What is system state backup?

Windows Server 2012 allows you to take system state backup which will back up operating files. You are able to recover the operating files when your machine starts but you've lost system files and registry. System state data is composed of the following files:

  • Boot files, including the system files, and all files protected by Windows File Protection (WFP).

  • Active Directory (on a domain controller only).

  • Sysvol (on a domain controller only).

  • Certificate Services (on certification authority only).

  • Cluster database (on a cluster node only).

  • The registry.

  • Performances counter configuration information.

  • Component Services Class registration database.

The system state data can be backed up in any order. Restoration of the system state replaces boot files first and commits the system hive of the registry as a final step in the process.

System state backup and restore operations include all system state data: you cannot choose to backup or restore individual components due to dependencies among the system state components. However, you can restore system state data to an alternate location in which only the registry files, Sysvol directory files, and system boot files are restored. The Active Directory database, Certificate Services database, and Component Services Class Registration database are not restored to the alternate location.

Although you cannot change which components of the system state are backed up, you can back up all protected system files with the system state data by setting advanced backup options.

How to take system state backup in Windows Server 2012 (R2) step by step?

First install the feature of Windows Server Backup on Windows Server 2012 and then follow the steps below to take system state backup.

Step 1. Open Server Manager and enable Windows Server Backup from the features. Click Start, Administrative Tools, and then select Windows Server Backup.

Step 2. On the Windows Server Backup page: click on Backup Once. Or you can also make a scheduled backup by clicking Backup Schedule.

Step 3. On the Backup Options page: choose Different options and click Next.

Step 4. On the Select Backup Configuration page: select Custom and click Next.

Step 5. On the Select Items for Backup page: click Add Items to select the option of System State Backup.

Step 6. On Select Items page: select System State and click OK.

Step 7. On Select Items for Backup page: confirm the items to be included in a backup and click Next to continue.

Step 8. On the Specify Destination Type page: choose Local drives and click Next. Or you can select Remote shared folder to store the backup to any share folder.

Step 9. On the Select Backup Destination page: choose the destination drive and click Next.

Step 10. On the Confirmation page: verify all options and click Backup to start.


Step 11. When the backup is completed, click Close to close the Window.

It may take a long time to finish the backup. And there are two points you should pay attention to:

  • Once the backup is complete, if you want to create another backup, you must specify the destination to another location because the new backup will overwrite the previous backup on the same location.

  • If what you created is a scheduled backup, you can modify or delete the task when you want to create a new scheduled backup.
