Starting with version 19.9, PowerProtect Data Manager uses structured customer resource definitions (CRDs) with Kubernetes to increase system security. PowerProtect Data Manager versions earlier than 19.9 used non-structural schemas that did not validate the consistent format of custom resources (CRs). When updating from older versions of PowerProtect Data Manager, the self-service recovery of the last backup copy taken before the update is not possible. To restore that backup, use the PowerProtect Data Manager user interface. There are important Kubernetes-specific factors to consider when updating PowerProtect Data Manager in a Kubernetes environment. For more information, see the Dell PowerProtect Data Manager Kubernetes User Guide.
