Software Requirements

You must satisfy the following software requirements to install Arcserve Backup as a CLUSTERPRO/ExpressCluster-aware application:

Install Arcserve Backup on a switched disk of the cluster with the same drive letter assigned to the volume from all nodes for Active/Passive job failover capability.
Install the same Arcserve Backup components on all nodes. You must configure each of these components in the same way.
Use the same Arcserve Backup Device Group Name for the same devices in the Arcserve Backup configuration on each node of the cluster. To ensure this, use the default Device Group Names assigned by Arcserve Backup when you use Device Configuration.
Use the same Arcserve Backup system accounts for all Arcserve Backup servers installed on each of the cluster nodes.
Ensure that the Cluster nodes are in the same domain during the installation.
