Parent needs voting up. With EncFS, you can even use the reverse function, in case you like your local files unencrypted for some reason, to get an encrypted "view" of the files and sync that. You can mount a remote Windows machine's drive, for instance, get an encrypted view of said drive and sync that to the cloud.
Also, check out Jottacloud if you have a Windows machine available. I don't think their "unlimited storage" deal can be beaten.
