I run into a similar problem and here's what I did.
1) Make sure your autochanger entry has all the drives list in the Device line.
Device = Drive-1, Drive-2, ...
2) In the Storage entry in bacula-dir.conf. Make sure you have a Maximum
Concurrent Jobs entry, 20 seems like a good number.
Storage {
Name = Autotape
Device = AutoChanger
Autochanger = yes
Maximum Concurrent Jobs = 20
...
}
3) If you have the disk space I would also recommend data spooling. It really
does make a difference in backup speed.
