Before we dive into planning and implementing a disaster recovery plan for Azure Virtual Desktop, it’s important to first understand the necessity of such a plan. Disaster recovery is a crucial part of any organizational operation as it helps to maintain continuity of service. For Azure Virtual Desktop (formerly known as Windows Virtual Desktop), having a robust disaster recovery plan is key to ensuring that your virtual desktop infrastructure (VDI) stays operational, even in the face of serious incidents. AZ-140, Configuring and Operating Microsoft Azure Virtual Desktop, emphasizes on this critical aspect of operation management.
2. Principles of Disaster Recovery Plan
A disaster recovery plan revolves around three main principles:
- RTO (Recovery Time Object): This is the maximum acceptable length of time that can elapse before the lack of a service significantly impacts an organization.
- RPO (Recovery Point Object): This is the maximum targeted period in which data (transactions) might be lost from an IT service due to a major incident.
- ERT (Estimated Recovery Time): The predicted time to recover services after an outage.
3. Phases in Implementing a Disaster Recovery Plan
Here’s a high-level view of the key phases in implementing a disaster recovery plan for Azure Virtual Desktop:
- Planning: Developing the disaster recovery strategy, setting RTO and RPO, and identifying critical workloads.
- Implementing: Setting up recovery services and implementing the prepared strategies.
- Testing: Regularly conducting disaster recovery drills to ensure the preparedness of the plan.
4. Planning and Implementing a Disaster Recovery Plan for Azure Virtual Desktop
To plan and implement a disaster recovery solution in an Azure Virtual Desktop infrastructure, you can take advantage of Azure Site Recovery that orchestrates and manages disaster recovery for Azure VMs.
Here are the steps to follow:
- Deploy the Azure Virtual Desktop infrastructure in more than one Azure region.
- Set up Azure Site Recovery between your primary and secondary Azure regions. During the setup, you can specify the settings, such as the replication frequency (RPO goal) and the retention of recovery points.
Example: Implementing Azure Site Recovery
Connect to the Azure portal, then search for ‘Site Recovery.’
# Following is an example of setting up Site Recovery
New-AzRecoveryServicesVault -ResourceGroupName “contosoResourceGroup” -Name “contosoVault” -Location “West US”
Periodically trigger disaster recovery drills to ensure the readiness of your plan.
5. Testing the Disaster Recovery Plan
Once the disaster recovery plan is implemented, it requires regular testing to ensure its effectiveness. You can simulate a disaster recovery drill using Azure Site Recovery. During the test, you can review the connectivity and performance of the virtual desktops in the secondary region.
6. Conclusion
In the AZ-140 Configuring and Operating Microsoft Azure Virtual Desktop exam, understanding how to plan and implement a disaster recovery plan is vital. Leveraging Azure Site Recovery as a part of the Azure disaster recovery strategy can ensure that your services remain resilient, maintaining productivity even during service interruptions or outages.

Interview Questions
What is Azure Virtual Desktop?
Azure Virtual Desktop is a modern cloud-based desktop and app virtualization service that empowers remote work by allowing safe and secure access to your desktops and apps anywhere.
Why is a disaster recovery plan essential for Azure Virtual Desktop?
A disaster recovery plan is critical to ensure business continuity in case of service disruption or catastrophic event. It helps to restore operations quickly and avoid data loss or prevent long service downtime.
How does Azure Site Recovery contribute to a disaster recovery plan for Azure Virtual Desktop?
Azure Site Recovery is a Microsoft service used for disaster recovery. It replicates workloads running on physical and virtual machines from a primary location to a secondary location and helps in failing over during outages, and fail back when the primary location is up again.
What is Azure Backup’s role in a disaster recovery plan for Azure Virtual Desktop?
Azure Backup provides independent and isolated backups to guard against unintentional destruction of the data on your VMs. It provides scalable, secure, and cost-effective solutions to back up your data and recover it from Azure.
How can you safeguard Azure Virtual Desktop data?
You can protect Azure Virtual Desktop data by ensuring regular backups and snapshots and using Azure Site Recovery service for disaster recovery. Also, define clear and structured recovery processes and make sure access control policies are in place.
What are the critical components to consider when implementing a disaster recovery plan for Azure Virtual Desktop?
The key components include: Availability Set and Availability Zones to ensure VM availability, Azure Site Recovery for recovery at the time of disaster, Azure Backup for data protection, and Azure Traffic Manager for network level resilience.
How does Azure Traffic Manager contribute to a disaster recovery plan?
Azure Traffic Manager improves the availability of critical applications by routing traffic to the best-performing hosting location. In case of a disaster, it contributes to the continuity of operations by redirecting the traffic to a secondary site.
What is the purpose of an availability set within Azure Virtual Desktop disaster recovery planning?
An Availability Set is a logical grouping of VMs within a data center that allows Azure to understand how your application is built to provide for redundancy and availability. It ensures that during either a planned or unplanned maintenance event, at least one virtual machine is available and meets the 99.95% Azure SLA.
How does Geo-Replication in Azure SQL Database support disaster recovery?
Azure SQL Database’s Geo-Replication feature allows for the creation of readable secondary databases in different geographical regions. In case of a regional failure, there is an automatic failover to the geo-replicated backup, ensuring business continuity.
What should be the primary aim of disaster recovery planning?
The primary aim of disaster recovery planning is to minimize downtime and data loss.
What is the relevance of Recovery Time Objective (RTO) and Recovery Point Objective (RPO) in disaster recovery planning?
RTO is the targeted duration of time within which a business process must be restored after a disaster in order to avoid unacceptable consequences. RPO is the maximum acceptable amount of data loss measured in time. Both these objectives must be well defined in a disaster recovery planning.
In Azure Virtual Desktop, how is data replication achieved?
Data replication is achieved using Azure Site Recovery, which ensures the replication of workloads running on virtual machines in real-time from a primary to a secondary location.
What strategies can enhance the effectiveness of a disaster recovery plan in Azure Virtual Desktop?
