How does this compare to Duplicity?

[scott_karana]

It uses git-style addressable blob storage, so you don't have to worry about deltas, because there aren't any.

It's also got more efficient deduplication, because it doesn't use rsync's naïve algorithm.

The downsides: it requires the agent to be remotely installed (a la rsync: no "dumb" backends), and supports less storage backends to boot.

YMMV :-)
