[BackupPC-users] backing up over WAN

Hi,

we need to setup a "reasonable" backup solution for one of our
customers, consisting of a HQ office and two branches. The most
important requirement is off-site backup. Backup volume will be
approximately 50 GB per office for a full backup, meaning 150GB in total.

So far, we have used backuppc for almost any backup solution, but this
time I am not 100% sure because of the "WAN" side of life.

What I am wondering is if it was possible to retrieve files from the
clients more intelligently:

If I understand BackupPC's pooling concept correctly, pooling takes
place after the file has been transferred to the server and is compared
to other files in the pool.

Yet what I have in mind would be "don't transfer a file if we already
have it in the pool", thus drastically reducing the amount of data
transferred over the net.

IIRC, the rsync protocol per se should just allow that, but I am unsure
if BackupPC utilizes it at that level.

So is this "transfer minimization" doable with BackupPC?

Thanks in advance :-)
