Hi Arno,

Thanks for the response.

I don't think so, I understood how things worked where I was looking, 
but wasn't looking in the right place. After reading your response I 
found the explanation in the "Basic Volume Management" section. Maybe a 
link between the two sections would be useful.

Okay, that's what I thought. Thanks for confirming.

Ah-ha! I think I understand now, and ironically while looking for the 
"Tips and Suggestions" section to respond to your question above, I 
found the "Basic Volume Management" section in which it pretty plainly 
says I will "need multiple Device resources in your bacula-sd.conf file, 
and thus multiple Storage resources in your bacula-dir.conf."

I write one job per volume, and currently all volumes are in one place, 
e.g. "/var/bacula/monthly-0003". After reading some more, I think I 
should be able to make four more identical (except for Name) Device and 
Storage resources that all point to the same directory and it will be 
able to write up to five jobs at once.

I was planning on splitting my volumes up, however, so each client had 
their own directory and volumes, e.g. "/var/bacula/foo.domain.com/0001" 
and "/var/bacula/bar.domain.com/0001", which I think means I would need 
additional Device and Storage defnintions each with their own Media 
Types, like "Media Type = File-foo.domain.com". I'll have to think about 
if I still want to do that and how to organize it...maybe just different 
pools.

Is there a way to prevent Bacula from killing the job after just a few 
seconds of waiting for the volume? Last night I had a large backup 
running and eight incremental jobs failed because they couldn't mount a 
volume...I can see this happening in the future if there is a large 
backup or two, even if I have a number of Devices, so maybe that's not 
the best course of action. Is there some sort of timeout option? Would 
data spooling take care of this?

Thanks again,
Josh
