verbatim}
+Job {
+ Name = "Minou"
+ Type = Backup
+ Level = Incremental # default
+ Client = Minou
+ FileSet="Minou Full Set"
+ Storage = DLTDrive
+ Pool = Default
+ Schedule = "MinouWeeklyCycle"
+ Messages = Standard
+}
+\end{verbatim}
+\normalsize
+
+\section{The JobDefs Resource}
+\label{JobDefsResource}
+\index[general]{JobDefs Resource}
+\index[general]{Resource!JobDefs}
+
+The JobDefs resource permits all the same directives that can appear in a Job
+resource. However, a JobDefs resource does not create a Job, rather it can be
+referenced within a Job to provide defaults for that Job. This permits you to
+concisely define several nearly identical Jobs, each one referencing a JobDefs
+resource which contains the defaults. Only the changes from the defaults need to
+be mentioned in each Job.
+
+\section{The Schedule Resource}
+\label{ScheduleResource}
+\index[general]{Resource!Schedule}
+\index[general]{Schedule Resource}
+
+The Schedule resource provides a means of automatically scheduling a Job as
+well as the ability to override the default Level, Pool, Storage and Messages
+resources. If a Schedule resource is not referenced in a Job, the Job can only
+be run manually. In general, you specify an action to be taken and when.
+
+\begin{description}
+
+\item [Schedule]
+\index[dir]{Schedule}
+\index[dir]{Directive!Schedule}
+ Start of the Schedule directives. No {\bf Schedule} resource is
+ required, but you will need at least one if you want Jobs to be
+ automatically started.
+
+\item [Name = \lt{}name\gt{}]
+ \index[dir]{Name}
+ \index[dir]{Directive!Name}
+ The name of the schedule being defined. The Name directive is required.
+
+\item [Run = \lt{}Job-overrides\gt{} \lt{}Date-time-specification\gt{}]
+ \index[dir]{Run}
+ \index[dir]{Directive!Run}
+ The Run directive defines when a Job is to be run, and what overrides if
+ any to apply. You may specify multiple {\bf run} directives within a
+ {\bf Schedule} resource. If you do, they will all be applied (i.e.
+ multiple schedules). If you have two {\bf Run} directives that start at
+ the same time, two Jobs will start at the same time (well, within one
+ second of each other).
+
+ The {\bf Job-overrides} permit overriding the Level, the Storage, the
+ Messages, and the Pool specifications provided in the Job resource. In
+ addition, the FullPool, the IncrementalPool, and the DifferentialPool
+ specifications permit overriding the Pool specification according to
+ what backup Job Level is in effect.
+
+ By the use of overrides, you may customize a particular Job. For
+ example, you may specify a Messages override for your Incremental
+ backups that outputs messages to a log file, but for your weekly or
+ monthly Full backups, you may send the output by email by using a
+ different Messages override.
+
+ {\bf Job-overrides} are specified as: {\bf keyword=value} where the
+ keyword is Level, Storage, Messages, Pool, FullPool, DifferentialPool,
+ or IncrementalPool, and the {\bf value} is as defined on the respective
+ directive formats for the Job resource. You may specify multiple {\bf
+ Job-overrides} on one {\bf Run} directive by separating them with one or
+ more spaces or by separating them with a trailing comma. For example:
+
+\begin{description}
+
+\item [Level=Full]
+ \index[dir]{Level}
+ \index[dir]{Directive!Level}
+ is all files in the FileSet whether or not they have changed.
+
+\item [Level=Incremental]
+ \index[dir]{Level}
+ \index[dir]{Directive!Level}
+ is all files that have changed since the last backup.
+
+\item [Pool=Weekly]
+ \index[dir]{Pool}
+ \index[dir]{Directive!Pool}
+ specifies to use the Pool named {\bf Weekly}.
+
+\item [Storage=DLT\_Drive]
+ \index[dir]{Storage}
+ \index[dir]{Directive!Storage}
+ specifies to use {\bf DLT\_Drive} for the storage device.
+
+\item [Messages=Verbose]
+ \index[dir]{Messages}
+ \index[dir]{Directive!Messages}
+ specifies to use the {\bf Verbose} message resource for the Job.
+
+\item [FullPool=Full]
+ \index[dir]{FullPool}
+ \index[dir]{Directive!FullPool}
+ specifies to use the Pool named {\bf Full} if the job is a full backup, or
+is
+upgraded from another type to a full backup.
+
+\item [DifferentialPool=Differential]
+ \index[dir]{DifferentialPool}
+ \index[dir]{Directive!DifferentialPool}
+ specifies to use the Pool named {\bf Differential} if the job is a
+ differential backup.
+
+\item [IncrementalPool=Incremental]
+ \index[dir]{IncrementalPool}
+ \index[dir]{Directive!IncrementalPool}
+ specifies to use the Pool named {\bf Incremental} if the job is an
+incremental backup.
+
+\item [SpoolData=yes|no]
+ \index[dir]{SpoolData}
+ \index[dir]{Directive!SpoolData}
+ tells Bacula to request the Storage daemon to spool data to a disk file
+ before writing it to the Volume (normally a tape). Thus the data is
+ written in large blocks to the Volume rather than small blocks. This
+ directive is particularly useful when running multiple simultaneous
+ backups to tape. It prevents interleaving of the job data and reduces
+ or eliminates tape drive stop and start commonly known as "shoe-shine".
+
+\item [SpoolSize={\it bytes}]
+ \index[dir]{SpoolSize}
+ \index[dir]{Directive!SpoolSize}
+ where the bytes specify the maximum spool size for this job.
+ The default is take from Device Maximum Spool Size limit.
+ This directive is available only in Bacula version 2.3.5 or
+ later.
+
+\item [WritePartAfterJob=yes|no]
+ \index[dir]{WritePartAfterJob}
+ \index[dir]{Directive!WritePartAfterJob}
+ tells Bacula to request the Storage daemon to write the current part
+ file to the device when the job is finished (see \ilink{Write Part After
+ Job directive in the Job resource}{WritePartAfterJob}). Please note,
+ this directive is implemented only in version 1.37 and later. The
+ default is yes. We strongly recommend that you keep this set to yes
+ otherwise, when the last job has finished one part will remain in the
+ spool file and restore may or may not work.
+
+\end{description}
+
+{\bf Date-time-specification} determines when the Job is to be run. The
+specification is a repetition, and as a default Bacula is set to run a job at
+the beginning of the hour of every hour of every day of every week of every
+month of every year. This is not normally what you want, so you must specify
+or limit when you want the job to run. Any specification given is assumed to
+be repetitive in nature and will serve to override or limit the default
+repetition. This is done by specifying masks or times for the hour, day of the
+month, day of the week, week of the month, week of the year, and month when
+you want the job to run. By specifying one or more of the above, you can
+define a schedule to repeat at almost any frequency you want.
+
+Basically, you must supply a {\bf month}, {\bf day}, {\bf hour}, and {\bf
+minute} the Job is to be run. Of these four items to be specified, {\bf day}
+is special in that you may either specify a day of the month such as 1, 2,
+... 31, or you may specify a day of the week such as Monday, Tuesday, ...
+Sunday. Finally, you may also specify a week qualifier to restrict the
+schedule to the first, second, third, fourth, or fifth week of the month.
+
+For example, if you specify only a day of the week, such as {\bf Tuesday} the
+Job will be run every hour of every Tuesday of every Month. That is the {\bf
+month} and {\bf hour} remain set to the defaults of every month and all
+hours.
+
+Note, by default with no other specification, your job will run at the
+beginning of every hour. If you wish your job to run more than once in any
+given hour, you will need to specify multiple {\bf run} specifications each
+with a different minute.
+
+The date/time to run the Job can be specified in the following way in
+pseudo-BNF:
+
+\footnotesize
+\begin{verbatim}
+<void-keyword> = on
+<at-keyword> = at
+<week-keyword> = 1st | 2nd | 3rd | 4th | 5th | first |

+<date-time-spec> = <month-spec> <day-spec> <time-spec>
+\end{verbatim}

+
+\end{description}
+
+Note, the Week of Year specification wnn follows the ISO standard definition
+of the week of the year, where Week 1 is the week in which the first Thursday
+of the year occurs, or alternatively, the week which contains the 4th of
+January. Weeks are numbered w01 to w53. w00 for Bacula is the week that
+precedes the first ISO week (i.e. has the first few days of the year if any
+occur before Thursday). w00 is not defined by the ISO specification. A week
+starts with Monday and ends with Sunday.
+
+According to the NIST (US National Institute of Standards and Technology),
+12am and 12pm are ambiguous and can be defined to anything. However,
+12:01am is the same as 00:01 and 12:01pm is the same as 12:01, so Bacula
+defines 12am as 00:00 (midnight) and 12pm as 12:00 (noon). You can avoid
+this abiguity (confusion) by using 24 hour time specifications (i.e. no
+am/pm). This is the definition in Bacula version 2.0.3 and later.
+
+An example schedule resource that is named {\bf WeeklyCycle} and runs a job
+with level full each Sunday at 2:05am and an incremental job Monday through
+Saturday at 2:05am is:
+
+\footnotesize
+\begin{verbatim}
+Schedule {
+ Name = "WeeklyCycle"
+ Run = Level=Full sun at 2:05
+ Run = Level=Incremental mon-sat at 2:05
+}
+\end{verbatim}
+\normalsize
+
+An example of a possible monthly cycle is as follows:
+
+\footnotesize
+\begin{verbatim}
+Schedule {
+ Name = "MonthlyCycle"
+ Run = Level=Full Pool=Monthly 1st sun at 2:05
+ Run = Level=Differential 2nd-5th sun at 2:05
+ Run = Level=Incremental Pool=Daily mon-sat at 2:05
+}
+\end{verbatim}
+\normalsize
+
+The first of every month:
+
+\footnotesize
+\begin{verbatim}
+Schedule {
+ Name = "First"
+ Run = Level=Full on 1 at 2:05
+ Run = Level=Incremental on 2-31 at 2:05
+}
+\end{verbatim}
+\normalsize
+
+Every 10 minutes:
+
+\footnotesize
+\begin{verbatim}

+\section{Technical Notes on Schedules}
+\index[general]{Schedules!Technical Notes on}
+\index[general]{Technical Notes on Schedules}
+
+Internally Bacula keeps a schedule as a bit mask. There are six masks and a
+minute field to each schedule. The masks are hour, day of the month (mday),
+month, day of the week (wday), week of the month (wom), and week of the year
+(woy). The schedule is initialized to have the bits of each of these masks
+set, which means that at the beginning of every hour, the job will run. When
+you specify a month for the first time, the mask will be cleared and the bit
+corresponding to your selected month will be selected. If you specify a second
+month, the bit corresponding to it will also be added to the mask. Thus when
+Bacula checks the masks to see if the bits are set corresponding to the
+current time, your job will run only in the two months you have set. Likewise,
+if you set a time (hour), the hour mask will be cleared, and the hour you
+specify will be set in the bit mask and the minutes will be stored in the
+minute field.
+
+For any schedule you have defined, you can see how these bits are set by doing
+a {\bf show schedules} command in the Console program. Please note that the
+bit mask is zero based, and Sunday is the first day of the week (bit zero).

+\section{The Client Resource}
+\label{ClientResource2}
+\index[general]{Resource!Client}
+\index[general]{Client Resource}
+
+The Client resource defines the attributes of the Clients that are served by
+this Director; that is the machines that are to be backed up. You will need
+one Client resource definition for each machine to be backed up.
+
+\begin{description}
+
+\item [Client (or FileDaemon)]
+ \index[dir]{Client (or FileDaemon)}
+ \index[dir]{Directive!Client (or FileDaemon)}
+ Start of the Client directives.
+
+\item [Name = \lt{}name\gt{}]
+ \index[dir]{Name}
+ \index[dir]{Directive!Name}
+ The client name which will be used in the Job resource directive or in the
+console run command. This directive is required.
+
+\item [Address = \lt{}address\gt{}]
+ \index[dir]{Address}
+ \index[dir]{Directive!FD Address}
+ \index[dir]{File Daemon Address}
+ \index[dir]{Client Address}
+ Where the address is a host name, a fully qualified domain name, or a
+ network address in dotted quad notation for a Bacula File server daemon.
+ This directive is required.
+
+\item [FD Port = \lt{}port-number\gt{}]
+ \index[dir]{FD Port}
+ \index[dir]{Directive!FD Port}
+ Where the port is a port number at which the Bacula File server daemon can
+ be contacted. The default is 9102.
+
+\item [Catalog = \lt{}Catalog-resource-name\gt{}]
+ \index[dir]{Catalog}
+ \index[dir]{Directive!Catalog}
+ This specifies the name of the catalog resource to be used for this Client.
+ This directive is required.
+
+\item [Password = \lt{}password\gt{}]
+ \index[dir]{Password}
+ \index[dir]{Directive!Password}
+ This is the password to be used when establishing a connection with the File
+ services, so the Client configuration file on the machine to be backed up
+ must have the same password defined for this Director. This directive is
+ required. If you have either {\bf /dev/random} {\bf bc} on your machine,
+ Bacula will generate a random password during the configuration process,
+ otherwise it will be left blank.
+
+ The password is plain text. It is not generated through any special
+ process, but it is preferable for security reasons to make the text
+ random.
+
+\label{FileRetention}
+\item [File Retention = \lt{}time-period-specification\gt{}]
+ \index[dir]{File Retention}
+ \index[dir]{Directive!File Retention}
+ The File Retention directive defines the length of time that Bacula will
+ keep File records in the Catalog database after the End time of the
+ Job corresponding to the File records.
+ When this time period expires, and if
+ {\bf AutoPrune} is set to {\bf yes} Bacula will prune (remove) File records
+ that are older than the specified File Retention period. Note, this affects
+ only records in the catalog database. It does not affect your archive
+ backups.
+
+ File records may actually be retained for a shorter period than you specify
+ on this directive if you specify either a shorter {\bf Job Retention} or a
+ shorter {\bf Volume Retention} period. The shortest retention period of the
+ three takes precedence. The time may be expressed in seconds, minutes,
+ hours, days, weeks, months, quarters, or years. See the
+ \ilink{ Configuration chapter}{Time} of this manual for
+ additional details of time specification.
+
+ The default is 60 days.
+
+\label{JobRetention}
+\item [Job Retention = \lt{}time-period-specification\gt{}]
+ \index[dir]{Job Retention}
+ \index[dir]{Directive!Job Retention}
+ The Job Retention directive defines the length of time that Bacula will keep
+ Job records in the Catalog database after the Job End time. When
+ this time period expires, and if {\bf AutoPrune} is set to {\bf yes}
+ Bacula will prune (remove) Job records that are older than the specified
+ File Retention period. As with the other retention periods, this
+ affects only records in the catalog and not data in your archive backup.
+
+ If a Job record is selected for pruning, all associated File and JobMedia
+ records will also be pruned regardless of the File Retention period set.
+ As a consequence, you normally will set the File retention period to be
+ less than the Job retention period. The Job retention period can actually
+ be less than the value you specify here if you set the {\bf Volume
+ Retention} directive in the Pool resource to a smaller duration. This is
+ because the Job retention period and the Volume retention period are
+ independently applied, so the smaller of the two takes precedence.
+
+ The Job retention period is specified as seconds, minutes, hours, days,
+ weeks, months, quarters, or years. See the
+ \ilink{ Configuration chapter}{Time} of this manual for
+ additional details of time specification.
+
+ The default is 180 days.
+
+\label{AutoPrune}
+\item [AutoPrune = \lt{}yes|no\gt{}]
+ \index[dir]{AutoPrune}
+ \index[dir]{Directive!AutoPrune}
+ If AutoPrune is set to {\bf yes} (default), Bacula (version 1.20 or greater)
+ will automatically apply the File retention period and the Job retention
+ period for the Client at the end of the Job. If you set {\bf AutoPrune = no},
+ pruning will not be done, and your Catalog will grow in size each time you
+ run a Job. Pruning affects only information in the catalog and not data
+ stored in the backup archives (on Volumes).
+
+\item [Maximum Concurrent Jobs = \lt{}number\gt{}]
+ \index[dir]{Maximum Concurrent Jobs}
+ \index[dir]{Directive!Maximum Concurrent Jobs}
+ where \lt{}number\gt{} is the maximum number of Jobs with the current Client
+ that can run concurrently. Note, this directive limits only Jobs for Clients
+ with the same name as the resource in which it appears. Any other
+ restrictions on the maximum concurrent jobs such as in the Director, Job, or
+ Storage resources will also apply in addition to any limit specified here.
+ The default is set to 1, but you may set it to a larger number.
+
+\item [Priority = \lt{}number\gt{}]
+ \index[dir]{Priority}
+ \index[dir]{Directive!Priority}
+ The number specifies the priority of this client relative to other clients
+ that the Director is processing simultaneously. The priority can range from
+ 1 to 1000. The clients are ordered such that the smaller number priorities
+ are performed first (not currently implemented).
+\end{description}
+
+ The following is an example of a valid Client resource definition:

+\begin{verbatim}
+Client {
+ Name = Minimatou

+ Password = very_good
+}
+\end{verbatim}

+The Storage resource defines which Storage daemons are available for use by
+the Director.
+
+\begin{description}
+
+\item [Storage]
+ \index[dir]{Storage}
+ \index[dir]{Directive!Storage}
+ Start of the Storage resources. At least one storage resource must be
+ specified.
+
+\item [Name = \lt{}name\gt{}]
+ \index[dir]{Name}
+ \index[dir]{Directive!Name}
+ The name of the storage resource. This name appears on the Storage directive
+ specified in the Job resource and is required.
+
+\item [Address = \lt{}address\gt{}]
+ \index[dir]{Address}
+ \index[dir]{Directive!SD Address}
+ \index[dir]{Storage daemon Address}
+ Where the address is a host name, a {\bf fully qualified domain name}, or an
+ {\bf IP address}. Please note that the \lt{}address\gt{} as specified here
+ will be transmitted to the File daemon who will then use it to contact the
+ Storage daemon. Hence, it is {\bf not}, a good idea to use {\bf localhost} as
+ the name but rather a fully qualified machine name or an IP address. This
+ directive is required.
+
+\item [SD Port = \lt{}port\gt{}]
+ \index[dir]{SD Port}
+ \index[dir]{Directive!SD Port}
+ Where port is the port to use to contact the storage daemon for information
+ and to start jobs. This same port number must appear in the Storage resource
+ of the Storage daemon's configuration file. The default is 9103.
+
+\item [Password = \lt{}password\gt{}]
+ \index[dir]{Password}
+ \index[dir]{Directive!Password}
+ This is the password to be used when establishing a connection with the
+ Storage services. This same password also must appear in the Director
+ resource of the Storage daemon's configuration file. This directive is
+ required. If you have either {\bf /dev/random} {\bf bc} on your machine,
+ Bacula will generate a random password during the configuration process,
+ otherwise it will be left blank.
+
+ The password is plain text. It is not generated through any special
+ process, but it is preferable for security reasons to use random text.
+
+\item [Device = \lt{}device-name\gt{}]
+ \index[dir]{Device}
+ \index[dir]{Directive!Device}
+ This directive specifies the Storage daemon's name of the device
+ resource to be used for the storage. If you are using an Autochanger,
+ the name specified here should be the name of the Storage daemon's
+ Autochanger resource rather than the name of an individual device. This
+ name is not the physical device name, but the logical device name as
+ defined on the {\bf Name} directive contained in the {\bf Device} or the
+ {\bf Autochanger} resource definition of the {\bf Storage daemon}
+ configuration file. You can specify any name you would like (even the
+ device name if you prefer) up to a maximum of 127 characters in length.
+ The physical device name associated with this device is specified in the
+ {\bf Storage daemon} configuration file (as {\bf Archive Device}).
+ Please take care not to define two different Storage resource directives
+ in the Director that point to the same Device in the Storage daemon.
+ Doing so may cause the Storage daemon to block (or hang) attempting to
+ open the same device that is already open. This directive is required.
+
+\label{MediaType}
+\item [Media Type = \lt{}MediaType\gt{}]
+ \index[dir]{Media Type}
+ \index[dir]{Directive!Media Type}
+ This directive specifies the Media Type to be used to store the data.
+ This is an arbitrary string of characters up to 127 maximum that you
+ define. It can be anything you want. However, it is best to make it
+ descriptive of the storage media (e.g. File, DAT, "HP DLT8000", 8mm,
+ ...). In addition, it is essential that you make the {\bf Media Type}
+ specification unique for each storage media type. If you have two DDS-4
+ drives that have incompatible formats, or if you have a DDS-4 drive and
+ a DDS-4 autochanger, you almost certainly should specify different {\bf
+ Media Types}. During a restore, assuming a {\bf DDS-4} Media Type is
+ associated with the Job, Bacula can decide to use any Storage daemon
+ that supports Media Type {\bf DDS-4} and on any drive that supports it.
+
+ If you are writing to disk Volumes, you must make doubly sure that each
+ Device resource defined in the Storage daemon (and hence in the
+ Director's conf file) has a unique media type. Otherwise for Bacula
+ versions 1.38 and older, your restores may not work because Bacula
+ will assume that you can mount any Media Type with the same name on
+ any Device associated with that Media Type. This is possible with
+ tape drives, but with disk drives, unless you are very clever you
+ cannot mount a Volume in any directory -- this can be done by creating
+ an appropriate soft link.
+
+ Currently Bacula permits only a single Media Type per Storage
+ and Device definition. Consequently, if
+ you have a drive that supports more than one Media Type, you can
+ give a unique string to Volumes with different intrinsic Media
+ Type (Media Type = DDS-3-4 for DDS-3 and DDS-4 types), but then
+ those volumes will only be mounted on drives indicated with the
+ dual type (DDS-3-4).
+
+ If you want to tie Bacula to using a single Storage daemon or drive, you
+ must specify a unique Media Type for that drive. This is an important
+ point that should be carefully understood. Note, this applies equally
+ to Disk Volumes. If you define more than one disk Device resource in
+ your Storage daemon's conf file, the Volumes on those two devices are in
+ fact incompatible because one can not be mounted on the other device
+ since they are found in different directories. For this reason, you
+ probably should use two different Media Types for your two disk Devices
+ (even though you might think of them as both being File types). You can
+ find more on this subject in the \ilink{Basic Volume
+ Management}{DiskChapter} chapter of this manual.
+
+ The {\bf MediaType} specified in the Director's Storage resource, {\bf
+ must} correspond to the {\bf Media Type} specified in the {\bf Device}
+ resource of the {\bf Storage daemon} configuration file. This directive
+ is required, and it is used by the Director and the Storage daemon to
+ ensure that a Volume automatically selected from the Pool corresponds to
+ the physical device. If a Storage daemon handles multiple devices (e.g.
+ will write to various file Volumes on different partitions), this
+ directive allows you to specify exactly which device.
+
+ As mentioned above, the value specified in the Director's Storage
+ resource must agree with the value specified in the Device resource in
+ the {\bf Storage daemon's} configuration file. It is also an additional
+ check so that you don't try to write data for a DLT onto an 8mm device.
+
+\label{Autochanger1}
+\item [Autochanger = \lt{}yes|no\gt{}]
+ \index[dir]{Autochanger}
+ \index[dir]{Directive!Autochanger}
+ If you specify {\bf yes} for this command (the default is {\bf no}),
+ when you use the {\bf label} command or the {\bf add} command to create
+ a new Volume, {\bf Bacula} will also request the Autochanger Slot
+ number. This simplifies creating database entries for Volumes in an
+ autochanger. If you forget to specify the Slot, the autochanger will
+ not be used. However, you may modify the Slot associated with a Volume
+ at any time by using the {\bf update volume} or {\bf update slots}
+ command in the console program. When {\bf autochanger} is enabled, the
+ algorithm used by Bacula to search for available volumes will be
+ modified to consider only Volumes that are known to be in the
+ autochanger's magazine. If no {\bf in changer} volume is found, Bacula
+ will attempt recycling, pruning, ..., and if still no volume is found,
+ Bacula will search for any volume whether or not in the magazine. By
+ privileging in changer volumes, this procedure minimizes operator
+ intervention. The default is {\bf no}.
+
+ For the autochanger to be used, you must also specify {\bf Autochanger =
+ yes} in the \ilink{Device Resource}{Autochanger} in the Storage daemon's
+ configuration file as well as other important Storage daemon
+ configuration information. Please consult the \ilink{Using
+ Autochangers}{AutochangersChapter} manual of this chapter for the
+ details of using autochangers.
+
+\item [Maximum Concurrent Jobs = \lt{}number\gt{}]
+ \index[dir]{Maximum Concurrent Jobs}
+ \index[dir]{Directive!Maximum Concurrent Jobs}
+ where \lt{}number\gt{} is the maximum number of Jobs with the current
+ Storage resource that can run concurrently. Note, this directive limits
+ only Jobs for Jobs using this Storage daemon. Any other restrictions on
+ the maximum concurrent jobs such as in the Director, Job, or Client
+ resources will also apply in addition to any limit specified here. The
+ default is set to 1, but you may set it to a larger number. However, if
+ you set the Storage daemon's number of concurrent jobs greater than one,
+ we recommend that you read the waring documented under \ilink{Maximum
+ Concurrent Jobs}{DirMaxConJobs} in the Director's resource or simply
+ turn data spooling on as documented in the \ilink{Data
+ Spooling}{SpoolingChapter} chapter of this manual.
+
+\item [Heartbeat Interval = \lt{}time-interval\gt{}]
+ \index[dir]{Heartbeat Interval}
+ \index[dir]{Directive!Heartbeat}
+ This directive is optional and if specified will cause the Director to
+ set a keepalive interval (heartbeat) in seconds on each of the sockets
+ it opens for the Storage resource. This value will override any
+ specified at the Director level. It is implemented only on systems
+ (Linux, ...) that provide the {\bf setsockopt} TCP\_KEEPIDLE function.
+ The default value is zero, which means no change is made to the socket.
+

+\section{The Pool Resource}
+\label{PoolResource}
+\index[general]{Resource!Pool}
+\index[general]{Pool Resource}
+
+The Pool resource defines the set of storage Volumes (tapes or files) to be
+used by Bacula to write the data. By configuring different Pools, you can
+determine which set of Volumes (media) receives the backup data. This permits,
+for example, to store all full backup data on one set of Volumes and all
+incremental backups on another set of Volumes. Alternatively, you could assign
+a different set of Volumes to each machine that you backup. This is most
+easily done by defining multiple Pools.
+
+Another important aspect of a Pool is that it contains the default attributes
+(Maximum Jobs, Retention Period, Recycle flag, ...) that will be given to a
+Volume when it is created. This avoids the need for you to answer a large
+number of questions when labeling a new Volume. Each of these attributes can
+later be changed on a Volume by Volume basis using the {\bf update} command in
+the console program. Note that you must explicitly specify which Pool Bacula
+is to use with each Job. Bacula will not automatically search for the correct
+Pool.
+
+Most often in Bacula installations all backups for all machines (Clients) go
+to a single set of Volumes. In this case, you will probably only use the {\bf
+Default} Pool. If your backup strategy calls for you to mount a different tape
+each day, you will probably want to define a separate Pool for each day. For
+more information on this subject, please see the
+\ilink{Backup Strategies}{StrategiesChapter} chapter of this
+manual.
+
+
+To use a Pool, there are three distinct steps. First the Pool must be defined
+in the Director's configuration file. Then the Pool must be written to the
+Catalog database. This is done automatically by the Director each time that it
+starts, or alternatively can be done using the {\bf create} command in the
+console program. Finally, if you change the Pool definition in the Director's
+configuration file and restart Bacula, the pool will be updated alternatively
+you can use the {\bf update pool} console command to refresh the database
+image. It is this database image rather than the Director's resource image
+that is used for the default Volume attributes. Note, for the pool to be
+automatically created or updated, it must be explicitly referenced by a Job
+resource.
+
+Next the physical media must be labeled. The labeling can either be done with
+the {\bf label} command in the {\bf console} program or using the {\bf btape}
+program. The preferred method is to use the {\bf label} command in the {\bf
+console} program.
+
+Finally, you must add Volume names (and their attributes) to the Pool. For
+Volumes to be used by Bacula they must be of the same {\bf Media Type} as the
+archive device specified for the job (i.e. if you are going to back up to a
+DLT device, the Pool must have DLT volumes defined since 8mm volumes cannot be
+mounted on a DLT drive). The {\bf Media Type} has particular importance if you
+are backing up to files. When running a Job, you must explicitly specify which
+Pool to use. Bacula will then automatically select the next Volume to use from
+the Pool, but it will ensure that the {\bf Media Type} of any Volume selected
+from the Pool is identical to that required by the Storage resource you have
+specified for the Job.
+
+If you use the {\bf label} command in the console program to label the
+Volumes, they will automatically be added to the Pool, so this last step is
+not normally required.
+
+It is also possible to add Volumes to the database without explicitly labeling
+the physical volume. This is done with the {\bf add} console command.
+
+As previously mentioned, each time Bacula starts, it scans all the Pools
+associated with each Catalog, and if the database record does not already
+exist, it will be created from the Pool Resource definition. {\bf Bacula}
+probably should do an {\bf update pool} if you change the Pool definition, but
+currently, you must do this manually using the {\bf update pool} command in
+the Console program.
+
+The Pool Resource defined in the Director's configuration file
+(bacula-dir.conf) may contain the following directives:
+
+\begin{description}
+
+\item [Pool]
+ \index[dir]{Pool}
+ \index[dir]{Directive!Pool}
+ Start of the Pool resource. There must be at least one Pool resource
+ defined.
+
+
+\item [Name = \lt{}name\gt{}]
+ \index[dir]{Name}
+ \index[dir]{Directive!Name}
+ The name of the pool. For most applications, you will use the default
+ pool name {\bf Default}. This directive is required.
+
+\label{MaxVolumes}
+\item [Maximum Volumes = \lt{}number\gt{}]
+ \index[dir]{Maximum Volumes}
+ \index[dir]{Directive!Maximum Volumes}
+ This directive specifies the maximum number of volumes (tapes or files)
+ contained in the pool. This directive is optional, if omitted or set to
+ zero, any number of volumes will be permitted. In general, this
+ directive is useful for Autochangers where there is a fixed number of
+ Volumes, or for File storage where you wish to ensure that the backups
+ made to disk files do not become too numerous or consume too much space.
+
+\item [Pool Type = \lt{}type\gt{}]
+ \index[dir]{Pool Type}
+ \index[dir]{Directive!Pool Type}
+ This directive defines the pool type, which corresponds to the type of
+ Job being run. It is required and may be one of the following:
+
+\begin{itemize}
+ \item [Backup]
+ \item [*Archive]
+ \item [*Cloned]
+ \item [*Migration]
+ \item [*Copy]
+ \item [*Save]
+\end{itemize}
+ Note, only Backup is current implemented.
+
+\item [Storage = \lt{}storage-resource-name\gt{}]
+\index[dir]{Storage}
+\index[dir]{Directive!Storage}
+ The Storage directive defines the name of the storage services where you
+ want to backup the FileSet data. For additional details, see the
+ \ilink{Storage Resource Chapter}{StorageResource2} of this manual.
+ The Storage resource may also be specified in the Job resource,
+ but the value, if any, in the Pool resource overrides any value
+ in the Job. This Storage resource definition is not required by either
+ the Job resource or in the Pool, but it must be specified in
+ one or the other. If not configuration error will result.
+
+\item [Use Volume Once = \lt{}yes|no\gt{}]
+ \index[dir]{Use Volume Once}
+ \index[dir]{Directive!Use Volume Once}
+ This directive if set to {\bf yes} specifies that each volume is to be
+ used only once. This is most useful when the Media is a file and you
+ want a new file for each backup that is done. The default is {\bf no}
+ (i.e. use volume any number of times). This directive will most likely
+ be phased out (deprecated), so you are recommended to use {\bf Maximum
+ Volume Jobs = 1} instead.
+
+ The value defined by this directive in the bacula-dir.conf file is the
+ default value used when a Volume is created. Once the volume is
+ created, changing the value in the bacula-dir.conf file will not change
+ what is stored for the Volume. To change the value for an existing
+ Volume you must use the {\bf update} command in the Console.
+
+ Please see the notes below under {\bf Maximum Volume Jobs} concerning
+ using this directive with multiple simultaneous jobs.
+
+\item [Maximum Volume Jobs = \lt{}positive-integer\gt{}]
+ \index[dir]{Maximum Volume Jobs}
+ \index[dir]{Directive!Maximum Volume Jobs}
+ This directive specifies the maximum number of Jobs that can be written
+ to the Volume. If you specify zero (the default), there is no limit.
+ Otherwise, when the number of Jobs backed up to the Volume equals {\bf
+ positive-integer} the Volume will be marked {\bf Used}. When the Volume
+ is marked {\bf Used} it can no longer be used for appending Jobs, much
+ like the {\bf Full} status but it can be recycled if recycling is
+ enabled, and thus used again. By setting {\bf MaximumVolumeJobs} to
+ one, you get the same effect as setting {\bf UseVolumeOnce = yes}.
+
+ The value defined by this directive in the bacula-dir.conf
+ file is the default value used when a Volume is created. Once the volume is
+ created, changing the value in the bacula-dir.conf file will not change what
+ is stored for the Volume. To change the value for an existing Volume you
+ must use the {\bf update} command in the Console.
+
+ If you are running multiple simultaneous jobs, this directive may not
+ work correctly because when a drive is reserved for a job, this
+ directive is not taken into account, so multiple jobs may try to
+ start writing to the Volume. At some point, when the Media record is
+ updated, multiple simultaneous jobs may fail since the Volume can no
+ longer be written.
+
+\item [Maximum Volume Files = \lt{}positive-integer\gt{}]
+ \index[dir]{Maximum Volume Files}
+ \index[dir]{Directive!Maximum Volume Files}
+ This directive specifies the maximum number of files that can be written
+ to the Volume. If you specify zero (the default), there is no limit.
+ Otherwise, when the number of files written to the Volume equals {\bf
+ positive-integer} the Volume will be marked {\bf Used}. When the Volume
+ is marked {\bf Used} it can no longer be used for appending Jobs, much
+ like the {\bf Full} status but it can be recycled if recycling is
+ enabled and thus used again. This value is checked and the {\bf Used}
+ status is set only at the end of a job that writes to the particular
+ volume.
+
+ The value defined by this directive in the bacula-dir.conf file is the
+ default value used when a Volume is created. Once the volume is
+ created, changing the value in the bacula-dir.conf file will not change
+ what is stored for the Volume. To change the value for an existing
+ Volume you must use the {\bf update} command in the Console.
+
+\item [Maximum Volume Bytes = \lt{}size\gt{}]
+ \index[dir]{Maximum Volume Bytes}
+ \index[dir]{Directive!Maximum Volume Bytes}
+ This directive specifies the maximum number of bytes that can be written
+ to the Volume. If you specify zero (the default), there is no limit
+ except the physical size of the Volume. Otherwise, when the number of
+ bytes written to the Volume equals {\bf size} the Volume will be marked
+ {\bf Used}. When the Volume is marked {\bf Used} it can no longer be
+ used for appending Jobs, much like the {\bf Full} status but it can be
+ recycled if recycling is enabled, and thus the Volume can be re-used
+ after recycling. This value is checked and the {\bf Used} status set
+ while the job is writing to the particular volume.
+
+ This directive is particularly useful for restricting the size
+ of disk volumes, and will work correctly even in the case of
+ multiple simultaneous jobs writing to the volume.
+
+ The value defined by this directive in the bacula-dir.conf file is the
+ default value used when a Volume is created. Once the volume is
+ created, changing the value in the bacula-dir.conf file will not change
+ what is stored for the Volume. To change the value for an existing
+ Volume you must use the {\bf update} command in the Console.
+
+\item [Volume Use Duration = \lt{}time-period-specification\gt{}]
+ \index[dir]{Volume Use Duration}
+ \index[dir]{Directive!Volume Use Duration}
+ The Volume Use Duration directive defines the time period that the
+ Volume can be written beginning from the time of first data write to the
+ Volume. If the time-period specified is zero (the default), the Volume
+ can be written indefinitely. Otherwise, the next time a job
+ runs that wants to access this Volume, and the time period from the
+ first write to the volume (the first Job written) exceeds the
+ time-period-specification, the Volume will be marked {\bf Used}, which
+ means that no more Jobs can be appended to the Volume, but it may be
+ recycled if recycling is enabled. Using the command {\bf
+ status dir} applies algorithms similar to running jobs, so
+ during such a command, the Volume status may also be changed.
+ Once the Volume is
+ recycled, it will be available for use again.
+
+ You might use this directive, for example, if you have a Volume used for
+ Incremental backups, and Volumes used for Weekly Full backups. Once the
+ Full backup is done, you will want to use a different Incremental
+ Volume. This can be accomplished by setting the Volume Use Duration for
+ the Incremental Volume to six days. I.e. it will be used for the 6
+ days following a Full save, then a different Incremental volume will be
+ used. Be careful about setting the duration to short periods such as 23
+ hours, or you might experience problems of Bacula waiting for a tape
+ over the weekend only to complete the backups Monday morning when an
+ operator mounts a new tape.
+
+ The use duration is checked and the {\bf Used} status is set only at the
+ end of a job that writes to the particular volume, which means that even
+ though the use duration may have expired, the catalog entry will not be
+ updated until the next job that uses this volume is run. This
+ directive is not intended to be used to limit volume sizes
+ and will not work correctly (i.e. will fail jobs) if the use
+ duration expires while multiple simultaneous jobs are writing
+ to the volume.
+
+ Please note that the value defined by this directive in the bacula-dir.conf
+ file is the default value used when a Volume is created. Once the volume is
+ created, changing the value in the bacula-dir.conf file will not change what
+ is stored for the Volume. To change the value for an existing Volume you
+ must use the
+ \ilink{\bf update volume}{UpdateCommand} command in the Console.
+
+\item [Catalog Files = \lt{}yes|no\gt{}]
+ \index[dir]{Catalog Files}
+ \index[dir]{Directive!Catalog Files}
+ This directive defines whether or not you want the names of the files
+ that were saved to be put into the catalog. The default is {\bf yes}.
+ The advantage of specifying {\bf Catalog Files = No} is that you will
+ have a significantly smaller Catalog database. The disadvantage is that
+ you will not be able to produce a Catalog listing of the files backed up
+ for each Job (this is often called Browsing). Also, without the File
+ entries in the catalog, you will not be able to use the Console {\bf
+ restore} command nor any other command that references File entries.
+
+\label{PoolAutoPrune}
+\item [AutoPrune = \lt{}yes|no\gt{}]
+ \index[dir]{AutoPrune}
+ \index[dir]{Directive!AutoPrune}
+ If AutoPrune is set to {\bf yes} (default), Bacula (version 1.20 or
+ greater) will automatically apply the Volume Retention period when new
+ Volume is needed and no appendable Volumes exist in the Pool. Volume
+ pruning causes expired Jobs (older than the {\bf Volume Retention}
+ period) to be deleted from the Catalog and permits possible recycling of
+ the Volume.
+
+\label{VolRetention}
+\item [Volume Retention = \lt{}time-period-specification\gt{}]
+ \index[dir]{Volume Retention}
+ \index[dir]{Directive!Volume Retention}
+ The Volume Retention directive defines the length of time that {\bf
+ Bacula} will keep records associated with the Volume in
+ the Catalog database after the End time of each Job written to the
+ Volume. When this time period expires, and if {\bf AutoPrune} is set to
+ {\bf yes} Bacula may prune (remove) Job records that are older than the
+ specified Volume Retention period if it is necessary to free up a
+ Volume. Recycling will not occur until it is absolutely necessary to
+ free up a volume (i.e. no other writable volume exists).
+ All File records associated with pruned Jobs are also
+ pruned. The time may be specified as seconds, minutes, hours, days,
+ weeks, months, quarters, or years. The {\bf Volume Retention} is
+ applied independently of the {\bf Job Retention} and the {\bf File
+ Retention} periods defined in the Client resource. This means that all
+ the retentions periods are applied in turn and that the shorter period
+ is the one that effectively takes precedence. Note, that when the {\bf
+ Volume Retention} period has been reached, and it is necessary to obtain
+ a new volume, Bacula will prune both the Job and the File records. This
+ pruning could also occur during a {\bf status dir} command because it
+ uses similar algorithms for finding the next available Volume.
+
+ It is important to know that when the Volume Retention period expires,
+ Bacula does not automatically recycle a Volume. It attempts to keep the
+ Volume data intact as long as possible before over writing the Volume.
+
+
+ By defining multiple Pools with different Volume Retention periods, you
+ may effectively have a set of tapes that is recycled weekly, another
+ Pool of tapes that is recycled monthly and so on. However, one must
+ keep in mind that if your {\bf Volume Retention} period is too short, it
+ may prune the last valid Full backup, and hence until the next Full
+ backup is done, you will not have a complete backup of your system, and
+ in addition, the next Incremental or Differential backup will be
+ promoted to a Full backup. As a consequence, the minimum {\bf Volume
+ Retention} period should be at twice the interval of your Full backups.
+ This means that if you do a Full backup once a month, the minimum Volume
+ retention period should be two months.
+
+ The default Volume retention period is 365 days, and either the default
+ or the value defined by this directive in the bacula-dir.conf file is
+ the default value used when a Volume is created. Once the volume is
+ created, changing the value in the bacula-dir.conf file will not change
+ what is stored for the Volume. To change the value for an existing
+ Volume you must use the {\bf update} command in the Console.
+
+\label{PoolScratchPool}
+\item [ScratchPool = \lt{}pool-resource-name\gt{}]
+ \index[dir]{ScrachPool}
+ \index[dir]{Directive!ScrachPool}
+ This directive permits to specify a dedicate \textsl{Scratch} for the
+ current pool. This pool will replace the special pool named \textsl{Scrach}
+ for volume selection. For more information about \textsl{Scratch} see
+ \ilink{Scratch Pool}{TheScratchPool} section of this manual. This is useful
+ when using multiple storage sharing the same mediatype or when you want to
+ dedicate volumes to a particular set of pool.
+
+\label{PoolRecyclePool}
+\item [RecyclePool = \lt{}pool-resource-name\gt{}]
+ \index[dir]{RecyclePool}
+ \index[dir]{Directive!RecyclePool}
+ This directive defines to which pool
+ the Volume will be placed (moved) when it is recycled. Without
+ this directive, a Volume will remain in the same pool when it is
+ recycled. With this directive, it can be moved automatically to any
+ existing pool during a recycle. This directive is probably most
+ useful when defined in the Scratch pool, so that volumes will
+ be recycled back into the Scratch pool. For more on the see the
+ \ilink{Scratch Pool}{TheScratchPool} section of this manual.
+
+ Although this directive is called RecyclePool, the Volume in
+ question is actually moved from its current pool to the one
+ you specify on this directive when Bacula prunes the Volume and
+ discovers that there are no records left in the catalog and hence
+ marks it as {\bf Purged}.
+
+
+\label{PoolRecycle}
+\item [Recycle = \lt{}yes|no\gt{}]
+ \index[dir]{Recycle}
+ \index[dir]{Directive!Recycle}
+ This directive specifies whether or not Purged Volumes may be recycled.
+ If it is set to {\bf yes} (default) and Bacula needs a volume but finds
+ none that are appendable, it will search for and recycle (reuse) Purged
+ Volumes (i.e. volumes with all the Jobs and Files expired and thus
+ deleted from the Catalog). If the Volume is recycled, all previous data
+ written to that Volume will be overwritten. If Recycle is set to {\bf
+ no}, the Volume will not be recycled, and hence, the data will remain
+ valid. If you want to reuse (re-write) the Volume, and the recycle flag
+ is no (0 in the catalog), you may manually set the recycle flag (update
+ command) for a Volume to be reused.
+
+ Please note that the value defined by this directive in the
+ bacula-dir.conf file is the default value used when a Volume is created.
+ Once the volume is created, changing the value in the bacula-dir.conf
+ file will not change what is stored for the Volume. To change the value
+ for an existing Volume you must use the {\bf update} command in the
+ Console.
+
+ When all Job and File records have been pruned or purged from the
+ catalog for a particular Volume, if that Volume is marked as
+ Append, Full, Used, or Error, it will then be marked as Purged. Only
+ Volumes marked as Purged will be considered to be converted to the
+ Recycled state if the {\bf Recycle} directive is set to {\bf yes}.
+
+
+\label{RecycleOldest}
+\item [Recycle Oldest Volume = \lt{}yes|no\gt{}]
+ \index[dir]{Recycle Oldest Volume}
+ \index[dir]{Directive!Recycle Oldest Volume}
+ This directive instructs the Director to search for the oldest used
+ Volume in the Pool when another Volume is requested by the Storage
+ daemon and none are available. The catalog is then {\bf pruned}
+ respecting the retention periods of all Files and Jobs written to this
+ Volume. If all Jobs are pruned (i.e. the volume is Purged), then the
+ Volume is recycled and will be used as the next Volume to be written.
+ This directive respects any Job, File, or Volume retention periods that
+ you may have specified, and as such it is {\bf much} better to use this
+ directive than the Purge Oldest Volume.
+
+ This directive can be useful if you have a fixed number of Volumes in the
+ Pool and you want to cycle through them and you have specified the correct
+ retention periods.
+
+ However, if you use this directive and have only one
+ Volume in the Pool, you will immediately recycle your Volume if you fill
+ it and Bacula needs another one. Thus your backup will be totally invalid.
+ Please use this directive with care. The default is {\bf no}.
+
+\label{RecycleCurrent}
+
+\item [Recycle Current Volume = \lt{}yes|no\gt{}]
+ \index[dir]{Recycle Current Volume}
+ \index[dir]{Directive!Recycle Current Volume}
+ If Bacula needs a new Volume, this directive instructs Bacula to Prune
+ the volume respecting the Job and File retention periods. If all Jobs
+ are pruned (i.e. the volume is Purged), then the Volume is recycled and
+ will be used as the next Volume to be written. This directive respects
+ any Job, File, or Volume retention periods that you may have specified,
+ and thus it is {\bf much} better to use it rather than the Purge Oldest
+ Volume directive.
+
+ This directive can be useful if you have: a fixed number of Volumes in
+ the Pool, you want to cycle through them, and you have specified
+ retention periods that prune Volumes before you have cycled through the
+ Volume in the Pool.
+
+ However, if you use this directive and have only one Volume in the Pool,
+ you will immediately recycle your Volume if you fill it and Bacula needs
+ another one. Thus your backup will be totally invalid. Please use this
+ directive with care. The default is {\bf no}.
+
+\label{PurgeOldest}
+
+\item [Purge Oldest Volume = \lt{}yes|no\gt{}]
+ \index[dir]{Purge Oldest Volume}
+ \index[dir]{Directive!Purge Oldest Volume}
+ This directive instructs the Director to search for the oldest used
+ Volume in the Pool when another Volume is requested by the Storage
+ daemon and none are available. The catalog is then {\bf purged}
+ irrespective of retention periods of all Files and Jobs written to this
+ Volume. The Volume is then recycled and will be used as the next Volume
+ to be written. This directive overrides any Job, File, or Volume
+ retention periods that you may have specified.
+
+ This directive can be useful if you have a fixed number of Volumes in
+ the Pool and you want to cycle through them and reusing the oldest one
+ when all Volumes are full, but you don't want to worry about setting
+ proper retention periods. However, by using this option you risk losing
+ valuable data.
+
+ Please be aware that {\bf Purge Oldest Volume} disregards all retention
+ periods. If you have only a single Volume defined and you turn this
+ variable on, that Volume will always be immediately overwritten when it
+ fills! So at a minimum, ensure that you have a decent number of Volumes
+ in your Pool before running any jobs. If you want retention periods to
+ apply do not use this directive. To specify a retention period, use the
+ {\bf Volume Retention} directive (see above).
+
+ We {\bf highly} recommend against using this directive, because it is
+ sure that some day, Bacula will recycle a Volume that contains current
+ data. The default is {\bf no}.
+
+\item [Cleaning Prefix = \lt{}string\gt{}]
+ \index[dir]{Cleaning Prefix}
+ \index[dir]{Directive!Cleaning Prefix}
+ This directive defines a prefix string, which if it matches the
+ beginning of a Volume name during labeling of a Volume, the Volume will
+ be defined with the VolStatus set to {\bf Cleaning} and thus Bacula will
+ never attempt to use this tape. This is primarily for use with
+ autochangers that accept barcodes where the convention is that barcodes
+ beginning with {\bf CLN} are treated as cleaning tapes.
+
+\label{Label}
+\item [Label Format = \lt{}format\gt{}]
+ \index[dir]{Label Format}
+ \index[dir]{Directive!Label Format}
+ This directive specifies the format of the labels contained in this
+ pool. The format directive is used as a sort of template to create new
+ Volume names during automatic Volume labeling.
+
+ The {\bf format} should be specified in double quotes, and consists of
+ letters, numbers and the special characters hyphen ({\bf -}), underscore
+ ({\bf \_}), colon ({\bf :}), and period ({\bf .}), which are the legal
+ characters for a Volume name. The {\bf format} should be enclosed in
+ double quotes (").
+
+ In addition, the format may contain a number of variable expansion
+ characters which will be expanded by a complex algorithm allowing you to
+ create Volume names of many different formats. In all cases, the
+ expansion process must resolve to the set of characters noted above that
+ are legal Volume names. Generally, these variable expansion characters
+ begin with a dollar sign ({\bf \$}) or a left bracket ({\bf [}). If you
+ specify variable expansion characters, you should always enclose the
+ format with double quote characters ({\bf "}). For more details on
+ variable expansion, please see the \ilink{Variable
+ Expansion}{VarsChapter} Chapter of this manual.
+
+ If no variable expansion characters are found in the string, the Volume
+ name will be formed from the {\bf format} string appended with the
+ a unique number that increases. If you do not remove volumes from the
+ pool, this number should be the number of volumes plus one, but this
+ is not guaranteed. The unique number will be edited as four
+ digits with leading zeros. For example, with a {\bf Label Format =
+ "File-"}, the first volumes will be named {\bf File-0001}, {\bf
+ File-0002}, ...
+
+ With the exception of Job specific variables, you can test your {\bf
+ LabelFormat} by using the \ilink{ var command}{var} the Console Chapter
+ of this manual.
+
+ In almost all cases, you should enclose the format specification (part
+ after the equal sign) in double quotes. Please note that this directive
+ is deprecated and is replaced in version 1.37 and greater with a Python
+ script for creating volume names.
+
+\end{description}
+
+In order for a Pool to be used during a Backup Job, the Pool must have at
+least one Volume associated with it. Volumes are created for a Pool using
+the {\bf label} or the {\bf add} commands in the {\bf Bacula Console},
+program. In addition to adding Volumes to the Pool (i.e. putting the
+Volume names in the Catalog database), the physical Volume must be labeled
+with a valid Bacula software volume label before {\bf Bacula} will accept
+the Volume. This will be automatically done if you use the {\bf label}
+command. Bacula can automatically label Volumes if instructed to do so,
+but this feature is not yet fully implemented.
+
+The following is an example of a valid Pool resource definition:
+
+\footnotesize
+\begin{verbatim}
+
+Pool {
+ Name = Default
+ Pool Type = Backup
+}
+\end{verbatim}
+\normalsize
+
+\subsection{The Scratch Pool}
+\label{TheScratchPool}
+\index[general]{Scratch Pool}
+In general, you can give your Pools any name you wish, but there is one
+important restriction: the Pool named {\bf Scratch}, if it exists behaves
+like a scratch pool of Volumes in that when Bacula needs a new Volume for
+writing and it cannot find one, it will look in the Scratch pool, and if
+it finds an available Volume, it will move it out of the Scratch pool into
+the Pool currently being used by the job.
+
+
+\section{The Catalog Resource}
+\label{CatalogResource}
+\index[general]{Resource!Catalog}
+\index[general]{Catalog Resource}
+
+The Catalog Resource defines what catalog to use for the current job.
+Currently, Bacula can only handle a single database server (SQLite, MySQL,
+PostgreSQL) that is defined when configuring {\bf Bacula}. However, there
+may be as many Catalogs (databases) defined as you wish. For example, you
+may want each Client to have its own Catalog database, or you may want
+backup jobs to use one database and verify or restore jobs to use another
+database.
+
+Since SQLite is compiled in, it always runs on the same machine
+as the Director and the database must be directly accessible (mounted) from
+the Director. However, since both MySQL and PostgreSQL are networked
+databases, they may reside either on the same machine as the Director
+or on a different machine on the network. See below for more details.
+
+\begin{description}
+
+\item [Catalog]
+ \index[dir]{Catalog}
+ \index[dir]{Directive!Catalog}
+ Start of the Catalog resource. At least one Catalog resource must be
+defined.
+
+
+\item [Name = \lt{}name\gt{}]
+ \index[dir]{Name}
+ \index[dir]{Directive!Name}
+ The name of the Catalog. No necessary relation to the database server
+ name. This name will be specified in the Client resource directive
+ indicating that all catalog data for that Client is maintained in this
+ Catalog. This directive is required.
+
+\item [password = \lt{}password\gt{}]
+ \index[dir]{password}
+ \index[dir]{Directive!password}
+ This specifies the password to use when logging into the database. This
+ directive is required.
+
+\item [DB Name = \lt{}name\gt{}]
+ \index[dir]{DB Name}
+ \index[dir]{Directive!DB Name}
+ This specifies the name of the database. If you use multiple catalogs
+ (databases), you specify which one here. If you are using an external
+ database server rather than the internal one, you must specify a name
+ that is known to the server (i.e. you explicitly created the Bacula
+ tables using this name. This directive is required.
+
+\item [user = \lt{}user\gt{}]
+ \index[dir]{user}
+ \index[dir]{Directive!user}
+ This specifies what user name to use to log into the database. This
+ directive is required.
+
+\item [DB Socket = \lt{}socket-name\gt{}]
+ \index[dir]{DB Socket}
+ \index[dir]{Directive!DB Socket}
+ This is the name of a socket to use on the local host to connect to the
+ database. This directive is used only by MySQL and is ignored by SQLite.
+ Normally, if neither {\bf DB Socket} or {\bf DB Address} are specified, MySQL
+ will use the default socket. If the DB Socket is specified, the
+ MySQL server must reside on the same machine as the Director.
+
+\item [DB Address = \lt{}address\gt{}]
+ \index[dir]{DB Address}
+ \index[dir]{Directive!DB Address}
+ This is the host address of the database server. Normally, you would specify
+ this instead of {\bf DB Socket} if the database server is on another machine.
+ In that case, you will also specify {\bf DB Port}. This directive is used
+ only by MySQL and PostgreSQL and is ignored by SQLite if provided.
+ This directive is optional.
+
+\item [DB Port = \lt{}port\gt{}]
+ \index[dir]{DB Port}
+ \index[dir]{Directive!DB Port}
+ This defines the port to be used in conjunction with {\bf DB Address} to
+ access the database if it is on another machine. This directive is used only
+ by MySQL and PostgreSQL and is ignored by SQLite if provided. This
+ directive is optional.
+
+%% \item [Multiple Connections = \lt{}yes|no\gt{}]
+%% \index[dir]{Multiple Connections}
+%% \index[dir]{Directive!Multiple Connections}
+%% By default, this directive is set to no. In that case, each job that uses
+the
+%% same Catalog will use a single connection to the catalog. It will be shared,
+%% and Bacula will allow only one Job at a time to communicate. If you set this
+%% directive to yes, Bacula will permit multiple connections to the database,
+%% and the database must be multi-thread capable. For SQLite and PostgreSQL,
+%% this is no problem. For MySQL, you must be *very* careful to have the
+%% multi-thread version of the client library loaded on your system. When this
+%% directive is set yes, each Job will have a separate connection to the
+%% database, and the database will control the interaction between the
+different
+%% Jobs. This can significantly speed up the database operations if you are
+%% running multiple simultaneous jobs. In addition, for SQLite and PostgreSQL,
+%% Bacula will automatically enable transactions. This can significantly speed
+%% up insertion of attributes in the database either for a single Job or
+%% multiple simultaneous Jobs.
+
+%% This directive has not been tested. Please test carefully before running it
+%% in production and report back your results.
+

+\section{The Messages Resource}
+\label{MessagesResource2}
+\index[general]{Resource!Messages}
+\index[general]{Messages Resource}
+
+For the details of the Messages Resource, please see the
+\ilink{Messages Resource Chapter}{MessagesChapter} of this
+manual.
+
+\section{The Console Resource}
+\label{ConsoleResource1}
+\index[general]{Console Resource}
+\index[general]{Resource!Console}
+
+As of Bacula version 1.33 and higher, there are three different kinds of
+consoles, which the administrator or user can use to interact with the
+Director. These three kinds of consoles comprise three different security
+levels.
+
+\begin{itemize}
+\item The first console type is an {\bf anonymous} or {\bf default} console,
+ which has full privileges. There is no console resource necessary for
+ this type since the password is specified in the Director's resource and
+ consequently such consoles do not have a name as defined on a {\bf Name
+ =} directive. This is the kind of console that was initially
+ implemented in versions prior to 1.33 and remains valid. Typically you
+ would use it only for administrators.
+
+\item The second type of console, and new to version 1.33 and higher is a
+ "named" console defined within a Console resource in both the Director's
+ configuration file and in the Console's configuration file. Both the
+ names and the passwords in these two entries must match much as is the
+ case for Client programs.
+
+ This second type of console begins with absolutely no privileges except
+ those explicitly specified in the Director's Console resource. Thus you
+ can have multiple Consoles with different names and passwords, sort of
+ like multiple users, each with different privileges. As a default,
+ these consoles can do absolutely nothing -- no commands whatsoever. You
+ give them privileges or rather access to commands and resources by
+ specifying access control lists in the Director's Console resource. The
+ ACLs are specified by a directive followed by a list of access names.
+ Examples of this are shown below.
+
+\item The third type of console is similar to the above mentioned one in that
+ it requires a Console resource definition in both the Director and the
+ Console. In addition, if the console name, provided on the {\bf Name =}
+ directive, is the same as a Client name, that console is permitted to
+ use the {\bf SetIP} command to change the Address directive in the
+ Director's client resource to the IP address of the Console. This
+ permits portables or other machines using DHCP (non-fixed IP addresses)
+ to "notify" the Director of their current IP address.
+\end{itemize}
+
+The Console resource is optional and need not be specified. The following
+directives are permitted within the Director's configuration resource:
+
+\begin{description}
+
+\item [Name = \lt{}name\gt{}]
+ \index[dir]{Name}
+ \index[dir]{Directive!Name}
+ The name of the console. This name must match the name specified in the
+Console's configuration resource (much as is the case with Client
+definitions).
+
+\item [Password = \lt{}password\gt{}]
+ \index[dir]{Password}
+ \index[dir]{Directive!Password}
+ Specifies the password that must be supplied for a named Bacula Console
+ to be authorized. The same password must appear in the {\bf Console}
+ resource of the Console configuration file. For added security, the
+ password is never actually passed across the network but rather a
+ challenge response hash code created with the password. This directive
+ is required. If you have either {\bf /dev/random} {\bf bc} on your
+ machine, Bacula will generate a random password during the configuration
+ process, otherwise it will be left blank.
+
+ The password is plain text. It is not generated through any special
+ process. However, it is preferable for security reasons to choose
+ random text.
+
+\item [JobACL = \lt{}name-list\gt{}]
+ \index[dir]{JobACL}
+ \index[dir]{Directive!JobACL}
+ This directive is used to specify a list of Job resource names that can
+ be accessed by the console. Without this directive, the console cannot
+ access any of the Director's Job resources. Multiple Job resource names
+ may be specified by separating them with commas, and/or by specifying
+ multiple JobACL directives. For example, the directive may be specified
+ as:
+
+\footnotesize
+\begin{verbatim}
+ JobACL = kernsave, "Backup client 1", "Backup client 2"
+ JobACL = "RestoreFiles"
+
+\end{verbatim}
+\normalsize
+
+With the above specification, the console can access the Director's resources
+for the four jobs named on the JobACL directives, but for no others.
+
+\item [ClientACL = \lt{}name-list\gt{}]
+ \index[dir]{ClientACL}
+ \index[dir]{Directive!ClientACL}
+ This directive is used to specify a list of Client resource names that can
+be
+accessed by the console.
+
+\item [StorageACL = \lt{}name-list\gt{}]
+ \index[dir]{StorageACL}
+ \index[dir]{Directive!StorageACL}
+ This directive is used to specify a list of Storage resource names that can
+be accessed by the console.
+
+\item [ScheduleACL = \lt{}name-list\gt{}]
+ \index[dir]{ScheduleACL}
+ \index[dir]{Directive!ScheduleACL}
+ This directive is used to specify a list of Schedule resource names that can
+ be accessed by the console.
+
+\item [PoolACL = \lt{}name-list\gt{}]
+ \index[dir]{PoolACL}
+ \index[dir]{Directive!PoolACL}
+ This directive is used to specify a list of Pool resource names that can be
+ accessed by the console.
+
+\item [FileSetACL = \lt{}name-list\gt{}]
+ \index[dir]{FileSetACL}
+ \index[dir]{Directive!FileSetACL}
+ This directive is used to specify a list of FileSet resource names that
+ can be accessed by the console.
+
+\item [CatalogACL = \lt{}name-list\gt{}]
+ \index[dir]{CatalogACL}
+ \index[dir]{Directive!CatalogACL}
+ This directive is used to specify a list of Catalog resource names that
+ can be accessed by the console.
+
+\item [CommandACL = \lt{}name-list\gt{}]
+ \index[dir]{CommandACL}
+ \index[dir]{Directive!CommandACL}
+ This directive is used to specify a list of of console commands that can
+ be executed by the console.
+
+\item [WhereACL = \lt{}string\gt{}]
+ \index[dir]{WhereACL}
+ \index[dir]{Directive!WhereACL}
+ This directive permits you to specify where a restricted console
+ can restore files. If this directive is not specified, only the
+ default restore location is permitted (normally {\bf
+ /tmp/bacula-restores}. If {\bf *all*} is specified any path the
+ user enters will be accepted (not very secure), any other
+ value specified (there may be multiple WhereACL directives) will
+ restrict the user to use that path. For example, on a Unix system,
+ if you specify "/", the file will be restored to the original
+ location. This directive is untested.
+
+\end{description}
+
+Aside from Director resource names and console command names, the special
+keyword {\bf *all*} can be specified in any of the above access control lists.
+When this keyword is present, any resource or command name (which ever is
+appropriate) will be accepted. For an example configuration file, please see
+the
+\ilink{Console Configuration}{ConsoleConfChapter} chapter of this
+manual.
+
+\section{The Counter Resource}
+\label{CounterResource}
+\index[general]{Resource!Counter}
+\index[general]{Counter Resource}
+
+The Counter Resource defines a counter variable that can be accessed by
+variable expansion used for creating Volume labels with the {\bf LabelFormat}
+directive. See the
+\ilink{LabelFormat}{Label} directive in this chapter for more
+details.
+
+\begin{description}
+
+\item [Counter]
+ \index[dir]{Counter}
+ \index[dir]{Directive!Counter}
+ Start of the Counter resource. Counter directives are optional.
+
+\item [Name = \lt{}name\gt{}]
+ \index[dir]{Name}
+ \index[dir]{Directive!Name}
+ The name of the Counter. This is the name you will use in the variable
+expansion to reference the counter value.
+
+\item [Minimum = \lt{}integer\gt{}]
+ \index[dir]{Minimum}
+ \index[dir]{Directive!Minimum}
+ This specifies the minimum value that the counter can have. It also becomes
+the default. If not supplied, zero is assumed.
+
+\item [Maximum = \lt{}integer\gt{}]
+ \index[dir]{Maximum}
+ \index[dir]{Directive!Maximum}
+ \index[dir]{Directive!Maximum}
+ This is the maximum value value that the counter can have. If not specified
+or set to zero, the counter can have a maximum value of 2,147,483,648 (2 to
+the 31 power). When the counter is incremented past this value, it is reset
+to the Minimum.
+
+\item [*WrapCounter = \lt{}counter-name\gt{}]
+ \index[dir]{*WrapCounter}
+ \index[dir]{Directive!*WrapCounter}
+ If this value is specified, when the counter is incremented past the
+maximum
+and thus reset to the minimum, the counter specified on the {\bf WrapCounter}
+is incremented. (This is not currently implemented).
+
+\item [Catalog = \lt{}catalog-name\gt{}]
+ \index[dir]{Catalog}
+ \index[dir]{Directive!Catalog}
+ If this directive is specified, the counter and its values will be saved in
+the specified catalog. If this directive is not present, the counter will be
+redefined each time that Bacula is started.
+\end{description}

+\chapter{Client/File daemon Configuration}
+\label{FiledConfChapter}
+\index[general]{Configuration!Client/File daemon }
+\index[general]{Client/File daemon Configuration }
+
+The Client (or File Daemon) Configuration is one of the simpler ones to
+specify. Generally, other than changing the Client name so that error messages
+are easily identified, you will not need to modify the default Client
+configuration file.
+
+For a general discussion of configuration file and resources including the
+data types recognized by {\bf Bacula}, please see the
+\ilink{Configuration}{ConfigureChapter} chapter of this manual. The
+following Client Resource definitions must be defined:
+
+\begin{itemize}
+\item
+ \ilink{Client}{ClientResource} -- to define what Clients are to
+ be backed up.
+\item
+ \ilink{Director}{DirectorResource} -- to define the Director's
+ name and its access password.
+\item
+ \ilink{Messages}{MessagesChapter} -- to define where error and
+ information messages are to be sent.
+\end{itemize}
+
+\section{The Client Resource}
+\label{ClientResource}
+\index[general]{Resource!Client }
+\index[general]{Client Resource }
+
+The Client Resource (or FileDaemon) resource defines the name of the Client
+(as used by the Director) as well as the port on which the Client listens for
+Director connections.
+
+\begin{description}
+
+\item [Client (or FileDaemon)]
+ \index[fd]{Client (or FileDaemon)}
+ \index[fd]{Directive!Client (or FileDaemon)}
+ Start of the Client records. There must be one and only one Client resource
+ in the configuration file, since it defines the properties of the current
+ client program.
+
+\item [Name = \lt{}name\gt{}]
+ \index[fd]{Name}
+ \index[fd]{Directive!Name}
+ The client name that must be used by the Director when connecting. Generally,
+ it is a good idea to use a name related to the machine so that error messages
+ can be easily identified if you have multiple Clients. This directive is
+ required.
+
+\item [Working Directory = \lt{}Directory\gt{}]
+ \index[fd]{Working Directory}
+ \index[fd]{Directive!Working Directory}
+ This directive is mandatory and specifies a directory in which the File
+ daemon may put its status files. This directory should be used only by {\bf
+ Bacula}, but may be shared by other Bacula daemons provided the daemon
+ names on the {\bf Name} definition are unique for each daemon. This directive
+ is required.
+
+ On Win32 systems, in some circumstances you may need to specify a drive
+ letter in the specified working directory path. Also, please be sure
+ that this directory is writable by the SYSTEM user otherwise restores
+ may fail (the bootstrap file that is transferred to the File daemon from
+ the Director is temporarily put in this directory before being passed
+ to the Storage daemon).
+
+\item [Pid Directory = \lt{}Directory\gt{}]
+ \index[fd]{Pid Directory}
+ \index[fd]{Directive!Pid Directory}
+ This directive is mandatory and specifies a directory in which the Director
+ may put its process Id file files. The process Id file is used to shutdown
+ Bacula and to prevent multiple copies of Bacula from running simultaneously.
+ This record is required. Standard shell expansion of the {\bf Directory} is
+ done when the configuration file is read so that values such as {\bf \$HOME}
+ will be properly expanded.
+
+ Typically on Linux systems, you will set this to: {\bf /var/run}. If you are
+ not installing Bacula in the system directories, you can use the {\bf Working
+ Directory} as defined above.
+
+\item [Heartbeat Interval = \lt{}time-interval\gt{}]
+ \index[fd]{Heartbeat Interval}
+ \index[fd]{Directive!Heartbeat Interval}
+ \index[general]{Heartbeat Interval}
+ \index[general]{Broken pipe}
+ \index[general]{slow}
+ \index[general]{Backups!slow}
+ This record defines an interval of time in seconds. For each heartbeat that the
+ File daemon receives from the Storage daemon, it will forward it to the
+ Director. In addition, if no heartbeat has been received from the
+ Storage daemon and thus forwarded the File daemon will send a heartbeat
+ signal to the Director and to the Storage daemon to keep the channels
+ active. The default interval is zero which disables the heartbeat.
+ This feature is particularly useful if you have a router such as 3Com
+ that does not follow Internet standards and times out a valid
+ connection after a short duration despite the fact that keepalive is
+ set. This usually results in a broken pipe error message.
+
+ If you continue getting broken pipe error messages despite using the
+ Heartbeat Interval, and you are using Windows, you should consider
+ upgrading your ethernet driver. This is a known problem with NVidia
+ NForce 3 drivers (4.4.2 17/05/2004), or try the following workaround
+ suggested by Thomas Simmons for Win32 machines:
+
+ Browse to:
+ Start \gt{} Control Panel \gt{} Network Connections
+
+ Right click the connection for the nvidia adapter and select properties.
+ Under the General tab, click "Configure...". Under the Advanced tab set
+ "Checksum Offload" to disabled and click OK to save the change.
+
+ Lack of communications, or communications that get interrupted can
+ also be caused by Linux firewalls where you have a rule that throttles
+ connections or traffic.
+
+
+\item [Maximum Concurrent Jobs = \lt{}number\gt{}]
+ \index[fd]{Maximum Concurrent Jobs}
+ \index[fd]{Directive!Maximum Concurrent Jobs}
+ where \lt{}number\gt{} is the maximum number of Jobs that should run
+ concurrently. The default is set to 2, but you may set it to a larger
+ number. Each contact from the Director (e.g. status request, job start
+ request) is considered as a Job, so if you want to be able to do a {\bf
+ status} request in the console at the same time as a Job is running, you
+ will need to set this value greater than 1.
+
+\item [FDAddresses = \lt{}IP-address-specification\gt{}]
+ \index[fd]{FDAddresses}
+ \index[fd]{Directive!FDAddresses}
+ Specify the ports and addresses on which the File daemon listens for
+ Director connections. Probably the simplest way to explain is to show
+ an example:
+
+\footnotesize
+\begin{verbatim}
+ FDAddresses = {
+ ip = { addr = 1.2.3.4; port = 1205; }
+ ipv4 = {
+ addr = 1.2.3.4; port = http; }
+ ipv6 = {
+ addr = 1.2.3.4;
+ port = 1205;
+ }
+ ip = {
+ addr = 1.2.3.4
+ port = 1205
+ }
+ ip = { addr = 1.2.3.4 }
+ ip = {
+ addr = 201:220:222::2
+ }
+ ip = {
+ addr = bluedot.thun.net
+ }
+ }
+\end{verbatim}
+\normalsize
+
+where ip, ip4, ip6, addr, and port are all keywords. Note, that the address
+can be specified as either a dotted quadruple, or IPv6 colon notation, or as
+a symbolic name (only in the ip specification). Also, port can be specified
+as a number or as the mnemonic value from the /etc/services file. If a port
+is not specified, the default will be used. If an ip section is specified,
+the resolution can be made either by IPv4 or IPv6. If ip4 is specified, then
+only IPv4 resolutions will be permitted, and likewise with ip6.
+
+\item [FDPort = \lt{}port-number\gt{}]
+ \index[fd]{FDPort}
+ \index[fd]{Directive!FDPort}
+ This specifies the port number on which the Client listens for Director
+ connections. It must agree with the FDPort specified in the Client resource
+ of the Director's configuration file. The default is 9102.
+
+\item [FDAddress = \lt{}IP-Address\gt{}]
+ \index[fd]{FDAddress}
+ \index[fd]{Directive!FDAddress}
+ This record is optional, and if it is specified, it will cause the File
+ daemon server (for Director connections) to bind to the specified {\bf
+ IP-Address}, which is either a domain name or an IP address specified as a
+ dotted quadruple. If this record is not specified, the File daemon will bind
+ to any available address (the default).
+
+\item [FDSourceAddress = \lt{}IP-Address\gt{}]
+ \index[fd]{FDSourceAddress}
+ \index[fd]{Directive!FDSourceAddress}
+ This record is optional, and if it is specified, it will cause the File
+ daemon server (for Storage connections) to bind to the specified {\bf
+ IP-Address}, which is either a domain name or an IP address specified as a
+ dotted quadruple. If this record is not specified, the kernel will choose
+ the best address according to the routing table (the default).
+
+\item [SDConnectTimeout = \lt{}time-interval\gt{}]
+ \index[fd]{SDConnectTimeout}
+ \index[fd]{Directive!SDConnectTimeout}
+ This record defines an interval of time that the File daemon will try to
+ connect to the Storage daemon. The default is 30 minutes. If no connection
+ is made in the specified time interval, the File daemon cancels the Job.
+
+\item [Maximum Network Buffer Size = \lt{}bytes\gt{}]
+ \index[fd]{Maximum Network Buffer Size}
+ \index[fd]{Directive!Maximum Network Buffer Size}
+ where \lt{}bytes\gt{} specifies the initial network buffer size to use with
+ the File daemon. This size will be adjusted down if it is too large until it
+ is accepted by the OS. Please use care in setting this value since if it is
+ too large, it will be trimmed by 512 bytes until the OS is happy, which may
+ require a large number of system calls. The default value is 65,536 bytes.
+
+ Note, on certain Windows machines, there are reports that the
+ transfer rates are very slow and this seems to be related to
+ the default 65,536 size. On systems where the transfer rates
+ seem abnormally slow compared to other systems, you might try
+ setting the Maximum Network Buffer Size to 32,768 in both the
+ File daemon and in the Storage daemon.
+
+\item [Heartbeat Interval = \lt{}time-interval\gt{}]
+ \index[console]{Heartbeat Interval}
+ \index[console]{Directive!Heartbeat}
+ This directive is optional and if specified will cause the File daemon to
+ set a keepalive interval (heartbeat) in seconds on each of the sockets
+ to communicate with the Storage daemon. It is implemented only on systems
+ (Linux, ...) that provide the {\bf setsockopt} TCP\_KEEPIDLE function.
+ The default value is zero, which means no change is made to the socket.
+
+
+\item [PKI Encryption]
+ See the \ilink{Data Encryption}{DataEncryption} chapter of this manual.
+
+\item [PKI Signatures]
+ See the \ilink{Data Encryption}{DataEncryption} chapter of this manual.
+
+\item [PKI Keypair]
+ See the \ilink{Data Encryption}{DataEncryption} chapter of this manual.
+
+\item [PKI Master Key]
+ See the \ilink{Data Encryption}{DataEncryption} chapter of this manual.
+
+\end{description}
+
+The following is an example of a valid Client resource definition:
+
+\footnotesize
+\begin{verbatim}
+Client { # this is me
+ Name = rufus-fd
+ WorkingDirectory = $HOME/bacula/bin/working
+ Pid Directory = $HOME/bacula/bin/working
+}
+\end{verbatim}
+\normalsize
+
+\section{The Director Resource}
+\label{DirectorResource}
+\index[general]{Director Resource }
+\index[general]{Resource!Director }
+
+The Director resource defines the name and password of the Directors that are
+permitted to contact this Client.
+
+\begin{description}
+
+\item [Director]
+ \index[fd]{Director}
+ \index[fd]{Directive!Director}
+ Start of the Director records. There may be any number of Director resources
+ in the Client configuration file. Each one specifies a Director that is
+ allowed to connect to this Client.
+
+\item [Name = \lt{}name\gt{}]
+ \index[fd]{Name}
+ \index[fd]{Directive!Name}
+ The name of the Director that may contact this Client. This name must be the
+ same as the name specified on the Director resource in the Director's
+ configuration file. Note, the case (upper/lower) of the characters in
+ the name are significant (i.e. S is not the same as s). This directive
+ is required.
+
+\item [Password = \lt{}password\gt{}]
+ \index[fd]{Password}
+ \index[fd]{Directive!Password}
+ Specifies the password that must be supplied for a Director to be authorized.
+This password must be the same as the password specified in the Client
+resource in the Director's configuration file. This directive is required.
+
+\item [Monitor = \lt{}yes|no\gt{}]
+ \index[fd]{Monitor}
+ \index[fd]{Directive!Monitor}
+ If Monitor is set to {\bf no} (default), this director will have full access
+ to this Client. If Monitor is set to {\bf yes}, this director will only be
+ able to fetch the current status of this Client.
+
+ Please note that if this director is being used by a Monitor, we highly
+ recommend to set this directive to {\bf yes} to avoid serious security
+ problems.
+\end{description}
+
+Thus multiple Directors may be authorized to use this Client's services. Each
+Director will have a different name, and normally a different password as
+well.
+
+The following is an example of a valid Director resource definition:
+
+\footnotesize
+\begin{verbatim}
+#
+# List Directors who are permitted to contact the File daemon
+#
+Director {
+ Name = HeadMan
+ Password = very_good # password HeadMan must supply
+}
+Director {
+ Name = Worker
+ Password = not_as_good
+ Monitor = Yes
+}
+\end{verbatim}
+\normalsize
+
+\section{The Message Resource}
+\label{MessagesResource3}
+\index[general]{Message Resource}
+\index[general]{Resource!Message }
+
+Please see the
+\ilink{Messages Resource}{MessagesChapter} Chapter of this
+manual for the details of the Messages Resource.
+
+There must be at least one Message resource in the Client configuration file.
+
+\section{Example Client Configuration File}
+\label{SampleClientConfiguration}
+\index[general]{Example Client Configuration File }
+\index[general]{File!Example Client Configuration }
+
+An example File Daemon configuration file might be the following:
+
+\footnotesize
+\begin{verbatim}
+#
+# Default Bacula File Daemon Configuration file
+#
+# For Bacula release 1.35.2 (16 August 2004) -- gentoo 1.4.16

+
+\section{The FileSet Resource}
+\label{FileSetResource}
+\index[general]{Resource!FileSet}
+\index[general]{FileSet Resource}
+
+The FileSet resource defines what files are to be included or excluded in a
+backup job. A {\bf FileSet} resource is required for each backup Job. It
+consists of a list of files or directories to be included, a list of files
+or directories to be excluded and the various backup options such as
+compression, encryption, and signatures that are to be applied to each
+file.
+
+Any change to the list of the included files will cause Bacula to
+automatically create a new FileSet (defined by the name and an MD5 checksum
+of the Include/Exclude contents). Each time a new FileSet is created,
+Bacula will ensure that the next backup is always a Full save.
+
+Bacula is designed to handle most character sets of the world,
+US ASCII, German, French, Chinese, ... However, it does this by
+encoding everything in UTF-8, and it expects all configuration files
+(including those read on Win32 machines) to be in UTF-8 format.
+UTF-8 is typically the default on Linux machines, but not on all
+Unix machines, nor on Windows, so you must take some care to ensure
+that your locale is set properly before starting Bacula.
+On most modern Win32 machines, you can edit the conf files with {\bf
+notebook} and choose output encoding UTF-8.
+
+To ensure that Bacula configuration files can be correctly read including
+foreign characters the {bf LANG} environment variable
+must end in {\bf .UTF-8}. An full example is {\bf en\_US.UTF-8}. The
+exact syntax may vary a bit from OS to OS, and exactly how you define
+it will also vary.
+
+Bacula assumes that all filenames are in UTF-8 format on Linux and
+Unix machines. On Win32 they are in Unicode (UTF-16), and will
+be automatically converted to UTF-8 format.
+
+
+\begin{description}
+
+\item [FileSet]
+\index[dir]{FileSet}
+\index[dir]{Directive!FileSet}
+Start of the FileSet resource. One {\bf FileSet} resource must be
+defined for each Backup job.
+
+\item [Name = \lt{}name\gt{}]
+\index[dir]{Name}
+\index[dir]{Directive!Name}
+ The name of the FileSet resource. This directive is required.
+
+\item [Ignore FileSet Changes = \lt{}yes|no\gt{}]
+\index[dir]{Ignore FileSet Changes}
+\index[dir]{Directive!Ignore FileSet Changes}
+ Normally, if you modify the FileSet Include or Exclude lists,
+ the next backup will be forced to a Full so that Bacula can
+ guarantee that any additions or deletions are properly saved.
+
+ We strongly recommend against setting this directive to yes,
+ since doing so may cause you to have an incomplete set of backups.
+
+ If this directive is set to {\bf yes}, any changes you make to the
+ FileSet Include or Exclude lists, will not force a Full during
+ subsequent backups.
+
+ The default is {\bf no}, in which case, if you change the Include or
+ Exclude, Bacula will force a Full backup to ensure that everything is
+ properly backed up.
+
+\item [Enable VSS = \lt{}yes|no\gt{}]
+\index[dir]{Enable VSS}
+\index[dir]{Directive!Enable VSS}
+ If this directive is set to {\bf yes} the File daemon will be notified
+ that the user wants to use a Volume Shadow Copy Service (VSS) backup
+ for this job. The default is {\bf yes}. This directive is effective
+ only for VSS enabled Win32 File daemons. It permits a consistent copy
+ of open files to be made for cooperating writer applications, and for
+ applications that are not VSS away, Bacula can at least copy open files.
+ For more information, please see the
+ \ilink{Windows}{VSS} chapter of this manual.
+
+
+\item [Include \{ Options \{\lt{}file-options\gt{}\} ...;
+ \lt{}file-list\gt{} \} ]
+\index[dir]{Include \{ [ Options \{\lt{}file-options\gt{}\} ...]
+ \lt{}file-list\gt{} \} }
+\index[dir]{Directive!Include}
+
+\item [Options \{ \lt{}file-options\gt{} \} ]
+\index[dir]{Options \{ \lt{}file-options\gt{} \} }
+
+\item [Exclude \{ \lt{}file-list\gt{} \}]
+\index[dir]{Exclude \{ \lt{}file-list\gt{} \} }
+\index[dir]{Directive!Exclude}
+
+
+\end{description}
+
+The Include resource must contain a list of directories and/or files to be
+processed in the backup job. Normally, all files found in all
+subdirectories of any directory in the Include File list will be backed up.
+Note, see below for the definition of \lt{}file-list\gt{}.
+The Include resource may also contain one or more Options resources that
+specify options such as compression to be applied to all or any subset of
+the files found when processing the file-list for backup. Please see
+below for more details concerning Options resources.
+
+There can be any number of {\bf Include} resources within the FileSet, each
+having its own list of directories or files to be backed up and the backup
+options defined by one or more Options resources. The {\bf file-list}
+consists of one file or directory name per line. Directory names should be
+specified without a trailing slash with Unix path notation.
+
+Windows users, please take note to specify directories (even c:/...) in
+Unix path notation. If you use Windows conventions, you will most likely
+not be able to restore your files due to the fact that the Windows
+path separator was defined as an escape character long before Windows
+existed, and Bacula adheres to that convention (i.e. \\ means the next character
+appears as itself).
+
+You should always specify a full path for every directory and file that you
+list in the FileSet. In addition, on Windows machines, you should {\bf
+always} prefix the directory or filename with the drive specification
+(e.g. {\bf c:/xxx}) using Unix directory name separators
+(forward slash). The drive letter itself can be upper or lower case (e.g.
+c:/xxx or C:/xxx).
+
+Bacula's default for processing directories is to recursively descend in
+the directory saving all files and subdirectories. Bacula will not by
+default cross filesystems (or mount points in Unix parlance). This means
+that if you specify the root partition (e.g. {\bf /}), Bacula will save
+only the root partition and not any of the other mounted filesystems.
+Similarly on Windows systems, you must explicitly specify each of the
+drives you want saved (e.g.
+{\bf c:/} and {\bf d:/} ...). In addition, at least for Windows systems, you
+will most likely want to enclose each specification within double quotes
+particularly if the directory (or file) name contains spaces. The {\bf df}
+command on Unix systems will show you which mount points you must specify to
+save everything. See below for an example.
+
+Take special care not to include a directory twice or Bacula will backup
+the same files two times wasting a lot of space on your archive device.
+Including a directory twice is very easy to do. For example:
+
+\footnotesize
+\begin{verbatim}
+ Include {
+ File = /
+ File = /usr
+ Options { compression=GZIP }
+ }
+\end{verbatim}
+\normalsize
+
+on a Unix system where /usr is a subdirectory (rather than a mounted
+filesystem) will cause /usr to be backed up twice. In this case, on Bacula
+versions prior to 1.32f-5-09Mar04 due to a bug, you will not be able to
+restore hard linked files that were backed up twice.
+
+If you have used Bacula prior to version 1.36.3, you will note three things in
+the new FileSet syntax:
+
+\begin{enumerate}
+\item There is no equal sign (=) after the Include and before the opening
+ brace (\{). The same is true for the Exclude.
+\item Each directory (or filename) to be included or excluded is preceded by a {\bf File
+ =}. Previously they were simply listed on separate lines.
+\item The options that previously appeared on the Include line now must be
+ specified within their own Options resource.
+\item The Exclude resource does not accept Options.
+\item When using wild-cards or regular expressions, directory names are
+ always terminated with a slash (/) and filenames have no trailing slash.
+\end{enumerate}
+
+The Options resource is optional, but when specified, it will contain a
+list of {\bf keyword=value} options to be applied to the file-list.
+See below for the definition of file-list.
+Multiple Options resources may be specified one after another. As the
+files are found in the specified directories, the Options will applied to
+the filenames to determine if and how the file should be backed up. The
+wildcard and regular expression pattern matching parts of the
+Options resources are checked in the order they are specified in the
+FileSet until the first one that matches. Once one matches, the
+compression and other flags within the Options specification will
+apply to the pattern matched.
+
+A key point is that in the absence of an Option or no other Option is
+matched, every file is accepted for backing up. This means that if
+you want to exclude something, you must explicitly specify an Option
+with an {\bf exclude = yes} and some pattern matching.
+
+Once Bacula determines that the Options resource matches the file under
+consideration, that file will be saved without looking at any other Options
+resources that may be present. This means that any wild cards must appear
+before an Options resource without wild cards.
+
+If for some reason, Bacula checks all the Options resources to a file under
+consideration for backup, but there are no matches (generally because of wild
+cards that don't match), Bacula as a default will then backup the file. This
+is quite logical if you consider the case of no Options clause is specified,
+where you want everything to be backed up, and it is important to keep in mind
+when excluding as mentioned above.
+
+However, one additional point is that in the case that no match was found,
+Bacula will use the options found in the last Options resource. As a
+consequence, if you want a particular set of "default" options, you should put
+them in an Options resource after any other Options.
+
+It is a good idea to put all your wild-card and regex expressions inside
+double quotes to prevent conf file scanning problems.
+
+This is perhaps a bit overwhelming, so there are a number of examples included
+below to illustrate how this works.
+
+You find yourself using a lot of Regex statements, which will cost quite a lot
+of CPU time, we recommend you simplify them if you can, or better yet
+convert them to Wild statements which are much more efficient.
+
+The directives within an Options resource may be one of the following:
+
+\begin{description}
+
+\item [compression=GZIP]
+\index[dir]{compression}
+\index[dir]{Directive!compression}
+ All files saved will be software compressed using the GNU ZIP
+ compression format. The compression is done on a file by file basis by
+ the File daemon. If there is a problem reading the tape in a single
+ record of a file, it will at most affect that file and none of the other
+ files on the tape. Normally this option is {\bf not} needed if you have
+ a modern tape drive as the drive will do its own compression. In fact,
+ if you specify software compression at the same time you have hardware
+ compression turned on, your files may actually take more space on the
+ volume.
+
+ Software compression is very important if you are writing your Volumes
+ to a file, and it can also be helpful if you have a fast computer but a
+ slow network, otherwise it is generally better to rely your tape drive's
+ hardware compression. As noted above, it is not generally a good idea
+ to do both software and hardware compression.
+
+ Specifying {\bf GZIP} uses the default compression level 6 (i.e. {\bf
+ GZIP} is identical to {\bf GZIP6}). If you want a different compression
+ level (1 through 9), you can specify it by appending the level number
+ with no intervening spaces to {\bf GZIP}. Thus {\bf compression=GZIP1}
+ would give minimum compression but the fastest algorithm, and {\bf
+ compression=GZIP9} would give the highest level of compression, but
+ requires more computation. According to the GZIP documentation,
+ compression levels greater than six generally give very little extra
+ compression and are rather CPU intensive.
+
+\item [signature=SHA1]
+\index[dir]{signature}
+\index[dir]{SHA1}
+\index[dir]{Directive!signature}
+ An SHA1 signature will be computed for all The SHA1 algorithm is
+ purported to be some what slower than the MD5 algorithm, but at the same
+ time is significantly better from a cryptographic point of view (i.e.
+ much fewer collisions, much lower probability of being hacked.) It adds
+ four more bytes than the MD5 signature. We strongly recommend that
+ either this option or MD5 be specified as a default for all files.
+ Note, only one of the two options MD5 or SHA1 can be computed for any
+ file.
+
+\item [signature=MD5]
+\index[dir]{signature}
+\index[dir]{MD5}
+\index[dir]{Directive!signature}
+ An MD5 signature will be computed for all files saved. Adding this
+ option generates about 5\% extra overhead for each file saved. In
+ addition to the additional CPU time, the MD5 signature adds 16 more
+ bytes per file to your catalog. We strongly recommend that this option
+ or the SHA1 option be specified as a default for all files.
+
+\item [verify=\lt{}options\gt{}]
+\index[dir]{verify}
+\index[dir]{Directive!verify}
+ The options letters specified are used when running a {\bf Verify
+ Level=Catalog} as well as the {\bf DiskToCatalog} level job. The options
+ letters may be any combination of the following:
+
+ \begin{description}
+
+ \item {\bf i}
+ compare the inodes
+
+ \item {\bf p}
+ compare the permission bits
+
+ \item {\bf n}
+ compare the number of links

+ \item {\bf s}
+ compare the size
+
+ \item {\bf a}
+ compare the access time
+
+ \item {\bf m}
+ compare the modification time (st\_mtime)
+
+ \item {\bf c}
+ compare the change time (st\_ctime)
+
+ \item {\bf d}
+ report file size decreases
+
+ \item {\bf 5}
+ compare the MD5 signature
+
+ \item {\bf 1}
+ compare the SHA1 signature
+ \end{description}
+
+ A useful set of general options on the {\bf Level=Catalog} or {\bf
+ Level=DiskToCatalog} verify is {\bf pins5} i.e. compare permission bits,
+ inodes, number of links, size, and MD5 changes.
+
+\item [onefs=yes|no]
+\index[dir]{onefs}
+\index[dir]{Directive!onefs}
+ If set to {\bf yes} (the default), {\bf Bacula} will remain on a single
+ file system. That is it will not backup file systems that are mounted
+ on a subdirectory. If you are using a *nix system, you may not even be
+ aware that there are several different filesystems as they are often
+ automatically mounted by the OS (e.g. /dev, /net, /sys, /proc, ...).
+ With Bacula 1.38.0 or later, it will inform you when it decides not to
+ traverse into another filesystem. This can be very useful if you forgot
+ to backup a particular partition. An example of the informational
+ message in the job report is:
+
+\footnotesize
+\begin{verbatim}
+rufus-fd: /misc is a different filesystem. Will not descend from / into /misc
+rufus-fd: /net is a different filesystem. Will not descend from / into /net
+rufus-fd: /var/lib/nfs/rpc_pipefs is a different filesystem. Will not descend from /var/lib/nfs into /var/lib/nfs/rpc_pipefs
+rufus-fd: /selinux is a different filesystem. Will not descend from / into /selinux
+rufus-fd: /sys is a different filesystem. Will not descend from / into /sys
+rufus-fd: /dev is a different filesystem. Will not descend from / into /dev
+rufus-fd: /home is a different filesystem. Will not descend from / into /home
+\end{verbatim}
+\normalsize
+
+ Note: in previous versions of Bacula, the above message was of the form:
+
+\footnotesize
+\begin{verbatim}
+Filesystem change prohibited. Will not descend into /misc
+\end{verbatim}
+\normalsize
+
+ If you wish to backup multiple filesystems, you can explicitly
+ list each filesystem you want saved. Otherwise, if you set the onefs option
+ to {\bf no}, Bacula will backup all mounted file systems (i.e. traverse mount
+ points) that are found within the {\bf FileSet}. Thus if you have NFS or
+ Samba file systems mounted on a directory listed in your FileSet, they will
+ also be backed up. Normally, it is preferable to set {\bf onefs=yes} and to
+ explicitly name each filesystem you want backed up. Explicitly naming the
+ filesystems you want backed up avoids the possibility of getting into a
+ infinite loop recursing filesystems. Another possibility is to
+ use {\bf onefs=no} and to set {\bf fstype=ext2, ...}.
+ See the example below for more details.
+
+ If you think that Bacula should be backing up a particular directory
+ and it is not, and you have {\bf onefs=no} set, before you complain,
+ please do:
+
+\footnotesize
+\begin{verbatim}
+ stat /
+ stat <filesystem>
+\end{verbatim}
+\normalsize
+
+where you replace {\bf filesystem} with the one in question. If the
+{\bf Device:} number is different for / and for your filesystem, then they
+are on different filesystems. E.g.
+\footnotesize
+\begin{verbatim}
+stat /
+ File: `/'
+ Size: 4096 Blocks: 16 IO Block: 4096 directory
+Device: 302h/770d Inode: 2 Links: 26
+Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root)
+Access: 2005-11-10 12:28:01.000000000 +0100
+Modify: 2005-09-27 17:52:32.000000000 +0200
+Change: 2005-09-27 17:52:32.000000000 +0200
+
+stat /net
+ File: `/home'
+ Size: 4096 Blocks: 16 IO Block: 4096 directory
+Device: 308h/776d Inode: 2 Links: 7
+Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root)
+Access: 2005-11-10 12:28:02.000000000 +0100
+Modify: 2005-11-06 12:36:48.000000000 +0100
+Change: 2005-11-06 12:36:48.000000000 +0100
+\end{verbatim}
+\normalsize
+
+ Also be aware that even if you include {\bf /home} in your list
+ of files to backup, as you most likely should, you will get the
+ informational message that "/home is a different filesystem" when
+ Bacula is processing the {\bf /} directory. This message does not
+ indicate an error. This message means that while examining the
+ {\bf File =} referred to in the second part of the message, Bacula will
+ not descend into the directory mentioned in the first part of the message.
+ However, it is possible that the separate filesystem will be backed up
+ despite the message. For example, consider the following FileSet:
+
+\footnotesize
+\begin{verbatim}
+ File = /
+ File = /var
+\end{verbatim}
+\normalsize
+
+ where {\bf /var} is a separate filesystem. In this example, you will get a
+ message saying that Bacula will not decend from {\bf /} into {\bf /var}. But
+ it is important to realise that Bacula will descend into {\bf /var} from the
+ second File directive shown above. In effect, the warning is bogus,
+ but it is supplied to alert you to possible omissions from your FileSet. In
+ this example, {\bf /var} will be backed up. If you changed the FileSet such
+ that it did not specify {\bf /var}, then {\bf /var} will not be backed up.
+
+
+\item [honor nodump flag=\lt{}yes|no\gt{}]
+\index[dir]{honornodumpflag}
+\index[dir]{Directive!honornodumpflag}
+ If your file system supports the {\bf nodump} flag (e. g. most
+ BSD-derived systems) Bacula will honor the setting of the flag
+ when this option is set to {\bf yes}. Files having this flag set
+ will not be included in the backup and will not show up in the
+ catalog. For directories with the {\bf nodump} flag set recursion
+ is turned off and the directory will be listed in the catalog.
+ If the {\bf honor nodump flag} option is not defined
+ or set to {\bf no} every file and directory will be eligible for
+ backup.
+
+
+\label{portable}
+\item [portable=yes|no]
+\index[dir]{portable}
+\index[dir]{Directive!portable}
+ If set to {\bf yes} (default is {\bf no}), the Bacula File daemon will
+ backup Win32 files in a portable format, but not all Win32 file
+ attributes will be saved and restored. By default, this option is set
+ to {\bf no}, which means that on Win32 systems, the data will be backed
+ up using Windows API calls and on WinNT/2K/XP, all the security and
+ ownership attributes will be properly backed up (and restored). However
+ this format is not portable to other systems -- e.g. Unix, Win95/98/Me.
+ When backing up Unix systems, this option is ignored, and unless you
+ have a specific need to have portable backups, we recommend accept the
+ default ({\bf no}) so that the maximum information concerning your files
+ is saved.
+
+\item [recurse=yes|no]
+\index[dir]{recurse}
+\index[dir]{Directive!recurse}
+ If set to {\bf yes} (the default), Bacula will recurse (or descend) into
+ all subdirectories found unless the directory is explicitly excluded
+ using an {\bf exclude} definition. If you set {\bf recurse=no}, Bacula
+ will save the subdirectory entries, but not descend into the
+ subdirectories, and thus will not save the files or directories
+ contained in the subdirectories. Normally, you will want the default
+ ({\bf yes}).
+
+\item [sparse=yes|no]
+\index[dir]{sparse}
+\index[dir]{Directive!sparse}
+ Enable special code that checks for sparse files such as created by
+ ndbm. The default is {\bf no}, so no checks are made for sparse files.
+ You may specify {\bf sparse=yes} even on files that are not sparse file.
+ No harm will be done, but there will be a small additional overhead to
+ check for buffers of all zero, and a small additional amount of space on
+ the output archive will be used to save the seek address of each
+ non-zero record read.
+
+ {\bf Restrictions:} Bacula reads files in 32K buffers. If the whole
+ buffer is zero, it will be treated as a sparse block and not written to
+ tape. However, if any part of the buffer is non-zero, the whole buffer
+ will be written to tape, possibly including some disk sectors (generally
+ 4098 bytes) that are all zero. As a consequence, Bacula's detection of
+ sparse blocks is in 32K increments rather than the system block size.
+ If anyone considers this to be a real problem, please send in a request
+ for change with the reason.
+
+ If you are not familiar with sparse files, an example is say a file
+ where you wrote 512 bytes at address zero, then 512 bytes at address 1
+ million. The operating system will allocate only two blocks, and the
+ empty space or hole will have nothing allocated. However, when you read
+ the sparse file and read the addresses where nothing was written, the OS
+ will return all zeros as if the space were allocated, and if you backup
+ such a file, a lot of space will be used to write zeros to the volume.
+ Worse yet, when you restore the file, all the previously empty space
+ will now be allocated using much more disk space. By turning on the
+ {\bf sparse} option, Bacula will specifically look for empty space in
+ the file, and any empty space will not be written to the Volume, nor
+ will it be restored. The price to pay for this is that Bacula must
+ search each block it reads before writing it. On a slow system, this
+ may be important. If you suspect you have sparse files, you should
+ benchmark the difference or set sparse for only those files that are
+ really sparse.
+
+\label{readfifo}
+\item [readfifo=yes|no]
+\index[dir]{readfifo}
+\index[dir]{Directive!readfifo}
+ If enabled, tells the Client to read the data on a backup and write the
+ data on a restore to any FIFO (pipe) that is explicitly mentioned in the
+ FileSet. In this case, you must have a program already running that
+ writes into the FIFO for a backup or reads from the FIFO on a restore.
+ This can be accomplished with the {\bf RunBeforeJob} directive. If this
+ is not the case, Bacula will hang indefinitely on reading/writing the
+ FIFO. When this is not enabled (default), the Client simply saves the
+ directory entry for the FIFO.
+
+ Unfortunately, when Bacula runs a RunBeforeJob, it waits until that
+ script terminates, and if the script accesses the FIFO to write
+ into the it, the Bacula job will block and everything will stall.
+ However, Vladimir Stavrinov as supplied tip that allows this feature
+ to work correctly. He simply adds the following to the beginning
+ of the RunBeforeJob script:
+
+\begin{verbatim}
+ exec > /dev/null
+\end{verbatim}
+
+\item [noatime=yes|no]
+\index[dir]{noatime}
+\index[dir]{Directive!noatime}
+ If enabled, and if your Operating System supports the O\_NOATIME file
+ open flag, Bacula will open all files to be backed up with this option.
+ It makes it possible to read a file without updating the inode atime
+ (and also without the inode ctime update which happens if you try to set
+ the atime back to its previous value). It also prevents a race
+ condition when two programs are reading the same file, but only one does
+ not want to change the atime. It's most useful for backup programs and
+ file integrity checkers (and bacula can fit on both categories).
+
+ This option is particularly useful for sites where users are sensitive
+ to their MailBox file access time. It replaces both the {\bf keepatime}
+ option without the inconveniences of that option (see below).
+
+ If your Operating System does not support this option, it will be
+ silently ignored by Bacula.
+
+
+\item [mtimeonly=yes|no]
+\index[dir]{mtimeonly}
+\index[dir]{Directive!mtimeonly}
+ If enabled, tells the Client that the selection of files during
+ Incremental and Differential backups should based only on the st\_mtime
+ value in the stat() packet. The default is {\bf no} which means that
+ the selection of files to be backed up will be based on both the
+ st\_mtime and the st\_ctime values. In general, it is not recommended
+ to use this option.
+
+\item [keepatime=yes|no]
+\index[dir]{keepatime}
+\index[dir]{Directive!keepatime}
+ The default is {\bf no}. When enabled, Bacula will reset the st\_atime
+ (access time) field of files that it backs up to their value prior to
+ the backup. This option is not generally recommended as there are very
+ few programs that use st\_atime, and the backup overhead is increased
+ because of the additional system call necessary to reset the times.
+ However, for some files, such as mailboxes, when Bacula backs up the
+ file, the user will notice that someone (Bacula) has accessed the
+ file. In this, case keepatime can be useful.
+ (I'm not sure this works on Win32).
+
+ Note, if you use this feature, when Bacula resets the access time, the
+ change time (st\_ctime) will automatically be modified by the system,
+ so on the next incremental job, the file will be backed up even if
+ it has not changed. As a consequence, you will probably also want
+ to use {\bf mtimeonly = yes} as well as keepatime (thanks to
+ Rudolf Cejka for this tip).
+
+\item [checkfilechanges=yes|no]
+\index[dir]{checkfilechanges}
+\index[dir]{Directive!checkfilechanges}
+ On versions 2.0.4 or greater,
+ if enabled, the Client will checks size, age of each file after
+ their backup to see if they have changed during backup. If time
+ or size mismatch, an error will raise.
+
+\begin{verbatim}
+ zog-fd: Client1.2007-03-31_09.46.21 Error: /tmp/test mtime changed during backup.
+\end{verbatim}
+
+ In general, it is recommended to use this option.
+
+\item [hardlinks=yes|no]
+\index[dir]{hardlinks}
+\index[dir]{Directive!hardlinks}
+ When enabled (default), this directive will cause hard links to be
+ backed up. However, the File daemon keeps track of hard linked files and
+ will backup the data only once. The process of keeping track of the
+ hard links can be quite expensive if you have lots of them (tens of
+ thousands or more). This doesn't occur on normal Unix systems, but if
+ you use a program like BackupPC, it can create hundreds of thousands, or
+ even millions of hard links. Backups become very long and the File daemon
+ will consume a lot of CPU power checking hard links. In such a case,
+ set {\bf hardlinks=no} and hard links will not be backed up. Note, using
+ this option will most likely backup more data and on a restore the file
+ system will not be restored identically to the original.
+
+\item [wild=\lt{}string\gt{}]
+\index[dir]{wild}
+\index[dir]{Directive!wild}
+ Specifies a wild-card string to be applied to the filenames and
+ directory names. Note, if {\bf Exclude} is not enabled, the wild-card
+ will select which files are to be included. If {\bf Exclude=yes} is
+ specified, the wild-card will select which files are to be excluded.
+ Multiple wild-card directives may be specified, and they will be applied
+ in turn until the first one that matches. Note, if you exclude a
+ directory, no files or directories below it will be matched.
+
+ You may want to test your expressions prior to running your
+ backup by using the bwild program. Please see the
+ \ilink{Utilities}{bwild} chapter of this manual for
+ more. You can also test your full FileSet definition by using
+ the \ilink{estimate}{estimate} command in the Console
+ chapter of this manual.
+ It is recommended to enclose the string in double quotes.
+
+\item [wilddir=\lt{}string\gt{}]
+\index[dir]{wilddir}
+\index[dir]{Directive!wilddir}
+ Specifies a wild-card string to be applied to directory names only. No
+ filenames will be matched by this directive. Note, if {\bf Exclude} is
+ not enabled, the wild-card will select directories to be
+ included. If {\bf Exclude=yes} is specified, the wild-card will select
+ which directories are to be excluded. Multiple wild-card directives may be

+ However, note that the match is done against the full path and filename,
+ so your wild-card string must take into account that filenames
+ are preceded by the full path.
+ If {\bf Exclude}
+ is not enabled, the wild-card will select which files are to be
+ included. If {\bf Exclude=yes} is specified, the wild-card will select

+
+\item [regex=\lt{}string\gt{}]
+\index[dir]{regex}
+\index[dir]{Directive!regex}
+ Specifies a POSIX extended regular expression to be applied to the
+ filenames and directory names, which include the full path. If {\bf
+ Exclude} is not enabled, the regex will select which files are to be
+ included. If {\bf Exclude=yes} is specified, the regex will select
+ which files are to be excluded. Multiple regex directives may be
+ specified within an Options resource, and they will be applied in turn
+ until the first one that matches. Note, if you exclude a directory, no
+ files or directories below it will be matched.
+
+ It is recommended to enclose the string in double quotes.
+
+ The regex libraries differ from one operating system to
+ another, and in addition, regular expressions are complicated,
+ so you may want to test your expressions prior to running your
+ backup by using the bregex program. Please see the
+ \ilink{Utilities}{bwild} chapter of this manual for
+ more. You can also test your full FileSet definition by using
+ the \ilink{estimate}{estimate} command in the Console
+ chapter of this manual.
+
+ You find yourself using a lot of Regex statements, which will cost quite a lot
+ of CPU time, we recommend you simplify them if you can, or better yet
+ convert them to Wild statements which are much more efficient.
+
+
+\item [regexfile=\lt{}string\gt{}]
+\index[dir]{regexfile}
+\index[dir]{Directive!regexfile}
+ Specifies a POSIX extended regular expression to be applied to
+ non-directories. No directories will be matched by this directive.
+ However, note that the match is done against the full path and
+ filename, so your regex string must take into account that filenames
+ are preceded by the full path.

+ Specifies a POSIX extended regular expression to be applied to directory
+ names only. No filenames will be matched by this directive. Note, if
+ {\bf Exclude} is not enabled, the regex will select directories
+ files are to be included. If {\bf Exclude=yes} is specified, the

+
+
+\item [exclude=yes|no]
+\index[dir]{exclude}
+\index[dir]{Directive!exclude}
+ The default is {\bf no}. When enabled, any files matched within the
+ Options will be excluded from the backup.
+
+\label{ACLSupport}
+\item [aclsupport=yes|no]
+\index[dir]{aclsupport}
+\index[dir]{Directive!aclsupport}
+ The default is {\bf no}. If this option is set to yes, and you have the
+ POSIX {\bf libacl} installed on your system, Bacula will backup the file
+ and directory UNIX Access Control Lists (ACL) as defined in IEEE Std
+ 1003.1e draft 17 and "POSIX.1e" (abandoned). This feature is
+ available on UNIX only and depends on the ACL library. Bacula is
+ automatically compiled with ACL support if the {\bf libacl} library is
+ installed on your system (shown in config.out). While restoring the
+ files Bacula will try to restore the ACLs, if there is no ACL support
+ available on the system, Bacula restores the files and directories but
+ not the ACL information. Please note, if you backup an EXT3 or XFS
+ filesystem with ACLs, then you restore them to a different filesystem
+ (perhaps reiserfs) that does not have ACLs, the ACLs will be ignored.
+
+\item [ignore case=yes|no]
+\index[dir]{ignore case}
+\index[dir]{Directive!ignore case}
+ The default is {\bf no}. On Windows systems, you will almost surely
+ want to set this to {\bf yes}. When this directive is set to {\bf yes}
+ all the case of character will be ignored in wild-card and regex
+ comparisons. That is an uppercase A will match a lowercase a.
+
+\item [fstype=filesystem-type]
+\index[dir]{fstype}
+\index[dir]{Directive!fstype}
+ This option allows you to select files and directories by the
+ filesystem type. The permitted filesystem-type names are:
+
+ ext2, jfs, ntfs, proc, reiserfs, xfs, usbdevfs, sysfs, smbfs,
+ iso9660. For ext3 systems, use ext2.
+
+ You may have multiple Fstype directives, and thus permit matching
+ of multiple filesystem types within a single Options resource. If
+ the type specified on the fstype directive does not match the
+ filesystem for a particular directive, that directory will not be
+ backed up. This directive can be used to prevent backing up
+ non-local filesystems. Normally, when you use this directive, you
+ would also set {\bf onefs=no} so that Bacula will traverse filesystems.
+
+ This option is not implemented in Win32 systems.
+
+\item [DriveType=Windows-drive-type]
+\index[dir]{DriveType}
+\index[dir]{Directive!DriveType}
+ This option is effective only on Windows machines and is
+ somewhat similar to the Unix/Linux {\bf fstype} described
+ above, except that it allows you to select what Windows
+ drive types you want to allow. By default all drive
+ types are accepted.
+
+ The permitted drivetype names are:
+
+ removable, fixed, remote, cdrom, ramdisk
+
+ You may have multiple Driveype directives, and thus permit matching
+ of multiple drive types within a single Options resource. If
+ the type specified on the drivetype directive does not match the
+ filesystem for a particular directive, that directory will not be
+ backed up. This directive can be used to prevent backing up
+ non-local filesystems. Normally, when you use this directive, you
+ would also set {\bf onefs=no} so that Bacula will traverse filesystems.
+
+ This option is not implemented in Unix/Linux systems.
+
+
+\item [hfsplussupport=yes|no]
+\index[dir]{hfsplussupport}
+\index[dir]{Directive!hfsplussupport}
+ This option allows you to turn on support for Mac OSX HFS plus
+ finder information.
+
+\item [strippath=\lt{}integer\gt{}]
+\index[dir]{strippath}
+\index[dir]{Directive!strippath}
+ This option will cause {\bf integer} paths to be stripped from
+ the front of the full path/filename being backed up. This can
+ be useful if you are migrating data from another vendor or if
+ you have taken a snapshot into some subdirectory. This directive
+ can cause your filenames to be overlayed with regular backup data,
+ so should be used only by experts and with great care.
+\end{description}
+
+{\bf \lt{}file-list\gt{}} is a list of directory and/or filename names
+specified with a {\bf File =} directive. To include names containing spaces,
+enclose the name between double-quotes. Wild-cards are not interpreted
+in file-lists. They can only be specified in Options resources.
+
+There are a number of special cases when specifying directories and files in a
+{\bf file-list}. They are:
+
+\begin{itemize}
+\item Any name preceded by an at-sign (@) is assumed to be the name of a
+ file, which contains a list of files each preceded by a "File =". The
+ named file is read once when the configuration file is parsed during the
+ Director startup. Note, that the file is read on the Director's machine
+ and not on the Client's. In fact, the @filename can appear anywhere
+ within the conf file where a token would be read, and the contents of
+ the named file will be logically inserted in the place of the @filename.
+ What must be in the file depends on the location the @filename is
+ specified in the conf file. For example:
+
+\footnotesize
+\begin{verbatim}
+Include {
+ Options { compression=GZIP }
+ @/home/files/my-files
+}
+\end{verbatim}
+\normalsize
+
+\item Any name beginning with a vertical bar (|) is assumed to be the name of
+ a program. This program will be executed on the Director's machine at
+ the time the Job starts (not when the Director reads the configuration
+ file), and any output from that program will be assumed to be a list of
+ files or directories, one per line, to be included. Before submitting the
+ specified command bacula will performe
+ \ilink{character substitution}{character substitution}.
+
+ This allows you to have a job that, for example, includes all the local
+ partitions even if you change the partitioning by adding a disk. The
+ examples below show you how to do this. However, please note two
+ things: \\
+ 1. if you want the local filesystems, you probably should be
+ using the new {\bf fstype} directive, which was added in version 1.36.3
+ and set {\bf onefs=no}.
+ \\
+
+ 2. the exact syntax of the command needed in the examples below is very
+ system dependent. For example, on recent Linux systems, you may need to
+ add the -P option, on FreeBSD systems, the options will be different as
+ well.
+
+ In general, you will need to prefix your command or commands with a {\bf
+ sh -c} so that they are invoked by a shell. This will not be the case
+ if you are invoking a script as in the second example below. Also, you
+ must take care to escape (precede with a \textbackslash{}) wild-cards,
+ shell character, and to ensure that any spaces in your command are
+ escaped as well. If you use a single quotes (') within a double quote
+ ("), Bacula will treat everything between the single quotes as one field
+ so it will not be necessary to escape the spaces. In general, getting
+ all the quotes and escapes correct is a real pain as you can see by the
+ next example. As a consequence, it is often easier to put everything in
+ a file and simply use the file name within Bacula. In that case the
+ {\bf sh -c} will not be necessary providing the first line of the file
+ is {\bf \#!/bin/sh}.
+
+ As an example:
+
+\footnotesize
+\begin{verbatim}
+
+Include {
+ Options { signature = SHA1 }
+ File = "|sh -c 'df -l | grep \"^/dev/hd[ab]\" | grep -v \".*/tmp\" \
+ | awk \"{print \\$6}\"'"
+}
+\end{verbatim}
+\normalsize
+
+ will produce a list of all the local partitions on a Red Hat Linux system.
+ Note, the above line was split, but should normally be written on one line.
+ Quoting is a real problem because you must quote for Bacula which consists of
+ preceding every \textbackslash{} and every " with a \textbackslash{}, and
+ you must also quote for the shell command. In the end, it is probably easier
+ just to execute a small file with:
+
+
+\footnotesize
+\begin{verbatim}
+Include {
+ Options {
+ signature=MD5
+ }
+ File = "|my_partitions"
+}
+\end{verbatim}
+\normalsize
+
+ where my\_partitions has:
+
+\footnotesize
+\begin{verbatim}
+#!/bin/sh
+df -l | grep "^/dev/hd[ab]" | grep -v ".*/tmp" \
+ | awk "{print \$6}"
+\end{verbatim}
+\normalsize
+
+ If the vertical bar (|) in front of my\_partitions is preceded by a
+ backslash as in \textbackslash{}|, the program will be executed on the
+ Client's machine instead of on the Director's machine.
+ Please note that if the filename is given within quotes, you
+ will need to use two slashes. An example, provided by John Donagher,
+ that backs up all the local UFS partitions on a remote system is:
+
+\footnotesize
+\begin{verbatim}
+FileSet {
+ Name = "All local partitions"
+ Include {
+ Options { signature=SHA1; onefs=yes; }
+ File = "\\|bash -c \"df -klF ufs | tail +2 | awk '{print \$6}'\""
+ }
+}
+\end{verbatim}
+\normalsize
+
+ The above requires two backslash characters after the double quote (one
+ preserves the next one). If you are a Linux user, just change the {\bf ufs}
+ to {\bf ext3} (or your preferred filesystem type), and you will be in
+ business.
+
+ If you know what filesystems you have mounted on your system, e.g.
+ for Red Hat Linux normally only ext2 and ext3, you can backup
+ all local filesystems using something like:
+
+\footnotesize
+\begin{verbatim}
+
+Include {
+ Options { signature = SHA1; onfs=no; fstype=ext2 }
+ File = /
+}
+\end{verbatim}
+\normalsize
+
+
+\item Any file-list item preceded by a less-than sign (\lt{}) will be taken
+ to be a file. This file will be read on the Director's machine (see
+ below for doing it on the Client machine) at the time
+ the Job starts, and the data will be assumed to be a list of directories or
+ files, one per line, to be included. The names should start in column 1 and
+ should not be quoted even if they contain spaces. This feature allows you to
+ modify the external file and change what will be saved without stopping and
+ restarting Bacula as would be necessary if using the @ modifier noted above.
+ For example:
+
+\footnotesize
+\begin{verbatim}
+Include {
+ Options { signature = SHA1 }
+ File = "</home/files/local-filelist"
+}
+\end{verbatim}
+\normalsize
+
+ If you precede the less-than sign (\lt{}) with a backslash as in
+ \textbackslash{}\lt{}, the file-list will be read on the Client machine
+ instead of on the Director's machine. Please note that if the filename
+ is given within quotes, you will need to use two slashes.
+
+\footnotesize
+\begin{verbatim}
+Include {
+ Options { signature = SHA1 }
+ File = "\\</home/xxx/filelist-on-client"
+}
+\end{verbatim}
+\normalsize
+
+\item If you explicitly specify a block device such as {\bf /dev/hda1}, then
+ Bacula (starting with version 1.28) will assume that this is a raw partition
+ to be backed up. In this case, you are strongly urged to specify a {\bf
+ sparse=yes} include option, otherwise, you will save the whole partition
+ rather than just the actual data that the partition contains. For example:
+
+\footnotesize
+\begin{verbatim}
+Include {
+ Options { signature=MD5; sparse=yes }
+ File = /dev/hd6
+}
+\end{verbatim}
+\normalsize
+
+ will backup the data in device /dev/hd6. Note, the {bf /dev/hd6} must be
+ the raw partition itself. Bacula will not back it up as a raw device if
+ you specify a symbolic link to a raw device such as my be created by the
+ LVM Snapshot utilities.
+
+ Ludovic Strappazon has pointed out that this feature can be used to backup a
+ full Microsoft Windows disk. Simply boot into the system using a Linux Rescue
+ disk, then load a statically linked Bacula as described in the
+ \ilink{ Disaster Recovery Using Bacula}{RescueChapter} chapter of
+ this manual. Then save the whole disk partition. In the case of a disaster,
+ you can then restore the desired partition by again booting with the rescue
+ disk and doing a restore of the partition.
+ \item If you explicitly specify a FIFO device name (created with mkfifo), and
+ you add the option {\bf readfifo=yes} as an option, Bacula will read the FIFO
+ and back its data up to the Volume. For example:
+
+\footnotesize
+\begin{verbatim}
+Include {
+ Options {
+ signature=SHA1
+ readfifo=yes
+ }
+ File = /home/abc/fifo
+}
+\end{verbatim}
+\normalsize
+
+ if {\bf /home/abc/fifo} is a fifo device, Bacula will open the fifo,
+ read it, and store all data thus obtained on the Volume. Please note,
+ you must have a process on the system that is writing into the fifo, or
+ Bacula will hang, and after one minute of waiting, Bacula will give up
+ and go on to the next file. The data read can be anything since Bacula
+ treats it as a stream.
+
+ This feature can be an excellent way to do a "hot" backup of a very
+ large database. You can use the {\bf RunBeforeJob} to create the fifo
+ and to start a program that dynamically reads your database and writes
+ it to the fifo. Bacula will then write it to the Volume. Be sure to
+ read the \ilink{readfifo section}{readfifo} that gives a
+ tip to ensure that the RunBeforeJob does not block Bacula.
+
+ During the restore operation, the inverse is true, after Bacula creates
+ the fifo if there was any data stored with it (no need to explicitly
+ list it or add any options), that data will be written back to the fifo.
+ As a consequence, if any such FIFOs exist in the fileset to be restored,
+ you must ensure that there is a reader program or Bacula will block, and
+ after one minute, Bacula will time out the write to the fifo and move on
+ to the next file.
+
+\item A file-list may not contain wild-cards. Use directives in the
+ Options resource if you wish to specify wild-cards or regular expression
+ matching.
+\end{itemize}
+
+\section{FileSet Examples}
+\index[general]{Examples!FileSet }
+\index[general]{FileSet Examples}
+
+The following is an example of a valid FileSet resource definition. Note,
+the first Include pulls in the contents of the file {\bf /etc/backup.list}
+when Bacula is started (i.e. the @), and that file must have each filename
+to be backed up preceded by a {\bf File =} and on a separate line.
+
+\footnotesize
+\begin{verbatim}
+FileSet {
+ Name = "Full Set"
+ Include {
+ Options {
+ Compression=GZIP
+ signature=SHA1
+ Sparse = yes
+ }
+ @/etc/backup.list
+ }
+ Include {
+ Options {
+ wildfile = "*.o"
+ wildfile = "*.exe"
+ Exclude = yes
+ }
+ File = /root/myfile
+ File = /usr/lib/another_file
+ }
+}
+\end{verbatim}
+\normalsize
+
+In the above example, all the files contained in /etc/backup.list will
+be compressed with GZIP compression, an SHA1 signature will be computed on the
+file's contents (its data), and sparse file handling will apply.
+
+The two directories /root/myfile and /usr/lib/another\_file will also be saved
+without any options, but all files in those directories with the extensions
+{\bf .o} and {\bf .exe} will be excluded.
+
+Let's say that you now want to exclude the directory /tmp. The simplest way
+to do so is to add an exclude directive that lists /tmp. The example
+above would then become:
+
+\footnotesize
+\begin{verbatim}
+FileSet {
+ Name = "Full Set"
+ Include {
+ Options {
+ Compression=GZIP
+ signature=SHA1
+ Sparse = yes
+ }
+ @/etc/backup.list
+ }
+ Include {
+ Options {
+ wildfile = "*.o"
+ wildfile = "*.exe"
+ Exclude = yes
+ }
+ File = /root/myfile
+ File = /usr/lib/another_file
+ }
+ Exclude {
+ File = /tmp
+ }
+}
+\end{verbatim}
+\normalsize
+
+
+You can add wild-cards to the File directives listed in the Exclude
+directory, but you need to take care because if you exclude a directory,
+it and all files and directories below it will also be excluded.
+
+Now lets take a slight variation on the above and suppose
+you want to save all your whole filesystem except {\bf /tmp}.
+The problem that comes up is that Bacula will not normally
+cross from one filesystem to another.
+Doing a {\bf df} command, you get the following output:
+
+\footnotesize
+\begin{verbatim}
+[kern@rufus k]$ df
+Filesystem 1k-blocks Used Available Use% Mounted on
+/dev/hda5 5044156 439232 4348692 10% /
+/dev/hda1 62193 4935 54047 9% /boot

+deuter:/files 44133352 27652876 14238608 67% /mnt/deuter/files
+\end{verbatim}
+\normalsize
+
+And we see that there are a number of separate filesystems (/ /boot
+/home /rescue /tmp and /usr not to mention mounted systems).
+If you specify only {\bf /} in your Include list, Bacula will only save the
+Filesystem {\bf /dev/hda5}. To save all filesystems except {\bf /tmp} with
+out including any of the Samba or NFS mounted systems, and explicitly
+excluding a /tmp, /proc, .journal, and .autofsck, which you will not want to
+be saved and restored, you can use the following:
+
+\footnotesize
+\begin{verbatim}
+FileSet {
+ Name = Include_example
+ Include {
+ Options {
+ wilddir = /proc
+ wilddir = /tmp
+ wildfile = "/.journal"
+ wildfile = "/.autofsck"
+ exclude = yes
+ }
+ File = /
+ File = /boot
+ File = /home
+ File = /rescue
+ File = /usr
+ }
+}
+\end{verbatim}
+\normalsize
+
+Since /tmp is on its own filesystem and it was not explicitly named in the
+Include list, it is not really needed in the exclude list. It is better to
+list it in the Exclude list for clarity, and in case the disks are changed so
+that it is no longer in its own partition.
+
+Now, lets assume you only want to backup .Z and .gz files and nothing
+else. This is a bit trickier because Bacula by default will select
+everything to backup, so we must exclude everything but .Z and .gz files.
+If we take the first example above and make the obvious modifications
+to it, we might come up with a FileSet that looks like this:
+
+\footnotesize
+\begin{verbatim}
+FileSet {
+ Name = "Full Set"
+ Include { !!!!!!!!!!!!
+ Options { This
+ wildfile = "*.Z" example
+ wildfile = "*.gz" doesn't
+ work
+ } !!!!!!!!!!!!
+ File = /myfile
+ }
+}
+\end{verbatim}
+\normalsize
+
+The *.Z and *.gz files will indeed be backed up, but all other files
+that are not matched by the Options directives will automatically
+be backed up too (i.e. that is the default rule).
+
+To accomplish what we want, we must explicitly exclude all other files.
+We do this with the following:
+
+\footnotesize
+\begin{verbatim}
+FileSet {
+ Name = "Full Set"
+ Include {
+ Options {
+ wildfile = "*.Z"
+ wildfile = "*.gz"
+ }
+ Options {
+ Exclude = yes
+ RegexFile = ".*"
+ }
+ File = /myfile
+ }
+}
+\end{verbatim}
+\normalsize
+
+The "trick" here was to add a RegexFile expression that matches
+all files. It does not match directory names, so all directories in
+/myfile will be backed up (the directory entry) and any *.Z and *.gz
+files contained in them. If you know that certain directories do
+not contain any *.Z or *.gz files and you do not want the directory
+entries backed up, you will need to explicitly exclude those directories.
+Backing up a directory entries is not very expensive.
+
+Bacula uses the system regex library and some of them are
+different on different OSes. The above has been reported not to work
+on FreeBSD. This can be tested by using the {\bf estimate job=job-name
+listing} command in the console and adapting the RegexFile expression
+appropriately. In a future version of Bacula, we will supply our own
+Regex code to avoid such system dependencies.
+
+Please be aware that allowing Bacula to traverse or change file systems can be
+{\bf very} dangerous. For example, with the following:
+
+\footnotesize
+\begin{verbatim}
+FileSet {
+ Name = "Bad example"
+ Include {
+ Options { onefs=no }
+ File = /mnt/matou
+ }
+}
+\end{verbatim}
+\normalsize
+
+you will be backing up an NFS mounted partition ({\bf /mnt/matou}), and since
+{\bf onefs} is set to {\bf no}, Bacula will traverse file systems. Now if {\bf
+/mnt/matou} has the current machine's file systems mounted, as is often the
+case, you will get yourself into a recursive loop and the backup will never
+end.
+
+As a final example, let's say that you have only one or two
+subdirectories of /home that you want to backup. For example,
+you want to backup only subdirectories beginning with the letter
+a and the letter b -- i.e. /home/a* and /home/b*. Now, you might first
+try:
+\footnotesize
+\begin{verbatim}
+FileSet {
+ Name = "Full Set"
+ Include {
+ Options {
+ wilddir = "/home/a*"
+ wilddir = "/home/b*"
+ }
+ File = /home
+ }
+}
+\end{verbatim}
+\normalsize
+
+The problem is that the above will include everything in /home. To get
+things to work correctly, you need to start with the idea of exclusion
+instead of inclusion. So, you could simply exclude all directories
+except the two you want to use:
+\footnotesize
+\begin{verbatim}
+FileSet {
+ Name = "Full Set"
+ Include {
+ Options {
+ RegexDir = "^/home/[c-z]"
+ exclude = yes
+ }
+ File = /home
+ }
+}
+\end{verbatim}
+\normalsize
+
+And assuming that all subdirectories start with a lowercase letter, this
+would work.
+
+An alternative would be to include the two subdirectories desired and
+exclude everything else:
+\footnotesize
+\begin{verbatim}
+FileSet {
+ Name = "Full Set"
+ Include {
+ Options {
+ wilddir = "/home/a*"
+ wilddir = "/home/b*"
+ }
+ Options {
+ RegexDir = ".*"
+ exclude = yes
+ }
+ File = /home
+ }
+}
+\end{verbatim}
+\normalsize
+
+\section{Backing up Raw Partitions}
+\index[general]{Backing up!Partitions }
+\index[general]{Backing up Raw Partitions }
+
+The following FileSet definition will backup a raw partition:
+
+\footnotesize
+\begin{verbatim}
+FileSet {
+ Name = "RawPartition"
+ Include {
+ Options { sparse=yes }
+ File = /dev/hda2
+ }
+}
+\end{verbatim}
+\normalsize
+
+While backing up and restoring a raw partition, you should ensure that no
+other process including the system is writing to that partition. As a
+precaution, you are strongly urged to ensure that the raw partition is not
+mounted or is mounted read-only. If necessary, this can be done using the {\bf
+RunBeforeJob} directive.
+
+
+\section{Excluding Files and Directories}
+\index[general]{Directories!Excluding Files and }
+\index[general]{Excluding Files and Directories }
+
+You may also include full filenames or directory names in addition to using
+wild-cards and {\bf Exclude=yes} in the Options resource as specified above by
+simply including the files to be excluded in an Exclude resource within the
+FileSet. For example:
+
+\footnotesize
+\begin{verbatim}
+FileSet {
+ Name = Exclusion_example
+ Include {
+ Options {
+ Signature = SHA1
+ }
+ File = /
+ File = /boot
+ File = /home
+ File = /rescue
+ File = /usr
+ }
+ Exclude {
+ File = /proc
+ File = /tmp
+ File = .journal
+ File = .autofsck
+ }
+}
+\end{verbatim}
+\normalsize
+
+\label{win32}
+\section{Windows FileSets}
+\index[general]{Windows FileSets }
+\index[general]{FileSets!Windows }
+If you are entering Windows file names, the directory path may be preceded by
+the drive and a colon (as in c:). However, the path separators must be
+specified in Unix convention (i.e. forward slash (/)). If you wish to include
+a quote in a file name, precede the quote with a backslash
+(\textbackslash{}). For example you might use the following
+for a Windows machine to backup the "My Documents" directory:
+
+\footnotesize
+\begin{verbatim}
+FileSet {
+ Name = "Windows Set"
+ Include {
+ Options {
+ WildFile = "*.obj"
+ WildFile = "*.exe"
+ exclude = yes
+ }
+ File = "c:/My Documents"
+ }
+}
+\end{verbatim}
+\normalsize
+
+For exclude lists to work correctly on Windows, you must observe the following
+rules:
+
+\begin{itemize}
+\item Filenames are case sensitive, so you must use the correct case.
+\item To exclude a directory, you must not have a trailing slash on the
+ directory name.
+\item If you have spaces in your filename, you must enclose the entire name
+ in double-quote characters ("). Trying to use a backslash before the space
+ will not work.
+\item If you are using the old Exclude syntax (noted below), you may not
+ specify a drive letter in the exclude. The new syntax noted above
+ should work fine including driver letters.
+\end{itemize}
+
+Thanks to Thiago Lima for summarizing the above items for us. If you are
+having difficulties getting includes or excludes to work, you might want to
+try using the {\bf estimate job=xxx listing} command documented in the
+\ilink{Console chapter}{estimate} of this manual.
+
+On Win32 systems, if you move a directory or file or rename a file into the
+set of files being backed up, and a Full backup has already been made, Bacula
+will not know there are new files to be saved during an Incremental or
+Differential backup (blame Microsoft, not me). To avoid this problem, please
+{\bf copy} any new directory or files into the backup area. If you do not have
+enough disk to copy the directory or files, move them, but then initiate a
+Full backup.

+\index[general]{Testing Your FileSet }
+
+If you wish to get an idea of what your FileSet will really backup or if your
+exclusion rules will work correctly, you can test it by using the {\bf
+estimate} command in the Console program. See the
+\ilink{estimate}{estimate} in the Console chapter of this
+manual.
+
+As an example, suppose you add the following test FileSet:
+
+\footnotesize
+\begin{verbatim}
+FileSet {
+ Name = Test
+ Include {
+ File = /home/xxx/test
+ Options {
+ regex = ".*\.c$"
+ }
+ }
+}
+\end{verbatim}
+\normalsize
+
+You could then add some test files to the directory {\bf /home/xxx/test}
+and use the following command in the console:
+
+\footnotesize
+\begin{verbatim}
+estimate job=<any-job-name> listing client=<desired-client> fileset=Test
+\end{verbatim}
+\normalsize
+
+to give you a listing of all files that match.

+
+# Version Information:
+# 16-Feb-2005 -- Original Creation. Karl E. Cunningham
+# 14-Mar-2005 -- Clarified and Consolodated some of the code.
+# Changed to smoothly handle single and multiple indices.
+
+# Two LaTeX index formats are supported...
+# --- SINGLE INDEX ---
+# \usepackage{makeidx}
+# \makeindex
+# \index{entry1}
+# \index{entry2}
+# \index{entry3}
+# ...
+# \printindex
+#
+# --- MULTIPLE INDICES ---
+#
+# \usepackage{makeidx}
+# \usepackage{index}
+# \makeindex -- latex2html doesn't care but LaTeX does.
+# \newindex{ref1}{ext1}{ext2}{title1}
+# \newindex{ref2}{ext1}{ext2}{title2}
+# \newindex{ref3}{ext1}{ext2}{title3}

+# ___________________
+#
+# For the multiple-index style, each index is identified by the ref argument to \newindex, \index,
+# and \printindex. A default index is allowed, which is indicated by omitting the optional
+# argument. The default index does not require a \newindex command. As \index commands
+# are encountered, their entries are stored according
+# to the ref argument. When the \printindex command is encountered, the stored index
+# entries for that argument are retrieved and printed. The title for each index is taken
+# from the last argument in the \newindex command.
+# While processing \index and \printindex commands, if no argument is given the index entries
+# are built into a default index. The title of the default index is simply "Index".
+# This makes the difference between single- and multiple-index processing trivial.
+#
+# Another method can be used by omitting the \printindex command and just using \include to
+# pull in index files created by the makeindex program. These files will start with
+# \begin{theindex}. This command is used to determine where to print the index. Using this
+# approach, the indices will be output in the same order as the newindex commands were
+# originally found (see below). Using a combination of \printindex and \include{indexfile} has not
+# been tested and may produce undesireable results.
+#
+# The index data are stored in a hash for later sorting and output. As \printindex
+# commands are handled, the order in which they were found in the tex filea is saved,
+# associated with the ref argument to \printindex.
+#
+# We use the original %index hash to store the index data into. We append a \002 followed by the
+# name of the index to isolate the entries in different indices from each other. This is necessary
+# so that different indices can have entries with the same name. For the default index, the \002 is
+# appended without the name.
+#
+# Since the index order in the output cannot be determined if the \include{indexfile}
+# command is used, the order will be assumed from the order in which the \newindex
+# commands were originally seen in the TeX files. This order is saved as well as the
+# order determined from any printindex{ref} commands. If \printindex commnads are used
+# to specify the index output, that order will be used. If the \include{idxfile} command
+# is used, the order of the original newindex commands will be used. In this case the
+# default index will be printed last since it doesn't have a corresponding \newindex
+# command and its order cannot be determined. Mixing \printindex and \include{idxfile}
+# commands in the same file is likely to produce less than satisfactory results.
+#
+#
+# The hash containing index data is named %indices. It contains the following data:
+#{
+# 'title' => {
+# $ref1 => $indextitle ,
+# $ref2 => $indextitle ,
+# ...
+# },
+# 'newcmdorder' => [ ref1, ref2, ..., * ], # asterisk indicates the position of the default index.
+# 'printindorder' => [ ref1, ref2, ..., * ], # asterisk indicates the position of the default index.

+\chapter{Installing Bacula}
+\label{InstallChapter}
+\index[general]{Bacula!Installing}
+\index[general]{Installing Bacula}
+
+In general, you will need the Bacula source release, and if you want to run
+a Windows client, you will need the Bacula Windows binary release.
+However, Bacula needs certain third party packages (such as {\bf MySQL},
+{\bf PostgreSQL}, or {\bf SQLite} to build and run
+properly depending on the
+options you specify. Normally, {\bf MySQL} and {\bf PostgreSQL} are
+packages that can be installed on your distribution. However, if you do
+not have them, to simplify your task, we have combined a number of these
+packages into three {\bf depkgs} releases (Dependency Packages). This can
+vastly simplify your life by providing you with all the necessary packages
+rather than requiring you to find them on the Web, load them, and install
+them.
+
+\section{Source Release Files}
+\index[general]{Source Files}
+\index[general]{Release Files}
+ Beginning with Bacula 1.38.0, the source code has been broken into
+ four separate tar files each corresponding to a different module in
+ the Bacula SVN. The released files are:
+
+\begin{description}
+\item [bacula-2.2.8.tar.gz]
+ This is the primary source code release for Bacula. On each
+ release the version number (2.2.8) will be updated.
+
+\item [bacula-docs-2.2.8.tar.gz]
+ This file contains a copy of the docs directory with the
+ documents prebuild. English HTML directory, single HTML
+ file, and pdf file. The French and German translations
+ are in progress, but are not built.
+
+\item [bacula-gui-2.2.8.tar.gz]
+ This file contains the non-core GUI programs. Currently,
+ it contains bacula-web, a PHP program for producing management
+ viewing of your Bacula job status in a browser; and bimagemgr
+ a browser program for burning CDROM images with Bacula Volumes.
+
+\item [bacula-rescue-2.0.0.tar.gz]
+ This is the Bacula Rescue CDROM code. Note, the version number
+ of this package is not tied to the Bacula release version, so
+ it will be different. Using this code, you can burn a CDROM
+ with your system configuration and containing a statically
+ linked version of the File daemon. This can permit you to easily
+ repartition and reformat your hard disks and reload your
+ system with Bacula in the case of a hard disk failure.
+ Unfortunately this rescue disk does not properly boot for
+ all Linux distributions. The problem is that the boot procedure
+ can vary significantly between distributions, and even within
+ a distribution, they are a moving target.
+
+ This package evolves slower than the Bacula source code,
+ so there may not always be a new release of the rescue package when
+ making minor updates to the Bacula code. For example, when releasing
+ Bacula version 2.2.8, the rescue package may still be at version
+ 2.0.0 if there were no updates.
+
+\item [winbacula-2.2.8.exe]
+ This file is the 32 bit Windows installer for installing
+ the Windows client (File daemon) on a Windows machine.
+ This client will also run on 64 bit Windows machines.
+ Beginning with Bacula version 1.39.20, this executable will
+ also optionally load the Win32 Director and the Win32
+ Storage daemon.
+
+\end{description}

+\section{Upgrading Bacula}
+\index[general]{Bacula!Upgrading}
+\index[general]{Upgrading Bacula}
+\index[general]{Upgrading}
+
+If you are upgrading from one Bacula version to another, you should first
+carefully read the ReleaseNotes of all major versions between your current
+version and the version to which you are upgrading. If the Bacula catalog
+database has been upgraded (as it is almost every major release), you will
+either need to reinitialize your database starting from scratch (not
+normally a good idea), or save an ASCII copy of your database, then proceed
+to upgrade it. If you are upgrading two major versions (e.g. 1.36 to 2.0)
+then life will be more complicated because you must do two database
+upgrades. See below for more on this.
+
+Upgrading the catalog is normally done after Bacula is build and installed
+by:
+
+\begin{verbatim}
+cd <installed-scripts-dir> (default /etc/bacula)
+./update_bacula_tables
+\end{verbatim}
+
+This update script can also be find in the Bacula source src/cats
+directory.
+
+If there are several database upgrades between your version and the
+version to which you are upgrading, you will need to apply each database
+upgrade script. For your convenience, you can find all the old upgrade scripts
+in the {\bf upgradedb} directory of the source code. You will need to edit the
+scripts to correspond to your system configuration. The final upgrade script,
+if any, can be applied as noted above.
+
+If you are upgrading from one major version to another, you will need to
+replace all your components at the same time as generally the inter-daemon
+protocol will change. However, within any particular release (e.g. version
+1.32.x) unless there is an oversight or bug, the daemon protocol will not
+change. If this is confusing, simply read the ReleaseNotes very carefully as
+they will note if all daemons must be upgraded at the same time.
+
+Finally, please note that in general it is not necessary or desirable
+to do a {\bf make uninstall} before doing an upgrade providing you are careful
+not to change the installation directories. In fact, if you do so, you will
+most likely delete all your conf files, which could be disastrous.
+The normal procedure during an upgrade is simply:
+
+\begin{verbatim}
+./configure (your options)
+make
+make install
+\end{verbatim}
+
+In general none of your existing .conf or .sql files will be overwritten,
+and you must do both the {\bf make} and {\bf make install} commands, a
+{\bf make install} without the preceding {\bf make} will not work.
+
+For additional information on upgrading, please see the \ilink{Upgrading Bacula
+Versions}{upgrading} in the Tips chapter of this manual.
+
+\section{Releases Numbering}
+\index[general]{Release Numbering}
+\index[general]{Version Numbering}
+Every Bacula release whether beta or production has a different number
+as well as the date of the release build. The numbering system follows
+traditional Open Source conventions in that it is of the form.
+
+\begin{verbatim}
+major.minor.release
+\end{verbatim}
+
+For example:
+\begin{verbatim}
+1.38.11
+\end{verbatim}
+
+where each component (major, minor, patch) is a number.
+The major number is currently 1 and normally does not change
+very frequently. The minor number starts at 0 and increases
+each for each production release by 2 (i.e. it is always an
+even number for a production release), and the patch number is
+starts at zero each time the minor number changes. The patch
+number is increased each time a bug fix (or fixes) is released
+to production.
+
+So, as of this date (10 September 2006), the current production Bacula
+release is version 1.38.11. If there are bug fixes, the next release
+will be 1.38.12 (i.e. the patch number has increased by one).
+
+For all patch releases where the minor version number does not change,
+the database and all the daemons will be compatible. That means that
+you can safely run a 1.38.0 Director with a 1.38.11 Client. Of course,
+in this case, the Director may have bugs that are not fixed. Generally,
+within a minor release (some minor releases are not so minor), all
+patch numbers are officially released to production. This means that while
+the current Bacula version is 1.38.11, versions 1.38.0, 1.38.1, ... 1.38.10
+have all been previously released.
+
+When the minor number is odd, it indicates that the package is under
+development and thus may not be stable. For example, while the current
+production release of Bacula is currently 1.38.11, the current development
+version is 1.39.22. All patch versions of the development code are
+available in the SVN (source repository). However, not all patch versions
+of the development code (odd minor version) are officially released. When
+they are released, they are released as beta versions (see below for a
+definition of what beta means for Bacula releases).
+
+In general when the minor number increases from one production release
+to the next (i.e. 1.38.x to 1.40.0), the catalog database must be upgraded,
+the Director and Storage daemon must always be on the same minor release
+number, and often (not always), the Clients must also be on the same minor
+release. As often as possible, we attempt to make new releases that are
+downwards compatible with prior clients, but this is not always possible.
+You must check the release notes. In general, you will have fewer problems
+if you always run all the components on the same minor version number (i.e.
+all either 1.38.x or 1.40.x but not mixed).
+
+
+\label{BetaReleases}
+\section*{Beta Releases}
+\index[general]{Beta Releases}
+Towards the end of the development cycle, which typically runs
+one year from a major release to another, there will be several beta
+releases of the development code prior to a production release.
+As noted above, beta versions always have odd minor version numbers
+(e.g 1.37.x or 1.39.x).
+The purpose of the beta releases is to allow early adopter users to test
+the new code. Beta releases are made with the following considerations:
+
+\begin{itemize}
+\item The code passes the regression testing on FreeBSD, Linux, and Solaris
+ machines.
+
+\item There are no known major bugs, or on the rare occasion that
+ there are, they will be documented or already in the bugs database.
+
+\item Some of the new code/features may not yet be tested.
+
+\item Bugs are expected to be found, especially in the new
+ code before the final production release.
+
+\item The code will have been run in production in at least one small
+ site (mine).
+
+\item The Win32 client will have been run in production at least
+ one night at that small site.
+
+\item The documentation in the manual is unlikely to be complete especially
+ for the new features, and the Release Notes may not be fully
+ organized.
+
+\item Beta code is not generally recommended for everyone, but
+ rather for early adopters.
+\end{itemize}
+
+
+\label{Dependency}
+\section{Dependency Packages}
+\index[general]{Dependency Packages}
+\index[general]{Packages!Dependency}
+
+As discussed above, we have combined a number of third party packages that
+Bacula might need into the {\bf depkgs} release. You can,
+of course, get the latest packages from the original authors or
+from your operating system supplier. The locations of
+where we obtained the packages are in the README file in each package.
+However, be aware that the packages in the depkgs files have been tested by us
+for compatibility with Bacula.
+
+Typically, a dependency package will be named {\bf depkgs-ddMMMyy.tar.gz}
+where {\bf dd} is the day we release it, {\bf MMM}
+is the abbreviated month (e.g. Jan), and {\bf yy} is the year. An actual
+example is: {\bf depkgs-07Apr02.tar.gz}. To install and build this package (if
+needed), you do the following:
+
+\begin{enumerate}
+\item Create a {\bf bacula} directory, into which you will place both the
+ Bacula source as well as the dependency package.
+\item Detar the {\bf depkgs} into the {\bf bacula} directory.
+\item cd bacula/depkgs
+\item make
+\end{enumerate}
+
+Although the exact composition of the dependency packages may change from time
+to time, the current makeup is the following:
+
+\addcontentsline{lot}{table}{Dependency Packages}
+\begin{longtable}{|l|l|l|}

+\end{longtable}
+
+Note, some of these packages are quite large, so that building them can be a
+bit time consuming. The above instructions will build all the packages
+contained in the directory. However, when building Bacula, it will take only
+those pieces that it actually needs.
+
+Alternatively, you can make just the packages that are needed. For example,
+
+\footnotesize
+\begin{verbatim}
+cd bacula/depkgs
+make sqlite
+\end{verbatim}
+\normalsize
+
+will configure and build only the SQLite package.
+
+You should build the packages that you will require in {\bf depkgs} a
+prior to configuring and building Bacula, since Bacula will need
+them during the build process.
+
+For more information on the {\bf depkgs-qt} package, please read the
+INSTALL file in the main directory of that package. If you are going to
+build Qt4 using {\bf depkgs-qt}, you must source the {\bf qt4-paths} file
+included in the package prior to building Bacula. Please read the INSTALL
+file for more details.
+
+Even if you do not use SQLite, you might find it worthwhile to build {\bf mtx}
+because the {\bf tapeinfo} program that comes with it can often provide you
+with valuable information about your SCSI tape drive (e.g. compression,
+min/max block sizes, ...). Note, most distros provide {\bf mtx} as part of
+their release.
+
+The {\bf depkgs1} package is depreciated and previously contained
+readline, which should be available on all operating systems.
+
+The {\bf depkgs-win32} package is deprecated and no longer used in
+Bacula version 1.39.x and later. It was previously used to build
+the native Win32 client program, but this program is now built on Linux
+systems using cross-compiling. All the tools and third party libraries
+are automatically downloaded by executing the appropriate scripts. See
+src/win32/README.mingw32 for more details.

+
+Please see the
+\ilink{ Supported Operating Systems}{SupportedOSes} section
+of the QuickStart chapter of this manual.
+
+\section{Building Bacula from Source}
+\label{Building}
+\index[general]{Source!Building Bacula from}
+\index[general]{Building Bacula from Source}
+
+The basic installation is rather simple.
+
+\begin{enumerate}
+\item Install and build any {\bf depkgs} as noted above. This
+ should be unnecessary on most modern Operating Systems.
+
+\item Configure and install MySQL or PostgreSQL (if desired).
+ \ilink{Installing and Configuring MySQL Phase I}{MySqlChapter} or
+ \ilink{Installing and Configuring PostgreSQL Phase
+ I}{PostgreSqlChapter}. If you are installing from rpms, and are
+ using MySQL, please be sure to install {\bf mysql-devel}, so that the MySQL
+ header files are available while compiling Bacula. In addition, the MySQL
+ client library {\bf mysqlclient} requires the gzip compression library {\bf
+ libz.a} or {\bf libz.so}. If you are using rpm packages, these libraries are
+ in the {\bf libz-devel} package. On Debian systems, you will need to load the
+ {\bf zlib1g-dev} package. If you are not using rpms or debs, you will need to
+ find the appropriate package for your system.
+
+ Note, if you already have a running MySQL or PostgreSQL on your system, you
+ can skip this phase provided that you have built the thread safe libraries.
+ And you have already installed the additional rpms noted above.
+
+ SQLite is not supported on Solaris. This is because it
+ frequently fails with bus errors. However SQLite3 may work.
+
+\item Detar the Bacula source code preferably into the {\bf bacula} directory
+ discussed above.
+
+\item {\bf cd} to the directory containing the source code.
+
+\item ./configure (with appropriate options as described below). Any
+ path names you specify as options on the ./configure command line
+ must be absolute paths and not relative.
+
+\item Check the output of ./configure very carefully, especially the Install
+ binaries and Install config directories. If they are not correct,
+ please rerun ./configure until they are. The output from ./configure is
+ stored in {\bf config.out} and can be re-displayed at any time without
+ rerunning the ./configure by doing {\bf cat config.out}.
+
+\item If after running ./configure once, you decide to change options and
+ re-run it, that is perfectly fine, but before re-running it, you should run:
+
+\footnotesize
+\begin{verbatim}
+ make distclean
+\end{verbatim}
+\normalsize
+
+so that you are sure to start from scratch and not have a mixture of the two
+options. This is because ./configure caches much of the information. The {\bf
+make distclean} is also critical if you move the source directory from one
+machine to another. If the {\bf make distclean} fails, just ignore it and
+continue on.
+
+\item make
+ If you get errors while linking in the Storage daemon directory
+ (src/stored), it is probably because you have not loaded the static
+ libraries on your system. I noticed this problem on a Solaris system.
+ To correct it, make sure that you have not added {\bf
+ {-}{-}enable-static-tools} to the {\bf ./configure} command.
+
+ If you skip this step ({\bf make}) and proceed immediately to the {\bf
+ make install} you are making two serious errors: 1. your install will
+ fail because Bacula requires a {\bf make} before a {\bf make install}.
+ 2. you are depriving yourself of the chance to make sure there are no
+ errors before beginning to write files to your system directories.
+
+
+\item make install
+ Please be sure you have done a {\bf make} before entering this command,
+ and that everything has properly compiled and linked without errors.
+
+
+\item If you are new to Bacula, we {\bf strongly} recommend that you skip
+ the next step and use the default configuration files, then run the
+ example program in the next chapter, then come back and modify your
+ configuration files to suit your particular needs.
+
+\item Customize the configuration files for each of the three daemons
+ (Directory, File, Storage) and for the Console program. For the details
+ of how to do this, please see \ilink{Setting Up Bacula Configuration
+ Files}{ConfigureChapter} in the Configuration chapter of this manual. We
+ recommend that you start by modifying the default configuration files
+ supplied, making the minimum changes necessary. Complete customization
+ can be done after you have Bacula up and running. Please take care when
+ modifying passwords, which were randomly generated, and the {\bf Name}s
+ as the passwords and names must agree between the configuration files
+ for security reasons.
+
+\label{CreateDatabase}
+\item Create the Bacula MySQL database and tables
+ (if using MySQL)
+ \ilink{Installing and Configuring MySQL Phase II}{mysql_phase2} or
+ create the Bacula PostgreSQL database and tables
+ \ilink{Configuring PostgreSQL
+ II}{PostgreSQL_configure} or alternatively if you are using
+ SQLite \ilink{Installing and Configuring SQLite Phase II}{phase2}.
+
+\item Start Bacula ({\bf ./bacula start}) Note. the next chapter shows you
+ how to do this in detail.
+
+\item Interface with Bacula using the Console program
+
+\item For the previous two items, please follow the instructions in the
+ \ilink{Running Bacula}{TutorialChapter} chapter of this manual,
+ where you will run a simple backup and do a restore. Do this before you make
+ heavy modifications to the configuration files so that you are sure that
+ Bacula works and are familiar with it. After that changing the conf files
+ will be easier.
+
+\item If after installing Bacula, you decide to "move it", that is to
+ install it in a different set of directories, proceed as follows:
+
+\footnotesize
+\begin{verbatim}
+ make uninstall
+ make distclean
+ ./configure (your-new-options)
+ make
+ make install
+
+\end{verbatim}
+\normalsize
+
+\end{enumerate}
+
+If all goes well, the {\bf ./configure} will correctly determine which
+operating system you are running and configure the source code appropriately.
+Currently, FreeBSD, Linux (Red Hat), and Solaris are supported. The Bacula
+client (File daemon) is reported to work with MacOS X 10.3 is if
+readline support is not enabled (default) when building the client.
+
+If you install Bacula on more than one system, and they are identical, you can
+simply transfer the source tree to that other system and do a "make
+install". However, if there are differences in the libraries or OS versions,
+or you wish to install on a different OS, you should start from the original
+compress tar file. If you do transfer the source tree, and you have previously
+done a ./configure command, you MUST do:
+
+\footnotesize
+\begin{verbatim}
+make distclean
+\end{verbatim}
+\normalsize
+
+prior to doing your new ./configure. This is because the GNU autoconf tools
+cache the configuration, and if you re-use a configuration for a Linux machine
+on a Solaris, you can be sure your build will fail. To avoid this, as
+mentioned above, either start from the tar file, or do a "make distclean".
+
+In general, you will probably want to supply a more complicated {\bf
+configure} statement to ensure that the modules you want are built and that
+everything is placed into the correct directories.
+
+For example, on Fedora, Red Hat, or SuSE one could use the following:
+
+\footnotesize
+\begin{verbatim}
+CFLAGS="-g -Wall" \
+ ./configure \
+ --sbindir=$HOME/bacula/bin \
+ --sysconfdir=$HOME/bacula/bin \
+ --with-pid-dir=$HOME/bacula/bin/working \
+ --with-subsys-dir=$HOME/bacula/bin/working \
+ --with-mysql \
+ --with-working-dir=$HOME/bacula/bin/working \
+ --with-dump-email=$USER
+\end{verbatim}
+\normalsize
+
+The advantage of using the above configuration to start is that
+everything will be put into a single directory, which you can later delete
+once you have run the examples in the next chapter and learned how Bacula
+works. In addition, the above can be installed and run as non-root.
+
+For the developer's convenience, I have added a {\bf defaultconfig} script to
+the {\bf examples} directory. This script contains the statements that you
+would normally use, and each developer/user may modify them to suit his needs.
+You should find additional useful examples in this directory as well.
+
+The {\bf \verb:--:enable-conio} or {\bf \verb:--:enable-readline} options are useful because
+they provide a command line history and editing capability for the Console
+program. If you have included either option in the build, either the {\bf
+termcap} or the {\bf ncurses} package will be needed to link. On most
+systems, including Red Hat and SuSE, you should include the ncurses package.
+If Bacula's configure process finds the ncurses libraries, it will use
+those rather than the termcap library.
+On some systems, such as SuSE, the termcap library is not in the standard
+library directory. As a consequence, the option may be disabled or you may
+get an error message such as:
+
+\footnotesize
+\begin{verbatim}
+/usr/lib/gcc-lib/i586-suse-linux/3.3.1/.../ld:
+cannot find -ltermcap
+collect2: ld returned 1 exit status
+\end{verbatim}
+\normalsize
+
+while building the Bacula Console. In that case, you will need to set the {\bf
+LDFLAGS} environment variable prior to building.
+
+\footnotesize
+\begin{verbatim}
+export LDFLAGS="-L/usr/lib/termcap"
+\end{verbatim}
+\normalsize
+
+The same library requirements apply if you wish to use the readline
+subroutines for command line editing and history or
+if you are using a MySQL library that requires encryption. If you need encryption,
+you can either export the appropriate additional library options as shown
+above or, alternatively, you can include them directly on the ./configure line
+as in:
+
+\footnotesize
+\begin{verbatim}
+LDFLAGS="-lssl -lcyrpto" \
+ ./configure <your-options>
+\end{verbatim}
+\normalsize
+
+On some systems such as Mandriva, readline tends to
+gobble up prompts, which makes it totally useless. If this happens to you, use
+the disable option, or if you are using version 1.33 and above try using {\bf
+\verb:--:enable-conio} to use a built-in readline replacement. You will still need
+either the termcap or the ncurses library, but it is unlikely that the {\bf conio}
+package will gobble up prompts.
+
+readline is no longer supported after version 1.34. The code within Bacula
+remains, so it should be usable, and if users submit patches for it, we will
+be happy to apply them. However, due to the fact that each version of
+readline seems to be incompatible with previous versions, and that there
+are significant differences between systems, we can no longer afford to
+support it.
+
+\section{What Database to Use?}
+\label{DB}
+\index[general]{What Database to Use?}
+\index[general]{Use!What Database to}
+
+Before building Bacula you need to decide if you want to use SQLite, MySQL, or
+PostgreSQL. If you are not already running MySQL or PostgreSQL, you might
+want to start by testing with SQLite (not supported on Solaris).
+This will greatly simplify the setup for you
+because SQLite is compiled into Bacula an requires no administration. It
+performs well and is suitable for small to medium sized installations (maximum
+10-20 machines). However, we should note that a number of users have
+had unexplained database corruption with SQLite. For that reason, we
+recommend that you install either MySQL or PostgreSQL for production
+work.
+
+If you wish to use MySQL as the Bacula catalog, please see the
+\ilink{Installing and Configuring MySQL}{MySqlChapter} chapter of
+this manual. You will need to install MySQL prior to continuing with the
+configuration of Bacula. MySQL is a high quality database that is very
+efficient and is suitable for any sized installation. It is slightly more
+complicated than SQLite to setup and administer because it has a number of
+sophisticated features such as userids and passwords. It runs as a separate
+process, is truly professional and can manage a database of any size.
+
+If you wish to use PostgreSQL as the Bacula catalog, please see the
+\ilink{Installing and Configuring PostgreSQL}{PostgreSqlChapter}
+chapter of this manual. You will need to install PostgreSQL prior to
+continuing with the configuration of Bacula. PostgreSQL is very similar to
+MySQL, though it tends to be slightly more SQL92 compliant and has many more
+advanced features such as transactions, stored procedures, and the such. It
+requires a certain knowledge to install and maintain.
+
+If you wish to use SQLite as the Bacula catalog, please see
+\ilink{Installing and Configuring SQLite}{SqlLiteChapter} chapter of
+this manual. SQLite is not supported on Solaris.
+
+\section{Quick Start}
+\index[general]{Quick Start}
+\index[general]{Start!Quick}
+
+There are a number of options and important considerations given below
+that you can skip for the moment if you have not had any problems building
+Bacula with a simplified configuration as shown above.
+
+If the ./configure process is unable to find specific libraries (e.g.
+libintl, you should ensure that the appropriate package is installed on
+your system. Alternatively, if the package is installed in a non-standard
+location (as far as Bacula is concerned), then there is generally an
+option listed below (or listed with "./configure {-}{-}help" that will
+permit you to specify the directory that should be searched. In other
+cases, there are options that will permit you to disable to feature
+(e.g. {-}{-}disable-nls).
+
+If you want to dive right into it, we recommend you skip to the next chapter,
+and run the example program. It will teach you a lot about Bacula and as an
+example can be installed into a single directory (for easy removal) and run as
+non-root. If you have any problems or when you want to do a real installation,
+come back to this chapter and read the details presented below.
+
+\section{Configure Options}
+\label{Options}
+\index[general]{Options!Configure}
+\index[general]{Configure Options}
+
+The following command line options are available for {\bf configure} to
+customize your installation.
+
+\begin{description}
+\item [ {-}prefix=\lt{}patch\gt{}]
+ \index[general]{{-}prefix}
+ This option is meant to allow you to direct where the architecture
+ independent files should be placed. However, we find this a somewhat
+ vague concept, and so we have not implemented this option other than
+ what ./configure does by default. As a consequence, we suggest that
+ you avoid it. We have provided options that allow you to explicitly
+ specify the directories for each of the major categories of installation
+ files.
+\item [ {-}{-}sbindir=\lt{}binary-path\gt{}]
+ \index[general]{{-}{-}sbindir}
+ Defines where the Bacula binary (executable) files will be placed during a
+ {\bf make install} command.
+
+\item [ {-}{-}sysconfdir=\lt{}config-path\gt{}]
+ \index[general]{{-}{-}sysconfdir}
+ Defines where the Bacula configuration files should be placed during a
+ {\bf make install} command.
+
+\item [ {-}{-}mandir=\lt{}path\gt{}]
+ \index[general]{{-}{-}mandir}
+ Note, as of Bacula version 1.39.14, the meaning of any path
+ specified on this option is change from prior versions. It
+ now specifies the top level man directory.
+ Previously the mandir specified the full path to where you
+ wanted the man files installed.
+ The man files will be installed in gzip'ed format under
+ mandir/man1 and mandir/man8 as appropriate.
+ For the install to succeed you must have {\bf gzip} installed
+ on your system.
+
+ By default, Bacula will install the Unix man pages in
+ /usr/share/man/man1 and /usr/share/man/man8.
+ If you wish the man page to be installed in
+ a different location, use this option to specify the path.
+ Note, the main HTML and PDF Bacula documents are in a separate
+ tar file that is not part of the source distribution.
+
+\item [ {-}{-}datadir=\lt{}path\gt{} ]
+ \index[general]{{-}{-}datadir}
+ If you translate Bacula or parts of Bacula into a different language
+ you may specify the location of the po files using the {\bf
+ {-}{-}datadir} option. You must manually install any po files as
+ Bacula does not (yet) automatically do so.
+
+\item [ {-}{-}disable-ipv6 ]
+ \index[general]{{-}{-}disable-ipv6}
+
+\item [ {-}{-}enable-smartalloc ]
+ \index[general]{{-}{-}enable-smartalloc}
+ This enables the inclusion of the Smartalloc orphaned buffer detection
+ code. This option is highly recommended. Because we never build
+ without this option, you may experience problems if it is not enabled.
+ In this case, simply re-enable the option. We strongly recommend
+ keeping this option enabled as it helps detect memory leaks. This
+ configuration parameter is used while building Bacula
+
+\item [ {-}{-}enable-bat ]
+ \label{enablebat}
+ \index[general]{{-}{-}enable-bat}
+ If you have Qt4 >= 4.2 installed on your computer including the
+ libqt4 and libqt4-devel (libqt4-dev on Debian) libraries, and you want
+ to use the Bacula Administration Tool (bat) GUI Console interface to
+ Bacula, you must specify this option. Doing so will build everything in
+ the {\bf src/qt-console} directory. The build with enable-bat will work
+ only with a full Bacula build (i.e. it will not work with a client-only
+ build). In addition to the Qt4 libraries, linking bat requires
+ the qwt package installed on your system. Please see the next
+ configure option (with-qwt) for how to build the qwt package.
+
+ Qt4 is available on OpenSUSE 10.2, CentOS 5, Fedora, and Debian. If it
+ is not available on your system, you can download the {\bf depkgs-qt}
+ package from the Bacula Source Forge download area and build it and
+ the qwt package, both of which are needed to build bat. See the
+ INSTALL file in that package for more details. In particular to use
+ the Qt4 built by {\bf depkgs-qt} you {bf must} source the file
+ {\bf qt4-paths}.
+
+\item [ {-}{-}with-qwt=\lt{}path\gt{} ]
+ \index[general]{{-}{-}with-qwt}
+ To build bat, you need the qwt graphics package installed on
+ your system. The path specified must be an absolute path and
+ not relative.
+
+ The qwt package is available for download from
+ the qwt project on Source Forge. If you wish, you may build and
+ install it on your system (by default in /usr/lib).
+ If you have done so, you would specify:
+
+\begin{verbatim}
+ --with-qwt=/usr/lib/qwt-5.0.2
+\end{verbatim}
+
+ Alternatively, you can download the Bacula depkgs package (currently
+ version 11Jul07) and build it, then assuming that you have put it
+ into a directory named bacula, you would specify:
+
+\begin{verbatim}
+ --with-qwt=$HOME/bacula/depkgs/qwt
+\end{verbatim}
+
+ Some packages such as Debian do not adhere to the standard of
+ naming the library libqwt.a or libqwt.so, and you will either need
+ to manually add a soft link to the name they use or use the
+ depkgs version, which handles the naming correctly.
+
+
+\item [ {-}{-}enable-batch-insert ]
+ \index[general]{{-}{-}enable-batch-insert}
+ This option enables batch inserts of the attribute records (default) in
+ the catalog database, which is much faster (10 times or more) than
+ without this option for large numbers of files. However, this option
+ will automatically be disabled if your SQL libraries are not
+ thread safe. If you find that batch mode is not enabled on your Bacula
+ installation, then your database most likely does not support threads.
+
+ SQLite2 is not thread safe. Batch insert cannot be enabled when using
+ SQLite2
+
+ On most systems, MySQL, PostgreSQL and SQLite3 are thread safe.
+
+ To verify that your PostgreSQL is thread safe, you can try this
+ (change the path to point to your particular installed libpq.a;
+ these commands were issued on FreeBSD 6.2):
+
+\begin{verbatim}
+$ nm /usr/local/lib/libpq.a | grep PQputCopyData
+00001b08 T PQputCopyData
+$ nm /usr/local/lib/libpq.a | grep mutex
+ U pthread_mutex_lock
+ U pthread_mutex_unlock
+ U pthread_mutex_init
+ U pthread_mutex_lock
+ U pthread_mutex_unlock
+\end{verbatim}
+
+ The above example shows a libpq that contains the required function
+ PQputCopyData and is thread enabled (i.e. the pthread\_mutex* entries).
+ If you do not see PQputCopyData, your version of PostgreSQL is too old
+ to allow batch insert. If you do not see the mutex entries, then thread
+ support has not been enabled. Our tests indicate you usually need to
+ change the configuration options and recompile/reinstall the PostgreSQL
+ client software to get thread support.
+
+ Bacula always links to the thread safe MySQL libraries.
+
+ As a default, Bacula runs SQLite3 with {\bf PRAGMA synchronous=OFF}
+ because it improves performance by more than 30 times. However, it
+ increases the possibility of a corrupted database. If you want more
+ security, please modify src/version.h appropriately (it should be
+ obvious when you look at the file).
+
+ Running with Batch Insert turned on is recommended because it can
+ significantly improve attribute insertion times. However, it does
+ put a significantly larger part of the work on your SQL engine, so
+ you may need to pay more attention to tuning it. In particular,
+ Batch Insert can require large temporary table space, and consequently,
+ the default location (often /tmp) may run out of space causing errors.
+ For MySQL, the location is set in my.conf with "tmpdir". You may also
+ want to increase the memory available to your SQL engine to further
+ improve performance during Batch Inserts.
+
+\item [ {-}{-}enable-gnome ]
+ \index[general]{{-}{-}enable-gnome}
+ If you have GNOME installed on your computer including the
+ GNOME development libraries, and you want to use the
+ GNOME GUI Console interface to Bacula, you must specify this option.
+ Doing so will build everything in the {\bf src/gnome2-console} directory.
+
+\item [ {-}{-}enable-bwx-console ]
+ \index[general]{{-}{-}enable-bwx-console}
+ If you have wxWidgets installed on your computer and you want to use the
+ wxWidgets GUI Console interface to Bacula, you must specify this option.
+ Doing so will build everything in the {\bf src/wx-console} directory.
+ This could also be useful to users who want a GUI Console and don't want
+ to install GNOME, as wxWidgets can work with GTK+, Motif or even X11
+ libraries.
+
+\item [ {-}{-}enable-tray-monitor ]
+ \index[general]{{-}{-}enable-tray-monitor}
+ If you have GTK installed on your computer, you run a graphical
+ environment or a window manager compatible with the FreeDesktop system
+ tray standard (like KDE and GNOME) and you want to use a GUI to monitor
+ Bacula daemons, you must specify this option. Doing so will build
+ everything in the {\bf src/tray-monitor} directory. Note, due to
+ restrictions on what can be linked with GPLed code, we were forced to
+ remove the egg code that dealt with the tray icons and replace it by
+ calls to the GTK+ API, and unfortunately, the tray icon API necessary
+ was not implemented until GTK version 2.10 or later.
+
+\item [ {-}{-}enable-static-tools]
+ \index[general]{{-}{-}enable-static-tools}
+ This option causes the linker to link the Storage daemon utility tools
+ ({\bf bls}, {\bf bextract}, and {\bf bscan}) statically. This permits
+ using them without having the shared libraries loaded. If you have
+ problems linking in the {\bf src/stored} directory, make sure you have
+ not enabled this option, or explicitly disable static linking by adding
+ {\bf \verb:--:disable-static-tools}.
+
+\item [ {-}{-}enable-static-fd]
+ \index[general]{{-}{-}enable-static-fd}
+ This option causes the make process to build a {\bf static-bacula-fd} in
+ addition to the standard File daemon. This static version will include
+ statically linked libraries and is required for the Bare Metal recovery.
+ This option is largely superseded by using {\bf make static-bacula-fd}
+ from with in the {\bf src/filed} directory. Also, the {\bf
+ \verb:--:enable-client-only} option described below is useful for just
+ building a client so that all the other parts of the program are not
+ compiled.
+
+ When linking a static binary, the linker needs the static versions
+ of all the libraries that are used, so frequently users will
+ experience linking errors when this option is used. The first
+ thing to do is to make sure you have the static glibc library
+ installed on your system. The second thing to do is the make sure
+ you do not specify {\bf {-}{-}openssl} or {\bf {-}{-}with-python}
+ on your ./configure statement as these options require additional
+ libraries. You may be able to enable those options, but you will
+ need to load additional static libraries.
+
+
+\item [ {-}{-}enable-static-sd]
+ \index[general]{{-}{-}enable-static-sd}
+ This option causes the make process to build a {\bf static-bacula-sd} in
+ addition to the standard Storage daemon. This static version will
+ include statically linked libraries and could be useful during a Bare
+ Metal recovery.
+
+ When linking a static binary, the linker needs the static versions
+ of all the libraries that are used, so frequently users will
+ experience linking errors when this option is used. The first
+ thing to do is to make sure you have the static glibc library
+ installed on your system. The second thing to do is the make sure
+ you do not specify {\bf {-}{-}openssl} or {\bf {-}{-}with-python}
+ on your ./configure statement as these options require additional
+ libraries. You may be able to enable those options, but you will
+ need to load additional static libraries.
+
+
+\item [ {-}{-}enable-static-dir]
+ \index[general]{{-}{-}enable-static-dir}
+ This option causes the make process to build a {\bf static-bacula-dir}
+ in addition to the standard Director. This static version will include
+ statically linked libraries and could be useful during a Bare Metal
+ recovery.
+
+ When linking a static binary, the linker needs the static versions
+ of all the libraries that are used, so frequently users will
+ experience linking errors when this option is used. The first
+ thing to do is to make sure you have the static glibc library
+ installed on your system. The second thing to do is the make sure
+ you do not specify {\bf {-}{-}openssl} or {\bf {-}{-}with-python}
+ on your ./configure statement as these options require additional
+ libraries. You may be able to enable those options, but you will
+ need to load additional static libraries.
+
+
+\item [ {-}{-}enable-static-cons]
+ \index[general]{{-}{-}enable-static-cons}
+ This option causes the make process to build a {\bf static-console} and
+ a {\bf static-gnome-console} in addition to the standard console. This
+ static version will include statically linked libraries and could be
+ useful during a Bare Metal recovery.
+
+ When linking a static binary, the linker needs the static versions
+ of all the libraries that are used, so frequently users will
+ experience linking errors when this option is used. The first
+ thing to do is to make sure you have the static glibc library
+ installed on your system. The second thing to do is the make sure
+ you do not specify {\bf {-}{-}openssl} or {\bf {-}{-}with-python}
+ on your ./configure statement as these options require additional
+ libraries. You may be able to enable those options, but you will
+ need to load additional static libraries.
+
+
+\item [ {-}{-}enable-client-only]
+ \index[general]{{-}{-}enable-client-only}
+ This option causes the make process to build only the File daemon and
+ the libraries that it needs. None of the other daemons, storage tools,
+ nor the console will be built. Likewise a {\bf make install} will then
+ only install the File daemon. To cause all daemons to be built, you
+ will need to do a configuration without this option. This option
+ greatly facilitates building a Client on a client only machine.

+
+\item [ {-}{-}enable-build-dird]
+ \index[general]{{-}{-}enable-build-dird}
+ This option causes the make process to build the Director and the
+ Director's tools. By default, this option is on, but you may turn
+ it off by using {\bf {-}{-}disable-build-dird} to prevent the
+ Director from being built.
+
+\item [ {-}{-}enable-build-stored]
+ \index[general]{{-}{-}enable-build-stored}
+ This option causes the make process to build the Storage daemon.
+ By default, this option is on, but you may turn
+ it off by using {\bf {-}{-}disable-build-stored} to prevent the
+ Storage daemon from being built.
+
+
+\item [ {-}{-}enable-largefile]
+ \index[general]{{-}{-}enable-largefile}
+ This option (default) causes Bacula to be built with 64 bit file address
+ support if it is available on your system. This permits Bacula to read and
+ write files greater than 2 GBytes in size. You may disable this feature and
+ revert to 32 bit file addresses by using {\bf \verb:--:disable-largefile}.
+
+\item [ {-}{-}disable-nls]
+ \index[general]{{-}{-}disable-nls}
+ By default, Bacula uses the GNU Native Language Support (NLS) libraries. On
+ some machines, these libraries may not be present or may not function
+ correctly (especially on non-Linux implementations). In such cases, you
+ may specify {\bf {-}{-}disable-nls} to disable use of those libraries.
+ In such a case, Bacula will revert to using English.
+
+\item [ {-}{-}disable-ipv6 ]
+ \index[general]{{-}{-}disable-ipv6}
+ By default, Bacula enables IPv6 protocol. On some systems, the files
+ for IPv6 may exist, but the functionality could be turned off in the
+ kernel. In that case, in order to correctly build Bacula, you will
+ explicitly need to use this option so that Bacula does not attempt
+ to reference OS function calls that do not exist.
+
+\item [ {-}{-}with-sqlite=\lt{}sqlite-path\gt{}]
+ \index[general]{{-}{-}with-sqlite}
+ This enables use of the SQLite version 2.8.x database. The {\bf
+ sqlite-path} is not normally specified as Bacula looks for the necessary
+ components in a standard location ({\bf depkgs/sqlite}). See
+ \ilink{Installing and Configuring SQLite}{SqlLiteChapter} chapter of
+ this manual for more details. SQLite is not supported on Solaris.
+
+ See the note below under the {-}{-}with-postgresql item.
+
+\item [ {-}{-}with-sqlite3=\lt{}sqlite3-path\gt{}]
+ \index[general]{{-}{-}with-sqlite3}
+ This enables use of the SQLite version 3.x database. The {\bf
+ sqlite3-path} is not normally specified as Bacula looks for the
+ necessary components in a standard location ({\bf depkgs/sqlite3}). See
+ \ilink{Installing and Configuring SQLite}{SqlLiteChapter} chapter of
+ this manual for more details. SQLite3 is not supported on Solaris.
+
+\item [ {-}{-}with-mysql=\lt{}mysql-path\gt{}]
+ \index[general]{{-}{-}with-mysql}
+ This enables building of the Catalog services for Bacula. It assumes
+ that MySQL is running on your system, and expects it to be installed in
+ the {\bf mysql-path} that you specify. Normally, if MySQL is installed
+ in a standard system location, you can simply use {\bf {-}{-}with-mysql}
+ with no path specification. If you do use this option, please proceed
+ to installing MySQL in the \ilink{Installing and Configuring
+ MySQL}{MySqlChapter} chapter before proceeding with the configuration.
+
+ See the note below under the {-}{-}with-postgresql item.
+
+\item [ {-}{-}with-postgresql=\lt{}path\gt{}]
+ \index[general]{{-}{-}with-postgresql}
+ This provides an explicit path to the PostgreSQL libraries if Bacula
+ cannot find it by default. Normally to build with PostgreSQL, you would
+ simply use {\bf {-}{-}with-postgresql}.
+
+ Note, for Bacula to be configured properly, you must specify one
+ of the four database options supported. That is:
+ {-}{-}with-sqlite, {-}{-}with-sqlite3, {-}{-}with-mysql, or
+ {-}{-}with-postgresql, otherwise the ./configure will fail.
+
+\item [ {-}{-}with-openssl=\lt{}path\gt{}]
+ This configuration option is necessary if you want to enable TLS (ssl),
+ which encrypts the communications within
+ Bacula or if you want to use File Daemon PKI data encryption.
+ Normally, the {\bf path} specification is not necessary since
+ the configuration searches for the OpenSSL libraries in standard system
+ locations. Enabling OpenSSL in Bacula permits secure communications
+ between the daemons and/or data encryption in the File daemon.
+ For more information on using TLS, please see the
+ \ilink{Bacula TLS -- Communications Encryption}{CommEncryption} chapter
+ of this manual.
+ For more information on using PKI data encryption, please see the
+ \ilink{Bacula PKI -- Data Encryption}{DataEncryption}
+ chapter of this manual.
+
+\item [ {-}{-}with-python=\lt{}path\gt{}]
+ \index[general]{{-}{-}with-python}
+ This option enables Bacula support for Python. If no path is supplied,
+ configure will search the standard library locations for Python 2.2,
+ 2.3, 2.4, or 2.5. If it cannot find the library, you will need to
+ supply a path to your Python library directory. Please see the
+ \ilink{Python chapter}{PythonChapter} for the details of using Python
+ scripting.
+
+\item [ {-}{-}with-libintl-prefix=\lt{}DIR\gt{}]
+ \index[general]{{-}{-}with-libintl-prefix}
+ This option may be used to tell Bacula to search DIR/include and
+ DIR/lib for the libintl headers and libraries needed for Native
+ Language Support (NLS).
+
+\item [ {-}{-}enable-conio]
+ \index[general]{{-}{-}enable-conio}
+ Tells Bacula to enable building the small, light weight readline
+ replacement routine. It is generally much easier to configure than
+ readline, although, like readline, it needs either the termcap or
+ ncurses library.
+
+\item [ {-}{-}with-readline=\lt{}readline-path\gt{}]
+ \index[general]{{-}{-}with-readline}
+ Tells Bacula where {\bf readline} is installed. Normally, Bacula will
+ find readline if it is in a standard library. If it is not found and no
+ {-}{-}with-readline is specified, readline will be disabled. This
+ option affects the Bacula build. Readline provides the Console program
+ with a command line history and editing capability and is no longer
+ supported, so you are on your own if you have problems.
+
+\item [ {-}{-}enable-readline]
+ \index[general]{{-}{-}enable-readline}
+ Tells Bacula to enable readline support. It is normally disabled due to the
+ large number of configuration problems and the fact that the package seems to
+ change in incompatible ways from version to version.
+
+\item [ {-}{-}with-tcp-wrappers=\lt{}path\gt{}]
+ \index[general]{{-}{-}with-tcp-wrappers}
+ \index[general]{TCP Wrappers}
+ \index[general]{Wrappers!TCP}
+ \index[general]{libwrappers}
+ This specifies that you want TCP wrappers (man hosts\_access(5)) compiled in.
+ The path is optional since Bacula will normally find the libraries in the
+ standard locations. This option affects the Bacula build. In specifying your
+ restrictions in the {\bf /etc/hosts.allow} or {\bf /etc/hosts.deny} files, do
+ not use the {\bf twist} option (hosts\_options(5)) or the Bacula process will
+ be terminated. Note, when setting up your {\bf /etc/hosts.allow}
+ or {\bf /etc/hosts.deny}, you must identify the Bacula daemon in
+ question with the name you give it in your conf file rather than the
+ name of the executable.
+
+ For more information on configuring and testing TCP wrappers, please see the
+ \ilink{Configuring and Testing TCP Wrappers}{wrappers} section
+ in the Security Chapter.
+
+ On SuSE, the libwrappers libraries needed to link Bacula are
+ contained in the tcpd-devel package. On Red Hat, the package is named
+ tcp\_wrappers.
+
+\item [ {-}{-}with-archivedir=\lt{}path\gt{} ]
+ \index[general]{{-}{-}with-archivedir}
+ The directory used for disk-based backups. Default value is /tmp.
+ This parameter sets the default values in the bacula-dir.conf and bacula-sd.conf
+ configuration files. For example, it sets the Where directive for the
+ default restore job and the Archive Device directive for the FileStorage
+ device.
+
+ This option is designed primarily for use in regression testing.
+ Most users can safely ignore this option.
+
+\item [ {-}{-}with-working-dir=\lt{}working-directory-path\gt{} ]
+ \index[general]{{-}{-}with-working-dir}
+ This option is mandatory and specifies a directory into which Bacula may
+ safely place files that will remain between Bacula executions. For example,
+ if the internal database is used, Bacula will keep those files in this
+ directory. This option is only used to modify the daemon configuration
+ files. You may also accomplish the same thing by directly editing them later.
+ The working directory is not automatically created by the install process, so
+ you must ensure that it exists before using Bacula for the first time.
+
+\item [ {-}{-}with-base-port=\lt{}port=number\gt{}]
+ \index[general]{{-}{-}with-base-port}
+ In order to run, Bacula needs three TCP/IP ports (one for the Bacula
+ Console, one for the Storage daemon, and one for the File daemon). The {\bf
+ \verb:--:with-baseport} option will automatically assign three ports beginning at
+ the base port address specified. You may also change the port number in the
+ resulting configuration files. However, you need to take care that the
+ numbers correspond correctly in each of the three daemon configuration
+ files. The default base port is 9101, which assigns ports 9101 through 9103.
+ These ports (9101, 9102, and 9103) have been officially assigned to Bacula by
+ IANA. This option is only used to modify the daemon configuration files. You
+ may also accomplish the same thing by directly editing them later.
+
+\item [ {-}{-}with-dump-email=\lt{}email-address\gt{}]
+ \index[general]{{-}{-}with-dump-email}
+ This option specifies the email address where any core dumps should be set.
+ This option is normally only used by developers.
+
+\item [ {-}{-}with-pid-dir=\lt{}PATH\gt{} ]
+ \index[general]{{-}{-}with-pid-dir}
+ This specifies where Bacula should place the process id file during
+ execution. The default is: {\bf /var/run}. This directory is not created by
+ the install process, so you must ensure that it exists before using Bacula
+ the first time.
+
+\item [ {-}{-}with-subsys-dir=\lt{}PATH\gt{}]
+ \index[general]{{-}{-}with-subsys-dir}
+ This specifies where Bacula should place the subsystem lock file during
+ execution. The default is {\bf /var/run/subsys}. Please make sure that you do
+ not specify the same directory for this directory and for the {\bf sbindir}
+ directory. This directory is used only within the autostart scripts. The
+ subsys directory is not created by the Bacula install, so you must be sure to
+ create it before using Bacula.
+
+\item [ {-}{-}with-dir-password=\lt{}Password\gt{}]
+ \index[general]{{-}{-}with-dir-password}
+ This option allows you to specify the password used to access the Director
+ (normally from the Console program). If it is not specified, configure will
+ automatically create a random password.
+
+\item [ {-}{-}with-fd-password=\lt{}Password\gt{} ]
+ \index[general]{{-}{-}with-fd-password}
+ This option allows you to specify the password used to access the File daemon
+ (normally called from the Director). If it is not specified, configure will
+ automatically create a random password.
+
+\item [ {-}{-}with-sd-password=\lt{}Password\gt{} ]
+ \index[general]{{-}{-}with-sd-password}
+ This option allows you to specify the password used to access the Storage daemon
+ (normally called from the Director). If it is not specified, configure will
+ automatically create a random password.
+
+\item [ {-}{-}with-dir-user=\lt{}User\gt{} ]
+ \index[general]{{-}{-}with-dir-user}
+ This option allows you to specify the Userid used to run the Director. The
+ Director must be started as root, but doesn't need to run as root, and
+ after doing preliminary initializations, it can "drop" to the UserId
+ specified on this option.
+ If you specify this option, you must
+ create the User prior to running {\bf make install}, because the
+ working directory owner will be set to {\bf User}.
+
+\item [ {-}{-}with-dir-group=\lt{}Group\gt{} ]
+ \index[general]{{-}{-}with-dir-group}
+ This option allows you to specify the GroupId used to run the Director. The
+ Director must be started as root, but doesn't need to run as root, and after
+ doing preliminary initializations, it can "drop" to the GroupId specified
+ on this option.
+ If you specify this option, you must

+ working directory group will be set to {\bf Group}.
+
+\item [ {-}{-}with-sd-user=\lt{}User\gt{} ]
+ \index[general]{{-}{-}with-sd-user}
+ This option allows you to specify the Userid used to run the Storage daemon.
+ The Storage daemon must be started as root, but doesn't need to run as root,
+ and after doing preliminary initializations, it can "drop" to the UserId
+ specified on this option. If you use this option, you will need to take care
+ that the Storage daemon has access to all the devices (tape drives, ...) that
+ it needs.
+
+\item [ {-}{-}with-sd-group=\lt{}Group\gt{} ]
+ \index[general]{{-}{-}with-sd-group}
+ This option allows you to specify the GroupId used to run the Storage daemon.
+ The Storage daemon must be started as root, but doesn't need to run as root,
+ and after doing preliminary initializations, it can "drop" to the GroupId
+ specified on this option.
+
+\item [ {-}{-}with-fd-user=\lt{}User\gt{} ]
+ \index[general]{{-}{-}with-fd-user}
+ This option allows you to specify the Userid used to run the File daemon. The
+ File daemon must be started as root, and in most cases, it needs to run as
+ root, so this option is used only in very special cases, after doing
+ preliminary initializations, it can "drop" to the UserId specified on this
+ option.
+
+\item [ {-}{-}with-fd-group=\lt{}Group\gt{} ]
+ \index[general]{{-}{-}with-fd-group}
+ This option allows you to specify the GroupId used to run the File daemon.
+ The File daemon must be started as root, and in most cases, it must be run as
+ root, however, after doing preliminary initializations, it can "drop" to
+ the GroupId specified on this option.
+
+\item [ {-}{-}with-mon-dir-password=\lt{}Password\gt{}]
+ \index[general]{{-}{-}with-mon-dir-password}
+ This option allows you to specify the password used to access the Directory

+ automatically create a random password.
+
+\item [ {-}{-}with-mon-fd-password=\lt{}Password\gt{} ]
+ \index[general]{{-}{-}with-mon-fd-password}
+ This option allows you to specify the password used to access the File daemon

+ automatically create a random password.
+
+\item [ {-}{-}with-mon-sd-password=\lt{}Password\gt{} ]
+ \index[general]{{-}{-}with-mon-sd-password}
+ This option allows you to specify the password used to access the

+ automatically create a random password.
+
+\item [ {-}{-}with-db-name=\lt{}database-name\gt{} ]
+ \index[general]{{-}{-}with-db-name}
+ This option allows you to specify the database name to be used in
+ the conf files. The default is bacula.
+
+\item [ {-}{-}with-db-user=\lt{}database-user\gt{} ]
+ \index[general]{{-}{-}with-db-user}

+\index[general]{Recommended Options for Most Systems}
+
+For most systems, we recommend starting with the following options:

+ --with-mysql=$HOME/mysql \
+ --with-working-dir=$HOME/bacula/working
+\end{verbatim}
+\normalsize
+
+If you want to install Bacula in an installation directory rather than run it
+out of the build directory (as developers will do most of the time), you
+should also include the \verb:--:sbindir and \verb:--:sysconfdir options with appropriate
+paths. Neither are necessary if you do not use "make install" as is the case
+for most development work. The install process will create the sbindir and
+sysconfdir if they do not exist, but it will not automatically create the
+pid-dir, subsys-dir, or working-dir, so you must ensure that they exist before
+running Bacula for the first time.
+
+\section{Red Hat}

+ --with-pid-dir=/var/run \
+ --enable-conio
+\end{verbatim}
+\normalsize
+
+Note, Bacula assumes that /var/bacula, /var/run, and /var/lock/subsys exist so
+it will not automatically create them during the install process.
+
+\section{Solaris}
+\index[general]{Solaris}
+
+To build Bacula from source, you will need the following installed on your
+system (they are not by default): libiconv, gcc 3.3.2, stdc++, libgcc (for
+stdc++ and gcc\_s libraries), make 3.8 or later.
+
+You will probably also need to: Add /usr/local/bin to PATH and Add
+/usr/ccs/bin to PATH for ar.
+
+It is possible to build Bacula on Solaris with the Solaris compiler, but
+we recommend using GNU C++ if possible.
+
+A typical configuration command might look like:
+
+\footnotesize
+\begin{verbatim}
+#!/bin/sh
+CFLAGS="-g" ./configure \
+ --sbindir=$HOME/bacula/bin \
+ --sysconfdir=$HOME/bacula/bin \
+ --with-mysql=$HOME/mysql \
+ --enable-smartalloc \
+ --with-pid-dir=$HOME/bacula/bin/working \
+ --with-subsys-dir=$HOME/bacula/bin/working \
+ --with-working-dir=$HOME/bacula/working
+\end{verbatim}
+\normalsize
+
+As mentioned above, the install process will create the sbindir and sysconfdir
+if they do not exist, but it will not automatically create the pid-dir,
+subsys-dir, or working-dir, so you must ensure that they exist before running
+Bacula for the first time.
+
+Note, you may need to install the following packages to build Bacula
+from source:
+\footnotesize
+\begin{verbatim}
+SUNWbinutils,
+SUNWarc,
+SUNWhea,
+SUNWGcc,
+SUNWGnutls
+SUNWGnutls-devel
+SUNWGmake
+SUNWgccruntime
+SUNWlibgcrypt
+SUNWzlib
+SUNWzlibs
+SUNWbinutilsS
+SUNWGmakeS
+SUNWlibm
+
+export
+PATH=/usr/bin::/usr/ccs/bin:/etc:/usr/openwin/bin:/usr/local/bin:/usr/sfw/bin:/opt/sfw/bin:/usr/ucb:/usr/sbin
+\end{verbatim}
+\normalsize
+
+If you have installed special software not normally in the Solaris
+libraries, such as OpenSSL, or the packages shown above, then you may need
+to add {\bf /usr/sfw/lib} to the library search path. Probably the
+simplest way to do so is to run:
+
+\footnotesize
+\begin{verbatim}
+setenv LDFLAGS "-L/usr/sfw/lib -R/usr/sfw/lib"
+\end{verbatim}
+\normalsize
+
+Prior to running the ./configure command.
+
+Alternatively, you can set the LD\_LIBARY\_PATH and/or the LD\_RUN\_PATH
+environment variables appropriately.
+
+It is also possible to use the {\bf crle} program to set the library
+search path. However, this should be used with caution.
+
+\section{FreeBSD}
+\index[general]{FreeBSD}
+
+Please see:
+\elink{The FreeBSD Diary}{http://www.freebsddiary.org/bacula.php} for a
+detailed description on how to make Bacula work on your system. In addition,
+users of FreeBSD prior to 4.9-STABLE dated Mon Dec 29 15:18:01 2003 UTC who
+plan to use tape devices, please see the
+\ilink{Tape Testing Chapter}{FreeBSDTapes} of this manual for
+{\bf important} information on how to configure your tape drive for
+compatibility with Bacula.
+
+If you are using Bacula with MySQL, you should take care to compile MySQL with
+FreeBSD native threads rather than LinuxThreads, since Bacula is normally built
+with FreeBSD native threads rather than LinuxTreads. Mixing the two will
+probably not work.
+

+exit 0
+\end{verbatim}
+\normalsize
+
+You may also want to put the following entries in your {\bf /etc/services}
+file as it will make viewing the connections made by Bacula easier to
+recognize (i.e. netstat -a):
+
+\footnotesize
+\begin{verbatim}

+\section{Installing Bacula}
+\index[general]{Bacula!Installing}
+\index[general]{Installing Bacula}
+
+Before setting up your configuration files, you will want to install Bacula in
+its final location. Simply enter:
+
+\footnotesize
+\begin{verbatim}
+make install
+\end{verbatim}
+\normalsize
+
+If you have previously installed Bacula, the old binaries will be overwritten,
+but the old configuration files will remain unchanged, and the "new"
+configuration files will be appended with a {\bf .new}. Generally if you have
+previously installed and run Bacula you will want to discard or ignore the
+configuration files with the appended {\bf .new}.
+
+\section{Building a File Daemon or Client}
+\index[general]{Client!Building a File Daemon or}
+\index[general]{Building a File Daemon or Client}
+
+If you run the Director and the Storage daemon on one machine and you wish to
+back up another machine, you must have a copy of the File daemon for that
+machine. If the machine and the Operating System are identical, you can simply
+copy the Bacula File daemon binary file {\bf bacula-fd} as well as its
+configuration file {\bf bacula-fd.conf} then modify the name and password in
+the conf file to be unique. Be sure to make corresponding additions to the
+Director's configuration file ({\bf bacula-dir.conf}).
+
+If the architecture or the OS level are different, you will need to build a
+File daemon on the Client machine. To do so, you can use the same {\bf
+./configure} command as you did for your main program, starting either from a
+fresh copy of the source tree, or using {\bf make\ distclean} before the {\bf
+./configure}.
+
+Since the File daemon does not access the Catalog database, you can remove
+the {\bf \verb:--:with-mysql} or {\bf \verb:--:with-sqlite} options, then
+add {\bf \verb:--:enable-client-only}. This will compile only the
+necessary libraries and the client programs and thus avoids the necessity
+of installing one or another of those database programs to build the File
+daemon. With the above option, you simply enter {\bf make} and just the
+client will be built.

+\index[general]{Auto Starting the Daemons}
+
+If you wish the daemons to be automatically started and stopped when your
+system is booted (a good idea), one more step is necessary. First, the
+./configure process must recognize your system -- that is it must be a
+supported platform and not {\bf unknown}, then you must install the platform
+dependent files by doing:
+
+\footnotesize
+\begin{verbatim}
+(become root)
+make install-autostart
+\end{verbatim}
+\normalsize
+
+Please note, that the auto-start feature is implemented only on systems
+that we officially support (currently, FreeBSD, Red Hat/Fedora Linux, and
+Solaris), and has only been fully tested on Fedora Linux.
+
+The {\bf make install-autostart} will cause the appropriate startup scripts
+to be installed with the necessary symbolic links. On Red Hat/Fedora Linux
+systems, these scripts reside in {\bf /etc/rc.d/init.d/bacula-dir} {\bf
+/etc/rc.d/init.d/bacula-fd}, and {\bf /etc/rc.d/init.d/bacula-sd}. However
+the exact location depends on what operating system you are using.
+
+If you only wish to install the File daemon, you may do so with:
+
+\footnotesize
+\begin{verbatim}
+make install-autostart-fd
+\end{verbatim}
+\normalsize
+
+\section{Other Make Notes}

+\index[general]{Other Make Notes}
+
+To simply build a new executable in any directory, enter:
+
+\footnotesize
+\begin{verbatim}
+make
+\end{verbatim}
+\normalsize
+
+To clean out all the objects and binaries (including the files named 1, 2, or
+3, which are development temporary files), enter:
+
+\footnotesize
+\begin{verbatim}
+make clean
+\end{verbatim}
+\normalsize
+
+To really clean out everything for distribution, enter:
+
+\footnotesize
+\begin{verbatim}
+make distclean
+\end{verbatim}
+\normalsize
+
+note, this cleans out the Makefiles and is normally done from the top level
+directory to prepare for distribution of the source. To recover from this
+state, you must redo the {\bf ./configure} in the top level directory, since
+all the Makefiles will be deleted.
+
+To add a new file in a subdirectory, edit the Makefile.in in that directory,
+then simply do a {\bf make}. In most cases, the make will rebuild the Makefile
+from the new Makefile.in. In some case, you may need to issue the {\bf make} a
+second time. In extreme cases, cd to the top level directory and enter: {\bf
+make Makefiles}.
+
+To add dependencies:
+
+\footnotesize
+\begin{verbatim}
+make depend
+\end{verbatim}
+\normalsize
+
+The {\bf make depend} appends the header file dependencies for each of the
+object files to Makefile and Makefile.in. This command should be done in each
+directory where you change the dependencies. Normally, it only needs to be run
+when you add or delete source or header files. {\bf make depend} is normally
+automatically invoked during the configuration process.
+
+To install:
+
+\footnotesize
+\begin{verbatim}
+make install
+\end{verbatim}
+\normalsize
+
+This not normally done if you are developing Bacula, but is used if you are
+going to run it to backup your system.
+
+After doing a {\bf make install} the following files will be installed on your
+system (more or less). The exact files and location (directory) for each file
+depends on your {\bf ./configure} command (e.g. bgnome-console and
+bgnome-console.conf are not installed if you do not configure GNOME. Also, if
+you are using SQLite instead of MySQL, some of the files will be different).
+
+NOTE: it is quite probable that this list is out of date. But it is a
+starting point.

+\chapter{Messages Resource}
+\label{MessagesChapter}
+\index[general]{Resource!Messages}
+\index[general]{Messages Resource}
+
+The Messages resource defines how messages are to be handled and destinations
+to which they should be sent.
+
+Even though each daemon has a full message handler, within the File daemon and
+the Storage daemon, you will normally choose to send all the appropriate
+messages back to the Director. This permits all the messages associated with a
+single Job to be combined in the Director and sent as a single email message
+to the user, or logged together in a single file.
+
+Each message that Bacula generates (i.e. that each daemon generates) has an
+associated type such as INFO, WARNING, ERROR, FATAL, etc. Using the message
+resource, you can specify which message types you wish to see and where they
+should be sent. In addition, a message may be sent to multiple destinations.
+For example, you may want all error messages both logged as well as sent to
+you in an email. By defining multiple messages resources, you can have
+different message handling for each type of Job (e.g. Full backups versus
+Incremental backups).
+
+In general, messages are attached to a Job and are included in the Job report.
+There are some rare cases, where this is not possible, e.g. when no job is
+running, or if a communications error occurs between a daemon and the
+director. In those cases, the message may remain in the system, and should be
+flushed at the end of the next Job. However, since such messages are not
+attached to a Job, any that are mailed will be sent to {\bf
+/usr/lib/sendmail}. On some systems, such as FreeBSD, if your sendmail is in a
+different place, you may want to link it to the the above location.
+
+The records contained in a Messages resource consist of a {\bf destination}
+specification followed by a list of {\bf message-types} in the format:
+
+\begin{description}
+
+\item [destination = message-type1, message-type2, message-type3, ... ]
+\index[dir]{destination}
+\end{description}
+
+or for those destinations that need and address specification (e.g. email):
+
+\begin{description}
+
+\item [destination = address = message-type1, message-type2,
+ message-type3, ... ]
+\index[dir]{destination}
+
+ Where {\bf destination} is one of a predefined set of keywords that define
+ where the message is to be sent ({\bf stdout}, {\bf file}, ...), {\bf
+ message-type} is one of a predefined set of keywords that define the type of
+ message generated by {\bf Bacula} ({\bf ERROR}, {\bf WARNING}, {\bf FATAL},
+ ...), and {\bf address} varies according to the {\bf destination} keyword, but
+ is typically an email address or a filename.
+\end{description}
+
+The following are the list of the possible record definitions that can be used
+in a message resource.
+
+\begin{description}
+
+\item [Messages]
+\index[dir]{Messages}
+ Start of the Messages records.
+
+\item [Name = \lt{}name\gt{}]
+\index[dir]{Name}
+ The name of the Messages resource. The name you specify here will be used to
+ tie this Messages resource to a Job and/or to the daemon.
+
+\label{mailcommand}
+\item [MailCommand = \lt{}command\gt{}]
+\index[dir]{MailCommand}
+ In the absence of this resource, Bacula will send all mail using the
+ following command:
+
+{\bf mail -s "Bacula Message" \lt{}recipients\gt{}}
+
+In many cases, depending on your machine, this command may not work. Using
+the {\bf MailCommand}, you can specify exactly how to send the mail.
+During the processing of the {\bf command} part, normally specified as a
+quoted string, the following substitutions will be used:
+
+\begin{itemize}
+\item \%\% = \%
+\item \%c = Client's name
+\item \%d = Director's name
+\item \%e = Job Exit code (OK, Error, ...)
+\item \%i = Job Id
+\item \%j = Unique Job name
+\item \%l = Job level
+\item \%n = Job name
+\item \%r = Recipients
+\item \%t = Job type (e.g. Backup, ...)
+\end{itemize}
+
+Please note: any {\bf MailCommand} directive must be specified
+in the {\bf Messages} resource {\bf before} the desired
+{\bf Mail}, {\bf MailOnSuccess}, or {\bf MailOnError}
+directive. In fact, each of those directives may be preceded by
+a different {\bf MailCommand}.
+
+The following is the command I (Kern) use. Note, the whole command should
+appear on a single line in the configuration file rather than split as is
+done here for presentation:
+
+{\bf mailcommand = "/home/kern/bacula/bin/bsmtp -h mail.example.com -f
+\textbackslash{}"\textbackslash{}(Bacula\textbackslash{})
+\%r\textbackslash{}" -s \textbackslash{}"Bacula: \%t \%e of \%c
+\%l\textbackslash{}" \%r"}
+
+The {\bf bsmtp} program is provided as part of {\bf Bacula}. For
+additional details, please see the
+\ilink{ bsmtp -- Customizing Your Email Messages}{bsmtp} section of
+the Bacula Utility Programs chapter of this manual. Please test any {\bf
+mailcommand} that you use to ensure that your bsmtp gateway accepts the
+addressing form that you use. Certain programs such as Exim can be very
+selective as to what forms are permitted particularly in the from part.
+
+\item [OperatorCommand = \lt{}command\gt{}]
+\index[fd]{OperatorCommand}
+ This resource specification is similar to the {\bf MailCommand} except that
+ it is used for Operator messages. The substitutions performed for the {\bf
+ MailCommand} are also done for this command. Normally, you will set this
+ command to the same value as specified for the {\bf MailCommand}.
+ The {\bf OperatorCommand} directive must appear in the {\bf Messages}
+ resource before the {\bf Operator} directive.
+
+\item [\lt{}destination\gt{} = \lt{}message-type1\gt{},
+ \lt{}message-type2\gt{}, ...]
+ \index[fd]{\lt{}destination\gt{}}
+
+Where {\bf destination} may be one of the following:
+
+\begin{description}
+
+\item [stdout]
+ \index[fd]{stdout}
+ Send the message to standard output.
+
+\item [stderr]
+ \index[fd]{stderr}
+ Send the message to standard error.
+
+\item [console]
+ \index[console]{console}
+ Send the message to the console (Bacula Console). These messages are held
+until the console program connects to the Director.
+\end{description}
+
+\item {\bf \lt{}destination\gt{} = \lt{}address\gt{} =
+ \lt{}message-type1\gt{}, \lt{}message-type2\gt{}, ...}
+ \index[console]{\lt{}destination\gt{}}
+
+Where {\bf address} depends on the {\bf destination}.
+
+The {\bf destination} may be one of the following:
+
+\begin{description}
+
+\item [director]
+ \index[dir]{director}
+ \index[general]{director}
+ Send the message to the Director whose name is given in the {\bf address}
+ field. Note, in the current implementation, the Director Name is ignored, and
+ the message is sent to the Director that started the Job.
+
+\item [file]
+\index[dir]{file}
+\index[general]{file}
+ Send the message to the filename given in the {\bf address} field. If the
+ file already exists, it will be overwritten.
+
+\item [append]
+\index[dir]{append}
+\index[general]{append}
+ Append the message to the filename given in the {\bf address} field. If the
+ file already exists, it will be appended to. If the file does not exist, it
+ will be created.
+
+\item [syslog]
+\index[general]{syslog}
+ Send the message to the system log (syslog) using the facility specified in
+ the {\bf address} field. Note, for the moment, the {\bf address} field is
+ ignored and the message is always sent to the LOG\_DAEMON facility with
+ level LOG\_ERR. See {\bf man 3 syslog} for more details. Example:
+\begin{verbatim}
+ syslog = all, !skipped
+\end{verbatim}
+
+\item [mail]
+ \index[general]{mail}
+ Send the message to the email addresses that are given as a comma
+ separated list in the {\bf address} field. Mail messages are grouped
+ together during a job and then sent as a single email message when the
+ job terminates. The advantage of this destination is that you are
+ notified about every Job that runs. However, if you backup five or ten
+ machines every night, the volume of email messages can be important.
+ Some users use filter programs such as {\bf procmail} to automatically
+ file this email based on the Job termination code (see {\bf
+ mailcommand}).
+
+\item [mail on error]
+ \index[general]{mail on error}
+ Send the message to the email addresses that are given as a comma
+ separated list in the {\bf address} field if the Job terminates with an
+ error condition. MailOnError messages are grouped together during a job
+ and then sent as a single email message when the job terminates. This
+ destination differs from the {\bf mail} destination in that if the Job
+ terminates normally, the message is totally discarded (for this
+ destination). If the Job terminates in error, it is emailed. By using
+ other destinations such as {\bf append} you can ensure that even if the
+ Job terminates normally, the output information is saved.
+
+\item [mail on success]
+ \index[general]{mail on success}
+ Send the message to the email addresses that are given as a comma
+ separated list in the {\bf address} field if the Job terminates
+ normally (no error condition). MailOnSuccess messages are grouped
+ together during a job and then sent as a single email message when the
+ job terminates. This destination differs from the {\bf mail}
+ destination in that if the Job terminates abnormally, the message is
+ totally discarded (for this destination). If the Job terminates
+ normally, it is emailed.
+
+\item [operator]
+ \index[general]{operator}
+ Send the message to the email addresses that are specified as a comma
+ separated list in the {\bf address} field. This is similar to {\bf
+ mail} above, except that each message is sent as received. Thus there
+ is one email per message. This is most useful for {\bf mount} messages
+ (see below).
+
+\item [console]
+ \index[general]{console}
+ Send the message to the Bacula console.
+
+\item [stdout]
+ \index[general]{stdout}
+ Send the message to the standard output (normally not used).
+
+\item [stderr]
+ \index[general]{stderr}
+ Send the message to the standard error output (normally not used).
+
+\item [catalog]
+ \index[general]{catalog}
+ Send the message to the Catalog database. The message will be
+ written to the table named {\bf Log} and a timestamp field will
+ also be added. This permits Job Reports and other messages to
+ be recorded in the Catalog so that they can be accessed by
+ reporting software. Bacula will prune the Log records associated
+ with a Job when the Job records are pruned. Otherwise, Bacula
+ never uses these records internally, so this destination is only
+ used for special purpose programs (e.g. {\bf bweb}).
+
+\end{description}
+
+ For any destination, the {\bf message-type} field is a comma separated
+ list of the following types or classes of messages:
+
+\begin{description}
+
+\item [info]
+ \index[general]{info}
+ General information messages.
+
+\item [warning]
+ \index[general]{warning}
+ Warning messages. Generally this is some unusual condition but not expected
+ to be serious.
+
+\item [error]
+ \index[general]{error}
+ Non-fatal error messages. The job continues running. Any error message should
+ be investigated as it means that something went wrong.
+
+\item [fatal]
+ \index[general]{fatal}
+ Fatal error messages. Fatal errors cause the job to terminate.
+
+\item [terminate]
+ \index[general]{terminate}
+ Message generated when the daemon shuts down.
+
+\item [notsaved]
+ \index[fd]{notsaved}
+ \index[general]{notsaved}
+ Files not saved because of some error. Usually because the file cannot be
+ accessed (i.e. it does not exist or is not mounted).
+
+\item [skipped]
+ \index[fd]{skipped}
+ \index[general]{skipped}
+ Files that were skipped because of a user supplied option such as an
+ incremental backup or a file that matches an exclusion pattern. This is
+ not considered an error condition such as the files listed for the {\bf
+ notsaved} type because the configuration file explicitly requests these
+ types of files to be skipped. For example, any unchanged file during an
+ incremental backup, or any subdirectory if the no recursion option is
+ specified.
+
+\item [mount]
+ \index[dir]{mount}
+ \index[general]{mount}
+ Volume mount or intervention requests from the Storage daemon. These
+ requests require a specific operator intervention for the job to
+ continue.
+
+\item [restored]
+ \index[fd]{restored}
+ \index[general]{restored}
+ The {\bf ls} style listing generated for each file restored is sent to
+ this message class.
+
+\item [all]
+ \index[general]{all}
+ All message types.
+
+\item [security]
+ \index[general]{security}
+ Security info/warning messages principally from unauthorized
+ connection attempts.
+
+\item [alert]
+ \index[general]{alert}
+ Alert messages. These are messages generated by tape alerts.
+
+\item [volmgmt]
+ \index[general]{volmgmt}
+ Volume management messages. Currently there are no volume mangement
+ messages generated.
+\end{description}
+
+\end{description}
+
+The following is an example of a valid Messages resource definition, where
+all messages except files explicitly skipped or daemon termination messages
+are sent by email to enforcement@sec.com. In addition all mount messages
+are sent to the operator (i.e. emailed to enforcement@sec.com). Finally
+all messages other than explicitly skipped files and files saved are sent
+to the console:
+
+\footnotesize
+\begin{verbatim}
+Messages {
+ Name = Standard
+ mail = enforcement@sec.com = all, !skipped, !terminate
+ operator = enforcement@sec.com = mount
+ console = all, !skipped, !saved
+}
+\end{verbatim}
+\normalsize
+
+With the exception of the email address (changed to avoid junk mail from
+robot's), an example Director's Messages resource is as follows. Note, the {\bf
+mailcommand} and {\bf operatorcommand} are on a single line -- they had to be
+split for this manual:
+
+\footnotesize
+\begin{verbatim}
+Messages {
+ Name = Standard
+ mailcommand = "bacula/bin/bsmtp -h mail.example.com \
+ -f \"\(Bacula\) %r\" -s \"Bacula: %t %e of %c %l\" %r"
+ operatorcommand = "bacula/bin/bsmtp -h mail.example.com \
+ -f \"\(Bacula\) %r\" -s \"Bacula: Intervention needed \
+ for %j\" %r"
+ MailOnError = security@example.com = all, !skipped, \
+ !terminate
+ append = "bacula/bin/log" = all, !skipped, !terminate
+ operator = security@example.com = mount
+ console = all, !skipped, !saved
+}

+\chapter{Monitor Configuration}
+\label{_MonitorChapter}
+\index[general]{Monitor Configuration }
+\index[general]{Configuration!Monitor }
+
+The Monitor configuration file is a stripped down version of the Director
+configuration file, mixed with a Console configuration file. It simply
+contains the information necessary to contact Directors, Clients, and Storage
+daemons you want to monitor.
+
+For a general discussion of configuration file and resources including the
+data types recognized by {\bf Bacula}, please see the
+\ilink{Configuration}{ConfigureChapter} chapter of this manual.
+
+The following Monitor Resource definition must be defined:
+
+\begin{itemize}
+\item
+ \ilink{Monitor}{MonitorResource} -- to define the Monitor's
+ name used to connect to all the daemons and the password used to connect to
+the Directors. Note, you must not define more than one Monitor resource in
+the Monitor configuration file.
+\item At least one
+ \ilink{Client}{ClientResource1},
+ \ilink{Storage}{StorageResource1} or
+\ilink{Director}{DirectorResource2} resource, to define the
+daemons to monitor.
+\end{itemize}
+
+\section{The Monitor Resource}
+\label{MonitorResource}
+\index[general]{Monitor Resource }
+\index[general]{Resource!Monitor }
+
+The Monitor resource defines the attributes of the Monitor running on the
+network. The parameters you define here must be configured as a Director
+resource in Clients and Storages configuration files, and as a Console
+resource in Directors configuration files.
+
+\begin{description}
+
+\item [Monitor]
+ \index[fd]{Monitor }
+ Start of the Monitor records.
+
+\item [Name = \lt{}name\gt{}]
+ \index[fd]{Name }
+ Specify the Director name used to connect to Client and Storage, and the
+Console name used to connect to Director. This record is required.
+
+\item [Password = \lt{}password\gt{}]
+ \index[fd]{Password }
+ Where the password is the password needed for Directors to accept the Console
+connection. This password must be identical to the {\bf Password} specified
+in the {\bf Console} resource of the
+\ilink{Director's configuration}{DirectorChapter} file. This
+record is required if you wish to monitor Directors.
+
+\item [Refresh Interval = \lt{}time\gt{}]
+ \index[fd]{Refresh Interval }
+ Specifies the time to wait between status requests to each daemon. It can't
+be set to less than 1 second, or more than 10 minutes, and the default value
+is 5 seconds.
+% TODO: what is format of the time?
+% TODO: should the digits in this definition be spelled out? should
+% TODO: this say "time-period-specification" above??)
+\end{description}
+
+\section{The Director Resource}
+\label{DirectorResource2}
+\index[general]{Director Resource }
+\index[general]{Resource!Director }
+
+The Director resource defines the attributes of the Directors that are
+monitored by this Monitor.
+
+As you are not permitted to define a Password in this resource, to avoid
+obtaining full Director privileges, you must create a Console resource in the
+\ilink{Director's configuration}{DirectorChapter} file, using the
+Console Name and Password defined in the Monitor resource. To avoid security
+problems, you should configure this Console resource to allow access to no
+other daemons, and permit the use of only two commands: {\bf status} and {\bf
+.status} (see below for an example).
+
+You may have multiple Director resource specifications in a single Monitor
+configuration file.
+
+\begin{description}
+
+\item [Director]
+ \index[fd]{Director }
+ Start of the Director records.
+
+\item [Name = \lt{}name\gt{}]
+ \index[fd]{Name }
+ The Director name used to identify the Director in the list of monitored
+daemons. It is not required to be the same as the one defined in the Director's
+configuration file. This record is required.
+
+\item [DIRPort = \lt{}port-number\gt{}]
+ \index[fd]{DIRPort }
+ Specify the port to use to connect to the Director. This value will most
+likely already be set to the value you specified on the {\bf
+\verb:--:with-base-port} option of the {\bf ./configure} command. This port must be
+identical to the {\bf DIRport} specified in the {\bf Director} resource of
+the
+\ilink{Director's configuration}{DirectorChapter} file. The
+default is 9101 so this record is not normally specified.
+
+\item [Address = \lt{}address\gt{}]
+ \index[fd]{Address }
+ Where the address is a host name, a fully qualified domain name, or a network
+address used to connect to the Director. This record is required.
+\end{description}
+
+\section{The Client Resource}
+\label{ClientResource1}
+\index[general]{Resource!Client }
+\index[general]{Client Resource }
+
+The Client resource defines the attributes of the Clients that are monitored
+by this Monitor.
+
+You must create a Director resource in the
+\ilink{Client's configuration}{FiledConfChapter} file, using the
+Director Name defined in the Monitor resource. To avoid security problems, you
+should set the {\bf Monitor} directive to {\bf Yes} in this Director resource.
+
+
+You may have multiple Director resource specifications in a single Monitor
+configuration file.
+
+\begin{description}
+
+\item [Client (or FileDaemon)]
+ \index[fd]{Client (or FileDaemon) }
+ Start of the Client records.
+
+\item [Name = \lt{}name\gt{}]
+ \index[fd]{Name }
+ The Client name used to identify the Director in the list of monitored
+daemons. It is not required to be the same as the one defined in the Client's
+configuration file. This record is required.
+
+\item [Address = \lt{}address\gt{}]
+ \index[fd]{Address }
+ Where the address is a host name, a fully qualified domain name, or a network
+address in dotted quad notation for a Bacula File daemon. This record is
+required.
+
+\item [FD Port = \lt{}port-number\gt{}]
+ \index[fd]{FD Port }
+ Where the port is a port number at which the Bacula File daemon can be
+contacted. The default is 9102.
+
+\item [Password = \lt{}password\gt{}]
+ \index[fd]{Password }
+ This is the password to be used when establishing a connection with the File
+services, so the Client configuration file on the machine to be backed up
+must have the same password defined for this Director. This record is
+required.

+\section{The Storage Resource}
+\label{StorageResource1}
+\index[general]{Resource!Storage }
+\index[general]{Storage Resource }
+
+The Storage resource defines the attributes of the Storages that are monitored
+by this Monitor.
+
+You must create a Director resource in the
+\ilink{Storage's configuration}{StoredConfChapter} file, using the
+Director Name defined in the Monitor resource. To avoid security problems, you
+should set the {\bf Monitor} directive to {\bf Yes} in this Director resource.
+
+
+You may have multiple Director resource specifications in a single Monitor
+configuration file.
+
+\begin{description}
+
+\item [Storage]
+ \index[fd]{Storage }
+ Start of the Storage records.
+
+\item [Name = \lt{}name\gt{}]
+ \index[fd]{Name }
+ The Storage name used to identify the Director in the list of monitored
+daemons. It is not required to be the same as the one defined in the Storage's
+configuration file. This record is required.
+
+\item [Address = \lt{}address\gt{}]
+ \index[fd]{Address }
+ Where the address is a host name, a fully qualified domain name, or a network
+address in dotted quad notation for a Bacula Storage daemon. This record is
+required.
+
+\item [SD Port = \lt{}port\gt{}]
+ \index[fd]{SD Port }
+ Where port is the port to use to contact the storage daemon for information
+and to start jobs. This same port number must appear in the Storage resource
+of the Storage daemon's configuration file. The default is 9103.
+
+\item [Password = \lt{}password\gt{}]
+ \index[sd]{Password }
+ This is the password to be used when establishing a connection with the
+Storage services. This same password also must appear in the Director
+resource of the Storage daemon's configuration file. This record is required.
+
+\end{description}
+
+\section{Tray Monitor Security}
+\index[general]{Tray Monitor Security}
+
+There is no security problem in relaxing the permissions on
+tray-monitor.conf as long as FD, SD and DIR are configured properly, so
+the passwords contained in this file only gives access to the status of
+the daemons. It could be a security problem if you consider the status
+information as potentially dangerous (I don't think it is the case).
+
+Concerning Director's configuration: \\
+In tray-monitor.conf, the password in the Monitor resource must point to
+a restricted console in bacula-dir.conf (see the documentation). So, if
+you use this password with bconsole, you'll only have access to the
+status of the director (commands status and .status).
+It could be a security problem if there is a bug in the ACL code of the
+director.
+
+Concerning File and Storage Daemons' configuration:\\
+In tray-monitor.conf, the Name in the Monitor resource must point to a
+Director resource in bacula-fd/sd.conf, with the Monitor directive set
+to Yes (once again, see the documentation).
+It could be a security problem if there is a bug in the code which check
+if a command is valid for a Monitor (this is very unlikely as the code
+is pretty simple).

+\chapter{Getting Started with Bacula}
+\label{QuickStartChapter}
+\index[general]{Getting Started with Bacula }
+
+If you are like me, you want to get Bacula running immediately to get a feel
+for it, then later you want to go back and read about all the details. This
+chapter attempts to accomplish just that: get you going quickly without all
+the details. If you want to skip the section on Pools, Volumes and Labels, you
+can always come back to it, but please read to the end of this chapter, and in
+particular follow the instructions for testing your tape drive.
+
+We assume that you have managed to build and install Bacula, if not, you might
+want to first look at the
+\ilink{System Requirements}{SysReqs} then at the
+\ilink{Compiling and Installing Bacula}{InstallChapter} chapter of
+this manual.
+
+\label{JobsandSchedules}
+\section{Understanding Jobs and Schedules}
+\index[general]{Jobs!Understanding}
+\index[general]{Schedules!Understanding}
+
+In order to make Bacula as flexible as possible, the directions given
+to Bacula are specified in several pieces. The main instruction is the
+job resource, which defines a job. A backup job generally consists of a
+FileSet, a Client, a Schedule for one or several levels or times of backups,
+a Pool, as well as additional instructions. Another way of looking
+at it is the FileSet is what to backup; the Client is who to backup; the
+Schedule defines when, and the Pool defines where (i.e. what Volume).
+
+Typically one FileSet/Client combination will have one corresponding job.
+Most of the directives, such as FileSets, Pools, Schedules, can be mixed
+and matched among the jobs. So you might have two different Job
+definitions (resources) backing up different servers using the same
+Schedule, the same Fileset (backing up the same directories on two machines)
+and maybe even the same Pools. The Schedule will define what type of
+backup will run when (e.g. Full on Monday, incremental the rest of the
+week), and when more than one job uses the same schedule, the job priority
+determines which actually runs first. If you have a lot of jobs, you might
+want to use JobDefs, where you can set defaults for the jobs, which can
+then be changed in the job resource, but this saves rewriting the
+identical parameters for each job. In addition to the FileSets you want to
+back up, you should also have a job that backs up your catalog.
+
+Finally, be aware that in addition to the backup jobs there are
+restore, verify, and admin jobs, which have different requirements.
+
+\label{PoolsVolsLabels}
+\section{Understanding Pools, Volumes and Labels}
+\index[general]{Labels!Understanding Pools Volumes and }
+\index[general]{Understanding Pools, Volumes and Labels }
+
+If you have been using a program such as {\bf tar} to backup your system,
+Pools, Volumes, and labeling may be a bit confusing at first. A Volume is a
+single physical tape (or possibly a single file) on which Bacula will write
+your backup data. Pools group together Volumes so that a backup is not
+restricted to the length of a single Volume (tape). Consequently, rather than
+explicitly naming Volumes in your Job, you specify a Pool, and Bacula will
+select the next appendable Volume from the Pool and request you to mount it.
+% TODO: can't it mount it itself if already available?
+
+Although the basic Pool options are specified in the Director's Pool resource,
+the {\bf real} Pool is maintained in the Bacula Catalog. It contains
+information taken from the Pool resource (bacula-dir.conf) as well as
+information on all the Volumes that have been added to the Pool. Adding
+Volumes to a Pool is usually done manually with the Console program using the
+{\bf label} command.
+
+For each Volume, Bacula maintains a fair amount of catalog information such as
+the first write date/time, the last write date/time, the number of files on
+the Volume, the number of bytes on the Volume, the number of Mounts, etc.
+
+Before Bacula will read or write a Volume, the physical Volume must have a
+Bacula software label so that Bacula can be sure the correct Volume is
+mounted. This is usually done using the {\bf label} command in the Console
+program.
+
+The steps for creating a Pool, adding Volumes to it, and writing software
+labels to the Volumes, may seem tedious at first, but in fact, they are quite
+simple to do, and they allow you to use multiple Volumes (rather than being
+limited to the size of a single tape). Pools also give you significant
+flexibility in your backup process. For example, you can have a "Daily" Pool
+of Volumes for Incremental backups and a "Weekly" Pool of Volumes for Full
+backups. By specifying the appropriate Pool in the daily and weekly backup
+Jobs, you thereby insure that no daily Job ever writes to a Volume in the
+Weekly Pool and vice versa, and Bacula will tell you what tape is needed and
+when.
+
+For more on Pools, see the
+\ilink{Pool Resource}{PoolResource} section of the Director
+Configuration chapter, or simply read on, and we will come back to this
+subject later.
+
+\section{Setting Up Bacula Configuration Files}
+\label{config}
+\index[general]{Setting Up Bacula Configuration Files }
+\index[general]{Files!Setting Up Bacula Configuration }
+
+% TODO: this assumes installation from source:
+After running the appropriate {\bf ./configure} command and doing
+a {\bf make}, and a {\bf make install}, if this is the first time
+you are running Bacula, you must create valid configuration files
+for the Director, the File daemon, the Storage daemon, and the
+Console programs. If you have followed our recommendations,
+default configuration files as well as the daemon binaries will
+be located in your installation directory. In any case, the
+binaries are found in the directory you specified on the {\bf
+\verb:--:sbindir} option to the {\bf ./configure} command, and
+the configuration files are found in the directory you specified
+on the {\bf \verb:--:sysconfdir} option.
+
+When initially setting up Bacula you will need to invest a bit of time in
+modifying the default configuration files to suit your environment. This may
+entail starting and stopping Bacula a number of times until you get everything
+right. Please do not despair. Once you have created your configuration files,
+you will rarely need to change them nor will you stop and start Bacula very
+often. Most of the work will simply be in changing the tape when it is full.
+
+\subsection{Configuring the Console Program}
+\index[general]{Configuring the Console Program }
+\index[general]{Program!Configuring the Console }
+
+The Console program is used by the administrator to interact with the Director
+and to manually start/stop Jobs or to obtain Job status information.
+
+The Console configuration file is found in the directory specified on the
+{\bf \verb:--:sysconfdir} option that you specified on the {\bf
+./configure} command and by default is named {\bf bconsole.conf}.
+
+If you choose to build the GNOME console with the {\bf
+\verb:--:enable-gnome} option, you also find a default configuration file
+for it, named {\bf bgnome-console.conf}.
+
+The same applies to the wxWidgets console, which is build with the {\bf
+\verb:--:enable-bwx-console} option, and the name of the default
+configuration file is, in this case, {\bf bwx-console.conf}.
+
+Normally, for first time users, no change is needed to these files. Reasonable
+defaults are set.
+
+Further details are in the
+\ilink{Console configuration}{ConsoleConfChapter} chapter.
+
+\subsection{Configuring the Monitor Program}
+\index[general]{Program!Configuring the Monitor }
+\index[general]{Configuring the Monitor Program }
+
+The Monitor program is typically an icon in the system tray. However, once the
+icon is expanded into a full window, the administrator or user can obtain
+status information about the Director or the backup status on the local
+workstation or any other Bacula daemon that is configured.
+
+\addcontentsline{lof}{figure}{Bacula Tray Monitor}
+\includegraphics{\idir Bacula-tray-monitor.eps}
+
+% TODO: image may be too wide for 6" wide printed page.
+The image shows a tray-monitor configured for three daemons. By clicking on
+the radio buttons in the upper left corner of the image, you can see the
+status for each of the daemons. The image shows the status for the Storage
+daemon (MainSD) that is currently selected.
+
+The Monitor configuration file is found in the directory specified on the {\bf
+\verb:--:sysconfdir} option that you specified on the {\bf ./configure} command
+and
+by default is named {\bf tray-monitor.conf}. Normally, for first time users,
+you just need to change the permission of this file to allow non-root users to
+run the Monitor, as this application must run as the same user as the
+graphical environment (don't forget to allow non-root users to execute {\bf
+bacula-tray-monitor}). This is not a security problem as long as you use the
+default settings.
+
+More information is in the
+\ilink{Monitor configuration}{_MonitorChapter} chapter.
+
+\subsection{Configuring the File daemon}
+\index[general]{Daemon!Configuring the File }
+\index[general]{Configuring the File daemon }
+
+The File daemon is a program that runs on each (Client) machine. At the
+request of the Director, finds the files to be backed up and sends them (their
+data) to the Storage daemon.
+
+The File daemon configuration file is found in the directory specified on
+the {\bf \verb:--:sysconfdir} option that you specified on the {\bf ./configure}
+command. By default, the File daemon's configuration file is named {\bf
+bacula-fd.conf}. Normally, for first time users, no change is needed to this
+file. Reasonable defaults are set. However, if you are going to back up more
+than one machine, you will need to install the File daemon with a unique
+configuration file on each machine to be backed up. The information about each
+File daemon must appear in the Director's configuration file.
+% TODO: point to section about how to install just the File daemon
+% TODO: and creating the unique configuration file.
+
+Further details are in the
+\ilink{File daemon configuration}{FiledConfChapter} chapter.
+
+\subsection{Configuring the Director}
+\index[general]{Director!Configuring the }
+\index[general]{Configuring the Director }
+
+The Director is the central control program for all the other daemons. It
+schedules and monitors all jobs to be backed up.
+
+The Director configuration file is found in the directory specified on the
+{\bf \verb:--:sysconfdir} option that you specified on the {\bf ./configure}
+command. Normally the Director's configuration file is named {\bf bacula-dir.conf}.
+
+In general, the only change you must make is modify the FileSet resource so
+that the {\bf Include} configuration directive contains at least one line with
+a valid name of a directory (or file) to be saved.
+
+% TODO: is DLT still the default config?
+If you do not have a DLT tape drive, you will probably want to edit the
+Storage resource to contain names that are more representative of your actual
+storage device. You can always use the existing names as you are free to
+arbitrarily assign them, but they must agree with the corresponding names in
+the Storage daemon's configuration file.
+
+You may also want to change the email address for notification from the
+default {\bf root} to your email address.
+
+Finally, if you have multiple systems to be backed up, you will need a
+separate File daemon or Client specification for each system, specifying its
+% TODO: I don't see any example "File" configuraton in the default
+% TODO: bacula-dir.conf; I do see FileDaemon config in the default

+% TODO: about this.
+name, address, and password. We have found that giving your daemons the same
+% TODO: what passwords should I use? I have different ones in the
+% TODO: different configs on different systems. Point to explanation of
+% this.
+name as your system but post fixed with {\bf -fd} helps a lot in debugging.
+That is, if your system name is {\bf foobaz}, you would give the File daemon
+the name {\bf foobaz-fd}. For the Director, you should use {\bf foobaz-dir},
+and for the storage daemon, you might use {\bf foobaz-sd}.
+Each of your Bacula components {\bf must} have a unique name. If you
+make them all the same, aside from the fact that you will not
+know what daemon is sending what message, if they share the same
+working directory, the daemons temporary file names will not
+be unique, and you will get many strange failures.
+% TODO: why not check for that and not allow sharing working directory?
+
+More information is in the
+\ilink{Director configuration}{DirectorChapter} chapter.
+
+\subsection{Configuring the Storage daemon}
+\index[general]{Daemon!Configuring the Storage }
+\index[general]{Configuring the Storage daemon }
+
+The Storage daemon is responsible, at the Director's request, for accepting
+data from a File daemon and placing it on Storage media, or in the case of a
+restore request, to find the data and send it to the File daemon.
+
+The Storage daemon's configuration file is found in the directory specified on
+the {\bf \verb:--:sysconfdir} option that you specified on the {\bf ./configure}
+command. By default, the Storage daemon's file is named {\bf bacula-sd.conf}.
+Edit this file to contain the correct Archive device names for any tape
+devices that you have. If the configuration process properly detected your
+system, they will already be correctly set. These Storage resource name and
+Media Type must be the same as the corresponding ones in the Director's
+configuration file {\bf bacula-dir.conf}. If you want to backup to a file
+instead of a tape, the Archive device must point to a directory in which the
+Volumes will be created as files when you label the Volume.
+\label{ConfigTesting}
+
+Further information is in the
+\ilink{Storage daemon configuration}{StoredConfChapter} chapter.
+
+\section{Testing your Configuration Files}
+\index[general]{Testing your Configuration Files }
+\index[general]{Files!Testing your Configuration }
+
+You can test if your configuration file is syntactically correct by running
+the appropriate daemon with the {\bf -t} option. The daemon will process the
+configuration file and print any error messages then terminate. For example,
+assuming you have installed your binaries and configuration files in the same
+directory.
+% TODO: why assume that? common default install has the executable

+configuration file is OK, the program will terminate without printing
+anything. Please note that, depending on the configure options you choose,
+some, or even all, of the three last commands will not be available on your
+system. If you have installed the binaries in traditional Unix locations
+rather than a single file, you will need to modify the above commands
+appropriately (no ./ in front of the command name, and a path in front of the
+conf file name).

+\section{Testing Compatibility with Your Tape Drive}
+\index[general]{Drive!Testing Bacula Compatibility with Your Tape}
+\index[general]{Testing Bacula Compatibility with Your Tape Drive}
+
+Before spending a lot of time on Bacula only to find that it doesn't work
+with your tape drive, please read the {\bf Testing Your Tape
+Drive} chapter of this manual. If you have a modern
+standard SCSI tape drive on a Linux or Solaris, most likely it will work,
+but better test than be sorry. For FreeBSD (and probably other xBSD
+flavors), reading the above mentioned tape testing chapter is a must.
+Also, for FreeBSD, please see \elink{The FreeBSD
+Diary}{\url{http://www.freebsddiary.org/bacula.php}} for a detailed description
+%TODO: fix elink so it shows URL in PDF
+on how to make Bacula work on your system. In addition, users of FreeBSD

+\index[general]{Directory!Get Rid of the /lib/tls }
+\index[general]{Get Rid of the /lib/tls Directory }
+The new pthreads library {\bf /lib/tls} installed by default on recent Red
+Hat systems running Linux kernel 2.4.x is defective. You must remove it or
+rename it, then reboot your system before running Bacula otherwise after a
+week or so of running, Bacula will either block for long periods or
+deadlock entirely. You may want to use the loader environment variable
+override rather than removing /lib/tls. Please see \ilink{ Supported
+Operating Systems}{SupportedOSes} for more information on this problem.
+
+This problem does not occur on systems running Linux 2.6.x kernels.

+
+\section{Running Bacula}
+\index[general]{Bacula!Running }
+\index[general]{Running Bacula }
+
+Probably the most important part of running Bacula is being able to restore
+files. If you haven't tried recovering files at least once, when you actually
+have to do it, you will be under a lot more pressure, and prone to make
+errors, than if you had already tried it once.
+
+To get a good idea how to use Bacula in a short time, we {\bf strongly}
+recommend that you follow the example in the
+\ilink{Running Bacula Chapter}{TutorialChapter} of this manual where
+you will get detailed instructions on how to run Bacula.
+
+\section{Log Rotation}
+\index[general]{Rotation!Log }
+\index[general]{Log Rotation }
+If you use the default {\bf bacula-dir.conf} or some variation of it, you will
+note that it logs all the Bacula output to a file. To avoid that this file
+grows without limit, we recommend that you copy the file {\bf logrotate} from
+the {\bf scripts/logrotate} to {\bf /etc/logrotate.d/bacula}. This will cause
+the log file to be rotated once a month and kept for a maximum of five months.
+You may want to edit this file to change the default log rotation preferences.
+
+\section{Log Watch}
+\index[general]{Watch!Log}
+\index[general]{Log Watch}
+Some systems such as Red Hat and Fedora run the logwatch program

+\index[general]{Disaster Recovery }
+
+If you intend to use Bacula as a disaster recovery tool rather than simply a

+\ilink{Disaster Recovery Using Bacula Chapter}{RescueChapter} of
+this manual.
+
+In any case, you are strongly urged to carefully test restoring some files

+\chapter{Bacula Security Issues}
+\label{SecurityChapter}
+\index[general]{Bacula Security Issues}
+\index[general]{Security}
+\index[general]{Issues!Bacula Security}
+
+\begin{itemize}
+\item Security means being able to restore your files, so read the
+ \ilink{Critical Items Chapter}{Critical} of this manual.
+\item The Clients ({\bf bacula-fd}) must run as root to be able to access all
+ the system files.
+\item It is not necessary to run the Director as root.
+\item It is not necessary to run the Storage daemon as root, but you must
+ ensure that it can open the tape drives, which are often restricted to root
+ access by default. In addition, if you do not run the Storage daemon as root,
+ it will not be able to automatically set your tape drive parameters on most
+ OSes since these functions, unfortunately require root access.
+\item You should restrict access to the Bacula configuration files, so that
+ the passwords are not world-readable. The {\bf Bacula} daemons are password
+ protected using CRAM-MD5 (i.e. the password is not sent across the network).
+ This will ensure that not everyone can access the daemons. It is a reasonably
+ good protection, but can be cracked by experts.
+\item If you are using the recommended ports 9101, 9102, and 9103, you will
+ probably want to protect these ports from external access using a firewall
+ and/or using tcp wrappers ({\bf etc/hosts.allow}).
+\item By default, all data that is sent across the network is unencrypted.
+ However, Bacula does support TLS (transport layer security) and can
+ encrypt transmitted data. Please read the
+ \ilink{TLS (SSL) Communications Encryption}{CommEncryption}
+ section of this manual.
+\item You should ensure that the Bacula working directories are readable and
+ writable only by the Bacula daemons.
+\item If you are using {\bf MySQL} it is not necessary for it to run with
+ {\bf root} permission.
+\item The default Bacula {\bf grant-mysql-permissions} script grants all
+ permissions to use the MySQL database without a password. If you want
+ security, please tighten this up!
+\item Don't forget that Bacula is a network program, so anyone anywhere on
+ the network with the console program and the Director's password can access
+ Bacula and the backed up data.
+\item You can restrict what IP addresses Bacula will bind to by using the
+ appropriate {\bf DirAddress}, {\bf FDAddress}, or {\bf SDAddress} records in
+ the respective daemon configuration files.
+\item Be aware that if you are backing up your database using the default
+ script, if you have a password on your database, it will be passed as
+ a command line option to that script, and any user will be able to see
+ this information. If you want it to be secure, you will need to pass it
+ by an environment variable or a secure file.
+
+ See also \ilink{Backing Up Your Bacula
+ Database - Security Considerations }{BackingUpBaculaSecurityConsiderations}
+ for more information.
+\end{itemize}
+
+
+\section{Backward Compatibility}
+\index[general]{Backward Compatibility}
+One of the major goals of Bacula is to ensure that you can restore
+tapes (I'll use the word tape to include disk Volumes) that you wrote years
+ago. This means that each new version of Bacula should be able to read old
+format tapes. The first problem you will have is to ensure that the
+hardware is still working some years down the road, and the second
+problem will be to ensure that the media will still be good, then
+your OS must be able to interface to the device, and finally Bacula
+must be able to recognize old formats. All the problems except the
+last are ones that we cannot solve, but by careful planning you can.
+
+Since the very beginning of Bacula (January 2000) until today (December
+2005), there have been two major Bacula tape formats. The second format
+was introduced in version 1.27 in November of 2002, and it has not
+changed since then. In principle, Bacula can still read the original
+format, but I haven't tried it lately so who knows ...
+
+Though the tape format is fixed, the kinds of data that we can put on the
+tapes are extensible, and that is how we added new features
+such as ACLs, Win32 data, encrypted data, ... Obviously, an older
+version of Bacula would not know how to read these newer data streams,
+but each newer version of Bacula should know how to read all the
+older streams.
+
+If you want to be 100% sure that you can read old tapes, you
+should:
+
+1. Try reading old tapes from time to time -- e.g. at least once
+a year.
+
+2. Keep statically linked copies of every version of Bacula that you use
+in production then if for some reason, we botch up old tape compatibility, you
+can always pull out an old copy of Bacula ...
+
+The second point is probably overkill but if you want to be sure, it may
+save you someday.

+\section{Configuring and Testing TCP Wrappers}
+\index[general]{Configuring and Testing TCP Wrappers}
+\index[general]{TCP Wrappers}
+\index[general]{Wrappers!TCP}
+\index[general]{libwrappers}
+
+TCP Wrappers are implemented if you turn them on when configuring
+({\bf ./configure \verb:--:with-tcp-wrappers}).
+With this code enabled, you may control who may access your
+daemons. This control is done by modifying the file: {\bf
+/etc/hosts.allow}. The program name that {\bf Bacula} uses when
+applying these access restrictions is the name you specify in the
+daemon configuration file (see below for examples).
+You must not use the {\bf twist} option in your {\bf
+/etc/hosts.allow} or it will terminate the Bacula daemon when a
+connection is refused.
+
+The exact name of the package you need loaded to build with TCP wrappers
+depends on the system. For example,
+on SuSE, the TCP wrappers libraries needed to link Bacula are
+contained in the tcpd-devel package. On Red Hat, the package is named
+tcp\_wrappers.
+
+Dan Langille has provided the following information on configuring and
+testing TCP wrappers with Bacula.
+
+If you read hosts\_options(5), you will see an option called twist. This
+option replaces the current process by an instance of the specified shell
+command. Typically, something like this is used:
+
+\footnotesize
+\begin{verbatim}
+ALL : ALL \
+ : severity auth.info \
+ : twist /bin/echo "You are not welcome to use %d from %h."
+\end{verbatim}
+\normalsize
+
+The libwrap code tries to avoid {\bf twist} if it runs in a resident process,
+but that test will not protect the first hosts\_access() call. This will
+result in the process (e.g. bacula-fd, bacula-sd, bacula-dir) being terminated
+if the first connection to their port results in the twist option being
+invoked. The potential, and I stress potential, exists for an attacker to
+prevent the daemons from running. This situation is eliminated if your
+/etc/hosts.allow file contains an appropriate rule set. The following example
+is sufficient:
+
+\footnotesize
+\begin{verbatim}
+undef-fd : localhost : allow
+undef-sd : localhost : allow
+undef-dir : localhost : allow
+undef-fd : ALL : deny
+undef-sd : ALL : deny
+undef-dir : ALL : deny
+\end{verbatim}
+\normalsize
+
+You must adjust the names to be the same as the Name directives found
+in each of the daemon configuration files. They are, in general, not the
+same as the binary daemon names. It is not possible to use the
+daemon names because multiple daemons may be running on the same machine
+but with different configurations.
+
+In these examples, the Director is undef-dir, the
+Storage Daemon is undef-sd, and the File Daemon is undef-fd. Adjust to suit
+your situation. The above example rules assume that the SD, FD, and DIR all
+reside on the same box. If you have a remote FD client, then the following
+rule set on the remote client will suffice:
+
+\footnotesize
+\begin{verbatim}
+undef-fd : director.example.org : allow
+undef-fd : ALL : deny
+\end{verbatim}
+\normalsize
+
+where director.example.org is the host which will be contacting the client
+(ie. the box on which the Bacula Director daemon runs). The use of "ALL :
+deny" ensures that the twist option (if present) is not invoked. To properly
+test your configuration, start the daemon(s), then attempt to connect from an
+IP address which should be able to connect. You should see something like
+this:
+
+\footnotesize
+\begin{verbatim}
+$ telnet undef 9103
+Trying 192.168.0.56...
+Connected to undef.example.org.
+Escape character is '^]'.
+Connection closed by foreign host.
+$
+\end{verbatim}
+\normalsize
+
+This is the correct response. If you see this:
+
+\footnotesize
+\begin{verbatim}
+$ telnet undef 9103
+Trying 192.168.0.56...
+Connected to undef.example.org.
+Escape character is '^]'.
+You are not welcome to use undef-sd from xeon.example.org.
+Connection closed by foreign host.
+$
+\end{verbatim}
+\normalsize
+
+then twist has been invoked and your configuration is not correct and you need
+to add the deny statement. It is important to note that your testing must
+include restarting the daemons after each connection attempt. You can also
+tcpdchk(8) and tcpdmatch(8) to validate your /etc/hosts.allow rules. Here is a
+simple test using tcpdmatch:
+
+\footnotesize
+\begin{verbatim}
+$ tcpdmatch undef-dir xeon.example.org
+warning: undef-dir: no such process name in /etc/inetd.conf
+client: hostname xeon.example.org
+client: address 192.168.0.18
+server: process undef-dir
+matched: /etc/hosts.allow line 40
+option: allow
+access: granted
+\end{verbatim}
+\normalsize
+
+If you are running Bacula as a standalone daemon, the warning above can be
+safely ignored. Here is an example which indicates that your rules are missing
+a deny statement and the twist option has been invoked.
+
+\footnotesize
+\begin{verbatim}
+$ tcpdmatch undef-dir 10.0.0.1
+warning: undef-dir: no such process name in /etc/inetd.conf
+client: address 10.0.0.1
+server: process undef-dir
+matched: /etc/hosts.allow line 91
+option: severity auth.info
+option: twist /bin/echo "You are not welcome to use
+ undef-dir from 10.0.0.1."
+access: delegated
+\end{verbatim}
+\normalsize
+
+\section{Running as non-root}
+\index[general]{Running as non-root }
+
+Security advice from Dan Langille:
+% TODO: don't use specific name
+
+% TODO: don't be too specific on operating system
+
+% TODO: maybe remove personalization?
+
+It is a good idea to run daemons with the lowest possible privileges. In
+other words, if you can, don't run applications as root which do not have to
+be root. The Storage Daemon and the Director Daemon do not need to be root.
+The File Daemon needs to be root in order to access all files on your system.
+In order to run as non-root, you need to create a user and a group. Choosing
+{\tt bacula} as both the user name and the group name sounds like a good idea
+to me.
+
+The FreeBSD port creates this user and group for you.
+Here is what those entries looked like on my FreeBSD laptop:
+
+\footnotesize
+\begin{verbatim}
+bacula:*:1002:1002::0:0:Bacula Daemon:/var/db/bacula:/sbin/nologin
+\end{verbatim}
+\normalsize
+
+I used vipw to create this entry. I selected a User ID and Group ID of 1002
+as they were unused on my system.
+
+I also created a group in /etc/group:
+
+\footnotesize
+\begin{verbatim}
+bacula:*:1002:
+\end{verbatim}
+\normalsize
+
+The bacula user (as opposed to the Bacula daemon) will have a home directory
+of {\tt /var/db/bacula} which is the default location for the Bacula
+database.
+
+Now that you have both a bacula user and a bacula group, you can secure the
+bacula home directory by issuing this command:
+
+\footnotesize
+\begin{verbatim}
+chown -R bacula:bacula /var/db/bacula/
+\end{verbatim}
+\normalsize
+
+This ensures that only the bacula user can access this directory. It also
+means that if we run the Director and the Storage daemon as bacula, those
+daemons also have restricted access. This would not be the case if they were
+running as root.
+
+It is important to note that the storage daemon actually needs to be in the
+operator group for normal access to tape drives etc (at least on a FreeBSD
+system, that's how things are set up by default) Such devices are normally
+chown root:operator. It is easier and less error prone to make Bacula a
+member of that group than it is to play around with system permissions.
+
+Starting the Bacula daemons
+
+To start the bacula daemons on a FreeBSD system, issue the following command:
+
+\footnotesize
+\begin{verbatim}
+/usr/local/etc/rc.d/bacula-dir start
+/usr/local/etc/rc.d/bacula-sd start
+/usr/local/etc/rc.d/bacula-fd start
+\end{verbatim}
+\normalsize
+
+To confirm they are all running:
+
+\footnotesize
+\begin{verbatim}
+$ ps auwx | grep bacula
+root 63418 0.0 0.3 1856 1036 ?? Ss 4:09PM 0:00.00

+\chapter{Storage Daemon Configuration}
+\label{StoredConfChapter}
+\index[general]{Storage Daemon Configuration}
+\index[general]{Configuration!Storage Daemon}
+
+The Storage Daemon configuration file has relatively few resource definitions.
+However, due to the great variation in backup media and system capabilities,
+the storage daemon must be highly configurable. As a consequence, there are
+quite a large number of directives in the Device Resource definition that
+allow you to define all the characteristics of your Storage device (normally a
+tape drive). Fortunately, with modern storage devices, the defaults are
+sufficient, and very few directives are actually needed.
+
+Examples of {\bf Device} resource directives that are known to work for a
+number of common tape drives can be found in the {\bf
+\lt{}bacula-src\gt{}/examples/devices} directory, and most will also be listed
+here.
+
+For a general discussion of configuration file and resources including the
+data types recognized by {\bf Bacula}, please see the
+\ilink{Configuration}{ConfigureChapter} chapter of this manual. The
+following Storage Resource definitions must be defined:
+
+\begin{itemize}
+\item
+ \ilink{Storage}{StorageResource} -- to define the name of the
+ Storage daemon.
+\item
+ \ilink{Director}{DirectorResource1} -- to define the Director's
+ name and his access password.
+\item
+ \ilink{Device}{DeviceResource} -- to define the
+ characteristics of your storage device (tape drive).
+\item
+ \ilink{Messages}{MessagesChapter} -- to define where error and
+ information messages are to be sent.
+\end{itemize}
+
+\section{Storage Resource}
+\label{StorageResource}
+\index[general]{Resource!Storage}
+\index[general]{Storage Resource}
+
+In general, the properties specified under the Storage resource define global
+properties of the Storage daemon. Each Storage daemon configuration file must
+have one and only one Storage resource definition.
+
+\begin{description}
+
+\item [Name = \lt{}Storage-Daemon-Name\gt{}]
+ \index[sd]{Name}
+ \index[sd]{Directive!Name}
+ Specifies the Name of the Storage daemon. This directive is required.
+
+\item [Working Directory = \lt{}Directory\gt{}]
+ \index[sd]{Working Directory}
+ \index[sd]{Directive!Working Directory}
+ This directive is mandatory and specifies a directory in which the Storage
+ daemon may put its status files. This directory should be used only by {\bf
+ Bacula}, but may be shared by other Bacula daemons provided the names
+ given to each daemon are unique. This directive is
+ required
+
+\item [Pid Directory = \lt{}Directory\gt{}]
+ \index[sd]{Pid Directory}
+ \index[sd]{Directive!Pid Directory}
+ This directive is mandatory and specifies a directory in which the Director
+ may put its process Id file files. The process Id file is used to shutdown
+ Bacula and to prevent multiple copies of Bacula from running simultaneously.
+ This directive is required. Standard shell expansion of the {\bf Directory}
+ is done when the configuration file is read so that values such as {\bf
+ \$HOME} will be properly expanded.
+
+ Typically on Linux systems, you will set this to: {\bf /var/run}. If you are
+ not installing Bacula in the system directories, you can use the {\bf Working
+ Directory} as defined above.
+
+\item [Heartbeat Interval = \lt{}time-interval\gt{}]
+ \index[sd]{Heartbeat Interval}
+ \index[sd]{Directive!Heartbeat Interval}
+ \index[general]{Heartbeat Interval}
+ \index[general]{Broken pipe}
+ This directive defines an interval of time in seconds. When
+ the Storage daemon is waiting for the operator to mount a
+ tape, each time interval, it will send a heartbeat signal to
+ the File daemon. The default interval is zero which disables
+ the heartbeat. This feature is particularly useful if you
+ have a router such as 3Com that does not follow Internet
+ standards and times out an valid connection after a short
+ duration despite the fact that keepalive is set. This usually
+ results in a broken pipe error message.
+
+\item [Client Connect Wait = \lt{}time-interval\gt{}]
+ \index[sd]{Connect Wait}
+ \index[sd]{Directive!Connect Wait}
+ \index[general]{Client Connect Wait}
+ This directive defines an interval of time in seconds that
+ the Storage daemon will wait for a Client (the File daemon)
+ to connect. The default is 30 minutes. Be aware that the
+ longer the Storage daemon waits for a Client, the more
+ resources will be tied up.
+
+\item [Maximum Concurrent Jobs = \lt{}number\gt{}]
+ \index[sd]{Maximum Concurrent Jobs}
+ \index[sd]{Directive!Maximum Concurrent Jobs}
+ where \lt{}number\gt{} is the maximum number of Jobs that should run
+ concurrently. The default is set to 10, but you may set it to a larger
+ number. Each contact from the Director (e.g. status request, job start
+ request) is considered as a Job, so if you want to be able to do a {\bf
+ status} request in the console at the same time as a Job is running, you
+ will need to set this value greater than 1. To run simultaneous Jobs,
+ you will need to set a number of other directives in the Director's
+ configuration file. Which ones you set depend on what you want, but you
+ will almost certainly need to set the {\bf Maximum Concurrent Jobs} in
+ the Storage resource in the Director's configuration file and possibly
+ those in the Job and Client resources.
+
+\item [SDAddresses = \lt{}IP-address-specification\gt{}]
+ \index[sd]{SDAddresses}
+ \index[sd]{Directive!SDAddresses}
+ Specify the ports and addresses on which the Storage daemon will listen
+ for Director connections. Normally, the default is sufficient and you
+ do not need to specify this directive. Probably the simplest way to
+ explain how this directive works is to show an example:
+
+\footnotesize
+\begin{verbatim}
+ SDAddresses = { ip = {
+ addr = 1.2.3.4; port = 1205; }
+ ipv4 = {
+ addr = 1.2.3.4; port = http; }
+ ipv6 = {
+ addr = 1.2.3.4;
+ port = 1205;
+ }
+ ip = {
+ addr = 1.2.3.4
+ port = 1205
+ }
+ ip = {
+ addr = 1.2.3.4
+ }
+ ip = {
+ addr = 201:220:222::2
+ }
+ ip = {
+ addr = bluedot.thun.net
+ }
+}
+\end{verbatim}
+\normalsize
+
+where ip, ip4, ip6, addr, and port are all keywords. Note, that the address
+can be specified as either a dotted quadruple, or IPv6 colon notation, or as
+a symbolic name (only in the ip specification). Also, port can be specified
+as a number or as the mnemonic value from the /etc/services file. If a port
+is not specified, the default will be used. If an ip section is specified,
+the resolution can be made either by IPv4 or IPv6. If ip4 is specified, then
+only IPv4 resolutions will be permitted, and likewise with ip6.
+
+Using this directive, you can replace both the SDPort and SDAddress
+directives shown below.
+
+\item [SDPort = \lt{}port-number\gt{}]
+ \index[sd]{SDPort}
+ \index[sd]{Directive!SDPort}
+ Specifies port number on which the Storage daemon listens for Director
+ connections. The default is 9103.
+
+\item [SDAddress = \lt{}IP-Address\gt{}]
+ \index[sd]{SDAddress}
+ \index[sd]{Directive!SDAddress}
+ This directive is optional, and if it is specified, it will cause the
+ Storage daemon server (for Director and File daemon connections) to bind
+ to the specified {\bf IP-Address}, which is either a domain name or an
+ IP address specified as a dotted quadruple. If this directive is not
+ specified, the Storage daemon will bind to any available address (the
+ default).
+
+\end{description}
+
+The following is a typical Storage daemon Storage definition.
+
+\footnotesize
+\begin{verbatim}
+#
+# "Global" Storage daemon configuration specifications appear
+# under the Storage resource.
+#
+Storage {
+ Name = "Storage daemon"
+ Address = localhost
+ WorkingDirectory = "~/bacula/working"
+ Pid Directory = "~/bacula/working"
+}
+\end{verbatim}
+\normalsize
+
+\section{Director Resource}
+\label{DirectorResource1}
+\index[general]{Director Resource}
+\index[general]{Resource!Director}
+
+The Director resource specifies the Name of the Director which is permitted
+to use the services of the Storage daemon. There may be multiple Director
+resources. The Director Name and Password must match the corresponding
+values in the Director's configuration file.
+
+\begin{description}
+
+\item [Name = \lt{}Director-Name\gt{}]
+ \index[sd]{Name}
+ \index[sd]{Directive!Name}
+ Specifies the Name of the Director allowed to connect to the Storage daemon.
+ This directive is required.
+
+\item [Password = \lt{}Director-password\gt{}]
+ \index[sd]{Password}
+ \index[sd]{Directive!Password}
+ Specifies the password that must be supplied by the above named Director.
+ This directive is required.
+
+\item [Monitor = \lt{}yes|no\gt{}]
+ \index[sd]{Monitor}
+ \index[sd]{Directive!Monitor}
+ If Monitor is set to {\bf no} (default), this director will have full
+ access to this Storage daemon. If Monitor is set to {\bf yes}, this
+ director will only be able to fetch the current status of this Storage
+ daemon.
+
+ Please note that if this director is being used by a Monitor, we highly
+ recommend to set this directive to {\bf yes} to avoid serious security
+ problems.
+
+\end{description}
+
+The following is an example of a valid Director resource definition:
+
+\footnotesize
+\begin{verbatim}
+Director {
+ Name = MainDirector
+ Password = my_secret_password
+}
+\end{verbatim}
+\normalsize
+
+\label{DeviceResource}
+\section{Device Resource}
+\index[general]{Resource!Device}
+\index[general]{Device Resource}
+
+The Device Resource specifies the details of each device (normally a tape
+drive) that can be used by the Storage daemon. There may be multiple
+Device resources for a single Storage daemon. In general, the properties
+specified within the Device resource are specific to the Device.
+
+\begin{description}
+
+\item [Name = {\it Device-Name}]
+ \index[sd]{Name}
+ \index[sd]{Directive!Name}
+ Specifies the Name that the Director will use when asking to backup or
+ restore to or from to this device. This is the logical Device name, and may
+ be any string up to 127 characters in length. It is generally a good idea to
+ make it correspond to the English name of the backup device. The physical
+ name of the device is specified on the {\bf Archive Device} directive
+ described below. The name you specify here is also used in your Director's
+ conf file on the
+ \ilink{Device directive}{StorageResource2} in its Storage
+ resource.
+
+\item [Archive Device = {\it name-string}]
+ \index[sd]{Archive Device}
+ \index[sd]{Directive!Archive Device}
+ The specified {\bf name-string} gives the system file name of the storage
+ device managed by this storage daemon. This will usually be the device file
+ name of a removable storage device (tape drive), for example "{\bf
+ /dev/nst0}" or "{\bf /dev/rmt/0mbn}". For a DVD-writer, it will be for
+ example {\bf /dev/hdc}. It may also be a directory name if you are archiving
+ to disk storage. In this case, you must supply the full absolute path to the
+ directory. When specifying a tape device, it is preferable that the
+ "non-rewind" variant of the device file name be given. In addition, on
+ systems such as Sun, which have multiple tape access methods, you must be
+ sure to specify to use Berkeley I/O conventions with the device. The {\bf b}
+ in the Solaris (Sun) archive specification {\bf /dev/rmt/0mbn} is what is
+ needed in this case. Bacula does not support SysV tape drive behavior.
+
+ As noted above, normally the Archive Device is the name of a tape drive, but
+ you may also specify an absolute path to an existing directory. If the Device
+ is a directory Bacula will write to file storage in the specified directory,
+ and the filename used will be the Volume name as specified in the Catalog.
+ If you want to write into more than one directory (i.e. to spread the load to
+ different disk drives), you will need to define two Device resources, each
+ containing an Archive Device with a different directory.
+ \label{SetupFifo}
+ In addition to a tape device name or a directory name, Bacula will accept the
+ name of a FIFO. A FIFO is a special kind of file that connects two programs
+ via kernel memory. If a FIFO device is specified for a backup operation, you
+ must have a program that reads what Bacula writes into the FIFO. When the
+ Storage daemon starts the job, it will wait for {\bf MaximumOpenWait} seconds
+ for the read program to start reading, and then time it out and terminate
+ the job. As a consequence, it is best to start the read program at the
+ beginning of the job perhaps with the {\bf RunBeforeJob} directive. For this
+ kind of device, you never want to specify {\bf AlwaysOpen}, because you want
+ the Storage daemon to open it only when a job starts, so you must explicitly
+ set it to {\bf No}. Since a FIFO is a one way device, Bacula will not attempt
+ to read a label of a FIFO device, but will simply write on it. To create a
+ FIFO Volume in the catalog, use the {\bf add} command rather than the {\bf
+ label} command to avoid attempting to write a label.
+
+\footnotesize
+\begin{verbatim}
+Device {
+ Name = FifoStorage
+ Media Type = Fifo
+ Device Type = Fifo
+ Archive Device = /tmp/fifo
+ LabelMedia = yes
+ Random Access = no
+ AutomaticMount = no
+ RemovableMedia = no
+ MaximumOpenWait = 60
+ AlwaysOpen = no
+}
+\end{verbatim}
+\normalsize
+
+ During a restore operation, if the Archive Device is a FIFO, Bacula will
+ attempt to read from the FIFO, so you must have an external program that
+ writes into the FIFO. Bacula will wait {\bf MaximumOpenWait} seconds for the
+ program to begin writing and will then time it out and terminate the job. As
+ noted above, you may use the {\bf RunBeforeJob} to start the writer program
+ at the beginning of the job.
+
+ The Archive Device directive is required.
+
+\item [Device Type = {\it type-specification}]
+ \index[sd]{Device Type}
+ \index[sd]{Directive!Device Type}
+ The Device Type specification allows you to explicitly tell Bacula
+ what kind of device you are defining. It the {\it type-specification}
+ may be one of the following:
+ \begin{description}
+ \item [File]
+ Tells Bacula that the device is a file. It may either be a
+ file defined on fixed medium or a removable filesystem such as
+ USB. All files must be random access devices.
+ \item [Tape]
+ The device is a tape device and thus is sequential access. Tape devices
+ are controlled using ioctl() calls.
+ \item [Fifo]
+ The device is a first-in-first out sequential access read-only
+ or write-only device.
+ \item [DVD]
+ The device is a DVD. DVDs are sequential access for writing, but
+ random access for reading.
+ \end{description}
+
+ The Device Type directive is not required, and if not specified, Bacula
+ will attempt to guess what kind of device has been specified using the
+ Archive Device specification supplied. There are several advantages to
+ explicitly specifying the Device Type. First, on some systems, block and
+ character devices have the same type, which means that on those systems,
+ Bacula is unlikely to be able to correctly guess that a device is a DVD.
+ Secondly, if you explicitly specify the Device Type, the mount point
+ need not be defined until the device is opened. This is the case with
+ most removable devices such as USB that are mounted by the HAL daemon.
+ If the Device Type is not explicitly specified, then the mount point
+ must exist when the Storage daemon starts.
+
+ This directive was implemented in Bacula version 1.38.6.
+
+
+\item [Media Type = {\it name-string}]
+ \index[sd]{Media Type}
+ \index[sd]{Directive!Media Type}
+ The specified {\bf name-string} names the type of media supported by this
+ device, for example, "DLT7000". Media type names are arbitrary in that you
+ set them to anything you want, but they must be known to the volume
+ database to keep track of which storage daemons can read which volumes. In
+ general, each different storage type should have a unique Media Type
+ associated with it. The same {\bf name-string} must appear in the
+ appropriate Storage resource definition in the Director's configuration
+ file.
+
+ Even though the names you assign are arbitrary (i.e. you choose the name
+ you want), you should take care in specifying them because the Media Type
+ is used to determine which storage device Bacula will select during
+ restore. Thus you should probably use the same Media Type specification
+ for all drives where the Media can be freely interchanged. This is not
+ generally an issue if you have a single Storage daemon, but it is with
+ multiple Storage daemons, especially if they have incompatible media.
+
+ For example, if you specify a Media Type of "DDS-4" then during the
+ restore, Bacula will be able to choose any Storage Daemon that handles
+ "DDS-4". If you have an autochanger, you might want to name the Media Type
+ in a way that is unique to the autochanger, unless you wish to possibly use
+ the Volumes in other drives. You should also ensure to have unique Media
+ Type names if the Media is not compatible between drives. This
+ specification is required for all devices.
+
+ In addition, if you are using disk storage, each Device resource will
+ generally have a different mount point or directory. In order for
+ Bacula to select the correct Device resource, each one must have a
+ unique Media Type.

+\label{Autochanger}
+\item [Autochanger = {\it Yes|No}]
+ \index[sd]{Autochanger}
+ \index[sd]{Directive!Autochanger}
+ If {\bf Yes}, this device belongs to an automatic tape changer, and you
+ must specify an {\bf Autochanger} resource that points to the {\bf
+ Device} resources. You must also specify a
+ {\bf Changer Device}. If the Autochanger directive is set to {\bf
+ No} (default), the volume must be manually changed. You should also
+ have an identical directive to the
+ \ilink{Storage resource}{Autochanger1} in the Director's
+ configuration file so that when labeling tapes you are prompted for the slot.
+
+\item [Changer Device = {\it name-string}]
+ \index[sd]{Changer Device}
+ \index[sd]{Directive!Changer Device}
+ The specified {\bf name-string} must be the {\bf generic SCSI} device
+ name of the autochanger that corresponds to the normal read/write
+ {\bf Archive Device} specified in the Device resource. This
+ generic SCSI device name should be specified if you have an autochanger
+ or if you have a standard tape drive and want to use the
+ {\bf Alert Command} (see below). For example, on Linux systems, for
+ an Archive Device name of {\bf /dev/nst0}, you would specify {\bf
+ /dev/sg0} for the Changer Device name. Depending on your exact
+ configuration, and the number of autochangers or the type of
+ autochanger, what you specify here can vary. This directive is
+ optional. See the \ilink{ Using Autochangers}{AutochangersChapter} chapter
+ of this manual for more details of using this and the following
+ autochanger directives.
+
+\item [Changer Command = {\it name-string}]
+ \index[sd]{Changer Command}
+ \index[sd]{Directive!Changer Command}
+ The {\bf name-string} specifies an external program to be called that will
+ automatically change volumes as required by {\bf Bacula}. Normally,
+ this directive will be specified only in the {\bf AutoChanger} resource,
+ which is then used for all devices. However, you may also specify
+ the different {\bf Changer Command} in each Device resource.
+ Most frequently,
+ you will specify the Bacula supplied {\bf mtx-changer} script as follows:
+
+\footnotesize
+\begin{verbatim}
+Changer Command = "/path/mtx-changer %c %o %S %a %d"
+\end{verbatim}
+\normalsize
+
+ and you will install the {\bf mtx} on your system (found in the {\bf depkgs}
+ release). An example of this command is in the default bacula-sd.conf file.
+ For more details on the substitution characters that may be specified to
+ configure your autochanger please see the
+ \ilink{Autochangers}{AutochangersChapter} chapter of this manual.
+ For FreeBSD users, you might want to see one of the several {\bf chio}
+ scripts in {\bf examples/autochangers}.
+
+\item [Alert Command = {\it name-string}]
+ \index[sd]{Alert Command}
+ The {\bf name-string} specifies an external program to be called at the
+ completion of each Job after the device is released. The purpose of this
+ command is to check for Tape Alerts, which are present when something is
+ wrong with your tape drive (at least for most modern tape drives). The same
+ substitution characters that may be specified in the Changer Command may also
+ be used in this string. For more information, please see the
+ \ilink{Autochangers}{AutochangersChapter} chapter of this manual.
+
+
+ Note, it is not necessary to have an autochanger to use this command. The
+ example below uses the {\bf tapeinfo} program that comes with the {\bf mtx}
+ package, but it can be used on any tape drive. However, you will need to
+ specify a {\bf Changer Device} directive in your Device resource (see above)
+ so that the generic SCSI device name can be edited into the command (with the
+ \%c).
+
+ An example of the use of this command to print Tape Alerts in the Job report
+ is:
+
+\footnotesize
+\begin{verbatim}
+Alert Command = "sh -c 'tapeinfo -f %c | grep TapeAlert'"
+
+\end{verbatim}
+\normalsize
+
+and an example output when there is a problem could be:
+
+\footnotesize
+\begin{verbatim}
+bacula-sd Alert: TapeAlert[32]: Interface: Problem with SCSI interface
+ between tape drive and initiator.
+
+\end{verbatim}
+\normalsize
+
+\item [Drive Index = {\it number}]
+ \index[sd]{Drive Index}
+ \index[sd]{Directive!Drive Index}
+ The {\bf Drive Index} that you specify is passed to the {\bf
+ mtx-changer} script and is thus passed to the {\bf mtx} program. By
+ default, the Drive Index is zero, so if you have only one drive in your
+ autochanger, everything will work normally. However, if you have
+ multiple drives, you must specify multiple Bacula Device resources (one
+ for each drive). The first Device should have the Drive Index set to 0,
+ and the second Device Resource should contain a Drive Index set to 1,
+ and so on. This will then permit you to use two or more drives in your
+ autochanger. As of Bacula version 1.38.0, using the {\bf Autochanger}
+ resource, Bacula will automatically ensure that only one drive at a time
+ uses the autochanger script, so you no longer need locking scripts as in
+ the past -- the default mtx-changer script works for any number of
+ drives.
+
+\item [Autoselect = {\it Yes|No}]
+ \index[sd]{Autoselect}
+ \index[sd]{Directive!Autoselect}
+ If this directive is set to {\bf yes} (default), and the Device
+ belongs to an autochanger, then when the Autochanger is referenced
+ by the Director, this device can automatically be selected. If this
+ directive is set to {\bf no}, then the Device can only be referenced
+ by directly using the Device name in the Director. This is useful
+ for reserving a drive for something special such as a high priority
+ backup or restore operations.
+
+\item [Maximum Changer Wait = {\it time}]
+ \index[sd]{Maximum Changer Wait}
+ \index[sd]{Directive!Maximum Changer Wait}
+ This directive specifies the maximum time in seconds for Bacula to wait
+ for an autochanger to change the volume. If this time is exceeded,
+ Bacula will invalidate the Volume slot number stored in the catalog and
+ try again. If no additional changer volumes exist, Bacula will ask the
+ operator to intervene. The default is 5 minutes.
+% TODO: if this is the format, then maybe "5 minutes" should be in
+% TODO: quotes? define style. see others.
+
+\item [Maximum Rewind Wait = {\it time}]
+ \index[sd]{Maximum Rewind Wait}
+ \index[sd]{Directive!Maximum Rewind Wait}
+ This directive specifies the maximum time in seconds for Bacula to wait
+ for a rewind before timing out. If this time is exceeded,
+ Bacula will cancel the job. The default is 5 minutes.
+
+\item [Maximum Open Wait = {\it time}]
+ \index[sd]{Maximum Open Wait}
+ \index[sd]{Directive!Maximum Open Wait}
+ This directive specifies the maximum time in seconds for Bacula to wait
+ for a open before timing out. If this time is exceeded,
+ Bacula will cancel the job. The default is 5 minutes.
+
+\item [Always Open = {\it Yes|No}]
+ \index[sd]{Always Open}
+ \index[sd]{Directive!Always Open}
+ If {\bf Yes} (default), Bacula will always keep the device open unless
+ specifically {\bf unmounted} by the Console program. This permits
+ Bacula to ensure that the tape drive is always available, and properly
+ positioned. If you set
+ {\bf AlwaysOpen} to {\bf no} {\bf Bacula} will only open the drive when
+ necessary, and at the end of the Job if no other Jobs are using the
+ drive, it will be freed. The next time Bacula wants to append to a tape
+ on a drive that was freed, Bacula will rewind the tape and position it to
+ the end. To avoid unnecessary tape positioning and to minimize
+ unnecessary operator intervention, it is highly recommended that {\bf
+ Always Open = yes}. This also ensures that the drive is available when
+ Bacula needs it.
+
+ If you have {\bf Always Open = yes} (recommended) and you want to use the
+ drive for something else, simply use the {\bf unmount} command in the Console
+ program to release the drive. However, don't forget to remount the drive with
+ {\bf mount} when the drive is available or the next Bacula job will block.
+
+ For File storage, this directive is ignored. For a FIFO storage device, you
+ must set this to {\bf No}.
+
+ Please note that if you set this directive to {\bf No} Bacula will release
+ the tape drive between each job, and thus the next job will rewind the tape
+ and position it to the end of the data. This can be a very time consuming
+ operation. In addition, with this directive set to no, certain multiple
+ drive autochanger operations will fail. We strongly recommend to keep
+ {\bf Always Open} set to {\bf Yes}
+
+\item [Volume Poll Interval = {\it time}]
+ \index[sd]{Volume Poll Interval}
+ \index[sd]{Directive!Volume Poll Interval}
+ If the time specified on this directive is non-zero, after asking the
+ operator to mount a new volume Bacula will periodically poll (or read) the
+ drive at the specified interval to see if a new volume has been mounted. If
+ the time interval is zero (the default), no polling will occur. This
+ directive can be useful if you want to avoid operator intervention via the
+ console. Instead, the operator can simply remove the old volume and insert
+ the requested one, and Bacula on the next poll will recognize the new tape
+ and continue. Please be aware that if you set this interval too small, you
+ may excessively wear your tape drive if the old tape remains in the drive,
+ since Bacula will read it on each poll. This can be avoided by ejecting the
+ tape using the {\bf Offline On Unmount} and the {\bf Close on Poll}
+ directives.
+ However, if you are using a Linux 2.6 kernel or other OSes
+ such as FreeBSD or Solaris, the Offline On Unmount will leave the drive
+ with no tape, and Bacula will not be able to properly open the drive and
+ may fail the job. For more information on this problem, please see the
+ \ilink{description of Offline On Unmount}{NoTapeInDrive} in the Tape
+ Testing chapter.
+
+\item [Close on Poll= {\it Yes|No}]
+ \index[sd]{Close on Poll}
+ \index[sd]{Directive!Close on Poll}
+ If {\bf Yes}, Bacula close the device (equivalent to an unmount except no
+ mount is required) and reopen it at each poll. Normally this is not too
+ useful unless you have the {\bf Offline on Unmount} directive set, in which
+ case the drive will be taken offline preventing wear on the tape during any
+ future polling. Once the operator inserts a new tape, Bacula will recognize
+ the drive on the next poll and automatically continue with the backup.
+ Please see above more more details.
+
+\item [Maximum Open Wait = {\it time}]
+ \index[sd]{Maximum Open Wait}
+ \index[sd]{Directive!Maximum Open Wait}
+ This directive specifies the maximum amount of time in seconds that
+ Bacula will wait for a device that is busy. The default is 5 minutes.
+ If the device cannot be obtained, the current Job will be terminated in
+ error. Bacula will re-attempt to open the drive the next time a Job
+ starts that needs the the drive.
+
+\label{removablemedia}
+\item [Removable media = {\it Yes|No}]
+ \index[sd]{Removable media}
+ \index[sd]{Directive!Removable media}
+ If {\bf Yes}, this device supports removable media (for example, tapes
+ or CDs). If {\bf No}, media cannot be removed (for example, an
+ intermediate backup area on a hard disk). If {\bf Removable media} is
+ enabled on a File device (as opposed to a tape) the Storage daemon will
+ assume that device may be something like a USB device that can be
+ removed or a simply a removable harddisk. When attempting to open
+ such a device, if the Volume is not found (for File devices, the Volume
+ name is the same as the Filename), then the Storage daemon will search
+ the entire device looking for likely Volume names, and for each one
+ found, it will ask the Director if the Volume can be used. If so,
+ the Storage daemon will use the first such Volume found. Thus it
+ acts somewhat like a tape drive -- if the correct Volume is not found,
+ it looks at what actually is found, and if it is an appendable Volume,
+ it will use it.
+
+ If the removable medium is not automatically mounted (e.g. udev), then
+ you might consider using additional Storage daemon device directives
+ such as {\bf Requires Mount}, {\bf Mount Point}, {\bf Mount Command},
+ and {\bf Unmount Command}, all of which can be used in conjunction with
+ {\bf Removable Media}.
+
+
+\item [Random access = {\it Yes|No}]
+ \index[sd]{Random access}
+ \index[sd]{Directive!Random access}
+ If {\bf Yes}, the archive device is assumed to be a random access medium
+ which supports the {\bf lseek} (or {\bf lseek64} if Largefile is enabled
+ during configuration) facility. This should be set to {\bf Yes} for all
+ file systems such as DVD, USB, and fixed files. It should be set to
+ {\bf No} for non-random access devices such as tapes and named pipes.
+
+
+\item [Requires Mount = {\it Yes|No}]
+ \index[sd]{Requires Mount }
+ When this directive is enabled, the Storage daemon will submit
+ a {\bf Mount Command} before attempting to open the device.
+ You must set this directive to {\bf yes} for DVD-writers and removable
+ file systems such as USB devices that are not automatically mounted
+ by the operating system when plugged in or opened by Bacula.
+ It should be set to {\bf no} for
+ all other devices such as tapes and fixed filesystems. It should also
+ be set to {\bf no} for any removable device that is automatically
+ mounted by the operating system when opened (e.g. USB devices mounted
+ by udev or hotplug). This directive
+ indicates if the device requires to be mounted using the {\bf Mount
+ Command}. To be able to write a DVD, the following directives must also
+ be defined: {\bf Mount Point}, {\bf Mount Command}, {\bf Unmount
+ Command} and {\bf Write Part Command}.
+
+\item [Mount Point = {\it directory}]
+ \index[sd]{Mount Point}
+ Directory where the device can be mounted.
+ This directive is used only
+ for devices that have {\bf Requires Mount} enabled such as DVD or
+ USB file devices.
+
+\item [Mount Command = {\it name-string}]
+ \index[sd]{Mount Command}
+ This directive specifies the command that must be executed to mount
+ devices such as DVDs and many USB devices. For DVDs, the
+ device is written directly, but the mount command is necessary in
+ order to determine the free space left on the DVD. Before the command is
+ executed, \%a is replaced with the Archive Device, and \%m with the Mount
+ Point.
+
+ Most frequently, for a DVD, you will define it as follows:
+
+\footnotesize
+\begin{verbatim}
+ Mount Command = "/bin/mount -t iso9660 -o ro %a %m"
+\end{verbatim}
+\normalsize
+
+However, if you have defined a mount point in /etc/fstab, you might be
+able to use a mount command such as:
+
+\footnotesize
+\begin{verbatim}
+ Mount Command = "/bin/mount /media/dvd"
+\end{verbatim}
+\normalsize
+
+See the \ilink {Edit Codes}{mountcodes} section below for more details of
+the editing codes that can be used in this directive.
+
+ If you need to specify multiple commands, create a shell script.
+
+\item [Unmount Command = {\it name-string}]
+ \index[sd]{Unmount Command}
+ This directive specifies the command that must be executed to unmount
+ devices such as DVDs and many USB devices. Before the command is
+ executed, \%a is replaced with the Archive Device, and \%m with the Mount
+ Point.
+
+ Most frequently, you will define it as follows:
+
+\footnotesize
+\begin{verbatim}
+ Unmount Command = "/bin/umount %m"
+\end{verbatim}
+\normalsize
+
+See the \ilink {Edit Codes}{mountcodes} section below for more details of
+the editing codes that can be used in this directive.
+
+ If you need to specify multiple commands, create a shell script.
+
+\item [Minimum block size = {\it size-in-bytes}]
+ \index[sd]{Minimum block size}
+ \index[sd]{Directive!Minimum block size}
+ On most modern tape drives, you will not need or want to specify this
+ directive, and if you do so, it will be to make Bacula use fixed block
+ sizes. This statement applies only to non-random access devices (e.g.
+ tape drives). Blocks written by the storage daemon to a non-random
+ archive device will never be smaller than the given {\bf size-in-bytes}.
+ The Storage daemon will attempt to efficiently fill blocks with data
+ received from active sessions but will, if necessary, add padding to a
+ block to achieve the required minimum size.
+
+ To force the block size to be fixed, as is the case for some non-random
+ access devices (tape drives), set the {\bf Minimum block size} and the
+ {\bf Maximum block size} to the same value (zero included). The default
+ is that both the minimum and maximum block size are zero and the default
+ block size is 64,512 bytes.
+
+ For example, suppose you want a fixed block size of 100K bytes, then you
+ would specify:
+
+\footnotesize
+\begin{verbatim}
+
+ Minimum block size = 100K
+ Maximum block size = 100K
+
+\end{verbatim}
+\normalsize
+
+ Please note that if you specify a fixed block size as shown above, the tape
+ drive must either be in variable block size mode, or if it is in fixed block
+ size mode, the block size (generally defined by {\bf mt}) {\bf must} be
+ identical to the size specified in Bacula -- otherwise when you attempt to
+ re-read your Volumes, you will get an error.
+
+ If you want the block size to be variable but with a 64K minimum and 200K
+ maximum (and default as well), you would specify:
+
+\footnotesize
+\begin{verbatim}
+
+ Minimum block size = 64K
+ Maximum blocksize = 200K
+
+\end{verbatim}
+\normalsize
+
+\item [Maximum block size = {\it size-in-bytes}]
+ \index[sd]{Maximum block size}
+ \index[sd]{Directive!Maximum block size}
+ On most modern tape drives, you will not need to specify this directive.
+ If you do so, it will most likely be to use fixed block sizes (see
+ Minimum block size above). The Storage daemon will always attempt to
+ write blocks of the specified {\bf size-in-bytes} to the archive device.
+ As a consequence, this statement specifies both the default block size
+ and the maximum block size. The size written never exceed the given
+ {\bf size-in-bytes}. If adding data to a block would cause it to exceed
+ the given maximum size, the block will be written to the archive device,
+ and the new data will begin a new block.
+
+ If no value is specified or zero is specified, the Storage daemon will
+ use a default block size of 64,512 bytes (126 * 512).
+
+ The maximum {\bf size-in-bytes} possible is 2,000,000.
+
+\item [Hardware End of Medium = {\it Yes|No}]
+ \index[sd]{Hardware End of Medium}
+ \index[sd]{Directive!Hardware End of Medium}
+ If {\bf No}, the archive device is not required to support end of medium
+ ioctl request, and the storage daemon will use the forward space file
+ function to find the end of the recorded data. If {\bf Yes}, the archive
+ device must support the {\tt ioctl} {\tt MTEOM} call, which will position the
+ tape to the end of the recorded data. In addition, your SCSI driver must keep
+ track of the file number on the tape and report it back correctly by the
+ {\bf MTIOCGET} ioctl. Note, some SCSI drivers will correctly forward space to
+ the end of the recorded data, but they do not keep track of the file number.
+ On Linux machines, the SCSI driver has a {\bf fast-eod} option, which if set
+ will cause the driver to lose track of the file number. You should ensure
+ that this option is always turned off using the {\bf mt} program.
+
+ Default setting for Hardware End of Medium is {\bf Yes}. This function is
+ used before appending to a tape to ensure that no previously written data is
+ lost. We recommend if you have a non-standard or unusual tape drive that you
+ use the {\bf btape} program to test your drive to see whether or not it
+ supports this function. All modern (after 1998) tape drives support this
+ feature.
+
+\item [Fast Forward Space File = {\it Yes|No}]
+ \index[sd]{Fast Forward Space File}
+ \index[sd]{Directive!Fast Forward Space File}
+ If {\bf No}, the archive device is not required to support keeping track of
+ the file number ({\bf MTIOCGET} ioctl) during forward space file. If {\bf
+ Yes}, the archive device must support the {\tt ioctl} {\tt MTFSF} call, which
+ virtually all drivers support, but in addition, your SCSI driver must keep
+ track of the file number on the tape and report it back correctly by the
+ {\bf MTIOCGET} ioctl. Note, some SCSI drivers will correctly forward space,
+ but they do not keep track of the file number or more seriously, they do not
+ report end of medium.
+
+ Default setting for Fast Forward Space File is {\bf Yes}.
+
+\item [Use MTIOCGET = {\it Yes|No}]
+ \index[sd]{Use MTIOCGET}
+ \index[sd]{Directive!Use MTIOCGET}
+ If {\bf No}, the operating system is not required to support keeping track of
+ the file number and reporting it in the ({\bf MTIOCGET} ioctl). The default
+ is {\bf Yes}. If you must set this to No, Bacula will do the proper file
+ position determination, but it is very unfortunate because it means that
+ tape movement is very inefficient.
+ Fortunately, this operation system deficiency seems to be the case only
+ on a few *BSD systems. Operating systems known to work correctly are
+ Solaris, Linux and FreeBSD.
+
+\item [BSF at EOM = {\it Yes|No}]
+ \index[sd]{BSF at EOM}
+ \index[sd]{Directive!BSF at EOM}
+ If {\bf No}, the default, no special action is taken by Bacula with the End
+ of Medium (end of tape) is reached because the tape will be positioned after
+ the last EOF tape mark, and Bacula can append to the tape as desired.
+ However, on some systems, such as FreeBSD, when Bacula reads the End of
+ Medium (end of tape), the tape will be positioned after the second EOF tape
+ mark (two successive EOF marks indicated End of Medium). If Bacula appends
+ from that point, all the appended data will be lost. The solution for such
+ systems is to specify {\bf BSF at EOM} which causes Bacula to backspace over
+ the second EOF mark. Determination of whether or not you need this directive
+ is done using the {\bf test} command in the {\bf btape} program.
+
+\item [TWO EOF = {\it Yes|No}]
+ \index[sd]{TWO EOF}
+ \index[sd]{Directive!TWO EOF}
+ If {\bf Yes}, Bacula will write two end of file marks when terminating a tape
+-- i.e. after the last job or at the end of the medium. If {\bf No}, the
+default, Bacula will only write one end of file to terminate the tape.
+
+\item [Backward Space Record = {\it Yes|No}]
+ \index[sd]{Backward Space Record}
+ \index[sd]{Directive!Backward Space Record}
+ If {\it Yes}, the archive device supports the {\tt MTBSR ioctl} to backspace
+ records. If {\it No}, this call is not used and the device must be rewound
+ and advanced forward to the desired position. Default is {\bf Yes} for non
+ random-access devices. This function if enabled is used at the end of a
+ Volume after writing the end of file and any ANSI/IBM labels to determine whether
+ or not the last block was written correctly. If you turn this function off,
+ the test will not be done. This causes no harm as the re-read process is
+ precautionary rather than required.
+
+\item [Backward Space File = {\it Yes|No}]
+ \index[sd]{Backward Space File}
+ \index[sd]{Directive!Backward Space File}
+ If {\it Yes}, the archive device supports the {\bf MTBSF} and {\bf MTBSF
+ ioctl}s to backspace over an end of file mark and to the start of a file. If
+ {\it No}, these calls are not used and the device must be rewound and
+ advanced forward to the desired position. Default is {\bf Yes} for non
+ random-access devices.
+
+\item [Forward Space Record = {\it Yes|No}]
+ \index[sd]{Forward Space Record}
+ \index[sd]{Directive!Forward Space Record}
+ If {\it Yes}, the archive device must support the {\bf MTFSR ioctl} to
+ forward space over records. If {\bf No}, data must be read in order to
+ advance the position on the device. Default is {\bf Yes} for non
+ random-access devices.
+
+\item [Forward Space File = {\it Yes|No}]
+ \index[sd]{Forward Space File}
+ \index[sd]{Directive!Forward Space File}
+ If {\bf Yes}, the archive device must support the {\tt MTFSF ioctl} to
+ forward space by file marks. If {\it No}, data must be read to advance the
+ position on the device. Default is {\bf Yes} for non random-access devices.
+
+\item [Offline On Unmount = {\it Yes|No}]
+ \index[sd]{Offline On Unmount}
+ \index[sd]{Directive!Offline On Unmount}
+ The default for this directive is {\bf No}. If {\bf Yes} the archive device
+ must support the {\tt MTOFFL ioctl} to rewind and take the volume offline. In
+ this case, Bacula will issue the offline (eject) request before closing the
+ device during the {\bf unmount} command. If {\bf No} Bacula will not attempt
+ to offline the device before unmounting it. After an offline is issued, the
+ cassette will be ejected thus {\bf requiring operator intervention} to
+ continue, and on some systems require an explicit load command to be issued
+ ({\bf mt -f /dev/xxx load}) before the system will recognize the tape. If you
+ are using an autochanger, some devices require an offline to be issued prior
+ to changing the volume. However, most devices do not and may get very
+ confused.
+
+ If you are using a Linux 2.6 kernel or other OSes
+ such as FreeBSD or Solaris, the Offline On Unmount will leave the drive
+ with no tape, and Bacula will not be able to properly open the drive and
+ may fail the job. For more information on this problem, please see the
+ \ilink{description of Offline On Unmount}{NoTapeInDrive} in the Tape
+ Testing chapter.
+
+
+\item [Maximum Volume Size = {\it size}]
+ \index[sd]{Maximum Volume Size}
+ \index[sd]{Directive!Maximum Volume Size}
+ No more than {\bf size} bytes will be written onto a given volume on the
+ archive device. This directive is used mainly in testing Bacula to
+ simulate a small Volume. It can also be useful if you wish to limit the
+ size of a File Volume to say less than 2GB of data. In some rare cases
+ of really antiquated tape drives that do not properly indicate when the
+ end of a tape is reached during writing (though I have read about such
+ drives, I have never personally encountered one). Please note, this
+ directive is deprecated (being phased out) in favor of the {\bf Maximum
+ Volume Bytes} defined in the Director's configuration file.
+
+\item [Maximum File Size = {\it size}]
+ \index[sd]{Maximum File Size}
+ \index[sd]{Directive!Maximum File Size}
+ No more than {\bf size} bytes will be written into a given logical file
+ on the volume. Once this size is reached, an end of file mark is
+ written on the volume and subsequent data are written into the next
+ file. Breaking long sequences of data blocks with file marks permits
+ quicker positioning to the start of a given stream of data and can
+ improve recovery from read errors on the volume. The default is one
+ Gigabyte. This directive creates EOF marks only on tape media.
+ However, regardless of the medium type (tape, disk, DVD, ...) each time
+ a the Maximum File Size is exceeded, a record is put into the catalog
+ database that permits seeking to that position on the medium for
+ restore operations. If you set this to a small value (e.g. 1MB),
+ you will generate lots of database records (JobMedia) and may
+ significantly increase CPU/disk overhead.
+
+ If you are configuring an LTO-3 or LTO-4 tape, you probably will
+ want to set the {\bf Maximum File Size} to 2GB to avoid making
+ the drive stop to write an EOF mark.
+
+ Note, this directive does not limit the size of Volumes that Bacula
+ will create regardless of whether they are tape or disk volumes. It
+ changes only the number of EOF marks on a tape and the number of
+ block positioning records (see below) that are generated. If you
+ want to limit the size of all Volumes for a particular device, use
+ the {\bf Maximum Volume Size} directive (above), or use the
+ {\bf Maximum Volume Bytes} directive in the Director's Pool resource,
+ which does the same thing but on a Pool (Volume) basis.
+
+\item [Block Positioning = {\it yes|no}]
+ \index[sd]{Block Positioning}
+ \index[sd]{Directive!Block Positioning}
+ This directive tells Bacula not to use block positioning when doing restores.
+ Turning this directive off can cause Bacula to be {\bf extremely} slow
+ when restoring files. You might use this directive if you wrote your
+ tapes with Bacula in variable block mode (the default), but your drive
+ was in fixed block mode. The default is {\bf yes}.
+
+\item [Maximum Network Buffer Size = {\it bytes}]
+ \index[sd]{Maximum Network Buffer Size}
+ \index[sd]{Directive!Maximum Network Buffer Size}
+ where {\it bytes} specifies the initial network buffer size to use with the
+ File daemon. This size will be adjusted down if it is too large until
+ it is accepted by the OS. Please use care in setting this value since if
+ it is too large, it will be trimmed by 512 bytes until the OS is happy,
+ which may require a large number of system calls. The default value is
+ 32,768 bytes.
+
+ The default size was chosen to be relatively large but not too big in
+ the case that you are transmitting data over Internet. It is clear that
+ on a high speed local network, you can increase this number and improve
+ performance. For example, some users have found that if you use a value
+ of 65,536 bytes they get five to ten times the throughput. Larger values for
+ most users don't seem to improve performance. If you are interested
+ in improving your backup speeds, this is definitely a place to
+ experiment. You will probably also want to make the corresponding change
+ in each of your File daemons conf files.
+
+
+\item [Maximum Spool Size = {\it bytes}]
+ \index[sd]{Maximum Spool Size}
+ \index[sd]{Directive!Maximum Spool Size}
+ where the bytes specify the maximum spool size for all jobs that are running.
+ The default is no limit.
+
+\item [Maximum Job Spool Size = {\it bytes}]
+ \index[sd]{Maximum Job Spool Size}
+ \index[sd]{Directive!Maximum Job Spool Size}
+ where the bytes specify the maximum spool size for any one job that is
+ running. The default is no limit.
+ This directive is implemented only in version 1.37 and later.
+
+\item [Spool Directory = {\it directory}]
+ \index[sd]{Spool Directory}
+ \index[sd]{Directive!Spool Directory}
+ specifies the name of the directory to be used to store the spool files for
+ this device. This directory is also used to store temporary part files when
+ writing to a device that requires mount (DVD). The default is to use the
+ working directory.
+
+\item [Maximum Part Size = {\it bytes}]
+ \index[sd]{Maximum Part Size}
+ \index[sd]{Directive!Maximum Part Size}
+ This is the maximum size of a volume part file. The default is no limit.
+ This directive is implemented only in version 1.37 and later.
+
+ If the device requires mount, it is transferred to the device when this size
+ is reached. In this case, you must take care to have enough disk space left
+ in the spool directory.
+
+ Otherwise, it is left on the hard disk.
+
+ It is ignored for tape and FIFO devices.

+
+\footnotesize
+\begin{verbatim}
+ %% = %
+ %a = Archive device name

+\index[general]{Devices that require a mount (DVD)}
+\index[general]{DVD!Devices that require a mount}
+
+All the directives in this section are implemented only in
+Bacula version 1.37 and later and hence are available in version 1.38.6.
+
+As of version 1.39.5, the directives
+"Requires Mount", "Mount Point", "Mount Command", and "Unmount Command"
+apply to removable filesystems such as USB in addition to DVD.
+
+\begin{description}
+
+\item [Requires Mount = {\it Yes|No}]
+ \index[sd]{Requires Mount}
+ \index[sd]{Directive!Requires Mount}
+ You must set this directive to {\bf yes} for DVD-writers, and to {\bf no} for
+ all other devices (tapes/files). This directive indicates if the device
+ requires to be mounted to be read, and if it must be written in a special way.
+ If it set, {\bf Mount Point}, {\bf Mount Command}, {\bf Unmount Command} and
+ {\bf Write Part Command} directives must also be defined.
+
+\item [Mount Point = {\it directory}]
+ \index[sd]{Mount Point}
+ \index[sd]{Directive!Mount Point}
+ Directory where the device can be mounted.
+
+\item [Mount Command = {\it name-string}]
+ \index[sd]{Mount Command}
+ \index[sd]{Directive!Mount Command}
+ Command that must be executed to mount the device. Before the command is
+ executed, \%a is replaced with the Archive Device, and \%m with the Mount
+ Point.
+
+ Most frequently, you will define it as follows:
+
+\footnotesize
+\begin{verbatim}
+ Mount Command = "/bin/mount -t iso9660 -o ro %a %m"
+\end{verbatim}
+\normalsize
+
+For some media, you may need multiple commands. If so, it is recommended
+that you use a shell script instead of putting them all into the Mount
+Command. For example, instead of this:
+
+\footnotesize
+\begin{verbatim}
+ Mount Command = "/usr/local/bin/mymount"
+\end{verbatim}
+\normalsize
+
+Where that script contains:
+
+\footnotesize
+\begin{verbatim}
+#!/bin/sh
+ndasadmin enable -s 1 -o w
+sleep 2
+mount /dev/ndas-00323794-0p1 /backup
+\end{verbatim}
+\normalsize
+
+Similar consideration should be given to all other Command parameters.
+
+\item [Unmount Command = {\it name-string}]
+ \index[sd]{Unmount Command}
+ \index[sd]{Directive!Unmount Command}
+ Command that must be executed to unmount the device. Before the command is
+ executed, \%a is replaced with the Archive Device, and \%m with the Mount
+ Point.
+
+ Most frequently, you will define it as follows:
+
+\footnotesize
+\begin{verbatim}
+ Unmount Command = "/bin/umount %m"
+\end{verbatim}
+\normalsize
+
+ If you need to specify multiple commands, create a shell script.
+
+\item [Write Part Command = {\it name-string}]
+ \index[sd]{Write Part Command}
+ \index[sd]{Directive!Write Part Command}
+ Command that must be executed to write a part to the device. Before the
+ command is executed, \%a is replaced with the Archive Device, \%m with the
+ Mount Point, \%e is replaced with 1 if we are writing the first part,
+ and with 0 otherwise, and \%v with the current part filename.
+
+ For a DVD, you will most frequently specify the Bacula supplied {\bf
+ dvd-handler} script as follows:
+
+\footnotesize
+\begin{verbatim}
+ Write Part Command = "/path/dvd-handler %a write %e %v"
+\end{verbatim}
+\normalsize
+
+ Where {\bf /path} is the path to your scripts install directory, and
+ dvd-handler is the Bacula supplied script file.
+ This command will already be present, but commented out,
+ in the default bacula-sd.conf file. To use it, simply remove
+ the comment (\#) symbol.
+
+ If you need to specify multiple commands, create a shell script.
+
+
+\item [Free Space Command = {\it name-string}]
+ \index[sd]{Free Space Command}
+ \index[sd]{Directive!Free Space Command}
+ Command that must be executed to check how much free space is left on the
+ device. Before the command is executed,\%a is replaced with the Archive
+ Device, \%m with the Mount Point, \%e is replaced with 1 if we are writing
+ the first part, and with 0 otherwise, and \%v with the current part filename.
+
+ For a DVD, you will most frequently specify the Bacula supplied {\bf
+ dvd-handler} script as follows:
+
+\footnotesize
+\begin{verbatim}
+ Free Space Command = "/path/dvd-handler %a free"
+\end{verbatim}
+\normalsize
+
+ Where {\bf /path} is the path to your scripts install directory, and
+ dvd-handler is the Bacula supplied script file.
+ If you want to specify your own command, please look at the code of
+ dvd-handler to see what output Bacula expects from this command.
+ This command will already be present, but commented out,
+ in the default bacula-sd.conf file. To use it, simply remove
+ the comment (\#) symbol.
+
+ If you do not set it, Bacula will expect there is always free space on the
+ device.
+
+ If you need to specify multiple commands, create a shell script.

+\begin{description}
+
+\item [Label media = {\it Yes|No}]
+ \index[sd]{Label media}
+ \index[sd]{Directive!Label media}
+ If {\bf Yes}, permits this device to automatically label blank media
+ without an explicit operator command. It does so by using an internal
+ algorithm as defined on the \ilink{Label Format}{Label} record in each
+ Pool resource. If this is {\bf No} as by default, Bacula will label
+ tapes only by specific operator command ({\bf label} in the Console) or
+ when the tape has been recycled. The automatic labeling feature is most
+ useful when writing to disk rather than tape volumes.
+
+\item [Automatic mount = {\it Yes|No}]
+ \index[sd]{Automatic mount}
+ \index[sd]{Directive!Automatic mount}
+ If {\bf Yes} (the default), permits the daemon to examine the device to
+ determine if it contains a Bacula labeled volume. This is done
+ initially when the daemon is started, and then at the beginning of each
+ job. This directive is particularly important if you have set
+ {\bf Always Open = no} because it permits Bacula to attempt to read the
+ device before asking the system operator to mount a tape. However,
+ please note that the tape must be mounted before the job begins.

+
+\begin{description}
+\label{what}
+\section{What is Bacula?}
+\item [What is {\bf Bacula}? ]
+ \index[general]{What is Bacula? }
+ {\bf Bacula} is a network backup and restore program.
+
+\section{Does Bacula support Windows?}
+\item [Does Bacula support Windows?]
+\index[general]{Does Bacula support Windows? }
+ Yes, Bacula compiles and runs on Windows machines (Win98, WinMe, WinXP,
+ WinNT, Win2003, and Win2000). We provide a binary version of the Client
+ (bacula-fd), but have not tested the Director nor the Storage daemon.
+ Note, Win95 is no longer supported because it doesn't have the
+ GetFileAttributesExA API call.
+
+
+\label{lang}
+\section{What language is Bacula written in?}
+\item [What language is Bacula written in?]
+\index[general]{What language is Bacula written in? }
+ It is written in C++, but it is mostly C code using only a limited set of
+ the C++ extensions over C. Thus Bacula is completely compiled using the
+ C++ compiler. There are several modules, including the Win32 interface, that
+ are written using the object oriented C++ features. Over time, we are slowly
+ adding a larger subset of C++.
+
+\label{run}
+\section{On what machines does Bacula run?}
+\item [On what machines does Bacula run? ]
+ \index[general]{On what machines does Bacula run? }
+ {\bf Bacula} builds and executes on Red Hat Linux (versions RH7.1-RHEL
+ 4.0, Fedora, SuSE, Gentoo, Debian, Mandriva, ...), FreeBSD, Solaris,
+ Alpha, SGI (client), NetBSD, OpenBSD, Mac OS X (client), and Win32.
+
+ Bacula has been my only backup tool for over seven years backing up 8
+ machines nightly (6 Linux boxes running SuSE, previously
+ Red Hat and Fedora, a WinXP machine, and a WinNT machine).
+
+
+\label{stable}
+\section{Is Bacula Stable?}
+\item [Is Bacula Stable? ]
+\index[general]{Is Bacula Stable? }
+ Yes, it is remarkably stable, but remember, there are still a lot of
+ unimplemented or partially implemented features. With a program of this
+ size (150,000+ lines of C++ code not including the SQL programs) there
+ are bound to be bugs. The current test environment (a twisted pair
+ local network and a HP DLT backup tape) is not exactly ideal, so
+ additional testing on other sites is necessary. The File daemon has
+ never crashed -- running months at a time with no intervention. The
+ Storage daemon is remarkably stable with most of the problems arising
+ during labeling or switching tapes. Storage daemon crashes are rare
+ but running multiple drives and simultaneous jobs sometimes (rarely)
+ problems.
+ The Director, given the multitude of functions it fulfills is also
+ relatively stable. In a production environment, it rarely if ever
+ crashes. Of the three daemons, the Director is the most prone to having
+ problems. Still, it frequently runs several months with no problems.
+
+ There are a number of reasons for this stability.
+
+ \begin{enumerate}
+ \item The program is constantly checking the chain of allocated
+ memory buffers to ensure that no overruns have occurred. \\
+ \item All memory leaks (orphaned buffers) are reported each time the
+ program terminates.\\
+ \item Any signal (segmentation fault, ...) generates a
+ traceback that is emailed to the developer. This permits quick
+ resolution of bugs even if they only show up rarely in a production
+ system.\\
+ \item There is a reasonably comprehensive set of regression tests
+ that avoids re-creating the most common errors in new versions of
+ Bacula.
+ \end{enumerate}
+
+\label{AuthorizationErrors}
+\section{I'm Getting Authorization Errors. What is Going On? }
+\item [I'm Getting Authorization Errors. What is Going On? ]
+\index[general]{Authorization Errors}
+\index[general]{Concurrent Jobs}
+ For security reasons, Bacula requires that both the File daemon and the
+ Storage daemon know the name of the Director as well as its password. As a
+ consequence, if you change the Director's name or password, you must make
+ the corresponding change in the Storage daemon's and in the File daemon's
+ configuration files.
+
+ During the authorization process, the Storage daemon and File daemon
+ also require that the Director authenticates itself, so both ends
+ require the other to have the correct name and password.
+
+ If you have edited the conf files and modified any name or any password,
+ and you are getting authentication errors, then your best bet is to go
+ back to the original conf files generated by the Bacula installation
+ process. Make only the absolutely necessary modifications to these
+ files -- e.g. add the correct email address. Then follow the
+ instructions in the \ilink{ Running Bacula}{TutorialChapter} chapter of
+ this manual. You will run a backup to disk and a restore. Only when
+ that works, should you begin customization of the conf files.
+
+ Another reason that you can get authentication errors is if you are
+ running Multiple Concurrent Jobs in the Director, but you have not set
+ them in the File daemon or the Storage daemon. Once you reach their
+ limit, they will reject the connection producing authentication (or
+ connection) errors.
+
+ If you are having problems connecting to a Windows machine that
+ previously worked, you might try restarting the Bacula service since
+ Windows frequently encounters networking connection problems.
+
+ Some users report that authentication fails if there is not a proper
+ reverse DNS lookup entry for the machine. This seems to be a
+ requirement of gethostbyname(), which is what Bacula uses to translate
+ names into IP addresses. If you cannot add a reverse DNS entry, or you
+ don't know how to do so, you can avoid the problem by specifying an IP
+ address rather than a machine name in the appropriate Bacula conf file.
+
+ Here is a picture that indicates what names/passwords in which
+ files/Resources must match up:
+
+ \includegraphics{\idir Conf-Diagram.eps}
+
+ In the left column, you will find the Director, Storage, and Client
+ resources, with their names and passwords -- these are all in {\bf
+ bacula-dir.conf}. The right column is where the corresponding values
+ should be found in the Console, Storage daemon (SD), and File daemon (FD)
+ configuration files.
+
+ Another thing to check is to ensure that the Bacula component you are
+ trying to access has {\bf Maximum Concurrent Jobs} set large enough to
+ handle each of the Jobs and the Console that want to connect
+ simultaneously. Once the maximum connections has been reached, each
+ Bacula component will reject all new connections.
+
+ Finally, make sure you have no {\bf hosts.allow} or {\bf hosts.deny}
+ file that is not permitting access to the site trying to connect.
+
+\label{AccessProblems}
+\section{Bacula Runs Fine but Cannot Access a Client on a Different Machine.
+ Why? }
+\item [Bacula Runs Fine but Cannot Access a Client on a Different Machine.
+ Why? ]
+\index[general]{Cannot Access a Client}
+ There are several reasons why Bacula could not contact a client on a
+ different machine. They are:
+
+\begin{itemize}
+\item It is a Windows Client, and the client died because of an improper
+ configuration file. Check that the Bacula icon is in the system tray and the
+ the menu items work. If the client has died, the icon will disappear only
+ when you move the mouse over the icon.
+\item The Client address or port is incorrect or not resolved by DNS. See if
+ you can ping the client machine using the same address as in the Client
+ record.
+\item You have a firewall, and it is blocking traffic on port 9102 between
+ the Director's machine and the Client's machine (or on port 9103 between the
+ Client and the Storage daemon machines).
+\item Your password or names are not correct in both the Director and the
+ Client machine. Try configuring everything identical to how you run the
+ client on the same machine as the Director, but just change the Address. If
+ that works, make the other changes one step at a time until it works.
+\item You may also be having problems between your File daemon and your
+ Storage daemon. The name you use in the Storage resource of your
+ Director's conf file must be known (resolvable) by the File daemon,
+ because it is passed symbolically to the File daemon, which then
+ resolves it to get an IP address used to contact the Storage daemon.
+\item You may have a {\bf hosts.allow} or {\bf hosts.deny} file that is
+ not permitting access.
+\end{itemize}
+
+\label{startover}
+\section{My Catalog is Full of Test Runs, How Can I Start Over?}
+\item [My Catalog is Full of Test Runs, How Can I Start Over? ]
+ \index[general]{My Catalog is Full of Test Runs, How Can I Start Over? }
+ If you are using MySQL do the following:
+
+\footnotesize
+\begin{verbatim}
+ cd <bacula-source>/src/cats
+ ./drop_mysql_tables
+ ./make_mysql_tables
+
+\end{verbatim}
+\normalsize
+
+If you are using SQLite, do the following:
+
+\footnotesize
+\begin{verbatim}
+ Delete bacula.db from your working directory.
+ cd <bacula-source>/src/cats
+ ./drop_sqlite_tables
+ ./make_sqlite_tables
+
+\end{verbatim}
+\normalsize
+
+Then write an EOF on each tape you used with {\bf Bacula} using:
+
+\footnotesize
+\begin{verbatim}
+mt -f /dev/st0 rewind
+mt -f /dev/st0 weof
+\end{verbatim}
+\normalsize
+
+where you need to adjust the device name for your system.
+
+\label{restorehang}
+\section{I Run a Restore Job and Bacula Hangs. What do I do?}
+\item [I Run a Restore Job and Bacula Hangs. What do I do?]
+\index[general]{I Run a Restore Job and Bacula Hangs. What do I do? }
+ On Bacula version 1.25 and prior, it expects you to have the correct
+ tape mounted prior to a restore. On Bacula version 1.26 and higher, it
+ will ask you for the tape, and if the wrong one is mounted, it will
+ inform you.
+
+ If you have previously done an {\bf unmount} command, all Storage daemon
+ sessions (jobs) will be completely blocked from using the drive
+ unmounted, so be sure to do a {\bf mount} after your unmount. If in
+ doubt, do a second {\bf mount}, it won't cause any harm.
+
+\label{windowstart}
+\section{I Cannot Get My Windows Client to Start Automatically? }
+\item [I Cannot Get My Windows Client to Start Automatically? ]
+\index[general]{Windows Auto Start}
+ You are probably having one of two problems: either the Client is dying
+ due to an incorrect configuration file, or you didn't do the
+ Installation commands necessary to install it as a Windows Service.
+
+ For the first problem, see the next FAQ question. For the second
+ problem, please review the \ilink{ Windows Installation
+ instructions}{Win32Chapter} in this manual.
+
+\label{windowsdie}
+\section{My Windows Client Immediately Dies When I Start It}
+\item [My Windows Client Immediately Dies When I Start It]
+\index[general]{Windows Client Dies}
+The most common problem is either that the configuration file is not where
+it expects it to be, or that there is an error in the configuration file.
+You must have the configuration file in {\bf
+c:\textbackslash{}bacula\textbackslash{}bin\textbackslash{}bacula-fd.conf}.
+
+To {\bf see} what is going on when the File daemon starts on Windows, do the
+following:
+
+\footnotesize
+\begin{verbatim}
+ Start a DOS shell Window.
+ cd c:\bacula\bin
+ bacula-fd -d100 -c c:\bacula\bin\bacula-fd.conf
+
+\end{verbatim}
+\normalsize
+
+This will cause the FD to write a file {\bf bacula.trace} in the current
+directory, which you can examine and thereby determine the problem.
+
+\label{scroll}
+\item [When I Start the Console, the Error Messages Fly By. How can I see
+ them? ]
+\index[general]{Error Messages}
+ Either use a shell window with a scroll bar, or use the gnome-console.
+ In any case, you probably should be logging all output to a file, and
+ then you can simply view the file using an editor or the {\bf less}
+ program. To log all output, I have the following in my Director's
+ Message resource definition:
+
+\footnotesize
+\begin{verbatim}
+ append = "/home/kern/bacula/bin/log" = all, !skipped
+
+\end{verbatim}
+\normalsize
+
+Obviously you will want to change the filename to be appropriate for your
+system.
+
+\label{nobackup}
+\section{My backups are not working on my Windows
+ Client. What should I do?}
+\item [I didn't realize that the backups were not working on my Windows
+ Client. What should I do? ]
+\index[general]{Backups Failing}
+You should be sending yourself an email message for each job. This will avoid
+the possibility of not knowing about a failed backup. To do so put something
+like:

+\index[general]{Schedule problems}
+ No, not at all. Bacula will schedule all the Jobs at the same time, but
+ will run them one after another unless you have increased the number of
+ simultaneous jobs in the configuration files for the Director, the File
+ daemon, and the Storage daemon. The appropriate configuration record is
+ {\bf Maximum Concurrent Jobs = nn}. At the current time, we recommend

+\section{Can Bacula Backup My System To Files instead of Tape?}
+\item [Can Bacula Backup My System To Files instead of Tape? ]
+\index[general]{Backup to Disk}
+ Yes, in principle, Bacula can backup to any storage medium as long as
+ you have correctly defined that medium in the Storage daemon's Device
+ resource. For an example of how to backup to files, please see the
+ \ilink{Pruning Example}{PruningExample} in the Recycling chapter of this

+\label{sure}
+\section{Does Bacula really save and restore all files?}
+\item [How Can I Be Sure that Bacula Really Saves and Restores All Files? ]
+\index[general]{Checking Restores}
+ It is really quite simple, but took me a while to figure
+ out how to "prove" it. First make a Bacula Rescue disk, see the
+ \ilink{Disaster Recovery Using Bacula}{RescueChapter} chapter
+ of this manual.
+ Second, you run a full backup of all your files on all partitions.
+ Third, you run an Verify InitCatalog Job on the same FileSet, which
+ effectively makes a record of all the files on your system. Fourth, you
+ run a Verify Catalog job and assure yourself that nothing has changed
+ (well, between an InitCatalog and Catalog one doesn't expect anything).
+ Then do the unthinkable, write zeros on your MBR (master boot record)
+ wiping out your hard disk. Now, restore your whole system using your
+ Bacula Rescue disk and the Full backup you made, and finally re-run the
+ Verify Catalog job. You will see that with the exception of the
+ directory modification and access dates and the files changed during the
+ boot, your system is identical to what it was before you wiped your hard
+ disk.
+ Alternatively you could do the wiping and restoring to another computer
+ of the same type.
+
+\label{upgrade}
+\section{I want an Incremental but Bacula runs it as a Full backup. Why?}
+\item [I did a Full backup last week, but now in running an Incremental,
+ Bacula says it did not find a FULL backup, so it did a FULL backup. Why?]
+\index[general]{FULL backup not found}
+ Before doing an Incremental or a Differential
+ backup, Bacula checks to see if there was a prior Full backup of the
+ same Job that terminated successfully. If so, it uses the date that
+ full backup started as the time for comparing if files have changed. If
+ Bacula does not find a successful full backup, it proceeds to do one.
+ Perhaps you canceled the full backup, or it terminated in error. In
+ such cases, the full backup will not be successful. You can check by
+ entering {\bf list jobs} and look to see if there is a prior Job with
+ the same Name that has Level F and JobStatus T (normal termination).
+
+ Another reason why Bacula may not find a suitable Full backup is that
+ every time you change the FileSet, Bacula will require a new Full
+ backup. This is necessary to ensure that all files are properly backed
+ up in the case where you have added more files to the FileSet.
+ Beginning with version 1.31, the FileSets are also dated when they are
+ created, and this date is displayed with the name when you are listing
+ or selecting a FileSet. For more on backup levels see below.
+
+ See also {\bf Ignore FileSet Changes} in the
+ \ilink{FileSet Resource definition}{FileSetResource} in the Director
+ chapter of this document.
+
+\label{filenamelengths}
+\section{Do you really handle unlimited path lengths?}
+\item [How Can You Claim to Handle Unlimited Path and Filename Lengths
+ when All Other Programs Have Fixed Limits?]
+\index[general]{Path and Filename Lengths}
+ Most of those other programs have been around for a long time, in fact
+ since the beginning of Unix, which means that they were designed for
+ rather small fixed length path and filename lengths. Over the years,
+ these restrictions have been relaxed allowing longer names. Bacula on
+ the other hand was designed in 2000, and so from the start, Path and
+ Filenames have been kept in buffers that start at 256 bytes in length,
+ but can grow as needed to handle any length. Most of the work is
+ carried out by lower level routines making the coding rather easy.
+
+ Note that due to limitations Win32 path and filenames cannot exceed
+ 260 characters. By using Win32 Unicode functions, we will remove this
+ restriction in later versions of Bacula.
+
+\label{unique}
+\section{What Is the Really Unique Feature of Bacula?}
+\item [What Is the Really Unique Feature of Bacula?]
+\index[general]{Unique Feature of Bacula}
+ Well, it is hard to come up with unique features when backup programs
+ for Unix machines have been around since the 1960s. That said, I
+ believe that Bacula is the first and only program to use a standard SQL
+ interface to catalog its database. Although this adds a bit of
+ complexity and possibly overhead, it provides an amazingly rich set of
+ features that are easy to program and enhance. The current code has
+ barely scratched the surface in this regard (version 1.38).
+
+ The second feature, which gives a lot of power and flexibility to Bacula
+ is the Bootstrap record definition.
+
+ The third unique feature, which is currently (1.30) unimplemented, and
+ thus can be called vaporware :-), is Base level saves. When
+ implemented, this will enormously reduce tape usage.
+
+\label{sequence}
+\section{How can I force one job to run after another?}
+\item [If I Run Multiple Simultaneous Jobs, How Can I Force One
+ Particular Job to Run After Another Job? ]
+\index[general]{Multiple Simultaneous Jobs}
+Yes, you can set Priorities on your jobs so that they run in the order you
+specify. Please see:
+\ilink{the Priority record}{Priority} in the Job resource.
+
+\label{nomail}
+\section{I Am Not Getting Email Notification, What Can I Do? }
+\item [I Am Not Getting Email Notification, What Can I Do? ]
+\index[general]{No Email Notification}
+ The most common problem is that you have not specified a fully qualified
+ email address and your bsmtp server is rejecting the mail. The next
+ most common problem is that your bsmtp server doesn't like the syntax on
+ the From part of the message. For more details on this and other
+ problems, please see the \ilink{ Getting Email Notification to
+ Work}{email} section of the Tips chapter of this manual. The section
+ \ilink{ Getting Notified of Job Completion}{notification} of the Tips

+ chapter}{bsmtp} of this manual.
+
+\label{periods}
+\section{My retention periods don't work}
+\item [I Change Recycling, Retention Periods, or File Sizes in my Pool
+ Resource and they Still Don't Work.]
+\index[general]{Recycling}
+\index[general]{Retention Periods}
+\index[general]{Pool changes}
+ The different variables associated with a Pool are defined in the Pool
+ Resource, but are actually read by Bacula from the Catalog database. On
+ Bacula versions prior to 1.30, after changing your Pool Resource, you must
+ manually update the corresponding values in the Catalog by using the {\bf
+ update pool} command in the Console program. In Bacula version 1.30, Bacula
+ does this for you automatically every time it starts.
+
+ When Bacula creates a Media record (Volume), it uses many default values from
+ the Pool record. If you subsequently change the Pool record, the new values
+ will be used as a default for the next Volume that is created, but if you
+ want the new values to apply to existing Volumes, you must manually update
+ the Volume Catalog entry using the {\bf update volume} command in the Console
+ program.
+
+\label{CompressionNotWorking}
+\section{Why aren't my files compressed?}
+\item [I Have Configured Compression On, But None of My Files Are
+ Compressed. Why?]
+\index[general]{Compression}
+ There are two kinds of compression. One is tape compression. This is done by
+ the tape drive hardware, and you either enable or disable it with system
+ tools such as {\bf mt}. This compression works independently of Bacula,
+ and when it is enabled, you should not use the Bacula software
+ compression.
+
+ Bacula also has software compression code in the File daemons, which you
+ normally need to enable only when backing up to file Volumes. There are
+ two conditions necessary to enable the Bacula software compression.
+
+\begin{enumerate}
+\item You must have the zip development libraries loaded on your system
+ when building Bacula and Bacula must find this library, normally {\bf
+ /usr/lib/libz.a}. On Red Hat systems, this library is provided by the
+ {\bf zlib-devel} rpm.
+
+ If the library is found by Bacula during the {\bf ./configure} it will
+ be mentioned in the {\bf config.out} line by:
+
+\footnotesize
+\begin{verbatim}
+ ZLIB support: yes
+
+\end{verbatim}
+\normalsize
+
+\item You must add the {\bf compression=gzip} option on your Include
+ statement in the Director's configuration file.
+\end{enumerate}
+
+\label{NewTape}
+\item [Bacula is Asking for a New Tape After 2 GB of Data but My Tape
+ holds 33 GB. Why?]
+\index[general]{Tape capacity}
+There are several reasons why Bacula will request a new tape.
+
+\begin{itemize}
+\item There is an I/O error on the tape. Bacula prints an error message and
+ requests a new tape. Bacula does not attempt to continue writing after an
+ I/O error.
+\item Bacula encounters and end of medium on the tape. This is not always
+ distinguishable from an I/O error.
+\item You have specifically set some size limitation on the tape. For example
+ the {\bf Maximum Volume Bytes} or {\bf Maximum Volume Files} in the
+ Director's Pool resource, or {\bf Maximum Volume Size} in the Storage
+ daemon's Device resource.
+\end{itemize}
+
+\label{LevelChanging}
+\section{Incremental backups are not working}
+\item [Bacula is Not Doing the Right Thing When I Request an Incremental
+ Backup. Why?]
+\index[general]{Incremental backups}
+ As explained in one of the previous questions, Bacula will automatically
+ upgrade an Incremental or Differential job to a Full backup if it cannot
+ find a prior Full backup or a suitable Full backup. For the gory
+ details on how/when Bacula decides to upgrade levels please see the
+ \ilink{Level record}{Level} in the Director's configuration chapter of
+ this manual.
+
+ If after reading the above mentioned section, you believe that Bacula is not
+ correctly handling the level (Differential/Incremental), please send us the
+ following information for analysis:
+
+\begin{itemize}
+\item Your Director's configuration file.
+\item The output from {\bf list jobs} covering the period where you are
+ having the problem.
+\item The Job report output from the prior Full save (not critical).
+\item An {\bf llist jobid=nnn} where nnn is the JobId of the prior Full save.
+
+\item The Job report output from the save that is doing the wrong thing (not
+ critical).
+\item An {\bf llist jobid=nnn} where nnn is the JobId of the job that was not
+ correct.
+\item An explanation of what job went wrong and why you think it did.
+ \end{itemize}
+
+The above information can allow us to analyze what happened, without it,
+there is not much we can do.
+
+\label{WaitForever}
+\section{I am waiting forever for a backup of an offsite machine}
+\item [I am Backing Up an Offsite Machine with an Unreliable Connection.
+ The Director Waits Forever for the Client to Contact the SD. What Can I
+ Do?]
+\index[general]{Backing Up Offsite Machines}
+ Bacula was written on the assumption that it will have a good TCP/IP
+ connection between all the daemons. As a consequence, the current
+ Bacula doesn't deal with faulty connections very well. This situation
+ is slowly being corrected over time.
+
+ There are several things you can do to improve the situation.
+
+\begin{itemize}
+\item Upgrade to version 1.32 and use the new SDConnectTimeout record. For
+ example, set:
+
+\footnotesize
+\begin{verbatim}
+ SD Connect Timeout = 5 min
+
+\end{verbatim}
+\normalsize
+
+in the FileDaemon resource.
+\item Run these kinds of jobs after all other jobs.
+ \end{itemize}
+
+\label{sshHanging}
+\section{SSH hangs forever after starting Bacula}
+\item [When I ssh into a machine and start Bacula then attempt to exit,
+ ssh hangs forever.]
+\index[general]{ssh hangs}
+ This happens because Bacula leaves stdin, stdout, and stderr open for
+ debug purposes. To avoid it, the simplest thing to do is to redirect
+ the output of those files to {\bf /dev/null} or another file in your
+ startup script (the Red Hat autostart scripts do this automatically).
+ For example, you start the Director with:
+
+\footnotesize
+\begin{verbatim}
+ bacula-dir -c bacula-dir.conf ... >/dev/null 0>\&1 2>\&1
+
+\end{verbatim}
+\normalsize
+
+and likewise for the other daemons.
+
+\label{RetentionPeriods}
+\section{I'm confused by retention periods}
+\item [I'm confused by the different Retention periods: File Retention,
+ Job Retention, Volume Retention. Why are there so many?]
+\index[general]{Retention Periods}
+ Yes, this certainly can be confusing. The basic reason for so many is
+ to allow flexibility. The File records take quite a lot of space in the
+ catalog, so they are typically records you want to remove rather
+ quickly. The Job records, take very little space, and they can be
+ useful even without the File records to see what Jobs actually ran and
+ when. One must understand that if the File records are removed from the
+ catalog, you cannot use the {\bf restore} command to restore an
+ individual file since Bacula no longer knows where it is. However, as
+ long as the Volume Retention period has not expired, the data will still
+ be on the tape, and can be recovered from the tape.
+
+ For example, I keep a 30 day retention period for my Files to keep my
+ catalog from getting too big, but I keep my tapes for a minimum of one
+ year, just in case.
+
+\label{MaxVolumeSize}
+\section{MaxVolumeSize is ignored}
+\item [Why Does Bacula Ignore the MaxVolumeSize Set in my Pool?]
+\index[general]{MaxVolumeSize}
+ The MaxVolumeSize that Bacula uses comes from the Media record, so most
+ likely you changed your Pool, which is used as the default for creating
+ Media records, {\bf after} you created your Volume. Check what is in
+ the Media record by doing:
+
+\footnotesize
+\begin{verbatim}
+llist Volume=xxx
+\end{verbatim}
+\normalsize
+
+If it doesn't have the right value, you can use:
+
+\footnotesize
+\begin{verbatim}
+update Volume=xxx
+\end{verbatim}
+\normalsize
+
+to change it.
+
+\label{ConnectionRefused}
+\section{I get a Connection refused when connecting to my Client}
+\item [In connecting to my Client, I get "ERR:Connection Refused. Packet
+ Size too big from File daemon:192.168.1.4:9102" Why?]
+\index[general]{ERR:Connection Refused}
+ This is typically a communications error resulting from one of the
+ following:
+
+
+\begin{itemize}
+\item Old versions of Bacula, usually a Win32 client, where two threads were
+ using the same I/O packet. Fixed in more recent versions. Please upgrade.
+\item Some other program such as an HP Printer using the same port (9102 in
+ this case).
+\end{itemize}
+
+If it is neither of the above, please submit a bug report at
+\elink{bugs.bacula.org}{http://bugs.bacula.org}.
+
+Another solution might be to run the daemon with the debug option by:
+
+\footnotesize
+\begin{verbatim}
+ Start a DOS shell Window.
+ cd c:\bacula\bin
+ bacula-fd -d100 -c c:\bacula\bin\bacula-fd.conf
+
+\end{verbatim}
+\normalsize
+
+This will cause the FD to write a file {\bf bacula.trace} in the current
+directory, which you can examine to determine the problem.
+
+\section{Long running jobs die with Pipe Error}
+\item [During long running jobs my File daemon dies with Pipe Error, or
+ some other communications error. Why?]
+\index[general]{Communications Errors}
+\index[general]{Pipe Errors}
+\index[general]{slow}
+\index[general]{Backups!slow}
+ There are a number of reasons why a connection might break.
+ Most often, it is a router between your two computers that times out
+ inactive lines (not respecting the keepalive feature that Bacula uses).
+ In that case, you can use the {\bf Heartbeat Interval} directive in
+ both the Storage daemon and the File daemon.
+
+ In at least one case, the problem has been a bad driver for a Win32
+ NVidia NForce 3 ethernet card with driver (4.4.2 17/05/2004).
+ In this case, a good driver is (4.8.2.0 06/04/2005). Moral of
+ the story, make sure you have the latest ethernet drivers
+ loaded, or use the following workaround as suggested by Thomas
+ Simmons for Win32 machines:
+
+ Browse to:
+ Start \gt{} Control Panel \gt{} Network Connections
+
+ Right click the connection for the nvidia adapter and select properties.
+ Under the General tab, click "Configure...". Under the Advanced tab set
+ "Checksum Offload" to disabled and click OK to save the change.
+
+ Lack of communications, or communications that get interrupted can
+ also be caused by Linux firewalls where you have a rule that throttles
+ connections or traffic. For example, if you have:
+
+\footnotesize
+\begin{verbatim}
+iptables -t filter -A INPUT -m limit --limit 3/second --limit-burst 3 -j DROP
+\end{verbatim}
+\normalsize
+
+ you will want to add the following rules {\bf before} the above rule:
+\footnotesize
+\begin{verbatim}
+iptables -t filter -A INPUT --dport 9101 -j ACCEPT
+iptables -t filter -A INPUT --dport 9102 -j ACCEPT
+iptables -t filter -A INPUT --dport 9103 -j ACCEPT
+\end{verbatim}
+\normalsize
+ This will ensure that any Bacula traffic will not get terminated because
+ of high usage rates.
+
+\section{How do I tell the Job which Volume to use?}
+\item[I can't figure out how to tell the job which volume to use]
+ \index[general]{What tape to mount}
+ This is an interesting statement. I now see that a number of people new to
+ Bacula have the same problem as you, probably from using programs like tar.
+
+ In fact, you do not tell Bacula what tapes to use. It is the inverse. Bacula
+ tells you want tapes it wants. You put tapes at its disposition and it
+ chooses.
+
+ Now, if you *really* want to be tricky and try to tell Bacula what to do, it
+ will be reasonable if for example you mount a valid tape that it can use on a
+ drive, it will most likely go ahead and use it. It also has a documented
+ algorithm for choosing tapes -- but you are asking for problems ...
+
+ So, the trick is to invert your concept of things and put Bacula in charge of
+ handling the tapes. Once you do that, you will be fine. If you want to
+ anticipate what it is going to do, you can generally figure it out correctly
+ and get what you want.
+
+ If you start with the idea that you are going to force or tell Bacula to use
+ particular tapes or you insist on trying to run in that kind of mode, you will
+ probably not be too happy.
+
+ I don't want to worry about what tape has what data. That is what Bacula is
+ designed for.
+
+ If you have an application where you *really* need to remove a tape each day
+ and insert a new one, it can be done the directives exist to accomplish that.
+ In such a case, one little "trick" to knowing what tape Bacula will want at
+ 2am while you are asleep is to run a tiny job at 4pm while you are still at
+ work that backs up say one directory, or even one file. You will quickly find
+ out what tape it wants, and you can mount it before you go home ...
+
+\label{Password generation}
+\section{Password generation}
+\item [How do I generate a password?]
+\index[general]{MaxVolumeSize}
+
+ Each daemon needs a password. This password occurs in the configuration
+ file for that daemon and in the bacula-dir.conf file. These passwords are
+ plain text. There is no special generation procedure. Most people just
+ use random text.
+
+ Passwords are never sent over the wire in plain text. They are always
+ encrypted.
+
+ Security surrounding these passwords is best left security to your
+ operating system. Passwords are not encrypted within Bacula
+ configuration files.

+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text. A copy that is not "Transparent" is called \textbf{"Opaque"}.
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input format, SGML
+or XML using a publicly available DTD, and standard-conforming simple
+HTML, PostScript or PDF designed for human modification. Examples of
+transparent image formats include PNG, XCF and JPG. Opaque formats
+include proprietary formats that can be read and edited only by
+proprietary word processors, SGML or XML for which the DTD and/or
+processing tools are not generally available, and the
+machine-generated HTML, PostScript or PDF produced by some word
+processors for output purposes only.
+
+The \textbf{"Title Page"} means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, "Title Page" means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+A section \textbf{"Entitled XYZ"} means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language. (Here XYZ stands for a
+specific section name mentioned below, such as \textbf{"Acknowledgements"},
+\textbf{"Dedications"}, \textbf{"Endorsements"}, or \textbf{"History"}.)
+To \textbf{"Preserve the Title"}
+of such a section when you modify the Document means that it remains a
+section "Entitled XYZ" according to this definition.

+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document. These Warranty
+Disclaimers are considered to be included by reference in this

+{\Large\bf 2. VERBATIM COPYING}
+\end{center}
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+
+\begin{center}
+{\Large\bf 3. COPYING IN QUANTITY}
+\end{center}
+
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.

+
+\begin{center}
+{\Large\bf 4. MODIFICATIONS}
+\end{center}
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+\begin{itemize}
+\item[A.]
+ Use in the Title Page (and on the covers, if any) a title distinct
+ from that of the Document, and from those of previous versions
+ (which should, if there were any, be listed in the History section
+ of the Document). You may use the same title as a previous version
+ if the original publisher of that version gives permission.
+
+\item[B.]
+ List on the Title Page, as authors, one or more persons or entities
+ responsible for authorship of the modifications in the Modified
+ Version, together with at least five of the principal authors of the
+ Document (all of its principal authors, if it has fewer than five),
+ unless they release you from this requirement.
+
+\item[C.]
+ State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+
+\item[D.]
+ Preserve all the copyright notices of the Document.
+
+\item[E.]
+ Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+
+\item[F.]
+ Include, immediately after the copyright notices, a license notice
+ giving the public permission to use the Modified Version under the
+ terms of this License, in the form shown in the Addendum below.
+
+\item[G.]
+ Preserve in that license notice the full lists of Invariant Sections
+ and required Cover Texts given in the Document's license notice.
+
+\item[H.]
+ Include an unaltered copy of this License.
+
+\item[I.]
+ Preserve the section Entitled "History", Preserve its Title, and add
+ to it an item stating at least the title, year, new authors, and
+ publisher of the Modified Version as given on the Title Page. If
+ there is no section Entitled "History" in the Document, create one
+ stating the title, year, authors, and publisher of the Document as
+ given on its Title Page, then add an item describing the Modified
+ Version as stated in the previous sentence.
+
+\item[J.]
+ Preserve the network location, if any, given in the Document for
+ public access to a Transparent copy of the Document, and likewise
+ the network locations given in the Document for previous versions
+ it was based on. These may be placed in the "History" section.
+ You may omit a network location for a work that was published at
+ least four years before the Document itself, or if the original
+ publisher of the version it refers to gives permission.
+
+\item[K.]
+ For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the section all
+ the substance and tone of each of the contributor acknowledgements
+ and/or dedications given therein.
+
+\item[L.]
+ Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section titles.
+
+\item[M.]
+ Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+
+\item[N.]
+ Do not retitle any existing section to be Entitled "Endorsements"
+ or to conflict in title with any Invariant Section.
+
+\item[O.]
+ Preserve any Warranty Disclaimers.
+\end{itemize}
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled "Endorsements", provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+
+\begin{center}
+{\Large\bf 5. COMBINING DOCUMENTS}
+\end{center}
+
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled "History"
+in the various original documents, forming one section Entitled
+"History"; likewise combine any sections Entitled "Acknowledgements",
+and any sections Entitled "Dedications". You must delete all sections
+Entitled "Endorsements".
+
+\begin{center}
+{\Large\bf 6. COLLECTIONS OF DOCUMENTS}
+\end{center}
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+
+\begin{center}
+{\Large\bf 7. AGGREGATION WITH INDEPENDENT WORKS}
+\end{center}
+
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an "aggregate" if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+
+\begin{center}
+{\Large\bf 8. TRANSLATION}
+\end{center}
+
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers. In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled "Acknowledgements",
+"Dedications", or "History", the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+
+\begin{center}
+{\Large\bf 9. TERMINATION}
+\end{center}
+
+
+You may not copy, modify, sublicense, or distribute the Document except
+as expressly provided for under this License. Any other attempt to
+copy, modify, sublicense or distribute the Document is void, and will
+automatically terminate your rights under this License. However,
+parties who have received copies, or rights, from you under this
+License will not have their licenses terminated so long as such
+parties remain in full compliance.

+\end{center}
+
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time. Such new
+versions will be similar in spirit to the present version, but may

+
+If you have a firewall or a DMZ installed on your computer, you may experience
+difficulties contacting one or more of the Clients to back them up. This is
+especially true if you are trying to backup a Client across the Internet.
+
+\section{Technical Details}
+\index[general]{Technical Details }
+\index[general]{Details!Technical }
+
+If you are attempting to do this, the sequence of network events in Bacula to
+do a backup are the following:
+
+\footnotesize
+\begin{verbatim}
+Console -> DIR:9101
+DIR -> SD:9103
+DIR -> FD:9102
+FD -> SD:9103
+\end{verbatim}
+\normalsize
+
+Where hopefully it is obvious that DIR represents the Director, FD the File
+daemon or client, and SD the Storage daemon. The numbers that follow those
+names are the standard ports used by Bacula, and the -\gt{} represents the
+left side making a connection to the right side (i.e. the right side is the
+"server" or is listening on the specified port), and the left side is the
+"client" that initiates the conversation.
+
+Note, port 9103 serves both the Director and the File daemon, each having its
+own independent connection.
+
+If you are running {\bf iptables}, you might add something like:
+
+\footnotesize
+\begin{verbatim}
+-A FW-1-INPUT -m state --state NEW -m tcp -p tcp --dport 9101:9103 -j ACCEPT
+\end{verbatim}
+\normalsize
+
+on your server, and
+
+\footnotesize
+\begin{verbatim}
+-A FW-1-INPUT -m state --state NEW -m tcp -p tcp --dport 9102 -j ACCEPT
+\end{verbatim}
+\normalsize
+
+on your client. In both cases, I assume that the machine is allowed to
+initiate connections on any port. If not, you will need to allow outgoing
+connections on ports 9102 and 9103 on your server and 9103 on your client.
+Thanks to Raymond Norton for this tip.
+
+\section{A Concrete Example}
+\index[general]{Example!Concrete }
+\index[general]{Concrete Example }
+
+The following discussion was originally written by
+Jesse Guardiani because he has 'internal' and 'external' requiring the
+Director and the Client to use different IP addresses. His original
+solution was to define two different Storage resources in the Director's
+conf file each pointing to the same Storage daemon but with different
+IP addresses. In Bacula 1.38.x this no longer works, because Bacula makes
+a one-to-one association between a Storage daemon resource and a Device (such
+as an Autochanger). As a consequence, I have modified his original
+text to a method that I believe will work, but is as of yet untested
+(KES - July 2006).
+
+My bacula server is on the 192.168.1.0/24 network at IP address 192.168.1.52.
+For the sake of discussion we will refer to this network as the 'internal'
+network because it connects to the internet through a NAT'd firewall. We will
+call the network on the public (internet) side of the NAT'd firewall the
+'external' network. Also, for the sake of discussion we will call my bacula
+server:
+
+\footnotesize
+\begin{verbatim}
+ server.int.mydomain.tld
+\end{verbatim}
+\normalsize
+
+when a fully qualified domain name is required, or simply:
+
+\footnotesize
+\begin{verbatim}
+ server
+\end{verbatim}
+\normalsize
+
+if a hostname is adequate. We will call the various bacula daemons running on
+the server.int.mydomain.tld machine:
+
+\footnotesize
+\begin{verbatim}
+ server-fd
+ server-sd
+ server-dir
+\end{verbatim}
+\normalsize
+
+In addition, I have two clients that I want to back up with Bacula. The first
+client is on the internal network. Its fully qualified domain name is:
+
+\footnotesize
+\begin{verbatim}
+ private1.int.mydomain.tld
+\end{verbatim}
+\normalsize
+
+And its hostname is:
+
+\footnotesize
+\begin{verbatim}
+ private1
+\end{verbatim}
+\normalsize
+
+This machine is a client and therefore runs just one bacula daemon:
+
+\footnotesize
+\begin{verbatim}
+ private1-fd
+\end{verbatim}
+\normalsize
+
+The second client is on the external network. Its fully qualified domain name
+is:
+
+\footnotesize
+\begin{verbatim}
+ public1.mydomain.tld
+\end{verbatim}
+\normalsize
+
+And its hostname is:
+
+\footnotesize
+\begin{verbatim}
+ public1
+\end{verbatim}
+\normalsize
+
+This machine also runs just one bacula daemon:
+
+\footnotesize
+\begin{verbatim}
+ public1-fd
+\end{verbatim}
+\normalsize
+
+Finally, I have a NAT firewall/gateway with two network interfaces. The first
+interface is on the internal network and serves as a gateway to the internet
+for all the machines attached to the internal network (For example,
+server.int.mydomain.tld and private1.int.mydomain.tld). The second interface
+is on the external (internet) network. The external interface has been
+assigned the name:
+
+\footnotesize
+\begin{verbatim}
+ firewall.mydomain.tld
+\end{verbatim}
+\normalsize
+
+Remember:
+
+\footnotesize
+\begin{verbatim}
+ *.int.mydomain.tld = internal network
+ *.mydomain.tld = external network
+\end{verbatim}
+\normalsize
+
+\subsection{The Bacula Configuration Files for the Above}
+\index[general]{Above!Bacula Configuration Files for the }
+\index[general]{Bacula Configuration Files for the Above }
+
+server-sd manages a 4 tape AIT autoloader. All of my backups are written to
+server-sd. I have just *one* Device resource in my server-sd.conf file:
+
+\footnotesize
+\begin{verbatim}
+Autochanger {
+ Name = "autochanger1";\
+ Device = Drive0
+ Changer Device = /dev/ch0;
+ Changer Command = "/usr/local/sbin/chio-bacula %c %o %S %a";
+}
+Device {
+ Name = Drive0
+ DriveIndex = 0
+ Media Type = AIT-1;
+ Archive Device = /dev/nrsa1;
+ Label Media = yes;
+ AutoChanger = yes;
+ AutomaticMount = yes; # when device opened, read it
+ AlwaysOpen = yes;
+ Hardware End of Medium = No
+ Fast Forward Space File = No
+ BSF at EOM = yes
+}
+\end{verbatim}
+\normalsize
+
+(note, please see
+\ilink{the Tape Testing}{FreeBSDTapes} chapter of this manual
+for important FreeBSD information.) However, unlike previously, there
+is only one Storage definition in my server-dir.conf file:
+
+\footnotesize
+\begin{verbatim}
+Storage {
+ Name = "autochanger1" # Storage device for backing up
+ Address = Storage-server
+ SDPort = 9103
+ Password = "mysecretpassword"
+ Device = "autochanger1"
+ Media Type = AIT-1
+ Autochanger = yes
+}
+\end{verbatim}
+\normalsize
+
+Note that the Storage resource uses neither of the two addresses to
+the Storage daemon -- neither server.int.mydomain.tld nor
+firewall.mydomain.tld, but instead uses the address Storage-server.
+
+What is key is that in the internal net, Storage-server is resolved
+to server.int.mydomain.tld, either with an entry in /etc/hosts, or by
+creating and appropriate DNS entry, and on the external net (the Client
+machine), Storage-server is resolved to firewall.mydomain.tld.
+
+
+In addition to the above, I have two Client resources defined in
+server-dir.conf:
+
+\footnotesize
+\begin{verbatim}
+Client {
+ Name = private1-fd
+ Address = private1.int.mydomain.tld
+ FDPort = 9102
+ Catalog = MyCatalog
+ Password = "mysecretpassword" # password for FileDaemon
+}
+Client {
+ Name = public1-fd
+ Address = public1.mydomain.tld
+ FDPort = 9102
+ Catalog = MyCatalog
+ Password = "mysecretpassword" # password for FileDaemon
+}
+\end{verbatim}
+\normalsize
+
+And finally, to tie it all together, I have two Job resources defined in
+server-dir.conf:
+
+\footnotesize
+\begin{verbatim}
+Job {
+ Name = "Private1-Backup"
+ Type = Backup
+ Client = private1-fd
+ FileSet = "Private1"
+ Schedule = "WeeklyCycle"
+ Storage = "autochanger1-int"
+ Messages = Standard
+ Pool = "Weekly"
+ Write Bootstrap = "/var/db/bacula/Private1-Backup.bsr"
+ Priority = 12
+}
+Job {
+ Name = "Public1-Backup"
+ Type = Backup
+ Client = public1-fd
+ FileSet = "Public1"
+ Schedule = "WeeklyCycle"
+ Storage = "autochanger1-ext"
+ Messages = Standard
+ Pool = "Weekly"
+ Write Bootstrap = "/var/db/bacula/Public1-Backup.bsr"
+ Priority = 13
+}
+\end{verbatim}
+\normalsize
+
+It is important to notice that because the 'Private1-Backup' Job is intended
+to back up a machine on the internal network so it resolves Storage-server
+to contact the Storage daemon via the internal net.
+On the other hand, the 'Public1-Backup' Job is intended to
+back up a machine on the external network, so it resolves Storage-server
+to contact the Storage daemon via the external net.
+
+I have left the Pool, Catalog, Messages, FileSet, Schedule, and Director
+resources out of the above server-dir.conf examples because they are not
+pertinent to the discussion.
+
+\subsection{How Does It Work?}
+\index[general]{How Does It Work? }
+\index[general]{Work!How Does It }
+
+If I want to run a backup of private1.int.mydomain.tld and store that backup
+using server-sd then my understanding of the order of events is this:
+
+\begin{enumerate}
+\item I execute my Bacula 'console' command on server.int.mydomain.tld.
+\item console connects to server-dir.
+\item I tell console to 'run' backup Job 'Private1-Backup'.
+\item console relays this command to server-dir.
+\item server-dir connects to private1-fd at private1.int.mydomain.tld:9102
+\item server-dir tells private1-fd to start sending the files defined in the
+ 'Private1-Backup' Job's FileSet resource to the Storage resource
+ 'autochanger1', which we have defined in server-dir.conf as having the
+address:port of Storage-server, which is mapped by DNS to server.int.mydomain.tld.
+\item private1-fd connects to server.int.mydomain.tld:9103 and begins sending
+ files.
+ \end{enumerate}
+
+Alternatively, if I want to run a backup of public1.mydomain.tld and store
+that backup using server-sd then my understanding of the order of events is
+this:
+
+\begin{enumerate}
+\item I execute my Bacula 'console' command on server.int.mydomain.tld.
+\item console connects to server-dir.
+\item I tell console to 'run' backup Job 'Public1-Backup'.
+\item console relays this command to server-dir.
+\item server-dir connects, through the NAT'd firewall, to public1-fd at
+ public1.mydomain.tld:9102
+\item server-dir tells public1-fd to start sending the files defined in the
+ 'Public1-Backup' Job's FileSet resource to the Storage resource
+ 'autochanger1', which we have defined in server-dir.conf as having the
+ same address:port as above of Storage-server, but which on this machine
+ is resolved to firewall.mydomain.tld:9103.
+\item public1-fd connects to firewall.mydomain.tld:9103 and begins sending
+ files.
+ \end{enumerate}
+
+\subsection{Important Note}
+\index[general]{Important Note }
+\index[general]{Note!Important }
+
+In order for the above 'Public1-Backup' Job to succeed,

+\index[general]{Problems!Firewalls}
+Either a firewall or a router may decide to timeout and terminate
+open connections if they are not active for a short time. By Internet
+standards the period should be two hours, and should be indefinitely
+extended if KEEPALIVE is set as is the case by Bacula. If your firewall
+or router does not respect these rules, you may find Bacula connections
+terminated. In that case, the first thing to try is turning on the
+{\bf Heart Beat Interval} both in the File daemon and the Storage daemon
+and set an interval of say five minutes.
+
+Also, if you have denial of service rate limiting in your firewall, this
+too can cause Bacula disconnects since Bacula can at times use very high
+access rates. To avoid this, you should implement default accept
+rules for the Bacula ports involved before the rate limiting rules.
+
+Finally, if you have a Windows machine, it will most likely by default
+disallow connections to the Bacula Windows File daemon. See the
+Windows chapter of this manual for additional details.

+
+# Version Information:
+# 16-Feb-2005 -- Original Creation. Karl E. Cunningham
+# 14-Mar-2005 -- Clarified and Consolodated some of the code.
+# Changed to smoothly handle single and multiple indices.
+
+# Two LaTeX index formats are supported...
+# --- SINGLE INDEX ---
+# \usepackage{makeidx}
+# \makeindex
+# \index{entry1}
+# \index{entry2}
+# \index{entry3}
+# ...
+# \printindex
+#
+# --- MULTIPLE INDICES ---
+#
+# \usepackage{makeidx}
+# \usepackage{index}
+# \makeindex -- latex2html doesn't care but LaTeX does.
+# \newindex{ref1}{ext1}{ext2}{title1}
+# \newindex{ref2}{ext1}{ext2}{title2}
+# \newindex{ref3}{ext1}{ext2}{title3}
+# \index[ref1]{entry1}

+# \printindex
+# ___________________
+#
+# For the multiple-index style, each index is identified by the ref argument to \newindex, \index,
+# and \printindex. A default index is allowed, which is indicated by omitting the optional
+# argument. The default index does not require a \newindex command. As \index commands
+# are encountered, their entries are stored according
+# to the ref argument. When the \printindex command is encountered, the stored index
+# entries for that argument are retrieved and printed. The title for each index is taken
+# from the last argument in the \newindex command.
+# While processing \index and \printindex commands, if no argument is given the index entries
+# are built into a default index. The title of the default index is simply "Index".
+# This makes the difference between single- and multiple-index processing trivial.
+#
+# Another method can be used by omitting the \printindex command and just using \include to
+# pull in index files created by the makeindex program. These files will start with
+# \begin{theindex}. This command is used to determine where to print the index. Using this
+# approach, the indices will be output in the same order as the newindex commands were
+# originally found (see below). Using a combination of \printindex and \include{indexfile} has not
+# been tested and may produce undesireable results.
+#
+# The index data are stored in a hash for later sorting and output. As \printindex
+# commands are handled, the order in which they were found in the tex filea is saved,
+# associated with the ref argument to \printindex.
+#
+# We use the original %index hash to store the index data into. We append a \002 followed by the
+# name of the index to isolate the entries in different indices from each other. This is necessary
+# so that different indices can have entries with the same name. For the default index, the \002 is
+# appended without the name.
+#
+# Since the index order in the output cannot be determined if the \include{indexfile}
+# command is used, the order will be assumed from the order in which the \newindex
+# commands were originally seen in the TeX files. This order is saved as well as the
+# order determined from any printindex{ref} commands. If \printindex commnads are used
+# to specify the index output, that order will be used. If the \include{idxfile} command
+# is used, the order of the original newindex commands will be used. In this case the
+# default index will be printed last since it doesn't have a corresponding \newindex
+# command and its order cannot be determined. Mixing \printindex and \include{idxfile}
+# commands in the same file is likely to produce less than satisfactory results.
+#
+#
+# The hash containing index data is named %indices. It contains the following data:
+#{
+# 'title' => {
+# $ref1 => $indextitle ,
+# $ref2 => $indextitle ,
+# ...
+# },
+# 'newcmdorder' => [ ref1, ref2, ..., * ], # asterisk indicates the position of the default index.
+# 'printindorder' => [ ref1, ref2, ..., * ], # asterisk indicates the position of the default index.

+\chapter{What To Do When Bacula Crashes (Kaboom)}
+\label{KaboomChapter}
+\index[general]{Kaboom!What To Do When Bacula Crashes }
+\index[general]{What To Do When Bacula Crashes (Kaboom) }
+
+If you are running on a Linux system, and you have a set of working
+configuration files, it is very unlikely that {\bf Bacula} will crash. As with
+all software, however, it is inevitable that someday, it may crash,
+particularly if you are running on another operating system or using a new or
+unusual feature.
+
+This chapter explains what you should do if one of the three {\bf Bacula}
+daemons (Director, File, Storage) crashes. When we speak of crashing, we
+mean that the daemon terminates abnormally because of an error. There are
+many cases where Bacula detects errors (such as PIPE errors) and will fail
+a job. These are not considered crashes. In addition, under certain
+conditions, Bacula will detect a fatal in the configuration, such as
+lack of permission to read/write the working directory. In that case,
+Bacula will force itself to crash with a SEGFAULT. However, before
+crashing, Bacula will normally display a message indicating why.
+For more details, please read on.
+
+
+\section{Traceback}
+\index[general]{Traceback}
+
+Each of the three Bacula daemons has a built-in exception handler which, in
+case of an error, will attempt to produce a traceback. If successful the
+traceback will be emailed to you.
+
+For this to work, you need to ensure that a few things are setup correctly on
+your system:
+
+\begin{enumerate}
+\item You must have a version of Bacula built with debug information turned
+ on and not stripped of debugging symbols.
+
+\item You must have an installed copy of {\bf gdb} (the GNU debugger), and it
+ must be on {\bf Bacula's} path. On some systems such as Solaris, {\bf
+ gdb} may be replaced by {\bf dbx}.
+
+\item The Bacula installed script file {\bf btraceback} must be in the same
+ directory as the daemon which dies, and it must be marked as executable.
+
+\item The script file {\bf btraceback.gdb} must have the correct path to it
+ specified in the {\bf btraceback} file.
+
+\item You must have a {\bf mail} program which is on {\bf Bacula's} path.
+ By default, this {\bf mail} program is set to {\bf bsmtp}, so it must
+ be correctly configured.
+
+\item If you run either the Director or Storage daemon under a non-root
+ userid, you will most likely need to modify the {\bf btraceback} file
+ to do something like {\bf sudo} (raise to root priority) for the
+ call to {\bf gdb} so that it has the proper permissions to debug
+ Bacula.
+\end{enumerate}
+
+If all the above conditions are met, the daemon that crashes will produce a
+traceback report and email it to you. If the above conditions are not true,
+you can either run the debugger by hand as described below, or you may be able
+to correct the problems by editing the {\bf btraceback} file. I recommend not
+spending too much time on trying to get the traceback to work as it can be
+very difficult.
+
+The changes that might be needed are to add a correct path to the {\bf gdb}
+program, correct the path to the {\bf btraceback.gdb} file, change the {\bf
+mail} program or its path, or change your email address. The key line in the
+{\bf btraceback} file is:
+
+\footnotesize
+\begin{verbatim}
+gdb -quiet -batch -x /home/kern/bacula/bin/btraceback.gdb \
+ $1 $2 2>\&1 | bsmtp -s "Bacula traceback" your-address@xxx.com
+\end{verbatim}
+\normalsize
+
+Since each daemon has the same traceback code, a single btraceback file is
+sufficient if you are running more than one daemon on a machine.
+
+\section{Testing The Traceback}
+\index[general]{Traceback!Testing The }
+\index[general]{Testing The Traceback }
+
+To "manually" test the traceback feature, you simply start {\bf Bacula} then
+obtain the {\bf PID} of the main daemon thread (there are multiple threads).
+The output produced here will look different depending on what OS and what
+version of the kernel you are running.
+Unfortunately, the output had to be split to fit on this page:
+
+\footnotesize
+\begin{verbatim}
+[kern@rufus kern]$ ps fax --columns 132 | grep bacula-dir
+ 2103 ? S 0:00 /home/kern/bacula/k/src/dird/bacula-dir -c
+ /home/kern/bacula/k/src/dird/dird.conf
+ 2104 ? S 0:00 \_ /home/kern/bacula/k/src/dird/bacula-dir -c
+ /home/kern/bacula/k/src/dird/dird.conf
+ 2106 ? S 0:00 \_ /home/kern/bacula/k/src/dird/bacula-dir -c
+ /home/kern/bacula/k/src/dird/dird.conf
+ 2105 ? S 0:00 \_ /home/kern/bacula/k/src/dird/bacula-dir -c
+ /home/kern/bacula/k/src/dird/dird.conf
+\end{verbatim}
+\normalsize
+
+which in this case is 2103. Then while Bacula is running, you call the program
+giving it the path to the Bacula executable and the {\bf PID}. In this case,
+it is:
+
+\footnotesize
+\begin{verbatim}
+./btraceback /home/kern/bacula/k/src/dird 2103
+\end{verbatim}
+\normalsize
+
+It should produce an email showing you the current state of the daemon (in
+this case the Director), and then exit leaving {\bf Bacula} running as if
+nothing happened. If this is not the case, you will need to correct the
+problem by modifying the {\bf btraceback} script.
+
+Typical problems might be that {\bf gdb} or {\bf dbx} for Solaris is not on
+the default path. Fix this by specifying the full path to it in the {\bf
+btraceback} file. Another common problem is that you haven't modified the
+script so that the {\bf bsmtp} program has an appropriate smtp server or
+the proper syntax for your smtp server. If you use the {\bf mail} program
+and it is not on the default path, it will also fail. On some systems, it
+is preferable to use {\bf Mail} rather than {\bf mail}.
+
+\section{Getting A Traceback On Other Systems}
+\index[general]{Getting A Traceback On Other Systems}
+\index[general]{Systems!Getting A Traceback On Other}
+
+It should be possible to produce a similar traceback on systems other than
+Linux, either using {\bf gdb} or some other debugger. Solaris with {\bf dbx}
+loaded works quite fine. On other systems, you will need to modify the {\bf
+btraceback} program to invoke the correct debugger, and possibly correct the
+{\bf btraceback.gdb} script to have appropriate commands for your debugger. If
+anyone succeeds in making this work with another debugger, please send us a
+copy of what you modified. Please keep in mind that for any debugger to
+work, it will most likely need to run as root, so you may need to modify
+the {\bf btraceback} script accordingly.
+
+\label{ManuallyDebugging}
+\section{Manually Running Bacula Under The Debugger}
+\index[general]{Manually Running Bacula Under The Debugger}
+\index[general]{Debugger!Manually Running Bacula Under The}
+
+If for some reason you cannot get the automatic traceback, or if you want to
+interactively examine the variable contents after a crash, you can run Bacula
+under the debugger. Assuming you want to run the Storage daemon under the
+debugger (the technique is the same for the other daemons, only the name
+changes), you would do the following:
+
+\begin{enumerate}
+\item Start the Director and the File daemon. If the Storage daemon also
+ starts, you will need to find its PID as shown above (ps fax | grep
+ bacula-sd) and kill it with a command like the following:
+
+\footnotesize
+\begin{verbatim}
+ kill -15 PID
+\end{verbatim}
+\normalsize
+
+where you replace {\bf PID} by the actual value.
+
+\item At this point, the Director and the File daemon should be running but
+ the Storage daemon should not.
+
+\item cd to the directory containing the Storage daemon
+
+\item Start the Storage daemon under the debugger:
+
+ \footnotesize
+\begin{verbatim}
+ gdb ./bacula-sd
+\end{verbatim}
+\normalsize
+
+\item Run the Storage daemon:
+
+ \footnotesize
+\begin{verbatim}
+ run -s -f -c ./bacula-sd.conf
+\end{verbatim}
+\normalsize
+
+You may replace the {\bf ./bacula-sd.conf} with the full path to the Storage
+daemon's configuration file.
+
+\item At this point, Bacula will be fully operational.
+
+\item In another shell command window, start the Console program and do what
+ is necessary to cause Bacula to die.
+
+\item When Bacula crashes, the {\bf gdb} shell window will become active and
+ {\bf gdb} will show you the error that occurred.
+
+\item To get a general traceback of all threads, issue the following command:
+
+
+\footnotesize
+\begin{verbatim}
+ thread apply all bt
+\end{verbatim}
+\normalsize
+
+After that you can issue any debugging command.
+\end{enumerate}
+
+\section{Getting Debug Output from Bacula}
+\index[general]{Getting Debug Output from Bacula }
+Each of the daemons normally has debug compiled into the program, but
+disabled. There are two ways to enable the debug output. One is to add the
+{\bf -d nnn} option on the command line when starting the debugger. The {\bf
+nnn} is the debug level, and generally anything between 50 and 200 is
+reasonable. The higher the number, the more output is produced. The output is
+written to standard output.
+
+The second way of getting debug output is to dynamically turn it on using the
+Console using the {\bf setdebug} command. The full syntax of the command is:
+
+\footnotesize
+\begin{verbatim}
+ setdebug level=nnn client=client-name storage=storage-name dir
+\end{verbatim}
+\normalsize
+
+If none of the options are given, the command will prompt you. You can
+selectively turn on/off debugging in any or all the daemons (i.e. it is not
+necessary to specify all the components of the above command).

+\section{Answers}
+\index[general]{Answers }
+
+\begin{enumerate}
+\item
+ \label{faq1}
+ {\bf How do I build Bacula for platform xxx?}
+ The bacula spec file contains defines to build for several platforms:
+ Red Hat 7.x (rh7), Red Hat 8.0 (rh8), Red Hat 9 (rh9), Fedora Core (fc1,
+ fc3, fc4, fc5, fc6, fc7), Whitebox Enterprise Linux 3.0 (wb3), Red Hat Enterprise Linux
+ (rhel3, rhel4, rhel5), Mandrake 10.x (mdk), Mandriva 2006.x (mdv) CentOS (centos3, centos4, centos5)
+ Scientific Linux (sl3, sl4, sl5) and SuSE (su9, su10, su102, su103). The package build is controlled by a mandatory define set at the beginning of the file. These defines basically just control the dependency information that gets coded into the finished rpm package as well
+ as any special configure options required. The platform define may be edited
+ in the spec file directly (by default all defines are set to 0 or "not set").
+ For example, to build the Red Hat 7.x package find the line in the spec file
+ which reads
+
+\footnotesize
+\begin{verbatim}
+ %define rh7 0
+
+\end{verbatim}
+\normalsize
+
+and edit it to read
+
+\footnotesize
+\begin{verbatim}
+ %define rh7 1
+
+\end{verbatim}
+\normalsize
+
+Alternately you may pass the define on the command line when calling rpmbuild:
+
+
+\footnotesize
+\begin{verbatim}
+ rpmbuild -ba --define "build_rh7 1" bacula.spec
+ rpmbuild --rebuild --define build_rh7 1" bacula-x.x.x-x.src.rpm
+
+\end{verbatim}
+\normalsize
+
+\item
+ \label{faq2}
+ {\bf How do I control which database support gets built?}
+ Another mandatory build define controls which database support is compiled,
+ one of build\_sqlite, build\_mysql or build\_postgresql. To get the MySQL
+ package and support either set the
+
+\footnotesize
+\begin{verbatim}
+ %define mysql 0
+ OR
+ %define mysql4 0
+ OR
+ %define mysql5 0
+
+\end{verbatim}
+\normalsize
+
+to
+
+\footnotesize
+\begin{verbatim}
+ %define mysql 1
+ OR
+ %define mysql4 1
+ OR
+ %define mysql5 1
+
+\end{verbatim}
+\normalsize
+
+in the spec file directly or pass it to rpmbuild on the command line:
+
+\footnotesize
+\begin{verbatim}
+ rpmbuild -ba --define "build_rh7 1" --define "build_mysql 1" bacula.spec
+ rpmbuild -ba --define "build_rh7 1" --define "build_mysql4 1" bacula.spec
+ rpmbuild -ba --define "build_rh7 1" --define "build_mysql5 1" bacula.spec
+
+\end{verbatim}
+\normalsize
+
+\item
+ \label{faq3}
+ {\bf What other defines are used?}
+ Three other building defines of note are the depkgs\_version, docs\_version and
+ \_rescuever identifiers. These two defines are set with each release and must
+ match the version of those sources that are being used to build the packages.

+\item
+ \label{faq4}
+ {\bf I'm getting errors about not having permission when I try to build the
+ packages. Do I need to be root?}
+ No, you do not need to be root and, in fact, it is better practice to
+ build rpm packages as a non-root user. Bacula packages are designed to
+ be built by a regular user but you must make a few changes on your
+ system to do this. If you are building on your own system then the
+ simplest method is to add write permissions for all to the build
+ directory (/usr/src/redhat/, /usr/src/RPM or /usr/src/packages).
+ To accomplish this, execute the following command as root:
+
+\footnotesize
+\begin{verbatim}
+ chmod -R 777 /usr/src/redhat
+ chmod -R 777 /usr/src/RPM
+ chmod -R 777 /usr/src/packages
+
+\end{verbatim}
+\normalsize
+
+If you are working on a shared system where you can not use the method
+above then you need to recreate the appropriate above directory tree with all
+of its subdirectories inside your home directory. Then create a file named
+
+{\tt .rpmmacros}
+
+in your home directory (or edit the file if it already exists)
+and add the following line:
+
+\footnotesize
+\begin{verbatim}
+ %_topdir /home/myuser/redhat
+ %_tmppath /tmp
+
+\end{verbatim}
+\normalsize
+
+Another handy directive for the .rpmmacros file if you wish to suppress the
+creation of debug rpm packages is:
+
+\footnotesize
+\begin{verbatim}
+ %debug_package %{nil}
+
+\end{verbatim}
+
+\normalsize
+
+\item
+ \label{faq5}
+ {\bf I'm building my own rpms but on all platforms and compiles I get an
+ unresolved dependency for something called /usr/afsws/bin/pagsh.} This
+ is a shell from the OpenAFS (Andrew File System). If you are seeing
+ this then you chose to include the docs/examples directory in your
+ package. One of the example scripts in this directory is a pagsh
+ script. Rpmbuild, when scanning for dependencies, looks at the shebang
+ line of all packaged scripts in addition to checking shared libraries.
+ To avoid this do not package the examples directory. If you are seeing this
+ problem you are building a very old bacula package as the examples have been
+ removed from the doc packaging.
+
+\item
+ \label{faq6}
+ {\bf I'm building my own rpms because you don't publish for my platform.
+ Can I get my packages released to sourceforge for other people to use?} Yes,
+ contributions from users are accepted and appreciated. Please examine the
+ directory platforms/contrib-rpm in the source code for further information.
+
+\item
+ \label{faq7}
+ {\bf Is there an easier way than sorting out all these command line options?} Yes,
+ there is a gui wizard shell script which you can use to rebuild the src rpm package.
+ Look in the source archive for platforms/contrib-rpm/rpm\_wizard.sh. This script will
+ allow you to specify build options using GNOME dialog screens. It requires zenity.
+
+\item
+ \label{faq8}
+ {\bf I just upgraded from 1.36.x to 1.38.x and now my director daemon
+won't start. It appears to start but dies silently and I get a "connection
+refused" error when starting the console. What is wrong?} Beginning with
+1.38 the rpm packages are configured to run the director and storage
+daemons as a non-root user. The file daemon runs as user root and group
+bacula, the storage daemon as user bacula and group disk, and the director
+as user bacula and group bacula. If you are upgrading you will need to
+change some file permissions for things to work. Execute the following
+commands as root:
+
+\footnotesize
+\begin{verbatim}
+ chown bacula.bacula /var/bacula/*
+ chown root.bacula /var/bacula/bacula-fd.9102.state
+ chown bacula.disk /var/bacula/bacula-sd.9103.state
+
+\end{verbatim}
+\normalsize
+
+Further, if you are using File storage volumes rather than tapes those
+files will also need to have ownership set to user bacula and group bacula.
+
+\item
+ \label{faq9}
+ {\bf There are a lot of rpm packages. Which packages do I need for
+what?} For a bacula server you need to select the packsge based upon your
+preferred catalog database: one of bacula-mysql, bacula-postgresql or
+bacula-sqlite. If your system does not provide an mtx package you also
+need bacula-mtx to satisfy that dependancy. For a client machine you need
+only install bacula-client. Optionally, for either server or client
+machines, you may install a graphical console bacula-gconsole and/or
+bacula-wxconsole. The Bacula Administration Tool is installed with the
+bacula-bat package. One last package, bacula-updatedb is required only when
+upgrading a server more than one database revision level.
+
+
+
+\item {\bf Support for RHEL3/4/5, CentOS 3/4/5, Scientific Linux 3/4/5 and x86\_64}
+ The examples below show
+ explicit build support for RHEL4 and CentOS 4. Build support
+ for x86\_64 has also been added.

+\section{RPM Install Problems}
+\index[general]{RPM Install Problems}
+In general the RPMs, once properly built should install correctly.
+However, when attempting to run the daemons, a number of problems
+can occur:
+\begin{itemize}
+\item [Wrong /var/bacula Permissions]
+ By default, the Director and Storage daemon do not run with
+ root permission. If the /var/bacula is owned by root, then it
+ is possible that the Director and the Storage daemon will not
+ be able to access this directory, which is used as the Working
+ Directory. To fix this, the easiest thing to do is:
+\begin{verbatim}
+ chown bacula:bacula /var/bacula
+\end{verbatim}
+ Note: as of 1.38.8 /var/bacula is installed root:bacula with
+ permissions 770.
+\item [The Storage daemon cannot Access the Tape drive]
+ This can happen in some older RPM releases where the Storage
+ daemon ran under userid bacula, group bacula. There are two
+ ways of fixing this: the best is to modify the /etc/init.d/bacula-sd
+ file so that it starts the Storage daemon with group "disk".
+ The second way to fix the problem is to change the permissions
+ of your tape drive (usually /dev/nst0) so that Bacula can access it.
+ You will probably need to change the permissions of the SCSI control
+ device as well, which is usually /dev/sg0. The exact names depend
+ on your configuration, please see the Tape Testing chapter for
+ more information on devices.

+\chapter{Testing Your Tape Drive With Bacula}
+\label{TapeTestingChapter}
+\index[general]{Testing Your Tape Drive With Bacula}
+
+This chapter is concerned with testing and configuring your tape drive to make
+sure that it will work properly with Bacula using the {\bf btape} program.
+\label{summary}
+
+\section{Get Your Tape Drive Working}
+
+In general, you should follow the following steps to get your tape drive to
+work with Bacula. Start with a tape mounted in your drive. If you have an
+autochanger, load a tape into the drive. We use {\bf /dev/nst0} as the tape
+drive name, you will need to adapt it according to your system.
+
+Do not proceed to the next item until you have succeeded with the previous
+one.
+
+\begin{enumerate}
+\item Make sure that Bacula (the Storage daemon) is not running
+ or that you have {\bf unmount}ed the drive you will use
+ for testing.
+
+\item Use tar to write to, then read from your drive:
+
+ \footnotesize
+\begin{verbatim}
+ mt -f /dev/nst0 rewind
+ tar cvf /dev/nst0 .
+ mt -f /dev/nst0 rewind
+ tar tvf /dev/nst0
+
+\end{verbatim}
+\normalsize
+
+\item Make sure you have a valid and correct Device resource corresponding
+ to your drive. For Linux users, generally, the default one works. For
+ FreeBSD users, there are two possible Device configurations (see below).
+ For other drives and/or OSes, you will need to first ensure that your
+ system tape modes are properly setup (see below), then possibly modify
+ you Device resource depending on the output from the btape program (next
+ item). When doing this, you should consult the \ilink{Storage Daemon
+ Configuration}{StoredConfChapter} of this manual.
+
+\item If you are using a Fibre Channel to connect your tape drive to
+ Bacula, please be sure to disable any caching in the NSR (network
+ storage router, which is a Fibre Channel to SCSI converter).
+
+\item Run the btape {\bf test} command:
+
+ \footnotesize
+\begin{verbatim}
+ ./btape -c bacula-sd.conf /dev/nst0
+ test
+
+\end{verbatim}
+\normalsize
+
+ It isn't necessary to run the autochanger part of the test at this time,
+ but do not go past this point until the basic test succeeds. If you do
+ have an autochanger, please be sure to read the \ilink{Autochanger
+ chapter}{AutochangersChapter} of this manual.
+
+\item Run the btape {\bf fill} command, preferably with two volumes. This
+ can take a long time. If you have an autochanger and it is configured, Bacula
+ will automatically use it. If you do not have it configured, you can manually
+ issue the appropriate {\bf mtx} command, or press the autochanger buttons to
+ change the tape when requested to do so.
+
+\item FreeBSD users, if you have a pre-5.0 system run the {\bf tapetest}
+ program, and make sure your system is patched if necessary. The tapetest
+ program can be found in the platform/freebsd directory. The instructions
+ for its use are at the top of the file.
+
+\item Run Bacula, and backup a reasonably small directory, say 60
+ Megabytes. Do three successive backups of this directory.
+
+\item Stop Bacula, then restart it. Do another full backup of the same
+ directory. Then stop and restart Bacula.
+
+\item Do a restore of the directory backed up, by entering the following
+ restore command, being careful to restore it to an alternate location:
+
+
+\footnotesize
+\begin{verbatim}
+ restore select all done
+ yes
+
+\end{verbatim}
+\normalsize
+
+ Do a {\bf diff} on the restored directory to ensure it is identical to the
+ original directory. If you are going to backup multiple different systems
+ (Linux, Windows, Mac, Solaris, FreeBSD, ...), be sure you test the restore
+ on each system type.
+
+\item If you have an autochanger, you should now go back to the btape program
+ and run the autochanger test:
+
+\footnotesize
+\begin{verbatim}
+ ./btape -c bacula-sd.conf /dev/nst0
+ auto
+
+\end{verbatim}
+\normalsize
+
+ Adjust your autochanger as necessary to ensure that it works correctly. See
+ the Autochanger chapter of this manual for a complete discussion of testing
+ your autochanger.
+
+\item We strongly recommend that you use a dedicated SCSI
+ controller for your tape drives. Scanners are known to induce
+ serious problems with the SCSI bus, causing it to reset. If the
+ SCSI bus is reset while Bacula has the tape drive open, it will
+ most likely be fatal to your tape since the drive will rewind.
+ These kinds of problems show up in the system log. For example,
+ the following was most likely caused by a scanner:
+
+\footnotesize
+\begin{verbatim}
+Feb 14 17:29:55 epohost kernel: (scsi0:A:2:0): No or incomplete CDB sent to device.
+Feb 14 17:29:55 epohost kernel: scsi0: Issued Channel A Bus Reset. 1 SCBs aborted
+\end{verbatim}
+\normalsize
+
+\end{enumerate}
+
+If you have reached this point, you stand a good chance of having everything
+work. If you get into trouble at any point, {\bf carefully} read the
+documentation given below. If you cannot get past some point, ask the {\bf
+bacula-users} email list, but specify which of the steps you have successfully
+completed. In particular, you may want to look at the
+\ilink{ Tips for Resolving Problems}{problems1} section below.
+
+
+\label{NoTapeInDrive}
+\subsection{Problems When no Tape in Drive}
+\index[general]{Problems When no Tape in Drive}
+When Bacula was first written the Linux 2.4 kernel permitted opening the
+drive whether or not there was a tape in the drive. Thus the Bacula code is
+based on the concept that if the drive cannot be opened, there is a serious
+problem, and the job is failed.
+
+With version 2.6 of the Linux kernel, if there is no tape in the drive, the
+OS will wait two minutes (default) and then return a failure, and consequently,
+Bacula version 1.36 and below will fail the job. This is important to keep
+in mind, because if you use an option such as {\bf Offline on Unmount =
+yes}, there will be a point when there is no tape in the drive, and if
+another job starts or if Bacula asks the operator to mount a tape, when
+Bacula attempts to open the drive (about a 20 minute delay), it will fail
+and Bacula will fail the job.
+
+In version 1.38.x, the Bacula code partially gets around this problem -- at
+least in the initial open of the drive. However, functions like Polling
+the drive do not work correctly if there is no tape in the drive.
+Providing you do not use {\bf Offline on Unmount = yes}, you should not
+experience job failures as mentioned above. If you do experience such
+failures, you can also increase the {\bf Maximum Open Wait} time interval,
+which will give you more time to mount the next tape before the job is
+failed.
+
+\subsection{Specifying the Configuration File}
+\index[general]{File!Specifying the Configuration}
+\index[general]{Specifying the Configuration File}
+
+Starting with version 1.27, each of the tape utility programs including the
+{\bf btape} program requires a valid Storage daemon configuration file
+(actually, the only part of the configuration file that {\bf btape} needs is
+the {\bf Device} resource definitions). This permits {\bf btape} to find the
+configuration parameters for your archive device (generally a tape drive).
+Without those parameters, the testing and utility programs do not know how to
+properly read and write your drive. By default, they use {\bf bacula-sd.conf}
+in the current directory, but you may specify a different configuration file
+using the {\bf -c} option.
+
+\subsection{Specifying a Device Name For a Tape}
+\index[general]{Tape!Specifying a Device Name For a}
+\index[general]{Specifying a Device Name For a Tape}
+
+{\bf btape} {\bf device-name} where the Volume can be found. In the case of a
+tape, this is the physical device name such as {\bf /dev/nst0} or {\bf
+/dev/rmt/0ubn} depending on your system that you specify on the Archive Device
+directive. For the program to work, it must find the identical name in the
+Device resource of the configuration file. If the name is not found in the
+list of physical names, the utility program will compare the name you entered
+to the Device names (rather than the Archive device names).
+
+When specifying a tape device, it is preferable that the "non-rewind"
+variant of the device file name be given. In addition, on systems such as
+Sun, which have multiple tape access methods, you must be sure to specify
+to use Berkeley I/O conventions with the device. The
+{\bf b} in the Solaris (Sun) archive specification {\bf /dev/rmt/0mbn} is
+what is needed in this case. Bacula does not support SysV tape drive
+behavior.
+
+See below for specifying Volume names.
+
+\subsection{Specifying a Device Name For a File}
+\index[general]{File!Specifying a Device Name For a}
+\index[general]{Specifying a Device Name For a File}
+
+If you are attempting to read or write an archive file rather than a tape, the
+{\bf device-name} should be the full path to the archive location including
+the filename. The filename (last part of the specification) will be stripped
+and used as the Volume name, and the path (first part before the filename)
+must have the same entry in the configuration file. So, the path is equivalent
+to the archive device name, and the filename is equivalent to the volume name.
+
+
+\section{btape}
+\label{btape1}
+\index[general]{Btape}
+
+This program permits a number of elementary tape operations via a tty command
+interface. The {\bf test} command, described below, can be very useful for
+testing tape drive compatibility problems. Aside from initial testing of tape
+drive compatibility with {\bf Bacula}, {\bf btape} will be mostly used by
+developers writing new tape drivers.
+
+{\bf btape} can be dangerous to use with existing {\bf Bacula} tapes because
+it will relabel a tape or write on the tape if so requested regardless of
+whether or not the tape contains valuable data, so please be careful and use
+it only on blank tapes.
+
+To work properly, {\bf btape} needs to read the Storage daemon's configuration
+file. As a default, it will look for {\bf bacula-sd.conf} in the current
+directory. If your configuration file is elsewhere, please use the {\bf -c}
+option to specify where.
+
+The physical device name or the Device resource name must be specified on the
+command line, and this same device name must be present in the Storage
+daemon's configuration file read by {\bf btape}
+
+\footnotesize
+\begin{verbatim}
+Usage: btape [options] device_name
+ -b <file> specify bootstrap file
+ -c <file> set configuration file to file
+ -d <nn> set debug level to nn
+ -p proceed inspite of I/O errors
+ -s turn off signals
+ -v be verbose
+ -? print this message.
+\end{verbatim}
+\normalsize
+
+\subsection{Using btape to Verify your Tape Drive}
+\index[general]{Using btape to Verify your Tape Drive}
+\index[general]{Drive!Using btape to Verify your Tape}
+
+An important reason for this program is to ensure that a Storage daemon
+configuration file is defined so that Bacula will correctly read and write
+tapes.
+
+It is highly recommended that you run the {\bf test} command before running
+your first Bacula job to ensure that the parameters you have defined for your
+storage device (tape drive) will permit {\bf Bacula} to function properly. You
+only need to mount a blank tape, enter the command, and the output should be
+reasonably self explanatory. For example:
+
+\footnotesize
+\begin{verbatim}
+(ensure that Bacula is not running)
+./btape -c /usr/bin/bacula/bacula-sd.conf /dev/nst0
+\end{verbatim}
+\normalsize
+
+The output will be:
+
+\footnotesize
+\begin{verbatim}
+Tape block granularity is 1024 bytes.
+btape: btape.c:376 Using device: /dev/nst0
+*
+\end{verbatim}
+\normalsize
+
+Enter the test command:
+
+\footnotesize
+\begin{verbatim}
+test
+\end{verbatim}
+\normalsize
+
+The output produced should be something similar to the following: I've cut the
+listing short because it is frequently updated to have new tests.
+
+\footnotesize
+\begin{verbatim}
+=== Append files test ===
+This test is essential to Bacula.
+I'm going to write one record in file 0,
+ two records in file 1,

+btape: btape.c:427 Moved to end of media
+We should be in file 3. I am at file 3. This is correct!
+Now the important part, I am going to attempt to append to the tape.
+...
+=== End Append files test ===
+\end{verbatim}
+\normalsize
+
+If you do not successfully complete the above test, please resolve the
+problem(s) before attempting to use {\bf Bacula}. Depending on your tape
+drive, the test may recommend that you add certain records to your
+configuration. We strongly recommend that you do so and then re-run the above
+test to insure it works the first time.
+
+Some of the suggestions it provides for resolving the problems may or may not
+be useful. If at all possible avoid using fixed blocking. If the test suddenly
+starts to print a long series of:
+
+\footnotesize
+\begin{verbatim}
+Got EOF on tape.
+Got EOF on tape.
+...
+\end{verbatim}
+\normalsize
+
+then almost certainly, you are running your drive in fixed block mode rather
+than variable block mode. See below for more help of resolving fix
+versus variable block problems.
+
+It is also possible that you have your drive
+set in SysV tape drive mode. The drive must use BSD tape conventions.
+See the section above on setting your {\bf Archive device} correctly.
+
+For FreeBSD users, please see the notes below for doing further testing of
+your tape drive.

+would normally reference them as /dev/nst0 ... /dev/nst2. Not also,
+there are two different autochangers identified as "mediumx OVERLAND LXB".
+They can be addressed via their /dev/sgN designation, which can be
+obtained by counting from the beginning as 0 to each changer. In the
+above case, the two changers are located on /dev/sg3 and /dev/sg5. The one
+at /dev/sg3, controls drives /dev/nst0 and /dev/nst1; and the one at
+/dev/sg5 controles drive /dev/nst2.
+
+If you do not have the {\bf lsscsi} command, you can obtain the same
+information as follows:

+\begin{verbatim}

+
+For the above example with the three drives and two autochangers,
+I get:

+The above represents first an autochanger and second a simple

+\subsection{Bacula Saves But Cannot Restore Files}

+\index[general]{Bacula Saves But Cannot Restore Files}
+
+If you are getting error messages such as:
+
+\footnotesize
+\begin{verbatim}
+Volume data error at 0:1! Wanted block-id: "BB02", got "". Buffer discarded
+\end{verbatim}
+\normalsize
+
+It is very likely that Bacula has tried to do block positioning and ended up
+at an invalid block. This can happen if your tape drive is in fixed block mode
+while Bacula's default is variable blocks. Note that in such cases, Bacula is
+perfectly able to write to your Volumes (tapes), but cannot position to read
+them.
+
+There are two possible solutions.
+
+\begin{enumerate}
+\item The first and best is to always ensure that your drive is in variable
+ block mode. Note, it can switch back to fixed block mode on a reboot or if
+ another program uses the drive. So on such systems you need to modify the
+ Bacula startup files to explicitly set:
+
+\footnotesize
+\begin{verbatim}
+mt -f /dev/nst0 defblksize 0
+\end{verbatim}
+\normalsize
+
+or whatever is appropriate on your system. Note, if you are running a Linux
+system, and the above command does not work, it is most likely because you
+have not loaded the appropriate {\bf mt} package, which is often called
+{\bf mt\_st}, but may differ according to your distribution.
+
+\item The second possibility, especially, if Bacula wrote while the drive was
+ in fixed block mode, is to turn off block positioning in Bacula. This is done
+ by adding:
+
+\footnotesize
+\begin{verbatim}
+Block Positioning = no
+\end{verbatim}
+\normalsize
+
+to the Device resource. This is not the recommended procedure because it can
+enormously slow down recovery of files, but it may help where all else
+fails. This directive is available in version 1.35.5 or later (and not yet
+tested).
+\end{enumerate}
+
+If you are getting error messages such as:
+\footnotesize
+\begin{verbatim}
+Volume data error at 0:0!
+Block checksum mismatch in block=0 len=32625 calc=345678 blk=123456
+\end{verbatim}
+\normalsize
+
+You are getting tape read errors, and this is most likely due to
+one of the following things:
+\begin{enumerate}
+\item An old or bad tape.
+\item A dirty drive that needs cleaning (particularly for DDS drives).
+\item A loose SCSI cable.
+\item Old firmware in your drive. Make sure you have the latest firmware
+ loaded.
+\item Computer memory errors.
+\item Over-clocking your CPU.
+\item A bad SCSI card.
+\end{enumerate}

+
+If you get an error message such as:
+
+\footnotesize
+\begin{verbatim}
+dev open failed: dev.c:265 stored: unable to open
+device /dev/nst0:> ERR=No such device or address
+\end{verbatim}
+\normalsize
+
+the first time you run a job, it is most likely due to the fact that you
+specified the incorrect device name on your {\bf Archive Device}.
+
+If Bacula works fine with your drive, then all off a sudden you get error
+messages similar to the one shown above, it is quite possible that your driver
+module is being removed because the kernel deems it idle. This is done via
+{\bf crontab} with the use of {\bf rmmod -a}. To fix the problem, you can
+remove this entry from {\bf crontab}, or you can manually {\bf modprob} your
+driver module (or add it to the local startup script). Thanks to Alan Brown
+for this tip.
+\label{IncorrectFiles}
+
+\subsection{Incorrect File Number}
+\index[general]{Number!Incorrect File}
+\index[general]{Incorrect File Number}
+
+When Bacula moves to the end of the medium, it normally uses the {\bf
+ioctl(MTEOM)} function. Then Bacula uses the {\bf ioctl(MTIOCGET)} function to
+retrieve the current file position from the {\bf mt\_fileno} field. Some SCSI
+tape drivers will use a fast means of seeking to the end of the medium and in
+doing so, they will not know the current file position and hence return a {\bf
+-1}. As a consequence, if you get {\bf "This is NOT correct!"} in the
+positioning tests, this may be the cause. You must correct this condition in
+order for Bacula to work.
+
+There are two possible solutions to the above problem of incorrect file
+number:
+
+\begin{itemize}
+\item Figure out how to configure your SCSI driver to keep track of the file
+ position during the MTEOM request. This is the preferred solution.
+\item Modify the {\bf Device} resource of your {\bf bacula-sd.conf} file to
+ include:
+
+\footnotesize
+\begin{verbatim}
+Hardware End of File = no
+\end{verbatim}
+\normalsize
+
+This will cause Bacula to use the MTFSF request to seek to the end of the
+medium, and Bacula will keep track of the file number itself.
+\end{itemize}
+
+\label{IncorrectBlocks}
+\subsection{Incorrect Number of Blocks or Positioning Errors}
+\index[general]{Testing!Incorrect Number of Blocks or Positioning Errors}
+\index[general]{Incorrect Number of Blocks or Positioning Errors}
+
+{\bf Bacula's} preferred method of working with tape drives (sequential
+devices) is to run in variable block mode, and this is what is set by default.
+You should first ensure that your tape drive is set for variable block mode
+(see below).
+
+If your tape drive is in fixed block mode and you have told Bacula to use
+different fixed block sizes or variable block sizes (default), you will get
+errors when Bacula attempts to forward space to the correct block (the kernel
+driver's idea of tape blocks will not correspond to Bacula's).
+
+All modern tape drives support variable tape blocks, but some older drives (in
+particular the QIC drives) as well as the ATAPI ide-scsi driver run only in
+fixed block mode. The Travan tape drives also apparently must run in fixed
+block mode (to be confirmed).
+
+Even in variable block mode, with the exception of the first record on the
+second or subsequent volume of a multi-volume backup, Bacula will write blocks
+of a fixed size. However, in reading a tape, Bacula will assume that for each
+read request, exactly one block from the tape will be transferred. This the
+most common way that tape drives work and is well supported by {\bf Bacula}.
+
+Drives that run in fixed block mode can cause serious problems for Bacula if
+the drive's block size does not correspond exactly to {\bf Bacula's} block
+size. In fixed block size mode, drivers may transmit a partial block or
+multiple blocks for a single read request. From {\bf Bacula's} point of view,
+this destroys the concept of tape blocks. It is much better to run in variable
+block mode, and almost all modern drives (the OnStream is an exception) run in
+variable block mode. In order for Bacula to run in fixed block mode, you must
+include the following records in the Storage daemon's Device resource
+definition:
+
+\footnotesize
+\begin{verbatim}
+Minimum Block Size = nnn
+Maximum Block Size = nnn
+\end{verbatim}
+\normalsize
+
+where {\bf nnn} must be the same for both records and must be identical to the
+driver's fixed block size.
+
+We recommend that you avoid this configuration if at all possible by using
+variable block sizes.
+
+If you must run with fixed size blocks, make sure they are not 512 bytes. This
+is too small and the overhead that Bacula has with each record will become
+excessive. If at all possible set any fixed block size to something like
+64,512 bytes or possibly 32,768 if 64,512 is too large for your drive. See
+below for the details on checking and setting the default drive block size.
+
+To recover files from tapes written in fixed block mode, see below.
+
+\label{TapeModes}
+\subsection{Ensuring that the Tape Modes Are Properly Set -- {\bf Linux
+Only}}
+\index[general]{Ensuring that the Tape Modes Are Properly Set -- Linux Only}
+
+If you have a modern SCSI tape drive and you are having problems with the {\bf
+test} command as noted above, it may be that some program has set one or more
+of your SCSI driver's options to non-default values. For example, if your
+driver is set to work in SysV manner, Bacula will not work correctly because
+it expects BSD behavior. To reset your tape drive to the default values, you
+can try the following, but {\bf ONLY} if you have a SCSI tape drive on a {\bf
+Linux} system:
+
+\footnotesize
+\begin{verbatim}
+become super user
+mt -f /dev/nst0 rewind
+mt -f /dev/nst0 stoptions buffer-writes async-writes read-ahead
+\end{verbatim}
+\normalsize
+
+The above commands will clear all options and then set those specified. None
+of the specified options are required by Bacula, but a number of other options
+such as SysV behavior must not be set. Bacula does not support SysV tape
+behavior. On systems other than Linux, you will need to consult your {\bf mt}
+man pages or documentation to figure out how to do the same thing. This should
+not really be necessary though -- for example, on both Linux and Solaris
+systems, the default tape driver options are compatible with Bacula.
+On Solaris systems, you must take care to specify the correct device
+name on the {\bf Archive device} directive. See above for more details.
+
+You may also want to ensure that no prior program has set the default block
+size, as happened to one user, by explicitly turning it off with:
+
+\footnotesize
+\begin{verbatim}
+mt -f /dev/nst0 defblksize 0
+\end{verbatim}
+\normalsize
+
+If you are running a Linux
+system, and the above command does not work, it is most likely because you
+have not loaded the appropriate {\bf mt} package, which is often called
+{\bf mt\_st}, but may differ according to your distribution.
+
+If you would like to know what options you have set before making any of the
+changes noted above, you can now view them on Linux systems, thanks to a tip
+provided by Willem Riede. Do the following:
+
+\footnotesize
+\begin{verbatim}
+become super user
+mt -f /dev/nst0 stsetoptions 0
+grep st0 /var/log/messages
+\end{verbatim}
+\normalsize
+
+and you will get output that looks something like the following:
+
+\footnotesize
+\begin{verbatim}
+kernel: st0: Mode 0 options: buffer writes: 1, async writes: 1, read ahead: 1
+kernel: st0: can bsr: 0, two FMs: 0, fast mteom: 0, auto lock: 0,
+kernel: st0: defs for wr: 0, no block limits: 0, partitions: 0, s2 log: 0
+kernel: st0: sysv: 0 nowait: 0
+\end{verbatim}
+\normalsize
+
+Note, I have chopped off the beginning of the line with the date and machine
+name for presentation purposes.
+
+Some people find that the above settings only last until the next reboot, so
+please check this otherwise you may have unexpected problems.
+
+Beginning with Bacula version 1.35.8, if Bacula detects that you are running
+in variable block mode, it will attempt to set your drive appropriately. All
+OSes permit setting variable block mode, but some OSes do not permit setting
+the other modes that Bacula needs to function properly.
+
+\label{compression}
+\subsection{Tape Hardware Compression and Blocking Size}
+\index[general]{Tape Hardware Compression and Blocking Size}
+\index[general]{Size!Tape Hardware Compression and Blocking Size}
+
+You should be able to verify the tape compression status with sysfs on Linux.
+\begin{verbatim}
+cat /sys/class/scsi_tape/nst0/default_compression
+\end{verbatim}
+
+You can, turn it on by using (on Linux):
+
+\footnotesize
+\begin{verbatim}
+become super user
+mt -f /dev/nst0 defcompression 1
+\end{verbatim}
+\normalsize
+
+and of course, if you use a zero instead of the one at the end, you will turn
+it off.
+
+If you have built the {\bf mtx} program in the {\bf depkgs} package, you can
+use tapeinfo to get quite a bit of information about your tape drive even if
+it is not an autochanger. This program is called using the SCSI control
+device. On Linux for tape drive /dev/nst0, this is usually /dev/sg0, while on
+FreeBSD for /dev/nsa0, the control device is often /dev/pass2. For example on
+my DDS-4 drive (/dev/nst0), I get the following:
+
+\footnotesize
+\begin{verbatim}
+tapeinfo -f /dev/sg0
+Product Type: Tape Drive
+Vendor ID: 'HP '
+Product ID: 'C5713A '
+Revision: 'H107'
+Attached Changer: No
+MinBlock:1
+MaxBlock:16777215
+SCSI ID: 5
+SCSI LUN: 0
+Ready: yes
+BufferedMode: yes
+Medium Type: Not Loaded
+Density Code: 0x26
+BlockSize: 0
+\end{verbatim}
+\normalsize
+
+where the {\bf DataCompEnabled: yes} means that tape hardware compression is
+turned on. You can turn it on and off (yes|no) by using the {\bf mt}
+commands given above. Also, this output will tell you if the {\bf BlockSize}
+is non-zero and hence set for a particular block size. Bacula is not likely to
+work in such a situation because it will normally attempt to write blocks of
+64,512 bytes, except the last block of the job which will generally be
+shorter. The first thing to try is setting the default block size to zero
+using the {\bf mt -f /dev/nst0 defblksize 0} command as shown above.
+On FreeBSD, this would be something like: {\bf mt -f /dev/nsa0 blocksize 0}.
+
+On some operating systems with some tape drives, the amount of data that
+can be written to the tape and whether or not compression is enabled is
+determined by the density usually the {\bf mt -f /dev/nst0 setdensity xxx} command.
+Often {\bf mt -f /dev/nst0 status} will print out the current
+density code that is used with the drive. Most systems, but unfortunately
+not all, set the density to the maximum by default. On some systems, you
+can also get a list of all available density codes with:
+{\bf mt -f /dev/nst0 densities} or a similar {\bf mt} command.
+Note, for DLT and SDLT devices, no-compression versus compression is very
+often controlled by the density code. On FreeBSD systems, the compression
+mode is set using {\bf mt -f /dev/nsa0 comp xxx} where xxx is the
+mode you want. In general, see {\bf man mt} for the options available on
+your system.
+
+Note, some of the above {\bf mt} commands may not be persistent depending
+on your system configuration. That is they may be reset if a program
+other than Bacula uses the drive or, as is frequently the case, on reboot
+of your system.
+
+If your tape drive requires fixed block sizes (very unusual), you can use the
+following records:
+
+\footnotesize
+\begin{verbatim}
+Minimum Block Size = nnn
+Maximum Block Size = nnn
+\end{verbatim}
+\normalsize
+
+in your Storage daemon's Device resource to force Bacula to write fixed size
+blocks (where you sent nnn to be the same for both of the above records). This
+should be done only if your drive does not support variable block sizes, or
+you have some other strong reasons for using fixed block sizes. As mentioned
+above, a small fixed block size of 512 or 1024 bytes will be very inefficient.
+Try to set any fixed block size to something like 64,512 bytes or larger if
+your drive will support it.
+
+Also, note that the {\bf Medium Type} field of the output of {\bf tapeinfo}
+reports {\bf Not Loaded}, which is not correct. As a consequence, you should
+ignore that field as well as the {\bf Attached Changer} field.
+
+To recover files from tapes written in fixed block mode, see below.

+
+\subsection{Tape Modes on FreeBSD}
+\index[general]{FreeBSD!Tape Modes on}
+\index[general]{Tape Modes on FreeBSD}
+
+On most FreeBSD systems such as 4.9 and most tape drives, Bacula should run
+with:
+
+\footnotesize
+\begin{verbatim}
+mt -f /dev/nsa0 seteotmodel 2
+mt -f /dev/nsa0 blocksize 0
+mt -f /dev/nsa0 comp enable
+\end{verbatim}
+\normalsize
+
+You might want to put those commands in a startup script to make sure your
+tape driver is properly initialized before running Bacula, because
+depending on your system configuration, these modes may be reset if a
+program other than Bacula uses the drive or when your system is rebooted.
+
+Then according to what the {\bf btape test} command returns, you will probably
+need to set the following (see below for an alternative):
+
+\footnotesize
+\begin{verbatim}
+ Hardware End of Medium = no
+ BSF at EOM = yes
+ Backward Space Record = no
+ Backward Space File = no
+ Fast Forward Space File = no
+ TWO EOF = yes
+\end{verbatim}
+\normalsize
+
+Then be sure to run some append tests with Bacula where you start and stop
+Bacula between appending to the tape, or use {\bf btape} version 1.35.1 or
+greater, which includes simulation of stopping/restarting Bacula.
+
+Please see the file {\bf platforms/freebsd/pthreads-fix.txt} in the main
+Bacula directory concerning {\bf important} information concerning
+compatibility of Bacula and your system. A much more optimal Device
+configuration is shown below, but does not work with all tape drives. Please
+test carefully before putting either into production.
+
+Note, for FreeBSD 4.10-RELEASE, using a Sony TSL11000 L100 DDS4 with an
+autochanger set to variable block size and DCLZ compression, Brian McDonald
+reports that to get Bacula to append correctly between Bacula executions,
+the correct values to use are:
+
+\footnotesize
+\begin{verbatim}
+mt -f /dev/nsa0 seteotmodel 1
+mt -f /dev/nsa0 blocksize 0
+mt -f /dev/nsa0 comp enable
+\end{verbatim}
+\normalsize
+
+and
+
+\footnotesize
+\begin{verbatim}
+ Hardware End of Medium = no
+ BSF at EOM = no
+ Backward Space Record = no
+ Backward Space File = no
+ Fast Forward Space File = yes
+ TWO EOF = no
+\end{verbatim}
+\normalsize
+
+This has been confirmed by several other people using different hardware. This
+configuration is the preferred one because it uses one EOF and no backspacing
+at the end of the tape, which works much more efficiently and reliably with
+modern tape drives.
+
+Finally, here is a Device configuration that Danny Butroyd reports to work
+correctly with the Overland Powerloader tape library using LT0-2 and
+FreeBSD 5.4-Stable:
+
+\footnotesize
+\begin{verbatim}
+# Overland Powerloader LT02 - 17 slots single drive
+Device {
+ Name = Powerloader
+ Media Type = LT0-2
+ Archive Device = /dev/nsa0
+ AutomaticMount = yes;
+ AlwaysOpen = yes;
+ RemovableMedia = yes;
+ RandomAccess = no;
+ Changer Command = "/usr/local/sbin/mtx-changer %c %o %S %a %d"
+ Changer Device = /dev/pass2
+ AutoChanger = yes
+ Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
+
+ # FreeBSD Specific Settings
+ Offline On Unmount = no
+ Hardware End of Medium = no
+ BSF at EOM = yes
+ Backward Space Record = no
+ Fast Forward Space File = no
+ TWO EOF = yes
+}
+
+The following Device resource works fine with Dell PowerVault 110T and
+120T devices on both FreeBSD 5.3 and on NetBSD 3.0. It also works
+with Sony AIT-2 drives on FreeBSD.
+\footnotesize
+\begin{verbatim}
+Device {
+ ...
+ # FreeBSD/NetBSD Specific Settings
+ Hardware End of Medium = no
+ BSF at EOM = yes
+ Backward Space Record = no
+ Fast Forward Space File = yes
+ TWO EOF = yes
+}
+\end{verbatim}
+\normalsize
+
+On FreeBSD version 6.0, it is reported that you can even set
+Backward Space Record = yes.

+\subsection{Finding your Tape Drives and Autochangers on FreeBSD}
+\index[general]{FreeBSD!Finding Tape Drives and Autochangers}
+\index[general]{Finding Tape Drives and Autochangers on FreeBSD}
+
+On FreeBSD, you can do a {\bf camcontrol devlist} as root to determine what
+drives and autochangers you have. For example,
+
+\footnotesize
+\begin{verbatim}
+undef# camcontrol devlist
+ at scbus0 target 2 lun 0 (pass0,sa0)
+ at scbus0 target 4 lun 0 (pass1,sa1)
+ at scbus0 target 4 lun 1 (pass2)
+\end{verbatim}
+\normalsize
+
+from the above, you can determine that there is a tape drive on {\bf /dev/sa0}
+and another on {\bf /dev/sa1} in addition since there is a second line for the
+drive on {\bf /dev/sa1}, you know can assume that it is the control device for
+the autochanger (i.e. {\bf /dev/pass2}). It is also the control device name to
+use when invoking the tapeinfo program. E.g.
+

+\subsection{Using btape to Simulate Filling a Tape}
+\index[general]{Using btape to Simulate Filling a Tape}
+\index[general]{Tape!Using btape to Simulate Filling}
+
+Because there are often problems with certain tape drives or systems when end
+of tape conditions occur, {\bf btape} has a special command {\bf fill} that
+causes it to write random data to a tape until the tape fills. It then writes
+at least one more Bacula block to a second tape. Finally, it reads back both
+tapes to ensure that the data has been written in a way that Bacula can
+recover it. Note, there is also a single tape option as noted below, which you
+should use rather than the two tape test. See below for more details.
+
+This can be an extremely time consuming process (here it is about 6 hours) to
+fill a full tape. Note, that btape writes random data to the tape when it is
+filling it. This has two consequences: 1. it takes a bit longer to generate
+the data, especially on slow CPUs. 2. the total amount of data is
+approximately the real physical capacity of your tape, regardless of whether
+or not the tape drive compression is on or off. This is because random data
+does not compress very much.
+
+To begin this test, you enter the {\bf fill} command and follow the
+instructions. There are two options: the simple single tape option and the
+multiple tape option. Please use only the simple single tape option because
+the multiple tape option still doesn't work totally correctly. If the single
+tape option does not succeed, you should correct the problem before using
+Bacula.

+\section{Recovering Files Written With Fixed Block Sizes}
+\index[general]{Recovering Files Written With Fixed Block Sizes}
+
+If you have been previously running your tape drive in fixed block mode
+(default 512) and Bacula with variable blocks (default), then in version
+1.32f-x and 1.34 and above, Bacula will fail to recover files because it does
+block spacing, and because the block sizes don't agree between your tape drive
+and Bacula it will not work.
+
+The long term solution is to run your drive in variable block mode as
+described above. However, if you have written tapes using fixed block sizes,
+this can be a bit of a pain. The solution to the problem is: while you are
+doing a restore command using a tape written in fixed block size, ensure that
+your drive is set to the fixed block size used while the tape was written.
+Then when doing the {\bf restore} command in the Console program, do not
+answer the prompt {\bf yes/mod/no}. Instead, edit the bootstrap file (the
+location is listed in the prompt) using any ASCII editor. Remove all {\bf
+VolBlock} lines in the file. When the file is re-written, answer the question,
+and Bacula will run without using block positioning, and it should recover
+your files.
+
+\label{BlockModes}
+\section{Tape Blocking Modes}
+\index[general]{Modes!Tape Blocking}
+\index[general]{Tape Blocking Modes}
+
+SCSI tapes may either be written in {\bf variable} or {\bf fixed} block sizes.
+Newer drives support both modes, but some drives such as the QIC devices
+always use fixed block sizes. Bacula attempts to fill and write complete
+blocks (default 65K), so that in normal mode (variable block size), Bacula
+will always write blocks of the same size except the last block of a Job. If
+Bacula is configured to write fixed block sizes, it will pad the last block of
+the Job to the correct size. Bacula expects variable tape block size drives to
+behave as follows: Each write to the drive results in a single record being
+written to the tape. Each read returns a single record. If you request less
+bytes than are in the record, only those number of bytes will be returned, but
+the entire logical record will have been read (the next read will retrieve the
+next record). Thus data from a single write is always returned in a single
+read, and sequentially written records are returned by sequential reads.
+
+Bacula expects fixed block size tape drives to behave as follows: If a write
+length is greater than the physical block size of the drive, the write will be
+written as two blocks each of the fixed physical size. This single write may
+become multiple physical records on the tape. (This is not a good situation).
+According to the documentation, one may never write an amount of data that is
+not the exact multiple of the blocksize (it is not specified if an error
+occurs or if the the last record is padded). When reading, it is my
+understanding that each read request reads one physical record from the tape.
+Due to the complications of fixed block size tape drives, you should avoid
+them if possible with Bacula, or you must be ABSOLUTELY certain that you use
+fixed block sizes within Bacula that correspond to the physical block size of
+the tape drive. This will ensure that Bacula has a one to one correspondence
+between what it writes and the physical record on the tape.
+
+Please note that Bacula will not function correctly if it writes a block and
+that block is split into two or more physical records on the tape. Bacula
+assumes that each write causes a single record to be written, and that it can
+sequentially recover each of the blocks it has written by using the same
+number of sequential reads as it had written.
+
+\section{Details of Tape Modes}
+\index[general]{Modes!Details}
+\index[general]{Details of Tape Modes}
+Rudolf Cejka has provided the following information concerning
+certain tape modes and MTEOM.
+
+\begin{description}
+\item[Tape level]
+ It is always possible to position filemarks or blocks, whereas
+ positioning to the end-of-data is only optional feature, however it is
+ implemented very often. SCSI specification also talks about optional
+ sequential filemarks, setmarks and sequential setmarks, but these are not
+ implemented so often. Modern tape drives keep track of file positions in
+ built-in chip (AIT, LTO) or at the beginning of the tape (SDLT), so there
+ is not any speed difference, if end-of-data or filemarks is used (I have
+ heard, that LTO-1 from all 3 manufacturers do not use its chip for file
+ locations, but a tape as in SDLT case, and I'm not sure about LTO-2 and
+ LTO-3 case). However there is a big difference, that end-of-data ignores
+ file position, whereas filemarks returns the real number of skipped
+ files, so OS can track current file number just in filemarks case.
+
+\item[OS level]
+ Solaris does use just SCSI SPACE Filemarks, it does not support SCSI
+ SPACE End-of-data. When MTEOM is called, Solaris does use SCSI SPACE
+ Filemarks with count = 1048576 for fast mode, and combination of SCSI
+ SPACE Filemarks with count = 1 with SCSI SPACE Blocks with count = 1 for
+ slow mode, so EOD mark on the tape on some older tape drives is not
+ skipped. File number is always tracked for MTEOM.
+
+ Linux does support both SCSI SPACE Filemarks and End-of-data: When MTEOM
+ is called in MT\_ST\_FAST\_MTEOM mode, SCSI SPACE End-of-data is used.
+ In the other case, SCSI SPACE Filemarks with count =
+ 8388607 is used.
+ There is no real slow mode like in Solaris - I just expect, that for
+ older tape drives Filemarks may be slower than End-of-data, but not so
+ much as in Solaris slow mode. File number is tracked for MTEOM just
+ without MT\_ST\_FAST\_MTEOM - when MT\_ST\_FAST\_MTEOM is used, it is not.
+
+ FreeBSD does support both SCSI SPACE Filemarks and End-of-data, but when
+ MTEOD (MTEOM) is called, SCSI SPACE End-of-data is always used. FreeBSD
+ never use SCSI SPACE Filemarks for MTEOD. File number is never tracked
+ for MTEOD.
+
+\item[Bacula level]
+ When {\bf Hardware End of Medium = Yes} is used, MTEOM is called, but it
+ does not mean, that hardware End-of-data must be used. When Hardware End
+ of Medium = No, if Fast Forward Space File = Yes, MTFSF with count =
+ 32767 is used, else Block Read with count = 1 with Forward Space File
+ with count = 1 is used, which is really very slow.
+
+\item [Hardware End of Medium = Yes|No]
+ The name of this option is misleading and is the source of confusion,
+ because it is not the hardware EOM, what is really switched here.
+
+ If I use Yes, OS must not use SCSI SPACE End-of-data, because Bacula
+ expects, that there is tracked file number, which is not supported by
+ SCSI specification. Instead, the OS have to use SCSI SPACE Filemarks.
+
+ If I use No, an action depends on Fast Forward Space File.
+
+ When I set {\bf Hardware End of Medium = no}
+ and {\bf Fast Forward Space File = no}
+ file positioning was very slow
+ on my LTO-3 (about ten to 100 minutes), but
+
+ with {\bf Hardware End of Medium = no} and
+{\bf Fast Forward Space File = yes}, the time is ten to
+100 times faster (about one to two minutes).
+

+\section{Tape Performance Problems}
+\index[general]{Tape Performance}
+If you have LTO-3 or LTO-4 drives, you should be able to
+fairly good transfer rates, from 60 to 90 MB/second, providing
+you have fast disks, GigaBit Ethernet connections, and possibly set
+up your tape buffer size a bit from the default 64K.
+
+If you are not getting good performance, consider some of the following
+suggestions from the Allen Balck on the Bacula Users email list:
+
+\begin{enumerate}
+\item You are using an old HBA (i.e. SCSI-1, which only does 5 MB/s)
+
+\item There are other, slower, devices on the SCSI bus. The HBA will
+ negotiate the speed of every device down to the speed of the
+ slowest.
+
+\item There is a termination problem on the bus (either too much or
+ too little termination). The HBA will drop the bus speed in an
+ attempt to increase the reliability of the bus.
+
+\item Loose or damaged cabling - this will probably make the HBA "think"
+ you have a termination problem and it will react as in 3 above.
+\end{enumerate}
+
+See if /var/adm/messages (or /var/log/messages) tells you what the sync
+rate of the SCSI devices/bus are. Also, the next time you reboot, the
+BIOS may be able to tell you what the rate of each device is.

+3992 Bad autochanger "load slot 1, drive 1": ERR=Child exited with code 1.

+
+and you are running your Storage daemon as non-root, then most likely
+you are having permissions problems with the control channel. Running
+as root, set permissions on /dev/sgX so that the userid and group of
+your Storage daemon can access the device. You need to ensure that you
+all access to the proper control device, and if you don't have any
+SCSI disk drives (including SATA drives), you might want to change
+the permissions on /dev/sg*.

+you are sure that your OS parameters are properly configured as

+\section{Upgrading Bacula Versions}
+\label{upgrading}
+\index[general]{Upgrading Bacula Versions }
+\index[general]{Versions!Upgrading Bacula }
+\index[general]{Upgrading}
+
+The first thing to do before upgrading from one version to another is to
+ensure that you don't overwrite or delete your production (current) version
+of Bacula until you have tested that the new version works.
+
+If you have installed Bacula into a single directory, this is simple: simply
+make a copy of your Bacula directory.
+
+If you have done a more typical Unix installation where the binaries are
+placed in one directory and the configuration files are placed in another,
+then the simplest way is to configure your new Bacula to go into a single
+file. Alternatively, make copies of all your binaries and especially your
+conf files.
+
+Whatever your situation may be (one of the two just described), you should
+probably start with the {\bf defaultconf} script that can be found in the {\bf
+examples} subdirectory. Copy this script to the main Bacula directory, modify
+it as necessary (there should not need to be many modifications), configure
+Bacula, build it, install it, then stop your production Bacula, copy all the
+{\bf *.conf} files from your production Bacula directory to the test Bacula
+directory, start the test version, and run a few test backups. If all seems
+good, then you can proceed to install the new Bacula in place of or possibly
+over the old Bacula.
+
+When installing a new Bacula you need not worry about losing the changes you
+made to your configuration files as the installation process will not
+overwrite them providing that you do not do a {\bf make uninstall}.
+
+If the new version of Bacula requires an upgrade to the database,
+you can upgrade it with the script {\bf update\_bacula\_tables}, which
+will be installed in your scripts directory (default {\bf /etc/bacula}),
+or alternatively, you can find it in the
+{\bf \lt{}bacula-source\gt{}/src/cats} directory.
+
+\section{Getting Notified of Job Completion}
+\label{notification}
+\index[general]{Getting Notified of Job Completion }
+\index[general]{Completion!Getting Notified of Job }
+
+One of the first things you should do is to ensure that you are being properly
+notified of the status of each Job run by Bacula, or at a minimum of each Job
+that terminates with an error.
+
+Until you are completely comfortable with {\bf Bacula}, we recommend that you
+send an email to yourself for each Job that is run. This is most easily
+accomplished by adding an email notification address in the {\bf Messages}
+resource of your Director's configuration file. An email is automatically
+configured in the default configuration files, but you must ensure that the
+default {\bf root} address is replaced by your email address.
+
+For additional examples of how to configure a Bacula, please take a look at the
+{\bf .conf} files found in the {\bf examples} sub-directory. We recommend the
+following configuration (where you change the paths and email address to
+correspond to your setup). Note, the {\bf mailcommand} and {\bf
+operatorcommand} should be on a single line. They were split here for
+presentation:
+
+\footnotesize
+\begin{verbatim}
+Messages {
+ Name = Standard
+ mailcommand = "/home/bacula/bin/bsmtp -h localhost
+ -f \"\(Bacula\) %r\"
+ -s \"Bacula: %t %e of %c %l\" %r"
+ operatorcommand = "/home/bacula/bin/bsmtp -h localhost
+ -f \"\(Bacula\) %r\"
+ -s \"Bacula: Intervention needed for %j\" %r"
+ Mail = your-email-address = all, !skipped, !terminate
+ append = "/home/bacula/bin/log" = all, !skipped, !terminate
+ operator = your-email-address = mount
+ console = all, !skipped, !saved
+}
+\end{verbatim}
+\normalsize
+
+You will need to ensure that the {\bf /home/bacula/bin} path on the {\bf
+mailcommand} and the {\bf operatorcommand} lines point to your {\bf Bacula}
+binary directory where the {\bf bsmtp} program will be installed. You will
+also want to ensure that the {\bf your-email-address} is replaced by your
+email address, and finally, you will also need to ensure that the {\bf
+/home/bacula/bin/log} points to the file where you want to log all messages.
+
+With the above Messages resource, you will be notified by email of every Job
+that ran, all the output will be appended to the {\bf log} file you specify,
+all output will be directed to the console program, and all mount messages
+will be emailed to you. Note, some messages will be sent to multiple
+destinations.
+
+The form of the mailcommand is a bit complicated, but it allows you to
+distinguish whether the Job terminated in error or terminated normally. Please
+see the
+\ilink{Mail Command}{mailcommand} section of the Messages
+Resource chapter of this manual for the details of the substitution characters
+used above.
+
+Once you are totally comfortable with Bacula as I am, or if you have a large
+number of nightly Jobs as I do (eight), you will probably want to change the
+{\bf Mail} command to {\bf Mail On Error} which will generate an email message
+only if the Job terminates in error. If the Job terminates normally, no email
+message will be sent, but the output will still be appended to the log file as
+well as sent to the Console program.
+
+\section{Getting Email Notification to Work}
+\label{email}
+\index[general]{Work!Getting Email Notification to }
+\index[general]{Getting Email Notification to Work }
+
+The section above describes how to get email notification of job status.
+Occasionally, however, users have problems receiving any email at all. In that
+case, the things to check are the following:
+
+\begin{itemize}
+\item Ensure that you have a valid email address specified on your {\bf Mail}
+ record in the Director's Messages resource. The email address should be fully
+ qualified. Simply using {\bf root} generally will not work, rather you should
+use {\bf root@localhost} or better yet your full domain.
+\item Ensure that you do not have a {\bf Mail} record in the Storage daemon's
+ or File daemon's configuration files. The only record you should have is {\bf
+ director}:
+
+\footnotesize
+\begin{verbatim}
+ director = director-name = all
+
+\end{verbatim}
+\normalsize
+
+\item If all else fails, try replacing the {\bf mailcommand} with
+
+ \footnotesize
+\begin{verbatim}
+mailcommand = "mail -s test your@domain.com"
+\end{verbatim}
+\normalsize
+
+\item Once the above is working, assuming you want to use {\bf bsmtp}, submit
+ the desired bsmtp command by hand and ensure that the email is delivered,
+ then put that command into {\bf Bacula}. Small differences in things such as
+the parenthesis around the word Bacula can make a big difference to some
+bsmtp programs. For example, you might start simply by using:
+
+\footnotesize
+\begin{verbatim}
+mailcommand = "/home/bacula/bin/bsmtp -f \"root@localhost\" %r"
+\end{verbatim}
+\normalsize
+
+\end{itemize}
+
+\section{Getting Notified that Bacula is Running}
+\label{JobNotification}
+\index[general]{Running!Getting Notified that Bacula is }
+\index[general]{Getting Notified that Bacula is Running }
+
+If like me, you have setup Bacula so that email is sent only when a Job has
+errors, as described in the previous section of this chapter, inevitably, one
+day, something will go wrong and {\bf Bacula} can stall. This could be because
+Bacula crashes, which is vary rare, or more likely the network has caused {\bf
+Bacula} to {\bf hang} for some unknown reason.
+
+To avoid this, you can use the {\bf RunAfterJob} command in the Job resource
+to schedule a Job nightly, or weekly that simply emails you a message saying
+that Bacula is still running. For example, I have setup the following Job in
+my Director's configuration file:
+
+\footnotesize
+\begin{verbatim}
+Schedule {
+ Name = "Watchdog"
+ Run = Level=Full sun-sat at 6:05
+}
+Job {
+ Name = "Watchdog"
+ Type = Admin
+ Client=Watchdog
+ FileSet="Verify Set"
+ Messages = Standard
+ Storage = DLTDrive
+ Pool = Default
+ Schedule = "Watchdog"
+ RunAfterJob = "/home/kern/bacula/bin/watchdog %c %d"
+}
+Client {
+ Name = Watchdog
+ Address = rufus
+ FDPort = 9102
+ Catalog = Verify
+ Password = ""
+ File Retention = 1day
+ Job Retention = 1 month
+ AutoPrune = yes
+}
+\end{verbatim}
+\normalsize
+
+Where I established a schedule to run the Job nightly. The Job itself is type
+{\bf Admin} which means that it doesn't actually do anything, and I've defined
+a FileSet, Pool, Storage, and Client, all of which are not really used (and
+probably don't need to be specified). The key aspect of this Job is the
+command:
+
+\footnotesize
+\begin{verbatim}
+ RunAfterJob = "/home/kern/bacula/bin/watchdog %c %d"
+\end{verbatim}
+\normalsize
+
+which runs my "watchdog" script. As an example, I have added the Job codes
+\%c and \%d which will cause the Client name and the Director's name to be
+passed to the script. For example, if the Client's name is {\bf Watchdog} and
+the Director's name is {\bf main-dir} then referencing \$1 in the script would
+get {\bf Watchdog} and referencing \$2 would get {\bf main-dir}. In this case,
+having the script know the Client and Director's name is not really useful,
+but in other situations it may be.
+
+You can put anything in the watchdog script. In my case, I like to monitor the
+size of my catalog to be sure that {\bf Bacula} is really pruning it. The
+following is my watchdog script:
+
+\footnotesize
+\begin{verbatim}
+#!/bin/sh
+cd /home/kern/mysql/var/bacula
+du . * |
+/home/kern/bacula/bin/bsmtp \
+ -f "\(Bacula\) abuse@whitehouse.com" -h mail.yyyy.com \
+ -s "Bacula running" abuse@whitehouse.com
+\end{verbatim}
+\normalsize
+
+If you just wish to send yourself a message, you can do it with:
+
+\footnotesize
+\begin{verbatim}
+#!/bin/sh
+cd /home/kern/mysql/var/bacula
+/home/kern/bacula/bin/bsmtp \
+ -f "\(Bacula\) abuse@whitehouse.com" -h mail.yyyy.com \
+ -s "Bacula running" abuse@whitehouse.com <<END-OF-DATA
+Bacula is still running!!!
+END-OF-DATA
+\end{verbatim}
+\normalsize
+
+\section{Maintaining a Valid Bootstrap File}
+\label{bootstrap}
+\index[general]{Maintaining a Valid Bootstrap File }
+\index[general]{File!Maintaining a Valid Bootstrap }
+
+By using a
+\ilink{ WriteBootstrap}{writebootstrap} record in each of your
+Director's Job resources, you can constantly maintain a
+\ilink{bootstrap}{BootstrapChapter} file that will enable you to
+recover the state of your system as of the last backup without having the
+Bacula catalog. This permits you to more easily recover from a disaster that
+destroys your Bacula catalog.
+
+When a Job resource has a {\bf WriteBootstrap} record, Bacula will maintain
+the designated file (normally on another system but mounted by NFS) with up to
+date information necessary to restore your system. For example, in my
+Director's configuration file, I have the following record:
+
+\footnotesize
+\begin{verbatim}
+ Write Bootstrap = "/mnt/deuter/files/backup/client-name.bsr"
+\end{verbatim}
+\normalsize
+
+where I replace {\bf client-name} by the actual name of the client that is
+being backed up. Thus, Bacula automatically maintains one file for each of my
+clients. The necessary bootstrap information is appended to this file during
+each {\bf Incremental} backup, and the file is totally rewritten during each
+{\bf Full} backup.
+
+Note, one disadvantage of writing to an NFS mounted volume as I do is
+that if the other machine goes down, the OS will wait forever on the fopen()
+call that Bacula makes. As a consequence, Bacula will completely stall until
+the machine exporting the NFS mounts comes back up. A possible solution to this
+problem was provided by Andrew Hilborne, and consists of using the {\bf soft}
+option instead of the {\bf hard} option when mounting the NFS volume, which is
+typically done in {\bf /etc/fstab}/. The NFS documentation explains these
+options in detail. However, I found that with the {\bf soft} option
+NFS disconnected frequently causing even more problems.
+
+If you are starting off in the middle of a cycle (i.e. with Incremental
+backups) rather than at the beginning (with a Full backup), the {\bf
+bootstrap} file will not be immediately valid as it must always have the
+information from a Full backup as the first record. If you wish to synchronize
+your bootstrap file immediately, you can do so by running a {\bf restore}
+command for the client and selecting a full restore, but when the restore
+command asks for confirmation to run the restore Job, you simply reply no,
+then copy the bootstrap file that was written to the location specified on the
+{\bf Write Bootstrap} record. The restore bootstrap file can be found in {\bf
+restore.bsr} in the working directory that you defined. In the example given
+below for the client {\bf rufus}, my input is shown in bold. Note, the JobId
+output has been partially truncated to fit on the page here:
+
+\footnotesize

+\section{Rejected Volumes After a Crash}
+\label{RejectedVolumes}
+\index[general]{Crash!Rejected Volumes After a }
+\index[general]{Rejected Volumes After a Crash }
+
+Bacula keeps a count of the number of files on each Volume in its Catalog
+database so that before appending to a tape, it can verify that the number of
+files are correct, and thus prevent overwriting valid data. If the Director or
+the Storage daemon crashes before the job has completed, the tape will contain
+one more file than is noted in the Catalog, and the next time you attempt to
+use the same Volume, Bacula will reject it due to a mismatch between the
+physical tape (Volume) and the catalog.
+
+The easiest solution to this problem is to label a new tape and start fresh.
+If you wish to continue appending to the current tape, you can do so by using
+the {\bf update} command in the console program to change the {\bf Volume
+Files} entry in the catalog. A typical sequence of events would go like the
+following:
+
+\footnotesize
+\begin{verbatim}
+- Bacula crashes
+- You restart Bacula
+\end{verbatim}
+\normalsize
+
+Bacula then prints:
+
+\footnotesize
+\begin{verbatim}

+(note, lines wrapped for presentation)
+The key here is the line that reads:
+
+\footnotesize
+\begin{verbatim}
+ The number of files mismatch! Volume=11 Catalog=10
+\end{verbatim}
+\normalsize
+
+It says that Bacula found eleven files on the volume, but that the catalog
+says there should be ten. When you see this, you can be reasonably sure that
+the SD was interrupted while writing before it had a chance to update the
+catalog. As a consequence, you can just modify the catalog count to eleven,
+and even if the catalog contains references to files saved in file 11,
+everything will be OK and nothing will be lost. Note that if the SD had
+written several file marks to the volume, the difference between the Volume
+count and the Catalog count could be larger than one, but this is unusual.
+
+If on the other hand the catalog is marked as having more files than Bacula
+found on the tape, you need to consider the possible negative consequences of
+modifying the catalog. Please see below for a more complete discussion of
+this.
+
+Continuing with the example of {\bf Volume = 11 Catalog = 10}, to enable to
+Bacula to append to the tape, you do the following:
+
+\footnotesize
+\begin{verbatim}
+update
+Update choice:
+ 1: Volume parameters

+\end{verbatim}
+\normalsize
+
+Here, you have selected {\bf 9} in order to update the Volume Files, then you
+changed it from {\bf 10} to {\bf 11}, and you now answer {\bf 1} to change the
+Volume Status.
+
+\footnotesize
+\begin{verbatim}

+\end{verbatim}
+\normalsize
+
+At this point, you have changed the Volume Files from {\bf 10} to {\bf 11} to
+account for the last file that was written but not updated in the database,
+and you changed the Volume Status back to {\bf Append}.
+
+This was a lot of words to describe something quite simple.
+
+The {\bf Volume Files} option exists only in version 1.29 and later, and you
+should be careful using it. Generally, if you set the value to that which
+Bacula said is on the tape, you will be OK, especially if the value is one
+more than what is in the catalog.
+
+Now lets consider the case:
+
+\footnotesize
+\begin{verbatim}
+ The number of files mismatch! Volume=10 Catalog=12
+\end{verbatim}
+\normalsize
+
+Here the Bacula found fewer files on the volume than what is marked in the
+catalog. Now, in this case, you should hesitate a lot before modifying the count
+in the catalog, because if you force the catalog from 12 to 10, Bacula will
+start writing after the file 10 on the tape, possibly overwriting valid data,
+and if you ever try to restore any of the files that the catalog has marked as
+saved on Files 11 and 12, all chaos will break out. In this case, you will
+probably be better off using a new tape. In fact, you might want to see what
+files the catalog claims are actually stored on that Volume, and back them up
+to another tape and recycle this tape.

+\section{Security Considerations}
+\label{security}
+\index[general]{Considerations!Security }
+\index[general]{Security Considerations }
+
+Only the File daemon needs to run with root permission (so that it can access
+all files). As a consequence, you may run your Director, Storage daemon, and
+MySQL or PostgreSQL database server as non-root processes. Version 1.30 has
+the {\bf -u} and the {\bf -g} options that allow you to specify a userid and
+groupid on the command line to be used after Bacula starts.
+
+As of version 1.33, thanks to Dan Langille, it is easier to configure the
+Bacula Director and Storage daemon to run as non-root.
+
+You should protect the Bacula port addresses (normally 9101, 9102, and 9103)
+from outside access by a firewall or other means of protection to prevent
+unauthorized use of your daemons.
+
+You should ensure that the configuration files are not world readable since
+they contain passwords that allow access to the daemons. Anyone who can access
+the Director using a console program can restore any file from a backup
+Volume.
+
+You should protect your Catalog database. If you are using SQLite, make sure
+that the working directory is readable only by root (or your Bacula userid),
+and ensure that {\bf bacula.db} has permissions {\bf -rw-r\verb:--:r\verb:--:} (i.e. 640) or
+more strict. If you are using MySQL or PostgreSQL, please note that the Bacula
+setup procedure leaves the database open to anyone. At a minimum, you should
+assign the user {\bf bacula} a userid and add it to your Director's
+configuration file in the appropriate Catalog resource.
+
+If you use the make\_catalog\_backup script provided by Bacula, remember that
+you should take care when supplying passwords on the command line. Read the
+\ilink{Backing Up Your Bacula
+Database - Security Considerations }{BackingUpBaculaSecurityConsiderations}
+section for more information.

+\label{holiday}
+\index[general]{Schedules!Creating Holiday }
+\index[general]{Creating Holiday Schedules }
+
+If you normally change tapes every day or at least every Friday, but Thursday
+is a holiday, you can use a trick proposed by Lutz Kittler to ensure that no
+job runs on Thursday so that you can insert Friday's tape and be sure it will
+be used on Friday. To do so, define a {\bf RunJobBefore} script that normally
+returns zero, so that the Bacula job will normally continue. You can then
+modify the script to return non-zero on any day when you do not want Bacula to
+run the job.
+
+\section{Automatic Labeling Using Your Autochanger}
+\label{autolabel}
+\index[general]{Automatic Labeling Using Your Autochanger }
+\index[general]{Autochanger!Automatic Labeling Using Your }
+
+If you have an autochanger but it does not support barcodes, using a "trick"
+you can make Bacula automatically label all the volumes in your autochanger's
+magazine.
+
+First create a file containing one line for each slot in your autochanger that
+has a tape to be labeled. The line will contain the slot number a colon (:)
+then the Volume name you want to use. For example, create a file named {\bf
+volume-list}, which contains:
+
+\footnotesize
+\begin{verbatim}
+1:Volume001
+2:TestVolume02
+5:LastVolume
+\end{verbatim}
+\normalsize
+
+The records do not need to be in any order and you don't need to mention all
+the slots. Normally, you will have a consistent set of Volume names and a
+sequential set of numbers for each slot you want labeled. In the example
+above, I've left out slots 3 and 4 just as an example. Now, modify your {\bf
+mtx-changer} script and comment out all the lines in the {\bf list)} case by
+putting a \# in column 1. Then add the following two lines:
+
+\footnotesize
+\begin{verbatim}
+ cat <absolute-path>/volume-list
+ exit 0
+\end{verbatim}
+\normalsize
+
+so that the whole case looks like:
+
+\footnotesize
+\begin{verbatim}
+ list)
+#
+# commented out lines
+ cat <absolute-path>/volume-list
+ exit 0
+ ;;
+\end{verbatim}
+\normalsize
+
+where you replace \lt{}absolute-path\gt{} with the full path to the
+volume-list file. Then using the console, you enter the following command:
+
+\footnotesize
+\begin{verbatim}
+ label barcodes
+\end{verbatim}
+\normalsize
+
+and Bacula will proceed to mount the autochanger Volumes in the list and label
+them with the Volume names you have supplied. Bacula will think that the list
+was provided by the autochanger barcodes, but in reality, it was you who
+supplied the \lt{}barcodes\gt{}.
+
+If it seems to work, when it finishes, enter:
+
+\footnotesize
+\begin{verbatim}
+ list volumes
+\end{verbatim}
+\normalsize
+
+and you should see all the volumes nicely created.

+You may want to backup laptops or portables that are not always connected to
+the network. If you are using DHCP to assign an IP address to those machines
+when they connect, you will need to use the Dynamic Update capability of DNS
+to assign a name to those machines that can be used in the Address field of
+the Client resource in the Director's conf file.

+\label{Vacation}
+\index[general]{Vacation!Going on }
+\index[general]{Going on Vacation }
+
+At some point, you may want to be absent for a week or two and you want to
+make sure Bacula has enough tape left so that the backups will complete. You
+start by doing a {\bf list volumes} in the Console program:
+
+\footnotesize
+\begin{verbatim}
+list volumes
+
+Using default Catalog name=BackupDB DB=bacula
+Pool: Default
++---------+---------------+-----------+-----------+----------------+-

++---------+---------------+-----------+-----------+----------------+
+\end{verbatim}
+\normalsize
+
+Note, I have truncated the output for presentation purposes. What is
+significant, is that I can see that my current tape has almost 10 Gbytes of
+data, and that the average amount of data I get on my tapes is about 60
+Gbytes. So if I go on vacation now, I don't need to worry about tape capacity
+(at least not for short absences).
+
+Equally significant is the fact that I did go on vacation the 28th of June
+2003, and when I did the {\bf list volumes} command, my current tape at that
+time, DLT-07Jun03 MediaId 31, had 56.5 Gbytes written. I could see that the
+tape would fill shortly. Consequently, I manually marked it as {\bf Used} and
+replaced it with a fresh tape that I labeled as DLT-28Jun03, thus assuring
+myself that the backups would all complete without my intervention.

+\label{Case}
+\index[general]{Exclude Files on Windows Regardless of Case}
+% TODO: should this be put in the win32 chapter?
+% TODO: should all these tips be placed in other chapters?
+
+This tip was submitted by Marc Brueckner who wasn't sure of the case of some
+of his files on Win32, which is case insensitive. The problem is that Bacula
+thinks that {\bf /UNIMPORTANT FILES} is different from {\bf /Unimportant
+Files}. Marc was aware that the file exclusion permits wild-cards. So, he
+specified:
+
+\footnotesize
+\begin{verbatim}
+"/[Uu][Nn][Ii][Mm][Pp][Oo][Rr][Tt][Aa][Nn][Tt] [Ff][Ii][Ll][Ee][Ss]"
+\end{verbatim}
+\normalsize
+
+As a consequence, the above exclude works for files of any case.
+
+Please note that this works only in Bacula Exclude statement and not in
+Include.
+
+\section{Executing Scripts on a Remote Machine}
+\label{RemoteExecution}
+\index[general]{Machine!Executing Scripts on a Remote }
+\index[general]{Executing Scripts on a Remote Machine }
+
+This tip also comes from Marc Brueckner. (Note, this tip is probably outdated
+by the addition of {\bf ClientRunBeforJob} and {\bf ClientRunAfterJob} Job
+records, but the technique still could be useful.) First I thought the "Run
+Before Job" statement in the Job-resource is for executing a script on the
+remote machine (the machine to be backed up). (Note, this is possible as mentioned
+above by using {\bf ClientRunBeforJob} and {\bf ClientRunAfterJob}).
+It could be useful to execute
+scripts on the remote machine e.g. for stopping databases or other services
+while doing the backup. (Of course I have to start the services again when the
+backup has finished) I found the following solution: Bacula could execute
+scripts on the remote machine by using ssh. The authentication is done
+automatically using a private key. First you have to generate a keypair. I've
+done this by:
+
+\footnotesize
+\begin{verbatim}
+ssh-keygen -b 4096 -t dsa -f Bacula_key
+\end{verbatim}
+\normalsize
+
+This statement may take a little time to run. It creates a public/private key
+pair with no passphrase. You could save the keys in /etc/bacula. Now you have
+two new files : Bacula\_key which contains the private key and Bacula\_key.pub
+which contains the public key.
+
+Now you have to append the Bacula\_key.pub file to the file authorized\_keys
+in the \textbackslash{}root\textbackslash{}.ssh directory of the remote
+machine. Then you have to add (or uncomment) the line
+
+\footnotesize
+\begin{verbatim}
+AuthorizedKeysFile %h/.ssh/authorized_keys
+\end{verbatim}
+\normalsize
+
+to the sshd\_config file on the remote machine. Where the \%h stands for the
+home-directory of the user (root in this case).
+
+Assuming that your sshd is already running on the remote machine, you can now
+enter the following on the machine where Bacula runs:
+
+\footnotesize
+\begin{verbatim}
+ssh -i Bacula_key -l root <machine-name-or-ip-address> "ls -la"
+\end{verbatim}
+\normalsize
+
+This should execute the "ls -la" command on the remote machine.
+
+Now you could add lines like the following to your Director's conf file:
+
+\footnotesize
+\begin{verbatim}
+...
+Run Before Job = ssh -i /etc/bacula/Bacula_key 192.168.1.1 \
+ "/etc/init.d/database stop"
+Run After Job = ssh -i /etc/bacula/Bacula_key 192.168.1.1 \
+ "/etc/init.d/database start"
+...
+\end{verbatim}
+\normalsize
+
+Even though Bacula version 1.32 and later has a ClientRunBeforeJob, the ssh method still
+could be useful for updating all the Bacula clients on several remote machines
+in a single script.
+
+\section{Recycling All Your Volumes}
+\label{recycle}
+\index[general]{Recycling All Your Volumes }
+\index[general]{Volumes!Recycling All Your }
+
+This tip comes from Phil Stracchino.
+
+If you decide to blow away your catalog and start over, the simplest way to
+re-add all your prelabeled tapes with a minimum of fuss (provided you don't
+care about the data on the tapes) is to add the tape labels using the console
+{\bf add} command, then go into the catalog and manually set the VolStatus of
+every tape to {\bf Recycle}.
+
+The SQL command to do this is very simple, either use your vendor's
+command line interface (mysql, postgres, sqlite, ...) or use the sql
+command in the Bacula console:
+
+\footnotesize
+\begin{verbatim}
+update Media set VolStatus='Recycle';
+\end{verbatim}
+\normalsize
+
+Bacula will then ignore the data already stored on the tapes and just re-use
+each tape without further objection.

+\index[general]{Backing up ACLs on ext3 or XFS filesystems }
+
+This tip comes from Volker Sauer.
+
+Note, this tip was given prior to implementation of ACLs in Bacula (version
+1.34.5). It is left here because dumping/displaying ACLs can still be useful
+in testing/verifying that Bacula is backing up and restoring your ACLs
+properly. Please see the
+\ilink{aclsupport}{ACLSupport} FileSet option in the
+configuration chapter of this manual.
+
+For example, you could dump the ACLs to a file with a script similar to the
+following:
+
+\footnotesize
+\begin{verbatim}
+#!/bin/sh
+BACKUP_DIRS="/foo /bar"
+STORE_ACL=/root/acl-backup
+umask 077
+for i in $BACKUP_DIRS; do
+ cd $i /usr/bin/getfacl -R --skip-base .>$STORE_ACL/${i//\//_}
+done
+\end{verbatim}
+\normalsize
+
+Then use Bacula to backup {\bf /root/acl-backup}.
+
+The ACLs could be restored using Bacula to the {\bf /root/acl-backup} file,
+then restored to your system using:
+
+\footnotesize
+\begin{verbatim}
+setfacl --restore/root/acl-backup

+\section{Total Automation of Bacula Tape Handling}
+\label{automate}
+\index[general]{Handling!Total Automation of Bacula Tape }
+\index[general]{Total Automation of Bacula Tape Handling }
+
+This tip was provided by Alexander Kuehn.
+
+\elink{Bacula}{\url{http://www.bacula.org/}} is a really nice backup program except
+that the manual tape changing requires user interaction with the bacula
+console.
+
+Fortunately I can fix this.
+NOTE!!! This suggestion applies for people who do *NOT* have tape autochangers
+and must change tapes manually.!!!!!
+
+Bacula supports a variety of tape changers through the use of mtx-changer
+scripts/programs. This highly flexible approach allowed me to create
+\elink{this shell script}{\url{http://www.bacula.org/en/rel-manual/mtx-changer.txt}} which does the following:
+% TODO: We need to include this in book appendix and point to it.
+% TODO:
+Whenever a new tape is required it sends a mail to the operator to insert the
+new tape. Then it waits until a tape has been inserted, sends a mail again to
+say thank you and let's bacula continue its backup.
+So you can schedule and run backups without ever having to log on or see the
+console.
+To make the whole thing work you need to create a Device resource which looks
+something like this ("Archive Device", "Maximum Changer Wait", "Media
+Type" and "Label media" may have different values):
+
+\footnotesize
+\begin{verbatim}
+Device {
+ Name=DDS3
+ Archive Device = # use yours not mine! ;)/dev/nsa0
+ Changer Device = # not really required/dev/nsa0
+ Changer Command = "# use this (maybe change the path)!
+ /usr/local/bin/mtx-changer %o %a %S"
+ Maximum Changer Wait = 3d # 3 days in seconds
+ AutomaticMount = yes; # mount on start
+ AlwaysOpen = yes; # keep device locked
+ Media Type = DDS3 # it's just a name
+ RemovableMedia = yes; #
+ Offline On Unmount = Yes; # keep this too
+ Label media = Yes; #
+}
+\end{verbatim}
+\normalsize
+
+As the script has to emulate the complete wisdom of a mtx-changer it has an
+internal "database" containing where which tape is stored, you can see this on
+the following line:
+
+\footnotesize
+\begin{verbatim}
+labels="VOL-0001 VOL-0002 VOL-0003 VOL-0004 VOL-0005 VOL-0006
+VOL-0007 VOL-0008 VOL-0009 VOL-0010 VOL-0011 VOL-0012"
+\end{verbatim}
+\normalsize
+
+The above should be all on one line, and it effectively tells Bacula that
+volume "VOL-0001" is located in slot 1 (which is our lowest slot), that
+volume "VOL-0002" is located in slot 2 and so on..
+The script also maintains a logfile (/var/log/mtx.log) where you can monitor
+its operation.
+
+\section{Running Concurrent Jobs}
+\label{ConcurrentJobs}
+\index[general]{Jobs!Running Concurrent}
+\index[general]{Running Concurrent Jobs}
+\index[general]{Concurrent Jobs}
+
+Bacula can run multiple concurrent jobs, but the default configuration files
+do not enable it. Using the {\bf Maximum Concurrent Jobs} directive, you
+can configure how many and which jobs can be run simultaneously.
+The Director's default value for {\bf Maximum Concurrent Jobs} is "1".
+
+To initially setup concurrent jobs you need to define {\bf Maximum Concurrent Jobs} in
+the Director's configuration file (bacula-dir.conf) in the
+Director, Job, Client, and Storage resources.
+
+Additionally the File daemon, and the Storage daemon each have their own
+{\bf Maximum Concurrent Jobs} directive that sets the overall maximum
+number of concurrent jobs the daemon will run. The default for both the
+File daemon and the Storage daemon is "20".
+
+For example, if you want two different jobs to run simultaneously backing up
+the same Client to the same Storage device, they will run concurrently only if
+you have set {\bf Maximum Concurrent Jobs} greater than one in the Director
+resource, the Client resource, and the Storage resource in bacula-dir.conf.
+
+We recommend that you read the \ilink{Data
+Spooling}{SpoolingChapter} of this manual first, then test your multiple
+concurrent backup including restore testing before you put it into
+production.
+
+Below is a super stripped down bacula-dir.conf file showing you the four
+places where the the file must be modified to allow the same job {\bf
+NightlySave} to run up to four times concurrently. The change to the Job
+resource is not necessary if you want different Jobs to run at the same time,
+which is the normal case.
+
+\footnotesize
+\begin{verbatim}
+#
+# Bacula Director Configuration file -- bacula-dir.conf
+#
+Director {
+ Name = rufus-dir
+ Maximum Concurrent Jobs = 4
+ ...

+ Name = "NightlySave"

+ Client = rufus-fd
+ Storage = File
+ ...
+}
+Client {
+ Name = rufus-fd
+ Maximum Concurrent Jobs = 4
+ ...

+\label{bimagemgr}
+\index[general]{Bimagemgr }
+
+{\bf bimagemgr} is a utility for those who backup to disk volumes in order to
+commit them to CDR disk, rather than tapes. It is a web based interface
+written in Perl and is used to monitor when a volume file needs to be burned to
+disk. It requires:
+
+\begin{itemize}
+\item A web server running on the bacula server
+\item A CD recorder installed and configured on the bacula server
+\item The cdrtools package installed on the bacula server.
+\item perl, perl-DBI module, and either DBD-MySQL DBD-SQLite or DBD-PostgreSQL modules
+ \end{itemize}
+
+DVD burning is not supported by {\bf bimagemgr} at this
+time, but both are planned for future releases.
+
+\subsection{bimagemgr installation}
+\index[general]{bimagemgr!Installation }
+\index[general]{bimagemgr Installation }
+
+Installation from tarball:
+% TODO: use itemized list for this?
+1. Examine the Makefile and adjust it to your configuration if needed.
+2. Edit config.pm to fit your configuration.
+3. Do 'make install' as root.
+4. Edit httpd.conf and change the Timeout value. The web server must not time
+out and close the connection before the burn process is finished. The exact
+value needed may vary depending upon your cd recorder speed and whether you are
+burning on the bacula server on on another machine across your network. In my
+case I set it to 1000 seconds. Restart httpd.
+5. Make sure that cdrecord is setuid root.
+% TODO: I am pretty sure cdrecord can be used without setuid root
+% TODO: as long as devices are setup correctly
+
+Installation from rpm package:
+% TODO: use itemized list for this?
+1. Install the rpm package for your platform.
+2. Edit /cgi-bin/config.pm to fit your configuration.
+3. Edit httpd.conf and change the Timeout value. The web server must not time
+out and close the connection before the burn process is finished. The exact
+value needed may vary depending upon your cd recorder speed and whether you are
+burning on the bacula server on on another machine across your network. In my
+case I set it to 1000 seconds. Restart httpd.
+4. Make sure that cdrecord is setuid root.
+
+For bacula systems less than 1.36:
+% TODO: use itemized list for this?
+1. Edit the configuration section of config.pm to fit your configuration.
+2. Run /etc/bacula/create\_cdimage\_table.pl from a console on your bacula
+server (as root) to add the CDImage table to your bacula database.
+
+Accessing the Volume files:
+The Volume files by default have permissions 640 and can only be read by root.
+The recommended approach to this is as follows (and only works if bimagemgr and
+apache are running on the same host as bacula.
+
+For bacula-1.34 or 1.36 installed from tarball -
+% TODO: use itemized list for this?
+1. Create a new user group bacula and add the user apache to the group for
+Red Hat or Mandrake systems. For SuSE systems add the user wwwrun to the
+bacula group.
+2. Change ownership of all of your Volume files to root.bacula
+3. Edit the /etc/bacula/bacula startup script and set SD\_USER=root and
+SD\_GROUP=bacula. Restart bacula.
+
+Note: step 3 should also be done in /etc/init.d/bacula-sd but released versions
+of this file prior to 1.36 do not support it. In that case it would be necessary after
+a reboot of the server to execute '/etc/bacula/bacula restart'.
+
+For bacula-1.38 installed from tarball -
+% TODO: use itemized list for this?
+1. Your configure statement should include:
+% TODO: fix formatting here
+ --with-dir-user=bacula
+ --with-dir-group=bacula
+ --with-sd-user=bacula
+ --with-sd-group=disk
+ --with-fd-user=root
+ --with-fd-group=bacula
+2. Add the user apache to the bacula group for Red Hat or Mandrake systems.
+For SuSE systems add the user wwwrun to the bacula group.
+3. Check/change ownership of all of your Volume files to root.bacula
+
+For bacula-1.36 or bacula-1.38 installed from rpm -
+% TODO: use itemized list for this?
+1. Add the user apache to the group bacula for Red Hat or Mandrake systems.
+For SuSE systems add the user wwwrun to the bacula group.
+2. Check/change ownership of all of your Volume files to root.bacula
+
+bimagemgr installed from rpm > 1.38.9 will add the web server user to the
+bacula group in a post install script. Be sure to edit the configuration
+information in config.pm after installation of rpm package.
+
+bimagemgr will now be able to read the Volume files but they are still not
+world readable.
+
+If you are running bimagemgr on another host (not recommended) then you will
+need to change the permissions on all of your backup volume files to 644 in
+order to access them via nfs share or other means. This approach should only
+be taken if you are sure of the security of your environment as it exposes
+the backup Volume files to world read.
+
+\subsection{bimagemgr usage}
+\index[general]{bimagemgr!Usage }
+\index[general]{bimagemgr Usage }
+
+Calling the program in your web browser, e.g. {\tt
+http://localhost/cgi-bin/bimagemgr.pl} will produce a display as shown below
+% TODO: use tex to say figure number
+in Figure 1. The program will query the bacula database and display all volume
+files with the date last written and the date last burned to disk. If a volume
+needs to be burned (last written is newer than last burn date) a "Burn"
+button will be displayed in the rightmost column.
+
+\addcontentsline{lof}{figure}{Bacula CD Image Manager}
+\includegraphics{\idir bimagemgr1.eps} \\Figure 1
+% TODO: use tex to say figure number
+
+Place a blank CDR disk in your recorder and click the "Burn" button. This will
+cause a pop up window as shown in Figure 2 to display the burn progress.
+% TODO: use tex to say figure number
+
+\addcontentsline{lof}{figure}{Bacula CD Image Burn Progress Window}
+\includegraphics{\idir bimagemgr2.eps} \\Figure 2
+% TODO: use tex to say figure number
+
+When the burn finishes the pop up window will display the results of cdrecord
+% TODO: use tex to say figure number
+as shown in Figure 3. Close the pop up window and refresh the main window. The
+last burn date will be updated and the "Burn" button for that volume will
+disappear. Should you have a failed burn you can reset the last burn date of
+that volume by clicking its "Reset" link.
+
+\addcontentsline{lof}{figure}{Bacula CD Image Burn Results}
+\includegraphics{\idir bimagemgr3.eps} \\Figure 3
+% TODO: use tex to say figure number
+
+In the bottom row of the main display window are two more buttons labeled
+"Burn Catalog" and "Blank CDRW". "Burn Catalog" will place a copy of
+your bacula catalog on a disk. If you use CDRW disks rather than CDR then
+"Blank CDRW" allows you to erase the disk before re-burning it. Regularly
+committing your backup volume files and your catalog to disk with {\bf
+bimagemgr} ensures that you can rebuild easily in the event of some disaster
+on the bacula server itself.

+
+ Version 1.2, November 2002
+
+
+ Copyright \copyright 2000,2001,2002 Free Software Foundation, Inc.
+
+ \bigskip
+
+ 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+
+ \bigskip
+
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+\end{center}
+
+
+\begin{center}
+{\bf\large Preamble}
+\end{center}
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document "free" in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of "copyleft", which means that derivative
+works of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does. But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book. We recommend this License
+principally for works whose purpose is instruction or reference.
+
+
+\begin{center}
+{\Large\bf 1. APPLICABILITY AND DEFINITIONS}
+\end{center}
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License. Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein. The \textbf{"Document"}, below,
+refers to any such manual or work. Any member of the public is a
+licensee, and is addressed as \textbf{"you"}. You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A \textbf{"Modified Version"} of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A \textbf{"Secondary Section"} is a named appendix or a front-matter section of
+the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall subject
+(or to related matters) and contains nothing that could fall directly
+within that overall subject. (Thus, if the Document is in part a
+textbook of mathematics, a Secondary Section may not explain any
+mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The \textbf{"Invariant Sections"} are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License. If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant. The Document may contain zero
+Invariant Sections. If the Document does not identify any Invariant
+Sections then there are none.
+
+The \textbf{"Cover Texts"} are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License. A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A \textbf{"Transparent"} copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text. A copy that is not "Transparent" is called \textbf{"Opaque"}.
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input format, SGML
+or XML using a publicly available DTD, and standard-conforming simple
+HTML, PostScript or PDF designed for human modification. Examples of
+transparent image formats include PNG, XCF and JPG. Opaque formats
+include proprietary formats that can be read and edited only by
+proprietary word processors, SGML or XML for which the DTD and/or
+processing tools are not generally available, and the
+machine-generated HTML, PostScript or PDF produced by some word
+processors for output purposes only.
+
+The \textbf{"Title Page"} means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, "Title Page" means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+A section \textbf{"Entitled XYZ"} means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language. (Here XYZ stands for a
+specific section name mentioned below, such as \textbf{"Acknowledgements"},
+\textbf{"Dedications"}, \textbf{"Endorsements"}, or \textbf{"History"}.)
+To \textbf{"Preserve the Title"}
+of such a section when you modify the Document means that it remains a
+section "Entitled XYZ" according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document. These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+
+\begin{center}
+{\Large\bf 2. VERBATIM COPYING}
+\end{center}
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+
+\begin{center}
+{\Large\bf 3. COPYING IN QUANTITY}
+\end{center}
+
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+
+\begin{center}
+{\Large\bf 4. MODIFICATIONS}
+\end{center}
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+\begin{itemize}
+\item[A.]
+ Use in the Title Page (and on the covers, if any) a title distinct
+ from that of the Document, and from those of previous versions
+ (which should, if there were any, be listed in the History section
+ of the Document). You may use the same title as a previous version
+ if the original publisher of that version gives permission.
+
+\item[B.]
+ List on the Title Page, as authors, one or more persons or entities
+ responsible for authorship of the modifications in the Modified
+ Version, together with at least five of the principal authors of the
+ Document (all of its principal authors, if it has fewer than five),
+ unless they release you from this requirement.
+
+\item[C.]
+ State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+
+\item[D.]
+ Preserve all the copyright notices of the Document.
+
+\item[E.]
+ Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+
+\item[F.]
+ Include, immediately after the copyright notices, a license notice
+ giving the public permission to use the Modified Version under the
+ terms of this License, in the form shown in the Addendum below.
+
+\item[G.]
+ Preserve in that license notice the full lists of Invariant Sections
+ and required Cover Texts given in the Document's license notice.
+
+\item[H.]
+ Include an unaltered copy of this License.
+
+\item[I.]
+ Preserve the section Entitled "History", Preserve its Title, and add
+ to it an item stating at least the title, year, new authors, and
+ publisher of the Modified Version as given on the Title Page. If
+ there is no section Entitled "History" in the Document, create one
+ stating the title, year, authors, and publisher of the Document as
+ given on its Title Page, then add an item describing the Modified
+ Version as stated in the previous sentence.
+
+\item[J.]
+ Preserve the network location, if any, given in the Document for
+ public access to a Transparent copy of the Document, and likewise
+ the network locations given in the Document for previous versions
+ it was based on. These may be placed in the "History" section.
+ You may omit a network location for a work that was published at
+ least four years before the Document itself, or if the original
+ publisher of the version it refers to gives permission.
+
+\item[K.]
+ For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the section all
+ the substance and tone of each of the contributor acknowledgements
+ and/or dedications given therein.
+
+\item[L.]
+ Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section titles.
+
+\item[M.]
+ Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+
+\item[N.]
+ Do not retitle any existing section to be Entitled "Endorsements"
+ or to conflict in title with any Invariant Section.
+
+\item[O.]
+ Preserve any Warranty Disclaimers.
+\end{itemize}
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled "Endorsements", provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+
+\begin{center}
+{\Large\bf 5. COMBINING DOCUMENTS}
+\end{center}
+
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled "History"
+in the various original documents, forming one section Entitled
+"History"; likewise combine any sections Entitled "Acknowledgements",
+and any sections Entitled "Dedications". You must delete all sections
+Entitled "Endorsements".
+
+\begin{center}
+{\Large\bf 6. COLLECTIONS OF DOCUMENTS}
+\end{center}
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+
+\begin{center}
+{\Large\bf 7. AGGREGATION WITH INDEPENDENT WORKS}
+\end{center}
+
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an "aggregate" if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+
+\begin{center}
+{\Large\bf 8. TRANSLATION}
+\end{center}
+
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers. In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled "Acknowledgements",
+"Dedications", or "History", the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+
+\begin{center}
+{\Large\bf 9. TERMINATION}
+\end{center}
+
+
+You may not copy, modify, sublicense, or distribute the Document except
+as expressly provided for under this License. Any other attempt to
+copy, modify, sublicense or distribute the Document is void, and will
+automatically terminate your rights under this License. However,
+parties who have received copies, or rights, from you under this
+License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+
+\begin{center}
+{\Large\bf 10. FUTURE REVISIONS OF THIS LICENSE}
+\end{center}
+
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns. See
+http://www.gnu.org/copyleft/.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation. If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.
+
+
+\begin{center}
+{\Large\bf ADDENDUM: How to use this License for your documents}
+% TODO: this is too long for table of contents
+\end{center}
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+\bigskip
+\begin{quote}
+ Copyright \copyright YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.2
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
+ A copy of the license is included in the section entitled "GNU
+ Free Documentation License".
+\end{quote}
+\bigskip
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the "with...Texts." line with this:
+
+\bigskip
+\begin{quote}
+ with the Invariant Sections being LIST THEIR TITLES, with the
+ Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
+\end{quote}
+\bigskip
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

+# ___________________
+#
+# For the multiple-index style, each index is identified by the ref argument to \newindex, \index,
+# and \printindex. A default index is allowed, which is indicated by omitting the optional
+# argument. The default index does not require a \newindex command. As \index commands
+# are encountered, their entries are stored according
+# to the ref argument. When the \printindex command is encountered, the stored index
+# entries for that argument are retrieved and printed. The title for each index is taken
+# from the last argument in the \newindex command.
+# While processing \index and \printindex commands, if no argument is given the index entries
+# are built into a default index. The title of the default index is simply "Index".
+# This makes the difference between single- and multiple-index processing trivial.
+#
+# Another method can be used by omitting the \printindex command and just using \include to
+# pull in index files created by the makeindex program. These files will start with
+# \begin{theindex}. This command is used to determine where to print the index. Using this
+# approach, the indices will be output in the same order as the newindex commands were
+# originally found (see below). Using a combination of \printindex and \include{indexfile} has not
+# been tested and may produce undesireable results.
+#
+# The index data are stored in a hash for later sorting and output. As \printindex
+# commands are handled, the order in which they were found in the tex filea is saved,
+# associated with the ref argument to \printindex.
+#
+# We use the original %index hash to store the index data into. We append a \002 followed by the
+# name of the index to isolate the entries in different indices from each other. This is necessary
+# so that different indices can have entries with the same name. For the default index, the \002 is
+# appended without the name.
+#
+# Since the index order in the output cannot be determined if the \include{indexfile}
+# command is used, the order will be assumed from the order in which the \newindex
+# commands were originally seen in the TeX files. This order is saved as well as the
+# order determined from any printindex{ref} commands. If \printindex commnads are used
+# to specify the index output, that order will be used. If the \include{idxfile} command
+# is used, the order of the original newindex commands will be used. In this case the
+# default index will be printed last since it doesn't have a corresponding \newindex
+# command and its order cannot be determined. Mixing \printindex and \include{idxfile}
+# commands in the same file is likely to produce less than satisfactory results.
+#
+#
+# The hash containing index data is named %indices. It contains the following data:
+#{
+# 'title' => {
+# $ref1 => $indextitle ,
+# $ref2 => $indextitle ,
+# ...
+# },
+# 'newcmdorder' => [ ref1, ref2, ..., * ], # asterisk indicates the position of the default index.
+# 'printindorder' => [ ref1, ref2, ..., * ], # asterisk indicates the position of the default index.

+\chapter{Volume Utility Tools}
+\label{_UtilityChapter}
+\index[general]{Volume Utility Tools}
+\index[general]{Tools!Volume Utility}
+
+This document describes the utility programs written to aid Bacula users and
+developers in dealing with Volumes external to Bacula.
+
+\section{Specifying the Configuration File}
+\index[general]{Specifying the Configuration File}
+
+Starting with version 1.27, each of the following programs requires a valid
+Storage daemon configuration file (actually, the only part of the
+configuration file that these programs need is the {\bf Device} resource
+definitions). This permits the programs to find the configuration parameters
+for your archive device (generally a tape drive). By default, they read {\bf
+bacula-sd.conf} in the current directory, but you may specify a different
+configuration file using the {\bf -c} option.
+
+
+\section{Specifying a Device Name For a Tape}
+\index[general]{Tape!Specifying a Device Name For a}
+\index[general]{Specifying a Device Name For a Tape}
+
+Each of these programs require a {\bf device-name} where the Volume can be
+found. In the case of a tape, this is the physical device name such as {\bf
+/dev/nst0} or {\bf /dev/rmt/0ubn} depending on your system. For the program to
+work, it must find the identical name in the Device resource of the
+configuration file. See below for specifying Volume names.
+
+Please note that if you have Bacula running and you ant to use
+one of these programs, you will either need to stop the Storage daemon, or
+{\bf unmount} any tape drive you want to use, otherwise the drive
+will {\bf busy} because Bacula is using it.
+
+
+\section{Specifying a Device Name For a File}
+\index[general]{File!Specifying a Device Name For a}
+\index[general]{Specifying a Device Name For a File}
+
+If you are attempting to read or write an archive file rather than a tape, the
+{\bf device-name} should be the full path to the archive location including
+the filename. The filename (last part of the specification) will be stripped
+and used as the Volume name, and the path (first part before the filename)
+must have the same entry in the configuration file. So, the path is equivalent
+to the archive device name, and the filename is equivalent to the volume name.
+
+
+\section{Specifying Volumes}
+\index[general]{Volumes!Specifying}
+\index[general]{Specifying Volumes}
+
+In general, you must specify the Volume name to each of the programs below
+(with the exception of {\bf btape}). The best method to do so is to specify a
+{\bf bootstrap} file on the command line with the {\bf -b} option. As part of
+the bootstrap file, you will then specify the Volume name or Volume names if
+more than one volume is needed. For example, suppose you want to read tapes
+{\bf tape1} and {\bf tape2}. First construct a {\bf bootstrap} file named say,
+{\bf list.bsr} which contains:
+
+\footnotesize
+\begin{verbatim}
+Volume=test1|test2
+\end{verbatim}
+\normalsize
+
+where each Volume is separated by a vertical bar. Then simply use:
+
+\footnotesize
+\begin{verbatim}
+./bls -b list.bsr /dev/nst0
+\end{verbatim}
+\normalsize
+
+In the case of Bacula Volumes that are on files, you may simply append volumes
+as follows:
+
+\footnotesize
+\begin{verbatim}
+./bls /tmp/test1\|test2
+\end{verbatim}
+\normalsize
+
+where the backslash (\textbackslash{}) was necessary as a shell escape to
+permit entering the vertical bar (|).
+
+And finally, if you feel that specifying a Volume name is a bit complicated
+with a bootstrap file, you can use the {\bf -V} option (on all programs except
+{\bf bcopy}) to specify one or more Volume names separated by the vertical bar
+(|). For example,
+
+\footnotesize
+\begin{verbatim}
+./bls -V Vol001 /dev/nst0
+\end{verbatim}
+\normalsize
+
+You may also specify an asterisk (*) to indicate that the program should
+accept any volume. For example:
+
+\footnotesize
+\begin{verbatim}
+./bls -V* /dev/nst0
+\end{verbatim}
+\normalsize
+
+\section{bls}
+\label{bls}
+\index[general]{bls}
+\index[general]{program!bls}
+
+{\bf bls} can be used to do an {\bf ls} type listing of a {\bf Bacula} tape or
+file. It is called:
+
+\footnotesize
+\begin{verbatim}
+Usage: bls [options] <device-name>
+ -b <file> specify a bootstrap file
+ -c <file> specify a config file
+ -d <level> specify debug level
+ -e <file> exclude list
+ -i <file> include list
+ -j list jobs
+ -k list blocks
+ (no j or k option) list saved files
+ -L dump label
+ -p proceed inspite of errors
+ -v be verbose
+ -V specify Volume names (separated by |)
+ -? print this message
+\end{verbatim}
+\normalsize
+
+For example, to list the contents of a tape:
+
+\footnotesize
+\begin{verbatim}
+./bls -V Volume-name /dev/nst0
+\end{verbatim}
+\normalsize
+
+Or to list the contents of a file:
+
+\footnotesize
+\begin{verbatim}
+./bls /tmp/Volume-name
+or
+./bls -V Volume-name /tmp
+\end{verbatim}
+\normalsize
+
+Note that, in the case of a file, the Volume name becomes the filename, so in
+the above example, you will replace the {\bf xxx} with the name of the volume
+(file) you wrote.
+
+Normally if no options are specified, {\bf bls} will produce the equivalent
+output to the {\bf ls -l} command for each file on the tape. Using other
+options listed above, it is possible to display only the Job records, only the
+tape blocks, etc. For example:
+
+\footnotesize
+\begin{verbatim}
+
+./bls /tmp/File002
+bls: butil.c:148 Using device: /tmp

+\subsection{Listing Jobs}
+\index[general]{Listing Jobs with bls}
+\index[general]{bls!Listing Jobs}
+
+If you are listing a Volume to determine what Jobs to restore, normally the
+{\bf -j} option provides you with most of what you will need as long as you
+don't have multiple clients. For example,
+
+\footnotesize
+\begin{verbatim}
+./bls -j -V Test1 -c stored.conf DDS-4
+bls: butil.c:258 Using device: "DDS-4" for reading.
+11-Jul 11:54 bls: Ready to read from volume "Test1" on device "DDS-4" (/dev/nst0).

+\end{verbatim}
+\normalsize
+
+shows a full save followed by two incremental saves.
+
+Adding the {\bf -v} option will display virtually all information that is
+available for each record:
+
+\subsection{Listing Blocks}
+\index[general]{Listing Blocks with bls}
+\index[general]{bls!Listing Blocks}
+
+Normally, except for debugging purposes, you will not need to list Bacula
+blocks (the "primitive" unit of Bacula data on the Volume). However, you can
+do so with:
+
+\footnotesize
+\begin{verbatim}
+./bls -k /tmp/File002
+bls: butil.c:148 Using device: /tmp
+Block: 1 size=64512
+Block: 2 size=64512
+...
+Block: 65 size=64512
+Block: 66 size=19195
+bls: Got EOF on device /tmp
+End of File on device
+\end{verbatim}
+\normalsize
+
+By adding the {\bf -v} option, you can get more information, which can be
+useful in knowing what sessions were written to the volume:
+
+\footnotesize
+\begin{verbatim}
+./bls -k -v /tmp/File002
+Volume Label:
+Id : Bacula 0.9 mortal
+VerNo : 10
+VolName : File002

+Block: 65 blen=64512 First rec FI=83 SessId=1 SessTim=1035062102 Strm=DATA rlen=1873
+Block: 66 blen=19195 First rec FI=83 SessId=1 SessTim=1035062102 Strm=DATA rlen=2973
+bls: Got EOF on device /tmp
+End of File on device
+\end{verbatim}
+\normalsize
+
+Armed with the SessionId and the SessionTime, you can extract just about
+anything.
+
+If you want to know even more, add a second {\bf -v} to the command line to
+get a dump of every record in every block.

+\section{bextract}
+\label{bextract}
+\index[general]{Bextract}
+\index[general]{program!bextract}
+
+If you find yourself using {\bf bextract}, you probably have done
+something wrong. For example, if you are trying to recover a file
+but are having problems, please see the \ilink {Restoring When Things Go
+Wrong}{database_restore} section of the Restore chapter of this manual.
+
+Normally, you will restore files by running a {\bf Restore} Job from the {\bf
+Console} program. However, {\bf bextract} can be used to extract a single file
+or a list of files from a Bacula tape or file. In fact, {\bf bextract} can be
+a useful tool to restore files to an empty system assuming you are able to
+boot, you have statically linked {\bf bextract} and you have an appropriate
+{\bf bootstrap} file.
+
+Please note that some of the current limitations of bextract are:
+
+\begin{enumerate}
+\item It cannot restore access control lists (ACL) that have been
+ backed up along with the file data.
+\item It cannot restore encrypted files.
+\item The command line length is relatively limited,
+ which means that you cannot enter a huge number of volumes. If you need to
+ enter more volumes than the command line supports, please use a bootstrap
+ file (see below).
+\end{enumerate}
+
+
+It is called:
+
+\footnotesize
+\begin{verbatim}
+
+Usage: bextract [-d debug_level] <device-name> <directory-to-store-files>
+ -b <file> specify a bootstrap file
+ -dnn set debug level to nn
+ -e <file> exclude list
+ -i <file> include list
+ -p proceed inspite of I/O errors
+ -V specify Volume names (separated by |)
+ -? print this message
+\end{verbatim}
+\normalsize
+
+where {\bf device-name} is the Archive Device (raw device name or full
+filename) of the device to be read, and {\bf directory-to-store-files} is a
+path prefix to prepend to all the files restored.
+
+NOTE: On Windows systems, if you specify a prefix of say d:/tmp, any file that
+would have been restored to {\bf c:/My Documents} will be restored to {\bf
+d:/tmp/My Documents}. That is, the original drive specification will be
+stripped. If no prefix is specified, the file will be restored to the original
+drive.
+
+\subsection{Extracting with Include or Exclude Lists}
+\index[general]{Lists!Extracting with Include or Exclude}
+\index[general]{Extracting with Include or Exclude Lists}
+
+Using the {\bf -e} option, you can specify a file containing a list of files
+to be excluded. Wildcards can be used in the exclusion list. This option will
+normally be used in conjunction with the {\bf -i} option (see below). Both the
+{\bf -e} and the {\bf -i} options may be specified at the same time as the
+{\bf -b} option. The bootstrap filters will be applied first, then the include
+list, then the exclude list.
+
+Likewise, and probably more importantly, with the {\bf -i} option, you can
+specify a file that contains a list (one file per line) of files and
+directories to include to be restored. The list must contain the full filename
+with the path. If you specify a path name only, all files and subdirectories
+of that path will be restored. If you specify a line containing only the
+filename (e.g. {\bf my-file.txt}) it probably will not be extracted because
+you have not specified the full path.
+
+For example, if the file {\bf include-list} contains:
+
+\footnotesize
+\begin{verbatim}
+/home/kern/bacula
+/usr/local/bin
+\end{verbatim}
+\normalsize
+
+Then the command:
+
+\footnotesize
+\begin{verbatim}
+./bextract -i include-list -V Volume /dev/nst0 /tmp
+\end{verbatim}
+\normalsize
+
+will restore from the Bacula archive {\bf /dev/nst0} all files and directories
+in the backup from {\bf /home/kern/bacula} and from {\bf /usr/local/bin}. The
+restored files will be placed in a file of the original name under the
+directory {\bf /tmp} (i.e. /tmp/home/kern/bacula/... and
+/tmp/usr/local/bin/...).
+
+\subsection{Extracting With a Bootstrap File}
+\index[general]{File!Extracting With a Bootstrap}
+\index[general]{Extracting With a Bootstrap File}
+
+The {\bf -b} option is used to specify a {\bf bootstrap} file containing the
+information needed to restore precisely the files you want. Specifying a {\bf
+bootstrap} file is optional but recommended because it gives you the most
+control over which files will be restored. For more details on the {\bf
+bootstrap} file, please see
+\ilink{Restoring Files with the Bootstrap File}{BootstrapChapter}
+chapter of this document. Note, you may also use a bootstrap file produced by
+the {\bf restore} command. For example:
+
+\footnotesize
+\begin{verbatim}
+./bextract -b bootstrap-file /dev/nst0 /tmp
+\end{verbatim}
+\normalsize
+
+The bootstrap file allows detailed specification of what files you want
+restored (extracted). You may specify a bootstrap file and include and/or
+exclude files at the same time. The bootstrap conditions will first be
+applied, and then each file record seen will be compared to the include and
+exclude lists.
+
+\subsection{Extracting From Multiple Volumes}
+\index[general]{Volumes!Extracting From Multiple}
+\index[general]{Extracting From Multiple Volumes}
+
+If you wish to extract files that span several Volumes, you can specify the
+Volume names in the bootstrap file or you may specify the Volume names on the
+command line by separating them with a vertical bar. See the section above
+under the {\bf bls} program entitled {\bf Listing Multiple Volumes} for more
+information. The same techniques apply equally well to the {\bf bextract}
+program or read the \ilink{Bootstrap}{BootstrapChapter}
+chapter of this document.
+
+\section{bscan}
+\label{bscan}
+\index[general]{bscan}
+\index[general]{program!bscan}
+
+If you find yourself using this program, you have probably done something
+wrong. For example, the best way to recover a lost or damaged Bacula
+database is to reload the database by using the bootstrap file that
+was written when you saved it (default bacula-dir.conf file).
+
+The {\bf bscan} program can be used to re-create a database (catalog)
+records from the backup information written to one or more Volumes.
+This is normally
+needed only if one or more Volumes have been pruned or purged from your
+catalog so that the records on the Volume are no longer in the catalog, or
+for Volumes that you have archived.
+
+With some care, it can also be used to synchronize your existing catalog with
+a Volume. Although we have never seen a case of bscan damaging a
+catalog, since bscan modifies your catalog, we recommend that
+you do a simple ASCII backup of your database before running {\bf bscan} just
+to be sure. See \ilink{Compacting Your Database}{CompactingMySQL} for
+the details of making a copy of your database.
+
+{\bf bscan} can also be useful in a disaster recovery situation, after the
+loss of a hard disk, if you do not have a valid {\bf bootstrap} file for
+reloading your system, or if a Volume has been recycled but not overwritten,
+you can use {\bf bscan} to re-create your database, which can then be used to
+{\bf restore} your system or a file to its previous state.
+
+It is called:
+
+\footnotesize
+\begin{verbatim}
+
+Usage: bscan [options] <bacula-archive>
+ -b bootstrap specify a bootstrap file
+ -c <file> specify configuration file
+ -d <nn> set debug level to nn
+ -m update media info in database
+ -n <name> specify the database name (default bacula)
+ -u <user> specify database user name (default bacula)
+ -P <password> specify database password (default none)
+ -h <host> specify database host (default NULL)
+ -p proceed inspite of I/O errors
+ -r list records
+ -s synchronize or store in database
+ -v verbose
+ -V <Volumes> specify Volume names (separated by |)
+ -w <dir> specify working directory (default from conf file)
+ -? print this message
+\end{verbatim}
+\normalsize
+
+If you are using MySQL or PostgreSQL, there is no need to supply a working
+directory since in that case, bscan knows where the databases are. However, if
+you have provided security on your database, you may need to supply either the
+database name ({\bf -b} option), the user name ({\bf -u} option), and/or the
+password ({\bf -p}) options.
+
+NOTE: before {\bf bscan} can work, it needs at least a bare bones valid
+database. If your database exists but some records are missing because
+they were pruned, then you are all set. If your database was lost or
+destroyed, then you must first ensure that you have the SQL program running
+(MySQL or PostgreSQL), then you must create the Bacula database (normally
+named bacula), and you must create the Bacula tables using the scripts in
+the {\bf cats} directory. This is explained in the
+\ilink{Installation}{CreateDatabase} chapter of the manual. Finally, before
+scanning into an empty database, you must start and stop the Director with
+the appropriate bacula-dir.conf file so that it can create the Client and
+Storage records which are not stored on the Volumes. Without these
+records, scanning is unable to connect the Job records to the proper
+client.
+
+Forgetting for the moment the extra complications of a full rebuild of
+your catalog, let's suppose that you did a backup to Volumes "Vol001"
+and "Vol002", then sometime later all records of one or both those
+Volumes were pruned or purged from the
+database. By using {\bf bscan} you can recreate the catalog entries for
+those Volumes and then use the {\bf restore} command in the Console to restore
+whatever you want. A command something like:
+
+\footnotesize
+\begin{verbatim}
+bscan -c bacula-sd.conf -v -V Vol001\|Vol002 /dev/nst0
+\end{verbatim}
+\normalsize
+
+will give you an idea of what is going to happen without changing
+your catalog. Of course, you may need to change the path to the Storage
+daemon's conf file, the Volume name, and your tape (or disk) device name. This
+command must read the entire tape, so if it has a lot of data, it may take a
+long time, and thus you might want to immediately use the command listed
+below. Note, if you are writing to a disk file, replace the device name with
+the path to the directory that contains the Volumes. This must correspond to
+the Archive Device in the conf file.
+
+Then to actually write or store the records in the catalog, add the {\bf -s}
+option as follows:
+
+\footnotesize
+\begin{verbatim}
+ bscan -s -m -c bacula-sd.conf -v -V Vol001\|Vol002 /dev/nst0
+\end{verbatim}
+\normalsize
+
+When writing to the database, if bscan finds existing records, it will
+generally either update them if something is wrong or leave them alone. Thus
+if the Volumes you are scanning are all or partially in the catalog already, no
+harm will be done to that existing data. Any missing data will simply be
+added.
+
+If you have multiple tapes, you should scan them with:
+
+\footnotesize
+\begin{verbatim}
+ bscan -s -m -c bacula-sd.conf -v -V Vol001\|Vol002\|Vol003 /dev/nst0
+\end{verbatim}
+\normalsize
+
+Since there is a limit on the command line length (511 bytes) accepted
+by {\bf bscan}, if you have too many Volumes, you will need to manually
+create a bootstrap file. See the \ilink{Bootstrap}{BootstrapChapter}
+chapter of this manual for more details, in particular the section
+entitled \ilink{Bootstrap for bscan}{bscanBootstrap}.
+
+You should, always try to specify the tapes in the order they are written.
+However, bscan can handle scanning tapes that are not sequential. Any
+incomplete records at the end of the tape will simply be ignored in that
+case. If you are simply repairing an existing catalog, this may be OK, but
+if you are creating a new catalog from scratch, it will leave your database
+in an incorrect state. If you do not specify all necessary Volumes on a
+single bscan command, bscan will not be able to correctly restore the
+records that span two volumes. In other words, it is much better to
+specify two or three volumes on a single bscan command rather than run
+bscan two or three times, each with a single volume.
+
+
+Note, the restoration process using bscan is not identical to the original
+creation of the catalog data. This is because certain data such as Client
+records and other non-essential data such
+as volume reads, volume mounts, etc is not stored on the Volume, and thus is
+not restored by bscan. The results of bscanning are, however, perfectly valid,
+and will permit restoration of any or all the files in the catalog using the
+normal Bacula console commands. If you are starting with an empty catalog
+and expecting bscan to reconstruct it, you may be a bit disappointed, but
+at a minimum, you must ensure that your bacula-dir.conf file is the same
+as what it previously was -- that is, it must contain all the appropriate
+Client resources so that they will be recreated in your new database {\bf
+before} running bscan. Normally when the Director starts, it will recreate
+any missing Client records in the catalog. Another problem you will have
+is that even if the Volumes (Media records) are recreated in the database,
+they will not have their autochanger status and slots properly set. As a
+result, you will need to repair that by using the {\bf update slots}
+command. There may be other considerations as well. Rather than
+bscanning, you should always attempt to recover you previous catalog
+backup.

+\index[general]{Catalog!Using bscan to Compare a Volume to an existing}
+\index[general]{Using bscan to Compare a Volume to an existing Catalog}
+
+If you wish to compare the contents of a Volume to an existing catalog without
+changing the catalog, you can safely do so if and only if you do {\bf not}
+specify either the {\bf -m} or the {\bf -s} options. However, at this time
+(Bacula version 1.26), the comparison routines are not as good or as thorough
+as they should be, so we don't particularly recommend this mode other than for
+testing.
+
+\subsection{Using bscan to Recreate a Catalog from a Volume}
+\index[general]{Volume!Using bscan to Recreate a Catalog from a Volume}
+\index[general]{Using bscan to Recreate a Catalog from a Volume}
+
+This is the mode for which {\bf bscan} is most useful. You can either {\bf
+bscan} into a freshly created catalog, or directly into your existing catalog
+(after having made an ASCII copy as described above). Normally, you should
+start with a freshly created catalog that contains no data.
+
+Starting with a single Volume named {\bf TestVolume1}, you run a command such
+as:
+
+\footnotesize
+\begin{verbatim}
+./bscan -V TestVolume1 -v -s -m -c bacula-sd.conf /dev/nst0
+\end{verbatim}
+\normalsize
+
+If there is more than one volume, simply append it to the first one separating
+it with a vertical bar. You may need to precede the vertical bar with a
+forward slash escape the shell -- e.g. {\bf
+TestVolume1\textbackslash{}|TestVolume2}. The {\bf -v} option was added for
+verbose output (this can be omitted if desired). The {\bf -s} option that
+tells {\bf bscan} to store information in the database. The physical device
+name {\bf /dev/nst0} is specified after all the options.
+
+{\bf} For example, after having done a full backup of a directory, then two
+incrementals, I reinitialized the SQLite database as described above, and
+using the bootstrap.bsr file noted above, I entered the following command:
+
+\footnotesize
+\begin{verbatim}
+./bscan -b bootstrap.bsr -v -s -c bacula-sd.conf /dev/nst0
+\end{verbatim}
+\normalsize
+
+which produced the following output:
+
+\footnotesize
+\begin{verbatim}
+bscan: bscan.c:182 Using Database: bacula, User: bacula
+bscan: bscan.c:673 Created Pool record for Pool: Default

+bscan: bscan.c:428 End of Volume. VolFiles=3 VolBlocks=57 VolBytes=10,027,437
+\end{verbatim}
+\normalsize
+
+The key points to note are that {\bf bscan} prints a line when each major
+record is created. Due to the volume of output, it does not print a line for
+each file record unless you supply the {\bf -v} option twice or more on the
+command line.
+
+In the case of a Job record, the new JobId will not normally be the same as
+the original Jobid. For example, for the first JobId above, the new JobId is
+1, but the original JobId is 2. This is nothing to be concerned about as it is
+the normal nature of databases. {\bf bscan} will keep everything straight.
+
+Although {\bf bscan} claims that it created a Client record for Client: Rufus
+three times, it was actually only created the first time. This is normal.
+
+You will also notice that it read an end of file after each Job (Got EOF on
+device ...). Finally the last line gives the total statistics for the bscan.
+
+If you had added a second {\bf -v} option to the command line, Bacula would
+have been even more verbose, dumping virtually all the details of each Job
+record it encountered.
+
+Now if you start Bacula and enter a {\bf list jobs} command to the console
+program, you will get:
+
+\footnotesize
+\begin{verbatim}
++-------+----------+------------------+------+-----+----------+----------+---------+
+| JobId | Name | StartTime | Type | Lvl | JobFiles | JobBytes | JobStat |
++-------+----------+------------------+------+-----+----------+----------+---------+
+| 1 | kernsave | 2002-10-07 14:59 | B | F | 84 | 4180207 | T |
+| 2 | kernsave | 2002-10-07 15:00 | B | I | 15 | 2170314 | T |
+| 3 | kernsave | 2002-10-07 15:01 | B | I | 33 | 3662184 | T |
++-------+----------+------------------+------+-----+----------+----------+---------+
+\end{verbatim}
+\normalsize
+
+which corresponds virtually identically with what the database contained
+before it was re-initialized and restored with bscan. All the Jobs and Files
+found on the tape are restored including most of the Media record. The Volume
+(Media) records restored will be marked as {\bf Full} so that they cannot be
+rewritten without operator intervention.
+
+It should be noted that {\bf bscan} cannot restore a database to the exact
+condition it was in previously because a lot of the less important information
+contained in the database is not saved to the tape. Nevertheless, the
+reconstruction is sufficiently complete, that you can run {\bf restore}
+against it and get valid results.
+
+An interesting aspect of restoring a catalog backup using {\bf bscan} is
+that the backup was made while Bacula was running and writing to a tape. At
+the point the backup of the catalog is made, the tape Bacula is writing to
+will have say 10 files on it, but after the catalog backup is made, there
+will be 11 files on the tape Bacula is writing. This there is a difference
+between what is contained in the backed up catalog and what is actually on
+the tape. If after restoring a catalog, you attempt to write on the same
+tape that was used to backup the catalog, Bacula will detect the difference
+in the number of files registered in the catalog compared to what is on the
+tape, and will mark the tape in error.
+
+There are two solutions to this problem. The first is possibly the simplest
+and is to mark the volume as Used before doing any backups. The second is
+to manually correct the number of files listed in the Media record of the
+catalog. This procedure is documented elsewhere in the manual and involves
+using the {\bf update volume} command in {\bf bconsole}.
+
+\subsection{Using bscan to Correct the Volume File Count}
+\index[general]{Using bscan to Correct the Volume File Count}
+\index[general]{Count!Using bscan to Correct the Volume File Count}
+
+If the Storage daemon crashes during a backup Job, the catalog will not be
+properly updated for the Volume being used at the time of the crash. This
+means that the Storage daemon will have written say 20 files on the tape, but
+the catalog record for the Volume indicates only 19 files.
+
+Bacula refuses to write on a tape that contains a different number of files
+from what is in the catalog. To correct this situation, you may run a {\bf
+bscan} with the {\bf -m} option (but {\bf without} the {\bf -s} option) to
+update only the final Media record for the Volumes read.
+
+\subsection{After bscan}
+\index[general]{After bscan}
+\index[general]{Bscan!After}
+
+If you use {\bf bscan} to enter the contents of the Volume into an existing
+catalog, you should be aware that the records you entered may be immediately
+pruned during the next job, particularly if the Volume is very old or had been
+previously purged. To avoid this, after running {\bf bscan}, you can manually
+set the volume status (VolStatus) to {\bf Read-Only} by using the {\bf update}
+command in the catalog. This will allow you to restore from the volume without
+having it immediately purged. When you have restored and backed up the data,
+you can reset the VolStatus to {\bf Used} and the Volume will be purged from
+the catalog.
+
+\section{bcopy}
+\label{bcopy}
+\index[general]{Bcopy}
+\index[general]{program!bcopy}
+
+The {\bf bcopy} program can be used to copy one {\bf Bacula} archive file to
+another. For example, you may copy a tape to a file, a file to a tape, a file
+to a file, or a tape to a tape. For tape to tape, you will need two tape
+drives. (a later version is planned that will buffer it to disk). In the
+process of making the copy, no record of the information written to the new
+Volume is stored in the catalog. This means that the new Volume, though it
+contains valid backup data, cannot be accessed directly from existing catalog
+entries. If you wish to be able to use the Volume with the Console restore
+command, for example, you must first bscan the new Volume into the catalog.

+
+One of the objectives of this program is to be able to recover as much data as
+possible from a damaged tape. However, the current version does not yet have
+this feature.
+
+As this is a new program, any feedback on its use would be appreciated. In

+\section{btape}
+\label{btape}
+\index[general]{Btape}
+\index[general]{program!btape}
+
+This program permits a number of elementary tape operations via a tty command
+interface. It works only with tapes and not with other kinds of Bacula
+storage media (DVD, File, ...). The {\bf test} command, described below,
+can be very useful for testing older tape drive compatibility problems.
+Aside from initial testing of tape drive compatibility with {\bf Bacula},
+{\bf btape} will be mostly used by developers writing new tape drivers.
+
+{\bf btape} can be dangerous to use with existing {\bf Bacula} tapes because
+it will relabel a tape or write on the tape if so requested regardless that
+the tape may contain valuable data, so please be careful and use it only on
+blank tapes.
+
+To work properly, {\bf btape} needs to read the Storage daemon's configuration
+file. As a default, it will look for {\bf bacula-sd.conf} in the current
+directory. If your configuration file is elsewhere, please use the {\bf -c}
+option to specify where.
+
+The physical device name must be specified on the command line, and this
+same device name must be present in the Storage daemon's configuration file
+read by {\bf btape}

+
+An important reason for this program is to ensure that a Storage daemon
+configuration file is defined so that Bacula will correctly read and write
+tapes.
+
+It is highly recommended that you run the {\bf test} command before running
+your first Bacula job to ensure that the parameters you have defined for your
+storage device (tape drive) will permit {\bf Bacula} to function properly. You
+only need to mount a blank tape, enter the command, and the output should be
+reasonably self explanatory. Please see the

+ weof write an EOF on the tape
+ wr write a single Bacula block
+ rr read a single record
+ qfill quick fill command
+\end{verbatim}
+\normalsize
+
+The most useful commands are:
+
+\begin{itemize}
+\item test -- test writing records and EOF marks and reading them back.
+\item fill -- completely fill a volume with records, then write a few records
+ on a second volume, and finally, both volumes will be read back.
+ This command writes blocks containing random data, so your drive will
+ not be able to compress the data, and thus it is a good test of
+ the real physical capacity of your tapes.
+\item readlabel -- read and dump the label on a Bacula tape.
+\item cap -- list the device capabilities as defined in the configuration
+ file and as perceived by the Storage daemon.
+ \end{itemize}
+
+The {\bf readlabel} command can be used to display the details of a Bacula
+tape label. This can be useful if the physical tape label was lost or damaged.
+
+
+In the event that you want to relabel a {\bf Bacula}, you can simply use the
+{\bf label} command which will write over any existing label. However, please
+note for labeling tapes, we recommend that you use the {\bf label} command in
+the {\bf Console} program since it will never overwrite a valid Bacula tape.

+\section{bsmtp}
+\label{bsmtp}
+\index[general]{Bsmtp}
+\index[general]{program!bsmtp}
+
+{\bf bsmtp} is a simple mail transport program that permits more flexibility
+than the standard mail programs typically found on Unix systems. It can even
+be used on Windows machines.
+
+It is called:
+
+\footnotesize
+\begin{verbatim}
+Usage: bsmtp [-f from] [-h mailhost] [-s subject] [-c copy] [recipient ...]
+ -c set the Cc: field
+ -dnn set debug level to nn
+ -f set the From: field
+ -h use mailhost:port as the bsmtp server
+ -l limit the lines accepted to nn
+ -s set the Subject: field
+ -? print this message.
+\end{verbatim}
+\normalsize
+
+If the {\bf -f} option is not specified, {\bf bsmtp} will use your userid. If
+the option {\bf -h} is not specified {\bf bsmtp} will use the value in the environment
+variable {\bf bsmtpSERVER} or if there is none {\bf localhost}. By default
+port 25 is used.
+
+If a line count limit is set with the {\bf -l} option, {\bf bsmtp} will
+not send an email with a body text exceeding that number of lines. This
+is especially useful for large restore job reports where the list of
+files restored might produce very long mails your mail-server would
+refuse or crash. However, be aware that you will probably suppress the
+job report and any error messages unless you check the log file written
+by the Director (see the messages resource in this manual for details).
+
+
+{\bf recipients} is a space separated list of email recipients.
+
+The body of the email message is read from standard input.
+
+An example of the use of {\bf bsmtp} would be to put the following statement
+in the {\bf Messages} resource of your {\bf bacula-dir.conf} file. Note, these
+commands should appear on a single line each.
+
+\footnotesize
+\begin{verbatim}
+ mailcommand = "/home/bacula/bin/bsmtp -h mail.domain.com -f \"\(Bacula\) %r\"
+ -s \"Bacula: %t %e of %c %l\" %r"
+ operatorcommand = "/home/bacula/bin/bsmtp -h mail.domain.com -f \"\(Bacula\) %r\"
+ -s \"Bacula: Intervention needed for %j\" %r"
+\end{verbatim}
+\normalsize
+
+Where you replace {\bf /home/bacula/bin} with the path to your {\bf Bacula}
+binary directory, and you replace {\bf mail.domain.com} with the fully
+qualified name of your bsmtp (email) server, which normally listens on port
+25. For more details on the substitution characters (e.g. \%r) used in the
+above line, please see the documentation of the
+\ilink{ MailCommand in the Messages Resource}{mailcommand}
+chapter of this manual.
+
+It is HIGHLY recommended that you test one or two cases by hand to make sure
+that the {\bf mailhost} that you specified is correct and that it will accept
+your email requests. Since {\bf bsmtp} always uses a TCP connection rather
+than writing in the spool file, you may find that your {\bf from} address is
+being rejected because it does not contain a valid domain, or because your
+message is caught in your spam filtering rules. Generally, you should specify
+a fully qualified domain name in the {\bf from} field, and depending on
+whether your bsmtp gateway is Exim or Sendmail, you may need to modify the
+syntax of the from part of the message. Please test.
+
+When running {\bf bsmtp} by hand, you will need to terminate the message by
+entering a ctl-d in column 1 of the last line.
+% TODO: is "column" the correct terminology for this?
+
+If you are getting incorrect dates (e.g. 1970) and you are
+running with a non-English language setting, you might try adding
+a LANG=''en\_US'' immediately before the bsmtp call.

+\section{dbcheck}
+\label{dbcheck}
+\index[general]{Dbcheck}
+\index[general]{program!dbcheck}
+{\bf dbcheck} is a simple program that will search for logical
+inconsistencies in the Bacula tables in your database, and optionally fix them.
+It is a database maintenance routine, in the sense that it can
+detect and remove unused rows, but it is not a database repair
+routine. To repair a database, see the tools furnished by the
+database vendor. Normally dbcheck should never need to be run,
+but if Bacula has crashed or you have a lot of Clients, Pools, or
+Jobs that you have removed, it could be useful.
+
+The {\bf dbcheck} program can be found in
+the {\bf \lt{}bacula-source\gt{}/src/tools} directory of the source
+distribution. Though it is built with the make process, it is not normally
+"installed".

+If the \textbf{-B} option is specified, dbcheck will print out catalog

+
+By entering 1 or 2, you can toggle the modify database flag (-f option) and
+the verbose flag (-v). It can be helpful and reassuring to turn off the modify
+database flag, then select one or more of the consistency checks (items 3
+through 9) to see what will be done, then toggle the modify flag on and re-run
+the check.
+
+The inconsistencies examined are the following:
+
+\begin{itemize}
+\item Duplicate filename records. This can happen if you accidentally run two
+ copies of Bacula at the same time, and they are both adding filenames
+ simultaneously. It is a rare occurrence, but will create an inconsistent
+ database. If this is the case, you will receive error messages during Jobs
+ warning of duplicate database records. If you are not getting these error
+ messages, there is no reason to run this check.
+\item Repair bad Filename records. This checks and corrects filenames that
+ have a trailing slash. They should not.
+\item Repair bad Path records. This checks and corrects path names that do
+ not have a trailing slash. They should.
+\item Duplicate path records. This can happen if you accidentally run two
+ copies of Bacula at the same time, and they are both adding filenames
+ simultaneously. It is a rare occurrence, but will create an inconsistent
+ database. See the item above for why this occurs and how you know it is
+ happening.
+\item Orphaned JobMedia records. This happens when a Job record is deleted
+ (perhaps by a user issued SQL statement), but the corresponding JobMedia
+ record (one for each Volume used in the Job) was not deleted. Normally, this
+ should not happen, and even if it does, these records generally do not take
+ much space in your database. However, by running this check, you can
+ eliminate any such orphans.
+\item Orphaned File records. This happens when a Job record is deleted
+ (perhaps by a user issued SQL statement), but the corresponding File record
+ (one for each Volume used in the Job) was not deleted. Note, searching for
+ these records can be {\bf very} time consuming (i.e. it may take hours) for a
+ large database. Normally this should not happen as Bacula takes care to
+ prevent it. Just the same, this check can remove any orphaned File records.
+ It is recommended that you run this once a year since orphaned File records
+ can take a large amount of space in your database. You might
+ want to ensure that you have indexes on JobId, FilenameId, and
+ PathId for the File table in your catalog before running this
+ command.
+\item Orphaned Path records. This condition happens any time a directory is
+ deleted from your system and all associated Job records have been purged.
+ During standard purging (or pruning) of Job records, Bacula does not check
+ for orphaned Path records. As a consequence, over a period of time, old
+ unused Path records will tend to accumulate and use space in your database.
+ This check will eliminate them. It is recommended that you run this
+ check at least once a year.
+\item Orphaned Filename records. This condition happens any time a file is
+ deleted from your system and all associated Job records have been purged.
+ This can happen quite frequently as there are quite a large number of files
+ that are created and then deleted. In addition, if you do a system update or
+ delete an entire directory, there can be a very large number of Filename
+ records that remain in the catalog but are no longer used.
+
+ During standard purging (or pruning) of Job records, Bacula does not check
+ for orphaned Filename records. As a consequence, over a period of time, old
+ unused Filename records will accumulate and use space in your database. This
+ check will eliminate them. It is strongly recommended that you run this check
+ at least once a year, and for large database (more than 200 Megabytes), it is
+ probably better to run this once every 6 months.
+\item Orphaned Client records. These records can remain in the database long
+ after you have removed a client.
+\item Orphaned Job records. If no client is defined for a job or you do not
+ run a job for a long time, you can accumulate old job records. This option
+ allow you to remove jobs that are not attached to any client (and thus
+ useless).
+\item All Admin records. This command will remove all Admin records,
+ regardless of their age.
+\item All Restore records. This command will remove all Restore records,
+ regardless of their age.
+\end{itemize}
+
+
+If you are using Mysql, dbcheck will ask you if you want to create temporary
+indexes to speed up orphaned Path and Filename elimination.
+
+Mostly for PostgreSQL users, we provide a pure SQL script dbcheck replacement
+in \url{examples/database/dbcheck.sql} that works with global queries instead
+of many small queries like dbcheck. Execution instructions are at the top of
+the script and you will need to type \texttt{COMMIT} at the end to validate
+modifications.
+
+If you are using bweb or brestore, don't eliminate orphaned Path, else you will
+have to rebuild \texttt{brestore\_pathvisibility} and
+\texttt{brestore\_pathhierarchy} indexes.
+
+By the way, I personally run dbcheck only where I have messed up
+my database due to a bug in developing Bacula code, so normally
+you should never need to run dbcheck in spite of the
+recommendations given above, which are given so that users don't
+waste their time running dbcheck too often.

+\section{bregex}
+\label{bregex}
+\index[general]{bregex}
+\index[general]{program!bregex}
+
+{\bf bregex} is a simple program that will allow you to test
+regular expressions against a file of data. This can be useful
+because the regex libraries on most systems differ, and in
+addition, regex expressions can be complicated.
+
+{\bf bregex} is found in the src/tools directory and it is
+normally installed with your system binaries. To run it, use:
+
+\begin{verbatim}
+Usage: bregex [-d debug_level] -f <data-file>
+ -f specify file of data to be matched
+ -l suppress line numbers
+ -n print lines that do not match
+ -? print this message.
+\end{verbatim}
+
+The \lt{}data-file\gt{} is a filename that contains lines
+of data to be matched (or not) against one or more patterns.
+When the program is run, it will prompt you for a regular
+expression pattern, then apply it one line at a time against
+the data in the file. Each line that matches will be printed
+preceded by its line number. You will then be prompted again
+for another pattern.
+
+Enter an empty line for a pattern to terminate the program. You
+can print only lines that do not match by using the -n option,
+and you can suppress printing of line numbers with the -l option.
+
+This program can be useful for testing regex expressions to be
+applied against a list of filenames.
+

+
+{\bf bwild} is a simple program that will allow you to test
+wild-card expressions against a file of data.
+
+{\bf bwild} is found in the src/tools directory and it is
+normally installed with your system binaries. To run it, use:
+
+\begin{verbatim}
+Usage: bwild [-d debug_level] -f <data-file>
+ -f specify file of data to be matched
+ -l suppress line numbers
+ -n print lines that do not match
+ -? print this message.
+\end{verbatim}
+
+The \lt{}data-file\gt{} is a filename that contains lines
+of data to be matched (or not) against one or more patterns.
+When the program is run, it will prompt you for a wild-card
+pattern, then apply it one line at a time against
+the data in the file. Each line that matches will be printed
+preceded by its line number. You will then be prompted again
+for another pattern.
+
+Enter an empty line for a pattern to terminate the program. You
+can print only lines that do not match by using the -n option,
+and you can suppress printing of line numbers with the -l option.
+
+This program can be useful for testing wild expressions to be
+applied against a list of filenames.
+
+\section{testfind}
+\label{testfind}
+\index[general]{Testfind}
+\index[general]{program!testfind}
+
+{\bf testfind} permits listing of files using the same search engine that is
+used for the {\bf Include} resource in Job resources. Note, much of the
+functionality of this program (listing of files to be included) is present in
+the
+\ilink{estimate command}{estimate} in the Console program.
+
+The original use of testfind was to ensure that Bacula's file search engine
+was correct and to print some statistics on file name and path length.
+However, you may find it useful to see what bacula would do with a given {\bf
+Include} resource. The {\bf testfind} program can be found in the {\bf
+\lt{}bacula-source\gt{}/src/tools} directory of the source distribution.
+Though it is built with the make process, it is not normally "installed".
+
+It is called:
+
+\footnotesize
+\begin{verbatim}
+Usage: testfind [-d debug_level] [-] [pattern1 ...]
+ -a print extended attributes (Win32 debug)
+ -dnn set debug level to nn
+ - read pattern(s) from stdin
+ -? print this message.
+Patterns are used for file inclusion -- normally directories.
+Debug level>= 1 prints each file found.
+Debug level>= 10 prints path/file for catalog.
+Errors are always printed.
+Files/paths truncated is a number with len> 255.
+Truncation is only in the catalog.
+\end{verbatim}
+\normalsize
+
+Where a pattern is any filename specification that is valid within an {\bf
+Include} resource definition. If none is specified, {\bf /} (the root
+directory) is assumed. For example:
+
+\footnotesize
+\begin{verbatim}
+./testfind /bin
+\end{verbatim}
+\normalsize
+
+Would print the following:
+
+\footnotesize
+\begin{verbatim}
+Dir: /bin
+Reg: /bin/bash
+Lnk: /bin/bash2 -> bash
+Lnk: /bin/sh -> bash
+Reg: /bin/cpio
+Reg: /bin/ed
+Lnk: /bin/red -> ed
+Reg: /bin/chgrp
+...
+Reg: /bin/ipcalc
+Reg: /bin/usleep
+Reg: /bin/aumix-minimal
+Reg: /bin/mt
+Lnka: /bin/gawk-3.1.0 -> /bin/gawk
+Reg: /bin/pgawk
+Total files : 85
+Max file length: 13
+Max path length: 5
+Files truncated: 0
+Paths truncated: 0
+\end{verbatim}
+\normalsize
+
+Even though {\bf testfind} uses the same search engine as {\bf Bacula}, each
+directory to be listed, must be entered as a separate command line entry or
+entered one line at a time to standard input if the {\bf -} option was
+specified.
+
+Specifying a debug level of one (i.e. {\bf -d1}) on the command line will
+cause {\bf testfind} to print the raw filenames without showing the Bacula
+internal file type, or the link (if any). Debug levels of 10 or greater cause
+the filename and the path to be separated using the same algorithm that is
+used when putting filenames into the Catalog database.

+\end{enumerate}
+
+\section{Answers}
+\index[general]{Answers }
+
+\begin{enumerate}
+\item
+ \label{faq1}
+ {\bf How do I build Bacula for platform xxx?}
+ The bacula spec file contains defines to build for several platforms: \\
+ \\
+ Red Hat 7.x (rh7), Red Hat 8.0 (rh8), Red Hat 9 (rh9), \\
+ Fedora Core (fc1, fc3, fc4, fc5, fc6, fc7, fc8), \\
+ Whitebox Enterprise Linux 3.0 (wb3), \\
+ Red Hat Enterprise Linux (rhel3, rhel4, rhel5), \\
+ Mandrake 10.x (mdk), Mandriva 2006.x (mdv), \\
+ CentOS (centos3, centos4, centos5) \\
+ Scientific Linux (sl3, sl4, sl5) and \\
+ SuSE (su9, su10, su102, su103, su110). \\
+ \\
+ The package build is controlled by a mandatory define set at the beginning of the file. These defines basically just control the dependency information that gets coded into the finished rpm package as well
+ as any special configure options required. The platform define may be edited
+ in the spec file directly (by default all defines are set to 0 or "not set").
+ For example, to build the Red Hat 7.x package find the line in the spec file
+ which reads
+
+\footnotesize
+\begin{verbatim}
+ %define rh7 0
+
+\end{verbatim}
+\normalsize
+
+and edit it to read
+
+\footnotesize
+\begin{verbatim}
+ %define rh7 1
+
+\end{verbatim}
+\normalsize
+
+Alternately you may pass the define on the command line when calling rpmbuild:
+
+
+\footnotesize
+\begin{verbatim}
+ rpmbuild -ba --define "build_rh7 1" bacula.spec
+ rpmbuild --rebuild --define build_rh7 1" bacula-x.x.x-x.src.rpm
+
+\end{verbatim}
+\normalsize
+
+\item
+ \label{faq2}
+ {\bf How do I control which database support gets built?}
+ Another mandatory build define controls which database support is compiled,
+ one of build\_sqlite, build\_mysql or build\_postgresql. To get the MySQL
+ package and support either set the
+
+\footnotesize
+\begin{verbatim}
+ %define mysql 0
+ OR
+ %define mysql4 0
+ OR
+ %define mysql5 0
+
+\end{verbatim}
+\normalsize
+
+to
+
+\footnotesize
+\begin{verbatim}
+ %define mysql 1
+ OR
+ %define mysql4 1
+ OR
+ %define mysql5 1
+
+\end{verbatim}
+\normalsize
+
+in the spec file directly or pass it to rpmbuild on the command line:
+
+\footnotesize
+\begin{verbatim}
+ rpmbuild -ba --define "build_rh7 1" --define "build_mysql 1" bacula.spec
+ rpmbuild -ba --define "build_rh7 1" --define "build_mysql4 1" bacula.spec
+ rpmbuild -ba --define "build_rh7 1" --define "build_mysql5 1" bacula.spec
+
+\end{verbatim}
+\normalsize
+
+\item
+ \label{faq3}
+ {\bf What other defines are used?} \\
+ Three other building defines of note are the depkgs\_version, docs\_version and
+ \_rescuever identifiers. These two defines are set with each release and must
+ match the version of those sources that are being used to build the packages.
+ You would not ordinarily need to edit these. See also the Build Options section
+ below for other build time options that can be passed on the command line.
+\item
+ \label{faq4}
+ {\bf I'm getting errors about not having permission when I try to build the
+ packages. Do I need to be root?} \\
+ No, you do not need to be root and, in fact, it is better practice to
+ build rpm packages as a non-root user. Bacula packages are designed to
+ be built by a regular user but you must make a few changes on your
+ system to do this. If you are building on your own system then the
+ simplest method is to add write permissions for all to the build
+ directory (/usr/src/redhat/, /usr/src/RPM or /usr/src/packages).
+ To accomplish this, execute the following command as root:
+
+\footnotesize
+\begin{verbatim}
+ chmod -R 777 /usr/src/redhat
+ chmod -R 777 /usr/src/RPM
+ chmod -R 777 /usr/src/packages
+
+\end{verbatim}
+\normalsize
+
+If you are working on a shared system where you can not use the method
+above then you need to recreate the appropriate above directory tree with all
+of its subdirectories inside your home directory. Then create a file named
+
+{\tt .rpmmacros}
+
+in your home directory (or edit the file if it already exists)
+and add the following line:
+
+\footnotesize
+\begin{verbatim}
+ %_topdir /home/myuser/redhat
+ %_tmppath /tmp
+
+\end{verbatim}
+\normalsize
+
+Another handy directive for the .rpmmacros file if you wish to suppress the
+creation of debug rpm packages is:
+
+\footnotesize
+\begin{verbatim}
+ %debug_package %{nil}
+
+\end{verbatim}
+
+\normalsize
+
+\item
+ \label{faq5}
+ {\bf I'm building my own rpms but on all platforms and compiles I get an
+ unresolved dependency for something called /usr/afsws/bin/pagsh.} \\
+ This is a shell from the OpenAFS (Andrew File System). If you are
+ seeing this then you chose to include the docs/examples directory in
+ your package. One of the example scripts in this directory is a pagsh
+ script. Rpmbuild, when scanning for dependencies, looks at the shebang
+ line of all packaged scripts in addition to checking shared libraries.
+ To avoid this do not package the examples directory. If you are seeing
+ this problem you are building a very old bacula package as the examples
+ have been removed from the doc packaging.
+
+\item
+ \label{faq6}
+ {\bf I'm building my own rpms because you don't publish for my platform.
+ Can I get my packages released to sourceforge for other people to use?}
+ \\
+ Yes, contributions from users are accepted and appreciated. Please
+ examine the directory platforms/contrib-rpm in the source code for
+ further information.
+
+\item
+ \label{faq7}
+ {\bf Is there an easier way than sorting out all these command line options?}
+ \\
+ Yes, there is a gui wizard shell script which you can use to rebuild the
+ src rpm package. Look in the source archive for
+ platforms/contrib-rpm/rpm\_wizard.sh. This script will allow you to
+ specify build options using GNOME dialog screens. It requires zenity.
+
+\item
+ \label{faq8}
+ {\bf I just upgraded from 1.36.x to 1.38.x and now my director daemon
+won't start. It appears to start but dies silently and I get a "connection
+refused" error when starting the console. What is wrong?} \\
+ Beginning with 1.38 the rpm packages are configured to run the director
+ and storage daemons as a non-root user. The file daemon runs as user
+ root and group bacula, the storage daemon as user bacula and group disk,
+ and the director as user bacula and group bacula. If you are upgrading
+ you will need to change some file permissions for things to work.
+ Execute the following commands as root:
+
+\footnotesize
+\begin{verbatim}
+ chown bacula.bacula /var/bacula/*
+ chown root.bacula /var/bacula/bacula-fd.9102.state
+ chown bacula.disk /var/bacula/bacula-sd.9103.state
+
+\end{verbatim}
+\normalsize
+
+Further, if you are using File storage volumes rather than tapes those
+files will also need to have ownership set to user bacula and group bacula.
+
+\item
+ \label{faq9}
+ {\bf There are a lot of rpm packages. Which packages do I need for
+what?} \\
+For a bacula server you need to select the packsge based upon your
+preferred catalog database: one of bacula-mysql, bacula-postgresql or
+bacula-sqlite. If your system does not provide an mtx package you also
+need bacula-mtx to satisfy that dependancy. For a client machine you need
+only install bacula-client. Optionally, for either server or client
+machines, you may install a graphical console bacula-gconsole and/or
+bacula-wxconsole. The Bacula Administration Tool is installed with the
+bacula-bat package. One last package, bacula-updatedb is required only when
+upgrading a server more than one database revision level.
+
+
+
+\item {\bf Support for RHEL3/4/5, CentOS 3/4/5, Scientific Linux 3/4/5 and x86\_64}
+ \\
+ The examples below show
+ explicit build support for RHEL4 and CentOS 4. Build support
+ for x86\_64 has also been added.
+\end{enumerate}
+
+\footnotesize
+\begin{verbatim}
+Build with one of these 3 commands:
+
+rpmbuild --rebuild \
+ --define "build_rhel4 1" \
+ --define "build_sqlite 1" \
+ bacula-1.38.3-1.src.rpm
+
+rpmbuild --rebuild \

+
+rpmbuild --rebuild \
+ --define "build_rhel4 1" \

+ bacula-1.38.3-1.src.rpm
+
+For CentOS substitute '--define "build_centos4 1"' in place of rhel4.
+For Scientific Linux substitute '--define "build_sl4 1"' in place of rhel4.
+
+For 64 bit support add '--define "build_x86_64 1"'

+\section{RPM Install Problems}
+\index[general]{RPM Install Problems}
+In general the RPMs, once properly built should install correctly.
+However, when attempting to run the daemons, a number of problems
+can occur:
+\begin{itemize}
+\item Wrong /var/bacula Permissions \\
+ By default, the Director and Storage daemon do not run with
+ root permission. If the /var/bacula is owned by root, then it
+ is possible that the Director and the Storage daemon will not
+ be able to access this directory, which is used as the Working
+ Directory. To fix this, the easiest thing to do is:
+\begin{verbatim}
+ chown bacula:bacula /var/bacula
+\end{verbatim}
+ Note: as of 1.38.8 /var/bacula is installed root:bacula with
+ permissions 770.
+\item The Storage daemon cannot Access the Tape drive \\
+ This can happen in some older RPM releases where the Storage
+ daemon ran under userid bacula, group bacula. There are two
+ ways of fixing this: the best is to modify the /etc/init.d/bacula-sd
+ file so that it starts the Storage daemon with group "disk".
+ The second way to fix the problem is to change the permissions
+ of your tape drive (usually /dev/nst0) so that Bacula can access it.
+ You will probably need to change the permissions of the SCSI control
+ device as well, which is usually /dev/sg0. The exact names depend
+ on your configuration, please see the Tape Testing chapter for
+ more information on devices.
