NetBackup status code: 3019
Message: Base snapshot ID is unknown to get diff.
Explanation: There is no full backup snapshot ID to get the vendor change tracking information.
Recommended Action: Perform the following, as appropriate:
Update the policy schedule to create full backup first and then create an incremental backup.
When a new NAS volume is added or discovered in the NAS-Data-Protection policy, perform a backup using the full schedule.
Adjust the snapshot copy retention setting to ensure that the snapshot is available when an incremental backup starts.
