Embodiment two
Embodiments providing a kind of method of data backup, the method can be realized by terminal, and this terminal can be arbitrary terminal, such as desktop computer, notebook computer etc.
Below in conjunction with embodiment, the treatment scheme shown in Fig. 1 being described in detail, content can be as follows:
Step 101, receives the backup request of the first increment mirror image of corresponding target virtual machine, carries data to be filtered mark in backup request.
Wherein, virtual machine be one simulated by software there is complete hardware system function, complete computers in a completely isolated environment that operates in, this local disk in virtual machine can use multiple mirror-image format, such as, raw (without processing), qcow2, VMDK (VMWareVirtualMachineDiskFormat, the virtual disk form of virtual machine VMware) etc., the embodiment of the present invention is described in detail for the mirror-image format of qcow2.
For qcow2 mirror-image format, this local disk of virtual machine generally includes the file of two qcow2 mirror-image format, i.e. basis mirror image and increment mirror image, data in the mirror image of basis are generally a read states, data in increment mirror image are generally can be read to write state, increment mirror image is mainly used in recording and stores user to the amendment of the data in the mirror image of basis, and the data that user writes in increment mirror image, virtual machine can work based on increment mirror image usually, can by user write data and to basis mirror image in data modify after data be stored in increment mirror image.
In enforcement, as shown in Figure 2, terminal can be provided with virtual machine application, for creating virtual machine. if user needs to create virtual machine, then can click the establishment virtual machine button in virtual machine application, terminal generates request to create, terminal can be previously stored with multiple bases mirror image, when terminal receives request to create, user can be pointed out to select a basic mirror image as the basic mirror image of virtual machine from the mirror image of above-mentioned multiple bases by virtual machine application, then, user is progressively guided to carry out subsequent operations, such as, the size of prompting user's input or selection this local disk of virtual machine, point out the position etc. that user selects virtual machine to install, thus complete the establishment process of virtual machine. after virtual machine creating completes, this local disk of virtual machine comprises a basic mirror image and an increment mirror image (i.e. the first increment mirror image), and user can install some software for virtual machine, and corresponding data can be stored in the first increment mirror image. in order to allow the virtual machine can quick-recovery soon when there is fault, or can the virtual machine of the multiple identical configuration of fast creation, the first increment mirror image in virtual machine can be backed up, specifically, terminal can be provided with to the backup application that the increment mirror image in virtual machine backs up, in order to strengthen the experience of user, can the backup function of backup application be incorporated in virtual machine application, the backup function that the embodiment of the present invention incorporates backup application in virtual machine application is described in detail, for the treating processes using backup application to be backed up by the increment mirror image in virtual machine similarly, do not repeat them here, concrete treating processes can be: if user needs to be backed up by the first increment mirror image in current virtual machine (i.e. target virtual machine), then can click backup button, terminal demonstration information input frame, user can input data to be filtered mark in information input frame, such as the title or numbering etc. of data to be filtered, wherein, the data of data to be filtered mark correspondence can be the daily record class data etc. stored in target virtual machine, after having inputted, user can click and determine button, now, terminal can obtain the data to be filtered mark that user inputs in information input frame, generate the backup request of the first increment mirror image of corresponding target virtual machine, terminal can receive this backup request.
Step 102, creates the 2nd increment mirror image, other data except the data corresponding except data to be filtered mark in the first increment mirror image is copied in the 2nd increment mirror image.
Wherein, the basic mirror image that the first increment mirror image is corresponding with the 2nd increment mirror image is identical.
In enforcement, when terminal receives backup request, a blank increment mirror image (i.e. the 2nd increment mirror image) can be created by virtual machine application, first increment mirror image can be previously stored with data and the corresponding relation of data mark, then, terminal can be searched in the above-mentioned corresponding relation of the first increment mirrored storage, obtain the data that data to be filtered mark is corresponding, the data obtained can be marked by terminal, unmarked data are copied in the 2nd increment mirror image, now, 2nd increment mirror image stores other data except the data corresponding except data to be filtered mark in the first increment mirror image.
Can selection of land, the processing mode of above-mentioned steps 102 can be varied, below provide three kinds of optional processing modes, specifically can comprise following three kinds of modes:
Mode one, if target virtual machine is current not based on the first increment mirror image work, then create the 2nd increment mirror image, undertaken the first increment mirror image and the 2nd increment mirror image hanging load, other data except the data corresponding except data to be filtered mark in first increment mirror image are copied in the 2nd increment mirror image, cancels the extension to the 2nd increment mirror image and carry.
Wherein, hang during load refers to and be articulated in terminal by the increment mirror image in virtual machine certain catalogue already present, such as, in the catalogue of the hard disk in terminal.
In enforcement, when terminal receives backup request, terminal can detect target virtual machine currently whether based on the first increment mirror image work, if terminal determines that target virtual machine is not currently in startup state, or target virtual machine currently works based on other increment mirror image except the first increment mirror image, then terminal can create the 2nd increment mirror image by virtual machine application, wherein, 2nd increment mirror image can be blank increment mirror image, owing to virtual machine application does not arrange the function that the data in certain increment mirror image copy another increment mirror image usually, therefore, in order to achieve the above object, first increment mirror image and the 2nd increment mirror image can be hung load by terminal, now, the catalogue of the hard disk in terminal will increase the icon of two hard disks, like this, data in first increment mirror image and the 2nd increment mirror image can be carried out read-write operation by terminal, then, other data except the data corresponding except data to be filtered mark in first increment mirror image can be copied in the 2nd increment mirror image by terminal, after duplication completes, 2nd increment mirror image can be unloaded by terminal from the catalogue of above-mentioned hard disk, now, in the catalogue of hard disk, the icon of the hard disk that the 2nd increment mirror image is corresponding disappears. first increment mirror image can also be unloaded by terminal from the catalogue of above-mentioned hard disk, now, in the catalogue of hard disk the hard disk that the first increment mirror image is corresponding icon disappear, like this, it is possible to make target virtual machine follow-up can based on first increment mirror image work.
Mode two, if target virtual machine is currently based on the first increment mirror image work, then creates the snapshot image of corresponding first increment mirror image, the data in the first increment mirror image is copied in snapshot image, and snapshot image is set to the 3rd increment mirror image; Create the 2nd increment mirror image, undertaken the first increment mirror image and the 2nd increment mirror image hanging load, other data except the data corresponding except data to be filtered mark in the first increment mirror image are copied in the 2nd increment mirror image, cancels the extension to the 2nd increment mirror image and carry.
Wherein, snapshot image is the mirror image of a kind of mirror image based on certain increment mirror image, stores the data after the data in this increment mirror image being modified and the new data etc. of user's write in snapshot image.
In enforcement, if terminal detects that target virtual machine is in working order, and be based on the first increment mirror image work, then terminal can create the snapshot image of the first increment mirror image by virtual machine application, now, target virtual machine turns into working based on snapshot image from based on the first increment mirror image work, then, snapshot image can be set to increment mirror image by terminal, specifically, owing to target virtual machine currently works based on snapshot image, therefore the data in the first increment mirror image and snapshot image can be carried out read-write operation by target virtual machine, like this, data in first increment mirror image can be copied in snapshot image by target virtual machine by terminal, after duplication completes, snapshot image can be revised as the 3rd increment mirror image by terminal, the basic mirror image that 3rd increment mirror image is corresponding with the first increment mirror image is identical.
Terminal can create an increment mirror image (i.e. the 2nd increment mirror image) by virtual machine application, wherein, 2nd increment mirror image can be a blank increment mirror image, then, in the catalogue that first increment mirror image and the 2nd increment mirror image can be mounted in terminal hard disk by terminal, now, data in first increment mirror image and the 2nd increment mirror image can be carried out read-write operation by terminal, like this, other data except the data corresponding except data to be filtered mark in first increment mirror image can be copied in the 2nd increment mirror image by terminal, after duplication completes, 2nd increment mirror image can be unloaded by terminal from the catalogue of above-mentioned hard disk, first increment mirror image can also be unloaded by terminal, space is taken in order to save disk, first increment mirror image can be deleted by user.
Mode three, if target virtual machine is currently based on the first increment mirror image work, then create the snapshot image of corresponding first increment mirror image, first increment mirror image is carried out read-only extension load, and undertaken the 2nd increment mirror image hanging load, other data except the data corresponding except data to be filtered mark in first increment mirror image are copied in the 2nd increment mirror image, cancels the extension to the 2nd increment mirror image and carry; Cancel snapshot image.
Wherein, virtual machine application can be provided with two kinds and hang load mode, such as read-only extension load and extension load. When read-only extension load can be carry out increment mirror image hanging load, terminal can only read the data in increment mirror image, but the data in increment mirror image can not be revised or write data in increment mirror image, carry out the increment mirror image that the virtual machine that the read-only increment mirror image hanging load can be corresponding is using. When extension load can be carry out increment mirror image hanging load, the data in increment mirror image can be carried out read-write operation by terminal, and the increment mirror image carrying out hanging load is generally the increment mirror image not being in using state.
In enforcement, if target virtual machine is currently based on the first increment mirror image work, then terminal can create the snapshot image of the first increment mirror image, now, target virtual machine turns into working based on snapshot image from based on the first increment mirror image work, first increment mirror image is the basic mirror image of snapshot image, data wherein are used by target virtual machine, now, save disk and take space, first increment mirror image can be carried out read-only extension load, simultaneously, can carry out the 2nd increment mirror image hanging load, then, other data except the data corresponding except data to be filtered mark in first increment mirror image can be copied in the 2nd increment mirror image by terminal, after duplication completes, 2nd increment mirror image can be unloaded by terminal, now, first increment mirror image can also be unloaded by terminal, after completing said process, terminal can cancel snapshot image by virtual machine application, specifically, data in first increment mirror image can be copied in snapshot image by terminal, and snapshot image is set to the 3rd increment mirror image, now, target virtual machine works based on the 3rd increment mirror image.
Terminal can not also carry out the process of the cancellation snapshot image in aforesaid way three, then the processing mode of above-mentioned steps 102 can also comprise: if target virtual machine is currently based on the first increment mirror image work, then create the snapshot image of corresponding first increment mirror image, first increment mirror image is carried out read-only extension load, and undertaken the 2nd increment mirror image hanging load, other data except the data corresponding except data to be filtered mark in first increment mirror image are copied in the 2nd increment mirror image, cancels the extension to the 2nd increment mirror image and carry.
The treating processes of above-mentioned steps 102 is except aforesaid way, other modes can also be comprised, such as, terminal can create the snapshot image of corresponding first increment mirror image, data in first increment mirror image are copied in snapshot image, and snapshot image is set to the 3rd increment mirror image, then, can be undertaken the first increment mirror image hanging load, delete the data that the mark of the data to be filtered in the first increment mirror image is corresponding, cancel the extension to the first increment mirror image to carry, treating processes follow-up accordingly can be: the data in the first increment mirror image can be backed up by terminal, by the Backup Data that the backup data store obtained is the first increment mirror image, due to the characteristic of qcow2 mirror-image format, although above-mentioned treatment process deletes some data, but the disk space that the data in the first increment mirror image take does not reduce, for aforesaid way, the disk space that first increment mirror image takies can also be carried out capacity reducing by virtual machine application by terminal, thus reach the effect identical with above-mentioned three kinds of modes.
Data in 2nd increment mirror image are backed up by step 103, are the Backup Data of the first increment mirror image by the backup data store obtained.
In enforcement, terminal can obtain the data in the 2nd increment mirror image, and these data are backed up, obtain Backup Data, user can pre-set the storage address of a Backup Data, after terminal obtains Backup Data, it is possible to by this backup data store in storage area corresponding to above-mentioned storage address.
Can selection of land, backup services device can be set for backup process, corresponding data can be backed up and store by backup services device, accordingly, the treating processes of above-mentioned steps 103 can comprise following content: the backup messages sending the mark carrying data in the 2nd increment mirror image and the first increment mirror image to backup services device, so that the Backup Data of the data in the 2nd increment mirror image as the first increment mirror image is stored by backup services device.
In enforcement, terminal can obtain the mark (title etc. such as the first increment mirror image) of the data in the 2nd increment mirror image and the first increment mirror image, generate backup messages, it is sent to backup services device, when backup services device receives backup messages, it is possible to extracting mark and the data of the first increment mirror image wherein, backup services device can by this mark and this data corresponding stored, thus, backup services device stores the Backup Data of the first increment mirror image. Backup services device can also obtain the mark of basic mirror image corresponding to the first increment mirror image, then, it is possible to is stored by the Backup Data of the data in the data in the basic mirror image of correspondence and the 2nd increment mirror image as target virtual machine.
In the embodiment of the present invention, receive the backup request of the first increment mirror image of corresponding target virtual machine, backup request carries data to be filtered mark, create the 2nd increment mirror image, other data except the data corresponding except data to be filtered mark in first increment mirror image are copied in the 2nd increment mirror image, data in 2nd increment mirror image are backed up, by the Backup Data that the backup data store obtained is the first increment mirror image, like this, by creating blank increment mirror image, with other data except the data of data to be filtered mark correspondence stored in the first increment mirror image, and then reach the object backed up by specific data, thus, the handiness of data backup can be improved.
