I'm pretty sure this has something to do with having files with special characters in the name (á, ç, ã, etc). I'm a maintainer of bup on ArchLinux's AUR, and one user had the exact same issue. It seems like that was the cause, because when removing the folder with those problematic filenames it all worked again.

Maybe kup or bup should accept the same chars that Dolphin (Plasma)
Thanks for reporting! It seems many users are experiencing this after updating bup to version 0.31. Issue is reported and discussed here: https://groups.google.com/forum/#!topic/bup-list/Jaq_BACy7QU
(In reply to Rober from comment #4) > Sure, but what char is it? Maybe kup or bup should accept the same chars > that Dolphin (Plasma) Basically any non-ASCII character. It actually all works fine if you just use bup, this is a kup-specific bug. But yeah, it's definitely not an intended behavior; the fix should be on its way.
(In reply to João Figueiredo from comment #6) > this is a kup-specific bug Or, more accurately, there was a change in bup that kup didn't account for.
Done a little testing: 1. backup with kup without special-chars: works 2. backup with kup adding a file with special char: error 3. backup with bup (same options as kup): error 4. backup with bup without option "-vv": works (restore possible) 5. backup with bup with option "-v" (subfolder without special char): works 6. backup with bup with option "-v" (subfolder with special char): works (!) I have no idea, if this is helpful to anyone, or if it is even posted in the right place.
I think this has been fixed upstream. Found the following: https://groups.google.com/forum/#!topic/bup-list/Ifw6gZ6sxBA https://github.com/bup/bup/commit/eff166ca3ad17288b3114cc3c636c7b3d96ad155#diff-3f8c732e7bb07d7ef75a64f8effac28a So anyone who is eager enough to get this working can try latest bup from git.
Making the changes in io.py will result in an error message when trying to restore a file (w/o special chars) from an existing backup: Traceback (most recent call last): File "/usr/bin/bup", line 25, in <module> from bup.io import path_msg File "/usr/lib/bup/cmd/../bup/io.py", line 12 """Return a string representation of a path.""" ^ IndentationError: expected an indented block So I rather do not implement this as it would mean to loose all existing backups.
I like to confirm that the bug is fixed. Backup as well as restore works fine now. Whatever went wrong the first time, I've tried - most certain a mistake on my side - didn't show up again. Thank you and all the others for your time and effort in this matter as well as for your work in this tool in the first place.
