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.
