Wherein, the second equipment can be the terminals such as mobile phone, panel computer, desktop computer, and application is provided with the second equipment, The application can be social networking application, multimedia application etc., and applying can produce various data during use.First equipment can Think the terminals such as mobile phone, panel computer, desktop computer, the first equipment can also be server.When the first equipment is terminal, the Identical application can also be installed with the second equipment in one equipment, or the first equipment is provided with application backup functionality Using.Wherein, the operating system of the first equipment and the second equipment can be the same or different, and the embodiment of the present invention is not made to this Limit.

The data backup of the present embodiment is used to back up the data applied in the second equipment, for the ease of description, will The application referred to as intended application of backup is needed in second equipment.Introduction based on above-mentioned first equipment and the second equipment, this reality Apply needed for example back up data flow can be from terminal-to-terminal service, or be from terminal to server, detailed data backup The specific embodiment that flow is provided referring to following Fig. 2A.

Fig. 2A is a kind of flow chart of data back up method provided in an embodiment of the present invention, and referring to Fig. 2A, interaction agent is related to And first equipment and the second equipment, the method flow includes：

201st, the second equipment obtains the facility information of the first equipment, is set up with the first equipment according to the facility information and is connected.

In the present embodiment, when the first equipment and the second equipment are terminal, the first equipment and the second equipment may be at In same LAN, the two can be by wired or wirelessly foundation connection.Wherein, wired connection mode includes USB is connected, netting twine is direct-connected etc..Radio connection includes WiFi (Wireless Fidelity, Wireless Fidelity) connections, bluetooth Connection etc..The step 201 can be skipped when the first equipment is server and directly performs step 202.

Wherein, the first equipment same with the second equipment can be provided with intended application, it is also possible to be not installed with intended application. User can be by the first equipment trigger data backup flow, such as, when the first equipment is provided with intended application, can be in mesh The data backup option for realizing data backup is provided with the function interface for marking application so that user can be somebody's turn to do by clicking on Data backup option carrys out trigger data backup flow.In addition, when intended application is not installed with, the first equipment can be installed promising Intended application provides the specified application of backup services, and the data of intended application backup are provided with the function interface of the specified application Backup options so that user can be by clicking on the data backup option come trigger data backup flow.

Certainly, user can also be by the second equipment trigger data backup flow, such as, when the second equipment is detected to mesh During the trigger action of the data backup option for marking application, the session list of display target application, user can be in the session list Middle selection needs the target session of backup；When the selection that the second equipment detects target session confirms operation, trigger data is standby Part flow.Such as, user can choose session 1 and session 2 as target session etc. in session list.Additionally, the second equipment Backup can also automatically be triggered according to predetermined period, the predetermined period can be pre-set or more by server or the second equipment Change, the present embodiment is not construed as limiting to this.After backup flow is triggered, the first equipment detects whether to be had built up with the second equipment Connection, if not setting up connection, performs the process set up with the second equipment and be connected.If having set up connection, set to second Preparation send backup instruction, after receiving backup instruction by the second equipment, performs step 202.

Below so that user passes through the first equipment trigger data backup flow as an example, the second equipment and the first equipment are set up and is connected The process for connecing is introduced：

After trigger data backup flow, the second equipment needs to be set up with the first equipment and is connected, standby so as to carry out data Part.For example, the second equipment can be set up by the facility information of the first equipment for obtaining with the first equipment connecting.Wherein, The facility information of one equipment includes the IP address of the first equipment and provides the port numbers of data backup service.Second equipment obtains the The mode of the facility information of one equipment can include any one in following three kinds：

First way, the second equipment obtain the facility information of the first equipment by server.

In this kind of mode, the first equipment is same with the second equipment to be provided with intended application, and is logged in identical account.When When first equipment detects the trigger action of the data backup option, send backup flow to server and initiate message, the backup Flow initiates message and carries the facility information of the first equipment and log in the first account of intended application.Server is according to the first account Number, sending backup flow to the second equipment for being logged in identical account and initiate to indicate, the backup flow initiates to carry in instruction the The facility information of one equipment, so that the second equipment gets the facility information of the first equipment.Certainly, the backup flow is initiated Indicate can also be without carry the first equipment facility information, but by the second equipment receive the backup flow initiate indicate after from The facility information of server pull first equipment, the embodiment of the present invention is not construed as limiting to this.

The second way, the second equipment are believed by the equipment that the facility information broadcast message of the first equipment obtains the first equipment Breath.

In this kind of mode, the first equipment can be provided with intended application, it is also possible to be not installed with intended application.Set when first During for detecting the trigger action to the data backup option of intended application, the facility information of itself is broadcasted in LAN, when When second equipment is in same LAN with the first equipment, just can be broadcast the message by LAN Access to the facility information, So as to extract the facility information of the first equipment from facility information broadcast message.

The third mode, the second equipment obtain the facility information of the first equipment by two-dimensional code scanning.

In this kind of mode, the first equipment can be provided with intended application, it is also possible to be not installed with intended application.Set when first During for detecting the trigger action to the data backup option of intended application, according to the facility information of itself, Quick Response Code is generated.The Two equipment obtain the facility information of the first equipment by scanning the Quick Response Code.

For the above-mentioned second way and the third mode, when intended application is provided with the first equipment, the data are standby The flow of part is considered as being the process of intended application data syn-chronization.In order to ensure the security of data backup, it is to avoid by one To another account, the second equipment can also obtain the first account that the first equipment logs in intended application to the data syn-chronization of account. Such as, for above-mentioned second situation, the first equipment can also be broadcasted the first account so that the second equipment gets this First account.For above-mentioned the third situation, first account, the second equipment can be included in the Quick Response Code of the first equipment generation The first account is got by scanning Quick Response Code.After second equipment gets the first account, with local log-on intended application Two accounts are contrasted, if the two is identical, is set up with the first equipment and are connected；If it is not the same, then refusing and the first equipment Connection is set up, meanwhile, the second equipment can show account difference prompt message, to point out user data backup to there may be wind Danger.

After second equipment gets the facility information of the first equipment, can be by wired or wirelessly set with first Standby foundation in same LAN is directly connected to, and the process of foundation connection can be：Second equipment is according to the first equipment IP address, to the first equipment sending data connection request.If the first equipment receives the data connection request, can be to second Equipment returns to a response message.If the second equipment receives the response message of the first equipment, illustrate the two in same In individual LAN, connection can be directly set up, then the second equipment is set up with the first equipment and is connected.If the second equipment is not received To the response message of the first equipment, it is determined that be not in same LAN with the first equipment, it is impossible to which foundation is directly connected to.This When, in order to guarantee successfully as user carries out data backup, the second equipment display network connection prompt message, the network connection Prompt message is used to indicate the second equipment to be in different LANs from the first equipment, such as the network connection prompt message can Think information such as " two equipment are please connected to same LAN ".

Certainly, even if the first equipment and the second equipment are in same LAN sometimes, it is also possible to because network The reasons such as failure (such as netting twine is not plugged, or router failure etc.) so that the first equipment does not receive the number of the second equipment According to connection request, or cause that the second equipment does not receive the response message that the first equipment has been returned.Therefore, in order to anti-to user Reflect real connection, to improve the success rate of connection, the second equipment when response message is not received, can also carry out with Lower step：According to the IP address and local ip address of the first equipment, judge whether be in same LAN with the second equipment.Than Such as, whether the IP address of the first equipment of the second equipment detection and the network number of local ip address are identical, if identical, it is determined that with First equipment is in same LAN.At this point it is possible to point out user to check that a lower network is the presence of failure, such as, check network Whether connection is normal etc..Wherein, network number is used for the LAN ID of instruction equipment IP address.

Further, since different WLANs generally has different SSID (Service Set Identifier, clothes Business set identifier), when the first equipment or the second equipment pass through WiFi access networks, the facility information of the first equipment can also include The SSID of WLAN residing for first equipment, the second equipment can be by contrasting the SSID and local SSID of the first equipment come really It is fixed whether to be in same LAN with the first equipment.Such as, when the SSID of the two is different, it is determined that the two is not at same local In net, now the second equipment shows network connection prompt message, and now the network connection prompt message can serve to indicate that and will set It is standby to be connected to same WiFi, such as, the information such as " two equipment are please connected to same WiFi ", such prompting can be with Some are made not understand the user of LAN concept, it is also possible to by pointing out to be connected to two equipment in same LAN, The universality of the data back up method is improve, operability is enhanced.

It should be noted that for the second way of the facility information of above-mentioned acquisition first, due to the equipment of the first equipment Information by LAN broadcast, therefore, when the second equipment receives the facility information of the first equipment, just can determine that with First equipment is in same LAN, now can directly be set up with the first equipment according to the facility information for getting and is connected.

Connection is set up in same LAN by by the first equipment and the second equipment, data backup procedure is substantially increased In data transmission bauds, the efficiency of data backup is improve, simultaneously as LAN is not readily susceptible to external interference, network Good stability, this improves the reliability of data transfer, it is to avoid the problem for causing backup efficiency to decline due to packet loss.

Fig. 2 B show a kind of flow chart of data backup based on above-mentioned first way, in fig. 2b when the first equipment is examined When measuring the trigger action of data backup option, send backup flow to server and initiate message, the backup flow initiates message The facility information for carrying the first equipment and the first account for logging in intended application.Can be to other flows of Fig. 2 B in subsequent step It is introduced.

In order to ensure the security of data transfer, the data of interaction are encryption data between the first equipment and the second equipment, Specifically, after detecting data backup flow and being triggered, the first equipment detects whether local cipher key cache area is stored with Key, if the local key that is not stored with, the first equipment can obtain the key from server.Second equipment can also be from clothes Business device obtains identical key, and the first equipment and the second equipment can be added using the key to the data sent to opposite end It is close, and when the data of opposite end are received, can be decrypted using the key.

The security of connection is set up to be further ensured that, the first equipment and the second equipment can also interact password to carry out Password authentication, the process of the password authentication can be：Second equipment sends password authentication message (Packet to the first equipment Authenticate Request), the first password (such as hello passwords) to be verified is carried in the password authentication message；The After one equipment receives the first password, if detect that first password has been locally stored, the password to the second equipment is confirmed It is proved to be successful, password authentication success message (Packet Authenticate Response) is sent to the second equipment, and at this The second password (such as ok passwords) to be verified is carried in password authentication success message, the first equipment receives second password Afterwards, second password has been locally stored if detected, has confirmed the password authentication success to the first equipment, and to the first equipment Return to password and be proved to be successful message, the password authentication success message also can be by Packet Authenticate Request message Carry.In addition, after the first equipment receives the password authentication success message of the second equipment, password authentication can be returned and confirm to disappear Breath, to show that verification process terminates, the confirmation message can also be by Packet Authenticate Response message bearings. Wherein, the first password and the second password can be respectively configured to the second equipment and the first equipment by server.

It should be noted that the present embodiment provide the first equipment (or second equipment) except provide data backup function it Outward, when Transmission can also occur in data backup procedure, data backup is proceeded based on the progress backed up when interrupting； It may, furthermore, provide data recovery function, and when there is Transmission in data recovery procedure, based on recovery when interrupting Progress proceed data recovery.During specific implementation, corresponding function can be provided in the first equipment (or second equipment) Option, or corresponding function choosing-item is provided on the function interface of intended application, enable a user to triggering corresponding Flow.When user triggers certain flow by the first equipment, in order which flow that the second equipment is clearly currently triggered, the After one equipment and the second equipment set up connection, (Backup Command are indicated to the second equipment transmission flow type Request), the flow type is indicated for indicating data backup, continuing backup, data recovery, the one kind continued in recovery.The Two equipment are received to be returned after the flow type is indicated and confirm response message (Backup Command Response).Subsequently, Two equipment can also be indicated when ready to the first equipment transmitter ready, and the ready instruction can also be by Backup Command Request message bearings, return confirms that response disappears after receiving the ready instruction by the first equipment Breath (Backup Command Response).

202nd, to the first equipment sending data backup request, data backup requests are used to indicate mesh to be backed up the second equipment Rotating savings is talked about.

Based on the connection that step 201 is set up, the second equipment can carry out data transmission with the first equipment, it is necessary to illustrate It is that the data transfer in the step and subsequent step is all based on the connection, and explanation is no longer repeated this in subsequent step.

After it is determined that being successfully established with the first equipment and being connected, the second equipment enters data backup flow, such as, second sets It is standby the session list of intended application, the session column to be included with display target session selection interface, the target session selection interface Table includes multiple session options, and each session option includes session identification, head portrait and the choice box of session, and user can pass through Choice box is clicked on to choose the target session for needing to back up.Wherein, the session due to there is no need to be recorded as message zero is carried out Backup, therefore in order to improve the accuracy of data backup, session list can only include shown in target session selection interface The session that Message Record is not zero, further, corresponds to each session, can also show the session comprising the big of Message Record It is small, such as 5M etc..Additionally, in order to ensure that backup flow is carried out in order, the second equipment can also send data backup requests it Before, send backup to the first equipment and start message (Backup Start Request), disappear returning to confirmation by the first equipment After breath (Backup Start Response), data backup requests are retransmited, the data backup requests can be by Backup Request Session message bearings.

Wherein, the number of target session can be one or more, and the present embodiment is not construed as limiting to this.When the inspection of the second equipment Measure when confirming operation to the selection of target session, to the first equipment sending data backup request, the data backup requests can be with Session identification including target session.Wherein, for one-to-one session, session identification can be the pet name, the account of session opposite end Deng for cluster conversation, session identification can be group name etc..

In embodiments of the present invention, the Message Record of session refer to interacted between session local terminal and session opposite end word, The data such as picture, voice and video.Every Message Record includes that the type of the generation time Message Record of the Message Record includes Word message is recorded and media information record.Wherein, media information record is including picture, voice and video etc..Wherein, media disappear Breath record includes respective media message in itself and its description information, and the description information is used to describe the message mark of respective media message Knowledge, medium type, generation time, media information record size etc..

203rd, when the first equipment receives the data backup requests of the second equipment, obtain backup corresponding with target session and cut Only time.

First equipment be stored with backup messages record backup by the corresponding relation between time and session identification.First The corresponding relation that equipment can have been stored according to the inquiry of the session identification of target session, when the backup for obtaining target session ends Between.For example, the corresponding relation can be as shown in table 1.

Table 1

Certainly, the storage address of session identification respective session can also be stored in the corresponding relation so that the first equipment can Directly to determine the storage region of certain session by the corresponding relation.

204th, the first equipment sends to the second equipment the backup deadline of target session.

If target session includes multiple sessions, the first equipment correspondence each session return backup corresponding with the session Deadline, the present embodiment is only introduced so that target session includes a session as an example.

It should be noted that the backup deadline of above-mentioned target session can respond (Backup by data backup Request Session Response) carry, the embodiment of the present invention is not limited its specific bearing mode.

205th, the second equipment determines that target message is recorded according to the backup deadline of target session, target message record For the Message Record that target session is produced after deadline is backed up.

In the present embodiment, the order arrangement of Message Record included by session according to generation time from after arriving first.Second sets The standby backup deadline according to target session, the message note produced after the backup deadline is extracted from target session Record.Specifically, the second equipment can be according to order of the generation time from after arriving first, by target session during the generation of Message Record Between compare with the backup deadline, until get generation time be later than backup deadline first message note Record, just the Message Record by first message record and its afterwards is defined as target message record.Certainly, the second equipment can also According to generation time from rear to first order, the generation time of Message Record in target session is carried out with the backup deadline Compare, until getting second Message Record of the generation time equal or earlier than the backup deadline, just this second disappears Message Record after breath record is defined as target message record.

If it should be noted that the second equipment determines that target session does not produce new disappearing after the backup deadline Breath record, it is determined that the target session does not have data to need backup, now, the second equipment can send to the first equipment and back up Into message, to terminate the backup flow.If the number of target session is multiple, the second equipment determines that each target session is equal New Message Record is not produced after respective backup deadline, backup completion message is sent to the first equipment, to terminate to be somebody's turn to do Backup flow.Wherein, backup completion message can be by Backup Finish Request message bearings.If the second equipment is obtained The target message record of target session is got, then sending target message to the first equipment records, and the process comprises the steps 206 To 208.

206th, order of second equipment according to the generation time of Message Record from after arriving first, the target message is recorded and is divided It is at least one massage set.

In the present embodiment, in order to the more fine-grained Message Record to intended application is processed, answered rather than by target Message Record regards an entirety as, with the breakpoint transmission in the incremental backup and backup procedure of realizing Message Record, During data backup, Message Record to be backed up can be divided into one or more massage sets by the second equipment.

Wherein, for the different type of Message Record, massage set can include word message set and media information collection Close.Wherein, word message set includes the description information of word message record and media information record, each description information For indicating corresponding media information to record.Media information set includes that media information is recorded.

Specifically, order of second equipment according to generation time from after arriving first, by word Message Record in target message and The description information of media information record is combined into word message set, and media information record is combined into media information set.Example Such as, order of second equipment according to generation time from after arriving first obtains every Message Record in target message record, if should Message Record is recorded for word message, then the word Message Record is added into word message set, if the Message Record is Media information is recorded, then the description information that the media information is recorded is added into word message set, by media information record It is added to media information set.

Wherein, for more fine-grained division massage set, can also be on the basis of chronologically-based, using as follows Two ways divides massage set：

First way, massage set is divided based on default size.

Wherein, default size can in advance be configured or changed, and the present embodiment is not construed as limiting to this.Such as, this is preset Size can be 80M so that can be divided to word message record in multiple word message set by the second equipment, and media are disappeared Breath record is divided in multiple media information set.Specifically, according to the difference of Message Record type, the division of the massage set It is divided into two kinds of situations again：

The first situation, when Message Record is recorded for word message, the word Message Record is being added to the word Before massage set, by indicated by the word massage set and the word massage set media information record total size with should Default size is compared, if the total size is less than the default size, the word Message Record is added into the word and is disappeared In breath set；Otherwise, the word Message Record is added to a new word message set.

Second situation, when Message Record is recorded for media information, add by the description information that the media information is recorded Before being added to the word massage set, by indicated by media information record, word message set and the word massage set The total size of media information record is compared with default size, if the total size is less than the default size, by the media The description information of Message Record is added in text massage set, and media information record is added into corresponding media information In set；Otherwise, the description information that the media information is recorded is added to a new word message set, by the media information Record is added to a new media information set.Additionally, the second equipment can also be using a media information record as one Media information set, the present embodiment is not construed as limiting to this.

The second way, massage set is divided based on presetting message number.

The presetting message number can in advance be configured or changed, and the present embodiment is not construed as limiting to this.Such as, the present count Mesh can be 2000, then according to the difference of Message Record type, the division of the massage set is divided into two kinds of situations again：

The first situation, when Message Record is recorded for word message, the word Message Record is added to word message Before set, the second equipment detects whether the Message Record number included in the word massage set is less than the presetting message number Mesh, if it is less, the word Message Record is added in the word massage set；Otherwise, the word Message Record is added It is added in a new word message set.

Second situation, when Message Record is recorded for media information, then the description information that the media information is recorded is added Before being added to word message set, the second equipment detects whether the Message Record number included in the word massage set is less than The presetting message number, if it is less, the description information that the media information is recorded is added in the word massage set, will Media information record is added in corresponding media information set；Otherwise, the description information addition for the media information being recorded To in a new word message set, media information record is added in a new media information set.Additionally, the Two equipment can also be using a media information record as a media information set, and the present embodiment is not construed as limiting to this.

It should be noted that in the case of two kinds of the second way, the description letter of media file in word message set Breath also illustrates that a piece of news is recorded.

In the present embodiment, the second equipment can use file to be transmitted to massage set for carrier, so as to carry out data Backup.Wherein, multiple massage sets can constitute a message file, such as, multiple word message collection can be combined into one Multiple media information collection are combined into a media information file by individual word message file.

207th, for each massage set at least one massage set, the second equipment determines that the message of the massage set refers to Show information, message configured information is used to indicate the generation time of the last item Message Record in the massage set.

For each massage set, according to the generation time of Message Record, the second equipment can be determined in the massage set The generation time of the last item Message Record.
