Azure Site Recovery helps you to protect important applications by coordinating the replication and recovery of physical or virtual machines. You can replicate to your own datacenter, to a hosting service provider, or even to Azure to avoid the expense and complexity of building and managing your own secondary location.
Simple, Automated Protection
Your environment can be protected by automating the replication of the virtual machines based on policies that you set and control. Site Recovery coordinates and manages the ongoing replication of data by integrating with existing technologies such as Hyper-V Replica, System Center, and SQL Server AlwaysOn.
Site Recovery also integrates with SAN replication options from storage vendors such as NetApp, HP, and EMC to help further simplify and improve your disaster recovery protection. This capability is currently in preview.
Replication and recovery to Azure
You can further simplify your disaster recovery protection by replicating to Azure and still benefit from the simplicity, automation, customizable recovery plans, health monitoring, and orchestrated recovery the service provides. One of the primary roadblocks to comprehensive protection of applications is the expense of establishing and maintaining a secondary site for disaster recovery. Now Azure can be your disaster recovery site.
Continuous Health Monitoring
Site Recovery monitors the state of your protected instances continuously and remotely from Azure. When replicating between two sites you control, your virtual machines’ data and replication remains on your networks. All communication with Azure is encrypted. When replicating to Azure as the secondary site, your data is encrypted and you can also select encryption for data at-rest.
The service helps automate the orderly recovery of services in the event of a site outage at the primary datacenter. Virtual machines can be brought up in an orchestrated fashion to help restore service quickly, even for complex multi-tier workloads. Recovery plans are simple to create through the Azure management portal, where they are stored. The plans can be as simple or as advanced as your business requirements demand, including the execution of custom Windows PowerShell scripts and pauses for manual interventions. Networks can also be customized by mapping virtual networks between the primary and recovery sites. These plans can be tested whenever you like without disrupting the services at your primary location.
