If you are facing an error while you are trying to restore: “Restore must be resumed prior to first image expiration on”

1. There can be another restore process using the same resources, or a restore job is stuck. Try to resume your restore after the other restore finishes. If the restore job is stuck check netbackup/db/jobs/restart/ directory, there should be no jobs in this directory after all jobs are finished. Delete the files if there are any.

2. You might have selected multiple backup images at the same restore job. Try to restore every image one by one…

3. The image you’re trying to restore is about to expire and this message is given:  In order to be able to restore this image you need to resume your restore before the first image is expired.
