unable to create lock in backend

[amarendra]

For the last 4 days I see that the backups have been failing due to lock issues which was created 4 days ago. These are scheduled backups. (Also the last successful operation was also a backup).

To Reproduce These are scheduled backups so I am not sure what could be the steps to reproduce.

Expected behavior As the logs suggest the tool should at least try to unlock to remove the stale locks.

Platform:

• macOS 15.1
• Backrest Version 1.6.1
• restic-0.17.1

Additional context I am not sure whether this should be raised on restic Guthub repo or whether a latest restic version has fixed this but since I am on latest backrest I thought I shall start here.

Hi— first thing coming to mind is that Auto Unlock is disabled by default and must be opted in. Did you turn it on in the settings for your repo?

Did you turn it on in the settings for your repo?

My bad. I had not. Just did it. Thanks a lot!
