AhsayOBM allows you to back up the Windows System State with the Windows System State Backup Set.

Windows System State backup and restore operations include all system state data, and you cannot choose to backup or restore individual components due to dependencies among the system state components. System State data are comprised 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)
• Component Services Class registration database
• Performance counter configuration information
• Microsoft Internet Information Services (IIS) meta directory (on an IIS server only)
• Registry

The size of a set of system state backup data is dependent on the role installed on the server. Please refer to the following article for more details:

• For Windows XP and Windows Server 2003: https://msdn.microsoft.com/en-us/library/windows/desktop/aa381498
• For Windows 2008 and newer releases: https://msdn.microsoft.com/en-us/library/windows/desktop/bb968830
