The data backup method of this preferred embodiment includes:

Step S101, when it is detected that the terminal has increased data, acquire the content information of the incremental data.

For example, when the terminal detects that there is data increase, it acquires the storage content of the increased data; wherein, the incremental data is data added to the added data relative to the data before the increase. The terminal may be a device such as a mobile phone or a tablet computer.

Step S102, detecting whether the content information has preset identification information, and obtaining a detection result.

For example, the terminal detects whether there is a preset keyword in the content information. The preset identification information is, for example, a preset keyword. The preset keyword is used to identify important data, that is, the important data is data that is more important to the user. , to monitor important data. For example, the preset keyword may be the name of important data, such as the name of the application program specified by the user, or the name of the specified folder or file in the specified application program. If the terminal detects that the preset keyword exists in the increased data content, it indicates that the content of important data has increased; if the terminal detects that the preset keyword does not exist in the increased data content, it indicates that the content of important data No increase.

Step S103, backup the incremental data according to the detection result.

For example, when the terminal detects that the preset keyword exists in the increased data content, it backs up the increased data corresponding to the preset keyword, so as to back up important data in time; when the terminal detects that the increased data When the preset keyword does not exist in the content, the terminal may back up the added data according to the capacity of the added data, or may back up the added data at certain intervals.

For example, in the above step S103, the step of backing up the incremental data according to the detection result may include:

(1) displaying prompt information, the prompt information is used to prompt the user to input the storage location;

(2) receiving the storage location input by the user according to the prompt information;

(3) Backing up the incremental data to the storage location.

For example, the terminal displays a prompt box to prompt the user to input a storage path, and then the user inputs a specific storage path in the prompt box, and then the terminal stores the incremental data in a location corresponding to the storage path.

The data backup method in this preferred embodiment, because by detecting whether there is preset identification information in the newly added data, to judge whether the terminal has important data increase, so as to back up the important data in time, the flexibility of backup is improved, Important data loss is avoided.

Please refer to FIG. 2 . FIG. 2 is a flowchart of a data backup method provided in Embodiment 2 of the present invention.

The data backup method of this preferred embodiment includes:

Step 201, when it is detected that the terminal has increased data, acquire the content information of the incremental data.

For example, when the terminal detects that there is data increase, it acquires the storage content of the increased data; wherein, the incremental data is data added to the added data relative to the data before the increase. The terminal may be a device such as a mobile phone or a tablet computer.

Step S202, detecting whether the content information has preset identification information, and obtaining a detection result.

For example, the terminal detects whether there is a preset keyword in the content information. The preset identification information is, for example, a preset keyword. The preset keyword is used to identify important data, that is, the important data is data that is more important to the user. , to monitor important data. For example, the preset keyword may be the name of important data, such as the name of the application program specified by the user, or the name of the specified folder or file in the specified application program.

For example, the terminal receives and stores the identification information input by the user in advance to obtain the preset identification information. For example, the user pre-sets and stores keywords in the terminal to obtain the preset identification information. If the terminal detects that the preset keyword exists in the increased data content, it indicates that the content of important data has increased; if the terminal detects that the preset keyword does not exist in the increased data content, it indicates that the content of important data No increase.

Step S203, if the content information has the preset identification information, backup the incremental data corresponding to the preset identification information;

For example, when the terminal detects that the preset keyword exists in the added data content, the added data corresponding to the preset keyword is backed up; that is, important data is backed up.

For example, in the above step S203, the step of backing up the incremental data corresponding to the preset identification information may include:

(1) displaying prompt information, the prompt information is used to prompt the user to input the storage location;

(2) receiving the storage location input by the user according to the prompt information;

(3) Backup the incremental data corresponding to the preset identification information to the storage location.

For example, the terminal displays a prompt box to prompt the user to input a storage path, and then the user inputs a specific storage path in the prompt box, and then the terminal stores the incremental data corresponding to the preset identification information in a location corresponding to the storage path.

Step S204, if the preset identification information does not exist in the content information, the capacity of the incremental data is obtained, and the incremental data is backed up according to the capacity of the incremental data.

For example, when the terminal detects that the preset keyword does not exist in the added data content, the added data may be backed up according to the capacity of the added data. For example, the terminal may also back up the incremental data to the storage location specified by the user according to the storage location specified by the user.

In order to reduce system consumption, when the capacity of the increased data is greater than a certain value, the terminal performs backup, that is, the step of backing up the incremental data according to the capacity of the incremental data includes:

(1) judging whether the capacity of the incremental data exceeds a preset threshold;

(2) If it is determined that the capacity of the incremental data exceeds the preset threshold, the incremental data is backed up.

For example, the preset threshold can be set according to user needs. When the terminal detects that the increased data capacity is greater than the preset threshold, the increased data will be backed up; if the terminal detects that the increased data capacity is less than or equal to the preset When the threshold is set, the increased data will not be backed up.

Step S205, generating and storing backup record information.

For example, while backing up the increased data, the terminal records the backup time, backup object, backup reason, etc. to obtain the backup record information; and then stores the backup record information in the preset database.

The data backup method in this preferred embodiment, because by detecting whether there is preset identification information in the newly added data, to judge whether the terminal has important data increase, so as to back up the important data in time, the flexibility of backup is improved, Avoid the loss of important data. When there is no preset identification information in the newly added data, that is, when only unimportant data is added, the unimportant data is backed up according to the capacity of the added data, thereby reducing power consumption.

Please refer to FIG. 3 . FIG. 3 is a flowchart of a data backup method provided in Embodiment 3 of the present invention.

In this embodiment, the terminal is a smart phone as an example for detailed description. The data backup method in this preferred embodiment includes:

Step S301, when the smart phone detects that there is data increase, acquire the content information of the incremental data.

For example, when the smart phone detects that there is an increase in data, it acquires the storage content of the increased data; wherein, the incremental data is the increased data after the increase relative to the data before the increase. For example, when there is an increase in the data of the text message in the smart phone, the increased data of the text message is obtained.

In step S302, the smart phone detects whether the content information has preset identification information, and obtains the detection result.

For example, the preset identification information is the name of the memo or the name of a certain file or folder in the memo; for example, if the preset keyword is the name of the memo, when the smart phone detects that the The mobile phone obtains the name of the root directory file corresponding to the added data, and the smart phone detects whether the name of the memo exists in the name of the root directory file corresponding to the added data, and if the smart phone detects that the name of the memo exists in the name of the root directory file, execute Step S303; if the smart phone detects that the name of the memo does not exist in the file name of the root directory, then execute step S304;

Step S303, if the content information has the preset identification information, backup the incremental data corresponding to the preset identification information;

For example, when there is an increase in text messages or memo data in the smart phone, the smart phone determines that the preset keyword exists in the added data content, and at this time the smart phone backs up the added data of the memo. For the data added by the text message, the smart phone can store it according to the existing storage method; or judge whether the capacity of the data added by the text message is greater than a preset threshold, and if it is greater, the data added by the text message is backed up.

Step S304, if the preset identification information does not exist in the content information, acquire the capacity of the incremental data.

For example, when there is an increase in text messages or WeChat data in the smart phone, the smart phone detects that the name of the memo does not exist in the increased data content, and the smart phone then obtains the increased data size of the text message or the increased data size of the WeChat.

Step S305, the smart phone judges whether the capacity of the incremental data exceeds a preset threshold;

For example, if the preset threshold is 200M, the smart phone judges whether the increased data size of the SMS or the increased data size of WeChat exceeds 200M; if the smart phone determines that the increased data size of the SMS or the increased data size of the WeChat does not exceed 200M, then perform the steps S306. If the smart phone judges that the data size added by the text message or the data size added by WeChat exceeds 200M, step S307 is executed.

Step S306, if it is determined that the capacity of the incremental data does not exceed the preset threshold, then the increased data is not backed up.

For example, when the smart phone judges that the data size added by the text message or the data size added by WeChat does not exceed 200M, the smart phone does not back up the data added by the text message or WeChat.

Step S307, if it is determined that the capacity of the incremental data exceeds the preset threshold, backup the incremental data.

For example, when the smartphone judges that the data size added by the SMS exceeds 200M, the smartphone backs up the data added by the SMS; or when the smartphone judges that the data size added by WeChat exceeds 200M, the smartphone backs up the data added by WeChat.

The data backup method in this preferred embodiment, because by detecting whether the preset identification information exists in the newly added data of the smart phone, to judge whether the terminal has important data increase, so as to back up the important data in time, the flexibility of the backup is improved To avoid the loss of important data; when there is no preset identification information in the newly added data in the smart phone, that is, when only unimportant data increases, the unimportant data is backed up according to the capacity of the increased data , reduces power consumption.
