No snapshot listing in log files


I scrolled through some old logs and noticed a change a couple of months ago. Previously, my logs had detailed listings of snapshots.

Now those details are missing. It says instead a lock could not be created:

processed 397712 files, 37.390 GiB in 19:26

snapshot c160ce91 saved

unable to create lock in backend: repository is already locked by PID 91718 on server by root (UID 0, GID 0)

lock was created at 2024-04-16 03:50:14 (1752h3m9.168068819s ago)

storage ID 818b69f3

the `unlock` command can be used to remove stale locks

There seems to be no error. Can’t remember I changed something lately, besides I upgraded from 0.14.0 to 0.16.4 today.

This line shows that there is a lock in the repository that was created over 1752 hours or 73 days ago. The prune command sees this lock and can only presume that it is not safe to continue pruning the repository, since a lock indicates that someone else is doing work in the repository.

The reason you are not seeing a list of snapshots is simply because that list of snapshots normally comes from your prune command, but in this case the prune never continues.

You can remove the lock with the unlock command as suggested in the output, that would make it work again.

Note that your backups were not stopped because of this, it’s just a problem with your pruning.

Yes, thanks. Did unlock.

This wasn’t covered in my backup script. Had no such thing before and it run for almost 2 years flawlessly. :slight_smile:
Will see if I can check for existing locks with list locks. Or perhaps remove locks automatically at the end of my script anyway.
