OADP (OpenShift API for Data Protection) is based on Velero and enables VM backup/restore via the KubeVirt plugin. This is the OpenShift-native way to back up or restore resources in the cluster. It does not provide a UI, but it is subscription-free and usable without a separate licence. The MinIO instance from PRE-11 is used as the S3 backend.

10Install velero CLI locally — for clearer backup/restore diagnosis (describe/logs) than raw oc log greps. No ConsoleCLIDownload/Route (unlike hcp) — official path is GitHub Releases or Homebrew
macOS:
brew install veleroLinux: download matching release from https://github.com/vmware-tanzu/velero/releases (check cluster version, Commands/YAML tab)
Verify:
velero version --client-only11Zero-install alternative (no local CLI): use
velero binary inside the running pod — see Commands/YAML tab
