Hello,
Bacula was not designed to handle the case you are describing where
you have multiple clients that are offline. This was not really a
design decision, but rather a design limitation because when the
code was implemented there was no restart functionality.
A possible way to fix the problem would be to use Max Full Interval
and Max Diff Interval ...
Best regards,
Kern

Hello,
I
concur with David. When these jobs are scheduled,
Bacula will attempt to acauire the needed Storage
resources. When the resources are busy the job waits,
and after a certain time, Bacula will inform you that
the resources are not available.
These
messages generally occur when you over commit the SD
resources. If you are using disk, increasing the
maximum simultaneous jobs in the Device resource and
restarting the SD will generally solve the problem, but
you might also have to assign more Storage devices
depending on what you are doing.
I think this is a somewhat unfortunate design decision,
to be honest. I back up a fairly large number of
workstations, and on any given night a certain number of
them will be off or otherwise unavailable. I have these jobs
set to reschedule on failure so that they run when the
workstation eventually gets switched on.
The problem is, with the behavior you mention, I can't
accurately control how many simultaneous *running* jobs are
using storage. If I set the max to the number of jobs that I
actually want to be able to use storage simultaneously, I
end up with some jobs that could otherwise run waiting for
resources because those resources are committed to a job
that's retrying a workstation that may or may not appear. If
I compensate by setting the max higher, I risk
overcommitting my storage bandwidth on nights when all the
workstations *are* available.
