Azure Site Recovery is a cloud-based disaster recovery solution that can help organizations manage their IT environments. It can be used to replicate on-premises virtual machines or physical servers to the Azure cloud and provide failover capability in case of a disaster. Additionally, it can also be used to test replication and failover processes without affecting the production environment.
This solution can be used to support multiple workloads, including virtual machines, physical servers, and Linux workloads. It can be used to implement a disaster recovery strategy that includes continuous replication and failover to the cloud, as well as an automatic backup of on-premises machines to the cloud and a restore mechanism. It can be used to help meet recovery time objectives (RTOs) and reduce business disruption, resulting in cost savings.
Using azure site recovery, customers can use continuous replication to ensure that changes to critical virtual machines or data are replicated in near real-time to the Azure cloud. This can be especially important for businesses that have strict RPO requirements. The service can also be used for scheduled replication, which allows businesses to choose a specific replication schedule that suits their needs.
In addition to enabling replication and failover, azure site recovery can be used to back up on-premises servers to the cloud and enable a restore process that can be initiated in the event of a disaster. It can also be used to test replication and failover capabilities by performing a DR drill, or by executing a failover scenario in a lab.
Azure site recovery provides a best-in-class RTO, which means that it can keep your general operations up and running within a few minutes after a disaster occurs. It can even reduce the time required to recover complex applications that run across a number of VMs.
It is easy to deploy and maintain a azure site recovery solution, as it doesn’t require any hardware on-premises or extensive management overhead. It is also easy to scale up and down, as the service can be expanded easily when additional VMs are needed or removed when they are no longer needed.
Once the azure site recovery solution is in place, it can be managed through the Azure portal. Organizations can configure policies based on a scope that is specified at the subscription level or resource group level. This allows them to enable Site Recovery for all new virtual machines added to the specified resources or groups. In the portal, a vault can be created to store replica images of all Site Recovery-protected machines. In order to perform a disaster recovery drill or test failover, the vault can be connected to the recovery services vault that contains the replicated virtual machines. In order to create a vault, an account must have the virtual machine contributor or site recovery contributor built-in role. It must also be part of a recovery services vault resource group.
