Disaster recovery is a set of policies that helps in the recovery or continuation of any system following a disaster. A disaster can be human-made or natural. It can be a cyberattack, equipment failure, power outages, and flooding.
So, to keep your business moving, the disaster recovery process is very much needed. It involves planning, testing, and restoring operations. It also comes with budget-friendly routes for a smaller organization.
Disaster Recovery for Azure IaaS VMs
Microsoft Azure is a cloud computing service. It helps in building, testing, deploying and managing services through Microsoft data centers. It also supports many different programming languages and frameworks.
If the region where your primary VM is deployed, face any kind of disaster, you may lose all your data. But azure can recover them. If you have created a virtual machine in the Microsoft Azure and want to protect it from a region outage, you can use Azure site recovery in this case.
It replicates the virtual machine to another Azure region. Moreover, Azure site recovery can also fail virtual machines to other regions if needed.
How to Set Up Disaster Recovery for Azure IaaS VMs
Setting up ASR for your virtual machine is quite easy. However, before that, you need to go through your planning and designing for the environment. Read the following prerequisites.
- Support matrix for Azure VM disaster recovery between Azure regions
- Azure to Azure disaster recovery architecture
Step 1: Log in to your Azura portal. On the menu, select virtual machine. Now select the virtual machine you want to replicate.
Step 2: In operation, select disaster recovery. Next, in the configure disaster recovery, go to the target region where you will replicate the VM.
Step 3: Now, you need to go through some advanced settings and select Review + Start Replication. Now, enable replication for the VM.
Step 4: Once the replication is done, you can see the replication status. For this, go to the menu, select virtual machine you want to verify. Next, under operation, select disaster recovery.
Failover Azura Virtual machine to other Azura region
Now you can either do production failover of your virtual machine or you can shutdown source machine and replicate the latest changes. This later one is possible is the source VM is still running. For more information visit Microsoft official document.
You can even failover multiple VMs using Recovery Plans. Hope you have liked the article and found it useful.
