Solution



GRT provides the ability to recover:

  • Individual files and folders. This is called file/folder-level GRT.
  • Individual items from Microsoft Active Directory, Exchange, SQL, and SharePoint. This is called application-level GRT.

The limitations of file/folder-level GRT and application-level GRT for certain Windows Server 2012 features are listed below:
