Azure Site Recovery test step

Azure Site recovery test step starts and stops an ASR recovery plan in test failover mode. It is always added to the step list as a pair of test steps, one for starting the recovery plan and one for stopping it. Other steps between the start and stop steps can be used to test the virtual machines in the recovery plan.

Warning Virtual machines started by the recovery plan generate Wenenu usage charges. See our pricing page for the details. Virtual machines started for the same protected item multiple times in the same monthly billing period are counted only once.

When the start step is executed, the selected recovery plan is started in test failover mode with the given recovery point type using the selected virtual network as a target. Users can select subnets in the target virtual network to instruct Wenenu to start test agent virtual machines in the selected subnets. The started test agents can be used as an execution point for subsequent test steps.

The test agent virtual machines run Ubuntu 18.04-LTS and they are Standard_D2_v3 size with a single NIC and OS disk. They will be placed in the resource group of the recovery plan with the name of wenenu_<identifier>.

When the stop step is executed, Wenenu first deletes the test agent virtual machines in the previously selected subnets. Then it stops the test failover of the ASR recovery plan.

The step uses an Azure Service Principal service connector to communicate with the Azure ARM API. The service principal must have the appropriate Azure rights to start the recovery plan in test failover mode as well as to start and stop test agent VMs if necessary.

Note ASR test step is executed by special Wenenu agents, it is not required to specify a test agent for the place of execution. The credentials of the service connector do not leave our secure environment.
Important The ASR recovery plan in test failover and the optionally started virtual machines generate Azure charges. Wenenu implements a robust retry mechanism to ensure the cleanup of the Azure resources, but despite all of our efforts, errors, for example, network segregation or hardware failure can prevent the cleanup of resources. As a best practice, users should check whether the Azure resources are cleaned up if a stop step ends with failure.
