I don't know if it's best - but I run backuppc inside a Xen VM
productively on a device that is forwarded via nbd (network block
device). It's quasi independent from the actual underlying storage type
and can be accessed over the network, since you don't necessarily have
to plug the USB disk into the VM's host machine.

Performance is of course not really great but surprisingly good. I
evaluated (very shortly) against mounting via NFS, and NFS just sucks
with backuppc.
