+\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:
+
+\footnotesize
+\begin{verbatim}
+Bootstrap records written to /home/kern/bacula/working/restore.bsr
+The job will require the following
+ Volume(s) Storage(s) SD Device(s)
+===========================================================================
+
+ DLT-19Jul02 Tape DLT8000
+ DLT-04Aug02 Tape DLT8000
+
+128401 files 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: Tape
+When: 2006-12-11 18:20:33
+Catalog: MyCatalog
+Priority: 10
+OK to run? (yes/mod/no):
+
+\end{verbatim}
+\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

+\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.

+\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.
