Velero 1.9.1

We may make the enhancement like this:

• We define a max retry count, if it exceeds the count, the current prune will be skipped. The prune will be retried at the next prune due time
• Use exponential backoff algorithm for the retries

Experiencing the same issue here.

Just manually removing the lock file in the Restic repository without uninstall/reinstall and then starting a new backup seems to work on my end. <- Edit: Actually it doesn't sorry, other backups are still failing.

Try to increase the velero container requests/limits.
