Repo corupted - failed to open repository

Support
1

Hi,

Been runing Kopia UI on my desktop (Windows 10) PC for a year of two. No issues so far.

But yesterday I noticed that my Kopia is not connecting to repo. It might have happened there was an unplaned hard restart of the computer in prior days…

Anyway any ideas how to fix?

Here is part of log (it repeats so I think it should be enough):

  1. I have tried removing the index file
    **error decrypting BLOB xn83_a104cb99c18f25217fe9804f246b952b-s98a6af042a972038139-c1: Error computing ECC: no shard data
    **
    That did not resolve the issue.

  2. I have tried removing a week of indexes files from “..cache\repository\indexes” but that did not change anything.

Any ideas how to recover?

2

I must have somehow lost the entire indexes subfolder. Windows Explorer operation when I tried selecting and or drag and droping… I only have a dozen of latest *.sndx files that moved to temp folder.

Anyway i think this probably means that repo is lost and I would need to setup a new repo from scratch?

3

I might have fixed it….

In the mean time I noticed some of the .repositories\cache\ subfolders went missing.

Anyway…I actually went and found the offending BLOB file which I found in: E:\BackupMain\repositories\BackupMain\xn8\3_a\104a…139-c1.f

It was the newest timestamp and empty (no contents). After I deleted the 104a..139-c1.f file I could reconnect to my repo.

And on first look it looks like data and history is there.

Should I verify?

Only if you don’t believe that you are always lucky:)
