46 Strategies for Backup and Recovery

Choosing a Backup Method

There are many ways to backup cluster data. For example, you can follow the

steps in the Microsoft TechNet article Backing up and restoring server clusters

to backup cluster data using the Microsoft Backup utility, NTBackup. For

more information, see Microsoft documentation.

Alternately, to backup cluster data, you can use a backup application from the

vendor of your choice. Consider the following when choosing a backup

application:

• Verify that the backup application is capable of acting as a VSS requestor,

so you can use the VSS backup feature. Backup applications that support

VSS and can be used as a VSS requestor include CommVault

Galaxy

Backup & Recovery.

• The Cluster backup software should be

cluster aware

. The software should

use cluster APIs and be able to deal with the failover of a disk resource

during the backup process.

• Ensure that your backup application is compatible with the version of the

Windows operating system installed on the cluster nodes. Another method

of protecting Windows Unified Data Storage Server 2003 data is by using a

near-continuous backup and archiving solution that unifies data

protection, disaster recovery, and archiving. This type of solution provides

immediate recovery, file, e-mail, or, database storage optimization, instant

user access, and regulatory compliance in a Windows Unified Data Storage

Server 2003 environment. You can maintain copies of the Windows

Unified Data Storage Server 2003 data on a separate server and

continuously update these copies as the data changes. If a catastrophic

failure occurs, the data loss is zero or at most a few minutes.

Backup applications that support near-continuous backup and archiving fall

under different categories and include Microsoft Data Protection Manager

(DPM). DPM is a server software application that optimizes disk-based

backup and recovery. It provides continuous data protection for file servers.
