A volume, although is a tape or dvd it is not the same as a hard drive
or mount. Bacula stores disk volumes as files. So on a hard drive you
can have 1 or more bacula volumes.

The file name of the volume is the same as the label. And the user can
label their volumes either manually or automatically using a pattern.

See:

You do not want multiple partitions.

Yes.

You can do this if you want.

You do not need multiple volumes per disk if the disk gets removed and
a new one gets installed when the harddisk fills.
