Backups!

[ciphergoth]

Further to my last post about backups, it looks like someone has written the backup tool that I wanted to exist:

• All cleverness is on the client - the server can be a dumb store like Amazon S3
• Backups are therefore initiated on the client - good for sometimes-on machines
• Backups can be encrypted and signed with GPG
• It supports incremental backups of large files, using rdiff "signature files"
• All in Python, appears quite new

Support for non-Linux systems seems to be pretty weak at the moment, but I don't see anything that would make it inherently hard except possibly the use of "tar" as a container.

Thoughts?
