Your solution is working well and it is similar to my current configuration
(all laptop are syncing their D drive to the home dir of the user that owns
the laptop on a Filer:user work saved).
The problem is that due to multiple instances of the same file on the server,
we run out of space (80 laptops 60GB each even if not full is pretty much).
So we bought a DELL SCSI Bay that has 1.6TB of storage space for backuppc
thinking that we would reconver our Filer in project storage only.
Currently, our vital data from our servers is stored using bacula with offsite
clones and lpatop are backed up with BackupPC while still being synced to our
Filer (until I find a solution to offsite backup my BackupPC server using my
available resources).
Thus in case of hard drive crash, I can quickly recover the hard drive and in
case of DRP, I have the Offsite Tapes of the Filer.
My dream would be to have my servers backed-up using BackupPC with a remote
BackupPC as failover in case of DRP. That would greatly reduce tape usage as
I would avoid daily tape incrementals, I would reduce tape usage beacause of
single instance storage and I wouldn't need offsite storage anymore (full
tape bacups would only be used for long term archiving).

Anyway, your solution is interresting and will surely fits some readers needs.
BTW, maybe it could be interresting to have a backup strategy page in the FAQ
of BackupPC with pro and cons for each?
