Azure Site Recovery allows users to replicate on-premises virtual machines and physical servers to the cloud (Azure) or a secondary datacenter to contribute to business continuity and disaster recovery strategies. It can be deployed through either the classic Azure portal or the new Azure portal, and supports replication of VMware VMs, Hyper-V VMs, and physical servers managed by System Center Virtual Machine Manager (VMM) to Azure. The process involves setting up Azure infrastructure like storage and networks, installing agents on-premises, configuring replication settings, and testing failovers to ensure successful disaster recovery capabilities.

2. Azure Site Recovery contributes to your business continuity and disaster recovery (BCDR )strategy by orchestrating replication
of on-premises virtual machines and physical servers. You replicate servers and VMs from your primary on-premises
datacenter to the cloud (Azure), or to a secondary datacenter.
 Site Recovery can be deployed in both the classic portal and the Azure portal.
 Azure classic portal, you can support Site Recovery with the classic services management model.
 Azure portal, you can support the classic model, or Resource Manager deployments.

3.  Azure subscription Creation.
 Azure VPN Onprem to Azure.
 Azure storage account in vault region
 Create a Recovery Services vault.
 Failover form Azure .
 Download the necessary files.
 Install and register the Recovery Services agent.
 Test the failover on Azure.

5. •VMM server: An on-premises VMM server with one or more clouds.
•Hyper-V host or cluster: Hyper-V host servers or clusters managed in VMM
clouds.
•Azure Site Recovery Provider and Recovery services agent: During
deployment, you install the Azure Site Recovery Provider on the VMM server,
and the Microsoft Azure Recovery Services agent on Hyper-V host servers.
The Provider on the VMM server communicates with Site Recovery over
HTTPS 443 to replicate orchestration. The agent on the Hyper-V host server
replicates data to Azure storage over HTTPS 443 by default.
•Azure: You need an Azure subscription, an Azure storage account to store
replicated data, and an Azure virtual network so that Azure VMs are
connected to a network after failover.
