What’s in DPM 2010 for Hyper-V R2

New features in DPM 2010, specific to virtualization, include:

• Support for Live Migration scenarios using cluster-shared volumes (CSV).

• Restore VMs to alternate Hyper-V hosts.

• Individual file-item restore from host-based backups, so you can protect the entire virtual machine from the host (no guest agent required), but selectively restore individual files from inside the VHDs.

• How DPM protects Virtual Machines

  DPM protects virtual machines based on the how the Hyper-V VSS* writer reports the capabilities of the VM:

  If the VM is VSS capable, meaning that the guest is running Windows Server 2003 or better, as well as VSS-capable applications like SQL Server – then the VM can typically be backed up while the VM is online (without interruption).

  · If the VM or one of its internal workloads is not VSS capable, then the VM will be momentarily hibernated so that it can be backed up and then resumed.

  In either case, DPM utilizes the Hyper-V VSS writer to synchronize block-level differences within the VHDs using a process called an “Express Full”, which identifies which blocks have changed in the entire VHD and then sends just the updated blocks or fragments. This provides a complete and consistent image of the virtual hard disk files on the DPM server or appliance. DPM maintains up to 512 shadow copies of the full VHD set by storing only the block-level differences between any two images.
