About backing up database files in a cluster
Database applications are installed on a cluster as virtual servers. To protect the data for these virtual servers, install the appropriate NetBackup database agent on each node of the cluster. With NetBackup for Windows, database agents are installed along with NetBackup server and the NetBackup client.. Also create a backup policy for that database agent. When you configure a policy for the application or database in the cluster, always use the virtual server name of the application or database as the client name in the policy. For complete installation and configuration instructions for a particular database agent, see the NetBackup documentation for that agent.
