Software Requirements

To perform disaster recovery on clusters, you must meet the following software requirements:

Microsoft Windows 2003, Windows 2008, Windows Server 2008 R2, or Windows Server 2012 installed on all computers in the cluster.
A name resolution method, for example, Domain Naming System (DNS), Windows Internet Naming Service (WINS), or HOSTS.
A Terminal Server for administering remote clusters.
Arcserve Backup for Windows and the Disaster Recovery Option, if backup devices such as tape devices or tape library devices are attached to one or all cluster nodes. If no backup devices are attached to the cluster setting, the Client Agent for Windows should be installed on all cluster nodes that require data protection.
