I have a hunch that what he is really getting at is two separate
features. I could be way off base, my mind reading machine is currently
in the shop ;-)
He would like a volume marked used not at the beginning of a backup job,
but only after the backup job has successfully completed. That way, if
the backup failed, the same tape could be reused.
And he also would like a way to specify for bacula to use a new tape for
each job (like the Max Volume Jobs directive already, but that uses up a
tape even when the job later fails).
Whether these are good features to have is a different story. In my
mind, even a failed backup job has some value as long as at least one
file did get backed up (backup jobs that fail without ever backing up a
file obviously are useless - maybe that's the scenario he is thinking of).
