For those that want to run a similar service using their own systems, I found that Attic [1] is a great open source backup tool that works in a very similar way, including deduplication and compression.

I backup some VPS servers to my NAS at home using attic over an SSH tunnel. Incremental backups are quite small and it's easy to automate with a simple cron job.

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 :-)
