Flexible Version Compatibility for Kubernetes Operator
The NetBackup Kubernetes operator no longer requires the NetBackup Primary Server and Media Server to be on the same NetBackup version. The operator can run on an earlier NetBackup version than the servers it connects to.
The Kubernetes operator can be:
Up to one NetBackup version older than the Media Server
Up to two NetBackup versions older than the Primary Server
The operator supports the features available in its own version. This supported configuration provides greater flexibility during phased upgrade scenarios.
During this upgrade model, existing Kubernetes policies continue to run backups. However, restore operations must be performed manually until the Kubernetes operator is upgraded.
