Back up and restore your Amazon EKS cluster resources using Velero

This article provides a comprehensive tutorial on backing up and restoring Amazon EKS cluster resources using Velero, an open-source Kubernetes backup tool.

• Velero backs up Kubernetes objects to Amazon S3 and persistent volumes as EBS snapshots
• Supports cross-cluster restores, namespace-level granularity, and portability across distributions
• Configure least-privilege IAM roles using EKS Pod Identity for secure access
• Replace default cluster-admin permissions with scoped ClusterRole for security
• Deploy sample stateful application, create backup, restore to different namespace
• Install snapshot-controller add-on for EBS snapshot support
• Define VolumeSnapshotClass for CSI driver integration with Amazon EBS
• Backup includes deployments, pods, PVCs, services, configmaps, and secrets
• Namespace mapping enables restoring to different namespaces within same cluster
• Verify restored data matches original persistent volume contents

This tutorial demonstrates production-ready Velero setup on EKS with security best practices, enabling reliable disaster recovery and cluster resource portability.
