Home > Data Protection > PowerProtect Cyber Recovery > Dell EMC PowerProtect Cyber Recovery: Automated Recovery of PowerProtect Data Manager > Vault environment
Ensure that your vault environment meets the following requirements:
For example, when a backup is completed using PPDM, the DD Boost user is automatically created in the production DD series appliance with a UID (for example, 528). When you initiate an automated recovery of PowerProtect Data Manager, Cyber Recovery attempts to create same DD Boost user on the vault DD series system with the same UID (528). If that UID is assigned to another user, recovery will fail. You must keep that UID available in the vault DD series system for a successful recovery.
