rsync - Sep 2004 - how to rsync over ssh, but login is not permit

Hi, I want to backup my system via rsync over ssh, but login is *not*
permited! 

According to the sshd_config man page, I need to set PermitRootLogin to 
forced-commands-only.  

In order to run follow command, how to set command option in authorized_keys? 

# rsync -avz server:/etc /backup

Best Regards!
