Problems solved by technology

Currently, traditional Linux file backup tools such as tar and cpio have relatively simple functions and are difficult to handle data backup at the file system level. Only snapshot technology based on BTRFS and ZFS file systems and logical volume management ( LVM) snapshot technology
The default ext3 or ext4 file system of Linux does not support snapshots, and logical volume management needs to be installed, and many Linux users may not have partitioned and created 1vm logical volumes. Therefore, for ordinary users, the function of snapshots is very useful. large limitations of use

Embodiment Construction

[0021] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings. This embodiment is carried out on the premise of the technical solution of the present invention, and the detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following examples.

[0022] First, the user tells the management module the files or directories to be monitored through the application module according to the backup needs, and when monitoring is required, the application module sends a command to the management module to start monitoring. Similarly, when monitoring is not required, the application module sends a command to stop monitoring to the management module. For example, the user backs up the files between 10:00 and 11:00, so the user can choose to monitor the files at or before 10:00, and when the backup is over, the user can end the monitorin...

Abstract

The invention discloses a method for obtaining a consistent backup on a Linux platform. The method comprises the steps that files to be backed up are monitored, write operations of the files are intercepted in the backup process of the files, real-time data files of the files in the process of the write operations are obtained, mirror image data of the monitored files and real-time data of the monitored files are combined to form a backup according to the time sequence, and the backup generated at the moment is the consistent backup. According to the method for obtaining the consistent backup on the Linux platform, the requirement for a Linux operating system is low; due to the fact that an application module and a kernel module are used, the consistent backup of files or databases can be obtained on any Linux operating system, and the method for obtaining the consistent backup on the Linux platform is universal, and does not depend on any selectable configuration or technologies.

Description

technical field [0001] The invention relates to the field of computer data security, in particular to a method for obtaining consistent backup on the LINUX platform. Background technique [0002] With the wide application of computer systems and the Internet in various fields, many government agencies, companies and even individuals are increasingly dependent on computer data, so data security has become one of the important demands of the information society, and data backup is the core of data security question. [0003] This technical solution solves exactly how to obtain a consistent backup on the Linux platform. When the user makes a backup in a certain state, there may be an application that is modifying a certain file or data. After the backup, the file is in another state, and it is almost impossible to restore the database data in this state. [0004] Linux is an operating system with stable performance, powerful functions and high efficiency. Currently, traditio...
