Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those skilled in the art's every other implementation obtained without creative efforts Example, shall fall within the protection scope of the present invention.

The embodiment of the present invention provides a kind of multiple terminals method of data synchronization based on cloud storage, device and system.Divide below It is not described in detail.

Embodiment one,

The embodiment of the present invention will be described from the angle of cloud device, which is specifically as follows the nets such as server Network side apparatus.

A kind of multiple terminals method of data synchronization based on cloud storage, comprising: receive terminal and sent in real time by binding account End-user listening data synchronized update message, according to the corresponding total buffer zone of the synchronized update information updating binding account In corresponding with terminal Backup Data caching, updated total buffer zone is obtained, according to buffer zone pair total after the update The end-user listening data in all terminals under the binding account synchronizes, and refers to if getting backtracking in preset time Show, then indicates buffer zone total after update backtracking to be total buffer zone before update according to the backtracking；If in preset time Backtracking instruction has not been obtained, then regard the Backup Data caching in buffer zone total after the update as Backup Data.

As shown in Figure 1, being somebody's turn to do the detailed process of the multiple terminals method of data synchronization based on cloud storage can be such that

101, the synchronized update message for the end-user listening data that terminal is sent in real time by binding account is received.

Wherein, binding account can be phone number, QQ number code, Email Accounts or other can identify the account of user identity Number etc..Wherein, a binding account can be used for multiple terminals, i.e., one binding account can correspond to multiple terminals, and Since this multiple terminal all has corresponding buffer zone beyond the clouds, it can collect this multiple buffer zone as one It closes, referred to as total buffer zone, total buffer zone is corresponding with binding account, i.e., each binding account is corresponding with a total caching Region.For example, by taking the binding account of terminal A, terminal B and terminal C are account 1 as an example, if terminal A is corresponding slow beyond the clouds Depositing region is buffer zone 1, and corresponding buffer zone is buffer zone 2, terminal C corresponding caching beyond the clouds to terminal B beyond the clouds Region is buffer zone 3, then total buffer zone corresponding to account 1 may include buffer zone 1, buffer zone 2 and buffer area Domain 3.

In addition, before receiving synchronized update message of the terminal by binding the end-user listening data that account is sent in real time, The end-user listening data that multiple terminals are uploaded respectively by same binding account can also be received, then according to terminal user's number Corresponding Backup Data caching is generated according to terminal respectively each in the corresponding total buffer zone of the binding account.

Then at this point, step " receives the synchronized update message for the end-user listening data that terminal is sent in real time by binding account (step 101) " is specifically as follows: receiving any terminal in multiple terminal and passes through the terminal user that the binding account is sent in real time The synchronized update message of data.

102, according to corresponding with the terminal in the corresponding total buffer zone of the synchronized update information updating binding account Backup Data caching, obtains updated total buffer zone.

It should be noted that due to cloud synchronize be more buffer zones set, when some buffer zone therein send out When changing, total buffer zone can also change, so, a new total buffer zone is generated at this point, can synchronize, in this hair In bright embodiment, referred to as updated total buffer zone.Wherein, total buffer zone carry timestamp to confirm that update when Between.

103, according to buffer zone total after the update to the end-user listening data in all terminals under the binding account into Row synchronizes.

For example, if the terminals such as terminal A, terminal B and terminal C all correspond to the binding account, at this point it is possible to according to this Total buffer zone synchronizes the end-user listening data of the terminals such as terminal A, terminal B and terminal C after update.

Be simultaneously indicated for example, can specifically be sent to terminals such as terminal A, terminal B and terminal C, so as to terminal A, terminal B and Terminal C determines whether to receive synchronization according to the synchronizing indication, if not receiving synchronization, can raise an objection or request again more The end-user listening data etc. in new cloud.

104, determine backtracking instruction whether is got in preset time, if so, 105 are thened follow the steps, if it is not, then executing step Rapid 106.

If 105, getting backtracking instruction in preset time, total buffer zone is returned after being updated according to backtracking instruction It traces back as total buffer zone before update.

If getting backtracking instruction in preset time, show that update operation may be maloperation, therefore, it is necessary to It is total buffer zone before update by buffer zone total after update backtracking, that is, restores data, to guarantee the correctness of data.Its In, backtracking instruction can generate in following situation:

If updated total buffer zone is updated again in preset time, backtracking instruction is generated；Alternatively,

If receiving any terminal under the binding account in preset time to raise an objection, backtracking instruction, etc. is generated.

Wherein, which can be configured according to the demand of practical application, for example, can be set waiting 5 minutes, 10 minutes or 20 minutes, etc., details are not described herein.

If backtracking instruction 106, has not been obtained in preset time, by the Backup Data in buffer zone total after the update Caching is used as Backup Data.

If backtracking instruction has not been obtained in preset time, show update operation effectively, it therefore, can be by this more Backup Data caching after new in total buffer zone is used as Backup Data.

From the foregoing, it will be observed that the present embodiment is using the synchronization for receiving the end-user listening data that terminal is sent in real time by binding account Update message, according to backup corresponding with the terminal in the corresponding total buffer zone of the synchronized update information updating binding account Data buffer storage obtains updated total buffer zone, then according to buffer zone total after the update to the institute changed under binding account There is the end-user listening data in terminal to synchronize, hereafter, if getting backtracking instruction in preset time, is referred to according to backtracking Show otherwise buffer zone total after update backtracking is then confirmed into update effectively for total buffer zone before updating, it will be total after the update Backup Data caching in buffer zone is used as Backup Data.The use of real-time automatic synchronization multiple terminals not only may be implemented in the program User data, moreover, because whether the update of data can effectively be detected in preset time after synchronization, it therefore, can To avoid the update of data caused by maloperation, for example the generation for the case where increasing end-user listening data is accidentally deleted or missed, greatly improves Data synchronous flexibilities and safety.

Embodiment two,

The present embodiment will be described from the angle of terminal, which is specifically as follows mobile phone, tablet computer or personal meter The equipment such as calculation machine (PC, Personal Computer).

A kind of multiple terminals method of data synchronization based on cloud storage, comprising: receive cloud device and always cached according to after update The synchronizing indication that region is sent determines whether current sync operation is correct according to the synchronizing indication, if correctly, to terminal user Data synchronize；If incorrect, in preset time touching make cloud device generate backtracking instruction, so as to cloud device according to Buffer zone total after update backtracking is total buffer zone before update by backtracking instruction.

As shown in Fig. 2, being somebody's turn to do the multiple terminals method of data synchronization based on cloud storage, detailed process be can be such that

201, the synchronizing indication that cloud device is sent according to buffer zone total after update is received, wherein the synchronizing indication It generates for details, reference can be made to embodiment one, details are not described herein.

Optionally, other than it can receive the simultaneously operating in cloud, which can also update cloud with activly request and protect The end-user listening data deposited, i.e., step " synchronizing indication that total buffer zone is sent after receiving cloud device according to update " it Before, being somebody's turn to do the multiple terminals method of data synchronization based on cloud storage can also include:

The synchronized update message of end-user listening data is sent, in real time to cloud device by binding account so as to cloud device Corresponding Backup Data caching, obtains more in the corresponding total buffer zone of binding account according to the synchronized update information updating Total buffer zone after new.

Wherein, binding account can be phone number, QQ number code, Email Accounts or other can identify the account of user identity Number etc..Wherein, a binding account can be used for multiple terminals, i.e., one binding account can correspond to multiple terminals, and Since this multiple terminal all has corresponding buffer zone beyond the clouds, it can collect this multiple buffer zone as one It closes, referred to as total buffer zone, total buffer zone is corresponding with binding account, i.e., each binding account is corresponding with a total caching Region.

In addition, before the synchronized update message for sending end-user listening data in real time to cloud device by binding account, End-user listening data can also be uploaded to cloud device by binding account, so that cloud device exists according to the end-user listening data Corresponding Backup Data caching is generated in the corresponding total buffer zone of the binding account.

202, determine whether current sync operation is correct according to the synchronizing indication, if correctly, thening follow the steps 203, if not Correctly, 204 are thened follow the steps.

203, if it is determined that current sync operation is correct, then end-user listening data is synchronized.

204, if it is determined that current sync operation is incorrect, then touching makes cloud device generate backtracking instruction in preset time, So that cloud device indicates buffer zone total after update backtracking to be total buffer zone before update according to the backtracking.

For example, the synchronized update message of end-user listening data can be specifically sent to cloud device in preset time, with Buffer zone total after the update is updated, so that cloud device is generated backtracking instruction with touching；Alternatively,

It raises an objection in preset time to cloud device, so that cloud device is generated backtracking instruction, etc. with touching.

From the foregoing, it will be observed that the present embodiment is the corresponding method of embodiment one, in the present embodiment, terminal can receive cloud and set Then the standby synchronizing indication sent in real time according to buffer zone total after update determines that current sync operation is according to the synchronizing indication No correct, if correctly, synchronizing to end-user listening data, if incorrect, touching keeps cloud device raw in preset time It is indicated at backtracking, so that cloud device indicates to be total slow before updating by buffer zone total after update backtracking according to the backtracking Deposit region；The user data of real-time automatic synchronization multiple terminals not only may be implemented in the program, moreover, because can after synchronization In preset time, whether the update of data is effectively detected, it can thus be avoided data caused by maloperation update, Such as the generation for the case where accidentally deleting or accidentally increasing end-user listening data, substantially increase data synchronous flexibility and safety.

Embodiment three,

According to method described in embodiment one and two, citing is described in further detail below.

In the present embodiment, it will be illustrated for the synchronization between terminal A, terminal B and terminal C, wherein terminal A, Terminal B and terminal C needs to bind the same cloud account (i.e. binding account).Wherein, the binding account can be phone number, QQ number code, Email Accounts or other can identify account of user identity etc..

A kind of multiple terminals method of data synchronization based on cloud storage, as shown in Figure 3a, detailed process can be such that

301, the respective end-user listening data that terminal A, terminal B and terminal C are uploaded by the same binding account respectively.

Wherein, the binding account can be phone number, QQ number code, Email Accounts or other can identify user identity Account etc..

302, cloud device is after receiving the end-user listening data that terminal A, terminal B and terminal C are uploaded respectively, according to The end-user listening data received is respectively that each terminal generation is corresponding standby in the corresponding total buffer zone of the binding account Part data buffer storage.

For example, by taking the binding account is specially cell-phone number " 12345678900 " as an example, then as shown in Figure 3b, beyond the clouds, hand Machine number " 12345678900 " can correspond to total buffer zone M, and terminal A can specifically correspond to the buffer zone 1 in total buffer zone M, Terminal B can specifically correspond to the buffer zone 2 in total buffer zone M, and terminal C can specifically correspond to the buffer area in total buffer zone M Domain 3.

303, when the end-user listening data in terminal A changes, terminal A is set to cloud in real time by the binding account Preparation send synchronized update message.

304, cloud device according in the corresponding total buffer zone of the synchronized update information updating binding account with terminal A Corresponding Backup Data caching, for example buffer zone 1 is updated to buffer zone 1 ', obtain updated total buffer zone.Its In, which can carry timestamp to confirm that the time updated.

For example, as shown in Figure 3c, specifically the corresponding buffer zone 1 terminal A can be updated to buffer zone 1 ', and submit To total buffer zone M, to refresh total buffer zone M, so that total buffer zone M is updated to total buffer zone N.

305, cloud device uses the terminal in all terminals under the binding account according to buffer zone total after the update User data synchronizes, and in the present embodiment, i.e., synchronizes to the end-user listening data in terminal A, terminal B and terminal C.

It is simultaneously indicated for example, can specifically be sent to terminals such as terminal A, terminal B and terminal C.

306, terminal A, terminal B and terminal C are after the synchronizing indication for receiving cloud device transmission, respectively according to the synchronization Indicate determine whether the simultaneously operating is correct, if correctly, synchronizing to end-user listening data, if incorrect, preset Touching makes cloud device generate backtracking instruction in time.

For example, by taking terminal A determines that the simultaneously operating is incorrect as an example, then terminal A can be touched in preset time and be made at this time Cloud device generates backtracking instruction, for example, specifically the same of end-user listening data can be sent to cloud device in preset time Update message is walked, to be updated to buffer zone total after the update, so that cloud device is generated backtracking instruction with touching；Alternatively, It raises an objection in preset time to cloud device, so that cloud device is generated backtracking instruction, etc. with touching.

It is of course also possible to which being touched in preset time by terminal B and/or terminal C makes cloud device generate backtracking instruction, in fact Existing identical, details are not described herein.

Wherein, which can be configured according to the demand of practical application, for example, can be set to 10 minutes or 15 minutes, etc..

307, cloud device starting timing detects, to confirm whether get backtracking instruction in preset time, if obtained Backtracking instruction is got, thens follow the steps 308, otherwise, if backtracking instruction has not been obtained, thens follow the steps 309.

For example, specifically can be confirmed whether updated total buffer zone is updated again in preset time, or The no objection, etc. for receiving any terminal under the binding account and proposing, if updated total caching in preset time Region is updated or receives again the objection that any terminal proposes under the binding account, then shows that the update may be maloperation It is caused, it is therefore contemplated that the update is invalid (determining that total buffer zone N is invalid), backtracking instruction is then generated, and execute step 308, otherwise, if updated total buffer zone is not updated in preset time, and also it is not received by the binding The objection that any terminal proposes under account, then it is assumed that the update effectively (determining that total buffer zone N is effective), therefore, can be held Row step 309.

If 308, getting backtracking instruction in preset time, total buffer zone is returned after being updated according to backtracking instruction It traces back as total buffer zone before update.

For example, as shown in Figure 3c, total buffer zone N recall for total buffer zone M, i.e., by the recovery of buffer zone 1 caching Region 1 '.

If backtracking instruction 309, has not been obtained in preset time, by the Backup Data in buffer zone total after the update Caching is used as Backup Data.

For example, as shown in Figure 3c, it specifically can be using the file in total buffer zone N as new Backup Data.
