Recovering a SharePoint Web application in a farm with multiple front-end servers
To restore a deleted web application in a Network Load Balanced (NLB) farm, you may need to perform a manual operation using the SharePoint Central Administration interface. After the restore operation is successful, if the Web application on the NLB farm is offline, perform the following steps.
Note:
After you complete the following steps, a change is reflected in the IIS attributes for the primary configured balanced node. The new balanced load server contains two sites: the original site and the name of the latest site that you create in step 13. However, both sites link to the original site and there is no effect on the environment.
To recover a SharePoint Web application in a farm with multiple front-end servers
- Log on as Administrator.
- Open the Backup, Archive, and Restore interface.
- Choose File > Select Files and Folders to Restore > from Normal Backup.
- Select the MS-SharePoint policy type.
- Click OK.
NetBackup browses for SharePoint Server backup images.
From the NetBackup History pane, select the images that contain the objects you want to restore:
The last full backup, or
The last full backup and all subsequent differential backups
- In the All Folders pane, expand Microsoft SharePoint Resources and the Web application.
Note:
When you select items to restore, do not check the checkbox for an item in the All folders pane. Only check the checkbox for an item in the Contents of pane.
- In the Contents of pane, select the Content database.
- Restore the database to the primary front end.
Note that you only need to perform this action once.
- Open the SharePoint Central Administration interface.
- Under Central Administration, click Application Management.
- Under SharePoint Web Application Management, click Create or extend Web application.
- Select Extend an existing Web application.
- Do the following to extend the Web application:
Click on the link for the Web application and select Change Web Application. Fill in the values to extend the restored Web application.
Select Create a new IIS web site and fill in the information to match the original Web application. However, you cannot use the same port number.
In the Load Balanced URL section, provide the node name of the load balanced server. (For example, http://VMSP-3:new port.)
- After you complete step 14, all other configured front-ends may be automatically updated with IIS entries. If so, no further action is required.
If other front-ends require load balancing, then repeat step 12 through step 14.
