    Question

  • Hi all,

    I have a customer who has certain storage devices that do not support Microsoft Volume Shadow Copy, e.g. the Drobo series of direct attached storage devices,so whenever he tries to backup any of these drives and when the backup software use VSS, the system gets locked up and these errors and warnings appears in event viewer:
