Configure the Agent to Run on a Cluster

The following information does not apply to Exchange Server 2010/2013 systems. For the agent to properly perform document level backups on a cluster, the cluster resource type Arcserve Backup Exchange Server Agent Notifier must be registered and the resource instance type Arcserve Backup Exchange Server Agent Notifier must be created.

The binaries for the cluster resource type are CAExCluRes.dll and CAExCluResEX.dll. The installation procedure registers the cluster resource type and creates the cluster resources instance for you automatically when you install the agent on local nodes.

After the cluster resources are registered, you must specify a common location for the check point file. This location should be accessible from all possible nodes on which a virtual server can potentially run. This allows job continuation and incremental and differential jobs to properly execute even if they fail over to a different node. To set this destination, use one of the following registry keys:

Exchange Server 2003 Systems

HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\Arcserve Backup\ExchangeDocumentAgent\Parameters 
Value Name:       <VirtualServerName>_ChkPath
Value Type:       REG_SZ
Value Data:       <Path>

Exchange Server 2007 Systems

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ComputerAssociates\Arcserve Backup\ExchangeDocumentAgent\Parameters 
Value Name:       <VirtualServerName>_ChkPath
Value Type:       REG_SZ
Value Data:       <Path>

Example: Traditional Single Copy Cluster (SCC)

If virtual server EXVS1 is using drive g: as a disk resource to store data and virtual server EXVS2 is using drive h: as a disk resource to store data, add the following registry key on all nodes that are possible owners of these virtual servers.

Value Name:       EXVS1_ChkPath
Value Type:       REG_SZ
Value Data:       g:\CA\Temp

Value Name:       EXVS2_ChkPath
Value Type:       REG_SZ
Value Data:       h:\CA\Temp

Example: Exchange Server 2007 Cluster Continuous Replication (CCR)

Find a server with a shared device that can be accessed from all possible nodes of the virtual Exchange Server by the Exchange Server agent backup account user.

Note: It is recommended that you use the server hosting the Majority Node Set (MNS) quorum.

If the path on the shared device is \\ServerName\C$\CA\TEMP and the virtual server name is EXVS1, add the following registry key on all nodes that are possible owners of the virtual server.

Value Name:       EXVS1_ChkPath
Value Type:       REG_SZ
Value Data:       \\ServerName\C$\CA\Temp
