13 snapshots

TL;DR: Sometimes I get “no such file or directory” errors when trying to list snapshots (or other operations), and I see the locks being created, and deleted, over and over in the locks folder. If I cancel, and try again, it usually works immediately.

Which backend are you using? The compression support doesn’t change anything about lock handling so I’d be surprised if it causes that behavior.

The initial snapshots call had already completed all retries, so it should just have printed the snapshots list at that point (after 15 seconds).

3

It’s a local drive, which makes it even weirder. The drive checks out. SMART data seems OK. Not sure what’s going on.

That’s indeed very odd. It would be interesting to get a debug log of when that problem occurs again, see restic/CONTRIBUTING.md at master · restic/restic · GitHub for instruction to generate such a log.
