This should give you an idea about the worst-case date transfer (it
ignores the ssh compression advantage):

rdiff-backup --remote-schema 'pv -b -N Upload | ssh %s '\''rdiff-backup
--server'\'' | pv -b -N Download' SOURCE DEST


(uses pv - "Pipe Viewer", Ubuntu package for example:
http://packages.ubuntu.com/jaunty/pv )
