neither... you must understand that duplicity uses librsync internally to find 
out which parts of a file really changed. These parts are transported via 
several backends to the backup storage.

One of the backends is a rsync backend. It uses a local rsync binary to 
communicate with a remote rsyncd or a remote rsync instance started via remote 
shell (e.g. ssh). This of course uses the rsync algorithm as well but because 
every volume is essentially new this brings no advantage in speed or bandwidth.
