On which cluster node(s) is the Avamar Windows File System client installed in a Microsoft Windows 2008 cluster?

To ensure high availability and consistent backup capability for clustered resources, the Dell Avamar client software must be installed on all nodes within the Microsoft Windows Failover Cluster. This allows the Avamar client, configured as a cluster resource, to function correctly regardless of which node is currently active. If a failover occurs, the Avamar services can start on the new active node and continue backup and restore operations without interruption.

B. Installing only on the active node would result in backup failures after a failover, as the new active node would lack the necessary software.

C. Installing only on passive nodes is illogical, as backups are performed against the active node that owns the resources.

D. Not installing the client on any node would make it impossible to back up the clustered file system resources.
