[Bacula-users] mulit-drive changer, simultaneous jobs

[Anthony D. <ADodson@Lumenos.com>]

Hello all,

I have a 4 drive autochanger.  I am trying to set up bacula to run
simultaneous backup jobs from the local machine, to use several tape drives
at once.  I'm not backup up several machines, just one machine to it's tape
drive, multiple jobs with different file sets, volume pools, etc.

I have set Maximum Concurrent Jobs to 4 in the bacula-dir.conf, and have
defined the Drive Index = X for each device in bacula-sd.conf, and I can run
jobs manually and use any drive, but I can't get more than one job to run at
once.  "status dir" from the console reveals the second job, "waiting for
max Job jobs".

I know bacula's documentation speaks of only limited support for multi-drive
devices, using "Drive Index"... but if you can use more than one drive,
can't you use them at the same time (is it just redundant if you can't use
them simultaneously)?  I'm sure I'm missing something.

Do I need multiple file daemons running on the box (can one specify "Maximum
Concurrent Jobs" in the bacula-fd.conf?), and do I need multiple storage
daemons running on the box (is this logically possible), or am I totally
missing the boat.

Sorry if this is something simple that I've missed.  I've been through the
documentation a lot, but don't see anything relevant.

Thanks,

Anthony Dodson
