Hmm. Should work. BUT using more than one Media Type (and thus,
implicitly, more than one storage device) makes restoring rather
difficult. But you _have_ to use one job definition per... yes, per job :-)
Not one job for full and one job for diff, both using the same fileset.
Maybe this is were I´ve made my mistake to begin with... I read
through the chapter about "Basic Volume Management" -->
"Considerations for multiple clients" for the fifth time :-) and found
that the recommendations were that you should also specify different
Media Types to be shure that the volumes are saved on the right
Storage Device.
Yes, that might help.
The problems I´m having are not that Bacula does´nt create the backups
but that it also creates 0 byte Volumes on the wrong Storage Devices
and are reporting errors about this in the mail reports... Maybe the
problem disappears if I also specify different Media Types as File1,
File2 instead of only one Media Type? I´ll try that tomorrow night and
see what happens.
You'll have to try, I never really used automatic labeling or backup to
files.
...
I´ve read quite a lot of the Bacula documentation but I´m not sure if
I have understood it and implemented it all correctly ;-)
Well, I guess most bacula users needed some time to get it working as
wanted, and the more complex your needs are the more time you've got to
spend on it. Obviously. Well, bacula is simply very flexible, and that
has a price.
I´ve attached my bacula-dir and bacula-sd config files with this mail.
If you have the time I would be very happy if you could take a look at
them to see if I have misunderstood the hole Bacula concept... But I
fully understand if you don´t have time to look at them.
Well, I looked :-)
First thing I find in bacula-dir.conf is that you still seem to have job
definitions in it where you separate full and incremental jobs into
separate job definitions. That's just what won't work.
You need one job definition, like
Job {
Name = "nitrogen"
Client = nitrogen-fd
JobDefs = "FullJob"
Storage = "Nitrogen-Full"
FileSet = "Nitrogen FileSet"
Write Bootstrap = "/usr/local/bacula/var/bacula/working/nitrogen.bsr"
}
And in the schedule you can do things like the following:
Change
Schedule {
Name = "Full"
Run = Full 1st sun at 01:05
Run = Differential 2nd-5th sun at 1:05
}
Schedule {
Name = "Incremental"
Run = Incremental mon-sat at 1:05
}
to something like
Schedule {
Name = "Full"
Run = Level=Full storage=Full 1st sun at 01:05
Run = Level=Differential storage=Diff 2nd-5th sun at 1:05
Run = Level=Incremental storage=Incr mon-sat at 1:05
}
Like this:
Define job with client, fileset, name, schedule, options. You can use
the directives to setup different pools per backup level.
You create one schedule:
Setup name and multiple run lines, for example
run= storage=S-Full level=Full pool=Full fri at 23:00
run= storage=S-Diff level=Differential pool=Diff mon-thu at 23:00
When I first tried to do my concurrent multi client, multi storage
backups I did try this... But with three Pools and two Storage Devices
but then I could not get the concurrent jobs working, Bacula was just
waiting for the first job to finish before it continued with the next
job.
Can't tell you why exactly, but it is important to make sure that no two
jobs try to access one storage device and different volumes. Even though
with file storage that could work, bacula doesn't like that because it
also has to know how to handle tapes.
that's all.
And yes, you can run jobs concurrently, although using spooling seems to
be avery good idea then. I do that and it works ok.
I thought spooling was effective only when you are doing backups to
tape and not when you are backing up to disk?
Right. It's only that I'm used to think in terms of tapes... And
probably, similar to tape organization, restores can be faster using
spooling because jobs will not be stored interleaved in the volume files.
...
No, the only reason for me wanting the full backups on a different
partition is because I´m going to move them off site and I thought it
would be easier to move them by just having them on one mounted disk
instead of mixed full and incr backups all over the place :-)
Quite a good reason, I think.

Unfortunately, Bacula does not support what you are trying to do. The guys on
this list will help you do what you want using Pools -- one Job and one
Storage device.
You could override the jobs storage device setting in the schedule.
For example, define the job with the storage for full backup, use full
pool and incremental pool settings, and in the schedule for the
incremental you add storage=xxx
Something like this works here with tapes and different tape drives.
BUT there are some more-or-less serious disadvantages:
- automatic job upgrading doesn't work as it should, and
- restore can be a pain.
You can find more details in the list archive. Or, best solution, try it
for yourself :-) as that's the only way to definitely find out if the
additional trouble is ok for you.
In your place, I'd use your system's volume management to simply join
the available partitions. Of course, that increases the risk of errors,
but that's what you get for doing backups to tape ;-)

Hi Kern,
Thanks for your quick answer.
Maybe I was somewhat unclear in my problem description :-)
I´ve defined two jobs and two storage devices for each client, one
job/storage device for full and diff backups and one job/storage
device for incremental backups...
The reason why I did this is because I want the volumes containing the
full and diff backups to be stored on a different partition on my disk
storage.
I´ve specified "Maximum Concurrent Jobs = 4" in bacula-dir.conf and
bacula-sd.conf and when all the client starts at the same time Bacula
seems to get confused about which volume to create on each storage
device.

Hi,
I´m using Bacula to backup all my clients to a large disk storage...
In my bacula-dir.conf I´ve specified so that a separate volume should
be created for each of my clients full, diff and incr backups. These
volumes should also be stored on different disks/partitions based on
if they are full or incr backups.
This works somewhat fine :-) But the problem is that even thou I´ve
specified different storage devices for each client in their job
resources the director tries to create a wrongly named volume (a
volume for another client) on the specified storage device.
Here is a bit of a mail report from Bacula that I´ve cut and pasted:
---snip---
05-Jun 14:50 nitrogen-dir: Start Backup JobId 26,
Job=platinum-full.2005-06-05_14.50.01

05-Jun 14:50 nitrogen-sd: Wrote label to prelabeled Volume
"thorium-full.2005-06-05_14.50.02" on device "/vol/1/platinum-full"
---snip---
Does anyone have a clue on why this is happening?
Maybe I´ve done something wrong when configuring the bacula-dir and sd
config files ? :-)
I can mail the content of the config files if this will help...
