+\chapter{New Features in 5.2.2}
+This chapter presents the new features that have been added to the current
+Community version of Bacula that is now released.
+
+\section{Additions to RunScript variables}
+You can have access to Director name using \%D in your runscript
+command.
+
+\begin{verbatim}
+RunAfterJob = "/bin/echo Director=%D
+\end{verbatim}
+
+\chapter{New Features in 5.2.1}
+This chapter presents the new features were added in the
+Community release version 5.2.1.
+
+There are additional features (plugins) available in the Enterprise version
+that are described in another chapter. A subscription to Bacula Systems
+is required for the Enterprise version.
+
+\section{LZO Compression}
+
+LZO compression was added in the Unix File Daemon. From the user point of view,
+it works like the GZIP compression (just replace {\bf compression=GZIP} with
+{\bf compression=LZO}).
+
+For example:
+\begin{verbatim}
+Include {
+ Options { compression=LZO }
+ File = /home
+ File = /data
+}
+\end{verbatim}
+
+LZO provides much faster compression and decompression speed but lower
+compression ratio than GZIP. It is a good option when you backup to disk. For
+tape, the built-in compression may be a better option.
+
+LZO is a good altenative for GZIP1 when you don't want to slow down your
+backup. On a modern CPU it should be able to run almost as fast as:
+
+\begin{itemize}
+\item your client can read data from disk. Unless you have very fast disks like
+ SSD or large/fast RAID array.
+\item the data transfers between the file daemon and the storage daemon even on
+ a 1Gb/s link.
+\end{itemize}
+
+Note that bacula only use one compression level LZO1X-1.
+
+\medskip
+The code for this feature was contributed by Laurent Papier.
+
+\section{New Tray Monitor}
+
+Since the old integrated Windows tray monitor doesn't work with
+recent Windows versions, we have written a new Qt Tray Monitor that is available
+for both Linux and Windows. In addition to all the previous features,
+this new version allows you to run Backups from
+the tray monitor menu.

+ \label{fig:traymonitor1}
+ \caption{Run a Job through the new tray monitor}
+\end{figure}
+
+
+To be able to run a job from the tray monitor, you need to
+allow specific commands in the Director monitor console:
+\begin{verbatim}
+Console {
+ Name = win2003-mon
+ Password = "xxx"
+ CommandACL = status, .clients, .jobs, .pools, .storage, .filesets, .messages, run
+ ClientACL = *all* # you can restrict to a specific host
+ CatalogACL = *all*
+ JobACL = *all*
+ StorageACL = *all*
+ ScheduleACL = *all*
+ PoolACL = *all*
+ FileSetACL = *all*
+ WhereACL = *all*
+}
+\end{verbatim}
+
+\medskip
+This project was funded by Bacula Systems and is available with Bacula
+the Enterprise Edition and the Community Edition.
+
+\section{Purge Migration Job}
+
+The new {\bf Purge Migration Job} directive may be added to the Migration
+Job definition in the Director's configuration file. When it is enabled
+the Job that was migrated during a migration will be purged at
+the end of the migration job.
+
+For example:
+\begin{verbatim}
+Job {
+ Name = "migrate-job"
+ Type = Migrate
+ Level = Full
+ Client = localhost-fd
+ FileSet = "Full Set"
+ Messages = Standard
+ Storage = DiskChanger
+ Pool = Default
+ Selection Type = Job
+ Selection Pattern = ".*Save"
+...
+ Purge Migration Job = yes
+}
+\end{verbatim}
+
+\medskip
+
+This project was submited by Dunlap Blake; testing and documentation was funded
+by Bacula Systems.
+
+\section{Changes in Bvfs (Bacula Virtual FileSystem)}
+
+Bat has now a bRestore panel that uses Bvfs to display files and
+directories.
+
+\begin{figure}[htbp]
+ \centering
+ \includegraphics[width=12cm]{\idir bat-brestore}
+ \label{fig:batbrestore}
+ \caption{Bat Brestore Panel}
+\end{figure}
+
+the Bvfs module works correctly with BaseJobs, Copy and Migration jobs.
+
+\medskip
+This project was funded by Bacula Systems.
+
+\subsection*{General notes}
+
+\begin{itemize}
+\item All fields are separated by a tab
+\item You can specify \texttt{limit=} and \texttt{offset=} to list smoothly
+ records in very big directories
+\item All operations (except cache creation) are designed to run instantly
+\item At this time, Bvfs works faster on PostgreSQL than MySQL catalog. If you
+ can contribute new faster SQL queries we will be happy, else don't complain
+ about speed.
+\item The cache creation is dependent of the number of directories. As Bvfs
+ shares information accross jobs, the first creation can be slow
+\item All fields are separated by a tab
+\item Due to potential encoding problem, it's advised to allways use pathid in
+ queries.
+\end{itemize}
+
+\subsection*{Get dependent jobs from a given JobId}
+
+Bvfs allows you to query the catalog against any combination of jobs. You
+can combine all Jobs and all FileSet for a Client in a single session.
+
+To get all JobId needed to restore a particular job, you can use the
+\texttt{.bvfs\_get\_jobids} command.
+
+\begin{verbatim}
+.bvfs_get_jobids jobid=num [all]
+\end{verbatim}
+
+\begin{verbatim}
+.bvfs_get_jobids jobid=10
+1,2,5,10
+.bvfs_get_jobids jobid=10 all
+1,2,3,5,10
+\end{verbatim}
+
+In this example, a normal restore will need to use JobIds 1,2,5,10 to
+compute a complete restore of the system.
+
+With the \texttt{all} option, the Director will use all defined FileSet for
+this client.
+
+\subsection*{Generating Bvfs cache}
+
+The \texttt{.bvfs\_update} command computes the directory cache for jobs
+specified in argument, or for all jobs if unspecified.
+
+\begin{verbatim}
+.bvfs_update [jobid=numlist]
+\end{verbatim}
+
+Example:
+\begin{verbatim}
+.bvfs_update jobid=1,2,3
+\end{verbatim}
+
+You can run the cache update process in a RunScript after the catalog backup.
+
+\subsection*{Get all versions of a specific file}
+
+Bvfs allows you to find all versions of a specific file for a given Client with
+the \texttt{.bvfs\_version} command. To avoid problems with encoding, this
+function uses only PathId and FilenameId. The jobid argument is mandatory but
+unused.
+
+\begin{verbatim}
+.bvfs_versions client=filedaemon pathid=num filenameid=num jobid=1
+PathId FilenameId FileId JobId LStat Md5 VolName Inchanger
+PathId FilenameId FileId JobId LStat Md5 VolName Inchanger
+...
+\end{verbatim}
+
+Example:
+
+\begin{verbatim}
+.bvfs_versions client=localhost-fd pathid=1 fnid=47 jobid=1
+1 47 52 12 gD HRid IGk D Po Po A P BAA I A /uPgWaxMgKZlnMti7LChyA Vol1 1
+\end{verbatim}
+
+\subsection*{List directories}
+
+Bvfs allows you to list directories in a specific path.
+\begin{verbatim}
+.bvfs_lsdirs pathid=num path=/apath jobid=numlist limit=num offset=num
+PathId FilenameId FileId JobId LStat Path
+PathId FilenameId FileId JobId LStat Path
+PathId FilenameId FileId JobId LStat Path
+...
+\end{verbatim}
+
+You need to \texttt{pathid} or \texttt{path}. Using \texttt{path=""} will list
+``/'' on Unix and all drives on Windows. If FilenameId is 0, the record
+listed is a directory.
+
+\begin{verbatim}
+.bvfs_lsdirs pathid=4 jobid=1,11,12
+4 0 0 0 A A A A A A A A A A A A A A .
+5 0 0 0 A A A A A A A A A A A A A A ..
+3 0 0 0 A A A A A A A A A A A A A A regress/
+\end{verbatim}
+
+In this example, to list directories present in \texttt{regress/}, you can use
+\begin{verbatim}
+.bvfs_lsdirs pathid=3 jobid=1,11,12
+3 0 0 0 A A A A A A A A A A A A A A .
+4 0 0 0 A A A A A A A A A A A A A A ..
+2 0 0 0 A A A A A A A A A A A A A A tmp/
+\end{verbatim}
+
+\subsection*{List files}
+
+Bvfs allows you to list files in a specific path.
+\begin{verbatim}
+.bvfs_lsfiles pathid=num path=/apath jobid=numlist limit=num offset=num
+PathId FilenameId FileId JobId LStat Path
+PathId FilenameId FileId JobId LStat Path
+PathId FilenameId FileId JobId LStat Path
+...
+\end{verbatim}
+
+You need to \texttt{pathid} or \texttt{path}. Using \texttt{path=""} will list
+``/'' on Unix and all drives on Windows. If FilenameId is 0, the record listed
+is a directory.
+
+\begin{verbatim}
+.bvfs_lsfiles pathid=4 jobid=1,11,12
+4 0 0 0 A A A A A A A A A A A A A A .
+5 0 0 0 A A A A A A A A A A A A A A ..
+1 0 0 0 A A A A A A A A A A A A A A regress/
+\end{verbatim}
+
+In this example, to list files present in \texttt{regress/}, you can use
+\begin{verbatim}
+.bvfs_lsfiles pathid=1 jobid=1,11,12
+1 47 52 12 gD HRid IGk BAA I BMqcPH BMqcPE BMqe+t A titi
+1 49 53 12 gD HRid IGk BAA I BMqe/K BMqcPE BMqe+t B toto
+1 48 54 12 gD HRie IGk BAA I BMqcPH BMqcPE BMqe+3 A tutu
+1 45 55 12 gD HRid IGk BAA I BMqe/K BMqcPE BMqe+t B ficheriro1.txt
+1 46 56 12 gD HRie IGk BAA I BMqe/K BMqcPE BMqe+3 D ficheriro2.txt
+\end{verbatim}
+
+\subsection*{Restore set of files}
+
+Bvfs allows you to create a SQL table that contains files that you want to
+restore. This table can be provided to a restore command with the file option.
+
+\begin{verbatim}
+.bvfs_restore fileid=numlist dirid=numlist hardlink=numlist path=b2num
+OK
+restore file=?b2num ...
+\end{verbatim}
+
+To include a directory (with \texttt{dirid}), Bvfs needs to run a query to
+select all files. This query could be time consuming.
+
+\texttt{hardlink} list is always composed of a serie of two numbers (jobid,
+fileindex). This information can be found in the LinkFI field of the LStat
+packet.
+
+The \texttt{path} argument represents the name of the table that Bvfs will
+store results. The format of this table is \texttt{b2[0-9]+}. (Should start by
+b2 and followed by digits).
+
+Example:
+
+\begin{verbatim}
+.bvfs_restore fileid=1,2,3,4 hardlink=10,15,10,20 jobid=10 path=b20001
+OK
+\end{verbatim}
+
+\subsection*{Cleanup after Restore}
+
+To drop the table used by the restore command, you can use the
+\texttt{.bvfs\_cleanup} command.
+
+\begin{verbatim}
+.bvfs_cleanup path=b20001
+\end{verbatim}
+
+\subsection*{Clearing the BVFS Cache}
+
+To clear the BVFS cache, you can use the \texttt{.bvfs\_clear_cache} command.
+
+\begin{verbatim}
+.bvfs_clear_cache yes
+OK
+\end{verbatim}
+
