Commvault uses one or many Kubernetes access nodes to discover, back up, and restore your Kubernetes applications. Access nodes run backups and other operations.
You must have at least 1 access node for Kubernetes. In environments that require high availability for Kubernetes data management activities, having at least 2 access nodes is recommended. A single access node can protect multiple Kubernetes clusters. Commvault automatically load balances across available access nodes, and restarts data management activities that are interrupted when an access node becomes unavailable.
