NetBackup charges only for the persistent volumes snapped as part of snapshot operation.

NetBackup considers persistent volumes contained within the namespace for calculation when you perform snapshot for a namespace.

Kubernetes does not publish the actual allocated or used blocks within a volume. Hence, for license usage reporting, NetBackup considers the provisioned size.

The client name reported under licensing reports is of the form: <Cluster Name>:<Namespace Name>. If no persistent volumes were snapped as part of backup, and for the policy and client combination not a single backup image exists with non-zero size reported, nbdeployutil adds a comment "size unavailable". In this case, no charges are levied.
