I've used S3 and WebDAV. It does rsync like backups so that you're only sending differences across the wire, and if you are using encryption, it will encrypt all of that before it sends it over. Pretty slick. The newer version has the ability to flag stuff being sent to Amazon S3 as reduced redundancy storage, so you can pay the cheap price if so desired. In short, I like it. The only thing I don't like is that you still have to do regular full backups (rather than constant incrementals like you can do with straight rsync), so if you're being billed on bandwidth (like with Amazon), that can bite you.
