PowerProtect Data Manager protects Kubernetes workloads and ensures the data is consistent and highly available. PowerProtect Data Manager is a virtual appliance that is deployed on an ESXi host using OVA and is integrated with PowerProtect DD series appliances as protection target where backups are stored.
A Kubernetes cluster is group of a control-plane and worker nodes. The control-plane node manages the worker nodes, and it handles scheduling the pods across the nodes in the cluster. PowerProtect Data Manager integrates with Kubernetes cluster through Kubernetes APIs to perform the discovery. The CNDM is the component of PowerProtect Data Manager which communicates with the kube-apiserver of the cluster.
When the cluster is discovered, the cluster is added as PowerProtect Data Manager asset source and associated namespaces as assets are available to be protected. During the process of the discovery, PowerProtect Data Manager creates the following two namespaces in the cluster. The data is compressed and deduplicated at the source and sent to the target storage.
