In order to make the objectives, technical solutions, and advantages of the present disclosure clearer, the following further describes the embodiments of the present disclosure in detail with reference to the accompanying drawings.

It should be noted that the restart of the present disclosure may be caused by some hardware failures, such as an abnormal power supply module, or a short circuit of a device, which causes excessive current during the startup process to cause the phone to restart; it may also be due to some software Error, restarting again during the startup process, resulting in an infinite restart cycle.

Because the system reads and writes the Data partition every time it is started, if an abnormal restart while writing to the Data partition will cause an error in the Data partition file system, generally speaking, the occasional abnormal operation can be repaired by the tool. Repairing will not cause too much loss to the data on the Data partition. However, if you restart repeatedly due to hardware or software failures, the Data partition will continue to accumulate errors, and eventually serious errors will occur, resulting in complete loss of user data.

The data protection method, device, electronic equipment, and computer-readable storage medium provided by the present disclosure are intended to solve the above technical problems in the prior art.

The technical solutions of the present disclosure and how the technical solutions of the present disclosure solve the above technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present disclosure will be described below with reference to the accompanying drawings.

An embodiment of the present disclosure provides a data protection method. As shown in FIG. 1, the method includes:

Step S101: before the system is started, the number of restarts is obtained from the preset address;

Optionally, the preset address may be a specific address of a raw partition. It should be noted that a raw partition is a special block device file that has not been formatted and cannot be read by Unix through the file system. The application is responsible for reading and writing to it. Not buffered by the file system. It is a device that is not directly managed by the operating system. Therefore, saving the number of restarts to a specific address of the raw partition can make the number of restarts accessible before and after the system is started.

Optionally, the number of restarts includes a first number of restarts and a second number of restarts;

If the first number of restarts is greater than the second number of restarts, the first number of restarts is determined as the number of restarts;

If the first number of restarts is not greater than the second number of restarts, the second number of restarts is determined as the number of restarts.

It is understandable that, in order to avoid an abnormality in the data update process that causes an error in the count, the dual backup mode of the first restart number and the second restart number can be used to alternately update. Specifically, when it is detected that a restart occurs during the startup process, such as some hardware failures, or some software errors, both the first restart times and the second restart times will increase by one. The dual backup alternate update mechanism can ensure that no misjudgment will be caused under abnormal conditions.

Step S102: If the number of restarts is not greater than the preset restart threshold, update the number of restarts, save the updated number of restarts to the preset address, and start the system;

It is understandable that generally the occasional restarts can be repaired by the repair tool and will not cause too much loss to the data on the Data partition. Therefore, the preset restart threshold can be set in advance, when the number of restarts is not greater than the preset When restarting the threshold, you can update the number of restarts, for example, increase the number of restarts by 1, and then save the updated number of restarts in a specific address of the bare partition again. Finally, start the application.

Optionally, the preset restart threshold is stored in a preset address.

It is understandable that the preset address can be stored in a specific address of the bare partition, and the application program is responsible for reading and writing operations on the bare partition without being buffered by the file system. Saving the preset restart threshold to a specific address of the raw partition can enable the preset restart threshold to be accessed before the system is started and when the system cannot be started.

Optionally, after the system is started for a preset time, the updated number of restarts stored in the preset address is cleared.

It is understandable that the startup of the system can be repeated. For example, the mobile phone shuts down after a period of startup. The startup at this time can be understood to be invalid. You can wait for the system to start for a preset time, such as 5 minutes or 10 minutes. It is considered that the startup of the system at this time is a valid startup, and then based on the specific address of the bare partition, the values of the updated first restart times and the updated second restart times saved in the specific address of the bare partition can be cleared to achieve similar feeding. The function of the dog. Then make sure that the number of restarts for the next cycle restarts.

Step S103: If the number of restarts is greater than the preset restart threshold, a fault prompt message is displayed.

It is understandable that if the number of restarts is greater than the preset restart threshold, the number of repeated restarts has reached a certain level. In order to prevent the accumulation of errors in the Data partition and cause the loss of user data, a fault message can be displayed. At this time, the user can repair the terminal so that the repaired Data partition can be restored, thereby protecting user data.

Optionally, if the number of restarts is greater than a preset restart threshold, a fault prompt interface including fault prompt information can also be generated;

Display the fault prompt interface.

Among them, the fault prompt information can be included in the fault prompt interface. Specifically, when the number of restarts is greater than the preset restart threshold, a fault prompt interface can be generated and displayed on the terminal to prompt the user of the cause of the current terminal failure. Users can perform maintenance more accurately based on the displayed fault causes, thereby protecting user data.

Optionally, the preset restart threshold can also be changed.

It is understandable that the preset restart threshold can be displayed in the background, and the current number of restarts can also be displayed. The preset restart threshold can be changed in different scenarios. For example, the preset restart threshold can be changed according to the terminal model or system version, so that The modified preset restart threshold is more suitable for the current terminal, which not only saves subsequent maintenance resources, but also protects user data to the greatest extent.

The embodiment of the present disclosure provides a data protection device. As shown in FIG. 2, the data protection device 20 may include: an acquisition module 201, an update module 202, and a display module 203, wherein:

The obtaining module 201 is used to obtain the number of restarts from a preset address before the system is started;

Optionally, the preset restart threshold is stored in a preset address.

Optionally, the data protection device may also include:

The reset module is used to reset the updated number of restarts stored in the preset address after the system is started for a preset time.

The display module 203 is configured to display failure prompt information if the number of restarts is greater than the preset restart threshold.

It is understandable that if the number of restarts is greater than the preset restart threshold, the number of repeated restarts has reached a certain level. In order to prevent the accumulation of errors in the Data partition and the loss of user data, a fault message can be displayed. At this time, the user can repair the terminal so that the repaired Data partition can be restored, thereby protecting user data.

Optionally, the display module 203 further includes:

The display sub-module is used to generate a fault prompt interface including fault prompt information if the number of restarts is greater than the preset restart threshold;
