Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are elaborated.
As shown in Figure 1, for according to a kind of cloud backup method process flow diagram for terminal program described in the embodiment of the present invention, comprise the steps:
Step 101: the preset document data bank of server beyond the clouds, store the core document that distinct program comprises, and the uniqueness identification information of described core document;
Step 102: obtain the uniqueness identification information of core document of the program of wish backup in end side, and be sent to cloud server back-up storage;
Step 103: described cloud server is determined the corresponding relation between the backup terminal/subscriber of described uniqueness identification information and the core document of described uniqueness identification information representative according to described document data bank.
The concept of cloud server, sizable development and utilization have been obtained at present, for example, foundation for virus characteristic storehouse, can be arranged at cloud server, client only need to upload local file feature can with cloud server in virus characteristic compare, thereby use blacklist killing virus.
In like manner, embodiments of the invention are a preset document data bank in server beyond the clouds, stores the core document of the program of different classes of different editions, and the uniqueness identification information of core document.
By long-term accumulation, server can be set up a huge document data bank that comprises numerous common programs files beyond the clouds, and for example some conventional operating systems and application program that some are conventional can be included in wherein.
And by actual analysis, be the scope that can know its original core document of various programs.Described core document can be the original document that this program discharges after installation in terminal; Or those maintain the requisite master file of this program operation; Or also can refer to that those same programs are installed in different terminals and move the general character file that still keeps same content after a period of time.
The scope of core document is selected, and can determine according to distinct program and different backup requests.Obviously, the scope of the core document of backup is larger, the also sample state during backup of more faithful to terminal of the program after reduction; And the scope of the core document of backup is less, the data volume of backup is less, and the program after reduction more approaches the initial sample state of this program after installation.But clearly, those some garbage files that may produce after program is moved a period of time or can be comprised in core document by some harmful files that rogue program injected such as viruses.
Concerning running on the same program in different terminals, the content major part of its core document is identical, and the file being damaged is minority after all, and therefore, this just provides the foundation for multiplexing high in the clouds file data library file.
In document data bank in cloud server, store the core document that distinct program comprises, and the uniqueness identification information of described core document.The MD5 value that the signing messages that described uniqueness identification information can be this document or calculating obtain etc.
The core document comprising due to the same program running in terminal, if do not have destroyedly, its signing messages is to be consistent with the signing messages of this core document in the database of high in the clouds.Therefore, the signing messages of this core document of this program in terminal is stored in to server side, just can plays this core document is backed up in the identical object of server side, because there is the identical core document of same signature information, be pre-stored in database and suffered.Only for the inconsistent core document of those signing messages, storage in just need to uploading onto the server by this end side is actual.
So, the uniqueness identification information that this terminal only need to be uploaded the core document of this stand-by program has just completed back-up job, and cloud server can determine which the core document of this terminal backup is according to this uniqueness identification information.
As shown in Figure 2, in terminal 201, comprise program 1, program 2 and program 3, its Program 1 is the program of wish backup, it includes core document 1, core document 2, core document 3, and garbage files 4, corresponding uniqueness signing messages is file signature 1, file signature 2 and file signature 3, and file signature 4.In server 202 data-base recording the core document 1 of program 1, core document 2 and core document 3, corresponding uniqueness signing messages is file signature 1, file signature 2 and file signature 3.And in the content of server side backup, only need to record file signature 1, file signature 2 and the file signature 3 of the program 1 of this terminal or user ID 201 and backup.Clearly, the data content of terminal backup seldom, but is enough to determine at server side the routine data that this terminal need to back up.And, due to backup be all the core document of program, some possible garbage files are foreclosed, this has not only reduced backup data quantity, and after recovery, can reduce a clean program.
Described end side can be according to the core document title of this wish stand-by program recording in a preset rule list, obtains the uniqueness identification information of core document of the program of wish backup.This rule list can be that end side carries, the original document that this program for example recording in end side when this program is carried out installation discharges; Or by the list of end of scan local program, according to program name and version, to server end, ask for, server end stores the core document rule list of numerous common programs.Can pass through the range size of the flexible control core file of this rule list.
In addition, can also directly utilize the document data bank described in the embodiment of the present invention to determine core document, as shown in Figure 3, for according to obtaining the process flow diagram of uniqueness identification information of core document of the program of wish backup in end side described in the embodiment of the present invention, comprise:
Step 301: end side is sent to cloud server by the uniqueness attribute information of the program of wish backup;
Step 302: described cloud server determines according to the uniqueness attribute information of the distinct program of document data bank record the core document that this program and institute's correspondence thereof comprise, and the title of core document is sent to this end side;
Step 303: described end side is according to the uniqueness identification information of the core document of the program of the name acquiring wish backup of described core document.
The title that wherein said uniqueness attribute information can be this program and version number or program ID etc. can be unique the information of determining this program object.
According to embodiments of the invention, if described cloud server cannot be determined core document corresponding to uniqueness identification information sending with described end side in described document data bank, illustrate that the signing messages of this core document of end side and the signing messages of this core document in server side database are inconsistent, it is likely the personality file of having been revised by user, at this moment can the local core document corresponding with this uniqueness identification information be sent to cloud server back-up storage by described end side.
In addition, can also define the non-core file of some these programs, for example record the file to the static configuration of this program, or the file of user data, because although these files do not affect the operation of program, but may record user's use habit, therefore, also can when backup, extract.Like this, can be obtained by described end side the current non-core file of the program of described wish backup, and be sent to cloud server back-up storage.Or the uniqueness identification information that further obtains non-core file is back-up storage in the lump.The definite form that can take equally rule list of non-core file.
For some software programs, in its installation process, may modify to the registration table of current operation system, therefore, when backup, the modification item of the program that can obtain the backup of described wish by described end side in registration table, and be sent to cloud server back-up storage, to registration table is reduced while recovering.
For most program, its file discharging after installing can be all under same directory path, that is to say that its relative position relation is unimportant, but for some comparatively complicated programs, operating system program for example, may be nested with the situation of multilayer catalogue, at this moment the relative position relation information between core document can be stored in document data bank; Also can be by described end side, the relative position relation information between the core document of described wish stand-by program to be sent to cloud server to store.
Equally, concerning non-core file, end side also can be sent to the relative position relation between current core document and non-core file cloud server storage.
As shown in Figure 4, for according to a kind of cloud restoration methods process flow diagram for terminal program described in embodiments of the invention, comprising:
Step 401: according to the recovery request of terminal/subscriber, described cloud server is determined the uniqueness identification information of the core document corresponding to described program that this terminal/subscriber has backed up;
Step 402: the uniqueness identification information of the core document of this program that cloud server side has been backed up mates with the current uniqueness identification information of the file of the local corresponding program of this end side;
Step 403: in end side, file corresponding to the unsuccessful current uniqueness identification information of coupling deleted, and by cloud server side, file corresponding to the unsuccessful uniqueness identification information of coupling is sent to this end side corresponding stored,
Wherein, described cloud server presets a document data bank, stores the core document that distinct program comprises, and the uniqueness identification information of described core document.
Cloud server just can be known active user according to the user login information of end side, also just can know the data that this user once backed up.For most of terminal/subscriber, after receiving its recovery request, server just can be determined the uniqueness identification information that this user ID is crossed.As shown in Figure 2, core document in the signing messages-database recording in core document signing messages-high in the clouds document data bank of user terminal-stand-by program-end side core document and signing messages thereof-back up, these corresponding relations are all linked to each other by uniqueness identification information.
When recovering, the uniqueness identification information of the core document of this program that cloud server side can have been backed up mates with the current uniqueness identification information of all files of the local corresponding program of this end side.So, end side does not need to determine the scope of core document, every and the inconsistent local program file of signing messages that backed up all can be deleted, comprise more local garbage files relevant with this program and because file is impaired or revise after cause the file of signing messages variation; And at server side, the signing messages the having backed up representative that can successfully mate is excellent in end side respective file, and the signing messages of backup that cannot successfully mate represents that end side original has changed, this just need to utilize the respective file in document data bank to be sent to end side storage.Because this original having changed is because cannot successfully mate and deleted, therefore, the respective file in database is just sent to end side and has replaced original.Due to visible, the reset mode of the embodiment of the present invention is right based on aspect ratio, the file that only has signing messages to change just needs reality to be sent to terminal from server, this with regard to very big reduction volume of transmitted data, and deleted the garbage files that end side produces in program operation process, improved terminal program performance.
When recovering, can also be that the uniqueness identification information of the core document of this program that cloud server side has been backed up mates with the current uniqueness identification information of the core document of this corresponding program in end side this locality.
And the step of mating for the uniqueness identification information between core document can be to be carried out by end side, can be also to be carried out by server side.
For example, can the uniqueness identification information of the core document of described stand-by program be sent to end side by cloud server; Then, end side is mated the uniqueness identification information of the core document of the stand-by program receiving with the current uniqueness identification information of the core document of local corresponding program.
Or the current uniqueness identification information of the core document of the program of wish being recovered by end side is sent to cloud server; Then, by described cloud server, the described current uniqueness identification information of receiving is mated with the uniqueness identification information of the core document of this program having been backed up by this terminal of storage.
The coupling of only carrying out between core document can reduce the scope of end side deleted file, thereby can retain more accurately end side personality file, and the reduction of inclusive NAND core document complements one another.
If also back up non-core file at server side, the non-core file of this program that can further by cloud server, end side have been backed up is sent to end side corresponding stored.
If cloud server backed up non-core file with and corresponding uniqueness identification information, the uniqueness identification information of the non-core file of this program that cloud server side can have been backed up mates with the current uniqueness identification information of the file of the local corresponding program of this end side, if coupling is consistent, supporting paper is intact, do not need to replace, if mate inconsistent, end side can be mated to unsuccessful non-core file and delete, and the more unsuccessful non-core file of coupling of server side backup is sent to end side corresponding stored.
If cloud server has backed up the Registry Modifications item of this program, this program that can also this terminal have been backed up by cloud server is sent to described end side to the modification item of registration table, and according to this modification item, local registration table is carried out to corresponding modification by this terminal.
And for program file the store path in end side, can store according to Default installation path, also can know that this program is at the installation path of end side by News Search technology, in fact, generally as long as end side has a core document just can know the installation path of this program.
In addition, described end side can also be stored core document according to the relative position relation between the described core document of server record beyond the clouds; Or according to the described non-core file of server record and the relative position relation between core document are stored non-core file beyond the clouds.
At some in particular cases, if do not find described corresponding program in described terminal this locality, illustrate that this program may be deleted, at this moment core document corresponding with the uniqueness identification information having backed up in described cloud server can be sent to this end side corresponding stored.
In addition when recovering, if end side need to be known the core document scope of this program, be to determine according to a presetting rule table title of the core document of the corresponding program in described this locality equally; Or determine described local corresponding core document title according to the core document title of the described program recording in the document data bank in described cloud server.
As can be seen here, the present invention is owing to only needing the signature identification of the core document of stand-by program in when backup, and need not actual backup file content, and therefore, backup rate is very fast, and the data volume of transmission greatly reduces; Meanwhile, during recovery, be based on diversity ratio recovery, if the signature identification of core document does not change, do not need to recover this document, that only has that signature identification changes just need to download corresponding document from database, therefore, the speed of recovering is also very fast, and transmission quantity seldom.Meanwhile, owing to being based on diversity ratio recovery, therefore, harmful files such as garbage files that the file extent during with backup or content there are differences can be eliminated, and have promoted program feature after recovery.
