High availability of the NetBackup primary service
The NetBackup primary service manages backups, archives, and restores. The primary service is responsible for media and device selection for NetBackup. Typically, the primary service contains the NetBackup catalog. The catalog contains the internal databases that contain information about NetBackup backups and configuration.
Note:
This section is not applicable if you deploy a cluster with only media servers.
NetBackup Flex Scale is a clustered solution and hence, it ensures availability of the NetBackup primary service. The primary service is guarded against failures that include but are not limited to the following scenarios:
Failure of the NIC where the NetBackup primary service IP address is hosted
Failure of the node where the NetBackup primary service is running
Failure of the NetBackup primary service process
Failure of the docker container
Failure of the docker service
The file system that is used as the NetBackup catalog file system is a three-way mirrored file system.
The icon in the top navigation bar shows the status of the current events. The status of the health of the primary service is displayed.
The bell icon in the top navigation bar shows the status of current alerts and alerts that were recently completed. An AutoSupport alert is raised if the primary service is offline.
If the primary service goes offline, it is failed over and comes online on another cluster node. For details on the behavior of the NetBackup primary service in clustered environments and handling the jobs, see the General notes on clustered primary service administration chapter in the Veritas NetBackup™ Clustered primary service Administrator's Guide on SORT.
