The details will be described separately below.

In a preferred embodiment, the data backup device is integrated into an electronic device such as a terminal, and the terminal can be a device such as a mobile phone or a tablet computer.

As shown in Figure 2, a data backup method, the specific process is as follows:

101. Obtain the original data to be backed up.

Specifically, the data backup instruction may be received, and the original data to be backed up is obtained according to the data backup instruction. For example, the data to be backed up is copied according to the data backup instruction, the original data to be backed up is obtained, or the corresponding original data to be backed up is obtained from the local storage unit according to the data backup instruction, and the like.

The data backup instruction may be triggered by an event, for example, may be automatically triggered by a change in data. Specifically, when a certain data (such as a specified backup data) is detected, a data backup is triggered. The instruction, at this time, the data backup device can receive the data backup instruction. For example, when it is detected that the SMS message data of the specified backup changes (adds, deletes or changes), a trigger to send data backup instruction is issued. The data backup instruction can be automatically triggered by the system. For example, the data backup instruction is automatically triggered every preset time.

In addition, the data backup instruction may also be triggered by triggering a trigger interface such as a preset trigger key or an input box in the terminal, for example, when the user clicks or swipes a backup icon on the backup interface, the data backup instruction is triggered to be generated. At this time, the data backup device can receive the data backup instruction.

In the embodiment of the present invention, the types of data to be backed up may be various, for example, the original data to be backed up may be short message data, chat record data, call record data, or photo data, and the like. When the data change triggers the data backup, the original data to be backed up may be the changed data.

102. Cut the original data to be backed up into multiple data segments according to a preset cutting rule.

The preset cutting rule may be set according to actual requirements, such as cutting the original data to be backed up into data segments of equal size, and the like. The data segment is a data unit and can contain several data. Of course, in practical applications, the preset cutting rules are set based on the principle of reversibility. For example, the original backup data A is cut into a data segment a1, a data segment a2, a data segment a3, a data segment an.

Specifically, in order to improve data security, the embodiment may preset a plurality of cutting rules, so that a cutting may be selected for cutting when the data is cut, thereby making the cutting method used for each data backup different, which is improved. Data security; that is, the step of "cutting the original data to be backed up into multiple data segments according to a preset cutting rule" may include:

Selecting a preset cutting rule from a plurality of preset cutting rules;

Among them, the cutting rule can be selected in various ways, for example, a preset cutting rule can be randomly selected from a plurality of preset cutting rules, and the like.

For example, a cutting rule can be randomly selected from the cutting rule 1, the cutting rule 2, the cutting rule n.

103. Combine the plurality of data segments to obtain target to be backed up data that is different from the original data to be backed up.

For example, multiple data segments can be combined according to a preset combination. The preset combination mode is a combination of data segment splicing and combining. For example, the preset combination mode may include: splicing and combining according to the serial number of the data segment, splicing and combining according to the size of the data segment, and according to the data segment in the original data to be backed up. The position is spliced and the like, and the preset combination mode can be set according to actual needs.

In this embodiment, the data to be backed up is different from the original data to be backed up, and may be: the data format of the target to be backed up is different from the original data to be backed up, the data content is different, the data structure is different, the data size is different, or other data parameters are different.

For example, the data segment a1, the data segment a2, the data segment a3, and the data segment an may be recombined to obtain data to be backed up that is different from the original data A to be backed up. The data content of the original data to be backed up and the data B to be backed up are different, or the data format is different.

In order to improve data security, the embodiment may further set a plurality of combinations in advance so as to be selected when the candidate data is backed up, so that the combination mode used for each data backup is different, thereby improving data security; that is, steps. "Combining the plurality of data segments" may include:

Select a target combination method from a plurality of preset combinations;

The plurality of data segments are combined according to a target combination.

The combination mode may be selected in multiple ways, for example, according to time, location, data type, number of data segments, and other parameters; for example, it may also be randomly selected.

For example, one combination mode is randomly selected from the combination mode 1, the combination mode 2, the combination mode 3, the combination mode n as the target combination mode, and the like.

104. Back up the data to be backed up to the server.

Specifically, the target backup data may be sent to the server, so that the server backs up the target backup data.

For example, the data backup request carrying the data to be backed up may be sent to the server, so that the server backs up the data to be backed up according to the data backup request.

If the data to be backed up is too large, the efficiency of the data backup is reduced. Therefore, in order to improve the data backup efficiency, the embodiment can also cut the target standby data into several data segments, and then back up the data segment to the server. ; that is, the step of "backing up the target data to be backed up to the server" may include:

Cutting the target data to be backed up into multiple backup data segments;

Back up the multiple backup data segments to the server in turn.

For example, the data B to be backed up by the above recombination may be cut into a data segment b1, a data segment b2, a data segment b3, a data segment bm; then, the data segment b1 is backed up to the server, and then the data segment b2 is backed up to the server. Back up the data segment b3 to the server... Back up the data segment bm to the server.

Optionally, after the data is backed up to the server, if the backup data needs to be obtained from the server, then the combination combination method and the cutting rule are needed to restore the original original backup data, so that the user can obtain the real data by himself. That is, after step 104, the data backup method may further include:

Receiving backup data sent by the server;

The restored plurality of data segments are assembled according to the preset cutting rule to obtain original backup data.

Optionally, in order to enable the backup data acquisition terminal to know the combination mode and the cutting rule used in the data backup, the embodiment may further send the rule identifier of the cutting rule and the mode identifier of the combination mode to the server, so that the server sends the identifier. Give the data acquisition terminal. That is, after the step of "combining the plurality of data segments", the data backup method further includes:

The rule ID and mode ID are sent to the server.

For example, the identifier of the selected cutting rule 5 and the identifier of the combination mode 6 are sent to the server. When the other terminal acquires the backup data from the server, the identifier of the cutting rule 5 and the identifier of the combination mode 6 may be sent to other terminals. Inform other terminal data cutting rules and combination methods used for backup, so that other terminals can restore the original data.

It can be seen that, in the embodiment of the present invention, the original data to be backed up is obtained, and the original data to be backed up is cut into a plurality of data segments according to a preset cutting rule, and the plurality of data segments are combined to obtain a target different from the original data to be backed up. The data to be backed up is backed up to the server. The solution can cut and reorganize the original data to be backed up, obtain new data to be backed up, and then back up the data to be backed up to the server, which is equivalent to encrypting the original data to be backed up; even if the cloud backup account information leaks, Other users can't get the correct raw data, so you can improve the security of your data.

In addition, the embodiment of the present invention can also divide the backup data into a plurality of data segments, and sequentially back up to the server, thereby improving the efficiency of data backup.

After the server saves the data, the server may also synchronize the data to the terminal E. Specifically, the server sends the target to be backed up data P' to the terminal E, Rule ID F and mode ID G.

For example, the server receives the data synchronization request sent by the terminal E, and sends the target data to be backed up, the rule identifier, and the combination identifier to the terminal E according to the data synchronization request.

406. The terminal E determines, according to the combined identifier, a preset combination manner corresponding to the target to be backed up data, and restores the target to be backed up data into a plurality of data segments according to a preset combination manner.

The terminal E can determine, according to the rule identifier G, that the combination mode corresponding to the target data to be backed up P′ is the preset combination mode G, and then the terminal restores P′ to the data segment p1′ and the data segment p2′ according to the preset combination manner G... Data segment pm'.

407. The terminal E determines, according to the rule identifier, a preset cutting rule corresponding to the data to be backed up, and combines the restored data segments according to the preset cutting rule to obtain original backup data.

The terminal E determines, according to the mode identifier F, that the cutting rule corresponding to the data to be backed up is the cutting rule F. At this time, the data segment p1′, the data segment p2′, the data segment pm′ can be spliced into the original waiting according to the cutting rule F. Back up data P.

In this embodiment, the terminals D and E must obtain a plurality of preset cutting rules and a preset combination manner in advance. For example, when the cloud backup application client is installed on the terminals D and E in advance, the terminals D and E can be installed. A variety of preset cutting rules and preset combinations to encrypt or decrypt data.

Optionally, after the data P′ is backed up to the server, the terminal D may also obtain the backup data P′ from the server. For example, when the data is lost, the terminal D needs to obtain the previously backed up data from the server; therefore, the terminal D may also The server acquires the data P' to obtain the original data P. In this implementation, after the server backs up the data to be backed up, the server may further include:

The server sends the target data to be backed up to the terminal D;

The terminal D can restore the target data to be backed up into multiple data segments according to a preset combination manner;

The terminal D can combine the restored multiple data segments into the original data to be backed up according to the preset cutting rule.

It can be seen that, in the embodiment of the present invention, the terminal acquires the original data to be backed up, cuts the original data to be backed up into multiple data segments according to a preset cutting rule, and combines the plurality of data segments to obtain data different from the original data to be backed up. The target data to be backed up, and the target data to be backed up is backed up to the server. The solution can cut and reorganize the original data to be backed up, obtain new data to be backed up, and then back up the data to be backed up to the server, which is equivalent to encrypting the original data to be backed up; even if the cloud backup account information leaks, Other users can't get the correct raw data, so you can improve the security of your data.
