 ## Limitations
 
-- Azure Disk Backup is supported for Azure Managed Disks, including shared disks (Shared premium SSDs). Unmanaged disks aren't supported. Currently this solution doesn't support Ultra-disks, including shared ultra-disks, because of lack of snapshot capability.

 - Azure Disk Backup supports backup of Write Accelerator disk. However, during restore the disk would be restored as a normal disk. Write Accelerated cache can be enabled on the disk after mounting it to a VM.
 
 - Azure Backup provides operational (snapshot) tier backup of Azure managed disks with support for multiple backups per day. The backups aren't copied to the backup vault.
 
 - Currently, the Original-Location Recovery (OLR) option to restore by replacing existing source disks from where the backups were taken isn't supported. You can restore from recovery point to create a new disk either in the same resource group as that of the source disk from where the backups were taken or in any other resource group. This is known as Alternate-Location Recovery (ALR).
 
-- Azure Backup for Managed Disks uses incremental snapshots, which are limited to 200 snapshots per disk. To allow you to take on-demand backup aside from scheduled backups, Backup policy limits the total backups to 180. Learn more about [incremental snapshot](../virtual-machines/disks-incremental-snapshots.md#restrictions) for managed disks.
+- Azure Backup for Managed Disks uses incremental snapshots, which are limited to 500 snapshots per disk. To allow you to take on-demand backup aside from scheduled backups, Backup policy limits the total backups to 480. Learn more about [incremental snapshot](../virtual-machines/disks-incremental-snapshots.md#restrictions) for managed disks.
 
 - Azure [subscription and service limits](../azure-resource-manager/management/azure-subscription-service-limits.md#virtual-machine-disk-limits) apply to the total number of disk snapshots per region per subscription.
