That's the best way.

It's not "without authentication" - you're still authenticating, you're
just using a different means. There's two parts to rsa/dsa authentication
with ssh; first there's the key, then there's the passphrase.
If a cracker gets your key, that's tough, but they'll need the passphrase to
authenticate. If you make a key without a passphrase (generally what you'd
do for scripted rsyncs, etc) then they *only need the key*. So, you should
keep the data available with passphrase-less keys either read-only or backed
up, depending on its importance, etc.
