Mmmh. Still I think it would be a good idea to first understand what's going on there. > I suppose one solution to the regression issue is to store the archive > in a filesystem or LVM volume that supports snapshots.

If we are only talking about a failed backup, then one level is the worst thing which can happen: last backup succeeded, this backup fails, discard the file-system snapshot, fix the underlying error and re try. > Like you, I'm no Python guy.

Ok, so: for myself my largest programming experience is in C and C++, more or less. Still: Python is widely used, it seems to be convenient for beginners, and: rdiff-backup is written in Python, no need to start something new. Seemingly, there is no real pressure to migrate to v3 ... Concerning the Python language personally I rather feel the lack of internal functions (private, protected etc.). However, so what. C++ is really really by far (maybe farest) imperfect and still carries tons of historical ballast.
