Error during backup: Namespace has been marked for deletion
This error appears when the namespace that you tried to backup was deleted from the Kubernetes cluster. NetBackup asset service also deletes that asset from the asset database. But if there was a backup available for that namespace then the asset service does not delete the asset but rather marks it as DELETED. In this case, we don't want to take the backup of such assets or namespaces.
Recommended action: Verify if the namespace exists on the cluster.
