A system-state recovery (SSR) is an online recovery that enables you to recover an online or powered-on machine that has lost its system files and registry. Perform an SSR when you want to restore certain operating system files from a known good backup to replace the corrupted or missing file. You can perform granular recoveries of selected writers from backed up bare-metal recovery (BMR) or SSR data. You can recover all system files in the backup to their original location only. Recovering the data to alternate hosts or locations is not supported.
The following list includes examples of files and components that are in an SSR:
- Boot files
- COM+ class registration database
- Registry and IIS metadata
- Active Directory (NTDS)
- System volume (SYSVOL)
If system files or registry entries are lost, you can recover the relevant writers and perform an SSR.
