Re: [Bacula-users] backup rotation, recycling and getting bacula to reuse a tape
2010-02-25 01:25:58
I think I know the problem but I couldn't test it because my patients ended
with bacula and I erased all tapes and deleted the volumes for relabeling. I
discovered I have to update a volume to remove it from the pool when it is
removed from the library. It looks like I cannot simply update slots before
running the job. Wow! This is getting complicated.
