Production disappears at 3 AM: a failed disk, a bad script, a compromised account. Your backups are now the only way back, if they actually work.
You'll see how Velero brings back Kubernetes workloads and their data, what it quietly leaves out, and how CSI snapshots and file-system backups keep persistent volumes safe. To cover the hosts and NAS shares, we'll introduce restic, which offers encrypted, deduplicated backups to any storage, with append-only repositories that ransomware and mistakes can't wipe.
By the end, you'll have a 3-2-1 strategy, RPO and RTO targets you can actually meet, and automated restore drills that prove your backups work. An untested backup is just a hope!
