Interrupted backup - datastore verification failed

Hello there,
recently i had backup of LXC running (from ProxmoxVE) but it got interrupted by electricity outage. Now i cant see the backup anywhere, it does not existi in GUI, neither in filesystem directory, but it is getting verified for some reason, which leads to verification error.
I wonder if there is some index of backups, which the verification reads from.

Verification error:
2023-08-08T04:26:57+02:00: verify pbs-backup:ct/103/2023-08-07T15:30:05Z - manifest load error: unable to load blob '"/mnt/pbs-backup/ns/cutter-pve/ct/103/2023-08-07T15:30:05Z/index.json.blob"' - No such file or directory (os error 2)

The backup folder does not exist:
ls /mnt/pbs-backup/ns/cutter-pve/ct/103/2023-08-07T15:30:05Z/
ls: cannot access '/mnt/pbs-backup/ns/cutter-pve/ct/103/2023-08-07T15:30:05Z/': No such file or directory

So the question is why the verification is processing backup that does not exist and how to stop it.

Thanks in advance

Hi, this should not happen as the verify job checks if the snapshot directory exists before even trying to get the index file. Can you also share the full output of the verify job? DId you also try to re-run the verify job for that backup group?

Edit: Please also provide the output of proxmox-backup-manager version --verbose

Hi, the problem does not appear anymore, the next verify job did went successfully. Maybe it got fixed after garbage collector?
