 |**Replace existing**    |   You can restore a disk and use it to replace a disk on the existing VM. Azure Backup takes a snapshot of the existing VM before replacing the disk and stores it in the staging location you specify. Existing disks connected to the VM are replaced with the selected restore point. The current VM must exist. You can't use this option if the VM is deleted.      |
 |**Cross region (secondary region)**   |   Cross region restore can be used to restore Azure VMs in the secondary region, which is an Azure paired region.<br> This feature is available for the following options:<br> <li> Create a VM <li> Restore Disks<br> We don't currently support the Replace existing disks option. |
 | **Cross Subscription Restore** | Backup Admins and App admins can perform the restore operation on secondary regions. <br> Cross Subscription Restore: <br><br> - Allows you to restore Azure Virtual Machines or disks to a different subscription within the same tenant as the source subscription. As per the Azure role-based access control capabilities from restore points. <br> - Allowed only if the Cross Subscription Restore property is enabled for your Recovery Services vault. <br> - Works with Cross Region Restore and Cross Zonal Restore. <br> - You can trigger Cross Subscription Restore for managed virtual machines only. <br> - Cross Subscription Restore is supported for Restore with Managed System Identities (MSI). <br> - It's unsupported for snapshots tier recovery points. <br> - It's unsupported for unmanaged VMs and VMs encrypted with Advanced Digital Encryption (ADE). |
-| **Cross Zonal Restore** | Allows you to restore Azure Virtual Machines or disks pinned to any zone to different available zones (as per the Azure Role-based access control capabilities) from restore points. When you select a zone to restore, it selects the logical zone (and not the physical zone) as per the Azure subscription you use to restore to. <br> - You can trigger Cross Zonal Restore for managed virtual machines only. <br> - Cross Zonal Restore is supported for Restore with Managed System Identities (MSI). <br> - Cross Zonal Restore supports restore of an Azure zone pinned/non-zone pinned VM from a vault with Zonal-redundant storage (ZRS) enabled. Learn how to set Storage Redundancy. <br> - You can only use Cross Zonal Restore to restore a VM pinned to an Azure zone from a vault with Cross Region Restore (CRR) under these conditions: The secondary region supports zones, or Zone Redundant Storage (ZRS) is enabled. <br> - Cross Zonal Restore is supported from secondary regions. <br> - It's unsupported from snapshots restore point. <br> - It's unsupported for Encrypted Azure VMs. |

Using this capability, you can selectively back up a subset of the data disks that are attached to your VM. Then, you can restore a subset of the disks that are available in a recovery point, both from instant restore and vault tier. <br><br>  Selective disk backup is useful when you: <br><br> - Manage critical data in a subset of the VM disks. <br> - Use database backup solutions and want to back up only their OS disk to reduce cost. |
