Before redirecting the restore of SharePoint 2007 document library data, the SharePoint Portal Server software must be installed on the target server. If any of the folders in the original document library do not exist in the destination document library, they will be created during the restore.
To redirect the restore of SharePoint 2007 document library data to another document library
Navigate to and select the SharePoint document library data you want to restore.
On the Properties pane, under Destination, click Microsoft SharePoint Redirection.
Click Individual SharePoint sites, documents, lists, or items.
Click Restore to workspace or document library (Web Storage System-based only).
In the Restore to server field, type the name of the SharePoint server to which you want to restore.
In the Restore to workspace or document library field, type the name of the document library to which you are restoring.
If you have not yet created the document library, you must do so before you start the restore operation.
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.
