Detailed Description

For a better understanding of the technical solutions of the present application, embodiments of the present application are described in detail below with reference to the accompanying drawings.

It should be understood that the described embodiments are merely some, but not all, of the embodiments of the present application. All other embodiments, based on the embodiments herein, which would be apparent to one of ordinary skill in the art without making any inventive effort, are intended to be within the scope of the present application.

The terminology used in the embodiments of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be understood that the term "and/or" as used herein is merely one way of describing an association of associated objects, meaning that there may be three relationships, e.g., a and/or b, which may represent: the first and second cases exist separately, and the first and second cases exist separately. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

Referring to fig. 1, a schematic application scenario is provided in an embodiment of the present application. In fig. 1 two terminal devices, a new handset and an old handset, are shown. The old mobile phone can be understood as a mobile phone used by a user in daily life, and the new mobile phone can be understood as a mobile phone purchased by the user newly. The old mobile phone stores more user data, and the user needs to transfer all or part of the user data in the old mobile phone to the new mobile phone so as to facilitate the use of the new mobile phone by the user, namely, the old mobile phone transfers the data to the new mobile phone.

It should be noted that, fig. 1 illustrates a mobile phone as an example, and should not be taken as a limitation of the protection scope of the present application. In addition to the mobile phone, the terminal may be a tablet computer, a personal computer (personal computer, PC), a personal digital assistant (personal digital assistant, PDA), a smart watch, a netbook, a wearable electronic device, an augmented reality (augmented reality, AR) device, a Virtual Reality (VR) device, a vehicle-mounted device, a smart car, a smart sound, a robot, smart glasses, a smart television, or the like.

In addition, the old and new devices performing data migration may be the same type of terminal device, or may be different types of terminal devices, which is not specifically limited in the embodiment of the present application.

Referring to fig. 2, a schematic diagram of a data migration scheme in the related art is shown. In fig. 2, two terminal devices of a new mobile phone and an old mobile phone are shown, and a user needs to migrate a file to be migrated in the old mobile phone to the new mobile phone. Firstly, storing files to be migrated on an old mobile phone in a temporary folder on a new mobile phone, and then moving the files to be migrated in the temporary folder to a corresponding target path to realize data migration. The temporary folder is a temporary storage position of the file to be migrated in the new mobile phone, and the target path is a final storage position of the file to be migrated in the new mobile phone. Different files to be migrated may have different target paths, for example, the target paths corresponding to video files, document files, and picture files are different.

However, in the data migration scheme shown in fig. 2, two write operations are required for the file to be migrated. Specifically, a write operation is carried out in the process of storing the file to be migrated in the temporary folder; and performing write operation once in the process of moving the file to be migrated from the temporary folder to the target path. This process increases overhead, such as taking up more data processing resources, outputting storage resources, and extending data migration time.

Based on the problem, the embodiment of the application provides a data migration method, a terminal, a storage medium and a program product, which are beneficial to solving the problem that in the prior art, two write operations are needed to be performed on files to be migrated, and the system overhead is increased.

Referring to fig. 3, a flow chart of a data migration method according to an embodiment of the present application is provided. The method can be applied to the application scenario shown in fig. 1. The first terminal may be understood as an old mobile phone, i.e. a data migration end or a data export end, and the second terminal may be understood as a new mobile phone, i.e. a data migration end or a data import end. As shown in fig. 3, it mainly includes the following steps.

Step S301: the second terminal transmits the target path to the first terminal.

In this embodiment of the present application, after a communication connection is established between a first terminal serving as a data migration end and a second terminal serving as a data migration end, the second terminal sends a target path to the first terminal, that is, notifies the first terminal of a storage location of a file to be migrated. It can be understood that the target path is the final storage location of the file to be migrated in the second terminal. The target path may be allocated after the second terminal receives the file description information to be migrated of the first terminal, or may be a plurality of target paths pre-designated by the second terminal system.

The files to be migrated under different types, sizes or source paths may have different target paths, for example, different types of files, such as video files, document files, and picture files, corresponding to different target paths. The second terminal may also specify a target path according to the service logic, e.g. the same type of file in the data of different applications may have different target paths. In one possible implementation manner, the second terminal sends the target path to the first terminal, which specifically includes: the second terminal sends M target paths to the first terminal, wherein M is more than or equal to 2. That is, the second terminal transmits a plurality of target paths to the first terminal to correspond to the files to be migrated under a plurality of types or source paths of the first terminal; the sent information can also contain the corresponding relation between the description information of the files to be migrated and the target paths.

It should be noted that, the second terminal may send multiple target paths to the first terminal at the same time, or may send the multiple target paths to the first terminal sequentially, which is not specifically limited in the embodiment of the present application.

Step S302: and the first terminal generates a file path mapping relation according to the target path and the file information to be migrated.

Specifically, after receiving a target path sent by a second terminal, the first terminal generates a file path mapping relation according to the target path and corresponding file information to be migrated, wherein the file path mapping relation comprises a corresponding relation between the target path and the file information to be migrated. Specifically, the second terminal may allocate a corresponding target path to the file to be migrated according to the type, size or source path of the file to be migrated, that is, establish a mapping relationship between the file to be migrated and the target path. It can be understood that the file information to be migrated corresponds to the file to be migrated, and after the corresponding relationship between the target path and the file information to be migrated is determined, the corresponding relationship between the target path and the file to be migrated can be determined. The file information to be migrated may be identification information of the file to be migrated, for example, a name, a category, etc. of the file to be migrated, which is not particularly limited in the embodiment of the present application.

In one possible implementation, the number of target paths is M, the number of files to be migrated is N, M is greater than or equal to 2, and N is greater than or equal to 2. In the application scene, a file path mapping relation is required to be generated according to M target paths and N files to be migrated, wherein the file path mapping relation comprises corresponding relations of M target paths and N file information to be migrated, namely, the corresponding relation between each target path and the files to be migrated is established.

Referring to fig. 4, a schematic diagram of a mapping relationship of a file path is provided in an embodiment of the present application. In fig. 4, 3 target paths and 3 file information to be migrated (file information to be migrated is used to match corresponding files to be migrated) are shown. As shown in fig. 4, in the file path mapping relationship, the first target path corresponds to the second file information to be migrated, that is, the second file to be migrated corresponding to the second file information to be migrated needs to be stored in the storage area corresponding to the first target path; the second target path corresponds to the information of the third file to be migrated, namely the third file to be migrated corresponding to the information of the third file to be migrated needs to be stored in a storage area corresponding to the second target path; the third target path corresponds to the first file information to be migrated, that is, the first file to be migrated corresponding to the first file information to be migrated needs to be stored in the storage area corresponding to the third target path.

It should be noted that fig. 4 is only one possible implementation listed in this application, and should not be taken as limiting the scope of protection of this application. For example, in one possible implementation, the target path and the file information to be migrated may not be in a one-to-one correspondence.

Referring to fig. 5, another schematic diagram of mapping relationships between file paths is provided in an embodiment of the present application. In fig. 4, 3 target paths and 4 file information to be migrated are shown. The second target path corresponds to the third file information to be migrated and the fourth file information to be migrated, that is, the third file to be migrated corresponding to the third file information to be migrated and the fourth file to be migrated corresponding to the fourth file information to be migrated are stored in the storage area corresponding to the second target path.

Step S303: the first terminal sends migration data to the second terminal.

Referring to fig. 6, a schematic data structure of migration data is provided in an embodiment of the present application. As shown in fig. 6, the migration data includes a destination address field and a user data field, where the user data field is used to carry a file to be migrated, such as a video file, a picture file, and/or a document file. The destination address field is used for bearing a target path corresponding to the file to be migrated. It is noted that the destination address is used to characterize the storage location in the second terminal after the user data has been transferred to the second terminal.

In the embodiment of the application, when the migration data is transmitted, the destination address field is set as the target path corresponding to the file to be migrated, and after receiving the file to be migrated, the second terminal directly stores the file to be migrated in the corresponding target path. That is, the data migration is completed only by performing one write operation, and the system performance overhead is reduced.

Specifically, when two or more files to be migrated exist, migration data corresponding to each file to be migrated is sequentially sent to the second terminal. If the bandwidth is allowed, a plurality of files to be migrated and corresponding migration data can be simultaneously sent to the second terminal.

Step S304: and the second terminal stores the file to be migrated in a target path corresponding to the file to be migrated.

Referring to fig. 7, a schematic diagram of a data migration scenario is provided in an embodiment of the present application. The data migration scene corresponds to the file path mapping relationship shown in fig. 5, and as shown in fig. 7, the first terminal sequentially sends migration data corresponding to the first file to be migrated, the second file to be migrated and the third file to be migrated to the second terminal. Specifically, in migration data corresponding to the first file to be migrated, a destination address field is set as a third target path, the migration data is sent to the second terminal, and after the second terminal receives the migration data, the first file to be migrated is stored in a storage area corresponding to the third target path according to the third target path in the destination address field. Similarly, the second files to be migrated are sequentially stored in the storage area corresponding to the first target path, and the third files to be migrated are stored in the storage area corresponding to the second target path.

In the embodiment of the application, when the first terminal sends the migration data to the second terminal, the destination address of the migration data can be dynamically adjusted, corresponding destination addresses are provided for different files to be migrated, instead of all the files being placed under a unified destination path, so that the files to be migrated are directly stored in the corresponding destination addresses, secondary write operation in the second terminal is avoided, and system overhead is saved.

In some possible implementations, the target path sent by the second terminal to the first terminal may be a path preset by the second terminal according to different file types. For example, a storage location of a picture file is preset as a first target path, a storage location of a video file as a second target path, a storage location of a document file as a third target path, and so on.

In another possible implementation, the first terminal and the second terminal may determine the target path through data negotiation prior to data migration.

Referring to fig. 8, a flow chart of another data migration method according to an embodiment of the present application is provided. As shown in fig. 8, the method further includes the following steps, prior to S301, on the basis of the embodiment shown in fig. 3.

Step S801: and the first terminal sends the file description information to be migrated to the second terminal.

In this embodiment of the present application, after the first terminal and the second terminal establish communication connection, the first terminal first sends description information of a file to be migrated, for example, size information, type information and/or source path information of the file to be migrated, to the second terminal.

The size information refers to the size of the data volume of the file to be migrated, and may be, for example, 50m,1g, etc. It can be appreciated that the storage space of the target path corresponding to the file to be migrated should be greater than or equal to the data size, so as to prevent the storage of the file to be migrated from being unable to be completed. That is, the second terminal can conveniently allocate the target path meeting the storage space requirement for the file to be migrated through the size information.

The type information refers to the type of the file to be migrated, and the same or similar target paths can be allocated to the files to be migrated of the same type. In some possible implementations, the files to be migrated may be divided into picture files, video files, and document files. It should be noted that, in different application scenarios, the classification manners of the files to be migrated are different, and the embodiment of the present application does not limit the specific types of the files to be migrated.

The source path information refers to a storage path of the file to be migrated in the first terminal. According to the method and the device for determining the target path, the first terminal sends the source path information to the second terminal, and the second terminal preferentially determines the target path according to the source path information, so that after data migration is completed, the storage position of the file to be migrated accords with the original use habit of a user as much as possible.

Step S802: and the second terminal determines a target path according to the file description information to be migrated.

After receiving the description information of the file to be migrated, the second terminal can allocate a target path meeting the requirement for the file to be migrated according to the description information of the file to be migrated, and then can send the target path and the corresponding relation between the target path and the description information of the file to be migrated to the first terminal. Because the file to be migrated is matched with the file description information to be migrated, the corresponding relation between the target path and the file to be migrated, namely the mapping relation of the file path, can be determined according to the corresponding relation between the target path and the file description information to be migrated.

In practical application, the first terminal may keep the corresponding relation between the target path sent by the second terminal and the file description information to be migrated, or modify the corresponding relation, and generate the file path mapping relation according to the mapping rule of the second terminal.

For example, the target path meets one or a combination of the following conditions:

1. when the file description information to be migrated comprises size information of the file to be migrated, a target path is allocated to the file to be migrated according to the size information, and a storage space corresponding to the target path is larger than or equal to the size of the file to be migrated.

2. And when the file description information to be migrated comprises the type information of the file to be migrated, distributing a target path matched with the type of the file to be migrated. For example, if the file to be migrated is a picture file, in the second terminal, the picture file is stored in the first target path, and then the first target path is allocated to the file to be migrated.

3. When the file description information to be migrated includes a source path of the file to be migrated, it may be prioritized that the same target path as the source path is allocated to the file to be migrated. If the second terminal does not have the same target path as the source path, other target paths are allocated to the file to be migrated.

It should be noted that, the above description information of the files to be migrated is only one possible implementation manner listed in the embodiments of the present application, and those skilled in the art may set other description information of the files to be migrated according to actual needs, which is not particularly limited in the embodiments of the present application.

By adopting the technical scheme provided by the embodiment of the application, before data migration, the first terminal and the second terminal carry out data negotiation, so that a target path which is more in line with the actual application scene can be determined.

It can be understood that by adopting the above data migration scheme, for each file to be migrated, the second terminal needs to send a target path to the first terminal, then establish a file path mapping relationship according to the target path, and then send migration data corresponding to each file to be migrated to the second terminal in turn.

However, in practical applications, there may be some files to be migrated that are relatively small, for example, the size of the files to be migrated may be only a few KB or a few MB "small files", and using the above data processing method for each "small file" obviously increases the overhead. Based on this, the embodiment of the application also provides another data migration method.

Referring to fig. 9, a flowchart of another data migration method according to an embodiment of the present application is provided. The method further comprises the following steps on the basis of the embodiment shown in fig. 3.

Step S901: the method comprises the steps that a first terminal packages two or more files to be migrated, and a file package corresponding to the two or more files to be migrated is generated.

In a specific implementation, a threshold value of a file size may be preset, two or more files to be migrated, which are smaller than or equal to the threshold value of the size, are packaged, a corresponding file package is generated, and data migration is performed in the form of the file package, where the file package may be a compressed package.

It should be noted that, for files to be migrated smaller than or equal to the size threshold, it is not necessary to configure the target path in advance in the first terminal and the file path mapping relationship, so that overhead can be saved.

Step S902: and the first terminal sends migration data corresponding to the file package to the second terminal.

Because the file package contains a plurality of files to be migrated, the file package needs to be stored in a temporary folder of the second terminal first, and then the files to be migrated in the file package are respectively moved to corresponding target paths. Specifically, a user data field carrying file package of migration data is set, a destination address field carrying file package of the migration data is set to correspond to a temporary path, the destination address can be determined by the second terminal and then sent to the first terminal, and different temporary paths can be designated for file packages of different types of files to be migrated.

Step S903: and the second terminal stores the file packet in a temporary path corresponding to the file packet.

Because the destination address in the migration data is a temporary path corresponding to the file packet, the second terminal stores the file packet in the temporary path, that is, in a folder corresponding to the temporary path after receiving the file packet.

Step S904: and the second terminal moves the files to be migrated in the file package to a target path corresponding to the files to be migrated.

After the file package is stored in the temporary folder, the second terminal can respectively move the files to be migrated in the file package to the corresponding target paths. The target path may be a path allocated by the second terminal according to the type of the file to be migrated or other information; or, path information carried in the migration data may also be used. This is not particularly limited in the embodiments of the present application.

In a specific implementation, if the file package is a compressed package, the compressed package is decompressed, and then the decompressed file to be migrated is moved to a target path corresponding to the file to be migrated.

In the embodiment of the application, the files to be migrated with smaller data quantity are packaged, data migration is performed in a file package mode, the configuration of the mapping relationship between the target path and the file path is avoided for each small file, and the system overhead can be saved.

In one possible application scenario, the file to be migrated may include an application file, and application data corresponding to the application file. The application program file may be understood as an installation package corresponding to an application program of a case in the terminal, such as a mailbox; application data may be understood as specific data generated by a user when using an application, such as mail in a mailbox.

The application data may be migrated in the manner shown in fig. 3. However, the application data is generally stored under the installation directory of the application file, so before the application data is migrated in the manner shown in fig. 3, the application file needs to be migrated first, then the application is installed in the second terminal, and further, a target path corresponding to the application data is determined.

Referring to fig. 10, a flowchart of another data migration method according to an embodiment of the present application is provided. In this implementation, the file to be migrated includes application data corresponding to the application file, and the target path includes a target path corresponding to the application data, and before step S301 shown in fig. 3, the following steps are further included.

Step S1001: and the first terminal sends migration data corresponding to the application program file to the second terminal. Before application data migration, application files are first migrated. Because the application file needs to be installed, the application file may be stored in a temporary folder, that is, a destination address field of the migration data is set as a temporary path corresponding to the application file, and in addition, a user data field of the migration data is set as the application file. Of course, the application program file may also be stored in other locations of the second terminal, which is not specifically limited in the embodiment of the present application.

Step S1003: and the second terminal determines a target path corresponding to the application data according to the installation directory of the application program file.

Typically, application data needs to be stored under the installation directory of the application file, i.e. the corresponding location of the installation directory. Therefore, after the installation directory of the application program file is generated, the embodiment of the application program determines the target path corresponding to the application data according to the installation directory.

In a subsequent step, the migration of application data is implemented by using the method in the embodiment shown in fig. 3.

Referring to fig. 12, a flowchart of another data migration method according to an embodiment of the present application is provided. The method shown in fig. 12 includes a first terminal and a second terminal, where the first terminal is a data migration device, i.e. an old terminal; the second terminal is a data migration device, i.e. a new terminal. Both the first terminal and the second terminal may adopt the software structure shown in fig. 11, as shown in fig. 12, which mainly includes the following steps.

Step S1201: and the user selects the file to be migrated from the file selection interface of the first terminal.

In the embodiment of the application, the first terminal is a data migration terminal, and the user can select the file to be migrated in the file selection interface of the first terminal, and trigger a file selection instruction to be migrated.

Referring to fig. 13, a schematic diagram of a file selection and receiving interface is provided in an embodiment of the present application. As shown in 13 (a) in fig. 13, a list of a plurality of files (file 1, file 2, file 3, file 4, file 5 and file 6) is stored in the first terminal, and may be selected according to a file type, a source path, a size, or a specific file, and the user may select a file to be migrated, that is, a file to be migrated to the second terminal, from among the files stored in the first terminal. For example, the user may select file 2 as the file to be migrated by triggering the region in which file 2 is located. Of course, the user may also select multiple files as files to be migrated, for example, all files under a certain path, which is not limited in the embodiment of the present application.

Step S1202: and sending a file selection instruction to be migrated to a file path management module of the first terminal.

After the user selects the file to be migrated through the file selection interface, the file selection instruction to be migrated is sent to the file path management module. The file to be migrated selection instruction may include selected file description information to be migrated, where the file description information to be migrated may be size information, type information and/or source path information of the file to be migrated.

For example, if the file 2 in 13 (a) is selected as the file to be migrated, the file description information to be migrated in the file to be migrated selection instruction may include size information, type information and/or source path information of the file 2.

Step S1203: the file path management module of the first terminal sends a target path request instruction to the sending module.

And after receiving the file selection instruction to be migrated, the file path management module of the first terminal sends a target path request instruction to the sending module so that the sending module sends the target path request instruction to the second terminal.

The target path request instruction comprises file description information to be migrated.

Step S1204: the sending module of the first terminal sends a target path request instruction to the receiving module of the second terminal.

And after receiving the target path request instruction, the sending module of the first terminal sends the target path request instruction to the receiving module of the second terminal.

Step S1205: the receiving module of the second terminal sends a target path request instruction to the file path management module of the second terminal.

And after receiving the target path request instruction, the receiving module of the second terminal sends the target path request instruction to the file path management module of the second terminal, so that the file path management module determines a target path according to the file description information to be migrated in the target path request instruction.

Step S1206: the file path management module of the second terminal determines a target path.

After receiving the target path request instruction, the file path management module of the second terminal can determine a target path according to the file description information to be migrated in the target path request instruction.

For example, when the file description information to be migrated includes size information of the file to be migrated, a target path is allocated to the file to be migrated according to the size information, and a storage space corresponding to the target path is greater than or equal to the size of the file to be migrated.

And when the file description information to be migrated comprises the type information of the file to be migrated, distributing a target path matched with the type of the file to be migrated. For example, if the file to be migrated is a picture file, in the second terminal, the picture file is stored in the first target path, and then the first target path is allocated to the file to be migrated.

When the file description information to be migrated includes a source path of the file to be migrated, it may be preferentially considered that a target path identical to the source path is allocated to the file to be migrated at the second terminal. If the second terminal does not have the same target path as the source path, other target paths are allocated to the file to be migrated.

Step S1207: the file path management module of the second terminal sends the target path to the sending module.

The file path management module of the second terminal may send the target path to the sending module after completing the allocation of the target path, so that the sending module sends the target path to the first terminal.

It should be noted that the target path may be one or more. The method and the device can determine a plurality of target paths corresponding to the plurality of files to be migrated at the same time, and the sending information comprises the target paths corresponding to the description information of the plurality of files to be migrated.

Step S1208: the transmitting module of the second terminal transmits the target path to the receiving module of the first terminal.

And after receiving the target paths, the sending module of the second terminal sends the target paths corresponding to the plurality of file description information to be migrated to the first terminal, and specifically, sends the target paths to the receiving module of the first terminal.

Step S1209: the receiving module of the first terminal sends the target path to the file path management module.

After receiving the target paths, the receiving module of the first terminal sends the target paths corresponding to the plurality of file description information to be migrated to the file path management module so that the file path management module generates corresponding file path mapping relations according to the target paths.

Step S1210: the file path management module of the first terminal generates a file path mapping relation.

And after receiving the target path, the file path management module of the first terminal generates a file path mapping relation according to the corresponding relation between the target path and the file description information to be migrated. The file path mapping relation comprises a corresponding relation between a target path and file information to be migrated, wherein the file description information to be migrated can be file size, file type or source path, and can also be file name, identification and the like.

Step S1211: and triggering a file transmission instruction to be migrated on the file selection interface by a user.

After the file path mapping relation is generated, file transmission to be migrated can be performed. Specifically, the user may trigger a file transfer instruction to be migrated at the file selection interface.

Step S1212: and sending a file transmission instruction to a backup service module of the first terminal.

After the file selection interface triggers the file transmission instruction to be migrated, the user can send the file transmission instruction to be migrated to the backup service module.

Step S1213: the file path management module of the first terminal sends the file path mapping relation to the backup service module.

When the file to be migrated is sent, the destination address corresponding to the file to be migrated needs to be determined according to the file path mapping relation, so that the file path mapping relation needs to be sent to the backup service module.

Of course, the backup service module may also query the file path management module for the target path corresponding to the file to be migrated according to the file to be migrated, which is not limited in particular in the embodiment of the present application.

Step S1214: and the backup service module of the first terminal determines a destination address corresponding to the file to be migrated according to the file path mapping relation.

The backup service module may determine a destination address corresponding to the file to be migrated according to the file path mapping relationship, or may query the file path management module for a destination path corresponding to the file to be migrated, which is not specifically limited in the embodiment of the present application.

The destination address is a target path corresponding to the file to be migrated. For example, in the file path mapping relationship shown in fig. 4, the first target path corresponds to the second file to be migrated, and the destination address corresponding to the second file to be migrated is the first target path.

Step S1215: the transmitting module of the first terminal transmits the migration data to the receiving module of the second terminal.

In this embodiment of the present application, the data structure of the migration data includes a destination address field and a user data field, the user data field of the migration data is set as a file to be migrated, and the destination address field of the migration data is set as a target path corresponding to the file to be migrated.

Step S1216: and the receiving module of the second terminal stores the file to be migrated to a target path corresponding to the destination address.

That is, after receiving the file to be migrated, the second terminal directly stores the file to be migrated in the corresponding target path, and completes data migration only by performing write operation once, thereby reducing system performance overhead.

Step S1217: and the receiving module of the second terminal sends migration information of the file to be migrated to the file receiving interface.

In a specific implementation, after receiving the file to be migrated, the receiving module may send migration information of the file to be migrated to the receiving interface, so that a user knows a data migration state. The migration information may be information such as a file name, a file thumbnail, or a file migration progress, which have been migrated, and the embodiment of the present application is not specifically limited.

Referring to 13 (b) in fig. 13, the file receiving interface corresponds to the file selecting interface shown in 13 (a), the user selects the file 2 and the file 4 as files to be migrated in the file selecting interface shown in 13 (a), and after the migration of the file is completed, icons of the file 2 and the file 4 are displayed in the file receiving interface of the second terminal shown in 13 (b), so as to inform the user of the completed data migration state, and improve user experience.
