Full System Recovery of SQL Server: Rebuilding the Operating System
In the case of disaster recovery, where a full system restore is required, you must first rebuild the system to exactly the state as it existed before the problem
- Rebuild the hardware if needed.
- Install the same version of the Windows operating system with the same patches that were previously installed.
- Configure the client with the same networking parameters and passwords that were previously set.
- Edit the host file of the client to include the CommServe name.
- Install the Windows File System Agent on the client.
In a clustered environment, you must reinstall to the same virtual node as was being used previously.
- Perform a full system restore of the Windows File System Agent.
What To Do Next

- if the SQL Server instance starts, use the steps in Restoring the SQL Server Instance to restore the data.
