Or he could use SSH2 keys and an authorized_keys2 file, with ssh set to
allow root on forced-command-only. This would prevent root logins, but
allow a single box (or boxes) to rsync in and have read-only access to a
specific share. Or you could create a passwordless uid 0 user
specifically for this purpose. If you were really paranoid, the
forced-command could be a script to check for abnormal behaviors and
bail out if something is fishy. There's multiple layers of
authentication (the key itself, the from-host of ssh, and the allowed
host in rsync), and exactly what is backed up can be pretty locked down
and chrooted to prevent intentional or unintentional misuse.
