Your company has a private cloud that is managed by using a System Center 2012 infrastructure.
You deploy Data Protection Manager (DPM) to the private cloud.
You configured DPM to back up the following information on 20 servers that run Windows Server 2008 R2:
* Data volumes
* System state data
* Volume mount points
You discover that the system state backup failes on all of the servers.
You can verify that all other data is backed up successfully.
You need to ensure that the system state backup completes successfully on all of the servers.
What should you do?
A.
Install Windows Server Backup on each server.
B.
Connect each server to a dedicated LUN.
C.
Reinstall the DPM agent on each server.
D.
Add each server to a dedicated protection group.
Explanation:
A system state backup uses the Windows Server Backup feature to take a snapshot of the system state and saves it locally to the server before moving it to the DPM server storage pool.Troubleshooting Data Protection Manager System State and Bare Metal Backup
