Machine B is the machine to back up. On machine A create your public/private keys via ssh-keygen Copy the generated public key to Machine B (append the key to the appropriate "authorized_keys2" file) On machine A run: eval `ssh-agent` (make sure these are both back-tics `` ) On machine A run: ssh-add (You'll have to re-enter the keyphrase) On machine A you can now run: ssh <machine_B_IP> (and you should not be asked for a password.) For batch use change the line for BatchMode in /etc/ssh/ssh_config to: BatchMode yes You should now be able to run a script containing ssh commands: (note that the ssh-agent should be only viable for the current login session but that doesn't pose a problem for my use. I have run across a site that where someone created a utility to allow the ssh-agent to be accessible from a cron task or a shell other than the login shell but can't remember it right now.)
