Since a large amount of user information is stored in the terminal device, and the terminal device is prone to loss or damage, how to ensure the security of the data in the terminal device is an urgent problem to be solved.

The embodiment of the invention provides a data backup method and device, which can automatically back up data in the user terminal device to other terminal devices for storage, so as to avoid accidents such as loss or damage of the user terminal device, resulting in the terminal device data lost. The details are described below separately.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart diagram of a data backup method according to an embodiment of the present invention. The data backup method shown in FIG. 1 may include the following steps:

101. Monitor whether the first terminal enters a standby state.

In the embodiment of the present invention, the terminal device may be a smart phone, a smart watch, a palmtop computer, or a tablet battery. The present invention is not described in detail in the embodiments of the present invention, such as a brain, a personal digital assistant (PDA), a point of sales (POS), and the like.

In the embodiment of the present invention, when the first terminal enters the standby state, the user is not using the terminal device, so that the data backup operation can be performed to avoid the network bandwidth and processor resources occupied by the backup operation when the user uses the terminal device. Affect the user's experience.

102. If the first terminal has entered the standby state, determine whether a network connection has been established between the first terminal and the second terminal.

In the embodiment of the present invention, the first terminal may be a terminal device commonly used by the user, such as a smart phone. However, the general user of the smartphone needs to carry it with him, so the damage or loss of the external force may be large, which may result in the loss of user data in the smartphone. Therefore, it can be considered that the data in the smartphone is sent to the second terminal of the user for backup when the user does not operate the terminal device (ie, the standby state). Preferably, the second terminal can be a user's desktop computer, a notebook computer, and other unused smart phones, etc., which are generally placed at home and have sufficient free storage space, and thus are well suited for use as a backup device.

In the embodiment of the present invention, the desktop computer, the notebook computer, or the like can be used as a candidate terminal, and the terminal device selects one terminal from the candidate terminals as a second terminal to perform backup by using a certain rule.

As an optional implementation manner, the terminal device may acquire a remaining storage space size of each candidate terminal, and then select a candidate terminal with the largest remaining storage space as the second terminal. In this way, you can try to ensure the storage space required for the backup operation, and avoid the insufficient storage space to make the data backup fail.

As an optional implementation manner, the terminal device may acquire the current power of each candidate terminal, and then select the candidate terminal with the most current power as the second terminal. In this way, it is possible to avoid the backup interruption due to insufficient power of the second terminal during the backup process.

As an optional implementation manner, the account information of the first WIFI network accessed by the first terminal may be obtained, and then the account information of the first WIFI network is verified to be included in the preset secure WIFI network list; The account information of the network is included in the preset secure WIFI network list, and the first WIFI is determined to be a trusted network, so that the first terminal can perform a data backup operation when the link is in the first WIFI network.

In the case that the first WIFI network is determined to be a trusted network, the first terminal and the second terminal may be further restricted to access the first WIFI network, and the first terminal can back up the data to the second terminal. Since the coverage of the single WIFI network is small, when both the first terminal and the second terminal access the first WIFI network, it can be inferred that the distance between the first terminal and the second terminal is small (for example, The user accesses the home WIFI network at the same time, and operates the first terminal and the second terminal to perform data backup. The user is likely to operate the two terminals at the same time. Therefore, the current operating conditions are relatively safe, and the first terminal and the second terminal can be executed. Data backup operation between.

Optionally, the first terminal may obtain the distance between the first terminal and the second terminal directly by using the GPS information or the WIFI indoor positioning. If the distance between the first terminal and the second terminal is less than a preset threshold, step 102 is performed. The operation of determining whether a network connection has been established between the first terminal and the second terminal. For example, the preset threshold may be set to 2 meters. If the distance between the first terminal and the second terminal does not exceed two meters, it may be determined that the user operates two terminals at the same time, and the second terminal is reduced by the criminal Get the possibility of obtaining data backups, thus improving the security of data backup operations.

If, before the current operation, the first terminal has performed the work of synchronizing the data in the first terminal to the second terminal, in the current synchronization operation, the second terminal has already stored in some of the first terminals. data. As an optional implementation manner, the first terminal records the time of performing the last synchronization operation as a preset time point. In the current synchronization operation, the first terminal is modified and/or modified after the preset time point. The newly added data is then synchronized to the second terminal by the above-mentioned modified and/or newly added data after the preset time point.

It can be seen that, by implementing the method described in FIG. 1, the data in the user terminal device can be automatically backed up to other terminal devices for storage, so as to avoid data loss in the terminal device caused by accidents such as loss or damage of the user terminal device. .

If, before the current operation, the first terminal has performed the work of synchronizing the data in the first terminal to the second terminal, in the current synchronization operation, the second terminal has already stored in some of the first terminals. data. As an optional implementation manner, the first terminal records the time of performing the last synchronization operation as a preset time point, and in the current synchronization operation, acquiring the first terminal after the preset time point is modified and/or Or new data, and then synchronize the data modified and/or added after the preset time point to the second terminal.

204. Monitor whether the first terminal enters an awake state from the standby state.

In the embodiment of the present invention, in order to prevent the backup operation from occupying the network bandwidth and the processor resources when the user uses the terminal device, when the terminal device enters the awake state from the standby state, it is inferred that the user needs to use the terminal device, so the interruption may be considered. The data in one terminal is synchronized to the synchronization process in the second terminal.

205. If the first terminal enters the awake state from the standby state, interrupting the synchronization process of synchronizing data in the first terminal to the second terminal.

206. Record a breakpoint of the synchronization process for performing a breakpoint resume.
