Unison doesn't use rsync. As far as I know, Unison uses a rsync alike 
algorithm which is bidirectional, while rsync is only unidirectional.

Unison is still reading much data over my WLAN. Even in "fast check 
mode"! So comparing 20G data takes a loooong time (up to 10 minutes)
even is no new / changed files where found.

I've though about this, but I'm afraid that I forget to start a sync in 
the case the older archives have changed.

My first idea was a daemon which uses the inotify protocol of the kernel 
to get informations which files has changed. But this only works on local 
file systems. Changes on the server side would be invisible.
