This seems like a fantastic tool, and I would love to try this out. And, it's free!
My personal obstacle in using a tool like bup is the back-up space. I could definitely use this for on-site/external storage devices, but I also like to keep online/cloud copies. I currently use CrashPlan for that which affords me unlimited space. If CrashPlan would let me use their cloud with bup, wow, I would switch in a heartbeat. Perhaps cloud backup tools could learn some tricks from bup.
Aware of Tarsnap and looks very attractive. I'd rather pay a flat-rate out because I store a lot of video (Musician) and other large files. I have about 750GB pre-deduplication stored. That's a lot more $ when I go to Tarsnap.
