Hello! > My central rdiff-backup server has version 1.9.1b0. Now I need to backup a > Debian system and this system and even the latest ( > https://packages.debian.org/buster/rdiff-backup ) uses 1.2.8-7.
Versions 1.4.x and 1.9.x are pre-releases of version 2.0.0. This was not that well communicated. In future the development releases will be more clear about what they are development versions for, e.g. 2.0.1~pre1 or 2.1.0~beta2 etc. Exact suffix I don't think has been decided yet (it is not at least documented in https://github.com/rdiff-backup/rdiff-backup/blob/master/docs/DEVELOP.md#versioning yet) but the prefix will be marking what it is a dev version for. So, if anybody is running 1.4.x or 1.9.x somewhere, please uninstall it. Don't run development releases in production, that is just asking for trouble. Please use the official 2.0.0 release instead. I also noticed that our README has an error, it recommended people to install development versions without proper warnings. This is now addressed in the PR at https://github.com/rdiff-backup/rdiff-backup/pull/325/files - Otto
