 3. If you're using [Enhanced policy](backup-azure-vms-enhanced-policy.md), you can use this solution to exclude unsupported disks (Ultra Disks, Shared Disks) and configure a VM for backup. 
 
-Using PowerShell, Azure CLI, or Azure portal, you can configure selective disk backup of the Azure VM. Using a script, you can include or exclude data disks using their LUN numbers. The ability to configure selective disks backup through the Azure portal is limited to the **Backup OS Disk only** for the Standard policy, but can be configured for all data disks. So, you can configure backup of your Azure VM with OS disk, and exclude all the data disks attached to it.

 Azure virtual machine backup follows the existing pricing model, explained in detail [here](https://azure.microsoft.com/pricing/details/backup/).
 
-- If you're using Standard policy, **Protected Instance (PI) cost** is calculated for the OS disk only if you choose to back up using the **OS Disk only** option.  If you configure backup and select at least one data disk, the PI cost will be calculated for all the disks attached to the VM. **Backup storage cost** is calculated based on only the included disks and so you get to save on the storage cost. **Snapshot cost** is always calculated for all the disks in the VM (both the included and excluded disks).

-- If you're using Enhanced policy, **Protected Instance (PI)** cost, snapshot cost, and vault tier storage cost are all calculated based on the disks that you've included for backup.
