Ssh will keep a tunnel open as long as a tcp connection is open through
its tunnel. But since your timeout expires in the first run, it will
exit when the first rsync completes and closes the connection.

Ssh is pretty robust, but if you have keys set up for passwordless
connections you could wrap it in a shell loop that runs it again if it
exits.
