Before redirecting the restore of a SharePoint Portal Server database, the SharePoint Portal Server software must be installed on the target server.
When you restore a SharePoint Portal Server database, all SharePoint data on the target server is overwritten.
To redirect a SharePoint Portal Server restore job
Place the media containing the data you want to restore in the storage device.
Navigate to and select the SharePoint Portal Server database you want to restore.
On the Properties pane, under Destination, click Microsoft SharePoint Redirection.
In the Restore to server field, enter the name of the SharePoint server to which you are restoring. Use the following format: \\servername.
Use the default logon account as indicated, or click Change to select a different one.
On the Properties pane, select other job properties that might be appropriate for your environment.
After the restore completes, it is recommended that you perform a full backup of the restored SharePoint Portal Server databases.
