The details will be described separately below.

The data synchronization system provided by the embodiment of the invention mainly includes a server and a terminal. The above terminal may be specifically integrated in a mobile terminal such as a tablet computer or a mobile phone. The server and the terminal can be connected through a wired or wireless network.

For example, please refer to FIG. 1. FIG. 1 is a schematic diagram of a scenario of a data synchronization system according to the present invention. The data synchronization device is specifically integrated in a server, and is mainly used to receive a data synchronization instruction sent by a terminal, where the data synchronization instruction carries a cloud account and The data to be synchronized is obtained according to the data synchronization instruction, and the data to be synchronized is de-duplicated according to the backup data to obtain the target to be synchronized data, and the target to be synchronized data is sent to the login terminal that logs in to the cloud account, so that the login terminal is completed. data synchronization.

In addition, as shown in FIG. 1, the data synchronization system may further include a terminal. The data synchronization system can generate a data synchronization instruction and send it to the server, and can also receive the target synchronization data to be synchronized sent by the server, and perform data synchronization.

In the present embodiment, description will be made from the perspective of a data synchronizing apparatus, which may be specifically integrated in a server.

Referring to FIG. 2, FIG. 2 is a schematic flowchart of a data synchronization method according to an embodiment of the present invention. The data synchronization method in this embodiment includes:

Step S101: Receive a data synchronization instruction sent by the terminal.

The data synchronization instruction carries cloud account information and data to be synchronized that needs to be synchronized. In this embodiment, at least two terminals simultaneously log in to the cloud account, and each terminal can perform cloud backup on the server through the cloud account. The above-mentioned data to be synchronized may include an address book, a memo, a short message, a chat record, a picture information, a multimedia information, an application usage record, and the like.

In the embodiment of the present invention, the data synchronization command may be generated by the terminal according to a user operation, or may be automatically generated when the data in the terminal is modified, which is not further limited by the present invention. For example, when a user adds a contact information to the terminal, a prompt box may pop up to prompt the user to synchronize the contact information to other terminals. The user may click the “OK” button on the terminal screen, and the terminal is based on the terminal. The above new contact information generates a data synchronization instruction and sends it to the server.

Step S102, acquiring backup data according to the data synchronization instruction.

The backup data is data that is last backed up by the terminal on the cloud server, where the terminal can be any terminal that logs in to the cloud account.

In an actual application, the server receives a data synchronization instruction sent by the terminal, where the instruction includes data to be synchronized that needs to be synchronized, and most of the data to be synchronized may have been backed up in the server, and only a small part of the data is needed. Synchronized target to be synchronized data. For example, when the terminal adds a contact information, a data synchronization instruction is generated, and the instruction can carry all the contact information stored on the terminal. Synchronizing all contact information as target synchronization data to other terminals will result in a large amount of data duplication and will also consume more server resources. Preferably, the server only needs to filter the newly added one of the contact information, so in the embodiment, the data to be synchronized may be de-screened by the backup data.

Preferably, the data to be synchronized included in the data synchronization instruction received in step S101 may be all data in the terminal, or may be part of data. For example, only the address book information in the terminal is sent to the server as the data to be synchronized. At this time, the server needs to first determine the data type of the synchronization data, and then acquire the backup data corresponding to the data type in step S102. That is, before the data synchronization instruction sent by the terminal is received, and the data is synchronized according to the data synchronization instruction, the method in this embodiment may further include:

Determining the data type of the data to be synchronized;

The steps of obtaining backup data according to the data synchronization instruction specifically include:

The same backup data as the data type is obtained according to the data synchronization instruction.

Step S103, performing deduplication processing on the data to be synchronized according to the backup data to obtain data to be synchronized.

In the embodiment of the present invention, there may be various methods for performing deduplication processing on the data to be synchronized according to the backup data. For example, the data to be synchronized may be divided into a plurality of sub-data according to a certain preset rule, and then it is determined whether the sub-data has the same data sample in the backup data, and if so, the sub-data is determined to be a repetitive sub-data, if not If yes, it is determined that the sub data is the target to be synchronized data that needs to be synchronized. Then, the repeated sub-data in the data to be synchronized is deleted, and the remaining data after the deletion is the target to be synchronized data that needs to be synchronized. The foregoing preset rule may be divided according to a data type, or according to a data size or the like. The method in this embodiment may further include: before the de-duplication processing of the data to be synchronized according to the backup data, after the data is obtained according to the data synchronization instruction, the method in this embodiment may further include:

The synchronized data is divided according to a preset rule to obtain a plurality of sub-data.

The step of performing deduplication processing on the data to be synchronized according to the backup data to obtain the target data to be synchronized may specifically include:

The duplicate sub-data in the data to be synchronized is deleted to obtain the deleted target to be synchronized data.

Wherein, in the step of determining whether the subdata has the same data sample in the backup data. The foregoing sub-data may be a sub-data or a batch of sub-data, that is to say, the judging method in the embodiment of the present invention may judge a plurality of sub-data one by one, or may simultaneously judge a plurality of sub-data (ie, Batch processing).

Specifically, determining whether the subdata is the same as the backup data may be implemented by using a hash value. The hash value is a value obtained by logical operation based on the data of the contents of the file. Different files (even the same file name) get different hash values. So the hash value becomes the ID of each file. Specifically, the hash value of the sub data may be obtained, and compared with the hash value of the backup data to check whether there is an identical item. If yes, it is determined that the same item is a duplicate sub-data and is deleted, so as to be deleted. The target is to be synchronized data.

In other embodiments, the duplicate sub-data may also be determined by the history record corresponding to the backup data. The historical record may include feature information of the backup data that has been backed up, and then extract feature information of the sub data, and compare with the feature information of the backup data, and determine the sub data having the same feature information as the backup data as The sub-data is repeated, and the sub-data different from the feature information of the backup data is the target to-be-synchronized data.

Preferably, after determining the target to be synchronized data, the server may further back up the target to be synchronized data. For example, if the backup data includes 10 sub-data, first determine whether the 10 sub-data has been backed up. If 6 sub-data has been backed up, that is, repeat the sub-data, the remaining 4 sub-data are determined as the target to-be-synchronized data. And backup these 4 sub-data to the storage medium of the server.

Step S104: Send the target to-be-synchronized data to the login terminal that logs in to the cloud account, so that the login terminal completes the data synchronization.

In the embodiment of the present invention, the login terminal and the terminal are terminals that log in to the same cloud account, and the login terminal may be one or more. In this embodiment, the data synchronization can be completed based on the cloud account. For example, in the case that a backup account corresponds to multiple terminals, after the server obtains the target to be synchronized data, the target to be synchronized data can be sent to all the login logs. On the terminal of the account.

Considering that the terminal is the initiator of the data synchronization instruction, the terminal does not need to receive the target to be synchronized data, so all terminals that log in to the cloud account can be obtained, and the terminal other than the terminal is determined to be the login terminal.

Preferably, in the embodiment of the present invention, the login terminal can be determined by the terminal identifier. Specifically, the method in this embodiment may further include: performing de-duplication processing on the data to be synchronized according to the backup data to obtain the target to-be-synchronized data, and before sending the target to-be-synchronized data to the login terminal that is logged in to the cloud account, the method in this embodiment may further include:

Determining whether there is a same sample identifier as the terminal identifier in the preset identifier set;

If yes, it is determined that the terminal corresponding to the terminal identifier is the login terminal.

The terminal identifier may be a unique identifier of the terminal, and specifically, may be an identifier of the terminal in the communication network terminal. There may be multiple types of terminal identifiers. For example, the terminal identifier may be IMEI (International Mobile Equipment Identity, International Mobile Device Identity), MAC Address (Media Access) Control, physical address), or the number used by the terminal (such as mobile phone number).

Optionally, in the process of sending the target to be synchronized data to the login terminal, if the server is interrupted due to a network failure or a server failure of the login terminal, the server may pause the data transmission and record the data interruption node. The information, when the above fault is recovered, can continue to transmit the target to be synchronized data according to the node information, thereby ensuring data integrity.

It can be seen that the data synchronization method provided by the embodiment of the present invention can receive a data synchronization instruction sent by the terminal, where the data synchronization instruction carries a cloud account and data to be synchronized, acquires backup data according to the data synchronization instruction, and performs synchronization data according to the backup data. De-reprocessing to obtain the target to-be-synchronized data, and sending the target to-be-synchronized data to the login terminal that logs in to the cloud account, so that the login terminal completes the data synchronization. The solution can realize data synchronization between the terminal and the terminal, and can de-reprocess the data that needs to be synchronized, and reduce the amount of data that needs to be synchronized, thereby speeding up data transmission, effectively improving the efficiency of data synchronization, thereby saving users. Time, with a better user experience.

First, when a user simultaneously uses a plurality of terminals, the user data in one of the terminals can be synchronized to other terminals through the server after being modified. For example, a contact information is added to the terminal. However, when data synchronization is performed, the server often receives all the contact information in the terminal and synchronizes it to other terminals, which occupies more resources of the server. Big will also make data synchronization slower. Therefore, the present invention provides a data synchronization method, which can perform deduplication processing on synchronous data, and send the processed target to be synchronized data to other terminals for synchronization, thereby greatly improving synchronization efficiency.

In a preferred embodiment, please refer to FIG. 3, a data synchronization method, and the specific process is as follows:

Step S201: Receive a data synchronization instruction sent by the terminal.

The data synchronization instruction carries a cloud account and data to be synchronized that needs to be synchronized. The above-mentioned data to be synchronized may include an address book, a memo, a short message, a chat record, a picture information, a multimedia information, an application usage record, and the like.

For example, when a user adds a contact information to the terminal, a prompt box may pop up to prompt the user to synchronize the contact information to other terminals. The user may click the “OK” button on the terminal screen, and the terminal is based on the terminal. The above new contact information generates a data synchronization instruction and sends it to the server.

Step S202, acquiring backup data according to the data synchronization instruction.

In this embodiment, the backup data is the data that is last backed up by the terminal on the cloud server, where the terminal may be any terminal that logs in to the cloud account.

Step S203, dividing the data to be synchronized according to a preset rule to obtain a plurality of sub-data.

For example, the classified data may be classified according to the data type, and the data to be classified may be divided into address book sub data, picture sub data, music sub data, short message sub data, and the like. It can also be divided according to the data size or other characteristic values, and is not further limited herein.

Step S204, acquiring the same repeated sub-data of the plurality of sub-data as the backup data.

The embodiment of the present invention may be implemented by using a hash value, for example, a hash value of the sub data may be obtained, and compared with the hash value of the backup data to check whether there is an identical item, and if yes, determining that the same item is a duplicate Subdata.

In other embodiments, the duplicate sub-data may also be determined by the history corresponding to the backup data. The historical record may include the feature information of the backup data that has been backed up, and then extract the feature information of the sub-data, and compare with the feature information of the backup data to determine the sub-data having the same feature information as the backup data. To repeat the subdata.

Step S205, deleting the repeated sub-data in the data to be synchronized to obtain the target to-be-synchronized data after the deletion.

For example, if the backup data includes 10 sub-data, firstly, it is determined whether the 10 sub-data has been backed up. If 6 sub-data has been backed up, that is, the sub-data is repeated, the remaining 4 sub-data are determined as the target to-be-synchronized data.

Step S206: Acquire a terminal identifier corresponding to the terminal that logs in to the cloud account.

In step S207, it is determined whether there is a sample identifier that is the same as the terminal identifier in the preset identifier set. If yes, step S208 is performed, and if not, the process ends.

Step S208, determining that the terminal corresponding to the terminal identifier is a login terminal.

For example, a whitelist may be set in advance, and after obtaining the terminal identifier corresponding to the terminal that is logged in to the cloud account, it is determined whether the terminal identifier is in the whitelist, and if so, the terminal corresponding to the terminal identifier is determined to be the login terminal, That is, the terminal that needs to synchronize data.

Optionally, in another embodiment, a blacklist may be set, and then the terminal identifier corresponding to the terminal that logs in to the cloud account is determined to be in the blacklist. If not, the terminal corresponding to the terminal identifier is determined to be the login terminal.

Step S209, the target to-be-synchronized data is sent to the login terminal, so that the login terminal completes the data synchronization.

It can be seen that the data synchronization method provided by the embodiment of the present invention can receive the data synchronization instruction sent by the terminal, acquire the backup data according to the data synchronization instruction, divide the synchronization data according to the preset rule, and obtain multiple sub-data to obtain multiple sub-data. The duplicate sub-data in the same manner as the backup data is deleted, and the duplicate sub-data in the data to be synchronized is deleted, so that the deleted target data to be synchronized is obtained, and the terminal identifier corresponding to the terminal that logs in to the cloud account is obtained, and the preset identifier set is determined. Whether there is a sample identifier that is the same as the terminal identifier. If yes, the terminal corresponding to the terminal identifier is determined to be a login terminal, and the target to-be-synchronized data is sent to the login terminal, so that the login terminal completes data synchronization. The solution can realize data synchronization between the terminal and the terminal, and can de-reprocess the data that needs to be synchronized, and reduce the amount of data that needs to be synchronized, thereby speeding up data transmission, effectively improving the efficiency of data synchronization, thereby saving users. Time, with a better user experience.
