Answer
B. Azure Site Recovery
Explanation
Azure Site Recovery enables businesses to replicate their on-premises virtual machines and applications to Azure, ensuring disaster recovery and business continuity in the event of a failure.
Azure Site Recovery (ASR) is designed to help organizations ensure business continuity by replicating on-premises virtual machines (VMs), physical servers, and applications to Azure. In the event of a disaster or outage at the primary site, ASR enables rapid failover to Azure, allowing users to continue accessing critical workloads with minimal downtime.
- Replication Process: ASR continuously replicates data from the source environment (on-premises or another Azure region) to Azure Storage. This includes initial full replication and ongoing synchronization of changes, ensuring up-to-date recovery points.
- Failover and Failback: During a disaster, you can initiate a failover to Azure, where Azure VMs are created from the replicated data. Once the primary site is restored, ASR supports failback, replicating changes back to the original environment.
- Testing and Monitoring: ASR allows for non-disruptive disaster recovery drills, enabling organizations to test their recovery plans without impacting production workloads. Real-time monitoring and status updates are available through the Azure portal.
- Centralized Management: All replication, failover, and failback operations are managed from a single Recovery Services vault in the Azure portal, simplifying disaster recovery planning and execution.
- Supported Scenarios: ASR supports replication for VMware and Hyper-V VMs, physical servers (Windows and Linux), and Azure VMs across regions, making it a versatile solution for hybrid environments.
Azure Site Recovery enables businesses to replicate their on-premises virtual machines and applications to Azure, providing comprehensive disaster recovery and business continuity by orchestrating failover, failback, and ongoing replication from a centralized management console.
