Backup & Restore of Lotus Domino Cluster using Data Protector

1. Abstract

This document describes steps necessary to implement support for Lotus Domino

Cluster with Data Protector. The versions of HP OpenView Storage Data Protector

addressed in this document are Data Protector A.05.10 and Data Protector

A.05.50.

2. Introduction

The Lotus Domino cluster components are installed with the Lotus Domino 6

Enterprise server or the Lotus Domino 6 Utility server. The components keep replica

Domino databases synchronized, and they communicate with each other to ensure

that the cluster is running efficiently and smoothly.

Unlike Operating System clusters (MSCS, MC/ServiceGuard cluster, and Veritas

cluster) the Lotus Domino cluster is an end application cluster. Which means that it

does not provide the cluster resources failover to a secondary cluster node in case

the primary cluster node gets unavailable, but just assures that a Lotus client can

access a replica database on another Domino server in case the Domino database

on the initial Domino server gets unavailable for connection. All the servers in a

Domino cluster continually communicate with each other to keep updated on the

status of each server and to keep database replicas synchronized.

The Domino cluster also lets the user to set limits for workload balancing, track the

availability of servers and databases, and add servers and databases to the cluster.

To take advantage of failover and workload balancing, databases and replicas are

distributed throughout the cluster. Replica of every database on every server is not

needed and the number of replicas created for a database depends on how busy

the database is and how important it is for users to have constant access to that

database.

3. Limitations and Assumptions

In the document we assume the following:

• Lotus Domino cluster is part of the Lotus Domino 6 Enterprise server or the Lotus

Domino 6 Utility server

• Lotus Domino 6 covers both the Lotus Domino 6.0.x and the Lotus Domino

6.5.x version and the Lotus Domino Cluster functionality is the same in both

versions
