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.
