Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In this embodiment, a data migration method is proposed, which may be implemented by relying on a computer program that can run on a computer system based on von neumann architecture, which may be a data migration application between a terminal and a terminal, such as an application for changing a machine, an application for moving a mobile phone, etc. The computer system may be a server or a terminal, such as a smart phone, a tablet computer, a personal computer, etc., running the computer program.
Specifically, as shown in fig. 1, the data migration method includes the following steps S102 to S108:
step S102: and after accessing the migration source terminal, acquiring a file list on the migration source terminal.
In this embodiment, the execution terminal is a target migration terminal for data migration, that is, in this embodiment, data on the migration source terminal is transferred to the local target migration terminal, for example, in the process of data migration, data on an old mobile phone is copied to a new mobile phone without being changed, the old mobile phone is the migration source terminal, and the new mobile phone is the target migration terminal.
Before data migration, a communication connection between the migration terminal and the target migration source terminal needs to be established, for example, the communication connection between the target migration terminal and the migration source terminal may be bluetooth, wifi, NFC, or wired connection, that is, data on the migration source terminal may be migrated to the local target migration terminal through the communication connection.
For example, in one embodiment, after entering a data migration application installed on a terminal, such as "mobile phone moving", respectively, in a new mobile phone as a target migration terminal and an old mobile phone as a migration source terminal, a direct communication connection between the new mobile phone and the old mobile phone may be established.
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 may 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 a file list on the migration source terminal through a communication connection with the migration source terminal, where the file list is a file list of all files to be migrated.
Step S104: and acquiring a first migration record stored locally, determining the file which is not transmitted in the file list according to the first migration record, and adding the file to the file list which is not transmitted.
In this embodiment, if data migration is performed between the target migration terminal and the migration source terminal before data migration is performed this time, and data migration is terminated or is not completely completed due to disconnection of communication connection or active termination of data migration by a user, in this case, a migration record is generated on the local target migration terminal and corresponds to a history of data migration between the previous target migration terminal and the previous migration source terminal. According to the migration record, the data which has been migrated between the target migration terminal and the migration source terminal and the data which has not been migrated can be determined.
The migration record stored in the local target migration terminal is a first migration record, the transferred file subjected to data migration in the file list and the non-transferred file not subjected to data migration in the file list are determined in the file list on the acquired migration source terminal according to the first migration record, and after the non-transferred file in the file list is determined, all the non-transferred files are added to the non-transferred list.
It should be noted that, in this embodiment, the non-transmission list may also be displayed on the display interface of the target migration terminal, for example, a non-transmission list display component is displayed in a corresponding operation interface, where the non-transmission list display component is used to display a transmission list corresponding to a file that has not been subjected to data migration. After the data migration of one of the untransferred files is completed, the file is deleted from the untransferred list.
Step S106: and reading the file on the migration source terminal according to the non-transmission list and storing the file to the local.
And according to each untransmitted file contained in the untransmitted list, reading the untransmitted files from the migration source terminal one by one, and storing the read untransmitted files locally in the migration terminal through the communication connection between the target migration terminal and the migration source terminal, namely finishing the data migration of the untransmitted files.
Step S108: and updating the first migration record.
In this embodiment, each time data migration of one file is completed, a record corresponding to the corresponding data migration is updated in the first migration record, that is, the first migration record is a migration progress of the data migration described in real time.
It should be noted that, in the above operation steps, all cases refer to a case where the first migration record is stored in the local target migration terminal, and if the first migration record is not stored locally (that is, data migration has not been performed between the previous target migration terminal and the migration source terminal), it is not necessary to determine an untransmitted file in the file list according to the first migration record, but all files in the file list are determined as untransmitted files.
Specifically, in an embodiment, the method further includes: when the first migration record is not stored in the local, reading the file on the migration source terminal according to the file list and storing the file in the local; and generating a migration record, wherein the migration record is used for recording a data migration record for storing the file on the migration source terminal to the local, and the migration record is stored to the local as a first migration record.
That is, if data migration is performed between the target migration terminal and the migration source terminal for the first time, data migration is performed one by one directly according to the file list on the migration source terminal acquired in step S102, and a migration record is generated at the same time to record the data migration progress and the specific migration data situation between the target migration terminal and the migration source terminal.
Note that the migration record is stored not only in the target migration terminal but also in the migration source terminal.
Specifically, in an embodiment, after the generating the migration record, the method further includes: sending the migration record serving as a second migration record to the migration source terminal; and monitoring whether the migration record has an update event, and when the update event of the migration record is monitored, sending the updated migration record serving as an updated second migration record to the migration source terminal, wherein the migration source terminal updates the second migration record according to the received updated second migration record.
That is, when the migration record is generated, the migration record is also sent to the migration source terminal, and is stored by the migration source terminal, and when the migration record is updated each time, the migration record stored in the migration source terminal is updated synchronously, that is, the synchronicity of the migration records on the migration source terminal and the migration record on the target migration terminal is ensured.
Further, in order to improve the preparation and integrity of the migration-resumed data when the migration is resumed in the data migration process, it is also necessary to verify the migration records respectively stored in the target migration terminal and the migration source terminal.
Specifically, before the step of determining the untransmitted file in the file list according to the migration record and adding the file to the untransmitted list, the method further includes: acquiring a second migration record on the migration source terminal; judging whether the first migration record is consistent with the second migration record; and if so, executing the step of determining the non-transferred files in the file list according to the first migration record and adding the non-transferred files to the non-transferred list.
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 step of determining the untransmitted file in the file list according to the first migration record and adding the file to the untransmitted list is directly performed, in this case, because the first migration record is consistent with the second migration record, the effect of taking the first migration record or the second migration record as the basis for determining the untransmitted file is consistent.
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 needs to be made to determine whether the second migration record is based on the first migration record or the second migration record in the process of determining that the file is not transferred.
Specifically, after the step of determining whether the first migration record and the second migration record are consistent, the method further includes: when the first migration record is inconsistent with the second migration record, acquiring a storage file list of a local stored file; judging whether the storage file list is consistent with the transmitted files in the first migration record or not; when the storage file list is consistent with the transferred files in the first transfer record, executing the step of determining the non-transferred files in the file list according to the first transfer record and adding the non-transferred files to the non-transferred list; and when the storage file list is not consistent with the transmitted files in the first migration record, judging whether the storage file list is consistent with the transmitted files in the second migration record, and when the storage file list is consistent with the transmitted files in the second migration record, determining the untransmitted files in the file list according to the second migration record and adding the untransmitted files to the untransmitted list.
That is, if the second migration record stored in the migration source terminal does not coincide with the first migration record stored in the local target migration terminal, it is necessary to determine whether any one of the second migration record stored in the migration source terminal and the transferred file recorded in the first migration record stored in the local target migration terminal is consistent with the file stored in the local target migration terminal, which means that the migration record is consistent with the file stored in the target migration terminal, and therefore, the untransmitted file in the file list acquired in the step S102 should be determined according to the migration record.
In an embodiment, as shown in fig. 2, a data migration apparatus is further provided, which includes a file list obtaining module 102, an untransferred list determining module 104, a data migration module 106, and a first migration record updating module 108, where:

That is to say, even if the data migration is suspended in the data migration process, the original unfinished data migration can be continued next time according to the migration record, so that the operation flexibility in the data migration process is increased, the defect of insufficient data integrity caused by the suspension of the data migration in the data migration process is avoided, and the integrity of the migration data is improved.
