Microsoft azure site recovery is a disaster recovery solution that helps businesses protect their critical Hyper-V, VMware, and physical workloads and replicate them offsite. It provides a cost-effective way to meet business continuity requirements and minimize data loss in the event of a disaster.
This software lets you set up replication to an on-premises site, or to a public cloud. This is useful for companies that use a hybrid IT strategy and want to keep all their data in one place. It also eliminates the need for a secondary datacenter, which can have high initial and operational costs. In addition, it can help reduce the amount of time needed to recover from a disaster by automatically bringing your active sites back online.
With a simple configuration, you can replicate on-premises virtual machines and physical servers to Azure. Changes are replicated in real time and stored in a storage account. Then, if you experience a disaster, you can restore the VM from the Azure storage account. This service is very affordable because you only pay for the storage used. You can also use this service to transfer your VMs between two different locations.
The microsoft azure site recovery service is available through an extensive partner network, including Dell and Lenovo, which extends the availability of the software to businesses with more diverse IT infrastructures. It also supports a wide range of workloads and is compatible with multiple hardware platforms. In addition, the software offers robust support through online assistance and phone support. Its scalability and reliability make it an excellent choice for businesses with complex IT environments.
Before you begin a test failover, verify that your target region is ready for your replication traffic by ensuring that the subscription has enough resources to support the target size and that the target region has an Azure virtual network that matches the source one. You must also configure Network Security Group (NSG) rules to enable outbound replication. Specify the azure site recovery traffic in a NIC with a unique name and use service tags to minimize the complexity of the rules.
When you replicate a VM with ASR, it creates a virtual disk in the destination Azure Storage account. The disk contains the VM snapshot and other information, such as configuration settings, application settings, and logs. You can then mount the disk as a VM in the Azure site. The VM can run on the same server as the source or on a different one.
If you’re using a traditional recovery site, you must have a separate hot, warm, or cold site to maintain a second copy of the data and servers that you need in the event of a disaster. ASR eliminates this need by continuously replicating a copy of the on-premises data to a location in the Azure cloud. It’s an easy-to-use and cost-effective solution that lets you protect your critical VMs and 3rd party cloud services like AWS. You only pay for the storage and computing consumed, which is a more economical solution than maintaining a backup site with its associated initial and operational costs.
