I am with them on this. I really do not like to see all backups on a
single raid. 2 raids each having a copy is fine however.

I believe the vchanger actually simplifies things instead of making it
more complicated because then you have 1 device that you send your
jobs to and bacula finds the space to put your backup.

This will get you back to the problem of assigning storage devices to jobs.

To write to multiple drives you need either multiple storage devices
and having to specify for each job what storage device to use. If the
drive fills it will not continue on any other drive. It would need to
recycle volumes on the same drive.

An alternative would be to externally manage the drive switching. This
can be done several ways. I mentioned several alternatives in my
previous post. Although I believe most of the ways are more
complicated than using a vchanger in the first place.
