Good point that I should have mentioned earlier. Remember that if
_anything_ in the VM changes (such as a log entry), then the host system
will see the virtual disk as changed and back the whole thing up. You
can end up backing up 20 GiB per day just to accommodate a few KiB
change in the VM.
A lot depends on how you do your backups, but I set things so that if
the VM is running at backup time _it_ backs up its disks, not the host.
Indeed! Having the host include the VM image files in its backup
is equivalent to using "dd" to back up entire disk images and
having that as your sole backup mechanism.
