System State Restore
In the event of a complete Operating System loss a System State restore is required to get the device back up and running in its previous state.
Before attempting to perform a System State restore, it is necessary to prepare the target device to precisely match the machine the backup was taken from:
- Install an identical version of Windows
- Update Windows to the same service-pack level
- For Domain Controllers with Active Directory, ensure an empty Active Directory is created by running DCPROMO
The following steps outline the procedure required to ensure a successful restoration from a System State Backup to another device.
- Ensure the Backup Account of the failed system is inactive by disabling Backup & Recovery for the device
- From the Edit menu enable Backup & Recovery on the target device
- Click Use Existing Storage Account and select the Storage Account for the failed system from the list of Inactive Backups
- Backup & Recovery will install on the target machine with its status is displayed in the Summary tab of the Dashboard
For Domain Controllers with Active Directory, reboot the machine in Directory Services Restore mode
- Open the Backup Manager
- Go to the Restore tab and select the date of the backup to restore and click OK to restore from this backup set
- After the restore process completes it is necessary to reboot the machine
