Interesting, thanks. I've been using rsnapshot for years, and am
basically satisfied with it, although the performance when run on my
T61 laptop (backing up to a (slow) USB external disk) is indeed painful
(I do have largeish Maildirs). [Interestingly, when run on my ARM
(Kirkland) NAS, pulling from the laptop over ethernet / wifi,
performance seems much better ...]
One thing I really like about rsnapshot is how the backups are all
stored just as the files themselves, without any special formats, and
can therefore be inspected / restored from using just the ordinary
filesystem tools.
A number of years ago I looked at rdiff-backup, but dropped it due to
suspicions of the code quality: the project seemed to be dead, and even
significant bugs were being ignored:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=623336
https://lists.debian.org/debian-user/2012/10/msg00182.html
I see that you, too, have a report that's been ignored for more than 5
years ;)
Am I being unreasonable? You are certainly more of an expert than I - I
suppose you find that it is quality software, and better than
rsnapshot, despite basically being dead?
