I'm used to fixed volume sizes from the tape drives, I feel

preallocate the number of volumes needed. Maybe there is no need, if
the volumes are created automagically. Most of the RAID array will be
used by Bacula, just leaving a couple of percent as free space. When
using mhvtl, I started a script with the tape size and number of tapes
I wanted, and the corresponding tape directories and volumes were
created on the fly.
Thanks Josip!
You are welcome.
I would like to point out that different requirements people may
have will dictate different approaches.
Regarding preallocation of the voluems, if there is a way to do it
I am not aware of it.
However, if you define maximum volume size and the maximum number
of volumes in the pool, you should be able to calculate the space
needed. Just leave some free space like 2x size of a volume and you
should be good. Later, when you use all the volumes you will see
if there is enough space to create yet another volume.
You can chose to label volumes by yourself or leave that to Bacula.
It's up to you.
If you intend to recycle your volumes automatically, make sure that
your retention periods are short enough to expire before all the
volumes are used. Otherwise Bacula will not be able to perform backup.
The alternative would be to force the recycle of the oldest volume
but this doesn't happen by default, this option must be explicitly
turned on.
Regards!
