ETERNUS VSS Hardware Provider
1.1 Overview
ETERNUS VSS Hardware Provider (hereinafter referred to as "VSSHP") is a program that is
compatible with the Microsoft Volume Shadow Copy Service (hereinafter referred to as "VSS")
interface, and that creates shadow copies of volumes in an ETERNUS Disk storage system.
Using VSSHP with VSS-compatible backup software or a server application enables you to backup

affected since the backup software performs backup of the Shadow Copy destination.
