Item-Level Recovery for Hyper-V
適用於: System Center Data Protection Manager 2010
System Center Data Protection Manager (DPM) provides both host-based and guest-based protection for 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.
You must have the Hyper-V role enabled on the DPM server to perform item-level recoveries. During item-level recovery, DPM has to mount the VHDs of the protected virtual machines.
重要
Item-level recovery does not support recovery of an item to its original location.
You cannot do an item-level recovery from within a virtual machine.The following table lists supported and unsupported scenarios when recovering files, folders, volumes, and VHDs using ILR in a Hyper-V virtual machine.
Scenario | Volumes or files/folders recovery | Virtual Hard Disk (VHD) recovery |
---|---|---|
From a virtual machine that has snapshots |
Yes (Only to Windows Server 2008 R2) |
Yes |
From a secondary DPM server |
Yes |
Yes |
From tape backups |
No |
Yes |
From NTFS volumes only |
Yes |
Not applicable |
From non-NTFS volumes |
No |
Entire VHD only |
From a VHD that is partitioned using dynamic disk partitioning |
No |
Entire VHD only |
重要
Mount points cannot be traversed or browsed when exploring a VHD for item-level recovery.
