 - Currently, an AKS backup supports only the backup of Azure disk-based persistent volumes (enabled by the CSI driver). The supported Azure Disk SKUs are Standard HDD, Standard SSD, and Premium SSD. The disks belonging to Premium SSD v2 and Ultra Disk SKU aren't supported. Both static and dynamically provisioned volumes are supported. For backup of static disks, the persistent volumes specification should have the *storage class* defined in the **YAML** file, otherwise such persistent volumes are skipped from the backup operation.
 
-- Azure Files shares and Azure Blob Storage persistent volumes are not supported by AKS backup due to lack of CSI Driver-based snapshotting capability. If you're using said persistent volumes in your AKS clusters, you can configure backups for them via the Azure Backup solutions. For more information, see [Azure file share backup](azure-file-share-backup-overview.md) and [Azure Blob Storage backup](blob-backup-overview.md).

 - For successful backup and restore operations, the Backup vault's managed identity requires role assignments.
