I am confused how it does not solve the problem. I am talking about
using rsync to mirror the volume files that bacula uses to store all
of your backups. If you limit the size of these to a few GB, rsync
will only be sending the volumes that have changed but you will still
have a complete second copy of the bacula volumes offsite.
