Restic check failures after upgrading to 0.9.0

Getting Help
1

Hi folks,

I’m having trouble with “restic check” failing on my local repository after upgrading to 0.9.0. The first backup took a long time, as mentioned in the release notes, and succeeded, but after this first backup and subsequent backups, I’m getting fatal errors when running “restic check”. I run “restic check” after every backup or prune operation and it has run clean on every backup and prune before the upgrade.

Here’s what check shows:

using temporary cache in /tmp/restic-check-cache-207486998
create exclusive lock for repository
load indexes
check all packs
check snapshots, trees and blobs

Fatal: repository contains errors

I tried “rebuild-index” already but that did not help. Can you please advise on how to recover my repository from these errors? Can I delete the snapshots with the errors and move on? Thanks.

Oh, interesting, that’s a bug! Does it happen all the time?

Would you mind filing a new issue on GitHub so we can find out what’s going on? Thanks!

Your repository and the snapshots therein are fine by the way, there’s just something odd going on with the temporary cache restic check creates during the check. You can disable it by running restic check with the option --no-cach (although then the check will take longer).

Thanks for the reply, fd0, and thanks for confirming it is a check cache issue and not a problem with my repository!

It happened yesterday after my first manual backup after upgrading to 0.9.0 and again this morning after my scheduled daily backup ran. The second backup has more errors shown than the first. I will try with --no-cache and see how it goes.

I will open a GitHub issue later today when I have access to the computer again to provide all of the requested information in the issue template. I’ll update this thread when I do so. Thanks again!

I opened the following issue: https://github.com/restic/restic/issues/1833

Thanks again for the quick assistance, fd0. I did verify that restic check works and reports no errors in my repository when I use --no-cache.
