By default the Agent for Microsoft Exchange Server is configured to use the Cluster primary (public) IP address. This document provides steps to configure Exchange 2007 CCR database level backups from the replica node via a specific IP in cluster configurations with multiple IP addresses.
IMPORTANT: This article contains information about modifying the registry.
Before you modify the registry, make sure to create a back up of the registry and ensure that you understand how to restore the registry if a problem may occur.
For information about how to back up, restore, and edit the registry, please review the relevant Microsoft Knowledge Base articles on support.microsoft.com.
The solution is to add a Replica Node IP address for each of the physical nodes of the CCR cluster in the Exchange DB Agent Parameters registry key. This will force ARCserve Backup to use the IP that is defined when doing a CCR replica backup when the given node is the active node.
For example; the Cluster Virtual name 'ExchCCRCluster' has 2 physical nodes; 'ExchangeNodeA' and ExchangeNodeB'. Add a registry value to each of the physical nodes' registries:
HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\CA ARCServe Backup\ExchangeDBAgent\Parameters
Value Type: REG_SZ;
Value Name: ReplicaNodeIP
Value Data: < IP >
The Value Data should be configured with the replica node's backup IP address.
- ExchangeNodeA with designated backup IP: 10.10.10.1. Add registry Name 'ReplicaNodeIP', then set Data to '10.10.10.2'.
- ExchangeNodeB with designated backup IP: 10.10.10.2. Add registry Name 'ReplicaNodeIP', then set Data to '10.10.10.1'.
The CA ARCserve Universal Agent service needs to be restarted for the change to take effect.
