It is above-mentioned that the local file of terminal device is replicated according to time interval, and store into specified directory step,
Terminal device carries out local file according to the time interval timing of the preset time interval of user either system default
Replicate and obtain backup file (can be described as new backup file), then judge in specified directory whether existing backup file, such as
The existing backup file of fruit (can be described as former backup file, i.e., the backup file that last backup generates), and new backup file is made to cover
The former backup file of lid will directly replicate obtained backup file and be stored directly in if backup file is not present in specified directory
In specified directory, the backup file before the file of newest backup can cover again every time in this way ensures to store in specified directory
Newest backup file.For example, being answered local file (such as database file of cabinet-type air conditioner application) when user can be arranged
The time interval of system is 5 minutes, and terminal device once obtained backup file at interval of 5 minutes to local file duplication, then sentenced
In disconnected specified directory whether existing backup file, if it does, making new backup file covering original backup file, and preserve；If
Backup file is not present in specified directory, then will directly replicate obtained backup file and be stored in specified directory.
When there is local file exception in terminal device, such as the scenes such as mainboard is burnt out, equipment replacement, terminal device at this time
It can not work normally.At this point, terminal device can identify from specified directory and obtain backup file, then, backup text is used
Part replaces abnormal local file.After the completion of replacement, terminal device will restore to work normally, and regain local file
(backing up file).Or there is the phenomenon that database file damage in operation in terminal device application, then when data library text
When damaging or having exception that cannot normally read and write occur in part, newest backup text is obtained from the local specified directory triggering appointed
Part can ensure to substitute the database file of damage using continuation normal operation.

Make.
Preferably, described that the local file of terminal device is uploaded to background server, and be stored in background server
The step of include：
Local file is uploaded to background server by terminal device timing；
Background server is compared and is corrected to the local file uploaded, is then stored.
In the step of local file is uploaded to background server by terminal device timing, since terminal device is being held
When row operation, operation note can be all uploaded to background server, when background server receives the operation note of upload, to it
It is preserved, such as the operation of user on the terminal device, terminal device can all upload to background server in time, and on backstage
Server obtains appropriate record, keeps the synchronism of background server data and terminal device data；Terminal device is applied
Every time start after with it is unattended when, can timing by its data information synchronous driving to background server.When by presetting
Between be spaced or timing local file is uploaded to background server by system default time interval, terminal device.
The step of platform server compares the local file uploaded and is corrected, then stored in the rear
In, background server is first corrected it after the local file for receiving terminal device upload, for example, modification terminal is set
The standby time etc. judges whether existing backup file makes new backup file if existing backup file in background server
The former backup file of covering will directly replicate obtained backup file and be stored in if backup file is not present in background server
In specified directory.
By three kinds of above-mentioned modes, can the local file of terminal device be backed up and is stored in specified in advance
In catalogue, when the local file of terminal device is abnormal, abnormal local file is replaced by backup file in time, makes end
The case where end equipment restores normal work, avoids loss of vital data, and terminal device can not work.
All it is first to judge before storage in above-mentioned three kinds of modes that local file is backed up and stored in advance
In specified directory whether existing backup file, if it does, making new backup file covering original backup file, and preserve；If no
In the presence of backup file, new backup file is made directly to preserve.However, in practical application, user may restore a certain as needed
The local file at a time point cannot be satisfied the demand of some users if being carried out covering operation every time.
So the present invention also provides a kind of real-time proposals：Local file is backed up and deposited in advance at above-mentioned three kinds
In the mode of storage, when obtaining new backup file every time, original backup file is not covered, but again by new backup file
Name, is stored in specified directory, when equipment is abnormal, user can be as needed, selects some time point together
Backup file, and restored, terminal device made to restore normal work.Specific step can be that user presets to text
The time interval that part is replicated either by system default and selects specified directory, for example, be divided between setting time 1 hour,
Local file is backed up in advance by above-mentioned three kinds and carry out storage mode one of which or wherein it is several obtain it is standby
Part file is simultaneously stored in specified directory, when storage, need not judge whether backup file again, but by new backup file
It renames, such as it can be named according to the priority of doubling time, subsequent calling etc. can be facilitated in this way.Name is completed
Afterwards, it is stored.When terminal device is abnormal, user can select arbitrary a backup in specified directory as needed
Then file restores it into terminal device, terminal device is made to restore normal work.For example, before selection restores 48 hours
Local file etc..In this way, user can be as needed, selection restores the local file at some time point.Certainly, user goes back
The effective time of the storage of backup file in specified directory can be set, such as sets effective time as 3 months, then all
The effective time of backup file storage is that system will be automatically deleted the backup that storage time is more than 3 months after 3 months, 3 months
File, and backup file is stored again.In such manner, it is possible to effectively solve the problems, such as that backup file is excessive, memory space inadequate.
For the terminal device that some are frequently used, it is higher than the terminal device that some are used once in a while to there is abnormal frequency.
If using same time interval, such as every 30 minutes replicate local file and are obtained backup file, then, it may
Will appear some terminal devices frequently used, time interval this period of time in be abnormal, but not in time into
Row replicates, and leads to the important local file being lost in this period of time and can not restore；And the terminal that some are used once in a while
Equipment causes the waste of memory space it is possible that the file that continuous several time intervals replicate is the same.Needle
To this problem, user can set the time interval replicated to local file according to the frequency of use of terminal device.Tool
A cycle can be arranged in body, statistically the terminal device access times in a cycle, and according to statistical result to this period
Interior doubling time interval is adjusted.For example, setting the period be a week, then when on terminal device a week it is total
When access times are more than 0 time and are less than or equal to 100 times, this week replicated at interval of 1 hour local file to terminal device
Once, it obtains backup file and is stored in specified directory；When total access times in a week on terminal device are more than 100 times
And when less than or equal to 1000 times, this week replicated once at interval of 30 minutes local files to terminal device, was backed up
File is simultaneously stored in specified directory；When total access times in a week on terminal device are more than 1000 times, this week is every
It is spaced 15 minutes local files to terminal to replicate once, obtains backup file and be stored in specified directory.In this way, frequently making
Terminal device can timely back up local file, avoid because time interval is long, the local of lost part
File；The continuous several time intervals that the terminal device used once in a while also avoid, which replicate to obtain backup file, is the same feelings
Condition.
Preferably, the step S2 is specifically included：
S21, when terminal device reinstall in application, from background server obtain backup file；
S22, backup file is covered into original local file.
In the step S21, when terminal device is reinstalled in application, local file will be null file, at this time eventually
If end equipment wants to restore original local file, backup file can be obtained from background server.Can be specifically, terminal device
The request for restoring local file is sent to background server, after background server receives request, it is verified, such as core
Unique mark, legitimacy of real terminal device etc. after verifying successfully, respond the request of terminal device, this terminal device institute is right
The backup file answered is sent to the terminal device.
In the step S22, after terminal device gets the backup file of background server transmission, backup file is covered
Cover original local file.At this point, terminal device successfully restores the local file before exception, can continue to provide clothes for client
Business.
For example, when terminal device application is reinstalled, can all be lost using existing data information, at this time terminal device
Data information will be brand-new blank.If wanting to give the data information before this station terminal equipment for change, to continue normally for user
Service is provided, then may be selected by restoring to terminal to set by the backup file synchronization in background server when application is installed
Standby, such terminal device can remove the backup file for pulling background server about the station terminal equipment, be written to the terminal device
In, such terminal device has just restored previous record.
Preferably, in the S21, when terminal device is reinstalled in application, local file is uploaded to background server,
To generate backup file.
In the step S21, when terminal device is reinstalled in application, local file will be null file, at this time eventually
If end equipment is wanted to thoroughly remove the history usage record of terminal device, and can remove the backup stored in background server
File.Since the local file of terminal device at this time is blank, local file is uploaded to background server at this time, backstage takes
After business device receives the local file of terminal device upload, the local file of blank can be covered original backup file and obtained newly
Backup file, the new backup file preserved in background server at this time be null file.In this way, terminal device is using brand-new
The record of blank can cover the data record of background server, then all accent starts again, to make background server and end
The data of end equipment remain.And when terminal device sends the request for restoring local file to background server again, it obtains
The backup file obtained is null file, backup file is then covered original local file, after the completion of covering, terminal is set
Standby local file is consistent by the backup file with background server, is null file.
