Hi,
You should look to this option :
*Prefer Mounted Volumes = <yes|no>*
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.
