I usually don't like the idea of rsyncing bacula volumes and although
an example where such approach would be acceptable probably exist I don't
think this is the case here because of the requirements that were set in
the initial post.

Rsyncing of the volumes would take a lot of time unless one is willing
to use "--append-verify" rsync option.
One would also have to make sure that at the time of rsyncing volumes
those volumes are not being modified.

The problem with this approach is that original poster is looking for
a way to keep one or multiple removable media (e.g. large usb disk)
offline and offsite for some period of time (e.g. month) and then
periodically replace the media.
