• Unified interface to VSS. VSS abstracts the shadow copy mechanisms within a common interface

while enabling a hardware vendor to add and manage the unique features of its own providers.

Any backup application (requester) and any writer should be able to run on any disk storage

system that supports the VSS interface.

• Multivolume backup. VSS supports shadow copy sets, which are collections of shadow copies,

across multiple types of disk volumes from multiple vendors. All shadow copies in a shadow copy

set will be created with the same time stamp and will present the same disk state for a multivolume

disk state.

• Native shadow copy support. Beginning with Windows XP, shadow copy support is available

through VSS as a native part of the Windows operating system. As long as at least one NTFS disk

is present on a system, these systems can be configured to support shadow copies of all disk systems

mounted on them.

Installing and configuring Microsoft VSS with VSM virtual disks

Use the following checklist to make sure that you implement all of the requirements for running VSS

on the VSM virtual disks presented by the DPMs. The checklist applies to each host that is using VSS.

These hosts include the application hosts and the hosts that back up the data to tapes or disks.

Configuration checklist for VSM deployment with VSS

• You are using an actual Windows server, not a Windows virtual machine on a VMware ESX

server, and the full-featured DSM has been installed.

• Confirm that the server is defined as a host in the HP Command View SVSP GUI.

• On the VSM, create a SAN CLI virtual disk and present it to the host.

• On the host, make sure that the SAN CLI virtual disk is recognized on Disk Management.

• On the host, install the SVSP VSS hardware provider. See “Installing the SVSP VSS hardware

provider on the host server” on page 98.

• On the host, configure the SVSP VSS hardware provider with a user that can access and manage

the SVSP domains.

• On the host, install the Microsoft hot fix KB891957, which fixes volume Shadow Copy Service

issues in Windows Server 2003. You can download KB891957 from http://support.microsoft.com/

kb/891957.

Installing the SVSP VSS hardware provider on the host server

NOTE:

For VSS to work correctly, you must first install the SVSP full-featured DSM.

You can install the SVSP VSS hardware provider using a single installation package. The final step

in the installation process automatically starts the SVSP VSS Hardware Provider Service.
