The technology of interface realizes, and can only realize this demand by two virtual platforms, will return to another void by virtual machine
On planization platform.This hardware that can be greatly improved user and time cost, most client represents and cannot accept, and proposes
Wish to back up manufacturer provide a kind of independent of former virtual machine and the scheme of recovering virtual machine by the way of newly-built virtual machine.
On the other hand, directly invoke the virtual machine that VSS interface recovers to integrate backup snapshots and retain user's snapshot.
Owing to Hyper-v virtual machine and virtual machine snapshot are respectively provided with global uniqueness, when third party backs up manufacturer rashly same virtual
Change platform and recover the newly-built virtual machine independent of former virtual machine by some mode, can thoroughly upset the structure of virtual machine, lead
Causing such as virtual machine backup snapshots to integrate, lose, former virtual machine and newly-built virtual machine use user's snapshot etc. to estimate
Gross error, not only resulting in new virtual machine can not recover, and also can make former virtual machine crashes, brings to user and cannot assess

Character string, it have recorded the GUID of backup virtual machine and all of fileinfo, such as: the backup listed files of virtual machine,
Preserve when the file organization relation of virtual machine, backup: profile information, snapshot document title, the content of snapshot document, magnetic
Dish file data etc..Described method specifically includes that
Step S101, newly-built GUID: the VSS module information preserved when reading backup, records former virtual machine GUID, and at random
Generate a new GUID.Resolve and record the file organization relation of record in VSS backup module information, i.e. virtual machine file is true
Real name claims and the one-to-one relationship of its another name in VSS assembly, therefrom filters out all of backup snapshots file, and generates
The new GUID of equivalent amount；Resolve and record all listed files backed up in VSS backup module information, therefrom filter out
All of user's snapshot document, and generate the new GUID of equivalent amount.
Step S102, replacement GUID: all above GUID recorded in traversal lookup VSS backup module information, and respectively
