Step-by-Step A Comprehensive Tutorial: How to Back Up and Restore Kubernetes Cluster with Velero

We back up the Kubernetes cluster for disaster recovery, data migration, and data protection. A comprehensive backup and restore strategy is essential, to guarantee the resilience and reliability of your apps and data in Kubernetes clusters. As the number of microservices in K8s increases, a centralized backup mechanism becomes more critical. There are several approaches to back up and restore a Kubernetes cluster. In this article, I will use Velero to back up and restore Amazon EKS clusters. To do this, I’ll create an IAM role for Velero, and then download Velero and install it on the Amazon EKS cluster. Then, I’ll create a storage location using an Amazon S3 bucket.
Finally, I’ll back up my Kubernetes resources in the Kubernetes cluster using the Velero CLI commands, and restore my Kubernetes resources from the backup I made.
Thus, in this article, we will learn how to quickly recover from failures and disaster events and how to perform seamless migrations for apps and cluster resources in Amazon EKS.
We will do these practically step by step in this article.
