Is it a bug that bacula cannot write to multiple drives for the jobs in the
same pool? Will there be a fix. Back in March 2014 Wolfgang Denk wrote "it can"
but how?

It's not a bug, but just the way it's designed.
"Prefer Mounted Volumes=no" it's a directive that could allow to write multiple
volumes within the same pool at the same time, however this is a little buggy
and not recommended at this time.

backup time. But bacula insists on using only the first drive. Backup jobs are
not sent to other suitable tape drives. Jobs are started at the same time and
queued. Jobs in the queue is waiting for the previous job to finish even if
there is a valid media (tape) for the pool and other drives are idle. I can
mount other drives manually. Is there any other setting I'm missing to make use
of multi-drives? Please advise.
Hey Mr. Suleyman: if you want Bacula to write in more than one drive
simultaneously, the most reliable option is submit the job into different pools
at the same given scheduled time.

Assunto: [Bacula-users] bacula can't make use of multi drives
Hi,
I am trying to make bacula use multi drives in a Fujitsu Tape Library with no
success. Recently I added 3 more drives to bacula configuration to reduce
backup time. But bacula insists on using only the first drive. Backup jobs are
not sent to other suitable tape drives. Jobs are started at the same time and
queued. Jobs in the queue is waiting for the previous job to finish even if
there is a valid media (tape) for the pool and other drives are idle. I can
mount other drives manually. Is there any other setting I'm missing to make use
of multi-drives? Please advise.
Regards,
Suleyman
