Abstract
The invention provides a data synchronization method. The data synchronization method comprises the steps that a local encryption space is marked out from a local storage space according to settings of a user; storage data in the local encryption space is obtained, and flag data corresponding to the storage data is set in the local encryption space, wherein the storage data includes content bits, and the flag data includes flag bits corresponding to the content bits in a one-to-one mode; when the content bits of the storage data are modified, the flag bits in the flag data are modified in a predetermined mode; the flag data is scanned, and if it is found that the flag bits are modified, the contents corresponding to the content bits are encrypted according to the modified flag bits; the encrypted contents are synchronously stored to other at least one storage device. In the mode, the data synchronization method can ensure the real-timeliness and consistency of data synchronization, and meanwhile the data processing quantity is decreased.
Description
Technical field
The present invention relates to areas of information technology, particularly relate to a kind of method of data synchronization.
Background technology
Data syn-chronization is the important technology of data process aspect, is especially applied in the occasion needing to back up in realtime. There are two problems in current data syn-chronization: one is rely on other intermediate systems so that synchro system is excessively complicated, causes that system is unstable. Time BUG occurs in system, the debugging quantities of system is big, and time efficiency is low; Two is rely on complex technology to ensure real-time and the concordance of data. Technology is excessively complicated, it is difficult to co mpiler optimization generates efficient object code. Executing efficiency is low, and code refactoring time cost is high, and programming process is not cost-effective.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of method of data synchronization, it is possible to ensures real-time and the concordance of data syn-chronization, reduces data processing amount simultaneously.
For solving above-mentioned technical problem, the technical scheme that the present invention adopts is: provide a kind of method of data synchronization, including: from locally stored space, mark off local cipher space according to the setting of user; Obtain the storage data in described local cipher space, and the flag data corresponding with described storage data is set in described local cipher space, wherein, described storage data include content position, and described flag data includes and described content position marker bit one to one; When the content position of described storage data is modified, described flag data is revised marker bit in a predefined manner; Scan described flag data, if it find that marker bit is modified, according to the described marker bit that amendment occurs, the content of corresponding content position is encrypted; The content synchronization of described encryption is stored other at least one storage devices.
It is different from the situation of prior art, the invention has the beneficial effects as follows: by using marker bit that amended storage data are carried out labelling, when synchrodata, storage data that sync mark position is modified, it is thus possible to ensure real-time and the concordance of data syn-chronization, reduce data processing amount, it is possible to improve the efficiency of data syn-chronization simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of embodiment of the present invention method of data synchronization.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Referring to Fig. 1, it it is the schematic flow sheet of embodiment of the present invention method of data synchronization. The method of data synchronization of the present embodiment includes:
S1: mark off local cipher space from locally stored space according to the setting of user.
Wherein, in locally stored space, mark off part memory space as local cipher space according to user setup, add ciphertext data for what deposit this locality. Such as, user goes out local cipher space by new folder model split that this new folder is encrypted.
S2: obtain the storage data in local cipher space, and arrange the flag data corresponding with storage data in local cipher space, wherein, storage data include content position, and flag data includes and content position marker bit one to one.
Wherein, flag data can be that some simply encode, and data volume is only small, the mode one_to_one corresponding that can be mapped by address between marker bit and the content position of storage data of flag data, further, if storage data have newly-increased content position, then flag data also can increase marker bit accordingly.
S3: when the content position storing data is modified, revise marker bit in flag data in a predefined manner.
Wherein, after marker bit is revised in a predefined manner, it is possible to reflect that the content position that this marker bit is corresponding is revised.
S4: passing marker data, if it find that marker bit is modified, the content of corresponding content position is encrypted by the marker bit according to there is amendment.
Wherein, can adopting multiple cipher mode in the present embodiment, the present embodiment does not limit concrete cipher mode. Data encryption can actively strengthen safety during data synchronization transmissions.
S5: the content synchronization of encryption is stored other at least one storage devices.
Wherein, the present available capacity of other storage device should more than encryption content required for memory capacity. In the present embodiment, the present available capacity of storage device can be prejudged whether more than the memory capacity required for the content of encryption, when the present available capacity confirming storage device is enough, then start to carry out synchronizing storage to this storage device.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the present invention and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in the scope of patent protection of the present invention.
