True; but that is biting a bit: I create a large file, it gets
backed up, and the next day I send it to my parents behind a slow
(asymmetric) DSL link. The subsequent backup of their machine will
then require the full file transferred back upstream.

As I wrote in my previous mail, if rsync provides a way to request
the full file checksum from the peer, then this could be a nice
optimisation to BackupPC.
