So the question has come up about storing our backups off-site.

We're using disk backups, with two USB disks.  Each disk is a
Storage, and each Storage has a single Pool, and each Pool has max
200 4GB volumes.  Part of my configuration is below.

What I'd like to do is buy a second matching set of USB disks,
take the existing disks off, mount the new disks in the same place,
and just have Bacula pick up where it left off, seeing no volumes
and creating them as it needs to.

(We do full backups once a month anyway, and I would probably do it that
morning.)

Then in a month, I will do it again, take the disks off, put the
old disks back in, and Bacula will just notice all of its old volumes
are back.

Is this a workable solution?
