Hyper-V Recovery Manager uses the capabilities provided by Windows Server's Hyper-V Replica feature to backup VMs from a primary data center to a secondary data center. In the event of an outage at the primary data center, Hyper-V Recovery Manager automates the failover process to bring workloads back up at the secondary site with minimal downtime. Hyper-V Recovery Manager can also be used to test the recovery process.
Windows Azure customers can access Hyper-V Recovery Manager through the Windows Azure customer portal. Unlike Windows Azure Backup, Windows Azure Hyper-V Recovery Manager does not send backups to a public cloud. Instead, the public-cloud based service automates the backup and recovery of VMs located in on-premises private clouds, moving VMs from one private cloud to another. The service is only available on Virtual Machine Manager servers in System Center 2012 SP1 and System Center 2012 R2.
Hyper-V Replica is an included feature in the latest version of Hyper-V, but the Windows Azure Hyper-V Recovery Manager is a subscription-based service, currently priced at $16 per month for every protected VM. Microsoft released Windows Azure Hyper-V Recovery Manager in January, 2014.
