When I had to pick a backup system, I considered Bup until I saw that there were no way to prune old backup ( https://github.com/bup/bup/blob/master/README.md#things-that-are-stupid-for-now-but-which-well-fix-later https://github.com/bup/bup/blob/master/README.md#things-that... ). This is really a stopblocker for me. Obnam ( http://obnam.org http://obnam.org ) is a similar tool but support forgetting old generations. However, it still suffers for youth problems and tends to corrupt backup repository when pruning old data on a remote server. I'm really looking forward for a mature and feature full backup system based on git principes. Bup or obnam might be one of those.

I wrote ddar before I knew about bup. It works in a similar way, but uses sqlite and flat files for chunk storage, so removing old archives isn't a problem. I'm not aware of any corruption issues in ddar; I rely on sqlite for integrity. I modeled ddar after Tarsnap.

    I'm aware, thanks. https://github.com/basak/ddar/wiki https://github.com/basak/ddar/wiki contains the content, thanks to a kind contributor. I should probably deprecate the old URL and remove references to it.

      Perhaps you could have it redirect to the wiki?

  ddar sounds like it could be really useful. However, it looks like the last functional change to code base on GitHub was a year and a half ago. What do you think the future of the project is? For something like backups, I wouldn't want to invest into a tool that has no prospect of support.

Obnam I liked using, because I love the authors attention to testing and details. But I found it started taking longer and longer and longer to run a backup - to the point that it was crazy. I switched to atic instead, which also started taking longer to run backups as more things changed, and longer still to check the archives, but it is still faster than obnam by a significant margin: https://attic-backup.org/ https://attic-backup.org/
