I'm answering not exactly to your question, but you might be interested
in this :
If you consider using ZFS as BackupPC's filesystem, there is the awesome
combo :
zfs snapshot # makes a snapshot of you filesystem, for instance on a
daily bases
zfs send snapshot | ssh backback "zfs receive"
and your filesystem will be exported on host backback AND you will be
able to travel in time by munting the daily snapshots.
