title: Hyper-V back up VHD live with PowerShell
body: <p>I've heard people say that you can back up VHD files on Windows 2008 R2 Hyper-V (non clustered) and back them up while the guest is live and running with powershell scripts. Does anyone have any experience of this they can share?</p>
  
  <p>What kind of back up is it an export? A Snapshot that is made, then copied then reverted? I know there are copious pay-to-use models but this is a test environment and I simply want to know if there is a "weak but functional" way of doing it.</p>
