NetBackup status code: 1501
Explanation: The source that you specify for one or more duplication destinations in storage lifecycle policy is not valid.
Recommended Action: Do the following, as appropriate:
Verify that the specified source refers to a valid destination in the list of destinations in storage lifecycle policy.
Verify that the Backup or Snapshot destination type does not have any source specified. If you use nbstl to configure storage lifecycle policy, use value zero (0) as the source for a backup or a snapshot destination type.
Verify that the destination that refers to the specified source is not a Snapshot destination type. NetBackup cannot duplicate a backup image that uses snapshot copy as a source.
Verify that the specified source does not refer to the destination itself for which the source is mentioned.
Verify that the specified list of destinations in a storage lifecycle has a circular dependency for the source.
For cloud snapshot replication, the source must be snapshot operation.
