Specific implementation mode
In practical application scene, user terminal may hold the data file in user terminal under the instruction of user The corresponding operation of row (such as peace loading, unloading, establishment, modification or deletion), therefore, can for the ease of being managed to data file The operation of each data file will be recorded, and backs up newest data file.
The scheme of the embodiment of the present invention records the operation of data file user terminal, by the same data text of correspondence Part file operation record carry out merging, and by the file operation of each data file record be uploaded to server carry out it is standby Part, to which server understand which kind of operation user terminal carried out to data file, and it is extensive in user terminal progress data User terminal is instructed to carry out intelligent restoration when multiple.
Embodiments of the present invention is further illustrated with reference to the accompanying drawings of the specification, but the present invention is not limited to following reality Apply example.
Embodiment one：
As shown in Figure 1, data back up method includes the following steps in the embodiment of the present invention one：
Step 101：User terminal generates the file corresponding to each data file according to the operation to each data file respectively Operation note；
Step 102：The file operation record of the same data file of correspondence is carried out merging by user terminal；
Step 103：The file operation record of each data file is uploaded to server by user terminal.
Wherein, include the operational order that corresponding operating is executed to corresponding data file in file operation record.For example, false If user terminal at a time performs installation operation to a data file, then a provision of the Generating Data File is directed to It is instructed comprising installation operation in part operation note.
Preferably, it is directed to a data file, if the data file is application program installation kit, the data file When may include file name, store path, installation path, operational order and the operation of the data file in file operation record Between；It, should if the data file is general data file (such as text file, video file are not required to data file to be mounted) When may include file name, store path, operational order and the operation of the data file in the file operation record of data file Between.
For example, it is assumed that when 8 days 14 May in 2014 32 divide be mounted in user terminal within 53 seconds a file name be " wechat " Application software, then user terminal for the application software generate a file operation note：
File name：Wechat, store path：/ sdcard/data/app, installation path：/ sdcard/instal/app, Operational order：Installation, operating time：32 divide 53 seconds when 8 days 14 May in 2014.
In another example, it is assumed that when 8 days 14 May in 2014 36 divide created in user terminal within 53 seconds a file name be " meeting The document of view summary ", then user terminal is for the document one file operation note of generation：
File name：Meeting summary, store path：/ sdcard/data/file, operational order：It creates, the operating time： 36 divide 53 seconds when 8 days 14 May in 2014.
For same data file, different operations may be carried out in different moments, therefore, it is necessary to will correspond to same number Merging is carried out according to the file operation record of file.Specifically, for a data file, if the data file is application Program installation kit, and the corresponding file operation record of the data file includes that installation operation instruction and unloading operation instruct, then User terminal deletes the corresponding each file operation record of the data file；If the data file is general data file, and should The corresponding file operation record of data file includes creating operational order and delete operation instruction, then user terminal deletes the number According to the corresponding each file operation record of file.
For example, it is assumed that file name currently stored in user terminal is corresponding two files of application software of " wechat " Operation note is respectively：
File operation record 1：
File name：Wechat, store path：/ sdcard/data/app, installation path：/ sdcard/instal/app, Operational order：Installation, operating time：32 divide 53 seconds when 8 days 14 May in 2014；
File operation record 2：
File name：Wechat, store path：/ sdcard/data/app, installation path：/ sdcard/instal/app, Operational order：Unloading, operating time：35 divide 53 seconds when 8 days 14 May in 2014.
Due to file name be " wechat " the corresponding two file operation notes of application software in contain installation operation Instruction and unloading operation instruction, user terminal delete file operation record 1 and file operation record 2.It should be noted that due to Unloading operation was executed to the application software, therefore, the application software is will be not present in user terminal.
In another example, it is assumed that currently stored file name is corresponding three provision of document of " meeting summary " in user terminal Part operation note is respectively：
File operation record 11：
File name：Meeting summary, store path：/ sdcard/data/file, operational order：It creates, the operating time： 36 divide 53 seconds when 8 days 14 May in 2014；
File operation record 12：
File name：Meeting summary, store path：/ sdcard/data/file, operational order：Modification, operating time： 37 divide 53 seconds when 8 days 14 May in 2014；
File operation record 13：
File name：Meeting summary, store path：/ sdcard/data/file, operational order：It deletes, the operating time： 38 divide 53 seconds when 8 days 14 May in 2014.
Since file name operates to contain establishment in the corresponding three file operation notes of document of " meeting summary " Instruction and delete operation instruction, user terminal delete file operation record 11~13.It should be noted that due to being held to the document Therefore delete operation of going will be not present the document in user terminal.
User terminal, can be by remaining text after the file operation record that will correspond to same data file carries out merging Part operation note is uploaded to server.During specific implementation, user terminal can record file operation and corresponding data File is uploaded to server together, if being stored with the data file in server, user terminal does not upload.
Distinguishingly, for a file operation note, if the corresponding data file of this document operation note is user terminal The data file downloaded from network side, then user terminal generates the file download record of the data file, and this document is downloaded Record is uploaded to server.
Wherein, the download address of corresponding data file is included in file download record, then server is receiving user After the file download record that terminal uploads, it can be downloaded and be corresponded to from network side according to the download address for including in this document Download History Data file.Wherein, download address is specifically as follows uniform resource locator (URL, Uniform Resource Locator it) links.
Preferably, also may include the downloading mode of corresponding data file in file download record, for example, Hyper text transfer Agreement (HTTP, Hypertext Transfer Protocol) downloading mode and text transfer protocol (FTP, File Transfer Protocol) downloading mode, then server, can root after the file download record for receiving user terminal uploads According to the download address and downloading mode for including in this document Download History corresponding data file is downloaded from network side.
Preferably, also may include the data volume and check value of corresponding data file in file download record, then server After the file download record for receiving user terminal uploads, it can first search in the database and include with this document Download History The data volume data file consistent with check value, if can find, by the data file found and the text received Part Download History and file operation record are associated；If do not found, under including in this document Download History Set address downloads corresponding data file from network side, and by the data file downloaded to and the file download received record and File operation record is associated.
Wherein, the data volume of data file is specially the size (such as 5 Mbytes) of data file, the check value of data file The hash value that Hash (Hash) is calculated specially is carried out to the content of data file.If server is remembered according to file download The download address for including in record downloads corresponding data file from network side, then after having downloaded data file, server can also According to the content of the data file generate hash value, and by the hash value of generation it is corresponding with the data file store.
Preferably, also may include the text of corresponding data file in the file download record that user terminal is uploaded to server Part title and store path, in this case, later stage user terminal when carrying out data recovery, data file can be stored in it is extensive Identical position before multiple.For example, it is assumed that before data are restored, user terminal has downloaded a file name from network side and has been The video file of " XX concerts ", and store it in/sdcard/data/video, then it is needed when user terminal breaks down When restoring data, also the video file that file name is " XX concerts " can be stored in/sdcard/data/video.
Preferably, if server is corresponding from network side download according to the download address for including in this document Download History Data file fails, then sends failed list to user terminal.User terminal receive server transmission failed list when, The data file of server failed download is uploaded to server.Specifically, server can will be from the number of network side failed download User terminal is sent in failed list according to file name and the store path carrying of file, then user terminal is by failed list In include file name and the corresponding data file of store path be uploaded to server.
Since the download address for the data file downloaded from network side in user terminal is uploaded to server, by server Download corresponding data file from network side according to the download address of user terminal uploads, to user terminal does not need will be from net The entire data file that network side is downloaded is uploaded to server, can greatly reduce the time of data backup, realize the number of user terminal According to the quick backup to server.
It is described above the process that the data file downloaded from network side in user terminal is backed up to server, for It is not the data file downloaded from network side, such as the data file that user terminal is obtained from other users terminal, due to service Device can not obtain the data file, which need to be directly uploaded to server and backed up by user terminal.
