Recovering Hyper-V Data

更新日期: 2010年4月

適用於: System Center Data Protection Manager 2010

DPM supports the following recovery scenarios:

 

Scenario Description

Recovering a virtual machine to an alternate location

The original VHD is deleted. DPM will recover the VHD and other configuration files on the original location by using the Hyper-V VSS writer. At the end of the recovery process, virtual machines will still be highly available.

Warning警告
The resource group must be present for recovery to happen. If the resource group is not available, recover to an alternate location and then make the virtual machine highly available.

Recovering a virtual machine to an alternate location

DPM supports alternate location recovery (ALR), which provides a seamless recovery of a protected Hyper-V virtual machine to a different Hyper-V host, independent of processor architecture. Hyper-V virtual machines that are recovered to a cluster node will not be highly available. For more information about how to make a virtual machine highly available, see To make a virtual machine highly available (http://go.microsoft.com/fwlink/?LinkID=160484).

Item-level recovery (ILR) of Hyper-V virtual machines

DPM supports item-level recovery (ILR), which allows you to do granular recovery of files, folders, volumes, and virtual hard disks (VHDs) from a host-level backup of Hyper-V virtual machines to a network share or a volume on a DPM protected server.

Tip秘訣
The DPM protection agent does not have to be installed inside the guest to perform item-level recovery.
