How to enable replication for virtual machines

Last published : Apr 02, 2026
You can enable replication for virtual machines from the Backup Exec console. Replication is a continuous backup of your virtual machine in Azure cloud. When disaster occurs, you can failover to the target virtual machine.
If you have logged on to Microsoft Azure as a Global Administrator, an Owner, or a User Access Administrator, you can enable replication in Backup Exec.
Refer to the Required permissions section in the Microsoft documentation for more information:
To enable replication in Backup Exec, you must first create replication policies in the Azure portal. When you prepare the infrastructure for your Recovery Services Vault, create the replication policies for your virtual machines.
You can enable replication for VMware and Hyper-V virtual machines.
To enable replication for virtual machines
  1. On the Instant Cloud Recovery tab, right-click the virtual machine for which you want to enable replication and click Enable Replication.
The Enable Replication dialog box is displayed.
Note: You cannot enable replication for a virtual machine that has validation errors.
  1. Select the VMware or Hyper-V parameters.
    Virtual Machine Name VMware and Hyper-V Displays the name of the VMware or Hyper-V virtual machine for which you want to enable replication.
    Target Machine Name VMware and Hyper-V Type the name of the target VMware or Hyper-V virtual machine.
    The target machine name must meet the following requirements:
    - The target machine name cannot be empty.
    - The target machine name length cannot exceed 63 characters.
    - The target machine name must start with a letter and can contain only letters, numbers, and hyphens.
    Operating System Hyper-V Select the operating system of the Hyper-V virtual machine. The target virtual machine in Azure cloud is created with the same operating system.
    Process Server VMware Select the configuration server that does the processing for the target virtual machine during replication.
    Configuration Server VMware Select the configuration server that manages replication for the target virtual machine.
    Run As Account VMware Select the account that target virtual machine uses.
    Replication Policy VMware and Hyper-V Select the replication policy that you want to use for the VMware or Hyper-V virtual machine.
    Storage Account VMware and Hyper-V Select the storage account that the target machine will use.
    There are two types of storage accounts, Standard and Premium.
    Log Storage Account VMware and Hyper-V Select the log storage account that the target machine will use.
    If you select a Premium storage account, you must select a Standard log storage account.
    This option is grayed out if you select a Standard storage account. The Standard storage account is used as the log storage account.
    Virtual Network VMware and Hyper-V Select the virtual network that the target machine belongs to.
    Resource Group VMware and Hyper-V Select the resource group that the target machine belongs to.
For more information about advanced properties to enable replication for a virtual machine, go to the Azure portal.
  1. Click OK.
The replication parameters or settings that you selected are sent to Azure and if the parameters are set correctly, a message is displayed. Replication status for the virtual machine refreshes every 10 minutes. To view more details, select a virtual machine and click Virtual Machine Detailsor view the status of the replication operation in theProtection Statuscolumn. After the replication is complete, theProtection StatusdisplaysProtected.
If an incorrect parameter is set, a pop-up message is displayed. You can click Enable Replication and select the parameters again.
If the replication task fails, Backup Exec displays replication errors for the specific virtual machine. To view the errors, click View Error Details. Alternatively, select the virtual machine, click Virtual Machine Details, which takes you to the Azure portal to view the replication errors.
