  5. For each provider in the list, use the DiskShadow tool's add and create commands to create a shadow copy of the volume for which the provider is responsible. If a provider is unable to create a shadow copy, contact the provider vendor if it is not Microsoft. If a Microsoft provider is unable to create the shadow copy, contact Microsoft Customer Service and Support. For more information, see https://go.microsoft.com/fwlink/?LinkId=102491.
