 Azure Backup for AKS is a cloud-native, enterprise-ready, application-centric backup service that lets you quickly configure backup for AKS clusters.
 
 ## Before you start
 
+Before you configure vaulted backup for AKS cluster, ensure the following prerequisites are met:
+
 - Currently, AKS backup supports Azure Disk-based persistent volumes (enabled by CSI driver) only. The backups are stored only in operational datastore (in your tenant) and aren't moved to a vault. The Backup vault and AKS cluster should be in the same region.
 
 - AKS backup uses a blob container and a resource group to store the backups. The blob container has the AKS cluster resources stored in it, whereas the persistent volume snapshots are stored in the resource group. The AKS cluster and the storage locations must reside in the same region. Learn [how to create a blob container](../storage/blobs/storage-quickstart-blobs-portal.md#create-a-container).

-The policy template consists of a trigger criteria (which decides the factors to trigger the backup job) and a lifecycle (which decides when to delete, copy, or move the backups). In AKS backup, the default value for trigger is a scheduled hourly trigger is *every 4 hours (PT4H)* and retention of each backup is *seven days*.
