I suggested ssh keys without passphrases (while sternly warning of the
potential implications) in
http://www.barryodonovan.com/publications/lg/104/ and it includes
instructions.
Depending on your environment, passphrase-less ssh keys might be
applicable.
Some details I didn't go into in the article were to be sure to use a
specific key for only this purpose and use a restricted account on the
remote server (such as setting the shell to rbash - see man bash and look
for RESTRICTED SHELL).
You can invoke rsync over ssh and specify a specifc key with:
rsync -a -e "ssh -i /home/username/.ssh/id_rsa-serverbackup"
