  • Test restores monthly — untested backups are not backups

What Needs Backing Up

Two things to back up: etcd (cluster state — all K8s objects) and Persistent Volumes (application data). etcd backup: etcdctl snapshot save <file>. For PVs: Velero (cross-cluster, scheduled backups with CSI snapshots) or cloud-native volume snapshots.

Key takeaways

  • etcd snapshot = full cluster state backup
  • Velero: backup PVs + K8s objects, restore to new cluster
  • Test restores monthly — untested backups are not backups
