Creating a single volume like this would be a very bad idea. It would
grow either until it hit whatever volume size limit you set, or until it
filled up the available disk space, at which point you would be unable
to run any new backup jobs until either all of the backups passed their
retention date or you manually purged the volume.
For what it's worth, I find the best strategy - for me and my needs, of
course - is to allocate new date-labelled volumes with no size limit but
a 23h limited volume use duration, each volume holding a single day's
jobs. Thus every job in each volume expires at once, at which time
Bacula automatically purges them and moves them into my scratch pool,
from where an admin job deletes the purged volumes once a week.
