Introduction to NetBackup 53xx high availability solution
Starting with NetBackup Appliance release 3.1, Veritas offers a high availability (HA) solution for 53xx appliances. The HA solution helps to ensure system throughput and operational availability for data protection operations.
The 53xx high availability solution is a dual-node solution that provides the following benefits:
Two 53xx compute nodes (a node and a partner node) that operate in an active/active mode through an HA configuration.
The two nodes efficiently share the storage workload.
All stored data is available and accessible through either node.
All system jobs can be run on one node while its partner node is serviced or upgraded.
Automatic failover and job retry for a single-node failure.
Existing systems can be converted for an HA solution.
