+## Azure Kubernetes Service cluster backup (preview)
+
+Azure Kubernetes Service (AKS) backup is a simple, cloud-native process to back up and restore the containerized applications and data running in AKS clusters. You can configure scheduled backup for both cluster state and application data (persistent volumes - CSI driver based Azure Disks). 
+
+The solution provides granular control to choose a specific namespace or an entire cluster to back up or restore with the ability to store backups locally in a blob container and as disk snapshots. With AKS backup, you can unlock end-to-end scenarios - operational recovery, cloning test or developer environments, or cluster upgrade scenarios. 
+
+AKS backup integrates with Backup center (with other backup management capabilities) to provide a single pane of glass that helps you govern, monitor, operate, and analyze backups at scale.
+ 
+For more information, see [Overview of AKS backup (preview)](azure-kubernetes-service-cluster-backup-concept.md).

 ## Multi-user authorization using Resource Guard for Backup vault (in preview)
 
 Azure Backup now supports multi-user authorization (MUA) that allows you to add an additional layer of protection to critical operations on your Backup vaults. For MUA, Azure Backup uses the Azure resource, Resource Guard, to ensure critical operations are performed only with applicable authorization.
