User can adjust the permissions data corresponding to the terminal in server by terminal, be visited so as to adjust the terminal
Ask the permission of gateway device.
Fig. 8 shows the structure chart of data management system according to an embodiment of the invention.
As shown in figure 8, data management system 400 according to an embodiment of the invention can specifically include：Management server
810（It is equivalent to server 200）, gateway 808（It is equivalent to gateway device 100）And terminal 802, terminal 804 and terminal
806（It is respectively equivalent to terminal 300）.Terminal can be established by Internet and gateway 808 and be connected, can also directly and net
It closes 808 and establishes connection.
Particular flow sheet is as shown in Figure 9：
Terminal 804 first by file or data f1 storage to gateway 808, press by time of the gateway 808 according to f1, size
Divided and stored according to default storage cell, is then established with the relevant storage information of f1.Long-range management server 810 is awarded
Power terminal 802 and terminal 806 data in gateway 808 are read out and are changed, can also be arranged as required to limitation read or
The operation that person writes.When gateway 808 judges that terminal 802 and terminal 806 have reading and change the permission of data in gateway 808, permit
Perhaps terminal 802 calls f1 to be operated, meanwhile, gateway 808 is automatically divided the parts changed f1 according to default storage cell
Increment preservation is cut and carries out, every piece of storage data can be accurate to second grade by this.Possess equal to the terminal of 808 operating right of gateway
Can open special time period or particular moment according to f1（Including the incremental data after f1 after original f1 and modification）, and still
The f1 at a certain moment can be directed to be operated, to ensure that gateway 808 stores the trackability of data.
Divide n part, i.e. f1 in seconds（T1, t2 ... tn）, then when terminal 806 is right
Tn in f1 is operated, and continues m seconds, then the incremental portion that gateway preserved a tn by each second, i.e. f1 [t（n+1）, t（n
+2）…t（n+m）], to be preserved the data at each moment, further, user can also be preserved to incremental number
According to the new increment data after being operated accurate nothing is provided to be preserved at each moment to every partial data
That misses can trace back data.
Gateway 808 stores time for being subject in gateway 808 time of data, and the time of gateway 808 is always and pipe
The time for managing server 810 keeps synchronizing, and to ensure that data are stored in temporal consistency, management server 810 is also
DNS management can be carried out to gateway 808.
Technical scheme of the present invention is described in detail above in association with attached drawing, it is contemplated that in the related technology, pass through home gateway
Memory when carrying out shared storage and lasting backup with preserving to file and data, it is difficult to ensure the data and file of storage
Consistency and trackability.Technical solution through the invention can be protected when storing data and/or file by gateway
Demonstrate,prove data and/or the consistency and trackability of file.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
