Why does ASR exist?
- Azure Site Recovery (ASR) is Microsoft’s Disaster Recovery as a Solution (DRAAS) built specifically for Azure workloads. ASR enables companies to recover from catastrophes quickly with minimal downtime. ASR can also be used as a tool to migrate existing workloads into Microsoft Azure, either from an on-premise environment or migrate workloads between regions and resource groups.
Who is ASR designed for?
- Companies that need to meet specific requirements or regulations for their industry such as ISO 27001.
- Companies who are sensitive to downtime or want to limit impact from region specific Azure outages.
- Companies who wish to migrate current workloads into Azure from an on-premise environment, between regions, or between resource groups.
- Anyone seeking a complete business continuity and disaster recovery (BCDR) strategy for their business.
When can ASR be used?
- Replication of Azure VMs from one Azure region to another
- Replication of on-premise VMWare VMs, Hyper-V VMs, physical Windows and Linux servers, and Azure Stack VMs to Azure
- Replication of on-premises VMWare VMs, Hyper-V VMs managed by System Center VMM, and physical servers to a secondary site.
- Replication of specific workloads running on a machine that’s supported for replication.
What are some of the key features of ASR?
- A simple BCDR solution – ASR is built into azure and can be managed entirely from within a single location.
- Data Resilience - Data is replicated inside of Azure storage with all the resilience and security provided by Azure.
- RTO and RPO Targets – Manage and meet organizational RTO/RPO targets with continuous replication at intervals as low as 30 seconds for Hyper-V servers.
- Easy and Flexible Failover– Test failover and disaster recovery scenarios without disrupting replication. Failovers can also be planned for expected outages with zero-data loss. Unplanned failovers can happen with minimal data loss and fail back to your primary site can be done easily when it’s available again.
How do I setup a basic ASR replication?
-
Log in to your Azure tenant
- Login to the Azure portal at https://portal.azure.com
-
Enable replication for an Azure VM
- In the Azure portal, click Virtual machines, and select the VM you want to replicate.
- In Operations, click Disaster recovery.
- In Configure disaster recovery > Target region select the target region to which you'll replicate.
- For this QuickStart, accept the other default settings.
- Click Enable replication. This starts a job to enable replication for the VM.
-
Verify your settings
- After the replication job has finished, you can check the replication status, modify replication settings, and test the deployment.
- In the VM menu, click Disaster recovery.
- You can verify replication health, the recovery points that have been created, and source, target regions on the map.
-
Clean up resources/stop replication
- The VM in the primary region stops replicating when you disable replication for it:
- The source replication settings are cleaned up automatically. The Site Recovery extension installed on the VM as part of the replication isn't removed and must be removed manually.
- Site Recovery billing for the VM stops.
- Stop replication as follows
- Select the VM.
- In Disaster recovery, click Disable Replication.
- The VM in the primary region stops replicating when you disable replication for it:
- After the replication job has finished, you can check the replication status, modify replication settings, and test the deployment.
