Abstract
Described herein are techniques for configuring a volume shadow copy service (VSS) requester and/or VSS provider so that a snapshot may be taken of application data stored on a virtual volume (VVOL). The VSS requester may receive a request to take a snapshot of a VVOL, the VVOL identified by a VVOL identifier. The VSS provider associated with a storage array may determine whether the storage array supports taking the snapshot of the VVOL. The determination may be based on information derived from a mapping which maps respective VVOL identifiers to respective logical unit identifiers. If the VSS provider supports taking the snapshot of the VVOL, the VSS provider may take the snapshot of the VVOL.
