I already wrote about the product formerly known as DPM V3.
Here are some of the features I’m most excited about, regarding Hyper-V:
Protection of Live Migration-enabled servers running on CSV in Hyper-V R2
-Flexibility to protect virtual machines from Windows guests or from the hypervisor host
-Host-based backups will now enable single-item restores from within the VHD
-Ability to restore virtual machines to an alternative host
