the top 8 improvements done to Hyper-V Replica in Windows Server 2012 R2. We will be diving deep into each of these features in the coming weeks through blog posts and TechNet articles.<\/p>\n

Seamless Upgrade<\/p>\n

You can upgrade from Windows Server 2012 to Windows Server 2012 R2 without having to re-IR your protected VMs. With new features such as cross-version live migration, it is easy to maintain your DR story across OS upgrades. You can also choose to upgrade your primary site and replica site at different times as Hyper-V Replica will replicate your virtual machines from a Windows Server 2012 environment to a Windows Server 2012 R2 environment.<\/p>\n

\"HYPER2\"<\/a><\/p>\n

30 second replication frequency<\/p>\n

Windows Server 2012 allowed customers to replicate their virtual machines at a preset 5minute replication frequency. Our aspirations to bring down this replication frequency was backed by customer\u2019s asks on providing the flexibility to set different replication frequencies to diffe\"HYPER1\"<\/a>rent virtual machines. With Windows Server 2012 R2, you can now asynchronously replicate your virtual machines at either 30second, 5mins or 15mins frequency.<\/p>\n

30sec<\/p>\n

Additional Recovery Points<\/p>\n

Customers can now have a longer retention with 24 recovery points. These 24 (up from 16 in Windows Server 2012) recovery points are spaced at an hour\u2019s interval.<\/p>\n

Linux guest OS support\"HYPER3\"<\/a><\/p>\n

Hyper-V Replica, since it\u2019s first release has been agnostic to the application and guest OS. However certain capabilities were unavailable on non-Windows guest OS in it\u2019s initial avatar. With Windows Server 2012 R2, we are tightly integrated with non-Windows OS to provide file-system consistent snapshots and inject IP addresses as part of the failover workflow.<\/p>\n

Extended Replication<\/p>\n

You can now \u2018extend\u2019 your replica copy to a third site using the \u2018Extended replication\u2019 feature. The functionality provides an added layer of protection to recover from your disaster. You can now have a replica copy within your site (eg: ClusterA->ClusterB in your primary datacenter) and extend the replication for the protected VMs from ClusterB->ClusterC (in your secondary data center).<\/p>\n

To recover from a disaster in ClusterA, you can now quickly failover to the VMs in ClusterB and continue to protect them to ClusterC. More on extended replication capabilities in the coming weeks.<\/p>\n

Performance Improvements<\/p>\n

Significant architectural investments were made to lower the IOPS and storage resources required on the Replica server. The most important of these was to move away from snapshot-based recovery points to \u201cundo logs\u201d based recovery points. These changes have a profound impact on the way the system scales up and consumes resources, and will be covered in greater detail in the coming weeks.<\/p>\n

Online Resize<\/p>\n

In Windows Server 2012 Hyper-V Replica was closely integrated with the various Hyper-V features such as VM migration, storage migration etc. Windows Server 2012 R2 allows you to resize a running VM and if your VM is protected \u2013 you can continue to replicate the virtual machine without having to re-IR the VM.<\/p>\n","protected":false},"excerpt":{"rendered":"
