 # Customer intent: As a cloud architect, I want to understand the limitations and requirements of Ultra Disks so that I can evaluate their suitability for my virtual machine deployments and ensure compliance with application needs and infrastructure capabilities.
@@ -16,10 +16,8 @@ The following list contains Ultra Disk's limitations:
 - Ultra Disks don't support availability sets.
 - Existing disks currently can't change their type to an Ultra Disk. They must be [migrated](/azure/virtual-machines/disks-convert-types?tabs=azure-powershell#migrate-to-premium-ssd-v2-or-ultra-disk-using-snapshots).
 - (Preview) You can encrypt Ultra Disks with customer-managed keys using Azure Key Vaults stored in a different Microsoft Entra ID tenant.
-- Azure Site Recovery for VMs with Ultra Disks is currently in [Public Preview](/azure/site-recovery/azure-to-azure-support-matrix).
 - Ultra Disks don't support disk caching.
 - Snapshots are supported with [other limitations](/azure/virtual-machines/disks-incremental-snapshots?tabs=azure-powershell#incremental-snapshots-of-premium-ssd-v2-and-ultra-disks).
-- Azure Backup support for VMs with Ultra Disks is [generally available](/azure/backup/backup-support-matrix-iaas#vm-storage-support). Azure Backup has limitations when using Ultra Disks, see [VM storage support](/azure/backup/backup-support-matrix-iaas#vm-storage-support) for details.
 
 Ultra Disks support a 4k physical sector size by default but also supports a 512E sector size. Most applications are compatible with 4k sector sizes, but some require 512-byte sector sizes. Oracle Database, for example, requires release 12.2 or later in order to support 4k native disks. For older versions of Oracle DB, 512-byte sector size is required.
