I haven't pushed it very hard. I'm only using it for personal stuff. That said, it's pretty good at DWIM for a command-line tool. It works as advertised and doesn't require any fiddling once you have it set up. cons: command line syntax is verbose. Enough so that there's a wrapper for it (http://duply.net/ http://duply.net/) which I also recommend. Access to backups isn't as straightforward as with forest-of-hardlinks approaches. I'd be interested to hear how it holds up to production use.
