+This chapter presents the new features added to the development 3.0.3
+versions to be released as Bacula version 3.0.3 sometime in 2009.

+\section{File deduplication using Base jobs}
+
+A base job is sort of like a Full save except that you will want the FileSet to
+contain only files that are unlikely to change in the future (i.e.  a snapshot
+of most of your system after installing it).  After the base job has been run,
+when you are doing a Full save, you specify one or more Base jobs to be used.
+All files that have been backed up in the Base job/jobs but not modified will
+then be excluded from the backup.  During a restore, the Base jobs will be
+automatically pulled in where necessary.
+
+This is something none of the competition does, as far as we know (except
+perhaps BackupPC, which is a Perl program that saves to disk only).  It is big
+win for the user, it makes Bacula stand out as offering a unique optimization
+that immediately saves time and money.  Basically, imagine that you have 100
+nearly identical Windows or Linux machine containing the OS and user files.
+Now for the OS part, a Base job will be backed up once, and rather than making
+100 copies of the OS, there will be only one.  If one or more of the systems
+have some files updated, no problem, they will be automatically restored.
+
+A new Job directive \texttt{Base=Jobx, Joby...} permits to specify the list of
+files that will be used during Full backup as base.
+
+\begin{verbatim}
+Job {
+   Name = BackupLinux
+   Level= Base
+   ...
+}
+
+Job {
+   Name = BackupZog4
+   Base = BackupZog4, BackupLinux
+   Accurate = yes
+   ...
+}
+\end{verbatim}
+
+In this example, the job \texttt{BackupZog4} will use the most recent version of all
+files contained in \texttt{BackupZog4} and \texttt{BackupLinux} jobs. Base jobs should
+have run with \texttt{level=Base} to be used.
+
+This project was funded by Bacula Systems.
