Yeah the method is rsyncd. I understand what you mean now, makes much more sense! thanks.

Is the XferMethod rsync?  If so, this behavior is expected,
since rsync just sends file deltas, rather than entire files,
across the network.  BackupPC reports the total size of the
files that were sent, even if the delta was much smaller.
