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.

User backups

User backups that are run on individual nodes of the cluster generally run as a backup of the node, not the NetBackup virtual server. You may find it easier to use scheduled backups rather than user backups to protect the data in the cluster.

NetBackup client in a cluster

You may choose to install only the NetBackup client in a cluster. In this configuration, you can back up the data from the cluster across the network to a separate NetBackup server. In this situation the NetBackup-specific configuration tasks for tape devices, media, and so on, are separate from the setup and maintenance of the cluster itself. However, the NetBackup client itself cannot fail over.

To install the NetBackup client on a WSFC, VCS, SunCluster , Service Guard cluster, or HACMP cluster

The NetBackup client is installed on a cluster as it is in a non-clustered environment. Refer to the Veritas NetBackup Installation Guide for information on how to install the NetBackup client. On Windows systems, you may have problems with name resolution when you try to back up data on the cluster. (This data can be either local data or shared data.) Consider setting the Required Network Interface parameter for each client to the fully qualified name of the node where the NetBackup client is installed.
