+\item [Statistics Enhancements]
+
+If you (or you boss) want to have statistics on your backups, you could use
+some SQL stuffs on the Job table to report how many:
+\begin{itemize}
+\item jobs have run
+\item jobs have been successful
+\item files have been backuped
+\item ...
+\end{itemize}
+
+Theses statistics are accurate only if your job retention is greater than
+your statistic period. Ie, if jobs are purged from the catalog, you won't be
+able to use them.
+
+Now, you can configure bacula to copy Job records to a new JobStat table
+with the \textbf{Use Statistics = \lt{}yes|no\gt{}} Job directive.
+
+The \texttt{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{JobStat} 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.
+
+Theses statistics records aren't use for restore purpose, but mainly for
+capacity planning, billings, etc.
+
+\begin{verbatim}
+Job {
+  Name = ImportantBackup
+  Client = rufus-fd
+  ...
+  Use Statistics = yes
+}
+\end{verbatim}
