Referring to Fig. 2, another embodiment of data back up method includes in the embodiment of the present invention：
201st, the running status of destination application is detected；
Step 101 in step 201 embodiment corresponding with Fig. 1 is identical, and here is omitted.
If the 202, detecting destination application to be transferred to after running background, record destination application from front stage operation
Platform operation duration；
During being detected to the running status of destination application, if detecting destination application from foreground
Running background is transferred to, then can record the running background duration of destination application.Specifically, intended application can detected
When program is transferred to running background from foreground, timer is opened, duration is recorded, is used as running background duration.
If the 203, running background duration is more than or equal to preset duration threshold value, the data to destination application are carried out
Backup, to obtain Backup Data；
When the running background duration of record is more than or equal to preset duration threshold value, the data to destination application are carried out
Backup, to obtain Backup Data.Preset duration threshold value can be fixed, or user-defined, not limit herein
It is fixed.
On preset duration threshold value, it is necessary to consider that following factor is rationally set：Threshold value is smaller, the possibility of loss of data
Property it is lower, limiting case is not perform step 202, is being detected when destination application is transferred to running background just directly to mesh
The data of mark application program are backed up, but threshold value is smaller, and the possibility of the wasting of resources is bigger, because in the running background time
The probability that shorter application program is closed by system is very low；Conversely, threshold value is bigger, the possibility of the wasting of resources is smaller, but number
It is bigger according to the risk of loss.In addition, preset duration threshold value can be according to the different and different of destination application, such as excellent
The higher destination application of first level, preset duration threshold value can be smaller, and for the relatively low destination application of priority, in advance
If duration threshold value can be with larger.
Data on backup refer to the description content of step 102 in the corresponding embodiments of Fig. 1, and here is omitted.
If the front stage operation instruction of destination application the 204, is received, using Backup Data to destination application
Data are recovered, and control targe application program runs on the foreground of terminal.
After the data of destination application back up obtaining Backup Data, destination application may continue to keep
Background operation state, it is also possible to be closed and in off-duty state (such as because user imprudence remove background application or
Person's terminal closes the destination application of running background automatically), when the front stage operation for receiving destination application is instructed,
Backup Data can be used to recover the data of destination application, and control targe application program is run on before terminal
Platform.
Application program still suffers from data and updated during running background, such as the downloading task of running background, with
The extension of time, the data downloaded from server are continuously increased, such as the wechat of running background is still obtained in real time from server
Take the chat message of renewal.When destination application is in background operation state, the data to destination application carry out one
Secondary backup is obtained after first time Backup Data, if destination application continues for running the long period on backstage, now mesh
The data of mark application program differ greatly with first time Backup Data, only preserve first time Backup Data, it is impossible to avoid loss standby
Continue the data updated after part.In order to solve this problem, referring to Fig. 3, data back up method is another in the embodiment of the present invention

If the 302nd, detect destination application is transferred to running background from front stage operation, and running background duration be more than or
Equal to preset duration threshold value, then the data of destination application are backed up according to prefixed time interval, it is multiple standby to obtain
Number evidence；
During being detected to the running status of destination application, if detecting destination application from foreground
Running background is transferred to, and running background duration is more than or equal to preset duration threshold value, then can be according to prefixed time interval to mesh
The data of mark application program are backed up, to obtain multiple Backup Datas.Such as, at the t1 moment, the backstage of destination application
Operation duration is equal to preset duration threshold value, the data of destination application can now be backed up, obtain Backup Data 1；
At the t2 moment, compared with the t1 moment and have passed through prefixed time interval, the data of destination application can now backed up,
Obtain Backup Data 2；At the t3 moment, compared with the t2 moment and have passed through prefixed time interval, now can be to intended application journey
The data of sequence are backed up, and obtain Backup Data 3, the like, it is not in running background up to detecting destination application
Only, it is assumed that obtain 5 Backup Datas, i.e. 1~Backup Data of Backup Data 5.Above only as an example, in actual use, it is not necessary to
Start backup when the running background duration of destination application is equal to preset duration threshold value, can also be grown up in running background
Backup is sometime proceeded by after preset duration threshold value.
Prefixed time interval can be fixed, or user-defined, not limit herein.During on presetting
Between interval, it is necessary to consider that following factor is rationally set：Prefixed time interval is smaller, and the possibility of loss of data is lower, but
It is bigger to the occupancy of system resource, it is necessary to frequently perform backup operation, takes a large amount of memory spaces；Conversely, preset time
Interval is bigger, and the occupancy of resource is smaller, but the risk of loss of data is bigger.In addition, prefixed time interval can be according to target
Application program it is different and different, such as the higher destination application of priority, prefixed time interval can be smaller, and
For the relatively low destination application of priority, prefixed time interval can be with larger.
It should be noted that in actual use, backstage fortune can also be transferred to detecting destination application from foreground
During row, just directly the data of destination application are backed up according to prefixed time interval, to obtain multiple Backup Datas, and
Without being performed after being more than or equal to preset duration threshold value in running background duration.Reason see the corresponding embodiments of Fig. 2

If the 303, receiving the front stage operation instruction of destination application, multiple backup numbers of destination application are obtained
According to and be shown；
The data of destination application are backed up according to prefixed time interval, with after obtaining multiple Backup Datas,
Destination application may continue to keep background operation state, it is also possible to be closed and in off-duty state (such as because with
Family imprudence removes the destination application that background application or terminal close running background automatically), when receiving target
During the front stage operation instruction of application program, multiple Backup Datas of destination application can be obtained and be shown.In this hair
In bright embodiment, as an example, 1~Backup Data of Backup Data 5 can be shown.It should be noted that to backup number
It is not limited to be shown all the elements of Backup Data according to being shown, it is preferred that can only show Backup Data pair
The backup time answered, corresponding Backup Data is represented with backup time.Assuming that the corresponding backup of 1~Backup Data of Backup Data 5
Moment is followed successively by t1, t2, t3, t4, t5, then, user can be showed using t1, t2, t3, t4, t5 as five options, for
Family is selected.
304th, the selection instruction of a Backup Data in multiple Backup Datas for displaying is received；
After user selects a Backup Data from the Backup Data of displaying, it can receive for the multiple standby of displaying
The selection instruction of number Backup Data in.Assuming that being shown in step 303 using t1, t2, t3, t4, t5 as five options
To user, selected for user, if user selects t1, can determine that user selects from 1~Backup Data of Backup Data 5 standby
Number evidence is Backup Data 1.
305th, the data of destination application are recovered using a Backup Data corresponding with selection instruction, and controlled
Destination application processed runs on the foreground of terminal；
Receive and be directed in multiple Backup Datas of displaying after the selection instruction of a Backup Data, can select and select
Instruct a corresponding Backup Data to recover the data of destination application, such as receive the choosing to Backup Data 1
Select after instruction, Backup Data 1 can be used to recover the data of destination application, and control targe application program is transported
Row is in the foreground of terminal.
306th, other Backup Datas in multiple Backup Datas beyond a Backup Data corresponding with selection instruction are deleted.
After step 304, it may be determined that the corresponding Backup Data 1 of selection instruction by the recovery for destination application,
And other non-selected Backup Datas (2~Backup Data of Backup Data 5) continue the value preserved not in multiple Backup Datas
Height, in order to save the memory space of terminal, after the step 304, can delete corresponding with selection instruction in multiple Backup Datas
A Backup Data 1 beyond other Backup Datas (2~Backup Data of Backup Data 5).Therefore, as long as step 306 is in step
Performed after rapid 304.
