Back up a Web application (Search Server 2010)

We recommend that you regularly back up at the farm level. However, business or IT requirements might require that you back up a Web application. Regularly backing up a Web application reduces the possibility of data losses that might occur from hardware failures, power outages, or other problems. It is a simple process that can help to ensure that all the Web application-related data and configurations are available for recovery, if that is required.

You can only back up one Web application at a time using this procedure. However, you can simultaneously back up all Web applications by backing up the entire farm.

Performing a backup does not affect the state of the farm. However, it does require resources and might slightly affect farm performance when the backup is running. You can avoid performance issues by backing up the Web application during hours when farm use is lowest, such as outside office hours.

This topic describes how to back up a single Web application.

Procedures in this topic:

Before you begin, you must create a network folder in which to store the backups. Both the Windows SharePoint Services Timer V4 service account and the server farm user account must have Full Control permissions to this folder.

You can use Windows PowerShell to back up a Web application manually or as part of a script that can be run at scheduled intervals.

To back up a Web application by using Windows PowerShell
  1. Verify the following: See Add-SPShellAdmin. Additionally, the user account performing this procedure must be a member of the SQL Server db_backupoperator fixed database role on the database server where each database is stored.

  2. In the SharePoint 2010 Management Shell, at the Windows PowerShell command prompt, type the following command:

    Backup-SPFarm -Directory <BackupFolder> -BackupMethod Full -Item <WebApplicationName> [-Verbose]
    

    Where:

    • <BackupFolder> is the path of the network folder in which you want to store the backups.

    • <WebApplicationName> is the name of the Web application that you want to back up. To display the name of the Web application, at the Windows PowerShell command prompt, type the following command: Backup-SPFarm -ShowTree.

    To view the progress of the backup operation, use the Verbose parameter.

    noteNote
    If you are backing up the Web application for the first time, you must use the Full option. You must perform a full backup before you can perform a differential backup.

    For more information, see Backup-SPFarm.

  3. If you do not use the Verbose parameter, the Command Prompt window displays no message if the operation succeeds. If the job does not finish successfully, the Command Prompt window displays an error message such as the following:

    Backup-SPFarm: The operation failed. For more information, see the error log that is located in the backup directory. At line: <line> char:<column>. + <cmdlet> <<<< <location of error>
  4. If there are errors or warnings, or if the backup does not finish successfully, review the Spbackup.log file in the backup folder.

You can use Central Administration to back up a Web application.

To back up a Web application by using Central Administration
  1. Verify that the user account that is performing this procedure is a member of the Farm Administrators group.

  2. In Central Administration, on the Home page, in the Backup and Restore section, click Perform a backup.

  3. On the Perform a Backup — Step 1 of 2: Select Component to Back Up page, select the Web application from the list of components, and then click Next.

    noteNote
    The Web application might consist of several components. You must select the top-level component.
  4. On the Start Backup — Step 2 of 2: Select Backup Options page, in the Backup Type section, select either Full or Differential.

    noteNote
    If you are backing up the Web application for the first time, you must use the Full option. You must perform a full backup before you can perform a differential backup.
  5. In the Back Up Only Configuration Settings section, click Back up content and configuration settings.

  6. In the Backup File Location section, type the Universal Naming Convention (UNC) path of the backup folder, and then click Start Backup.

  7. You can view the general status of all backup jobs at the top of the Backup and Restore Job Status page in the Readiness section. You can view the status for the current backup job in the lower part of the page in the Backup section. The status page updates every 30 seconds automatically. You can manually update the status details by clicking Refresh. Backup and recovery are Timer service jobs. Therefore, it may take several seconds for the backup to start.

    If you receive any errors, you can review them in the Failure Message column of the Backup and Restore Job Status page. You can also find more details in the Spbackup.log file at the UNC path that you specified in step 6.

You cannot back up the complete Web application by using SQL Server tools. However, you can back up all the databases that are associated with the Web application. To back up the complete Web application, use either Windows PowerShell or Central Administration.

To back up a Web application by using SQL Server tools
  1. Verify that the user account that is used to back up the databases is a member of the SQL Server db_backupoperator fixed database role on the database server where each database is stored. Additionally, verify that the user account has Full Control permissions on the backup folder.

  2. Open SQL Server Management Studio and connect to the database server.

  3. In Object Explorer, expand Databases.

  4. Right-click the database that you want to back up, point to Tasks, and then click Back Up.

  5. In the Back Up Database dialog box, in the Source area, select the kind of backup that you want to perform from the Backup type list. For more information about which backup type to use, see Overview of Recovery Models (http://go.microsoft.com/fwlink/p/?LinkId=114396).

  6. In the Backup component area, click Database.

  7. Either use the default name provided or specify a name for the backup set in the Name text box.

  8. Specify the expiration date for the backup set. This date determines how long, or when, the backup set can be overwritten by any later backups that have the same name. By default, the backup set is set to never expire (0 days).

  9. In the Destination area, specify where you want to store the backup.

  10. Click OK to back up the database.

  11. Repeat steps 1-10 for each database that is associated with the Web application.
