The models' case: The most mature Kubernetes-native data protection platform. The models' main caveat: Per-node enterprise licensing gets expensive at scale, and it's overkill (and over-priced) for a single small cluster or a hobbyist. The strongest alternative is Portworx Backup — Exceptional multi-cluster data protection for complex stateful workloads, providing granular cross-cluster cataloging, automated namespace mapping.
