Hmm... the manual says I am right :-)
But I admit there are some other factors that can influence the
recycling algorithm - tapes in the autochanger are preferred, for
example, IIRC.
Also, I'd say that Kerns recent reports on recycling improvements
indicate that, until now, volumes were purged more aggressively than
strictly necessary. In my experience, once Bacula started purging
volumes, it purged all expired volumes, not only the one it would use
later. I skipped these details to not add to any existing confusion.
