Veritas NetBackup™ 53xx Appliance High Availability Reference Guide

Introduction to NetBackup 53xx high availability solution

Starting with the release version 3.1 of the NetBackup Appliance software, Veritas offers a high availability (HA) solution for NetBackup 53xx appliances. The HA solution guarantees the system throughput and operational availability for data protection operations.

The NetBackup 53xx high availability solution is a dual-node solution that provides the following benefits:

  • Two NetBackup 53xx compute nodes (a node and a partner node) 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 NetBackup jobs can be run on a node while its partner node is serviced or upgraded.

  • Automatic failover and job retry for a single-node failure.

  • Other than deploying new systems for the NetBackup 53xx high availability solution, the existing systems can also be converted for the HA solution.

The following diagram illustrates the internal communications in the NetBackup 53xx high availability solution:
