PowerProtect Data Manager 19.9 Microsoft Application Agent Exchange Server User Guide

Troubleshooting storage units

When you add a protection policy or create a storage unit in PowerProtect Data Manager, storage unit creation fails if you reach the maximum MTree and Users count on the selected DD system.

PowerProtect Data Manager enables you to finish adding a protection policy without a storage unit. However, if you subsequently run a backup with this protection policy, the backup process is suspended indefinitely with no error message.

To continue backup operations, you must perform a cleanup on the DD system.
