A method for file backup based on process identification file

Abstract

The invention provides a method for file backup based on a process identification file. The method includes the steps: setting a process name or file suffix to be backed up by a policy management tool module to form policy information; transmitting an IRP (I / O request packet) to a file filter driver module by an I / O manager when performing write operation or save operation on the file by application software, determining whether to perform the write operation or save operation on the file or not by a process according to the received IRP by the file filter driver module, judging whether to back up the file or not according to the policy information, and informing a terminal of backing up the file when the file needs to be backed up; informing a corresponding file server of a new backup file needing to be extracted and saved in the file server by the terminal after the file is locally backed up in the terminal, and extracting and saving the corresponding backup file by the terminal. By the method, the file with a certain process or type can be backed up, and local backup can be effectively executed when a client side is disconnected from a server side, so that the pressure of the server is reduced.

Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to a method for backing up files based on process identification files. Background technique [0002] Most enterprises have the problem of damage or loss of electronic documents due to intentional or unintentional mistakes of employees, which brings incalculable losses to the enterprise. File backup can ensure that lost files can be restored in time in the event of a disaster of file damage or loss. . The existing technical solutions are all based on the file backup method of the server / client mode. When the client starts, it connects to the server and maintains smooth communication with the server. The operator of the client makes the local file and the remote backup file by uploading and downloading files. Synchronization, the backup files are uniformly stored in a certain space on the server side, and the operator of the client side can perform "upload to server b...

AI Technical Summary

Problems solved by technology

[0003] Yet the scheme of prior art has following defect: 1, passive backup, promptly backup must be manually operated by the operator of client, if operator does not back up in time, just in case file damage or loss just can't find the newest backup version, file can't be recovered

Unable to effectively prevent accidental loss of data;

[0004] 2. Files cannot be backed up based on processes and file suffixes, and there may be omissions during backup, that is, some files may not be backed up in time due to operator omissions;

[0005] 3. If there are too many clients controlled by the server, backing up all files may result in a huge number of backup files stored on the server;

[0006] 4. If the client cannot connect to the server, the file backup program of the client basically cannot work;

[0007] 5. In some extreme products, in order to ensure that the client file is consistent with the server file or that only one client can edit the file, if the client cannot connect to the server, the local file will be locked and cannot be edited;

[0008] 6. Conflicts between local files and server files often occur;

[0009] 7. It often happens that the local file and the server file cannot be uploaded or downloaded due to inconsistent fingerprints
