High availability of the NetBackup master service
The NetBackup master service manages backups, archives, and restores. The master service is responsible for media and device selection for NetBackup. Typically, the master service contains the NetBackup catalog. The catalog contains the internal databases that contain information about NetBackup backups and configuration.
NetBackup Flex Scale is a clustered solution and hence, it ensures availability of the NetBackup master service. The master service is guarded against failures that include but are not limited to the following scenarios:
Failure of the NIC where the NetBackup master service IP address is hosted
Failure of the node where the NetBackup master service is running
Failure of the NetBackup master 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 master 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 master service is offline.
If the master service goes offline, it is failed over and comes online on another cluster node. For details on the behavior of the NetBackup master service in clustered environments and handling the jobs, see the General notes on clustered master service administration chapter in the Veritas NetBackup™ Clustered master service Administrator's Guide on SORT.
