Method for intensively storing and backing up data based on operating system virtualization theory

Abstract

The invention relates to a method for intensively storing and backing up data based on an operating system virtualization theory in the technical field of computer application. The method is characterized by comprising the following steps of: constructing one to a plurality of virtual isolation environments on a host operating system of a physical host machine, wherein each virtual isolation environment has a use mode which is totally the same as the use mode of the host operating system; and completely isolating data produced in the virtual isolation environment from data produced by the host operating system, and storing the data to different physical storage positions respectively. By storing an application program relative to a working service of a user into the virtual isolation environment and running the application program, and redirecting the physical storage position to a storage server in a network through a common internet file system (CIFS) or internet small computer system interface (iSCSI) protocol, a manager only needs to back up the data on the storage server at a time when the data of all client hosts are needed to be backed up, so the working efficiency is improved greatly; meanwhile, only the data relative to the working service is backed up, so the backup storage space is saved and useless data restoration is avoided.

Description

technical field [0001] The invention relates to a method in the field of computer application technology, in particular to a data centralized storage and backup method based on the operating system virtualization principle. Background technique [0002] With the vigorous development of informatization in our country, the application of electronic data is becoming more and more extensive. While greatly improving production efficiency, electronic data has increasingly become an important asset for all walks of life and even the general public. The confidentiality, integrity and availability of electronic data are gradually related to national security, core competitiveness of enterprises, and personal assets. Therefore, the issue of data security—that is, the prevention of data leakage, loss, and abuse—has become a hot issue in the field of information security and has attracted more and more attention. In all branches of data security, the problem of data loss prevention has...

First of all, the mechanism’s criteria for judging work files are relatively mechanical, and cannot distinguish whether the changed files have backup value. That is to say, when the user is working, all changed files will be backed up to the server, which will cause A large number of invalid files—such as...
