Description

Application backup method, electronic device, storage medium and program product

Technical Field

The present application relates to the field of internet technologies, and in particular, to a method for backing up applications, an electronic device, a storage medium, and a program product.

Background

With the continuous development of technology, various application software is also continuously and iteratively updated. After upgrading a new version, some application software may have unstable versions, such as flashing back, blocking, and crashing, which may affect the user experience.

In the prior art, a third party application manufacturer is usually waited for repairing and upgrading the application version, so that the problem that the version is unstable after the application software is upgraded is solved, but during the process of repairing and upgrading the application version, a user still suffers from the problem of unstable application version, and the use experience of the user is reduced.

Disclosure of Invention

The application backup method, the electronic device, the storage medium and the program product solve the problem that the use experience of a user is affected due to the fact that the version of the application is unstable after the version of the application is updated in the prior art.

In order to achieve the above purpose, the application adopts the following technical scheme:

in a first aspect, the present application provides an application backup method, including: the electronic equipment detects whether an application to be upgraded exists in real time; when the application to be upgraded exists and the application to be upgraded is an application with the use frequency exceeding a preset frequency standard in a preset time period, prompting a user to perform backup operation on application version data of the application to be upgraded; when the user selects to carry out backup operation on the application version data of the application to be upgraded, the electronic equipment responds to the backup operation on the application version data of the application to be upgraded and backs up the version data of the application to be upgraded before upgrading.

Therefore, whether the application is upgraded or not can be automatically detected, and when the application with the use frequency exceeding the preset frequency standard in the preset time period is detected, namely the application is upgraded by the common application, a user is prompted to backup the application version data, and when the situation that the version is unstable after the common application is upgraded, the user can timely fall back to the previous stable version without affecting the user experience. The application for version data backup can be screened in a targeted manner, and the storage space is not wasted.

In some possible implementations, after the application upgrade, the method further includes:

the electronic equipment responds to an instruction for recovering the application version data, and uninstalls the current version of the application; and recovering the application by using the backup version data of the application. Since the version data before the application is backed up, when the version instability occurs after the application is upgraded, the user can restore the application to the previously stable version by using the backed-up data.

In some possible implementation manners, the method for determining the application to be upgraded as the application with the use frequency exceeding the preset frequency standard in the preset time period may specifically be the following manner:

Acquiring the flow and the electric quantity used by each application in a preset time period; then calculating the comprehensive use value of the flow and the electric quantity of each application in a preset time period; sequencing the applications according to the sequence of the comprehensive use values from big to small; if the application to be upgraded is any one of the preset number of applications which are ranked at the front, the application to be upgraded is determined to be the application with the use frequency exceeding the preset frequency standard in the preset time period. Therefore, according to the comprehensive use condition of the flow and the electric quantity of each application in the preset time period, the application with the use frequency exceeding the preset frequency standard, namely the common application, can be determined, so that the backup operation is further carried out on the version data of the common application.

In some possible implementations, the electronic device may further backup the current version data of the first application in response to an instruction from the user to add the current version data of the first application to the application backup space. The first application is only intended to distinguish from the application to be upgraded and represents an application that is not to be version-upgraded. Thus, the electronic equipment supports the user to backup the version data before the application to be upgraded is upgraded, and also can backup the current version data of the application after the application is upgraded.

In some possible implementations, if the application backup space is full, the backup of version data before upgrading the application to be upgraded may be implemented in the following manner:

the electronic device responds to an instruction for replacing the application version data stored in the application backup space; and replacing the application version data selected by the user with the version data before the application to be upgraded is upgraded. Therefore, the version data before upgrading the application to be upgraded can be backed up by adopting a mode of replacing other backup version data under the condition that the application backup space is full.

In some possible implementations, if the application backup space is full, the backup of version data before upgrading the application to be upgraded can be further implemented in the following manner:

the electronic equipment responds to an instruction for increasing the application backup space, and the application backup space is increased; and backing up version data before upgrading the application to be upgraded in the increased application backup space. When the application backup space is full, the user can manually increase the backup storage space, and the newly increased application backup space is utilized to backup version data before the application to be upgraded is upgraded.

In some possible implementations, the electronic device deletes the second application version data stored to the backup storage space in response to an instruction to delete the second application version data. The second application is a user selected application. Thus, the user can reduce the occupation of unnecessary application backup space without deleting the data which is already backed up by a certain application.

In some possible implementations, the electronic device jumps to an operation interface of the application version data backup in response to an instruction of the application version data backup triggered by the user; the operation interface comprises operations of adding, deleting and recovering the application version data. The user can trigger an instruction of backing up the application version data, and perform operations such as adding, deleting, recovering and the like on the application version data at an operation interface of backing up the application version data so as to realize management of the application version data.

In some possible implementations, determining the preset time period may be implemented in the following manner:

reading the moment when the electronic equipment detects that the application to be upgraded exists last time, and recording the moment as the first time; reading the moment when the electronic equipment detects that the application to be upgraded exists, and recording the moment as second time; the time period from the first time to the second time is determined as a preset time period.

In a second aspect, the present application provides an electronic device comprising a processor and a memory, wherein one or more computer programs are stored in the memory, the one or more computer programs comprising instructions; the instructions, when executed by the processor, cause the electronic device to perform the application backup method as described in any one of the possible designs of the first aspect above.

In a third aspect, the present application provides a computer storage medium comprising computer instructions which, when run on an electronic device, perform an application backup method as described in any one of the possible designs of the first aspect above.

In a fourth aspect, the present application provides a computer program product for performing the application backup method described in any one of the possible designs of the first aspect above when the computer program product is run on a computer.

Detailed Description

The terms first, second and the like in the description and in the claims and drawings are used for distinguishing between different objects and not for limiting a particular order.

For clarity and conciseness in the description of the following embodiments, a brief description of the related art will be given first:

the "backup" tool may protect data from unexpected loss if the hardware or storage media of the system fails. For example, a copy of the data in the hard disk may be created using a "backup" and then stored to other storage devices. The backup storage medium may be either a logical drive (e.g., hard disk), a stand-alone storage device (e.g., removable disk), or an entire disk library or tape library organized and controlled by an automatic changer. If the original data on the hard disk is accidentally deleted or overwritten, or the data is not accessible due to a hard disk failure, the data may be restored from the archive copy.

With the continuous development of technology, various application software is also continuously and iteratively updated. Some applications may flash back, crash, or crash after upgrading the new version, and need to be rolled back to the last stable version. In the prior art, when each application is upgraded, the last version of each application is usually backed up, so that when the version is unstable after the application is upgraded, the last stable version can be backed up. Because each application is backed up in the prior art, but in actual use, the problem that each application is unstable after upgrading the version does not occur, so that the problem that the memory space of the electronic equipment is excessively occupied exists.

In view of this, the present application provides a method for application backup, which can set an option of application backup in the "set" application software of the electronic device in advance, the option supports user-defined backup of the application software, and can also automatically detect application software with higher use frequency, and when upgrading the application software with higher use frequency, prompt the user to backup a version of the application software, so that the user can selectively backup the application software, and after the problem of instability of the application software after upgrading, the user can return to the previous version, and save the storage space.

Referring to fig. 3, fig. 3 is an interface schematic diagram of a display screen of an electronic device used by a user according to an embodiment of the present application.

The user may click on the "set" icon 301 in fig. 3, open the set interface, where the schematic diagram of the set interface is shown in the interface a in fig. 4, and fig. 4 is a schematic diagram of an application version backup function interface provided in the embodiment of the present application.

The user may click on the "application version backup" option shown in interface a of fig. 4 and then jump to a configured interface, interface B. The user can press one button of the interface B for a long time, and can pop up three function buttons, namely 'restore', 'add', 'delete'; the user clicks a 'restore' option to restore the application to a saved version, and the operation interface is shown as an interface A and an interface B in FIG. 5; fig. 5 is a schematic diagram of an operation interface for recovering an application version according to an embodiment of the present application.

The user clicks the 'add' option, and the version data of one application stored currently can be replaced by the version data of other applications; for example, the user selects to replace version data stored in the application a with one version data of the application D, the operation interfaces are shown as an interface B and an interface C in fig. 6, and fig. 6 is a schematic diagram of an operation interface for adding an application version according to an embodiment of the present application. The user selects application D and clicks the ok button to complete the addition operation.

The user clicks the 'delete' option to delete the application version data stored in the current application; the operation interfaces are shown in an interface a and an interface B in fig. 7, and fig. 7 is a schematic diagram of an operation interface for deleting an application version according to an embodiment of the present application. After the user clicks the delete button and confirms, the application is deleted and a default icon style is displayed, such as an icon of "please add application".

In the embodiment of the application, in the option of setting the application version backup in the application, the number of the applications capable of carrying out the application version backup can be set to be the default number of the system, and the user definition is supported. For example, the default number of applications capable of performing application version backup is 3, and the user can perform number setting according to the actual memory size of the electronic device. The number of the application version backups is limited, so that the version backups can be carried out for part of the applications, all the applications are prevented from being subjected to the version backups, and the occupation of unnecessary memory space is reduced.

Referring to fig. 8, fig. 8 is a flowchart of an application version backup according to an embodiment of the present application.

Firstly, setting an application version backup function in a setting application, and setting the application version backup function on a setting interface when the electronic equipment leaves a factory. For example, the number of supported version-backed applications may be set to 3.

Then, the user performs specific setting of the "application version backup" function, for example, the user may perform custom setting on the number of applications that can perform version backup according to the actual memory size of the electronic device, for example, the number is set to 5. The user may also select a specific application in the "application version backup" option interface, e.g., the user sets application a as an application for which version backup is possible.

The system side detects whether the application to be upgraded performs version upgrading operation in real time, and if the application to be upgraded is detected to perform version upgrading operation, the system side sends out notification of the detected application upgrading to perform subsequent popup operation so as to prompt a user whether to perform backup operation of application version data.

When the system side detects that the application to be upgraded is upgraded, the system side can detect whether the application backup space is occupied, if the application backup space is occupied, the popup operation is not performed, whether the user performs the operation of backing up the version data of the application which is not upgraded is not prompted, and the step of ending the backup is directly entered. If the system side detects that the application backup space is not fully occupied, the system side screens the applications according to the electricity quantity and the flow quantity used by each application in a preset time period, and screens a plurality of applications with more electricity quantity and more flow quantity used in the preset time period, namely, the applications with more frequency of use in the preset time period than a preset frequency standard. Judging whether the application to be upgraded is an application with the use frequency exceeding a preset frequency standard in a preset time period, if so, performing popup operation on the system side to prompt a user whether to perform version data backup of the application before upgrading; if not, the popup window operation is not performed, and the step of ending the backup is directly entered. After the popup window prompts the user, if the user selects to perform the backup operation of the application version data, the system side can save the version data before the application is upgraded to a preset directory. When a user opens an application version backup interface in a set application, a specific version number of the backup is displayed in the interface. So far, the application version backup is completed.

Judging whether the application is an application with the use frequency exceeding a preset frequency standard in a preset time period or not by calculating the use electric quantity and the flow of each application in the preset time period, namely a common application, and backing up the application if the application to be upgraded is the common application; if the application is not a common application, version backup of the application is not needed, so that unnecessary occupation of memory space can be avoided.

In addition, if the application to be upgraded is judged to be not a common application by the system, the popup window is not operated when the application is upgraded, if a user wants to backup the version of the application, the operation of adding the application can be performed on an application version backup option interface in the application, and the processor responds to an instruction of adding the current version data of the application to a backup storage space and backs up the current version data of the application.

In some possible implementations, the method for determining the preset time period may be implemented in the following manner:

reading the moment when the application to be upgraded is detected to exist last time, and recording the moment as the first time; reading the moment when the application to be upgraded is detected to exist at the time, and recording the moment as second time; the time period from the first time to the second time is determined as a preset time period.

In some possible implementations, the user may also perform a version backup operation on the application when there is no application to be upgraded. In order to distinguish from the application to be upgraded, the application is represented as a first application. Specifically, the user may manually add the first application to the interface of "application version backup" in the "setting", and the system side may backup the current version data of the first application.

Referring to fig. 9, fig. 9 is a flowchart of another application version backup according to an embodiment of the present application.

The main difference between fig. 9 and fig. 8 is that when the system side detects that there is an application to upgrade, the operation flow of whether to perform version backup for the upgraded application is different.

The first two steps are the same as the implementation process of the previous embodiment, and are not described here again. The system side detects whether an application to be upgraded exists in real time, if the application to be upgraded is detected, version upgrading operation is performed, notification of the detected application upgrading is sent out, subsequent popup operation is performed, and whether a user performs backup operation of application version data before upgrading is prompted.

And then the system side screens the applications according to the electricity quantity condition and the used flow condition of each application in a preset time period, and screens a plurality of applications with more electricity quantity and more used flow in the preset time period, namely, the applications with more use frequencies than a preset frequency standard in the preset time period. If the application to be upgraded is an application with the use frequency exceeding the preset frequency standard in the preset time period, the system side performs popup operation to prompt a user whether to perform version data backup of the application before upgrading. The user can choose whether to backup the application to be upgraded according to the actual demand.

If the user selects to backup the version data of the application to be upgraded, the system side can detect whether the application backup space is occupied, and if the application backup space is occupied, the system side can prompt the user in a popup window mode whether the data already stored in the application backup space needs to be replaced with the version data before the application to be upgraded is upgraded; or prompting the user whether to increase the application backup space, and after the user increases the application backup space, storing the version data before upgrading the application to be upgraded into the increased application backup space.

If the system side detects that the application backup space is not occupied, the system side can store the version data before the application is upgraded to a preset directory. When a user opens an application version backup interface in a set application, a specific version number of the backup is displayed in the interface. So far, the application version backup is completed.

Referring to fig. 10, fig. 10 is a flowchart of screening a common application according to an embodiment of the present application.

The system detects whether the application to be upgraded exists in real time, and when the application to be upgraded exists, the application version backup notification is triggered.

And then the system side reads the time of the last application upgrading notification and the time of the current application upgrading notification, and acquires a preset time. The system side calculates the comprehensive use value of the flow and the electric quantity of each application in a preset time period; sequencing the applications according to the sequence from the large value to the small value; if the application for version upgrading is any one of the preset number of applications which are ranked at the front, determining the application for version upgrading as the application with the use frequency exceeding the preset frequency standard in the preset time period, namely the common application. The preset number can be flexibly set according to actual conditions. The specific implementation process is as follows:

And sequencing the applications according to the numerical value of the flow used by the applications in a preset time period by the system side. Specifically, the system side performs normalization processing on the flow value used by each application in units of MB, for example, 1.2G is used by one application, the value obtained after the normalization processing is 1200, and the value of the flow used by each application in the preset time period is calculated according to the rule. And then according to the obtained flow values used by the applications, arranging the applications according to the sequence from the large value to the small value, and then selecting the application N before the flow use value. The number of specific screening is set according to the number of version backup carried out by the supporting application in the 'setting' application. For example, in the "set" application, N applications are supported to perform version backup, in this embodiment, N is taken as 5, and then an application with a flow value of 5 is screened, for example, the application with the front 5 is sequentially application a, application B, application C, application D, and application E, and the flow values corresponding to the application a1, B1, C1, D1, and E1 respectively.

And the system side sorts the applications according to the values of the electric quantity used by the applications in a preset time period. Specifically, the system side performs normalization processing on the electric quantity value used by each application in units of minutes, for example, one application uses 2 hours, the value obtained after the normalization processing is 120, and the value of the electric quantity used by each application in a preset time period is calculated according to the rule. And then according to the obtained electric quantity values used by the applications, arranging the electric quantity values in a sequence from large to small, and then selecting the application N before the electric quantity use value. Likewise, the number of specific screens is set according to the number of version backups performed by the supporting application in the "set" application. For example, 5 applications are supported in the 'set' application to carry out version backup, and the application with the power value of 5 before is screened out. For example, the application of the first 5 of the selected electric quantity values is application a, application D, application F, application C and application G in order, and the electric quantity values corresponding to the application a2, b2, C2, D2 and e2 are respectively.

The system side performs weighting processing on the flow values of the first 5 applications, namely, the flow values used by the application A, the application B, the application C, the application D and the application E are multiplied by the weighting value of 0.5 to obtain new values which are respectively 0.5a1,0.5b1,0.5c1,0.5d1 and 0.5e1. Similarly, the system side performs weighting processing on the electric quantity values of the first 5 applications, namely, the electric quantity values used by application A, application D, application F, application C and application G are multiplied by the weighting value of 0.5 to obtain new values of 0.5a2,0.5b2,0.5c2,0.5d2 and 0.5e2 respectively.

And then adding the weighted value of the flow value used by each application and the weighted value of the electric quantity value to obtain the comprehensive use value of the flow and the electric quantity of each application in a preset time period. The first 5 applications are selected as common applications according to the added values. The specific calculation process is as follows:

when the application B in the first 5 applications of the flow value is not the application of the first 5 applications of the electric quantity use value, assigning the electric quantity value of the application B as 0 for addition operation; and (5) in the 5 applications with the same electric quantity use value, the application F and the application G are not the application with the flow use value of 5, and the flow use values of the two applications are assigned to be 0 for addition operation. The flow value and the electric quantity value used by the application are multiplied by the weighted value, so that the common application is screened by comprehensively considering the condition of the flow used by the application and the condition of the electric quantity used by the application.

Referring to fig. 11, fig. 11 is a flowchart of an embodiment of the present application for recovering an application version.

The user opens the 'setting' application, finds the application which wants to restore the version in the 'application version backup' function interface in the 'setting' application, for example, selects the application A to restore the version, long presses the option box of the application A, pops up the 'restore' option, clicks the 'restore' button, then the system side can analyze the data of the version data stored under the preset directory, deletes the current application version, and restores the stored version.

After the system side successfully restores the saved version, the system side informs the user that the version data is successfully restored, and reminding operation can be performed in the forms of a bullet frame and the like. So far, the recovery version flow ends.

Referring to fig. 12A, fig. 12A is a schematic diagram of a module connection structure related to an implementation process of backup of an application version according to an embodiment of the present application.

The implementation process of the backup of the application version in the embodiment of the application relates to a module which mainly comprises an upgrade management module, a battery management module, a flow management module, a setting module, a notification management module, a backup detection module, a backup recovery module and a backup data management module, wherein a specific software framework is shown in fig. 12A.

Referring to fig. 12B, fig. 12B is a timing chart of an application version backup according to an embodiment of the present application.

The implementation process of the application version backup in the embodiment of the application mainly relates to interaction of a plurality of main modules. The upgrade management module and the notification management module are two modules in the application program, and the backup detection module and the backup data management module may be two modules in the 'set' application. The timing diagram specifically comprises the following steps:

and S1201, the upgrade management module sends the message of the application version upgrade to the notification management module.

When the application is upgraded, the application upgrading management module triggers an application version upgrading instruction and transmits an application version upgrading message to the notification management module.

S1202, the notification management module sends a notification of whether the updated application is a common application to the backup detection module.

The notification management module receives the application version upgrading message and sends a notification for detecting whether the upgraded application is a common application to the backup detection module.

And S1203, detecting whether the updated application is a common application or not by the backup detection module.

And after receiving the notice of detecting whether the updated application is the common application, the backup detection module detects whether the updated application is the common application.

And S1204, the backup detection module performs application version backup confirmation and sends a confirmation message to the backup data management module.

When the backup detection module detects that the updated application is a common application, application version backup confirmation is carried out, and a confirmed message is sent to the backup data management module so that the backup data management module can backup the application version data.

And S1205, not backing up the application version.

And when the backup detection module detects that the updated application is not the common application, the version backup operation is not carried out on the updated application.

S1206, the backup data management module receives the application version backup confirmation message and sends a request for acquiring the application version backup data to the upgrade management module.

And after receiving the application version backup confirmation message, the backup data management module sends a request for acquiring the application version backup data to the upgrade management module so as to acquire the backup data.

S1207, the upgrade management module sends the data of the application version backup.

And after receiving the data request for acquiring the application version backup sent by the backup data management module, the upgrade management module sends the data needing to be backed up to the backup data management module.

S1208, the backup data management module stores the backup application version data under the appointed catalogue.

And after receiving the application version backup data sent by the upgrade management module, the backup data management module stores the application version backup data under a designated directory to complete the backup of the application version data.

According to the embodiment of the application, whether the updated application is a common application is detected when the application is updated, when the application is the common application, the application is automatically confirmed to need version backup, and the version backup data of the application is stored under a designated directory. Automatic backup of common applications is achieved. When the updated application is not the common application, the version backup of the application is not performed, and the memory space is saved.

Referring to fig. 13A, fig. 13A is a timing chart of another backup of an application version according to an embodiment of the present application.

The difference between this embodiment and the embodiment of fig. 12B is mainly that, in the embodiment of the present application, when a notification for detecting whether the updated application is a common application is sent to the backup detection module, it needs to determine whether the backup space of the application is full, and if so, the updated application is not backed up; if not, the operations of steps S1203-S1208 in FIG. 12B are performed. The implementation of the application specifically comprises the following steps:

S12021, the backup detection module detects whether the application backup space is occupied.

And after receiving the application version upgrading message, the backup detection module detects whether the application backup space is occupied.

S1203, detecting whether the updated application is a common application.

When the backup detection module detects that the application backup space is not occupied, the backup detection module detects whether the updated application is a common application after receiving a notification for detecting whether the updated application is the common application. And proceeds to steps S1204-S1208.

When the backup detection module detects that the application backup space is full, step S1205 is executed, that is, the application version is not backed up.

Before version backup is performed on the upgraded application, the embodiment of the application firstly judges whether the version backup space of the application is occupied, and if so, the version backup operation is not performed on the upgraded application, so that the occupation of excessive memory is further avoided.

Referring to fig. 13B, fig. 13B is a timing chart of another backup of an application version according to an embodiment of the present application.

The main difference between fig. 13B and fig. 13A is that when it is detected that there is an upgraded application, the implementation procedure of whether to make version backups for the upgraded application is different.

After receiving the notification that the updated application is the common application, the backup detection module detects that the updated application is the common application, and continues to execute step S1204. If it is detected that the upgraded application is not a usual application, step S1205 is executed.

S1204, a backup detection module detects whether the application backup space is occupied.

The backup detection module detects whether the application backup space is occupied, and if not, step S12041 is executed; if the application backup space is full, step S12042 is performed.

S12041, the backup detection module performs application version backup confirmation and sends a confirmation message to the backup data management module.

If the backup space is not occupied, the operation of backup of the application version can be continuously executed. The application version backup confirmation can be performed, and the confirmation message is sent to the backup data management module.

S12042, the backup detection module prompts a user whether the data already stored in the application backup space needs to be replaced with the data of the last version of the upgrade application; or prompting the user whether to increase the application backup space.

When the backup space is full, the backup detection module prompts the user whether the data already stored in the application backup space needs to be replaced by the data of the last version of the upgrade application, so that the user can backup and store the data of the last version of the upgrade application in a mode of replacing the data of other backup application versions. Specifically, the system side responds to an instruction for replacing application version data stored in an application backup space; and replacing the application version data selected by the user with version data before the application for version upgrading is not upgraded.

In some possible implementations, the backup detection module may prompt the user whether to add an application backup space, and the user may store the last version data of the upgraded application into the added application backup space by adding the application backup space. Specifically, the system side responds to an instruction for increasing the application backup space, and increases the application backup space; and backing up version data before version upgrading of the application is not upgraded in the increased application backup space.

And S1205, not backing up the application version.

Referring to fig. 14, fig. 14 is a timing chart of an application version recovery according to an embodiment of the present application.

The process of application version recovery mainly involves interaction of the backup data management module and the backup recovery module with the user, and the backup data management module and the backup recovery module may be two modules in the "set" application. The method specifically comprises the following steps:

s1401, the user triggers an application version recovery operation.

The user can select one application from the ' set ' application version backup ' interface, and long-press the application can pop up the ' restore ' button, and after the user clicks the ' restore ' button, the version restore operation of the application is triggered.

S1402, the backup data management module obtains the backup data of the application version and analyzes the data.

After triggering the operation of backup and restoration of a certain application version by a user, the backup data management module acquires and analyzes the backup data of the application version under a specified directory so as to facilitate the subsequent operation of restoring the application version.

S1403, the backup recovery module uninstalls the current version of the application.

After the user triggers the application version recovery operation, the backup recovery module starts unloading the current version data of the application in response to an instruction for recovering the application version data. This step may be performed before step S1402, after step S1402, or both S1402 and S1403. The embodiment of the present application will be described with the step S1403 performed as an example after the step S1402.

S1404, the backup recovery module reads the data analyzed by the backup data management module and installs the backup version of the application.

The backup restoring module reads the backup application version data analyzed by the backup data management module, and installs the backup version of the application, namely, restores the application by adopting the backup application version data.

S1405, the backup recovery module informs the user that the installation is successful.

After the backup recovery module successfully installs the version of an application backup, the backup application version can be prompted to the user in a popup window mode to be successfully installed.

The method provided by the embodiment of the application supports that when the unstable condition occurs after the application is upgraded, the user can restore the application to the stable version backed up before, and the problem that the use experience of the user is affected due to the instability of the application after the upgrade is avoided.

In some possible implementations, the user may also perform a delete operation on the saved application version. Specifically, the user may select the displayed second application in the "application version backup" option interface in the "setting" interface, and after the "delete" option is popped up by the bullet box, the user clicks the "delete" option, and the system side may delete the version data backed up by the second application.

The embodiment also provides an electronic device, which includes: a processor and a memory;

one or more computer programs are stored in the memory, the one or more computer programs comprising instructions; the instructions, when executed by the processor, cause the electronic device to perform the application backup method described in the above embodiments.

The present embodiment also provides a computer-readable storage medium, where the computer-readable storage medium includes instructions that, when executed on an electronic device, cause the electronic device to perform the relevant method steps described in the foregoing embodiments, so as to implement the application backup method described in the foregoing embodiments.

The present embodiment also provides a computer program product comprising instructions which, when run on an electronic device, cause the electronic device to perform the relevant method steps as in fig. 8-14 to implement the method of the above embodiments.

In the scheme provided by the embodiment of the application, backup of application version data is realized mainly by adopting the following steps:

and detecting whether the version upgrade is performed by the application in real time at the system side.

When the application performs version upgrading, if the application performing version upgrading is an application with the use frequency exceeding a preset frequency standard in a preset time period, prompting a user to perform application version data backup operation; that is, when the updated application is detected to be a common application, the user is prompted to backup the application version data.

After the user triggers the version data backup operation on the upgraded application, the system side responds to the application version data backup operation triggered by the user to backup version data before the application with the version upgrade is not upgraded. Therefore, whether the application is upgraded or not can be automatically detected, when the upgrading of the common application is detected, a user is prompted to backup the application version data, and when the situation that the version is unstable after the upgrading of the common application occurs, the user can timely fall back to the version which is stable before, and the user experience is not affected. The application can be screened in a targeted manner, and the storage space is not wasted.
