And the terminal uploads the installation package and related information of the application program to the backup server for the second application program of which the installation package is not stored in the application server. By the optional implementation mode, only application programs which are not in the application server can be uploaded during backup, so that effective backup is guaranteed, and backup time is saved.
In practical application, the terminal may need to backup a plurality of application programs at one time, the query request may include identification information of the plurality of application programs, the application server may simultaneously return indication information indicating whether installation packages of the plurality of application programs are stored in the application server, and for a first application program in which an installation package is stored in the application server, the terminal only uploads relevant information of such application programs to the backup server, and does not upload installation packages of such application programs to the backup server. And for the second application program of which the installation package is not stored in the application server, the terminal uploads the installation package and related information of the application program to the backup server. Therefore, only application programs which are not in the application server can be uploaded during backup, and effective backup is guaranteed while backup time is saved.
In a specific application, the servers may be divided according to different functions, and in an optional implementation of the embodiment of the present invention, the backup server may be only responsible for storing the related information of the application program uploaded by the terminal, and when receiving the installation package of the application program uploaded by the terminal, the backup server sends the installation package of the application program to the storage server, and stores the storage address of the installation package of the application program in the storage server in association with the related information of the application program uploaded by the terminal.
In an optional implementation of the embodiment of the present invention, during backup and restoration, for a first application whose installation package is stored in an application server, after receiving a restoration request, a backup server sends relevant information of the backed up first application to a terminal, the terminal requests the application server for the installation package of the first application according to the relevant information of the first application, and the application server, in response to the request of the terminal, may transmit the installation package of the first application whose version is the same as that of the backup of the terminal to the terminal, or may transmit the installation package of the first application whose version is the latest to the terminal, which is not limited in this embodiment.

In a specific application, for the backup information uploaded by the same user, the backup server may store the identification information of the application program uploaded by the terminal, the related information, and the storage address of the installation package in an associated manner.
In an optional implementation manner of the embodiment of the present invention, the information related to the application program uploaded by the terminal in the step S106 includes, but is not limited to: version information and check data. At the time of the restoration, an appropriate version can be selected with reference to the backed-up version information. In addition, according to the verification data, integrity verification can be performed on the installation package of the application program uploaded by the terminal so as to ensure the data integrity of the uploaded installation package, and during backup and restoration, integrity verification can also be performed on the restored application program according to the verification data.
In an optional implementation of the embodiment of the present invention, the information about the application program uploaded by the terminal in the step S106 may further include: user data. That is, user data generated by the user using the application to be backed up, for example, a chat log generated by the user using the QQ, a chat log generated by the user using WeChat, information shared by a circle of friends, and the like. By adopting the optional implementation scheme, when the application program is restored, the corresponding user data can be restored to the user together, and the user experience is improved.
In the optional embodiment, optionally, during the restoring, if the version of the application program backed up by the user is not the latest version, the latest version may be restored to the user, so that air interface traffic consumption caused by updating the version after the user is restored is avoided, and user experience is improved. In this case, if the backup information further includes the user data, it may be further determined whether the format of the backed-up user data matches the format of the application program of the current latest version, and if not, the backed-up user data may be further converted into a corresponding format and then restored to the terminal, thereby avoiding a problem that the user cannot view the user data due to the fact that the version of the user data is inconsistent with the version of the application program when the user data is restored to the user.
In an optional implementation of the embodiment of the present invention, the terminal initiates the backup by a manual trigger of the user, or by an event trigger. Therefore, before step S102, the method may further include: receiving an input operation request of a backup application program, specifically, inputting the operation request through a keyboard, a key or a controllable touch screen by a user; alternatively, the occurrence of a predetermined trigger event is detected, the trigger event may be preset by a user, for example, the user may set to perform a backup before updating the system, and then step S102 to step S106 are performed first when the system needs to be updated. The specific trigger event may be set according to a specific situation, and the specific embodiment is not limited.
In an optional implementation of the embodiment of the present invention, in order to prevent the server from being maliciously attacked, before the terminal performs step S102, the terminal needs to provide account information to the server (the server may be referred to as an account server (ID server)), and after receiving the request of the user, the server generates an authentication code for the user and issues the authentication code to the terminal. After receiving the verification code, the terminal acquires the verification code, submits the verification code to the application server when sending an inquiry request to the application server in step S102, verifies the verification code by the application server (that is, the application server sends the verification code to the account server and receives a verification result returned by the account server), inquires whether an installation package of an application program to be backed up is stored in the application server after the verification is passed, and rejects the request of the terminal if the verification is not passed. Similarly, when the terminal uploads the backup data to the backup server, the terminal also needs to submit the verification code to the backup server, the backup server verifies the verification code (that is, the backup server sends the verification code to the account server and receives a verification result returned by the account server), the backup data uploaded by the terminal is received only after the verification is passed, and if the verification is not passed, the backup data uploaded by the terminal is rejected.
In an optional implementation of the embodiment of the present invention, the ID server may issue the verification code to the terminal through the short message, and the terminal may automatically obtain the verification code in the short message. Specifically, the terminal can automatically acquire the verification code in the short message through the following steps:
step 1, acquiring a platform signature of an operating system of a terminal. For example, the terminal may run an executable file previously injected into a system service (SystemServer) component of the operating system to obtain the platform signature, that is, the executable file is injected into the SystemServer component of the operating system, and by running the executable file, the platform signature of the operating system may be obtained. Or, in another optional implementation manner in an optional implementation of the embodiment of the present invention, the terminal may also obtain the high permission through some programs of the partition by flushing a recovery (recovery) partition, and specifically, may set a module in the ramdisk, where the module is used to scan the partition of the operating system and view the platform signature of the operating system after the scanning.
And 2, acquiring the authority for reading the content of the short message based on the acquired platform signature. After the platform signature is obtained, the obtained platform signature of the operating system may be used to re-sign the application, so that the application obtains the corresponding right of the operating system, where in this embodiment, the corresponding right refers to a right to read the content of the short message).
And 3, acquiring the verification code in the short message received by the terminal based on the acquired permission for reading the content of the short message. In a specific application, the terminal may call an Application Program Interface (API) for acquiring the content of the short message based on the acquired permission, read the content of the short message received by the terminal from a database of the terminal, and then acquire the verification code from the content of the short message. In this embodiment, the API for obtaining the content of the short message belongs to a high-level API, and an application with system permission can call such API, so in this embodiment, the corresponding permission is obtained through the platform signature to call the API to obtain the content of the short message. After the terminal acquires the verification code, the acquired verification code can be input into a dialog box in which the verification code needs to be filled, so that the automatic filling of the short message verification code is realized, and the user experience is improved.
In the embodiment of the present invention, the application server, the backup server, the storage server, and the ID server are provided separately according to the function of each server, but the present invention is not limited to this, and may be combined into the same server in a specific application.
