Hi
Thanks for your resonse, I am curious, what kinda script do you use to
delete purged volumes?? Do u run it in a bacula job or outside of bacula
a cron/Scheduler job??

I've never properly understood the scratch pool concept and i never
use it. I use disc volumes so there seems no reason to return an
expired volume to a scratch pool. I let Bacula expire and truncate
them and create new volumes as needed. Every so often i use a script
to delete the purged volumes from disc. Maybe it's different for tapes.

That is absolutely the way to do it. Each volume will be marked Used
when its Use Duration runs out. If there is no appendable volume
(all
are Used) when a job starts, Bacula will create a new one. The Used
volumes will remain present for restores until you clean them up.
The
typical approach is to use Retention settings to control how long the
backups are kept active, then move the volumes into the Scratch pool
when they are purged or all jobs on them have been pruned. From there
you can either delete them, or truncate and Recycle them.
