Specifically, workflow of the present invention comprises:
The first step: the terminal is arrived the cloud computing end through mobile communications network with information uploadings such as personal information and multimedia files;
Second step: the cloud computing end carries out back-up storage with the information that upload at the terminal, and fresh information is labeled as new version information according to the information synchronization strategy, preserves incremental update information (being equivalent to above-mentioned incremental data) simultaneously.Typical synchronization policy comprises active synchronization, cloud computing end given content synchronous of one-way synchronization to the one-way synchronization in high in the clouds, cloud computing end to the terminal of the bi-directional synchronization, terminal of terminal and cloud computing end, the triggering of cloud computing end.
Wherein, the cloud computing end is preserved increment synchronous version number.The form of increment synchronous version number is " the effective updated space in cloud computing end/terminal-cloud computing client information version number-end message version number-update time ", and wherein the final updating of " the effective updated space in cloud computing end/terminal " expression information is to carry out by the cloud computing end or at the terminal; " cloud computing client information version number " is the version number by the control of cloud computing end, and like the cloud computing end information being made amendment then increases " cloud computing client information version number "; " end message version number " is the version number by terminal control, and the terminal then increases " end message version number " as information is made amendment.

1) terminal judges that according to " the effective updated space in high in the clouds/terminal " whether the terminal has modification to the information of last revision; In this way, then send own increment synchronous version number and increment information to the cloud computing end, as not, then only the increment synchronous version of transmission oneself number to the cloud computing end.
If the information of end side changes, will upgrade terminal information and increment synchronous version number, promptly only keep a latest edition at the terminal.
2) the cloud computing end will need the increment synchronous version comparison at synchronous increment synchronous version number and terminal, as identical, then notify the terminal need not upgrade; Like difference, then the cloud computing end search information that needs synchronous increment synchronous version number is with respect to the incremental data between the information of the increment synchronous version at terminal number.
The information that increases a redaction in the cloud computing end can trigger increases corresponding record (that is, in the synchronous list of modification record of increment new version number) in the synchronous list of modification of increment.When subsequent treatment, whether the information that can judge this version fast has backup at the cloud computing end.
If search, then said incremental data and increment synchronous version number are issued the terminal, make said terminal preserve increment synchronous version number in this locality, as the current version of information number; And according to incremental data renewal local information.
As do not search, then the cloud computing end information that calculate to need synchronous increment synchronous version number is issued the terminal then with respect to the incremental data between the information of the increment synchronous version at terminal number.
Wherein, above-mentioned steps 1) in, the information of end side is revised, and it is number following with the step of incremental data to send the increment synchronous version to the cloud computing end:
1) terminal increases corresponding record to the modification of the synchronous information of need in the triggering synchronous information-change table;
2) incremental data of the synchronizing information list of modification at terminal inquiry terminal preservation; Wherein incremental data comprises: the version number of the information of two comparison versions, synchronizing information title (like address list), synchronizing information identifier (like which row in the sign text, which bar in the address list), information-change action identification (comprising increase information, deletion information, modification information), modification content (for example being revised as " 1 ").
3) terminal is to sending increment synchronous version number and incremental data with the cloud computing end.
4) mobile terminal and cloud computing end synchronously after, the incremental data in the synchronizing information list of modification of mobile terminal is cleared.
In the foregoing description, the version number of information can define according to timestamp.
The present invention has the following advantages:
1) utilizes the mass memory and the powerful disposal ability of cloud computing system, can support the information synchronization of great amount of terminals simultaneously;
2) the cloud computing end backs up the information of a plurality of versions, makes terminal information possess the function of rollback synchronously, and synchronizing information that can query history also can be synchronous with historical information, helps the collaborative work between different terminals;
