Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Refer to a kind of virtual machine restoration methods schematic diagram that Fig. 1, Fig. 1 provide for the embodiment of the present invention；
In a kind of detailed description of the invention, it is provided that a kind of virtual machine restoration methods, including:
Step S1: obtain the virtual machine recovery instruction that user sends.
Can obtain the virtual machine recovery instruction that user sends, it can be that current virtual machine recovers instruction that virtual machine recovers instruction
Recover instruction with new virtual machine, or single disk of virtual machine recovers to instruct the many disks with virtual machine and recovers instruction, user
When sending virtual machine recovery instruction, the maximum quantity of the virtual machine controlling recovery arranges threshold value less than system.Intermediate medium magnetic
The amount of capacity of dish determines based on snapshot or bitmap snapshot data.
Step S2: recover instruction according to described virtual machine and set up virtual machine in the creation data storage device that user selects
Intermediate medium disk；
The creation data storage device of target selected according to user, sets up intermediate medium disk, and controls virtual machine and open
Move on intermediate medium disk, send to backup data store and merge Backup Data request.
Step S3: start described virtual machine based on described intermediate medium disk, and by many in backup data store equipment
Individual backup snapshots file merges, and obtains the backup for recovering virtual machine and merges file；
After receiving merging Backup Data request, merge multiple backup snapshots file to migrating preparation catalogue, after having merged
Set up management plane migrating channels, and replicate the backup file after merging to creation data storage device specified path.
Step S4: by described backup merge file be copied in described creation data storage device, and will replicate after standby
Part merges file and merges with described intermediate medium disk.
Copy backup merges file to after creation data storage device specified path, by virtual machine IO suspension, sends out afterwards
Rise redirect intermediate medium disk read-write source file action, perform intermediate medium read-write source file amendment, successfully modified after amendment
After success first by virtual machine IO solve hang, then by intermediate medium disk with merge after backup Piece file mergence, recovery process is complete
Become.Merging for the first time is to incorporate all backup snapshots files in backup storage, does not comprise intermediate medium disk, whole extensive
During Fu, virtual machine is running status, the data that virtual machine produces in this process, records at intermediate medium disk, because of
This, so after completing backup and merging file migration, only operating in the effect on one piece of new disk to reach virtual machine
Really, need to delete the intermediate medium disk temporarily creating out, the most namely intermediate medium disk and its data are merged
The backup entering to migrate to creation data storage device merges in file.
The present invention is by setting up intermediate medium disk in creation data storage device, it is possible to virtual machine operates in this magnetic
On dish, intermediate medium disk is also not take up being provided with the host resource of virtual machine, after starting virtual machine, is deposited by Backup Data
Multiple backup snapshots Piece file mergences in storage equipment, obtain backup and merge file, described backup is merged file and is copied to described
In creation data storage device, and will replicate after backup merge file merged virtual machine with described intermediate medium disk
Recover, realize digital independent owing to intermediate medium disk and backup merge to set up to be flexible coupling between file, and create intermediate medium
Disk only needs 1-2 time second, can start virtual machine, this improves virtual machine resume speed, significantly drop after creating successfully
Low recovery virtual machine duration.
Based on above-mentioned any technical scheme, described will replicate after backup merge file and merge with described intermediate medium disk
Before, also include:
The read-write performing described intermediate medium disk redirects so that backup after described duplication merge file with described in
Between media disks association.
Wherein, the detailed process of the read-write redirection performing intermediate medium disk is, by intermediate medium disk
BackingFile points to a new file, revises the backup after described duplication and merges father's snapshot document that file relies on originally,
Amendment his father's snapshot document is intermediate medium disk so that the backup after described duplication merges file and described intermediate medium disk
Association.
Based on above-mentioned any technical scheme, in above-mentioned virtual machine restoration methods, described in obtain backup and merge after file,
Also include:
Set up management net tunnel, described backup is merged file by described management net tunnel thermophoresis to described production number
According in storage device.
Wherein, management net tunnel is set up, it is possible to effectively the migration thermophoresis of backup snapshots file chain set to data storage
In Bei, accelerate migration velocity.
As in figure 2 it is shown, a kind of virtual machine recovery device schematic diagram that Fig. 2 provides for the embodiment of the present invention.
