We had similar errors this week after upgrading our node to the 5.4.4 client from 5.3.3. I found helpful information at the windows tech support web site just by doing a search on the error text. We fixed our issue by changing the service 'Microsoft Software Shadow Copy Provider' from disabled to manual. That is in addition to already having the 'Volume Shadow Service' service set as manual also.
