Correct. > I see - so you wouldn't compress the file, you'd compress the tunnel... > Makes sense... > Would it then still get compressed when stored at the other end? Yes, if you set the backuppc server to do so. Compression of the tunnel just sends the bits across the line more efficiently, but at the other end they are decompressed to be the same bits when received. Then the backuppc server can optionally store them in a compressed pool. If you don't compress them, my understanding is that they will be stored in a much more easy to access format on the filesystem, which is handy if the backup server goes down for some reason, though I've never tried it since I always use compression... > How well would that work for something like LVM snapshotting? > I'm thinking of migrating my windows servers to Xen Virtual Machines on LVM > drives > If I take a snapshot of the drive and then mount it somewhere, could I get > BackupPC to copy only the changed data as rsynch files?

It does intelligent pooling as far as I understand, meaning it will store the big file once, and then store the next versions as differences to the original. Am I correct on this list readers?
