Microsoft azure site recovery step by step Service (DRaaS) service that lets you protect your on-premise datacenter workloads and VMs by replicating them to another location. During an outage, you can fail over to the protected machine to continue operations and recover data. The solution supports a wide range of on-premises workloads, including VMware and Hyper-V virtual machines that are managed by System Center VMM, as well as physical servers.
To use ASR, you create a Recovery Services vault, which contains all of your replication settings and manages the replication process. You also create the network and storage accounts that will be used to host the replicated VMs in the event of a disaster. You can choose to replicate your entire on-premises environment, or you can replicate specific machines and applications to the recovery location.
You can also select a recovery point that you want to restore data from, and you can configure the frequency of replication and the retention of replication data. If you’re not sure how frequently to replicate, you can use the ASR Deployment Planner to help you determine the replication frequency and settings for your DR environment.
Once your site is ready to handle a disaster, you can test out your DR plan by conducting a planned or unplanned failover. This means that you will move your on-premises VMs to the recovery location or another server, and then monitor their status in the event of a failure. If everything is working as expected, you can initiate a failback to the on-premises VMs by creating a failback policy and using a process server and master target server.
The process server and master target server are important for managing the VMs that you’ve replicated to the disaster recovery location. When you fail over a VM, it’s important to have the correct processes running on it to ensure that your application continues to function properly. If you have the process servers and master target servers configured correctly, you can perform a planned or unplanned failover with minimal impact to your production workloads.
The cost of an ASR site is much less than a traditional DR site. You only pay for the protection and the storage where the data is stored, which makes ASR a very affordable solution for most businesses. You can also use the ASR service to migrate on-premises servers to Azure if you’re replacing hardware or moving workloads between locations. However, if you’re moving to the cloud for other reasons, you should consider using Azure Migrate instead.
