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.

Classification Description

Requester Backup software that controls creation, operation, and deletion of a

snapshot through VSS. Backup software examples:

ETERNUS SF AdvancedCopy Manager, Microsoft System Center Data Protection Manager, Symantec Backup Exec, Symantec NetBackup, Quest NetVault Backup, CA ARCserve Backup, NetWorker, etc.

Writer Server application, which is a data management application that supports

VSS. Writer controls data consistency maintenance for data backup. Server application examples:

System writer (NTFS file system), Microsoft Exchange Server SQL server, Hyper-V VSS Writer, Oracle Database, etc.

ETERNUS VSS Hardware Provider 2.1 User’s Guide

Chapter 1 ETERNUS VSS Hardware Provider

1.2 Functions

Classification Description

Provider Component that reads and writes data to a disk and creates a snapshot

(software provider provided by OS, hardware provider provided by storage system vendor). VSSHP is a hardware provider that is provided by Fujitsu.

Coordinator (OS) Basic service that properly controls requester, writer, and provider process.

For VSSHP supported storage systems, copy types, OSes, requester, and writer, refer to the following web page.

http://www.fujitsu.com/global/services/computing/storage/eternus/tools/vsshp.html

1.2 Functions

■ Cooperation with Advanced Copy functions

VSSHP uses the Advanced Copy functions of the ETERNUS Disk storage system to create a Shadow Copy. The Advanced Copy functions allow the ETERNUS Disk storage system to carry out high-speed data copying operations on its own, with no need for server CPU intervention. The logical copy of a source volume to a replication volume is very quickly completed within the ETERNUS Disk storage system. The replication volume is accessible as soon as the logical copy completes. The replicated volume is a point-in-time copy of the source volume, allowing backup to tape while the source volume is being updated.

■ Management methods and operation modes for Shadow Copy destination volumes

with VSSHP

The following two operation types for VSSHP are supported. Which method is used depends on how the volumes for the Shadow Copy destination are managed.

• Target disk pool operation

The user does not specify the Shadow Copy destination explicitly.

• Copy set operation

The user specifies the Shadow Copy destination explicitly.

Both of these modes cannot be used at the same time.

■ Target disk pool operation

Although VSSHP creates a Shadow Copy of a source data, a user does not need to specify the volume that is to be a Shadow Copy destination. VSSHP manages Shadow Copy destination volumes that are registered in a target disk pool. This management function for Shadow Copy destination volumes is called the "Target disk pool management function". An operation mode that uses this function is called a "Target disk pool operation".

Create a Shadow Copy destination volume and register the volume in the target disk pool management function in advance. When backup is started by a requester, VSSHP automatically selects an appropriate volume from the registered volumes in the target disk pool, and creates a Shadow Copy of the source disk in the volume. After backup has completed, data in the Shadow Copy destination volume become invalid, and the volume is reused as a Shadow Copy destination at next backup.

ETERNUS VSS Hardware Provider 2.1 User’s Guide

Chapter 1 ETERNUS VSS Hardware Provider

1.2 Functions

When installing VSSHP, use ETERNUS Web GUI to register a volume in the target disk pool management function. Register the same number of source data volumes that will be backed up simultaneously. A volume can be added or deleted in the target disk pool management function even after installation of VSSHP has completed.

The copy types that VSSHP uses for the target disk pool operation are "QuickOPC" and "SnapOPC+".

■ Copy set operation

When a Shadow Copy of the source data is created by VSSHP in cooperation with ETERNUS SF AdvancedCopy Manager, the user needs to specify the volume for the Shadow Copy destination explicitly. VSSHP manages the Shadow Copy destination volume with the copy set information. This operation mode for a Shadow Copy destination volume that uses the copy set information is called a "Copy set operation". The copy set information registration command is used to register a volume to the copy set information. Refer to "ETERNUS VSS Hardware Provider 2.1 Copy Set Operation Technical Guide" as well as this manual for more details about copy set operation.

• A target disk pool operation and a copy set operation cannot be performed at the same

time.

• Do not register the copy set information when a target disk pool operation is being

performed. For details on operation modes and management files, refer to "1.3.3

Management Methods and Management Files" (page 23).

1.3 Operational Procedure

1.3.1 Server Configuration

VSSHP supports the following server configurations. These configurations depend on the requester to be used. Check which configuration is supported by the requester and decide the server configuration.

• Configuration using one Windows server that works as both a production server and a backup

server (hereafter referred to as "Local Copy Configuration")

• Configuration using different Windows servers for the production server and backup server

(hereafter referred to as "Transportable Copy Configuration")

To back up a virtual machine on a host OS in which Hyper-V is installed, refer to "1.3.1.3

Configuration (when Backing Up a Hyper-V Virtual Machine)" (page 20) or "1.3.1.4 Transportable Copy Configuration (when Backing Up a Hyper-V Virtual Machine)" (page 21).

For all other cases, refer to "1.3.1.1

Copy Configuration" (page 18).

For Hyper-V settings, only virtual machines on the host OS are targeted for backing up.

1.3.1.1 Local Copy Configuration

• Used as both the production server and backup server.

• A requester and writer that support VSS are installed in the same server.

1.3 Operational Procedure

• When VSSHP is installed in a host OS that controls the Hyper-V setting, VSSHP supports backup

processes. In this case, only a guest OS disk on the host OS is used as the target for backup processes.

• Backup processes for Local Copy Configuration and Transportable Copy Configuration are not

supported when VSSHP is installed in a guest OS that uses the Hyper-V setting.

1.3.2 Disk Conditions

The following conditions apply for source disks to be used for backup.

• MBR and GPT can be used for the partition format.

• A dynamic disk cannot be used. When it is used, operation is not guaranteed.

1.3.3 Volume Management Methods and Management Files

One of the following management files is created according to the management method for the Shadow Copy destination volume.

• Target disk pool management file

"installation folder"\etc\vss\bkdskpl.mng

• Copy set management file

"installation folder"\etc\vss\copyset.cnv

Unnecessary management files may exist due to a reason such as when the management method or the server configuration is changed. To delete unnecessary management files that may cause malfunction, refer to the following table and delete any of these files if they exist.

1.4.3 Notes on Using VSSHP on Windows Server 2012

1.4.3.1 Combined Use of VSSHP and Offloaded Data Transfer (ODX)

Using an Advanced Copy that uses VSSHP with Offloaded Data Transfer (ODX) is not available. When an ETERNUS DX Disk storage system model that supports the Offloaded Data Transfer function is used by a Windows Server 2012 server, Offloaded Data Transfer (ODX) may start an ODX session in the ETERNUS DX Disk storage system. An ODX session that is started by the Offloaded Data Transfer (ODX) cannot be used at the same time as an Advanced Copy session that uses VSSHP. Disable the Offloaded Data Transfer (ODX) by using one of the following methods:

• Disable Offloaded Data Transfer (ODX) on Windows Server 2012.

This operation is only valid for servers on which this operation is performed. For details on how to disable Offloaded Data Transfer (ODX), refer to the procedure that is provided by Microsoft:

http://technet.microsoft.com/en-us/library/jj200627.aspx

• Stop the Offloaded Data Transfer function on the ETERNUS DX Disk storage system.

This operation is valid for all the servers that use the ETERNUS DX Disk storage system. For details on how to stop the Offloaded Data Transfer function, refer to the ETERNUS DX Disk storage system manuals.

1.4.3.2 Use of Virtual Disks with the Storage Pool Function

Virtual disks that are created by using the Storage Pool function cannot be used by VSSHP as the copy source or copy destination.

Preparation

3.1 Advanced Copy License Registration

To use VSSHP, register an Advanced Copy license for the ETERNUS Disk storage system, and then specify settings for the Advanced Copy function such as the copy table size . Use ETERNUS Web GUI to register the Advanced Copy license and specify the settings for the Advanced Copy function. For more details on Advanced Copy license registration and Advanced Copy settings, refer to the user guide of the ETERNUS Disk storage system model.

Note that registration of the Advanced Copy license is not required for some models. Make sure to check whether license registration is necessary before registering a license.

3.2 Shadow Copy Destination Disk Creation

When the requester starts backup, VSSHP automatically selects a disk that has the same capacity as the source disk from the Shadow Copy destination disks registered in the backup disk pool management function to create a Shadow Copy of the source data. Therefore, a Shadow Copy destination disk must be created in advance.

VSSHP does not select a disk that has a different capacity from the source disk. For example, if the capacity of the Shadow Copy destination disk is larger than the capacity of the source disk, VSSHP will not select this disk.

The following examples show source disks to be backed up and Shadow Copy destinations to be registered in the backup disk pool management function.

Example 1

When two source disks (2GB) are backed up with one backup job, two 2GB volumes are created as Shadow Copy destinations and these volumes are registered in the backup disk pool management function.

When source disks A (2GB) and B (4GB) are backed up in the first backup, and source disks C (2GB) and D (2GB) are backed up in the second backup, Shadow Copy destination volumes A (2GB), B (4GB), and C (2GB) are created as Shadow Copy destinations and these volumes are registered in the backup disk pool management function.

In the first backup, Shadow Copy destinations A and B are automatically selected and used as Shadow Copy destinations. In the second backup, Shadow Copy destinations A and C are automatically selected and used as Shadow Copy destinations.

Example 3

Create the same number of Shadow Copy destination disks as the Shadow Copy sessions that are executed concurrently and register these disks in the backup disk pool management function. For example, when there are two partitions in a LUN and the shadow copies for these partitions are executed separately, two Shadow Copy destination disks are required.

3.2 Shadow Copy Destination Disk Creation

Example 4

Create the same number of Shadow Copy destination disks as the Shadow Copy sessions that are executed concurrently and register these disks in the backup disk pool management function. For example, when the backup of multiple VMs in a Hyper-V Cluster Shared Volume (CSV) is executed concurrently, the same number of Shadow Copy destination disks as VMs is required.

The following sections explain the types of disks to be used for Shadow Copy destinations that are supported by VSSHP, and the procedure for estimating disk capacity.

3.2.1 Selection of the Shadow Copy Destination Disk Type

Either a normal volume or an SDV may be used as the Shadow Copy destination. The following table shows the respective features of a "normal volume" and an "SDV". Choose a disk type according to your requirements.

Normal volume SDV

Copy type QuickOPC SnapOPC+

Features

For QuickOPC, a copy session starts for each copy as the first initial copy even if the copy source is same. This is why a full copy is performed for each copy session with QuickOPC.

• Suitable for backup of big databases

and file servers with a large amount of updates.

• A Shadow Copy destination must

have the same capacity as a source disk.

• Backup can be performed

regardless of the amount of updates.

ETERNUS VSS Hardware Provider 2.1 User’s Guide

• Suitable for backup of databases and

file servers with only a small amount of updates.

• Can operate with a capacity of the

Shadow Copy destination that is lower than that of the source disk.

• When the amount of updates exceeds

the SDV capacity, access to the Shadow Copy destination is lost. The required SDV capacity should be measured in advance.
