For example, please refer to FIG. 1. FIG. 1 is a schematic diagram of a backup data deletion system provided by the present invention. The backup data deletion device is specifically integrated into a server, and is mainly used to determine whether a backup account offline time is greater than a preset duration. . If yes, the data deletion request is sent to the corresponding terminal, and the backup data stored in the server by the account is deleted according to the deletion confirmation instruction returned by the terminal.

In addition, as shown in FIG. 1, the backup data deletion system may further include a terminal. The deletion system can receive a data deletion request sent by the server, and can also generate a deletion confirmation instruction according to a user operation.

In the present embodiment, the description will be made from the perspective of the deletion device of the backup data, and the deletion device of the backup data may be specifically integrated in the server.

Referring to FIG. 2, FIG. 2 is a schematic flowchart of a method for deleting backup data according to Embodiment 1 of the present invention.

Step S101: Obtain an offline duration of the backup account.

The offline duration is specifically the duration between the last login time of the backup account of the user and the current time, and the method for obtaining the offline duration of the backup account by the server may also be multiple. For example, a timer is set to start timing when the user logs in to the server, until the next time the user logs in to the server, the timer resets the time and restarts the time. The time recorded on the timer is the backup account. Offline time. Optionally, the timer may also start counting when the user logs out of the login backup account, and then the timer resets and restarts the time when the user logs out of the backup account next time, and the time in the timer is offline. duration.

Preferably, each time the user logs in to the server using the backup account, the server can store its login time in the history. The login history information may further include a logout time of the backup account, a corresponding operation after logging in to the server, and the like. Therefore, the server can obtain the history record of the backup account, and then obtain the login time closest to the current time in the history record, determine the login time as the historical login time, and then calculate the backup account according to the current time and the historical login time. Offline time. That is, the step of obtaining the offline duration of the backup account includes:

It should be noted that the offline time length can be calculated in units of time, hour, minute, and the like. For example, the current time is 12:00 on September 12, 2016, and the last time the user logs in to the account is 12:00 on July 12, 2016. If the number of days is calculated, the offline duration is 62 days. The offline time is 1488 hours calculated in hours. In the present invention, it is more convenient to calculate in units of days, and the data calculated in hours or minutes is more accurate, and can be set according to user requirements.

In step S102, it is determined whether the offline duration is greater than the first preset duration. If yes, step S103 is performed. If no, the process returns to step S101 to continue to obtain the offline duration of the backup account.

The first preset duration may be used to determine whether the backup account is deprecated, and may be set by the user according to his own habits, or may be defaulted by the system, which is not specifically limited in this embodiment. Specifically, if the offline duration is greater than the first preset duration, the backup account may have been discarded by the user, and the backup data stored in the server may also be invalidated. If the offline duration is less than the first duration, it is temporarily impossible to determine whether the backup account is discarded. You can return to step S101 to continue to obtain the offline duration.

Step S103: Send a data deletion request to the terminal corresponding to the backup account, and receive a deletion confirmation instruction returned by the terminal according to the data deletion request.

Specifically, when determining that the offline duration is greater than the first preset duration, the server may automatically generate a data deletion request and send the data to the terminal corresponding to the backup account. The data deletion request may include backup account information, backup data corresponding to the account, offline duration information, and the like. Sending a request to the terminal may be performed by using an APP (Application) associated with the backup account, or may be based on identification information associated with the backup account, such as SIM (Subscriber) Identification Module, the customer identification module, sends a request, such as a text message to the user's mobile phone.

Further, after the terminal receives the data deletion request, the request confirmation command may be generated according to the operation of the user. For example, if the first preset duration is 60 days, the data deletion request received by the terminal is “User XXX has been offline for more than 60 days, and whether to delete the data backed up by the cloud server”. The terminal may be provided with an input interface, for confirming The requested APP is deleted, or the input control is executed, and the user can trigger the input interface by clicking, touching, sliding, etc. to confirm the data deletion request. For example, click the “Confirm Delete” button on the terminal screen, and the terminal generates a delete confirmation command and sends it to the server.

Step S104, deleting the backup data corresponding to the backup account according to the deletion confirmation instruction.

Specifically, in the embodiment of the present invention, the deletion confirmation instruction may be generated by the user according to the data deletion request acknowledged by the terminal. The deletion confirmation instruction includes a first instruction for agreeing to delete and a second instruction for rejecting deletion. If the user determines to delete, the deletion confirmation instruction for production is determined to be the first instruction, and is sent to the server, and the server receives the deletion confirmation command. The backup data stored in the server by the backup account is deleted. If the user refuses to delete, for example, after clicking the "Reject Delete" button in the terminal screen after receiving the data deletion request, the generated deletion confirmation command is the second instruction described above, and the server continues to save the backup data of the user.

It should be noted that, if the deletion confirmation command received by the server is the second instruction for rejecting deletion, that is, the backup account is still in use, the offline time in step S101 may be reset, and the server refuses to delete. The time of the deletion confirmation command is restarted from the start time. For example, when the server receives the delete confirmation instruction that refuses to delete, the timer for calculating the offline duration is reset to zero and the timing is restarted.

Preferably, in the embodiment, if the backup account is discarded, the server may not receive the deletion confirmation instruction returned by the user terminal after sending the data deletion request to the terminal, and the server cannot perform further operations according to the deletion confirmation instruction. A second preset duration may be set. If the deletion confirmation command returned by the terminal is not received within the second preset duration, the backup data corresponding to the backup account is deleted, and the second preset duration may further confirm whether the backup account is Deprecated.

In the actual application, if the server deletes the backup data corresponding to the backup account, and the user needs to continue using the account for some reasons, the deleted backup data needs to be restored to the cloud server for the user to continue to use. Therefore, in this embodiment, before deleting the backup data corresponding to the backup account in step S104, the deleted backup data is stored in the backup unit, and if the recovery instruction for retrieving the data is received after the server deletes the backup data, The server may restore the backup data in the backup unit to the server, that is, before the step of deleting the backup data corresponding to the backup account, the method may further include:

It can be seen that the method for deleting backup data provided by the embodiment of the present invention first obtains the offline duration of the backup account, and determines whether the offline duration is greater than the first preset duration. If yes, the data deletion request is sent to the terminal corresponding to the backup account, and the receiving confirmation command returned by the terminal according to the data deletion request is received, and the backup data corresponding to the backup account is deleted according to the deletion confirmation instruction. After the offline duration of the account meets the preset duration, the embodiment of the present invention can send a deletion request to the terminal corresponding to the account, and delete the backup data stored in the server according to the instruction returned by the terminal, so that the server will use a large amount of useless data. (For example, the backup data corresponding to the user's deprecated account) is cleaned to avoid waste of server resources, which can effectively place excessive consumption of cloud server space, improve cloud service response speed and user experience.

This embodiment will further explain the deletion method of the backup data of the present invention in further detail on the basis of the previous embodiment.

First, in the process of using the cloud backup, if the user discards the backup account for some reasons (such as forgetting the password, being stolen, etc.), the backup data stored in the backup account will continue to occupy the server resources. Increasing pressure will also affect the speed of interaction. Therefore, the present invention provides a method for deleting backup data, which can delete backup data corresponding to a backup account discarded by the user.

Referring to FIG. 3, FIG. 3 is a schematic flowchart of a method for deleting backup data according to Embodiment 2 of the present invention. In the embodiment of the present invention, a backup account is abandoned for use as an example, including:

Step S201: Obtain historical time information and current time information of the last login server of the backup account.

In this embodiment, each time the user logs in to the server using the backup account, the server can store its login time in the history. The login history information may further include a logout time of the backup account, a corresponding operation after logging in to the server, and the like. Therefore, the server can obtain the history record of the backup account, and then obtain the login time closest to the current time in the history, and determine that the login time is the historical login time.

Step S202: Determine an offline duration of the backup account according to the historical time information and the current time information.

It should be noted that the offline time length can be calculated in units of days, hours, minutes, etc., and can be set according to user requirements.

In step S203, it is determined whether the offline duration is greater than the first preset duration. If yes, step S204 is performed, otherwise, step S201 is returned.

The first preset duration may be used to determine whether the backup account is deprecated, and may be set by the user according to his own habits, or may be defaulted by the system, which is not specifically limited in this embodiment. Specifically, if the offline duration is greater than the first preset duration, the backup account may have been discarded by the user; if the offline duration is less than the first duration, the process may return to step S101 to continue to obtain the offline duration.

Step S204: Send a data deletion request to the terminal corresponding to the backup account.

Specifically, when determining that the offline duration is greater than the first preset duration, the server may automatically generate a data deletion request and send the data to the terminal corresponding to the backup account. The data deletion request may include backup account information, backup data corresponding to the account, offline duration information, and the like, and the request sent to the terminal may be pushed by the APP (Application, application) related to the backup account, or The request is sent according to the identification information (such as the SIM card identifier) associated with the backup account, for example, sent to the user's mobile phone in the form of a short message.

Step S205: The deletion confirmation command returned by the terminal is not received within the second preset duration, and the backup data corresponding to the backup account in the server is divided to obtain a plurality of sub-data.

In the embodiment of the present invention, if the deletion confirmation instruction returned by the terminal is not received within the second preset duration, the backup data corresponding to the backup account may be deleted. Preferably, when deleting backup data, the backup data may be first divided, for example, according to the data type, it may be divided into an address book, a memo, a short message, a chat record, a picture information, a multimedia information, and an application usage record, etc., of course, Divided according to data size or other means.

Step S206: Acquire priority information corresponding to each of the plurality of sub-data.

Specifically, different weight values may be set for the plurality of divided sub-data, and then the priorities corresponding to the plurality of sub-data are respectively obtained according to different weight values. For example, the priority of the plurality of sub-data divided according to the data type may be set as: Address Book > Memo > SMS > Chat Record > Picture Information > Multimedia Information > Application Usage Record.

Step S207, the backup data corresponding to the backup account is gradually deleted according to the priority information.

Preferably, before the step of deleting the backup data corresponding to the backup account, the backup data confirmed to be deleted may be stored in the backup unit. If a recovery instruction for retrieving data is received after the server deletes the backup data, the server restores the backup data in the backup unit to the server.

As shown in the above, the embodiment of the present invention first obtains the historical time information and current time information of the last login of the backup account, determines the offline duration of the backup account based on the historical time information and the current time information, and determines whether the offline duration is greater than the first preset duration. . If yes, the data deletion request is sent to the terminal corresponding to the backup account, and the deletion confirmation command returned by the terminal is not received within the second preset duration, and the backup data corresponding to the backup account in the server is divided to obtain multiple sub-data and obtained. The priority information corresponding to the plurality of sub-data respectively is used to gradually delete the backup data corresponding to the backup account according to the priority information. After the offline duration of the account meets the preset duration, the embodiment of the present invention can send a deletion request to the terminal corresponding to the account, and delete the backup data stored in the server according to the instruction returned by the terminal, so that the server will use a large amount of useless data. (For example, the backup data corresponding to the user's deprecated account) is cleaned to avoid waste of server resources, which can effectively place excessive consumption of cloud server space, improve cloud service response speed and user experience.
