In this recipe, we'll enable Windows bare metal and System state protection. The System state backup enables you to recover when a machine starts but you've lost system files and registry. A System state backup includes the following:
- Domain member: Boot files, COM+ class registration database, registry
- Domain controller: Active Directory (NTDS), boot files, COM+ class registration database, registry, system volume (SYSVOL)
- Machine running cluster services: Additionally backs up cluster server metadata
- Machine running certificate services: Additionally backs up certificate data
On the other hand, Bare Metal Recovery, known as BMR, is useful. By definition, it includes a System state backup; for instance, it provides protection when a machine won't start and you have to recover everything.
