About NetBackup failover server data protection in a cluster
NetBackup protects the data in a cluster environment in several ways.
When NetBackup is installed as a failover server, a NetBackup server is installed on the cluster as a virtual server application. Then the server can fail over from one of the nodes to the other. The server is assigned a network name resource (the virtual server name), an IP address resource, and a disk resource. The NetBackup server fails over from one node to another if a failure occurs on the active node. This failover provides high availability of the NetBackup server itself.
When a failover occurs, the backup jobs that were running are rescheduled with the normal NetBackup retry logic for a failed backup. The NetBackup services are started on another node and the backup processing resumes.
The NetBackup failover master servers and media servers operate in an active or a passive failover configuration. The active node and the passive (or failover node) must be the same version of the master server.
The use of stand-alone media servers and NetBackup clients in a cluster is also briefly described later in this document.
