100% sure

this below is the vnstat-output of my main backup-machine
every night there are synced 1.5 TB data with the rsync.sh
from my last post

with rsync you can even transmit iso-images of a linux
installation-DVD and update RC1 to RC2 without much traffic

oversimplyfied:
* on both sides a rsync-process is running
* both are making a checksum of the same data-area
* let's say 250 blocks
* only this cheksum is transmitted and decides transmit data itself
* attributes are also listed on both sides and compared

finally i did recursive chown/chgrp/chmod with find on a server with
around 700k files, with progress/verbose rsync is listing them all,
the changes are applied on the receiver but the amount of transmitted
data goes to zero - without measure it you see the speed over WAN

thats why rsync over ssh with --compress is my most loved tool
