The Advanced Copy function of the ETERNUS Disk storage system can link with VSS and the Hyper-V VSS writer to implement restoration of backed up Hyper-V Guest OSes.
Figure 9.2 Restoration processing image
If the Guest OS to be restored is currently operating, it will be stopped and deleted.
When restoration is completed, the Guest OS will be re-registered.
If the online backup data are stored on tape, restore the files directly from the tape to the transaction volume.
Note
The Guest OS cannot be restored to a location (file path) that is different from the original backup location.
Restoration is possible only to the originally backed up location.
