My laptop rsync's /home once an hour. It works very well, and uses ssh
public keys to authenticate.

The command looks like this:

rsync -avpogtL --numeric-ids --rsh="ssh -l root" \
- --rsync-path=/usr/freeware/bin/rsync \
- --exclude-from=/root/thinkpad_excludes.txt /home/ \
indigo2:/data/backups/thinkpad/

Replace the --rsync-path argument with the path to rsync on the server
(/usr/freeware/bin/rsync in this case). /root/thinkpad_excludes.txt
contains entries like:

*/.tmp
*/.temp
*/temp
*/noarchive
*/scratch
*/.??*/*/*/Cache
*/.gimp*/gimpswap*
*/.Trash/*

This avoids rsyncing pointless stuff, like huge undo files from Gimp.

Generate the public key on the laptop with 'ssh-keygen -t rsa' and
append the contents of the resulting .pub file to
~root/.ssh/authorized_keys. Make sure public key authentication is
enabled in sshd.conf.
