We recommend that you regularly back up the complete farm. However, business or IT requirements might require that you export a site, list, or document library. Regularly exporting sites, lists, and document libraries reduces data losses that might occur from hardware failures, power outages, or other problems. It is a simple process and helps to ensure that data is available for recovery, if that is required. You can only export one site, list, or document library at a time.

For information about what to back up and which tools to use, see Pianificare il backup e il ripristino (SharePoint Foundation 2010).

Procedures in this task:

  • Use Windows PowerShell to export a site, list, or document library

  • Use Central Administration to export a site, list, or document library

Nota

You cannot use SQL Server tools or Data Protection Manager to export a site, list or document library.

Task requirements

Before you begin, you must create a folder on the local computer or the network in which to store the export file. For better performance, we recommend that you export to the local computer and then move the export file to a network folder.

Use Windows PowerShell to export a site, list, or document library

You can use Windows PowerShell to export a site, list, or document library manually or as part of a script that can be run at scheduled intervals.

To export a site, list or document library by using Windows PowerShell

  1. Verify that you meet the following minimum requirements: vedere Add-SPShellAdmin.

  2. On the Start menu, click All Programs.

  3. Click Microsoft SharePoint 2010 Products.

  4. Click SharePoint 2010 Management Shell.

  5. At the Windows PowerShell command prompt, type the following command:

    Export-SPWeb -Identity <Site URL> -Path <Path and file name> [-ItemUrl <URL of site, list, or library>] [-IncludeUserSecurity] [-IncludeVersions] [-NoFileCompression] [-GradualDelete] [-Verbose]

    Nota

    If the <Site URL>, <Path and file name>, or <URL of site, list, or library> contain any spaces, you must surround these in double quotes (“ ”) or the Windows PowerShell command will return errors.

    If you are exporting a large site, list, or document library, you can use the GradualDelete parameter. When this parameter is used, the site collection is marked as deleted, which immediately prevents any further access to its content. The data in the deleted site collection is then deleted gradually over time by a timer job instead of all at once, which reduces its impact on the performance of farm servers and SQL Server.

    To specify which version of the site, list, or document library to include, use the IncludeVersions parameter and specify “LastMajor” (default), “CurrentVersion”, “LastMajorandMinor”, or “All”. To include the user security settings with the list or document library, use the IncludeUserSecurity parameter. If you want to overwrite the file that you specified, use the Force parameter. To view the progress of the backup operation, use the Verbose parameter.

    The NoFileCompression parameter lets you specify that no file compression is performed during the export process. Using this parameter can lower resource usage up to 30% during the export process. Using this parameter will result in a backup folder being created instead of a compressed file. If you use the NoFileCompression parameter in the Export-SPWeb command, you must also use it when you import the content by using the Import-SPWeb command.

For more information, see Export-SPWeb.

Nota

Per l'esecuzione di attività amministrative dalla riga di comando è consigliabile utilizzare Windows PowerShell. Lo strumento da riga di comando Stsadm è deprecato, ma è stato incluso per garantire la compatibilità con le versioni precedenti del prodotto.

Use Central Administration to export a site, list, or document library

You can use Central Administration to export a site, list, or document library. You can only export one site, list, or document library at a time.

To export a site, list, or document library 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, click Backup and Restore.

  3. On the Backup and Restore page, in the Granular Backup section, click Export a site or list.

  4. On the Site or List Export page, in the Site Collection section, select the site collection from the Site Collection list, and then select the site from the Site list.

  5. If you are exporting a site, skip this step, Select the list or document library from the List list.

  6. In the File Location section, in the Filename box, type the UNC path of the shared folder and the file to which you want to export the list or document library. The file name must use the .cmp extension.

  7. If the file already exists and you want to use this file, select the Overwrite existing files check box. Otherwise, specify a different file name.

  8. If you want to export all the security and permissions settings with the list or library, in the Export Full Security section, select the Export full security check box.

  9. If you want to specify which version of the list or library to export, select one of the following versions from the Export versions list:

    • All Versions

    • Last Major

    • Current Version

    • Last Major and Last Minor

  10. When you have specified the settings that you want, click Start Export.

  11. You can view the status of all backup jobs at the top of the Granular Backup Job Status page. You can view the status of the current backup job in the Content Export section of the page. 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 <file name>.export.log file at the UNC path that you specified in step 6.
