+\item Bacula supports doing backups and restores to multiple

+   However, if you have backed up a job to multiple storage
+   devices, Bacula can do a restore from only one device, which
+   means that you will need to manually edit the bootstrap file
+   to split it into two restores if you split the backup across 
+   storage devices.
+\item Bacula cannot restore two different jobs in the same
+   restore if those jobs were run simultaneously, unless you had
+   data spooling turned on and the spool file held the full
+   contents of both jobs. In other terms, Bacula cannot restore
+   two jobs in the same restore if the jobs' data blocks were
+   intermixed on the backup medium. This poses no restrictions
+   for normal backup jobs even if they are run simultaneously.
