About Backup Exec and server clusters

In a server cluster, Backup Exec can protect data on local disks and shared disks, as well as protect Microsoft SQL and Exchange databases that are configured as virtual server applications; that is, they contain an IP address resource, a Network Name resource, and are displayed on the network with a unique server name (the virtual server name). Clustered servers provide high availability of applications and data to users. In a clustered server, several servers (called nodes) are linked in a network, and run cluster software that allows each node access to the shared disks. If a node becomes unavailable, cluster resources migrate to an available node (called failover). The shared disks and the virtual server are kept available. During failover, users experience only a short interruption in service.

Note:

For offhost backups that use the hardware provider in a Microsoft Cluster Server (MSCS) or Veritas Cluster Services environment, the media server and the remote computer must be in different cluster groups. The cluster applications cannot support devices' logical unit numbers (LUNs) that have duplicate signatures and partition layouts, therefore, the snapshots containing the LUNs must be transported to a host, or remote computer, that is outside the cluster.
