Abstract
The invention discloses a method and system for detecting a cloud storage data collision. The method comprises the steps that changes of data files in a synchronize folder is monitored, and an inquire request is sent to a data collision detection server; information, fed back by the data collision detection server, of other online users is received, and according to the information of other online users, a data collision detection request is sent to the other online users, after data information fed back by the other online users is received, data collision detection is conducted, and a data collision detection result is sent to the data collision detection server. The method solves the problem that no positive detection measures are taken for data collision currently, and achieves the purpose that the data uniformity condition of different terminals is checked in time.
Description
Technical field
The present invention relates to the Internet and field of cloud calculation, particularly relate to a kind of cloud and store data collision detection method and system.
Background technology
Cloud stores service makes the Internet user of today easily and reliably to access and sharing data.No matter user in when and where, use what terminal equipment, as PC, panel computer or smart mobile phone etc., the data deposited beyond the clouds, as document, picture, music or video etc., can be automatically synchronized to the online equipment of this users all and other sharing users.That is, cloud stores service provides the pervasive access of electronic data, and the data movement that user does can be automatically fed to high in the clouds and is pushed to relevant device further by high in the clouds, thus greatly simplifies striding equipment management and the consistency maintenance of data.
Along with the fast development of computing technique and the increase of Internet bandwidth, the high in the clouds of electronic data stores and finally becomes possibility recent years with pervasive access, creates a collection of representative cloud stores service as the OneDrive (being called SkyDrive before in February, 2014) of Dropbox, Microsoft, Google Drive, UbuntuOne of Google and Kingsoft fast disk, Baidu's cloud dish, 360 cloud dishes, 115 net dishes, the micro-dish of Sina and cruel dish etc.In these services, only Dropbox mono-just has close to 300,000,000 users, average daily newly-increased and renewal more than 1,000,000,000 files, OneDrive, Google Drive supported by conventional internet giant in addition, Baidu's cloud dish and 360 cloud dishes etc. then every all had hundred million users.Above-mentioned statistics does not also comprise a series of derivative service depending on cloud stores service.
As one of the key technology of cloud stores service, data syn-chronization operation by a series of network service behavior and local computing behavior, the data movement that user side occurs is automatically mapped to high in the clouds, for the need for reliable backup of data provides solid and supports easily with sharing flexibly.Fig. 1 is the principle schematic that prior art cloud stores data syn-chronization, as shown in Figure 1, in a cloud stores service, the file that user needs appointment one special usually, be called synchronization folder, and corresponding cloud storage client software be installed, any data movement occurred in synchronization folder, as document creation, file erase, file modification etc., all cloud storage server can be synchronized to by client control.Specifically, data synchronization process relates to a series of network service behavior and local computing behavior, the former comprises transmission data directory, data content, synchronization notice, synchronous regime and statistical information, confirmation of synchronization etc., and the latter comprises data cutting, hash calculating, comparing etc.In this process, in order to ensure data can carry out between other equipment synchronously with share, collision detection is carried out to the data on each equipment and just seems very important with the data consistent implementations obtained on each equipment.Along with the expansion of cloud stores service, service scenarios is as the appearance of cooperated documents editor, Database vendors etc., other common causes in unstable networks or synchronizing process will have a strong impact on the service experience of user as the generation of the situation such as sync break, synchronization delay, even affect the normal scientific research of user, working and learning.With Dro
pbox is example, when two users edit a Scientific Articles jointly, party A-subscriber's edited result is preserved, but be not still synchronized to party B-subscriber after being separated by 24 hours, at this moment, between party A-subscriber and party B-subscriber, there is data collision, owing to failing to obtain in time the data consistent implementations of party A-subscriber and party B-subscriber, just can not upgrade in time the data of party B-subscriber, and this has just had a strong impact on scientific research progress, causes unnecessary loss.

The cloud that Figure 11 provides for the embodiment of the present invention nine stores the principle schematic that data collision detection system carries out data collision detection.As shown in figure 11, by being configured in the data file variation in the data collision detection software supervision local synchronization file of user side, and send inquiry request, now other online user's client informations in data collision detection server return data storehouse to data collision detection server.The data collision detection software of user side sets up end to end connection between user side according to return information by the network port, performs data collision detection operation.If user side collision detection software supervision is to the collision detection request of other user sides, then return the data file transition information in local synchronization file.Result is sent to data collision detection server so that user is checked by browser by user side after data collision detection end of operation, if when there are not other online users in data collision detection discovering server, or, when all there is data collision in user and every other online user, then send data collision detection request carry out data collision detection to cloud storage server, and result is kept at data collision detection server database and consults for user.
The cloud provided in the embodiment of the present invention nine stores data collision detection system, by the data file variation in the synchronization folder of collision detection software supervision user side, inquiry request is sent to data collision detection server, end to end connection is set up one by one according to other user side information lists that data collision detection server returns, obtain colliding data result and the list of inactive users end, and these information are sent to data collision detection server, consult data collision detection result to make user.Solve the problem not taking any front detection method at present for data collision problem, achieve the data consistent implementations of inquiring about in time on each different terminals, improve Consumer's Experience.
The know-why that above are only preferred embodiment of the present invention and use.The invention is not restricted to specific embodiment described here, the various significant changes can carried out for a person skilled in the art, readjust and substitute all can not depart from protection scope of the present invention.Therefore, although be described in further detail invention has been by above embodiment, the present invention is not limited only to above embodiment, when not departing from the present invention's design, can also comprise other Equivalent embodiments more, and scope of the present invention is determined by the scope of claim.
