Problems solved by technology

[0005] However, in such a solution, the access control of the operating system itself cannot be used to solve such needs. For example, users need to install applications into the system.

Embodiment Construction

[0021] The present invention adopts following technical scheme:

[0022] 1. Write operation redirection technology based on hybrid file system.

[0023] 2. Based on read-only compression file system protection technology.

[0024] 3. The configuration technology of initializing the subsystem when the kernel starts based on Initrd.

[0025] 4. File system rapid detection and repair technology.

[0026] 5. Root file system detection technology based on file system identification.

[0027] Specifically:

[0028] 1. Prepare the root file system of the operating system, and install the operating system on the hard disk through the operating system installation program.

[0029] 2. Use the squashfs file system to package the prepared operating system root file system into an image file.

[0030] 3. The kernel adds support for file systems (such as ext4, etc.) used by aufs, squashfs, and storage devices, and recompiles the kernel in a built-in manner.

[0031] 4. Make the kerne...

Abstract

The invention discloses a hard disk data protection and recovery method of a Linux platform. The method implements protection and recovery for the data in a file system through a write operation redirection technology based on a hybrid file system, a protection technology based on a read-only compressed file system, an Initrd-based configuration technology for initializing a sub-system when a kernel moves later, a file system quick detection and repair technology and a root file system detection technology based on a file system identifier; and the method transparently protects the file system data of an operating system without using own file system access control of the operating system, records file modifications of the running process and recoveries the data as needed.

Description

technical field [0001] The invention relates to a method for protecting and restoring hard disk data based on aufs and squashfs on a Linux platform. Background technique [0002] Linux is a free and open source Unix-like operating system. There are many different Linuxes, but they all use the Linux kernel. Linux can be installed on a variety of computer hardware devices, from cell phones, tablets, routers and video game consoles, to desktop computers, mainframes and supercomputers. Linux is a leading operating system, and the 10 fastest supercomputers in the world all run the Linux operating system. [0003] Linux is recognized as an operating system with stable operation and high security, but server hardware failure and various unexpected factors will cause data loss on the Linux server hard disk. Especially for Linux servers used in the commercial field, data security, integrity and data recovery capabilities after disasters are the most concerned issues for every Linux...
