rsync using ssh as transport is one nice option if you have hte
benefit of an rsync server on the far end.

Example:
client$ rsync -avz -e ssh /home/me/ remote.colohost.blah:/home/me123/mybackup

Or you can do the usual scp thing though it's not as bandwidth
friendly.

In ssh parlance, you wish to use public key authentication with a
private key that has no pass phrase.
