Symptoms

The PowerProtect Data Manager UI shows no failed backups, but the DPA report does show failed backups. 

The report source data is from the PowerProtect Data Manager API /api/v2/aggregation/protection-metrics

The API output shows a backup failure which confirms the issue is with PowerProtect Data Manager.

Cause

The request to "unable to delete storage unit" is treated as a protection task.
If there is an error when deleting a storage unit, the API reports a backup failure.

Resolution

Solution: From PowerProtect Data Manager 19.15, the error is not a backup failure.

Workaround: Fix the system error of "unable to delete storage unit".
