Executing an FRS recovery

Use the Recovery feature to restore a production storage group from an

1.Click Recovery on the main window menu bar, and select Roll-Forward Recovery or Point-in-Time Recovery.

Roll Forward Recovery

Use Roll Forward Recovery if the production storage group's database(s) becomes damaged but the storage group's transaction logs are known to be unaffected.
