Backup database can preserve the synchrodata of 50-60 items, when being continuously increased new synchrodata and corresponding synchrodata
When identification information, due to backup database limited memory, more early it can will preserve and surpass according to the holding time of synchrodata
The synchrodata limited is crossed to be automatically deleted；Alternatively, by the connection of first server and terminal, user can pass through the aobvious of terminal
Show and synchrodata is independently deleted, to delete the smaller synchrodata of some significance levels.
Work as user misoperation, when the first synchrodata being caused to be lost, in general, the first synchrodata of loss is
It can not give for change.In the present embodiment, this can be solved the problems, such as.In terminal the second same step number of preservation synchronous with sync database
According to when, which is sent to first server by second server, and first server again protects the second synchrodata
There are in backup database.Wherein, second server is the server where sync database；Sync database is same with terminal
The database of step；Second synchrodata is any bar synchrodata, may include the first synchrodata.
It should be noted that first server is for preserving backup database, second server is for preserving synchrodata
Library.Backup database can be in identical server with sync database, i.e., first server and second server are same
Server；Backup database and sync database can also be in different servers, i.e. first server and second server
For different servers.
When backup database and sync database in a server when, server inquires the in backup database
When one synchrodata, the first synchrodata is sent to sync database, and first synchrodata is preserved by sync database.
When backup database is stored in first server, and sync database is stored on second server, when first
When server inquires the first synchrodata in backup database, the first synchrodata is sent to the second clothes by first server
First synchrodata is stored in sync database by business device, second server again.
In the present embodiment, it is described in different servers from sync database with backup database.
Step 203, first synchrodata of inquiry is sent to second server by first server, and second server is again
First synchrodata is stored in sync database；
Specifically, as shown in figure 3, the first synchrodata is stored in the step in sync database such as by second server
Under：
Step 301, second server receives the first synchrodata that first server is sent；
When first server inquires corresponding first by the identification information of the first synchrodata in backup database
After synchrodata, the first synchrodata is sent to second server by first server, so as to the same step number in second server
The first synchrodata is preserved according to library.
Step 302, second server receives the identification information for the current sync data that terminal is sent；
The identification information of current sync data indicates to preserve the identification information of newest synchrodata in the terminal.
Step 303, according to the identification information of current sync data, second server determines the mark letter of current sync data
Next identification information of breath is the newest identification information of the first synchrodata；
In this step, the information that the identification information of synchrodata includes has：Preserve specific time, the synchronization of synchrodata
The quantity of data, the affiliated type of synchrodata.For example, the type of the first synchrodata is news type, current sync data
Identification information for news type is 121101103, it may be determined that the newest identification information of the first synchrodata is
121101104。
Step 304, it when the first synchrodata is stored in sync database by second server, determines and preserves the first same step number
According to current time be synchrodata newest identification information；

So it can also indicate step 303 with dotted line frame.
Step 305, the newest identification information of the first synchrodata and the first synchrodata are stored in sync database.
It should be noted that the operating method of step 301- steps 305 is that the first synchrodata is stored in synchrodata
Step in library continues to execute step 204 after being stored in sync database to the first synchrodata.
Step 204, in the first synchrodata simultaneous display to terminal sync database preserved；
When terminal preserves the identification information of the second synchrodata, the second synchrodata is any bar synchrodata, corresponding
, the identification information of second synchrodata and the second synchrodata of corresponding identification information are preserved in sync database；
Corresponding when the identification information of terminal synchronization removal the second synchrodata of any bar, synchronization removal should in the second database
Second synchrodata of the identification information of the second synchrodata and corresponding identification information.First server will inquire first
Synchrodata is sent to second server, when the first synchrodata is stored in sync database by second server again, due to end
The synchronized links at end and second server can preserve the identification information of the first synchrodata, and display first in the terminal
Synchrodata.
Step 205, second server believes the newest mark of first synchrodata of preservation and the first synchrodata
Breath is sent to first server, and first server again protects the newest identification information of the first synchrodata and the first synchrodata
There are in backup database.
When the first synchrodata is stored in sync database again, and when with newest identification information, illustrate this first
Synchrodata has been successfully recovered.
After the first synchrodata is successfully recovered, the newest mark by first synchrodata and the first synchrodata is needed
Know information and be sent to first server, first server again believes the newest mark of the first synchrodata and the first synchrodata
Breath is stored in backup database, so that backup database preserves the newest mark of the first synchrodata and the first synchrodata
Information improves the information of whole second synchrodatas in backup database in time.
