Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, Fig. 1 is a kind of virtual machine restoration methods schematic diagram provided in an embodiment of the present invention；
In a specific embodiment, a kind of virtual machine restoration methods are provided, comprising:
Step S1: it obtains the virtual machine that user sends and restores instruction.
The virtual machine that user's transmission can be obtained restores instruction, and virtual machine, which restores instruction, can restore instruction for current virtual machine
The multiple disks for restoring instruction or single disk recovery instruction of virtual machine and virtual machine with new virtual machine restore instruction, in user
When sending virtual machine recovery instruction, the maximum quantity for controlling the virtual machine of recovery is no more than system and threshold value is arranged.Intermediate medium magnetic
The amount of capacity of disk is determined based on snapshot or bitmap snapshot data.
Step S2: restore to instruct according to the virtual machine and establish virtual machine in the creation data storage equipment that user selects
Intermediate medium disk；
Equipment is stored according to the creation data of the target of user's selection, establishes intermediate medium disk, and control virtual machine and open
It moves on intermediate medium disk, is sent to backup data store and merge Backup Data request.
Step S3: the virtual machine is started based on the intermediate medium disk, and will be more in backup data store equipment
A backup snapshots file merges, and obtains the backup for restoring virtual machine and merges file；
It receives after merging Backup Data request, merges multiple backup snapshots files to migration and prepare catalogue, after the completion of merging
Management plane migrating channels are established, and replicates the backup file after merging and stores equipment specified path to creation data.
Step S4: backup merging file is copied in the creation data storage equipment, and will be standby after duplication
Part merges file and merges with the intermediate medium disk.
After copy backup merges file to creation data storage equipment specified path, virtual machine IO is hung, Zhi Houfa
Redirection intermediate medium disk read-write source file movement is played, intermediate medium read-write source file modification, successfully modified rear modification are executed
Virtual machine IO is solved first after success and is hung, then by intermediate medium disk with merge after backup file mergences, recovery process is complete
At.Merging for the first time is all backup snapshots files incorporated in backup storage, does not include intermediate medium disk, entire extensive
During multiple, virtual machine is operating status, and the data that virtual machine generates in this process are recorded in intermediate medium disk, because
This, so after completing backup and merging file migration, in order to reach the effect that virtual machine only operates on one piece of new disk
Fruit needs temporarily to be created that the intermediate medium disk come is deleted, i.e., namely merges intermediate medium disk and its data
Enter to migrate to the backup of creation data storage equipment and merge in file.
The present invention establishes intermediate medium disk by storing in equipment in creation data, can run virtual machine in this magnetic
On disk, intermediate medium disk is simultaneously not take up the host resource for being provided with virtual machine, and after starting virtual machine, Backup Data is deposited
Multiple backup snapshots file mergencess in equipment are stored up, backup is obtained and merges file, backup merging file are copied to described
Creation data stores in equipment, and the backup after duplication is merged file and merges completion virtual machine with the intermediate medium disk
Restore, realize reading data due to establishing to be flexible coupling between intermediate medium disk and backup merging file, and creates intermediate medium
Disk only needs 1-2 seconds time, can start virtual machine after creating successfully, and this improves virtual machine resume speeds, drops significantly
Low recovery virtual machine duration.
Based on above-mentioned any technical solution, the backup by after duplication merges file and merges with the intermediate medium disk
Before, further includes:
The read-write for executing the intermediate medium disk redirects so that backup after the duplication merge file and it is described in
Between media disks be associated with.
Wherein, the detailed process for executing the read-write redirection of intermediate medium disk is, by intermediate medium disk
BackingFile is directed toward a new file, and the backup after modifying the duplication merges father's snapshot document that file relies on originally,
Modification his father's snapshot document is intermediate medium disk, so that the backup after the duplication merges file and the intermediate medium disk
Association.
