What Is System State Backup?

Windows system state backup contains the following:

• Windows System Registry.
• Performance Counter Configuration information.
• Component Services Class registration database.
• Boot and system files, including those protected by Windows File Protection (WFP).
• The configuration of system-dependent Microsoft applications, such as Certificate Services, Active Directory, IIS etc.

This backup type is typically quite small small in size but can cause a large amount of changes for incremental forever backup solutions as any updates applied to the system will cause the System State to be modified. 

It can help you solve such issues as:

• configuration-dependent system faults (for example, BSOD errors).
• crucial file or system registry corruption of any kind.
• To perform a Bare Metal Recovery (BMR) of the protected server.
