Is there a easy way to find files which _do_ exist, but don't have
corresponding entries in the database? In this case they'll be wasting
storage, and will never be expired.
An example of when this could happen is after the restore of the myth
database, when recordings have happened since the backup. In my case,
this can occur if I roll-back to a backup of my myth system, because I
realise after a few days that an update has broken something important.
Since I don't backup the actual recordings (for obvious space reasons),
just the rest of the system, it's possible for recording files to exist
which aren't in the database. My current solution is to include the
output of 'ls -lR' in the backup, so I can manually compare and cleanup,
but an easier way would be nice.
