To redirect a restore job for SharePoint 2003
You must create the destination SharePoint Portal Server 2003 portal site or Windows SharePoint Services site on the specified Web server with the same database structure as the source site before you run the restore job.
To bring the databases online, verify that the Bring restored databases online and Reconnect previous database links options are selected in the Microsoft SharePoint settings. When you restore portal sites or Windows SharePoint Services sites, these options also re-establish the link between the restored databases and their corresponding sites.
If you restore full or differential backup sets in separate restore jobs, clear these options for all jobs except the last job. You should select these options for the last restore job in the sequence. You may be prompted to insert any media that you have already used.
