What does this mean and how to fix is? (I tried also with restic stable 0.11.0)

root@host ~ # ./restic_v0.11.0-221-g9c41e4a3_linux_amd64 check

I don’t recall seeing that type of data corruption in a Github issue, could you please open one?

The error is very likely caused by hardware problems: It seems like a bitflip occurred in the memory or CPU. (’#’ has the ascii code 0x23 and the probably correct number ‘3’ has 0x33.). Please run a memtest.
I suspect there might be some further hidden damage in the repository, so please run tell check to fully read every data file: restic check --read-data.

Would it be possible for you to help with investigating the damage to repository or do you want to repair the repository ASAP? If the repository is small enough a backup copy of it would be perfect to give us the possibility to further analyze the damage.

That said, to repair the repository you could try the steps from here: Data blobs seem to be missing, aborting prune to prevent further data loss! · Issue #3023 · restic/restic · GitHub . The initial command to find the problematic pack file would be restic find --show-pack-id --tree 35eb29dd. With the results from that you should be able to follow “Route 1”.

Thanks for all your help. It takes a lot of time but finally we have replaced servers RAM and everything seems to work now.
