## Overview

This repository provides two interactive Bash scripts for backing up an AKS cluster with Velero and restoring or migrating that backup to another AKS cluster. The documented workflow provisions shared Azure blob storage and source-cluster Velero, then configures Velero on the target cluster to access the backup. The README also describes disk-snapshot migration for cross-subscription restores. Source excerpts were unavailable, so relationships below reflect README documentation only.

Main entry points: [`source-aks-cluster.sh`](https://github.com/mutazn/backup-and-restore-aks-cluster-using-velero/blob/main/source-aks-cluster.sh) (Source setup script), [`target-aks-cluster.sh`](https://github.com/mutazn/backup-and-restore-aks-cluster-using-velero/blob/main/target-aks-cluster.sh) (Target setup script)
