Cluster Backup
The need for cluster backup is essential for both business-critical and nonbusiness-
critical data. As data becomes an increasingly valued company asset, it needs to be
backed up on a regular basis. The process of backing up data will ensure that a
company’s assets are secure and available when a disaster strikes. The cluster itself
provides a high degree of application availability but does not prevent a user from
deleting or corrupting a file or set of files. Backing up the data of a cluster will
increase the overall level of data availability.
There are several methods for backing up clustered systems, including:
• Attaching both cluster nodes to a single tape backup device, such as the
Fibre Channel-based StorageWorks Enterprise Backup Solution by Compaq
• Attaching two tape backup subsystems, where one tape backup subsystem is
attached to each cluster node
• Establishing a separate backup server that uses the standard public client LAN as
the backup path
Tape backup software varies in its level of cluster-aware integration and operation.
Contact your tape backup software vendor for more information about their specific
cluster implementation and support.
