Set up a process server in Azure for failback

After you fail over VMware VMs or physical servers to Azure using Site Recovery, you can fail them back to the on-premises site when it's up and running again. In order to fail back, you need to set up a temporary process server in Azure, to handle replication from Azure to on-premises. You can delete this VM after failback is complete.

Before you start

Learn more about the reprotection and failback process.

This article assumes that

  1. A Site to Site VPN or an Express Route connection between your on-premises network and the Azure Virtual Network has already been established.
  2. Your user account has permissions to create a new virtual machine in the Azure Subscription that the virtual machines have been failed over into.
  3. Your subscription has a minimum of 4 Cores available to spin up a new Process Server virtual machine.
  4. You have the Configuration Server Passphrase available.

Tip

Ensure that you are able to connect port 443 of the Configuration Server (running on-premises) from the Azure Virtual Network that the virtual machines have been failed over into.

Deploy a process server in Azure

  1. In the vault > Site Recovery Infrastructure> Manage > Configuration Servers, select the configuration server.
  2. In the server page, click + Process server
  3. In Add process server page, and select to deploy the process server in Azure.
  4. Specify the Azure settings, including the subscription used for failover, a resource group, the Azure region used for failover, and the virtual network in which the Azure VMs are located. If you used multiple Azure networks, you need a process server in each one.

    Add process server gallery item

  5. In Server name, User name, and Password, specify a name for the process server, and credentials that will be assigned Admin permissions on the server.

  6. Specify a storage account to be used for the server VM disks, the subnet in which the process server VM will be located, and the server IP address that will be assigned when the VM starts.
  7. Click OK button to start deploying the process server VM.

Registering the process server (running in Azure) to a Configuration Server (running on-premises)

After the process server VM is up and running, you need to register it with the on-premises configuration server, as follows:

  • Connect to the Process Server virtual machine using Remote Desktop Connection.
  • You can launch the cspsconfigtool.exe by clicking on the shortcut available on the desktop. (The tool will be automatically launched if this the first time you are logging into the process sever).

    • Configuration Server's fully qualified name (FQDN) or IP Address
    • Port on which the Configuration server is listening on. The value should be 443
    • Connection Passphrase to connect to the configuration server.
    • Data Transfer port to be configured for this Process Server. Leave the default value as is unless you have changed it to a different port number in your environment.

      Register Process Server

  • Click the save button to save the configuration and register the Process Server.
