It is turned on by default, and if the +two Bacula components (Dir, FD, SD, bconsole) are both +version 6.6.0 or greater, by default, comm line compression +will be enabled. If for some reason, you do not want +comm line compression, you may disable it with the +following directive: + +\begin{lstlisting} +Comm Compression = no +\end{lstlisting} + +\smallskip +This directive can appear in the following resources: +bacula-dir.conf: Director; bacula-fd.conf Client (or FileDaemon); +bacula-sd.conf: Storage; bconsole.conf: Console; bat.conf: Console. + +\smallskip +In many cases, the volume of data transmitted across the +communications line can be reduced by a factor of three when +this directive is enabled (default). + +\subsection{Read Only Devices} +This version of Bacula permits defining a Storage deamon device +to be read-only. That is if this directive is specified and +enabled, the drive can only be used for read operations. +The the ReadOnly directive can be defined in any bacula-sd.conf +Device resource, and can be used to reserve one or more +drives for restores. An example is: + +\begin{lstlisting} +Read Only = yes +\end{lstlisting. + +\subsection{Catalog Performance Improvement} +There is a new Bacula database format (schema) in this version +of Bacula that eliminates the FileName table by placing the +Filename into the File record of the File table. The +update_xxx_catalog script will automatically update the +Bacula database format, but you should realize that for +very large databases (greater than 1GB), it may take some +time, and there are several different options for doing the +update: 1. Shudown the database and update it. 2. Update the +database while production jobs are running. See the Bacula Systems +White Paper on this subject. + +\smallskip +This change can provide very significant improvements in the +speed of metadata insertion into the database, and in some cases +(backup of large email servers) can significantly reduce the size +of the database. + \section{Bacula Enterprise 6.4.0} \subsection{Deduplication Optimized Volumes} This version of Bacula includes a new alternative (or additional)
