[0021] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and cannot be understood as limiting the embodiments of the present application.

[0022] See also Figure 1 and Figure 2 , the embodiment of the present application provides a data synchronization method, the data synchronization method comprising:

[0023] Step 011: When the data to be synchronized is written, create a synchronization task;

[0024] Specifically, the data to be synchronized may be data generated during the operation of the electronic device 100, for example, picture data or video data generated during shooting by the electronic device 100, game data and chat information data generated during gaming or chatting by the electronic device 100, etc. A large amount of data may be generated during the operation of the electronic device 100, which may occupy a large amount of storage space of the electronic device 100, or the data generated by the electronic device 100 may need to be backed up to prevent data loss, etc., and the data generated by the electronic device 100 may need to be synchronized, wherein the electronic device 100 includes a processor 30 and a memory 40, and the electronic device 100 may be a smart phone, a server, a computer, a tablet computer, a smart watch, a smart wearable device, etc.

[0025] When the data to be synchronized generated by the electronic device 100 is written into the memory 40 of the electronic device 100, the processor 30 of the electronic device 100 can create a synchronization task based on the written data to be synchronized. For example, when the game data generated by the smartphone is written into the memory 40 of the smartphone, the processor 30 in the smartphone can create a synchronization task for synchronizing the game data; or, when the application data generated by the application in the server is written into the memory 40, the processor 30 in the server can create a synchronization task for synchronizing the application data.

[0026] Step 012: Execute a synchronization task to synchronize the data to be synchronized to the target electronic device 200 in an asynchronous manner.

[0027] The target electronic device 200 is a device that stores data to be synchronized. For example, the target electronic device 200 may also be a smart phone, a server, a computer, a tablet computer, a smart watch, a smart wearable device, etc.

[0028] Specifically, after the synchronization task of the data to be synchronized is created, the processor 30 can execute the created synchronization task, and synchronize the data to be synchronized in the synchronization task to the target electronic device 200 in an asynchronous manner.

[0029] For example, the electronic device 100 is a smart phone, and the target electronic device 200 is a server. When the processor 30 of the smart phone executes a synchronization task to synchronize game data, the processor 30 of the smart phone synchronizes the game data in the synchronization task in an asynchronous manner. That is, when the processor 30 of the smart phone synchronizes each game data in the synchronization task to the server, there is no need to wait for the notification of whether the synchronization of the game data is completed to be transmitted to the processor 30 of the smart phone. The processor 30 of the smart phone can then synchronize the next game data to the server, and synchronize the remaining game data in sequence.

[0030] For another example, the electronic device 100 is a server and the target electronic device 200 is a smart phone. When the server's processor 30 executes a synchronization task to synchronize application data, the server's processor 30 synchronizes the application data in the synchronization task in an asynchronous manner. That is, when the server's processor 30 synchronizes each application data in the synchronization task to the smart phone, there is no need to wait for the notification of whether the synchronization of the application data is completed to be transmitted to the server's processor 30. The server's processor 30 can then synchronize the next application data to the smart phone, and synchronize the remaining application data in sequence.

[0031] In this way, by creating a synchronization task in the electronic device 100 and executing the created synchronization task when the data to be synchronized is written into the memory 40 of the electronic device 100, the timeliness of the synchronization is guaranteed; and compared with synchronizing the data to be synchronized in a synchronous manner, it is necessary to wait for the target electronic device 200 to send back a notification that the synchronization of the data to be synchronized is completed before the next synchronization of the data to be synchronized can be performed, synchronizing one or more data to be synchronized in the synchronization task to the target electronic device 200 in an asynchronous manner can improve the synchronization efficiency of the data to be synchronized, and further improve the timeliness of synchronizing the data to be synchronized to the target electronic device 200, taking into account both the timeliness and efficiency of data synchronization.

[0032] See also Figure 4 In some implementations, before executing the synchronization task, the data synchronization method further includes:

[0033] Step 013: Determine whether the preset synchronization task queue is empty;

[0034] Step 014: If yes, add the synchronization task to the synchronization task queue, and update the target synchronization timestamp of the synchronization task queue according to the maximum timestamp corresponding to all the data to be synchronized of the synchronization task. The data to be synchronized of the synchronization task includes all the data to be synchronized between the local synchronization timestamp and the target synchronization timestamp. The local synchronization timestamp is the maximum timestamp of the synchronized data.

[0035] Step 015: If not, update the target synchronization timestamp of the synchronization task queue according to the maximum timestamp.

[0036] Specifically, before executing a synchronization task, the processor 30 of the electronic device 100 needs to determine whether the previous synchronization task is completed. If it is determined that the previous synchronization task is completed, the processor 30 can execute the steps of the current synchronization task; if the previous synchronization task is not completed, the electronic device 100 needs to wait for the previous synchronization task to be completed before executing the steps of the current synchronization task.

[0037] Optionally, the processor 30 can add the created synchronization task to the synchronization task queue, and different synchronization task queues can correspond to different types of data to be synchronized. For example, the data to be synchronized can be game data, chat data, or shooting data, etc. Game data, chat data, or shooting data each correspond to a different synchronization task queue, thereby achieving classified data synchronization of different data. Before executing a synchronization task, the processor 30 of the electronic device 100 needs to judge the preset synchronization task queue to determine whether the preset synchronization task queue is empty, that is, whether there is an unfinished synchronization task.

[0038] When the processor 30 determines that the synchronization task queue is empty, the processor 30 can add the current synchronization task to the synchronization task queue, and update the target synchronization timestamp of the synchronization task queue according to the maximum timestamp of all the timestamps corresponding to the data to be synchronized in the current synchronization task. Each piece of data to be synchronized has a timestamp, and the timestamp corresponding to the data to be synchronized can be the time information when the data to be synchronized is written into the electronic device 100, and the target synchronization timestamp can be the writing time of the last data to be synchronized in the current synchronization task (i.e., the maximum timestamp of all the timestamps corresponding to the data to be synchronized).

[0039] When executing a synchronization task, the data to be synchronized can be sorted in order from small to large timestamps, and then the part that needs to be synchronized in the synchronization task is all the data to be synchronized between the local synchronization timestamp and the target synchronization timestamp, wherein the local synchronization timestamp can be the maximum timestamp of the synchronized data in the previous synchronization task, or the timestamp of the data to be synchronized that has been synchronized by the electronic device 100 the most recently. For electronic devices 100 (such as smart phones and servers), there are corresponding local synchronization timestamps.

[0040] When the processor 30 determines that the preset synchronization task queue is not empty, that is, there are unfinished synchronization tasks, the processor 30 can determine the maximum timestamp of all the data to be synchronized of the current synchronization task, and use the maximum timestamp to update the target synchronization timestamp of the current synchronization task queue. Since the synchronization task queue synchronizes all the data to be synchronized between the local synchronization timestamp and the target synchronization timestamp when performing data synchronization, the current synchronization task and the unfinished synchronization tasks are merged into the same synchronization task, and data synchronization is performed centrally, thereby improving synchronization efficiency.

[0041] In this way, by determining whether the preset synchronization task queue is empty, and when the preset synchronization task queue is not empty, merging the previous synchronization task and the current synchronization task into the same synchronization task for processing, the synchronization efficiency of the data to be synchronized can be improved.

[0042] See also Figure 5 In some implementations, step 012: executing a synchronization task includes:

[0043] Step 0121: Transmit all the data to be synchronized of the synchronization task to the target electronic device 200 through one or more synchronization operations.

[0044] Specifically, when the processor 30 is executing a synchronization task, when the number of data to be synchronized is large enough, because the number of synchronized data to be synchronized is restricted by the hardware of the electronic device 100, all the data to be synchronized in the synchronization task cannot be synchronized to the target electronic device 200 at one time, so the processor 30 needs to synchronize the data to be synchronized multiple times. At this time, the number of synchronized data to be synchronized by the processor 30 is synchronized according to the maximum number of synchronized data that the electronic device 100 can synchronize. For example, the number of data to be synchronized in the synchronization task is 100, and the maximum number of synchronized data to be synchronized by the electronic device 100 is 30. Then the processor 30 synchronizes 30 data to be synchronized each time, and completes the synchronization task through 4 synchronization operations. When the number of data to be synchronized is small enough, the processor 30 can synchronize all the data to be synchronized in the synchronization task to the target electronic device 200 at one time. For example, the number of data to be synchronized in the synchronization task is 10, and the maximum number of synchronized data to be synchronized by the electronic device 100 is 30. Then the processor 30 synchronizes 10 data to be synchronized, and completes the synchronization task through 1 synchronization operation.

[0045] In this way, by performing one or more synchronization operations on the data to be synchronized and transmitting all the data to be synchronized of the synchronization task to the target electronic device 200, the synchronization efficiency of synchronizing the data to be synchronized to the target electronic device 200 can be improved.

[0046] See also Figure 6 In some embodiments, the data synchronization method further includes:

[0047] Step 016: Upon receiving a notification that each piece of data to be synchronized has been synchronized successfully, the synchronization task is determined to be completed, and the local synchronization timestamp is updated according to the maximum timestamp corresponding to all the data to be synchronized of the synchronization task. The local synchronization timestamp is the maximum timestamp of the synchronized data.

[0048] When the processor 30 synchronizes all the data to be synchronized in the synchronization task queue, each time a piece of data to be synchronized completes the synchronization operation, the target electronic device 200 will form a notification of successful synchronization for the data to be synchronized that has completed the synchronization operation, and after the synchronization of the current data to be synchronized is completed, the target electronic device 200 will send the notification to the memory 40 of the current electronic device 100 for storage.

[0049] When a notification that each piece of data to be synchronized in the current synchronization task has been successfully synchronized is stored in the memory 40 of the current electronic device 100, the processor 30 of the current electronic device 100 can determine that the current synchronization task is completed, and the processor 30 needs to update the local synchronization timestamp of the current electronic device 100 based on the corresponding maximum timestamp of all the data to be synchronized in the synchronization task, wherein the local timestamp can be the maximum timestamp of the synchronized data.

[0050] For example, taking the electronic device 100 as a smart phone, the target electronic device 200 as a server, and the smart phone synchronizing chat data to the server as an example, when all the data to be synchronized in the current synchronization task queue of the smart phone are synchronized in multiple synchronization operations, each time when one or more chat data corresponding to the synchronization operation is successfully synchronized to the server, the server will form a synchronization success notification based on the successfully synchronized chat data, and send the notification to the smart phone for storage. After all the chat data in the current synchronization task queue have corresponding synchronization success notifications, the processor 30 of the smart phone can determine that the current synchronization task is completed, and update the local synchronization timestamp of the smart phone based on the maximum timestamp corresponding to all the chat data in the server.

[0051] For another example, let the electronic device 100 be a smart phone, the target electronic device 200 be a server, and take the synchronization of game data from the server to the smart phone as an example. When the smart phone receives the data to be synchronized transmitted by the server, it will also send a notification to the server that the transmitted data to be synchronized has been successfully synchronized. Specifically, when all the data to be synchronized in the current synchronization task queue of the server are synchronized in multiple synchronization operations, when one or more game data corresponding to each synchronization operation are successfully synchronized to the smart phone, the smart phone will form a notification of successful synchronization for the successfully synchronized game data, and send the notification to the server for storage. After all the game data in the current synchronization task queue have corresponding notifications of successful synchronization, the server's processor 30 can determine that the current synchronization task is completed, and update the local synchronization timestamp of the server according to the maximum timestamp corresponding to all the game data in the smart phone.

[0052] In this way, when a notification is received that each piece of data to be synchronized is synchronized successfully, the synchronization task is determined to be completed, and the local synchronization timestamp is updated according to the maximum timestamp corresponding to all the data to be synchronized in the synchronization task, thereby ensuring the accuracy of data synchronization.

[0053] See also Figure 7 In some embodiments, the data synchronization method further includes:

[0054] Step 017: upon receiving a notification of synchronization failure of any data to be synchronized, determining that the synchronization task is not completed, and sorting the write timestamps of all the data to be synchronized of the synchronization task to determine the maximum timestamp that is smaller than the write timestamp of the data to be synchronized that failed to be synchronized;

[0055] Step 018: Update the local synchronization timestamp according to the maximum timestamp. The local synchronization timestamp is the maximum timestamp of the synchronized data. The data to be synchronized of the synchronization task includes all data to be synchronized between the local synchronization timestamp and the target synchronization timestamp.

[0056] Specifically, when the target electronic device 200 receives the data to be synchronized, and any of the data to be synchronized fails to synchronize, the target electronic device 200 can determine that the current synchronization task is not completed. At this time, the processor 30 of the current electronic device 100 sorts the write timestamps of all the data to be synchronized in the synchronization task in a small to large manner, so as to determine the maximum timestamp of the write timestamp of the data to be synchronized that fails to synchronize in the current synchronization task. For example, the data to be synchronized can be [5, 7, 9, 12, 15], wherein the data to be synchronized [5, 7, 12, 15] is synchronized and completed, and the data to be synchronized 9 is synchronized and failed. At this time, it can be determined that the current synchronization task has failed, and the write timestamps of the data to be synchronized are sorted in a small to large manner, and the processor 30 can determine that the maximum timestamp of the data to be synchronized 9 that fails to synchronize is 7; when the data to be synchronized [7, 9, 15] is synchronized and completed, and the data to be synchronized 5 fails to synchronize, there is no maximum timestamp of the data to be synchronized 5 that fails to synchronize in the current synchronization task, and at this time, it can be determined that the maximum timestamp in the previous synchronization task is less than the maximum timestamp of the data to be synchronized that fails to synchronize.

[0057] When the processor 30 determines that the maximum timestamp of the data to be synchronized in the current synchronization task is less than the maximum timestamp of the data to be synchronized that failed to synchronize, the local synchronization timestamp of the current electronic device 100 is updated according to the maximum timestamp. The data to be synchronized in the current synchronization task includes all the data to be synchronized between the local synchronization timestamp and the target synchronization timestamp, and the target synchronization timestamp may be the write timestamp of the last data to be synchronized in the current synchronization task.

[0058] See also Figure 8 In some embodiments, the data synchronization method further includes:

[0059] Step 019: Obtain the time difference between the local time and the time of the target electronic device 200; and

[0060] Step 020: Adjust the write timestamp of the synchronized data according to the time difference so that the write timestamp of the synchronized data matches the time of the electronic device 100 .

[0061] Specifically, because the timing accuracy of the current electronic device 100 and the target electronic device 200 is different, there may be an error between the time of the electronic device 100 and the time of the target electronic device 200, and the write timestamp of the data to be synchronized on the current electronic device 100 is not accurate on the target electronic device 200. Therefore, the processor 30 of the current electronic device 100 needs to obtain the local time of the current electronic device 100 and the time of the target electronic device 200, and calculate the time difference between the local time of the current electronic device 100 and the time of the target electronic device 200.

[0062] After obtaining the time difference between the current electronic device 100 and the target electronic device 200, the current electronic device 100 adjusts the write timestamp of each data to be synchronized according to the time difference when performing data synchronization, so that the write timestamp of the synchronized data matches the time of the target electronic device 200.

[0063] For example, taking the current electronic device 100 as a smart phone, the target electronic device 200 as a server, and the smart phone synchronizing the data to be synchronized with the server as an example, by calculating the time difference between the smart phone and the server, the write timestamp of the data to be synchronized for data synchronization of the smart phone is adjusted, so that the write timestamp of the synchronized data received by the server (the data to be synchronized of the smart phone becomes synchronized data after being transmitted to the server) matches the time of the server. The adjustment method is to add the time difference to the write timestamp of the data to be synchronized, or, taking the current electronic device 100 as a server, the target electronic device 200 as a smart phone, and the server synchronizing the data to be synchronized with the smart phone as an example, by calculating the time difference between the smart phone and the server, the write timestamp of the data to be synchronized for data synchronization of the server is adjusted, so that the write timestamp of the synchronized data in the smart phone matches the time of the smart phone.

[0064] Optionally, the server may perform data synchronization in the same manner as step 011 and step 012, taking into account both the timeliness and efficiency of synchronization; or, the server may also transmit the data to be synchronized at a regular interval, for example, the server transmits the data to be synchronized to other electronic devices 100 every 30 minutes, one hour, etc., to avoid frequent data synchronization occupying too many resources; or, the server may perform data synchronization upon receiving a synchronization instruction sent by other electronic devices 100; or, the server may perform data synchronization by triggering a threshold, for example, when a threshold (such as a threshold of half an hour, one hour, etc.) is reached between the local synchronization timestamp of the server and the target synchronization timestamp (the maximum timestamp of the data to be synchronized), data synchronization is performed, thereby performing data synchronization when a large amount of data to be synchronized has accumulated, thereby maximizing the efficiency of data synchronization.

[0065] See also Fig. 9 The data synchronization device 10 of the implementation mode of the present application includes a creation module 11 and an execution module 12. The creation module 11 is used to create a synchronization task when the data to be synchronized is written; and the execution module 12 is used to execute the synchronization task to synchronize the data to be synchronized to the target electronic device 200 in an asynchronous manner.

[0066] The data synchronization device 10 also includes a judgment module 13, which is used to judge whether the previous synchronization task is completed; if so, wait until the previous synchronization task is completed before entering the step of executing the synchronization task; if not, enter the step of executing the synchronization task.

[0067] The execution module 12 is specifically used to transmit all the to-be-synchronized data of the synchronization task to the target electronic device 200 through one or more synchronization operations.

[0068] The data synchronization device 10 also includes a first determination module 14, which is used to determine that the synchronization task is completed when receiving a notification that each data to be synchronized is successfully synchronized, and update the local synchronization timestamp according to the maximum timestamp corresponding to all the data to be synchronized of the synchronization task. The local synchronization timestamp is the maximum timestamp of the synchronized data.

[0069] The data synchronization device 10 also includes a second determination module 15, which is used to determine that the synchronization task is not completed when receiving a notification of synchronization failure of any data to be synchronized, and sort the write timestamps of all the data to be synchronized of the synchronization task to determine the maximum timestamp of the write timestamp of the data to be synchronized that is less than the synchronization failure.

[0070] The data synchronization device 10 also includes an update module 16, which is used to update the local synchronization timestamp according to the maximum timestamp. The local synchronization timestamp is the maximum timestamp of the synchronized data. The data to be synchronized of the synchronization task includes all data to be synchronized between the local synchronization timestamp and the target synchronization timestamp.

[0071] The data synchronization device 10 further includes an acquisition module 17 , which is used to acquire the time difference between the local time and the time of the target electronic device 200 .

[0072] The data synchronization device 10 further includes an adjustment module 18 , which is configured to adjust the write timestamp of the synchronized data according to the time difference, so that the write timestamp of the synchronized data matches the time of the electronic device 100 .

[0073] The data synchronization device 10 further includes a receiving module 19 , which is used to send a notification of successful synchronization of the transmitted data to be synchronized to the target electronic device 200 when receiving the data to be synchronized transmitted by the target electronic device 200 .
