**Replace existing** | You can restore a disk, and use it to replace a disk on the existing VM.<br/><br/> The current VM must exist. If it's been deleted, this option can't be used.<br/><br/> 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.<br/><br/> The snapshot is copied to the vault, and retained in accordance with the retention policy. <br/><br/> After the replace disk operation, the original disk is retained in the resource group. You can choose to manually delete the original disks if they aren't needed. <br/><br/>Replace existing is supported for unencrypted managed VMs, including VMs [created using custom images](https://azure.microsoft.com/resources/videos/create-a-custom-virtual-machine-image-in-azure-resource-manager-with-powershell/). It's unsupported for classic VMs, unmanaged VMs, and [generalized VMs](../virtual-machines/windows/upload-generalized-managed.md).<br/><br/> If the restore point has more or less disks than the current VM, then the number of disks in the restore point will only reflect the VM configuration.<br><br> Replace existing is also supported for VMs with linked resources, like [user-assigned managed-identity](../active-directory/managed-identities-azure-resources/overview.md) or [Key Vault](../key-vault/general/overview.md).

**Cross Region (secondary region)** | Cross Region restore can be used to restore Azure VMs in the secondary region, which is an [Azure paired region](../availability-zones/cross-region-replication-azure.md).<br><br> You can restore all the Azure VMs for the selected recovery point if the backup is done in the secondary region.<br><br> During the backup, snapshots aren't replicated to the secondary region. Only the data stored in the vault is replicated. So secondary region restores are only [vault tier](about-azure-vm-restore.md#concepts) restores. The restore time for the secondary region will be almost the same as the vault tier restore time for the primary region. <br><br> This feature is available for the options below:<br><br> - [Create a VM](#create-a-vm) <br> - [Restore Disks](#restore-disks) <br><br> We don't currently support the [Replace existing disks](#replace-existing-disks) option.<br><br> Permissions<br> The restore operation on secondary region can be performed by Backup Admins and App admins.

**Cross Subscription Restore (preview)** | Allows you to restore Azure Virtual Machines or disks to any subscription (as per the Azure RBAC capabilities) from restore points. <br><br> You can trigger Cross Subscription Restore for managed virtual machines only. <br><br> Cross Subscription Restore is supported for [Restore with Managed System Identities (MSI)](backup-azure-arm-restore-vms.md#restore-vms-with-managed-identities). <br><br> It's unsupported for [snapshots](backup-azure-vms-introduction.md#snapshot-creation) and [secondary region](backup-azure-arm-restore-vms.md#restore-in-secondary-region) restores. <br><br> It's unsupported for [unmanaged VMs](#restoring-unmanaged-vms-and-disks-as-managed), [Encrypted Azure VMs](backup-azure-vms-introduction.md#encryption-of-azure-vm-backups) and [Trusted Launch VMs](backup-support-matrix-iaas.md#tvm-backup).

**Cross Zonal Restore (preview)** | Allows you to restore Azure Virtual Machines or disks pinned to any zone to different available zones (as per the Azure RBAC capabilities) from restore points. <br><br> You can trigger Cross Zonal Restore for managed virtual machines only. <br><br> Cross Zonal Restore is supported for [Restore with Managed System Identities (MSI)](#restore-vms-with-managed-identities). <br><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](backup-create-rs-vault.md#set-storage-redundancy). <br><br> It's supported to restore an Azure zone pinned VM only from a [vault with Cross Region Restore (CRR)](backup-create-rs-vault.md#set-storage-redundancy) (if the secondary region supports zones) or Zone Redundant Storage (ZRS) enabled. <br><br> Cross Zonal Restore is supported from [secondary regions](#restore-in-secondary-region). <br><br> It's unsupported from [snapshots](backup-azure-vms-introduction.md#snapshot-creation) restore point. <br><br> It's unsupported for [Encrypted Azure VMs](backup-azure-vms-introduction.md#encryption-of-azure-vm-backups) and [Trusted Launch VMs](backup-support-matrix-iaas.md#tvm-backup).
