How to Delete the Replication Appliance

Overview

The Azure Site Recovery replication appliance is a virtual machine that runs on-premises and replicates data from your on-premises servers to Azure for disaster recovery purposes. You can delete the appliance from the Azure portal, when you no longer need it.

This article provides a step-by-step guide for removing the Azure Site Recovery replication appliance from the Azure portal.

Before you begin

There are two ways to remove the replication appliance: delete and reset. If all the components of the appliance are in a healthy state and the appliance is still accessible, you're allowed to only reset the appliance. Resetting moves the appliance to its factory state, enabling it to be associated with any Recovery Service vault again.

If all the appliance components are in a critical state and there's no connectivity with the appliance, it can be deleted from the Azure portal. Before deleting the Recovery Services vault, you must also remove infrastructure to ensure that all the resources created in the background for replication and appliance registration are also removed. However, before you delete the Azure Site Recovery replication appliance, you must complete some preparatory steps to avoid errors.

Prerequisites

Before you delete the Azure Site Recovery replication appliance, ensure that you disable replication of all servers using the Azure Site Recovery replication appliance. To do this, go to Azure portal, select the Recovery Services vault > Replicated items blade. Select the servers you want to stop replicating, select Stop replication, and confirm the action.

Verify account permissions

If you just created your free Azure account, you're the administrator of your subscription and you have the permissions you need. If you're not the subscription administrator, work with the administrator to assign the permissions you need. To enable replication for a new virtual machine, you must have permission to:

  • Create a virtual machine in the selected resource group.
  • Create a virtual machine in the selected virtual network.
  • Write to an Azure storage account.
  • Write to an Azure managed disk.

To complete these tasks your account should be assigned the Virtual Machine Contributor built-in role. In addition, to manage Site Recovery operations in a vault, your account should be assigned the Site Recovery Contributor built-in role.

VMware account permissions

Task Role/Permissions Details
VM discovery At least a read-only user

Data Center object –> Propagate to Child Object, role=Read-only
User assigned at datacenter level, and has access to all the objects in the datacenter.

To restrict access, assign the No access role with the Propagate to child object, to the child objects (vSphere hosts, datastores, VMs and networks).
Full replication, failover, failback Create a role (Azure_Site_Recovery) with the required permissions, and then assign the role to a VMware user or group

Data Center object –> Propagate to Child Object, role=Azure_Site_Recovery

Datastore -> Allocate space, browse datastore, low-level file operations, remove file, update virtual machine files

Network -> Network assign

Resource -> Assign VM to resource pool, migrate powered off VM, migrate powered on VM

Tasks -> Create task, update task

Virtual machine -> Configuration

Virtual machine -> Interact -> answer question, device connection, configure CD media, configure floppy media, power off, power on, VMware tools install

Virtual machine -> Inventory -> Create, register, unregister

Virtual machine -> Provisioning -> Allow virtual machine download, allow virtual machine files upload

Virtual machine -> Snapshots -> Remove snapshots, Create snapshots
User assigned at datacenter level, and has access to all the objects in the datacenter.

To restrict access, assign the No access role with the Propagate to child object, to the child objects (vSphere hosts, datastores, VMs and networks).

Delete an unhealthy appliance

You can only delete the Azure Site Recovery replication appliance from the Azure portal if all components are in a critical state and the appliance is no longer accessible.

Important

The appliance must be unhealthy (in a critical state) for at least 30 minutes before it is eligible for deletion. If the appliance is healthy, you can only reset it. Ensure that you have disabled replication for all servers before deleting the appliance.

Note

Trigger the delete appliance from the portal after shutting down the VM. You shouldn't unregister any component from appliance to delete the appliance.

To delete an appliance, follow these steps:

  1. Sign in to the Azure portal.

  2. Go to the Recovery Services vault > Site Recovery infrastructure (under Manage), select Azure Site Recovery replication appliances under For VMware & Physical machines.

  3. For the Azure Site Recovery replication appliance you want to delete, select Delete from its menu.

  4. Confirm that no replicated items are associated with the replication appliance. If there are replicated items associated, a pop-up appears to block the appliance deletion.

  5. If no replicated items are associated with the appliance, a pop-up appears to inform you about the Microsoft Entra ID Apps that must be deleted. Note these App IDs and proceed with deletion.

Post delete appliance

After successfully deleting the Azure Site Recovery replication appliance, you can:

  • Free up resources used by the Azure Site Recovery replication appliance, such as the storage account, network interface, and public IP address.
  • Delete the Recovery Services vault if it is no longer needed.
  • Remove Microsoft Entra Apps with the Azure Site Recovery replication appliance. To do this, go to Azure portal > Microsoft Entra ID > App registrations under the Manage blade. Select the app that you should delete, and select Delete then confirm the action. You can learn the app names by following the steps here.

Reset a healthy appliance

You can only reset the Azure Site Recovery replication appliance if all components are in a healthy state. To reset the appliance, follow these steps:

  1. On the Azure portal, go to the appliance you want to reset. Ensure that no replicated items are associated with this appliance.
  2. On Microsoft Azure Appliance Configuration Manager, go to the Reset appliance section and select Reset.
  3. If no machines are associated with the appliance, the reset begins.
  4. Once completed successfully, ensure the following:
    • Open Services.msc and restart the service World Wide Web Publishing Service.
    • Clear the cache for Microsoft Edge or other browsers being used. Restart the browser after the cache cleanup. Learn more here.
    • Restart the machine.

Next steps

In this article, you learned how to delete the Azure Site Recovery replication appliance from the Azure portal. You can now free up the associated resources and delete the Recovery Services vault as needed.
