My last job, I was setting up rsync backups. What I did was create a user,
backup, then in /etc/sudoers, have !requiretty *only* for that user. The
user was also limited in what commands it could run (in that case, rsync
only).

Don't forget to log in as that user first, so that you don't get the "Oh,
This is a new IP, are you Sure you want to continue connecting?!?!"
