Existing file backup method, be mainly that the user sets backup target as required, and backup target is carried out in real time or monitoring regularly, finds that file has modification, carries out fully or incremental backup, reached the purpose of backup file.
But in actual backup procedure, the existing file backup method has the following disadvantages:
1, backup target is set complexity, generally needs setting to need the catalogue that backs up, the file type that needs backup, do not need the sub-directory that backs up, do not need the file type that backs up; Which catalogue general user may know own important data in, but selects have what type just not too easy again.The document that produces such as word has doc, and docx, be not easy to understand this difference of two types concerning the user.
2, monitoring has regularly and real-time two kinds of methods traditional file backup system to backup target.If timed backup, need the modification time of All Files in scanning directory during to BACKUP TIME point, CPU usage is high consuming time long with scanning.If back up in realtime, the read-write operation that needs all processes in the Real Time Monitoring file system, whether decision operation is the target that backs up for needs, and the General System process is more frequent to the read-write operation of system, nonsensical to its monitoring, only can affect system effectiveness.
When if 3 users need to dispose backup scenario in batches, be difficult to cook up unified policy template, because the work habit of different user is different, the position of depositing significant data is different, so be difficult to set unified strategy.
4, the user in the course of the work, if forget vital document is stored in and needs the backup target catalogue, or preserves into non-designated file type, likely causes significant data to leak standby.
For solving above weak point, the present invention, from backup procedure simplification, backup target generalization and backup high-level efficiency three aspects:, has formed a creationary invention just.

The present invention is achieved in that
A kind of real time backup method of processed-based name identification, concrete steps are as follows:
On the client of needs backup, backup application is installed, a filter Driver on FSD is installed simultaneously is used for the operation of monitoring file read-write, described backup application imports the backup template, template is named with apply names, comprises the temporary file type of the process name of monitoring and the process generation that needs are got rid of in template;
Further, described backup application will need the temporary file type transfer of the process generation that the process name information of monitoring and needs get rid of to filter Driver on FSD;
Further, described filter Driver on FSD is obtained the current process name that opens file opening in routine of file;
Further, when determine described process for the process that needs monitoring and this document be not this process need to get rid of file type the time, set up in Hash table at internal memory, the file object pointer of using is preserved the file complete trails as the crux code;
Further, the file of described filter Driver on FSD is write in routine and file rename routine and is checked whether the file object pointer exists in the internal memory Hash table, if be present in Hash table, take out the file complete trails from internal memory, be inserted in the listed files of needs backup, notify backup application to have new file to need backup by clobal simultaneously;
Further, after backup application obtains the event notice of filter Driver on FSD, need to obtain the listed files of backup from the control interface of filtration drive, read immediately on backstage by thread and need the file of backup to back up.
Preferably, the memory location of backup file can be in server, can be also in movable storage device.
Can find out from technique scheme, compared with prior art, the present invention can easily reach following purpose:
First, backup target of the present invention is selected simpler, the user only need to know that the data which program produces are to need backup, and then by selecting accordingly the template with the program name name, back-up application software just can the automated back-up process and got rid of simultaneously temporary file;
The second, the present invention is less to systematic influence, and system only need to be monitored the appointment process, does not need all process operation are monitored, and has reduced the impact on system running speed;
The 3rd, large scale deployment is more convenient, and in same unit, employee's vital document deposit position can be different according to personal habits, but the application software of using is generally identical, so more simple according to program deployment backup scenario;
The 4th, back up more comprehensively, the user only needs the option program name just can easily back up, so do not worry not backing up because save as Unknown file type or non-designated position in process.
In summary, the present invention at backup procedure easy to operate and backup target more reached unification aspect generalization two, more oversimplify when the user is operated and back up simultaneously high-level efficiency more, even without the user of any computer expertise also light Overall Backup file.
