Consider that Bacula backs up to Volumes.  Volumes belong to Pools.  To
Bacula, Volumes can be tapes or disk (and other media).  There is no
difference to Bacula.  The format is the same.  The scheduling,
retention, etc, all the same.

I think more is written about tape because those particular sections of
the documentation was written before disk backup was implemented. I find
myself talking and writing about tapes more than disks.  This may be
because I backup to tape more than to disk.  These are unproven theories.
