+ Since beginning work on the Bacula project in January 2000
+ until now (October 2005), I have spent approximately $8000
+ per year for computers, tape drives, communications expenses,
+ electricity, software licenses, and other expenses. I am
+ pleased to have been able to afford these expenditures and
+ have no desire to have them reimbursed.
+ Bacula is now a fairly mature product, and to ensure its long
+ term servival, it should start to pay its own way.
+ <p>
+ As a consequence, it is now possible for you
+ to donate to the Bacula project.
+ All funds collected will be used to help further the Bacula project
+ by covering out of pocket expenses incurred by the project (no salaries).
+ <p>
+ The project actually has the following needs (approximate costs): <br>
+ Three Microsoft Visual C++ licenses: $3000<br>
+ Autochanger for FreeBSD testing: $3200<br>
+ Autochanger for Solaris testing: $3200<br>
+
+
+ <p>
+ Donations may not be US tax deductible as this is a individual
+ Bacula project account with PayPal.
+ <p>
+ If you are a government or for-profit corporation and cannot
+ make "donations", please consider paying a binary license
+ fee for any Bacula built binaries that you download. A reasonable
+ license fee would be:
+ <p>
+ <table>
+ <tr> <td>Number of Machines</td> <td>Fee</td></tr>
+ <tr> <td>1-10</td> <td>$10 per machine</td></tr>
+ <tr> <td>11-20</td> <td>$100 + $5.00 per machine over 10</td></tr>

+\index[general]{Performance!Database}
+\addcontentsline{toc}{subsection}{Database Performance Issues}
+
+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.
+
+For MySQL, what seems to be very important is to use the examine the
+my.cnf file. 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 even of a machine crash.
+There are many different ways that you can tune PostgreSQL, the
+following document discusses a few of them:

Every once and a while, someone asks why we need Differential
backups as long as Incremental backups pickup all changed files.

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.

+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

+cases, there are options that will permit you to disable to feature

+
+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 types 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 2 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 int 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.

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
versions are available and tested.
You may install and use SQLite version 3.x with Bacula by using:
-{\bf ./configure \verb:--:with-sqlite3}. However, our testing indicates
-that SQLite version 3.x is 4 to 10 times slower than version 2.8.16, and
-consquently, we do not recommend using it.
+{\bf ./configure \verb:--:with-sqlite3}. You should ensure that
+when the database is created that you have used
+\begin{verbatim}
+PRAGMA synchronous = NORMAL;
+\end{verbatim}
+otherwiset SQLite version 3.x is 4 to 10 times slower than version 2.8.16.
Installing and Configuring is quite easy.
