Wherein, virtual machine be by software simulate one have the function of complete hardware system, operate in one completely every
From the complete computers in environment, a variety of mirror-image formats are can be used in the local disk in virtual machine, for example, raw is (without adding
Work), qcow2, VMDK (the virtual disk format of VMWare Virtual Machine Disk Format, virtual machine VMware)
Deng being described in detail by taking the mirror-image format of qcow2 as an example in the embodiment of the present invention.
For qcow2 mirror-image format, the file of two qcow2 mirror-image formats is generally included in the local disk of virtual machine,
That is foundation image and increment mirror image, the data in foundation image are usually read-only status, and the data in increment mirror image are usually can

Data after data in foundation image are modified are stored in increment mirror image.
In an implementation, as shown in Fig. 2, virtual machine application can be equipped in terminal, for creating virtual machine.If
User needs to create virtual machine, then can click the creation virtual machine key in virtual machine application, and terminal generates creation and asks
It asks, multiple foundation images can be previously stored in terminal, when terminal receives request to create, virtual machine application can be passed through
Program prompt user selects foundation image of the foundation image as virtual machine from above-mentioned multiple foundation images, then, by
Step guidance user carries out subsequent operation, for example, the size of prompt user input or selection virtual machine local disk, prompt user's choosing
The position etc. for selecting virtual machine installation, to complete the creation process of virtual machine.After the completion of virtual machine creating, this earth magnetism of virtual machine
It include a foundation image and an increment mirror image (i.e. the first increment mirror image) in disk, user can install certain soft for virtual machine
Part, corresponding data can store in the first increment mirror image.In order to allow virtual machine in the event of a failure can fast quick-recovery, or
Person can quickly create the virtual machine of multiple same configurations, can back up to the first increment mirror image in virtual machine, specifically
Ground can be equipped with the backup application backed up to the increment mirror image in virtual machine in terminal, in order to reinforce user's
The backup functionality of backup application can be integrated into virtual machine application by usage experience, and the embodiment of the present invention is with void
It incorporates in quasi- machine application program and is described in detail for the backup functionality of backup application, for using back-up application journey
Similarly, details are not described herein, and concrete processing procedure can for the treatment process that increment mirror image in ordered pair virtual machine is backed up
With are as follows: it, can be with if user needs to back up the first increment mirror image in current virtual machine (i.e. target virtual machine)
Click backup key, terminal display information input frame, user can input Data Identification to be filtered in information input frame, such as to
Cross title or the number etc. of filter data, wherein Data Identification to be filtered corresponding data can be to be stored in target virtual machine
Log class data etc., after the completion of input, user can click determining key, at this point, the available user of terminal is in information input
The Data Identification to be filtered inputted in frame, generates the backup request of the first increment mirror image of corresponding target virtual machine, and terminal can be with
Receive the backup request.
Step 102, the second increment mirror image is created, the corresponding data of Data Identification to be filtered will be removed in the first increment mirror image
Outer other data copy in the second increment mirror image.
Wherein, the first increment mirror image and the corresponding foundation image of the second increment mirror image are identical.
In an implementation, when terminal receives backup request, the increasing of a blank can be created by virtual machine application
It measures mirror image (i.e. the second increment mirror image), the corresponding relationship of data and Data Identification can be previously stored in the first increment mirror image,
Then, terminal can search in the above-mentioned corresponding relationship of the first increment mirrored storage, and it is corresponding to obtain Data Identification to be filtered
Data, terminal can be marked obtained data, and unmarked data are copied in the second increment mirror image, this
When, other numbers in addition to the corresponding data of Data Identification to be filtered for being stored in the second increment mirror image in the first increment mirror image
According to.
Optionally, the processing mode of above-mentioned steps 102 can be varied, three kinds of optional processing modes presented below,
It can specifically include following three kinds of modes:
Mode one creates the second increment mirror image if target virtual machine is currently not based on the work of the first increment mirror image, will
First increment mirror image and the second increment mirror image carry out carry, will remove the corresponding number of Data Identification to be filtered in the first increment mirror image
It is copied in the second increment mirror image according to outer other data, cancels the carry to the second increment mirror image.
Wherein, carry, which refers to, is articulated to the increment mirror image in virtual machine in terminal in some already present catalogue, for example,
In the catalogue of hard disk in terminal.
In an implementation, when terminal receives backup request, whether terminal can detecte target virtual machine currently based on the
One increment mirror image work, if the terminal determine that target virtual machine is not presently within starting state or the current base of target virtual machine
In other increment mirror images work in addition to the first increment mirror image, then terminal can create the second increment by virtual machine application
Mirror image, wherein the second increment mirror image can be the increment mirror image of blank, since virtual machine application is usually not arranged certain
Data in a increment mirror image copy to the function of another increment mirror image, and therefore, in order to achieve the above object, terminal can incite somebody to action
First increment mirror image and the second increment mirror image carry, at this point, the icon of two hard disks will be increased in the catalogue of the hard disk in terminal,
In this way, terminal can be written and read the data in the first increment mirror image and the second increment mirror image, then, terminal can be incited somebody to action
Other data in addition to the corresponding data of Data Identification to be filtered in first increment mirror image copy in the second increment mirror image, multiple
After the completion of system, terminal can unload the second increment mirror image from the catalogue of above-mentioned hard disk, at this point, the second increasing in the catalogue of hard disk
The icon for measuring the corresponding hard disk of mirror image disappears.Terminal can also unload the first increment mirror image from the catalogue of above-mentioned hard disk, this
When, the icon of the corresponding hard disk of the first increment mirror image disappears in the catalogue of hard disk, in this way, can make target virtual machine is subsequent can
To be worked based on the first increment mirror image.
Mode two creates corresponding first increment mirror image if target virtual machine is currently based on the work of the first increment mirror image
Snapshot image, the data in the first increment mirror image are copied in snapshot image, and set third increment for snapshot image
Mirror image；The second increment mirror image is created, the first increment mirror image and the second increment mirror image are subjected to carry, it will be in the first increment mirror image
Other data in addition to the corresponding data of Data Identification to be filtered copy in the second increment mirror image, cancel to the second increment mirror image
Carry.
Wherein, the mirror image of snapshot image to be a kind of with some increment mirror image be basic mirror image, is stored in snapshot image pair
Data in the increment mirror image modify after data and user's write-in new data etc..
It in an implementation, if a terminal detects that target virtual machine is in working condition, and is based on the first increment mirror
As work, then terminal can create the snapshot image of the first increment mirror image by virtual machine application, at this point, target virtual machine
From becoming working based on snapshot image based on the work of the first increment mirror image, then, terminal can set increment for snapshot image
Mirror image, specifically, since target virtual machine is currently based on snapshot image work, target virtual machine can be to the first increment mirror
Data in picture and snapshot image are written and read, in this way, terminal can will be in the first increment mirror image by target virtual machine
Data copy in snapshot image, after the completion of duplication, snapshot image can be revised as third increment mirror image by terminal, and third increases
It is identical to measure mirror image foundation image corresponding with the first increment mirror image.
Terminal can create an increment mirror image (i.e. the second increment mirror image) by virtual machine application, wherein second
Increment mirror image can be the increment mirror image an of blank, and then, terminal can hang the first increment mirror image and the second increment mirror image
It is downloaded in terminal in the catalogue of hard disk, at this point, terminal can carry out the data in the first increment mirror image and the second increment mirror image
Read-write operation, in this way, terminal can be by other numbers in addition to the corresponding data of Data Identification to be filtered in the first increment mirror image
According to copying in the second increment mirror image, after the completion of duplication, terminal can unload the second increment mirror image from the catalogue of above-mentioned hard disk
It carries, terminal can also unload the first increment mirror image, and in order to save disk occupied space, user can be by the first increment mirror
As deleting.
Mode three creates corresponding first increment mirror image if target virtual machine is currently based on the work of the first increment mirror image
Snapshot image, the first increment mirror image is subjected to read-only carry, and the second increment mirror image is subjected to carry, by the first increment mirror image
In other data in addition to the corresponding data of Data Identification to be filtered copy in the second increment mirror image, cancel to the second increment
The carry of mirror image；Cancel snapshot image.
Wherein, it can be set in virtual machine application there are two types of carry mode, such as read-only carry and carry.Read-only carry
When can be to increment mirror image progress carry, terminal can only read the data in increment mirror image, but cannot modify in increment mirror image
Data or data are written into increment mirror image, the increment mirror image for carrying out read-only carry can be corresponding virtual machine and be used
Increment mirror image.When carry be can be to increment mirror image progress carry, terminal can be written and read the data in increment mirror image
Operation, the increment mirror image for carrying out carry is usually the increment mirror image for being not in use state.
In an implementation, if target virtual machine is currently based on the work of the first increment mirror image, terminal can create the first increasing
The snapshot image of mirror image is measured, at this point, target virtual machine is based on snapshot image work from becoming based on the work of the first increment mirror image, the
One increment mirror image is the foundation image of snapshot image, and data therein are used by target virtual machine, at this point, saving disk occupies sky
Between, the first increment mirror image can be carried out to read-only carry, meanwhile, carry can be carried out to the second increment mirror image, then, terminal can
Other data in addition to the corresponding data of Data Identification to be filtered in the first increment mirror image are copied to the second increment mirror image
In, after the completion of duplication, terminal can be unloaded the second increment mirror image, at this point, terminal can also by the first increment mirror image into
Row unloading, after completing the above process, terminal can cancel snapshot image by virtual machine application, and specifically, terminal can be with
Data in first increment mirror image are copied in snapshot image, and set third increment mirror image for snapshot image, at this point, mesh
Virtual machine is marked to work based on third increment mirror image.
Terminal can also be without the processing of the cancellation snapshot image in aforesaid way three, the then processing of above-mentioned steps 102
If mode can also include: that target virtual machine is currently based on the work of the first increment mirror image, corresponding first increment mirror image is created
Snapshot image, the first increment mirror image is subjected to read-only carry, and the second increment mirror image is subjected to carry, by the first increment mirror image
In other data in addition to the corresponding data of Data Identification to be filtered copy in the second increment mirror image, cancel to the second increment
The carry of mirror image.
The treatment process of above-mentioned steps 102 can also include other modes, for example, terminal can be created in addition to aforesaid way
The snapshot image for building corresponding first increment mirror image, the data in the first increment mirror image are copied in snapshot image, and by snapshot
Mirror settings be third increment mirror image, it is then possible to by the first increment mirror image carry out carry, delete the first increment mirror image in
The corresponding data of Data Identification are filtered, cancel the carry to the first increment mirror image, corresponding subsequent treatment process can be with are as follows: eventually
End can back up the data in the first increment mirror image, be the backup of the first increment mirror image by obtained backup data store
Data, due to the characteristic of qcow2 mirror-image format, although deleting certain data in above-mentioned processing method, the first increment mirror
The disk space that data as in occupy is there is no reducing, and for aforesaid way, terminal can also pass through virtual machine application
Capacity reducing is carried out to the disk space that the first increment mirror image occupies, to reach effect identical with above-mentioned three kinds of modes.
Step 103, the data in the second increment mirror image are backed up, is the first increment by obtained backup data store
The Backup Data of mirror image.
In an implementation, the data in the available second increment mirror image of terminal, and the data are backed up, it is backed up
Data, user can preset the storage address of a Backup Data, can be by the backup number after terminal obtains Backup Data
According to storage into the corresponding storage region of above-mentioned storage address.
It is alternatively possible to which backup server is arranged for backup procedure, backup server can carry out corresponding data standby
Part and storage, correspondingly, the treatment process of above-mentioned steps 103 may include the following contents: being carried to backup server transmission
The backup messages of the mark of data and the first increment mirror image in second increment mirror image, so that backup server is by the second increment mirror
Data as in are stored as the Backup Data of the first increment mirror image.
In an implementation, the mark (such as first of the data in the available second increment mirror image of terminal and the first increment mirror image
The title etc. of increment mirror image), backup messages are generated, backup server is sent to, it, can when backup server receives backup messages
To extract the mark and data of the first increment mirror image therein, the mark and the data can be corresponded to storage by backup server,
To store the Backup Data of the first increment mirror image in backup server.Backup server also available first increment mirror
As the mark of corresponding foundation image, it is then possible to by the number in the data and the second increment mirror image in corresponding foundation image
It is stored according to the Backup Data as target virtual machine.
