you need to put your public key (usually stored in ~/.ssh/id_rsa.pub) into
the authorized_keys file on the remote machine (usually stored in ~/.ssh/ of
the home directory for the remote user), this will use public key 
authentication and no longer prompt for a password

along these same lines you can use rsync with ssh to do backups (although they
won't be compressed)


hope this helps
