What Is System State Backup?

To learn what a system state backup is, first of all, you need to know what a system state is. A system state contains some system settings and parameters files that are listed in the next part.

System state backup is a copy of system state data created by certain tools and stored in a safe location. Once the original system state files are damaged or missing, you can rely on the backup image to recover the previous working system.

To make system state backup, there are many available tools including the built-in Windows Server Backup and Wbadmin, and third-party programs like MiniTool ShadowMaker.

What Does System State Backup Include?

What system state backup contains? System state data contains the below files:

  • Boot files like the system files and all files protected by WFP (Windows File Protection).
  • Active Directory (AD) on a domain controller (DC) only.
  • Sysvol on a DC only.
  • Certificate Services on a certification authority only.
  • Cluster database on a cluster node only.
  • The registry.
  • Performance counter configuration information.
  • Component Services Class registration database (COM+).

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

For the dependencies among the system state components, you are not able to select individual files to backup or restore. Thus, the system state backup and restore process contain all system state data. Yet, you can restore system state data to an alternate location in which only the system boot files, registry files, and Sysvol directory files are restored.

Although you cannot alter the system state backup source, you can back up all protected system files with the system state data by setting advanced backup options. To set up advanced backup options, just follow the below steps.

  1. In the Backup window, go to the Backup tab and choose the files and folders you’d like to protect.
  2. Select Start Backup.
  3. On the Backup Job Information screen, click Advanced.
  4. Specify the advanced backup options that you prefer and click OK.
  • Back up data that is in Remote Storage: Backs up data that has been designated for Remote Storage. You can restore Remote Storage data only to an NTFS volume that is used with Windows 2000.
  • Verify data after backup: Verifies that the backed-up data is exactly the same as the original one. This might increase the whole process time.
  • If possible, compress the backup data to save space: Compress the data you are backing up to store more data on a tape. If this option is disabled, it means you don’t have a tape drive on your computer or your tape driver can’t compress data.
  • Automatically back up system-protected files with the system state: Backs up all of the system files that are in your %SystemRoot% directory in addition to the boot files that are included with the system state data. This will increase your backup source size.
