Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

In this embodiment, a data migration method is proposed. The implementation of the method can depend on a computer program, and the computer program can run on a computer system based on the von Neumann system. The computer program can be a terminal and a terminal. Data migration applications between mobile phones, such as mobile phone changing applications, mobile phone moving applications and other applications. The computer system may be a server or terminal such as a smart phone, a tablet computer, a personal computer, etc. running the above-mentioned computer program.

Specifically, as shown in FIG. 1, the above data migration method includes the following steps S102-S108:

Step S102: After accessing the migration source terminal, acquire a file list on the migration source terminal.

In this embodiment, the execution terminal is the target migration terminal of data migration, that is to say, in this embodiment, the data on the migration source terminal is transferred to the local target migration terminal, for example, during the data migration In the process, the data on the old mobile phone is copied to the new mobile phone intact, the old mobile phone is the migration source terminal, and the new mobile phone is the target migration terminal.

Before data migration, it is first necessary to establish a communication connection between the migration terminal and the target migration source terminal. For example, the communication connection between the target migration terminal and the migration source terminal can be Bluetooth, wifi, NFC or wired connection, that is to say , the data on the migration source terminal can be migrated to the local target migration terminal through the above communication connection.

For example, in one embodiment, after the new mobile phone as the target migration terminal and the old mobile phone as the migration source terminal respectively enter the data migration applications such as "mobile phone move" installed on the terminals, the new and old mobile phones can be directly communication connection.

It should be noted that, in this embodiment, after the communication connection between the target migration terminal and the migration source terminal is established, the user can preview the data on the old mobile phone on the new mobile phone. Specifically, after the target migration terminal accesses the migration source terminal, the target migration terminal obtains the file list on the migration source terminal through the communication connection with the migration source terminal, and the file list is the file list of all files to be migrated .

Step S104: Acquire a locally stored first migration record, determine an untransferred file in the file list according to the first migration record, and add it to the untransferred list.

In this embodiment, if data migration has been performed between the target migration terminal and the migration source terminal before the current data migration, and the data migration is terminated due to the disconnection of the communication connection or the user's initiative to terminate the data migration, etc. Or the data migration is not completely completed. In this case, a migration record is generated on the local target migration terminal and the migration record corresponds to the previous data migration history between the target migration terminal and the migration source terminal. According to the above migration record, the data that has been migrated between the target migration terminal and the migration source terminal and the data that has not yet been migrated can be determined.

The migration record stored in the local destination migration terminal is the first migration record. According to the first migration record, it can be determined from the file list on the migration source terminal obtained in the file list that the transferred files that have undergone data migration and the files in the file list have been migrated. For the untransferred files in the file list that have not yet undergone data migration, after determining the untransferred files in the above file list, all untransferred files are added to the untransferred list.

It should be noted that, in this embodiment, the above-mentioned untransferred list may also be displayed on the display interface of the target migration terminal. For example, in the corresponding operation interface, the untransferred list display component is displayed, wherein the untransferred list display component is displayed. The component is used to display the transfer list corresponding to the files that have not yet been migrated. And, after the data migration of a certain untransferred file is completed, the file is deleted from the above untransferred list.

Step S106: Read the file on the migration source terminal according to the untransferred list and store it locally.

According to each untransferred file included in the untransferred list, read the untransferred files from the migration source terminal one by one, and pass the read untransferred files through the communication connection between the target migration terminal and the migration source terminal The data is stored locally on the migration terminal, that is, the data migration of the untransferred file is completed.

Step S108: Update the first migration record.

In this embodiment, each time the data migration of a file is completed, the record corresponding to the corresponding data migration is updated in the first migration record, that is, the first migration record is the migration progress of the data migration recorded in real time.

It should be noted that the above operation steps are aimed at the situation where the first migration record is stored on the local target migration terminal. No data migration has been performed between), it is not necessary to determine the untransferred files in the file list according to the first migration record, but all files in the file list are determined as untransferred files.

Specifically, in one embodiment, the above method further includes: when the first migration record is not stored locally, reading the file on the migration source terminal according to the file list and storing it locally; generating a migration record, The migration record is used to record the data migration record of storing the file on the migration source terminal locally, and the migration record is stored locally as the first migration record.

That is to say, if data migration is performed for the first time between the target migration terminal and the migration source terminal, the data migration is directly performed one by one according to the file list on the migration source terminal obtained in step S102, and a migration record is generated to record the target at the same time. The data migration progress between the migration terminal and the migration source terminal and the specific migration data situation.

It should be noted that the migration record is not only saved on the target migration terminal, but also saved on the migration source terminal.

Specifically, in an embodiment, after generating the migration record, the method further includes: sending the migration record as a second migration record to the migration source terminal; monitoring whether an update event occurs in the migration record, and after monitoring the migration record When the update event of the migration record is detected, the updated migration record is sent to the migration source terminal as the updated second migration record, and the migration source terminal sends the updated migration record to the migration source terminal according to the received updated second migration record. 2. Migration records are updated.

That is to say, when the migration record is generated, the migration record is also sent to the migration source terminal for storage by the migration source terminal, and every time the migration record is updated, the migration record stored on the migration source terminal is updated. The synchronization is updated, that is, the synchronization of the migration records on the migration source terminal and the target migration terminal is ensured.

Further, in order to improve the readiness and integrity of the re-migration data in the case of re-migration during the data migration process, it is also necessary to verify the migration records stored on the target migration terminal and the migration source terminal respectively.

Specifically, before the step of determining the untransferred files in the file list according to the migration records and adding them to the untransferred list, the step further includes: acquiring a second migration record on the migration source terminal; judging the first migration records Whether the record is consistent with the second migration record; if so, the step of determining an untransferred file in the file list according to the first migration record and adding it to the untransferred list is performed.

That is, only when the second migration record stored on the migration source terminal is consistent with the first migration record stored on the local target migration terminal, the above-mentioned determining according to the first migration record is performed directly in the file list. The step of adding the untransferred file to the untransferred list. In this case, because the first migration record and the second migration record are consistent, the first migration record or the second migration record is used as the basis for determining the untransferred file. The basic effect is the same.

Further, if the second migration record stored on the migration source terminal is not consistent with the first migration record stored on the local target migration terminal, further determination is required, and it is determined that the process of determining the untransferred file is based on the first migration record. The first migration record is also the second migration record.

Specifically, after the step of judging whether the first migration record and the second migration record are consistent, the step further includes: when the first migration record is inconsistent with the second migration record, obtaining the locally stored file Stored file list; determine whether the stored file list is consistent with the transferred file in the first migration record; when the stored file list is consistent with the transferred file in the first migration record, execute the The first migration record determines the untransferred file in the file list and adds it to the untransferred list; when the stored file list is inconsistent with the transferred file in the first migration record, it is determined that the stored file Whether the file list is consistent with the transferred file in the second migration record, when the stored file list is consistent with the transferred file in the second migration record, determine the file according to the second migration record The untransferred files in the list are added to said untransferred list.

That is to say, if the second migration record stored on the migration source terminal is not consistent with the first migration record stored on the local target migration terminal, it is necessary to determine the second migration record stored on the migration source terminal and the local target migration record. Whether there is a certain migration record in the transferred file recorded in the first migration record stored on the terminal is consistent with the file stored on the local target migration terminal, it means that the migration record is the same as the file stored on the target migration terminal. Therefore, the untransferred files in the file list obtained in the above step S102 should be determined according to the migration record.

That is to say, even if the data migration is suspended during the data migration process, the original unfinished data migration can be continued according to the migration record next time, which increases the operational flexibility during the data migration process and avoids the need for data migration in the process of data migration. This improves the integrity of the migrated data due to the defect of insufficient data integrity caused by the suspension of data migration.
