Regardless whether this loopback-file is on a local disk or via nfs/smb
mounted, this has the advantage that you can add encryption via luks to
the equation...
But why do you want to run backuppc on a server with the files on an
external nas? This has to many drawbacks:
a) If one of these two machines fails, there is no new backups and no
restore (at least during the outage).
b) If the server is also the one providing ip addresses via dhcp and
the nas needs an ip address, you get a nice loop on fresh starts like
after a power-outage: The nas won't be accessible as it doesn't have
an ip address and the server will not boot (and start backuppc and
dhcp-server) because the device isn't reachable for mounting.
We use an internal disk for backuppc and write weekly/daily
encrypted 'tapes' to the nas which gets mounted for that (either via
nfs or iscsi). When the nas isn't there, we don't write the tapes. We
could also make the scripts try a second nas when the first isn't
there. Which gives the advantage of movable tapes with modern (and
cheaper) disks.
Have fun,
