[0125] In the following description, specific details such as specific system structures and technologies are provided for illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application can also be implemented in other embodiments without these specific details.

[0126] It should be understood that when used in the present specification and the appended claims, the term "comprising" indicates the presence of described features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0127] It should also be understood that in the embodiments of the present application, "one or more" refers to one, two or more than two; "and / or" describes the association relationship of associated objects, indicating that three relationships may exist; for example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B may be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0128] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", "fourth", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0129] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0130] The data migration method across user spaces provided in the embodiment of the present application can be applied to electronic devices such as tablet computers, mobile phones, laptop computers, ultra-mobile personal computers (UMPCs), netbooks, personal digital assistants (PDAs), etc. The embodiment of the present application does not limit the specific type of electronic devices.

[0131] Figure 1 The schematic diagram of the structure of an electronic device is shown. The electronic device 100 may include a processor 110, an external memory interface 120, an internal memory 121, a universal serial bus (USB) interface 130, a charging management module 140, a power management module 141, a battery 142, an antenna 1, an antenna 2, a mobile communication module 150, a wireless communication module 160, an audio module 170, a speaker 170A, a receiver 170B, a microphone 170C, an earphone interface 170D, a sensor module 180, a button 190, a motor 191, a camera 193, a display screen 194, and a subscriber identification module (SIM) card interface 195, etc. Among them, the sensor module 180 may include a pressure sensor 180A, a touch sensor 180K, etc.

[0132] It is to be understood that the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the electronic device 100. In other embodiments of the present application, the electronic device 100 may include more or fewer components than shown in the figure, or combine some components, or split some components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

[0133] The processor 110 may include one or more processing units, for example, the processor 110 may include an application processor (AP), a modem processor, a graphics processor (GPU), an image signal processor (ISP), a controller, a memory, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU), etc. Different processing units may be independent devices or integrated into one or more processors.

[0134] The controller may be the nerve center and command center of the electronic device 100. The controller may generate an operation control signal according to the instruction operation code and the timing signal to complete the control of fetching and executing instructions.

[0135] The processor 110 may also be provided with a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may store instructions or data that the processor 110 has just used or cyclically used. If the processor 110 needs to use the instruction or data again, it may be directly called from the memory. This avoids repeated access, reduces the waiting time of the processor 110, and thus improves the efficiency of the system.

[0136] The internal memory 121 can be used to store computer executable program codes, and the executable program codes include instructions. The processor 110 executes various functional applications and data processing of the electronic device 100 by running the instructions stored in the internal memory 121. The internal memory 121 may include a program storage area and a data storage area. Among them, the program storage area can store an operating system and an application required for at least one function (such as a sound playback function, an image playback function, etc.).

[0137] In addition, the internal memory 121 may include a high-speed random access memory and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, a universal flash storage (UFS), etc.

[0138] The embodiments of the present application do not particularly limit the specific structure of the execution subject of a method for data migration across user spaces, as long as the code of a method for data migration across user spaces according to the embodiments of the present application can be run to perform processing according to a method for data migration across user spaces provided by the embodiments of the present application. For example, the execution subject of a method for data migration across user spaces provided by the embodiments of the present application may be a functional module in an electronic device that can call and execute a program, or a processing device applied to an electronic device, such as a chip.

[0139] As user demands increase, the functions of smart electronic devices become more and more powerful, and people become more and more dependent on electronic devices. Users can use electronic devices for work, life, and other related activities. As an example, users can store data (e.g., documents, videos, audio, pictures, etc.) in electronic devices or perform related processing on the stored data. Among the data stored by users, there are some important data or confidential data. In order to ensure the security of important data and confidential data, a more secure storage method is needed to store important data or confidential data.

[0140] In this regard, dual systems (also referred to as dual user spaces) or multiple systems (multiple user spaces) are set up in some electronic devices. The systems in the electronic devices are independent of each other and do not communicate with each other. Applications can be installed in each system, data can be stored, etc. For the sake of convenience, this application takes the existence of two systems in an electronic device as an example for explanation, and for the sake of convenience, this application refers to one system as the first system and the other system as the second system; or, one system is referred to as the main user space and the other system is referred to as the sub-user space.

[0141] At present, when there are two systems in an electronic device, due to the independence of the two systems and the fact that they are set in the same electronic device, the data between the two systems cannot interact directly, that is, the data in one system cannot be directly migrated to another system. If the user needs to migrate data from one system to another system, it is necessary to use another electronic device or the data transmission capabilities of certain applications to achieve data migration across user spaces, which brings inconvenience to the user. Data migration refers to copying or cutting data in one user space to another user space.

[0142] In one embodiment, if Figure 2 The method shown is to achieve data migration across user spaces with the help of another electronic device. Figure 2 There are a main user space and a sub-user space in the first electronic device, and the data in the main user space in the first electronic device needs to be migrated to the sub-user space in the first electronic device as an example for explanation.

[0143] Specifically, the user enables the main user space in the first electronic device, and shares or sends the migration data that needs to be migrated in the main user space in the first electronic device to the second electronic device. For example, the first electronic device transmits the migration data to the second electronic device via Bluetooth, and the second electronic device stores the migration data after receiving it. The user enables the sub-user space in the first electronic device, and uses the second electronic device to share or send the stored migration data to the sub-user space in the first electronic device, so that the sub-user space of the first electronic device contains data migrated from the main user space of the first electronic device, thereby achieving the purpose of transmitting data from the main user space to the sub-user space in an electronic device. If it is necessary to migrate data from the sub-user space in the first electronic device to the main user space, the data can also be transmitted with the help of the second electronic device according to the above method, which will not be repeated here.

[0144] In another embodiment, a method for data migration across user spaces is implemented with the help of a data transmission function of an application in an electronic device. Figure 3 There are a main user space and a sub-user space in the electronic device, and there is a first WeChat application in the main user space, and the first WeChat application uses a first account to log in; there is a second WeChat application in the sub-user space, and the second WeChat application uses a second account to log in.

[0145] Specifically, when the user uses the main user space of the electronic device, he opens the first WeChat application and sends the migration data that needs to be migrated to the second account under the first WeChat application. After the user enters the sub-user space and opens the second WeChat application, the migration data sent by the first account can be received, so that the migration data sent by the main user space exists in the sub-user space of the electronic device, thereby achieving the purpose of transmitting data from the main user space to the sub-user space in an electronic device. Of course, in actual use, applications other than WeChat can also be used to migrate data across user spaces, such as QQ applications or DingTalk applications.

[0146] In another embodiment, if Figure 4 The method shown is to achieve data migration across user spaces with the help of Baidu Netdisk. Figure 4 There are main user space and sub-user space in the electronic device. When the user uses the main user space of the electronic device, the migration data to be migrated is uploaded to Baidu Cloud through Baidu Netdisk for storage. When the user uses the sub-user space of the electronic device, the migration data is downloaded from Baidu Cloud through Baidu Netdisk, so that the sub-user space obtains the migration data migrated from the main user space, realizing the purpose of transmitting data from the main user space to the sub-user space in an electronic device.

[0147] It can be seen that the existing methods of realizing data migration across user spaces all require the use of another electronic device or the introduction of other accounts for data transmission. The data transmission efficiency of using another electronic device for data transmission is low, and the security of data cannot be guaranteed when introducing other accounts for data transmission. In addition, for data transmission using cloud space, the transmission between the electronic device and the server is designed, and the data transmission efficiency is low. Moreover, when data migration across user spaces is carried out with the help of another electronic device or with the help of the data transmission capabilities of certain applications, only pictures or videos can be transmitted between the two systems, and locally cached application data and setting data cannot be transmitted. In addition, when performing data migration across user spaces according to the current method, batch transmission of data cannot be performed, the data transmission efficiency is low, and the security is relatively low.

[0148] In view of this, in order to achieve the effect of direct data transmission between two systems in the same electronic device, this application proposes a data migration method across user spaces, which can achieve data migration across user spaces on a single device without the need for other accounts or servers. Figure 5 As shown, the electronic device displays when in use Figure 5 (a) interface in the Figure 5 The interface (a) in FIG. 1 displays the options of “moving data out” and “moving files in”. If the user needs to migrate data across user spaces, the user can click the option of “moving data out” or “moving files in”. In response to the user clicking the option of “moving data out”, the electronic device displays Figure 5 (b) interface, Figure 5 The (b) interface in the figure shows the data categories that can be migrated across users, such as pictures, videos, audio, text, third-party applications, and self-developed applications. Users can Figure 5 In the (b) interface, select the data category that needs to be migrated, for example, Figure 5 In the (b) interface, after the user clicks on pictures, videos, third-party applications and self-developed applications, the options of pictures, videos, third-party applications and self-developed applications are in a selected state. In response to the user clicking on the "OK" option, the electronic device displays Figure 5 (c) interface, Figure 5 The (c) interface shows pictures, videos, third-party applications, and self-developed applications that can be moved. Users can Figure 5 In the (c) interface, select the data to be migrated, for example, Figure 5 In the interface (c), after the user selects picture 1, video 1, WeChat and YOYO, picture 1, video 1, WeChat and YOYO are in a selected state. In response to the user clicking the "migration" option, the electronic device performs a data migration operation across user spaces.

[0149] Among them, third-party applications are applications installed in electronic devices that are not developed by the manufacturer of the electronic device, such as WeChat applications, Weibo applications, and Baidu applications, etc. Self-developed applications are applications developed by the manufacturer of the electronic device installed in the electronic device, such as YOYO applications, etc.

[0150] Specifically, when there are multiple systems (user spaces) in an electronic device, a data migration module (also referred to as a data migration service or data migration middleware) for performing data transmission across user spaces is provided in each system (also referred to as each user space), so as to facilitate the use of the data migration module to perform data migration across user spaces. For ease of explanation, take the case where there are two systems (two user spaces) in an electronic device as an example, where one user space is called the main user space and the other user space is called the sub-user space. A data migration module is provided in the main user space of the electronic device, and a data migration module is provided in the sub-user space of the electronic device. The data migration modules in the same electronic device can communicate with each other to realize the mutual transmission of data in different user spaces.

[0151] Take the migration of data from the main user space to the sub-user space as an example. Figure 6As shown, the electronic device backs up the migration data that needs to be migrated in the main user space to the data migration module in the main user space, and the data migration module in the main user space sends the migration data to be migrated to the data migration module in the sub-user space. After the data migration module in the sub-user space receives the migration data sent by the data migration module in the main user space, it restores the migration data to the corresponding position for storage. In this application, the migration data may include file data, third-party application data, self-developed application data, and system setting data. Among them, the file data may include pictures, videos, audio, and text, etc., and the process of file data migrating from one system to another may be a copying process. The third-party application data is the data of the third-party application, and the third-party application data may include the installation package of the third-party application, cached data, application setting data (such as WeChat chat background picture), etc., and the cached data may include chat records and local cache information (such as cached video), etc. The self-developed application data is the data in the self-developed application, and the self-developed application data may include the installation package of the self-developed application, cached data, application setting data, etc. The system setting data may include the desktop wallpaper of the electronic device, the display language of the electronic device, the text display font, the text display font size, etc. The data migration of third-party application data, self-developed application data, and system setting data includes the data backup process and the data recovery process. The third-party application data, self-developed application data, and system setting data are backed up in the main user space, and the backed-up third-party application data, self-developed application data, and system setting data are sent to the sub-user space; after the sub-user space receives the third-party application data, self-developed application data, and system setting data, the third-party application data, self-developed application data, and system setting data are restored in the sub-user space.

[0152] Below, before introducing the method of the present application, the software system of the electronic device involved in the embodiment of the present application is described. The software system of the electronic device can adopt a layered architecture, an event-driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. The embodiment of the present application takes the Android system with a layered architecture as an example to exemplify the software system of the electronic device.

[0153] Figure 7 is a block diagram of a software system of an electronic device provided in an embodiment of the present application. Figure 7 The layered architecture divides the software into several layers, each with clear roles and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into three layers, from top to bottom, namely, the application layer, the system service layer, and the system framework layer.

[0154] The application layer may include a series of application packages, and the application layer may receive user operations. Figure 7As shown, the application layer may include a setting application, a first application, a second application, a third application, a fourth application, and the like. Among them, the first application and the second application are self-developed applications, such as "intelligent voice assistant application" and "smart life application". The third application and the fourth application are third-party applications installed in electronic devices, such as "Baidu application", "WeChat application", etc. There is a decoupling module in both the first application and the second application. There is a backup and recovery module (backup agent module) in both the third application and the fourth application. The functions of the decoupling module and the backup agent module are similar, and both are used to back up and restore data in the corresponding application. Specifically, the decoupling module of the first application is used to back up and restore data that can be backed up in the first application. The decoupling module of the second application is used to back up and restore data that can be backed up in the second application. The backup and recovery module of the third application is used to back up and restore data in the third application. The backup and recovery module of the fourth application is used to back up and restore data in the fourth application. The setting application is a system application, and the setting application is used to set the functions of the electronic device.

[0155] The system service layer may include a data migration module and a cloning module, wherein the data migration module is used to send the data that needs to be migrated in the system to the data migration module of other systems to achieve data migration across user spaces; the cloning module is used to collect the data that needs to be migrated in the system and store the data that needs to be migrated in the cloning module so that the data migration module can obtain the data that needs to be migrated from the cloning module. For example, the cloning module can collect application data and file data, etc. In addition, the cloning module can also process the data that needs to be migrated, such as compression and encryption.

[0156] The system framework layer may include a backup manager service module (BMS module) and a content provider for file data (provider module, which may also be called a file providing module). Among them, the BMS module is used to transmit data or instructions between the clone module and the backup agent module of the application. For example, the data of the first application backed up in the backup agent module of the first application is forwarded to the clone module for processing through the BMS module. The provider module is used to provide stored file data, such as pictures, audio, video, and text.

[0157] It should be noted that the structure of each system in the electronic device can adopt the above Figure 7 For example, the main user space and the sub-user space both use the above Figure 7In the system architecture, when the main user space and the sub-user space perform data migration across user spaces, the data migration module in the main user space communicates with the data migration module in the sub-user space to achieve data migration between the two user spaces.

[0158] Next, a method for data migration across user spaces proposed in this application is described.

[0159] When an application is installed in the first system but not in the second system, the first system can directly send the installation package of the application to the second system so that the second system can install the application, eliminating the need for the user to search and download the installation package. The migration method for the installation package of the application includes:

[0160] The first system receives a data migration instruction, which is used to instruct the first system to migrate an installation package of an application (first application) to the second system. The application is a third-party application and / or a self-developed application, and can also be other applications.

[0161] The first system sends an installation package of an application to the second system. The data of the application can be recorded as application data, and the application data can include the installation package, local cache data (also known as cache data), and application setting data. The local cache data (also known as cache data) and application setting data can also be recorded as the first information.

[0162] After the second system receives the installation package of the application sent by the first system, the second system installs the corresponding application in the second system.

[0163] Next, a method of data migration will be described when the same application is installed in the first system and the second system.

[0164] like Figure 8 As shown, when the user uses the first system, the electronic device displays Figure 8 (a) interface in the Figure 8 In the interface (a) of FIG. 1 , the option of “moving out data” is displayed. If the user needs to migrate data across user spaces, the user can click the option of “moving out data”. After receiving the operation of the user clicking the option of “moving out data”, the electronic device displays Figure 8 (b) interface, Figure 8The (b) interface in the figure shows the categories of data that can be migrated across user spaces, such as pictures, videos, audio, documents, third-party applications, and self-developed applications. If the user needs to migrate data in a third-party application, the user can click the "Third-party Application" option. After receiving the user's click on the "Third-party Application" option, the third-party application option of the electronic device is selected; the user clicks the "OK" option, and the electronic device displays Figure 8 (c) interface, Figure 8 The (c) interface in the figure shows the third-party applications that can be migrated across user spaces, such as WeChat, QQ, and Weibo. The user can select the third-party application that needs to be migrated. For example, if the user needs to migrate the data in the WeChat application, the user clicks "WeChat" and the WeChat application is displayed as selected. Figure 8 After the user selects a third-party application, the user can click the "Migrate" option. After receiving the user's operation of clicking the "Migrate" option (data migration operation), the electronic device generates a data migration instruction and sends the data migration instruction to the data migration module in the first system. In actual use, the user can select multiple third-party applications at the same time to achieve simultaneous migration of data of multiple third-party applications. For example, the user can select Figure 8 "WeChat Application" and "QQ Application" in the (c) interface.

[0165] In actual applications, users select Figure 8 After selecting the WeChat application on the (c) interface, the types of data that can be migrated in WeChat can also be displayed, such as WeChat application setting data, WeChat chat history, local cache data in WeChat, etc., so that the user can select the category of data to be migrated.

[0166] Combine the following Figure 8 , describes the method of migrating data from third-party applications across user spaces. Fig. 9 As shown, Fig. 9 FIG. 4 shows the process of migrating data in a third-party application A (a second application) across user spaces.

[0167] S11, a data migration module in the first system receives a data migration instruction, where the data migration instruction includes key information (second information) of the data to be migrated.

[0168] The first system may be a main user space or a sub-user space, which is not limited here. The data to be migrated is application data in a third-party application A.

[0169] If the data to be migrated is data in a third-party application A, the key information of the data to be migrated may include the application name or application identifier of the third-party application A, the installation time, the type identifier of the data to be migrated selected by the user, etc. For example, the type identifier of the chat record may be "A1", the type identifier of the application setting data may be "A2", etc., and the type identifier may be set as needed.

[0170] S12, the data migration module in the first system sends a data migration instruction to the clone module in the first system.

[0171] S13, after the cloning module in the first system receives the data migration instruction, the cloning module in the first system determines that the data to be migrated belongs to the data of the third-party application according to the key information in the data migration instruction.

[0172] Specifically, since the key information includes the application name or application identifier of the third application A, the cloning module can determine the application that needs to migrate data based on the application name or application identifier in the key information, query the category of the application that needs to migrate data to which it belongs, and determine that the application that needs to migrate data belongs to a third-party application; or, the category identifier of the application that needs to migrate data is carried in the key information, and the category identifier is used to characterize whether the application for the data to be migrated belongs to a third-party application or a self-developed application. For example, if the application that needs to migrate data is a third-party application, the key information carries the category identifier "1" of the third application.

[0173] As an example, the key information includes "WeChat", and the cloning module can determine that the data in WeChat needs to be migrated based on the key information. The cloning module can also determine that the category to which WeChat belongs is a third-party application.

[0174] Specifically, after determining that the data to be migrated is data in the third-party application A, the cloning module can also query the data query path of the third-party application that needs to be migrated, and write the data query path of the third-party application A into the key information of the third-party application A in the data migration instruction. For example, if the data in WeChat needs to be migrated, the cloning module can query the data query path of WeChat, and write the data query path corresponding to WeChat into the key information corresponding to WeChat.

[0175] S14, the clone module in the first system sends a data migration instruction to the BMS module in the first system.

[0176] S15, after the BMS module in the first system receives the data migration instruction, the BMS module in the first system determines that the data to be migrated is data in the third-party application A according to key information in the data migration instruction.

[0177] In another embodiment, if the data migration instruction carries a data query path, after receiving the data migration instruction, the BMS module in the first system may send the data migration instruction to the third-party application A according to the data query path in the data migration instruction.

[0178] S16, the BMS module in the first system sends a data migration instruction to the backup agent module of the third-party application A in the first system.

[0179] S17, after the backup agent module of the third-party application in the first system receives the data migration instruction, the backup agent module retrieves / collects the first data (application data) in the third-party application A, where the first data is the data in the third-party application A that can be migrated.

[0180] Specifically, when the key information in the data migration instruction includes the type identifier of the data to be migrated, the backup agent module of the third-party application in the first system collects the first data according to the type identifier of the data to be migrated.

[0181] In this embodiment, the first data may include application setting data in the third-party application A, local cache data, chat records, etc.

[0182] S18, the backup agent module of the third-party application A in the first system sends the first data to the BMS module in the first system.

[0183] In this embodiment, the backup agent module of the third-party application A packages the first data and sends the packaged first data to the BMS module in the first system.

[0184] When packaging the first data, the first data may also be tagged, and the tag of the first data contains the corresponding key information of the first data, so that after receiving the first data, the second system can parse which application the first data should be restored to. The key information of the first data is the same as the key information of the data to be migrated. For example, if the first data is a chat record in WeChat, the key information in the first data is "WeChat".

[0185] S19, after the BMS module in the first system receives the first data, the BMS module in the first system sends the first data to the clone module in the first system.

[0186] S20, after receiving the first data, the cloning module in the first system backs up the first data to obtain a backup address of the first data.

[0187] Specifically, after receiving the first data, the cloning module may process the first data, for example, the cloning module compresses and / or encrypts the first data to obtain the processed first data. The cloning module backs up the processed first data to obtain the backup address of the first data. In this embodiment, compressing the first data can reduce the storage space occupied by the first data, thereby achieving the purpose of saving storage space. In addition, encrypting the first data can ensure the storage and transmission security of the first data.

[0188] S21, the cloning module in the first system sends the backup address of the first data to the data migration module of the first system.

[0189] In another implementation, the above step S20 may also be: after receiving the first data, the cloning module sends the first data to the data migration module of the first system. Alternatively, after processing the first data, the cloning module sends the processed first data to the data migration module of the first system.

[0190] S22, after receiving the backup address of the first data, the data migration module of the first system obtains the first data from the cloning module in the first system according to the backup address of the first data.

[0191] Alternatively, after receiving the backup address of the first data, the data migration module of the first system sends a data query instruction to the clone module of the first system, and the data query instruction includes the backup address of the first data. After receiving the data query instruction, the clone module of the first system queries the first data according to the backup address in the data query instruction, and the clone module of the first system sends the first data to the data migration module of the first system.

[0192] S23, after the data migration module of the first system obtains the first data, the data migration module of the first system sends the first data to the data migration module of the second system.

[0193] In this embodiment, the first data may also be compressed data, encrypted data, or compressed and encrypted data.

[0194] The following is combined with Fig.10 , a process of restoring the first data after the second system receives the first data is described.

[0195] S31, the data migration module in the second system receives the first data sent by the data migration module in the first system, where the first data is data in the third-party application A.

[0196] The first data carries key information of the first data.

[0197] S32, the data migration module in the second system sends the first data to the storage module in the second system so that the storage module in the second system stores the first data and obtains the storage address of the first data, and the storage module in the second system sends the storage address of the first data to the data migration module in the second system.

[0198] S33, the data migration module in the second system receives the storage address of the first data sent by the storage module, and the data migration module in the second system generates a data recovery instruction based on the storage address of the first data.

[0199] The data recovery instruction includes the storage address of the first data and key information of the first data.

[0200] S34, the data migration module of the second system sends a data recovery instruction to the clone module in the second system.

[0201] S35, after receiving the data recovery instruction, the cloning module in the second system determines, according to the data recovery instruction, that the first data is data in a third-party application.

[0202] Specifically, the method for determining that the first data is data in a third-party application includes:

[0203] Since the data recovery instruction carries the key information of the first data, after receiving the data recovery instruction, the cloning module in the second system can determine that the first data is data in a third-party application according to the key information of the first data in the data recovery instruction.

[0204] S36, the clone module in the second system sends a data recovery instruction to the BMS module in the second system.

[0205] S37, after the BMS module in the second system receives the data recovery instruction, the BMS module in the second system determines that the first data is data in the third-party application A according to the data recovery instruction.

[0206] In this embodiment, the method for the BMS module to determine that the first data is data in the third-party application A is the same as the above step S35. Please refer to the description of step S35, which will not be repeated here.

[0207] S38, the BMS module in the second system sends a data recovery instruction to the backup agent module of the third-party application A to which the first data belongs.

[0208] S39, after the backup agent module of the third-party application A in the second system receives the data recovery instruction, it obtains the first data from the storage module according to the storage address of the first data in the data recovery instruction, and restores the first data to the third-party application A to obtain first result information (data recovery result), and the first result information is used to indicate whether the recovery of the first data is successful.

[0209] In this embodiment, after the backup agent module of the third-party application A receives the data recovery instruction, it extracts the key information in the data recovery instruction and verifies the key information to determine whether the first data in the data recovery instruction belongs to its own application data. For example, the key information of the first data is "WeChat". After the backupagent module of the third-party application A receives the data recovery instruction, it determines that "WeChat" in the key information is its own application name, and then determines that the first data in the data recovery instruction belongs to its own application data, and can restore the first data.

[0210] S40, the backup agent module of the third-party application A in the second system sends first result information to the BMS module in the second system.

[0211] S41, after the BMS module in the second system receives the first result information, the BMS module in the second system sends the first result information to the clone module in the second system.

[0212] S42: After the cloning module in the second system receives the first result information, the cloning module in the second system sends the first result information to the data migration module in the second system.

[0213] S43, after the data migration module in the second system receives the first result information, the data migration module in the second system sends the first result information to the data migration module in the first system.

[0214] In this embodiment, after receiving the first result information, the data migration module in the first system sends the first result information to the application layer of the first system for display, so that the user can understand whether the first data migration is successful.

[0215] In the above, after the second system receives the first data, the first data is stored, and the storage address of the first data is transmitted between the modules of the second system, which can reduce the data transmission amount and increase the data transmission speed.

[0216] In another achievable manner, the first data may be directly transmitted between the modules of the second system, including:

[0217] After executing step S31, the data migration module in the second system generates a data recovery instruction according to the first data, and the data recovery instruction includes the first data. Execute steps S34 to S38. After receiving the data recovery instruction, the backup agent module in the second system extracts the first data in the data recovery instruction, recovers the first data and obtains the first result information. Execute steps S40 to S43.

[0218] When transmitting the first data, if the first data is encrypted and / or compressed data, the cloning module in the second system may decrypt and / or decompress the first data.

[0219] Secondly, combined Fig.11 , a method for migrating data in a self-developed application across user spaces is described. Specifically, a method for migrating data in a self-developed application B (a third application) across user spaces is described as an example.

[0220] S51, the data migration module in the first system receives a data migration instruction, wherein the data migration instruction includes key information (second information) of the data to be migrated. The data to be migrated is application data of the self-developed application B.

[0221] In this embodiment, the self-developed application B is a self-developed application that needs to perform data migration. The key information of the data to be migrated includes the application name or application identifier of the self-developed application, the type identifier of the data to be migrated (setting data, cache data, etc.), etc.

[0222] S52: The data migration module in the first system sends a data migration instruction to the clone module in the first system.

[0223] S53, after the cloning module in the first system receives the data migration instruction, the cloning module in the first system determines that the data to be migrated is the data of the self-developed application B according to the key information in the data migration instruction.

[0224] Specifically, the cloning module determines that the data to be migrated is data of the self-developed application B according to the key information of the data to be migrated in the data migration instruction.

[0225] S54, the cloning module in the first system sends a data migration instruction to the decoupling module of the self-developed application B.

[0226] S55, after the decoupling module of the self-developed application B in the first system receives the data migration instruction, the decoupling module of the self-developed application B in the first system collects the second data in the self-developed application B, and the second data is the data in the self-developed application B that needs to be migrated.

[0227] The second data may include application setting data, local cache data, historical query data, etc.

[0228] S56, the decoupling module of the self-developed application B in the first system sends second data to the clone module in the first system.

[0229] In this embodiment, the second data includes key information of the second data, so that the second system can determine the location where the second data should be restored after receiving the second data. The key information of the second data is the same as the key information of the data to be migrated in step S51.

[0230] S57, after the cloning module in the first system receives the second data, the cloning module in the first system backs up the second data to obtain a backup address of the second data.

[0231] In another embodiment, after the cloning module in the first system receives the second data, the cloning module in the first system sends the second data to the data migration module of the first system.

[0232] In another embodiment, after receiving the second data, the cloning module in the first system processes the second data, for example, the cloning module compresses and / or encrypts the second data to obtain processed second data. The cloning module in the first system sends the processed second data to the data migration module of the first system.

[0233] In another embodiment, after receiving the second data, the clone module in the first system processes the second data to obtain the processed second data. The clone module in the first system backs up the processed second data to obtain the storage address of the second data.

[0234] S58, the cloning module in the first system sends the backup address of the second data to the data migration module in the first system.

[0235] S59, after the data migration module in the first system receives the backup address of the second data, the data migration module in the first system reads the second data from the clone module of the first system according to the backup address of the second data.
