Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear
Chu, it is fully described by.
Embodiment one
A kind of file backup method provided in an embodiment of the present invention, applied to terminal, the terminal include mobile phone,
Notebook computer, tablet personal computer, LCD TV, game machine even include vehicle-mounted computer machine, as shown in figure 1,
This method includes：
Step 101, obtain file to be stored fileinfo and storage file take memory space.
Here, fileinfo includes the first space that file to be stored takes, and storage file includes having stored
Source file and backup file is stored.Wherein, stored source file refer to it is stored in storage device
Source file；Backup file has been stored to refer to carry out secondary storage to the important source file that stored in storage device,
Form the important backup file for having stored source file.Source file refers to that corresponding software and realization pair can be started
Answer the file of function.Backup file is equivalent to the duplication to corresponding source file.
User can store source file by terminal access, when user has stored source file by terminal access,
Terminal system finds that the source file of storage to be accessed can not read or be damaged, then terminal system can turn
And access to have stored and backup file has been stored corresponding to the source file, so as to realize the access.Meanwhile terminal
System can also store backup file to that can not read or the impaired source file that stored is repaiied using this
It is multiple, so as to the access after user.
Example, as shown in Fig. 2 so that terminal access has stored source file as an example, the execution of terminal applies layer
Process includes：
Step 1011, reading have stored source file.
Here, the application layer of terminal system is to have stored source file by the reading interface of system to read.
Step 1012, judgement have stored whether source file reads success, if so, then performing step 1015；It is no
Then perform step 1013.
Step 1013, reading have stored backup file accordingly.
When terminal system finds that having stored source file can not successfully read, just go to read and this has stored source document
Part has stored backup file accordingly.Specifically, it is to read to have stored from flash memory (Flash Memory)
Source file and backup file is stored.
Step 1014, basis have stored backup file, and reparation has stored source file accordingly.
This has stored backup file and can not only read for terminal system, can also be to having stored source file accordingly
Repaired, so as to reading afterwards.
What deserves to be explained is if when reading has stored source file exception, it is available to have stored backup file pair
The reparation of source file has been stored, the reparation can also be placed under system idle condition and completed,
Step 1015, update the visitation frequency for having stored source file.
Storage source file-related information, such as visitation frequency are also deposited in storage device, whenever to having deposited
Source of bank savings file read once, visitation frequency just add up 1.
What deserves to be explained is source file and backup file are stored in identical storage device, that is, it is stored in
In memory space.Wherein, source file is visible to user；And it can be not for a user to back up file
It is visible, it is only visible to the backstage of terminal system.
Here, file to be stored includes source file to be stored and backup file to be stored, here in two kinds of situation：
Situation one：File to be stored is source file to be stored.
When such case refers to create source file first, file to be stored is just source file to be stored.Show to deposit
Storage equipment does not store the source file to be stored before, is ready for storing the source file to be stored now
Into storage device.
Situation two：File to be stored is backup file to be stored.
On the one hand, illustrate that having stored source file has been stored in storage device, then and then or
Source file is stored under predetermined condition to this to back up, i.e., file to be stored is backup file to be stored.
On the other hand, terminal system finds some important storage source file, and in memory space simultaneously
Corresponding backup file is not found, then the storage source file that now terminal system will be important to this
Backed up, file to be stored is just backup file.
Step 102, according to the first space and memory space, the minimum backup of storage of release severity level
Free up Memory shared by file.
Specifically, as shown in figure 3, terminal according to the first space and memory space, release severity level is most
The low Free up Memory stored shared by backup file includes：
Step 1021, judge whether the first space is more than remaining space；If so, then perform step 1022；It is no
Then perform step 1024.
Here, remaining space is the space in the gross space of storage device in addition to memory space.
Step 1022, the listed files information for obtaining storage file.
Step 1023, according to listed files information, shared by the minimum backup file of storage of release severity level
Free up Memory.
Step 1024, directly store file to be stored.
, it is necessary to judge whether the remaining space of storage device is enough before storage file to be stored, that is, need to compare
Whether it is more than remaining space compared with the first space.
When the first space is less than or equal to remaining space, illustrate that the remaining space of storage device is enough to store
The file to be stored, directly the file to be stored is stored in the storage device；
When the first space is more than remaining space, then shows that the remaining space of storage device is too small, do not store
The file to be stored.Terminal system can perceive the situation in time, and can take a series of measure,
So that the file to be stored is stored in storage device.Specifically, terminal system can delete weight in storage device
Want the backup file of storage that rank is minimum, severity level is minimum has stored shared by backup file for release
Free up Memory, so as to store the file to be stored.So, allow for depositing in storage device in a sense
More more important and significant file is stored up, so as to be preferably user service.
Before the minimum Free up Memory stored shared by backup file of release severity level, it is necessary to from
The minimum backup file of storage of severity level is identified in storage file, and has stored the important of backup file
Rank is to depend on corresponding storage source file, when stored source file it is more important indicate that corresponding to
The severity level for having stored backup file is higher.What deserves to be explained is can also be deposited in storage device and some
The related listed files information such as file, this document list information be differentiate storage source file importance according to
According to.
Judgement for storage source file importance is a process for carrying stronger subjective factor, also can be by
User freely defines, and is to vary with each individual, may be with the close phase such as the personal profession of user, hobby, custom
Close, the present embodiment does not limit.Preferably, in the present embodiment with to stored source file visitation frequency and
The creation time for having stored source file is judgment basis.
Here, listed files information is used to identify the severity level for having stored source file, listed files packet
Include the visitation frequency and creation time for having stored source file corresponding to backup file.Specifically, acquisition is all
Store the visitation frequency and creation time of the source file corresponding to backup file；Backup text has been stored according to all
The access times of source file corresponding to part and it is all stored the source file corresponding to backup file establishment when
Between, determine the minimum backup file of storage of severity level；Discharge the minimum backup text of storage of severity level
Free up Memory shared by part.
What deserves to be explained is in storage device, storage file includes having stored source file and having stored standby
Part file, wherein, the total number for having stored source file is more than or equal to the total number for having stored backup file.
Specifically, as it is all stored backup file corresponding to source file access times and all stored
The order arrangement incremented by successively of the creation time of source file corresponding to backup file is all to have stored backup file
Corresponding source file, form source file sequence；It will be deposited corresponding to preceding m source file in source file sequence
Deposit part file mark is that severity level minimum m has stored backup file, severity level minimum m
The difference that the space shared by backup file is more than or equal to the first space and remaining space is stored, m is less than
Store the positive integer of backup file total number.
After the minimum m of release severity level is individual has stored the space shared by backup file, the severity level is most
The m low spaces stored shared by backup file and original remaining space collectively constitute new remaining space,
Now, new remaining space is necessarily more than or equal to the first space.In other words, the minimum m of severity level
The individual space stored shared by backup file is greater than or equal to the absolute value of the difference of the first space and remaining space,
Memory space is enabled to store the file to be stored.It is what deserves to be explained is minimum when only discharging severity level
M-1 stored the spaces shared by backup file after, new remaining space is still small as before release
In the first space, i.e. the minimum m-1 of the severity level spaces stored shared by backup file are less than first
The absolute value of the difference of space and remaining space, storage device can not store the file to be stored.
Step 103, storage file to be stored.
In Free up Memory and remaining space, the storage of file to be stored is completed, that is, stores file to be stored.
Before step 102, methods described also includes：It is periodically detected and has stored the second of source file occupancy
Space；According to second space and gross space, the minimum backup file of storage of forcible aborting severity level.
Specifically, as shown in figure 4, terminal according to second space and gross space, forcible aborting severity level is most
The low backup file of storage includes：
Step 1021 ', obtain second space and gross space.
Step 1022 ', calculate second space and account for the accounting of gross space.
Step 1023 ', judge whether accounting is more than predetermined threshold value；If so, then performing step 1024 '；Otherwise
Perform step 1021 '.
Preferably, predetermined threshold value takes 50%.
Step 1024 ', obtain the minimum backup file of storage of severity level.
Here, the number for having stored backup file that acquired severity level is minimum is pre-set by user,
Can be between 1 and to have stored the random natural number between backup file total number.
Step 1025 ', the minimum backup file of storage of release severity level.
Here, the minimum backup file of storage of severity level in release steps 1024 ' is refered in particular to.
After step 103, methods described also includes, the listed files information in the storage device that upgrades in time.
