Backups!

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

http://duplicity.nongnu.org/

  • 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?

The downside for me would be the need to have significant spare space locally.

duplicity can use remote as well as local targets, including support for Amazon S3. It's possible I'm misunderstanding you though?

From the FAQ:

"Duplicity may require lots of temp space sometimes, depending on the size of the volumes created..."

I'm guessing that you could arrange to have that remotely, albeit at a cost in time and possibly money.

But I know how every OS I have ever run behaves when its file systems approach or reach fullness. (Ubuntu has improved greatly, for example.) Having a reasonable speed net connection combined with no quota doesn't help. It is, in part, an addiction: there is so much good stuff out there, and I wants it my precious...

This has been one of the reasons I like what I have for Windows - it uses a delightfully small amount of local disk space.
