You can do that, but if you are using the very latest code, it is not
necessary. Bacula now knows how to spread jobs to separate drives.
However, if you want all jobs of name X to go to a particular Volume, and jobs
of name Y to go to a different Volume (and always the same one until it is
full) then having separate pools will permit you to do that.

Re: [Bacula-users] autochanger question
my version:
Version: 1.38.0 (28 October 2005)
Can you show a sample configuration setup of how I would spread jobs
over different drives (if it's possible in the version I'm using)?
thanks,

Yes, it is easy. However, 1.38.0 won't work. You will need the beta version
1.38.3, and preferably the one that I will release tomorrow morning -- 1.38.3
(19 December 2005). It also has load balancing -- thanks to David Boyes, who
made me think about it a bit :-)
Since it is late and my cats are demanding their midnight milk, I'll answer
your question tomorrow when I update the manual on precisely this subject ...

First, you need to download Bacula 1.38.3 (19 December 2005), then simply add
Prefer Mounted Volumes = no
to your Job resources in the Director, and run four or five jobs, and assuming
you have an Autochanger definition in your Storage daemon with four drives
configured, you should see your jobs select the four drives.
Here is what I have added to the manual. If this explanation is not
sufficient, please let me know:
If the Prefer Mounted Volumes directive is set to yes (default
yes), the Storage daemon is requested to select either an Autochanger or
a drive with a valid Volume already mounted in preference to a drive
that is not ready. If no drive with a suitable Volume is available, it
will select the first available drive.
If the directive is set to no, the Storage daemon will prefer
finding an unused drive, otherwise, each job started will append to the
same Volume (assuming the Pool is the same for all jobs). Setting
Prefer Mounted Volumes to no can be useful for those sites particularly
with multiple drive autochangers that prefer to maximumize backup
throughput at the expense of using additional drives and Volumes. As an
optimization, when using multiple drives, you will probably want to
start each of your jobs one after another with approximately 5 second
intervals. This will help ensure that each night, the same drive
(Volume) is selected for the same job, otherwise, when you do a restore,
you may find the files spread over many more Volumes than necessary.

Setting Excellent! This is exactly the scenario I'm in - an autochanger with two drives, only one of which is currently in use. Two questions about this feature, though: 1) I'm assuming that once a given volume is picked for a job, all data from that job will go to that volume (assuming the volume doesn't fill up, of course). Ie, if the job is large enough that it has to be despooled in several passes, will bacula ensure that it doesn't get split up unecessarily? 2) I'd like to start setting up different pools and policies for full vs incremental/differentials, so that older full backups can easily be transfered to offsite storage. To facilitate this, I'd like to be able to have all of a given run of full backups end up on a single tape set.

I don't think so, but your question is not very clear, so I'm not sure. The
only reservation I have is what is mentioned at the end of my text about jobs
run on different days.
