rsync through ssh tunnel

I want to keep the content of some directories
on different Linux servers synchronal. I have on
every Linux server an account for connecting to
via ssh. This account has no root permissions.
But some directories require root priviledges.
I wand to use rsyncd as a deamon on the target

My Idea was to build a ssh tunnel first and then
using rsync via this tunnel. 

ssh -S -l user -L2020:localhost:873 host

When I use rsync ...

rsync rsync://localhost:2020/share

.. everything works as expected. But when I want
to use rsync for the real work ...

+ rsync --rsh=/usr/local/bin/ssh --recursive \
        --hard-links --perms --times --links \
        --safe-links --one-file-system --relative \
        --backup --backup-dir=/home/adv/rsync_backup \
       '--suffix="-11.06.04"' --compress --timeout=180 \
        --dry-run --verbose --stats \
        /sourcedir rsync://

FATAL: Connecting to rsync failed: No address associated to the name
rsync: connection unexpectedly closed (0 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(150)

.. I got this error message. When rsync wants to transfer 
data, will it use the ssh tunnel or will it use ssh as the
user executing the script (ex. root) ? Will the data be
trandferred between ssh and sshd or rsync and rsyncd ?

I am confused about that. Any hints are welcomed.
Thanks in advance
