CLUSTER USER GUIDE
Prepare EraBackup Kubernetes agent policies, PVC/Pod selection and node/control-plane methods for your distribution; plan catalog and isolated restore acceptance together.
BEFORE YOU BEGIN
Kubernetes Backup exposes PVC, ETCD, KUBELET, ETCKUBERNETES and CLUSTER options. These labels do not establish whole-cluster recovery support across releases. The OpenShift VM/database workflow is separate and does not automatically apply to generic Kubernetes or Rancher.
Screenshots were captured from the actual lab interface on 16 October 2026. The interface is in English; explanations follow your selected language. Resource names, dates and settings are examples; use values for your own environment.
Lab note: the Kubernetes agent returned a read timeout. The existing test job shows Not Yet Backup; no usable point or restore target screen was captured. No policy was saved and no backup/restore was started.
Inventory Deployment/StatefulSet, Service, ConfigMap, PVC and external database dependencies. Keep Secret values out of output. Separate ephemeral Pod filesystems from PVC data; a Pod name or manifest list is not a complete application backup.
Protected resources and the recovery objective are documented.
Verify the correct kubeconfig context, namespace access and required agent connection. If CSI snapshots are used, separately check driver, snapshot controller and VolumeSnapshotClass compatibility; this does not imply every EraBackup method uses snapshots. A snapshot alone does not establish a repository copy.
kubectl config current-context
kubectl -n <NAMESPACE> get pods,pvc
kubectl get storageclassAccess and prerequisites for the selected data path are understood.
Open Home → Policies → Agent Policy → Create Agent Policy. Select the correct Linux Agent, Policy Name and Storage. Choose Kubernetes Backup as Policy Type. Treat an agent connection error as a form-only inspection; a registered node name is not live cluster access.
A source/repository draft is prepared.
Evaluate the appropriate PVC method in Kubernetes Backup Methods for an initial workload test; it requires the relevant Pod selection in Clients. ETCD, KUBELET and ETCKUBERNETES address node/control-plane scope. CLUSTER may disable individual selections; this behavior is not a full disaster recovery guarantee. Select only the approved protection method.
The method and required source selection are explicit.
For a PVC containing a database distinguish crash consistency from application consistency; validate the matching quiesce/native database plan. Set retention and scheduling against RPO and repository capacity. ETCD configuration may offer KUBECTL/RKE2; assess suitability for the installed distribution separately.
Consistency and retention plans match the selected method.
After validating source selection and access, review the summary and save the approved test policy. Use the appropriate Full action provided by the release. Compare task, repository object, method, namespace/Pod and time. A notification or Last Backup alone is not data acceptance.
Output and catalog records match the source.
Validate a test file or critical application query on an isolated target. Record the recovery order for PVC data, manifests and external services. Document namespace, storage, versions, backup ID and duration. An application test does not establish etcd/control-plane recovery acceptance.
Workload recovery acceptance is documented.
COMMON QUESTIONS
No. A menu label does not replace distribution/release, data-path and actual isolated restore acceptance.
