It's perfectly possible. First, look at your various retention times.
If all the jobs on a volume have been purged, that volume will become
purged. If the volume retention time is reached, the volume will become
purged, and any jobs associated with it will be purged as well. Easy.
When Bacula needs a volume, it does 3 things (in order):
1) Looks for any unused volumes
2) If #1 fails, finds the oldest purged volume and recycles it for reuse
3) if #1 and #2 fails, requests operator intervention.
Note that this is an oversimplification. This process can change based
on your configuration. Refer to the docs for the full process.

That's a potential improvement.

Without knowing what your requirements are, it's hard to say for sure,
but I would suspect that configuration is over-simplified and part of the
reason you're having trouble.
Note that RecycleCurrentVolume respects retention periods. If your job
and file retention periods are too long, Bacula won't recycle the volume.

That's not true. The trick is to bscan the tape in, then manually reset
the retention time on the volume so everything isn't purged the next time
you do anything. You can then work with the volume as much as needed and
manually purge it when you're finished.
