Actually, I just did a test, using iptables to count bytes between
the two hosts, and then renamed a 33M file. backuppc, using rsync,
only transferred 370k. Hence I think that it actually does *not*
transfer the whole file.

(btw, I also think that what I wrote in
http://comments.gmane.org/gmane.comp.sysutils.backup.backuppc.general/24352
is wrong, but I shall follow up on this when I have verified my
findings).
