An NDMP snapshot policy for wildcard backup fails with error 4201
An NDMP policy for wildcard backup fails when the policy is run after the image expires. In this scenario, the policy has a specific retention period after which the image expires. If a backup is taken immediately after the specified retention period the backup automatically fails. The backup fails due to the conflict in snapshot creation as the DFM server takes some time to delete the existing snapshot-related information.
For a successful backup, run the backup job after some time.
