I wrote my own backup system, called Snebu (http://www.snebu.com http://www.snebu.com hosted on github at http://www.github.com/derekp7/snebu http://www.github.com/derekp7/snebu). It works a lot like rsnapshot, but uses an sqlite3 DB for metadata storage and also does streaming compression (and encryption filter module is also coming soon). Client side resources are light -- just requires a system with gnu tar and gnu find, along with a bash shell for running the client-side script.
