Looking at the README under "Stuff that is stupid":

Thanks for the rdiff-backup shout-out. I'm looking for a nice way to do system backups to my NAS of large VM images without having to install Crashplan. Bup and rdiff-backup both look pretty good.

Obnam is also great: http://liw.fi/obnam/

This does deduplication, but can also encrypt the deduplicated blocks and store them on (say) S3.

Obnam can also push/pull backups over SSH/SFTP. Seconded.
