Default [Q] rsync backup without SSH?


I have a NAS that's running an rsync-service, so I can rsync stuff to it. It is not however accepting ssh-connections. I think it would be great if I could back up my pictures automatically to my NAS. And I can find a lot of apps that claims they can rsync. But every single one of them seem to use rsync over ssh.

Does anyone know of an app that lets me just use rsync without ssh?
