I don't believe so, but can check with OSL and what they have to offer.
This was part of the decision to go with a RAID 6 on the machine that
will have the backupVM (2 disks can die without data loss) and the
proposal to rsync/backup this virtual machine to a Telescience blade at
least weekly. Do we really need tape backup if we have good redundancy?

That's good to see someone already has some experience with one of these
tools. Do you have any particular hints, tips, gotchas etc - I notice
that bacula uses a database backend to track what it's done, do you have
a recommendation for which db to use?
