Chapter 1 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
data with VSS without stopping work.
When backup is started by the backup software, VSSHP instantly creates a Shadow Copy of source
data using the ETERNUS Disk storage system Advanced Copy function. The source data is not
affected since the backup software performs backup of the Shadow Copy destination.
