Troubleshooting SharePoint jobs that use Granular Recovery Technology (GRT)

Note the following when you use NetBackup to perform backup or restore operations using Granular Recovery Technology:

  • Disable or uninstall QLogic SANSurfer software. It may conflict with the portmapper for Client for NFS.

  • Before you install NFS on the media server or client(s), look for the ONC/RPC Portmapper service. If it exists, stop it and disable it. Otherwise, the installation of NFS Services for Windows fails.

  • SharePoint GRT operations can fail for the VM backup images that use display names that contain parenthesis. For example, a GRT live browse restore from the Backup, Archive, and Restore (BAR) interface fails with the following error:

    database system error

  • In the Local Security Settings, the Users group must have User Rights Assignment "Allow log on locally". By default, the Users group is included. If the Users group does not have this right, the following error occurs:

    1385 -- Logon failure: the user has not been granted the requested logon type at this computer.

  • Backups of the SharePoint web applications that use Granular Recovery Technology (GRT) and that contain a larger number of content databases (100+) may timeout. In this situation, increase the default "Client read timeout" setting to 900 seconds.

  • NetBackup supports GRT restores of large documents for SharePoint with SQL Server using SQL Server Native Client 10.0 or later.

  • Technical Support may want nbfsd logs from the media server. Use the Verbose setting carefully as the nbfsd log can grow very large.
