In addition to what Dan wrote, here's a snippet I usually just cut-n-paste to my sales reps and customers when they ask a 
similar question:
----8<----
Bacula does not need any special drivers to operate tape libraries or drives.

If the tape drive is presented by the kernel as a '/dev/st<x>' node, and can be controlled with the standard Linux 'mt' 
utility, and the Tape Library is presented by the kernel as a '/dev/sg<x>' node, and can be managed by the Linux 'mtx' 
utility, there should be no problems at all.

Please see the Storage Resource section of the main manual to see how to configure the Storage Daemon's 'Autochanger' and 
'Device' resources here:

https://docs.baculasystems.com/BETechnicalReference/StorageDaemon/StorageDaemonResourceTypes/AutochangerResource/index.html#autochanger-resource
----8<----

That has held true for me in the 20+ years I have been working with Bacula Community, and 10+ years working for Bacula 
Systems. :)


Best regards,
Bill
