Subject: Re: [Bacula-users] Using tape autochanger
I think this:
>>Here is the storage related sections of -dir.conf in directory /etc/bacula:
Storage {
Name = LTO-2
Address = host.domain.com
SDPort = 9103
Password = host
Device = /dev/st0
Media Type = Ultrium2
}
Should be:
Storage {
Name = LTO-2
Address = host.domain.com
SDPort = 9103
Password = host
Device = Autochanger
Autochanger = yes
Media Type = Ultrium2
}

You were right. That was definitely the issue. I misunderstood the
documentation in regard to this. Thanks for catching it! My backups
are now working just fine, for the most part. I will submit other
emails as questions arise, so as not to hijack this thread and take it away
from the simple subject and solution.
Thanks a bunch!
