Backups of VMs in a Cluster-Aware Environment Fail

Valid on Windows Hyper-V systems.

Symptom

Backups of VMs in a cluster-aware environment fail.

Solution

The following diagram illustrates VMs installed in a cluster-aware environment:

In an ideal scenario, virtual cluster node V1 directs network traffic to the active node (N1). When failover occurs, virtual cluster node V1 directs the network traffic to the passive node (N2), and all of the VMs in the active node (N1) move to the passive node (N2).

If Arcserve Backup backs up the active node (N1) after failover occurs, the backup will fail because Arcserve Backup cannot locate the VMs in the active node (N1).

To remedy this problem, do the following:

• Submit backups by specifying the entire Hyper-V node, which includes the active node and the passive node, rather than the individual VMs that are configured in the Hyper-V node.
• Ensure that Arcserve Backup executes the auto-population process before Arcserve Backup backs up the clustered nodes.

Note: Arcserve Backup does not support backing up VMs that are configured with virtual node names. For example, If you submit a backup Job using the virtual node V1 as the backup proxy system, Arcserve Backup will back up data using the active node (N1 or N2), as the backup proxy system.
