Thanks a lot, Arno. Your reply saved me a day of scanning through the
documentation! Things looked a bit confusing because apparently, the guy who
installed Bacula first tried version 1.38.x and then settled down on 1.36.1
for whatever reasons he had. That left a bit of a mess in config files.
BTW, is there a place to submit user tested Bacula-compatible hardware setups?
The one included with the documentation (well, both of them) look outdated
and unmaintained for years. It is rather short also, which IMHO is misleading
and can discourage potential Bacula users. It is my understanding that in
reality Bacula will happily work with almost any autochanger/tape drive
hardware except probably most exotic models.
Regards,
Ivan
