Background note:

Back up the target volume vol-002 to the remote nfs server, and then restore the volume that has been backed up to the nfs server. During the recovery process, the nfs server is down, and the recovery volume has been in a state of 'restoring' and cannot be deleted. This article records the whole process of backup recovery and final deletion.
