Chapter 7, Extended Frozen Image Services (Array Integration Option) 93

Overview

This section describes the frozen image methods provided in the Extended Frozen Image

Services option, explains the need for data mirroring, and introduces terms used in this

chapter.

The Frozen Image Methods

The “Extended Frozen Image Services” option allows you to configure mirror-type frozen

image backups. The client data to back up must reside on one of the following types of

disk arrays: EMC Symmetrix, Hitachi Data Systems, or Hewlett Packard XP. To make the

frozen image, you configure NetBackup to use one of the following methods:

◆ TimeFinder

The TimeFinder frozen image method is for making mirror frozen images on EMC

Symmetrix disk arrays with TimeFinder Symapi (with or without VERITAS Volume

Manager 3.1 or later). Supports UFS and VxFS file systems, logical volumes, and raw

partitions.

◆ ShadowImage

The ShadowImage frozen image method is for making mirror frozen images on

Hitachi Data Systems (HDS) disk arrays with ShadowImage (HOMRCF). Supports

UFS and VxFS file systems, logical volumes, and raw partitions.

◆ BusinessCopy

The BusinessCopy frozen image method is for making mirror frozen images on HP

XP series disk arrays with BusinessCopy Services. Supports UFS and VxFS file

systems, logical volumes, and raw partitions.

Note Select Timefinder, ShadowImage, or BusinessCopy according to the vendor-type of

disk array that contains the backup data. If the frozen image method does not match

the vendor-type of the array, the backup will fail.
