Question

A retail company runs a stateful application on Azure Kubernetes Service (AKS). The application stores data on Azure Disk-backed persistent volumes (PVs) via the Azure Disk CSI driver. The architecture team requires a backup and recovery solution that can protect both the Kubernetes cluster resources (deployments, config maps, namespaces) and the persistent volume data, and can restore the entire application to a new AKS cluster in the same region if the original cluster is accidentally deleted. The solution must minimize operational overhead and use a native Azure service. What should you recommend?

Accepted Answer

Enable Azure Backup for AKS (the AKS backup extension with Backup vault) to back up cluster resources and CSI-based persistent volume snapshots.

Answer

Configure Azure Backup on a Recovery Services vault to protect the AKS agent node VMs directly.

Answer

Take periodic Azure Managed Disk snapshots of the PV disks and store the Kubernetes YAML manifests in a Git repository.

Answer

Enable Azure Site Recovery replication for the AKS node pool virtual machine scale set to a secondary region.
