Step S111 creates three files, respectively info file, warning file and fatal file.
Wherein, which is
Relationship incremented by successively.Wherein, fatal file is for storing in its interior log information comprising fatal class log critical field
The backup file of such as error, invalid；Warning file is used to store in its interior log information
The backup file of warning class log critical field such as timeout, warning etc.;Info file is for storing its interior log
The backup file of fatal class log critical field and warning class log critical field is not included in information.
Step S112 searches the log critical field of log information in backup file, and according to class in log critical field
The different of type store backup file into corresponding document folder.
Wherein, namely if log information includes fatal class log critical field in backup file, file will be backed up
(referred to as fatal class backup file) is stored to fatal file;If log information only includes in backup file
Warning class log critical field then stores backup file (referred to as warning class backup file) to warning file
Folder;If log information had not only included fatal class log critical field but also had not included the log of warning class and closed in backup file
Key field then stores backup file (referred to as info class backup file) to info file.
Preferably, synchronous when will include that the backup file of fatal class log critical field is stored to fatal file
Triggering alarm is to prompt user.Wherein, citing can be accused by Communications services such as triggering mail, wechat, short message, phones
It is alert.
It in step s 12, further comprise as follows specifically among the step of clearing up backup file according to the rule of setting
Step:
Step S121, timing detection disk have used space.Wherein, three files typically set up and are stored in same disk
Under.
Step S122 judges the threshold value for whether reaching setting with space of disk.If disk is reached with space
Threshold value then enters step S123；Otherwise, S121 is entered step, namely does not need to clear up backup file, it is only necessary to be supervised again
Control disk space.
Step S123 then deletes respective backup file according to the significance level of backup file and generation time sequencing
Or transfer.
In step S123, preferably first deletion significance level is lower, generates the time backs up file earlier.For example, first deleting
Remove or shift the info class backup file being stored under info file generated before the first scheduled date；If detecting and sentencing
Break and still reach threshold value with space to disk, then deletes or what is generated before shifting for the first scheduled date is stored in warning
Warning class backup file under file；If detecting and determine disk still reaching threshold value with space, continue to delete
The info class backup file that (being later than for the first scheduled date) generates before removing or shifting the second scheduled date；If detecting and judging
Still reach threshold value with space to disk, then it is standby to continue the warning class deleted or generated before shifting for the second scheduled date
Part file ...；Until the info class backup file and warning class backup file that are generated before retaining a certain scheduled date；If
It detects and determine disk still reaches threshold value with space, then delete or what is generated before shifting the third scheduled date is stored in
Fatal class backup file under fatal file；If detecting and determine disk still reaching threshold value with space, delete
The fatal class backup file that (being later than the third scheduled date) generates before removing or shifting the 4th scheduled date；Until retaining a certain
The fatal class backup file generated before scheduled date.
Preferably, complete institute with good grounds backup file significance level with generation time sequencing to respective backup file into
Row delete or transfer the step of after, namely deleted according to preset rules can not delete or do not have transferable backup file after,
If detecting and determine disk still reaching threshold value with space, alarm is triggered to prompt user to make resolution policy.Its

More than 70%, then the warning class backup file before (parameterisable configuration) on the 30th is deleted；If disk sky after deleting
Between still above 70%, then delete (parameterisable configuration) on the 10th before info class backup file；If disk has been used after deleting
The warning class backup file before (parameterisable configuration) on the 10th is then deleted still above 70% in space；If magnetic after deleting
Disk has used space still above 70%, then deletes the info class backup file before (parameterisable configuration) on the 3rd；If after deleting
Disk has used space still above 70%, then deletes the warning class backup file before (parameterisable configuration) on the 3rd；If deleted
Except rear disk has used space still above 70%, then the fatal class backup file before (parameterisable configuration) on the 90th is deleted；Such as
Disk has used space still above 70% after fruit is deleted, then the fatal class before deleting (parameterisable configuration) on the 30th backs up text
Part；If disk has used space still above 70% after deleting, mail or wechat alarm are triggered.
In one embodiment, the step of the size of the fixed time inspection journal file of setting is specifically pressed in step S2
Among rapid, which can be endowed as a fixed value.
In a preferred embodiment, the fixed time interval be also designed as one can be according to log writing speed and day
