Quantum VSS Writer

Enable the Quantum Volume Shadow Copy Service (VSS) Writer to perform VSS backups for Windows-

based virtual machines (VMs) on an Active Directory (AD) Domain Controller.

The VSS Writer prepares Windows for a VMware snapshot to back up the VM's data. It then automates a

non-authoritative restore of the Windows AD Domain Controller when the VM is restored.

When you restore a Windows AD Domain Controller from a snapshot image, the vmPRO appliance

automatically boots the VM in the restore mode and performs necessary steps to prevent an update

sequence number (USN) rollback. These steps ensure that directory replication works correctly.
