Kubernetes Backup & Restore: Velero + MinIO Complete Guide

Kubernetes environments demand reliable backups to prevent data loss from misconfigurations or disasters. This step-by-step tutorial shows how to set up Velero with a local MinIO backend for namespace backups and restores using Helm on Minikube or any cluster. Why Velero with MinIO? Velero backs up Kubernetes resources like deployments, services, and volumes via the API server, storing them in object storage like MinIO (S3-compatible). It's the leading open-source tool for disaster recovery, cluster migration, and scheduled backups in 2026 production setups. MinIO provides a lightweight, self-hosted S3 alternative ideal for development, air-gapped clusters, or cost-sensitive teams—avoiding cloud vendor lock-in. Pro Tip: Always test restores quarterly; untested backups fail 70% of the time in real incidents. Prerequisites Ensure these are ready before starting: Docker and Docker Compose installed. Kubernetes cluster (e.g., Minikube v1.33+). kubectl configured. Helm v3+. Update MinIO IP
