Duplicity is a simple tool for signed/encrypted (PGP) differential backups using a variety of protocols including: ssh/scp, local file access, rsync, ftp, HSI, WebDAV, Tahoe-LAFS, and Amazon S3. I'm assuming that rackspace storage supports at least one of these?

There is a very easy to use command line interace, and also a GUI (which I have not tried).

Thanks, I love duplicity from a technical standpoint, but for some reason, I'd like to have a native OSX UI and the ability to access my data from my iOS device while on the go.
