Embodiment Construction

[0030] In order to have a better understanding of the technical solutions and beneficial effects of the present invention, the technical solutions of the present invention and the beneficial effects produced will be described in detail below with reference to the accompanying drawings.

[0031] After the file content is written, if there is a sudden power failure, instantaneous undervoltage, or system file damage, the file system will be in an inconsistent situation, which will easily cause the system files to be unable to read out and cause the system to fail to start normally. The main purpose of the power failure protection method provided by the present invention is to protect system files in the case of instantaneous undervoltage, system file damage or unexpected power failure. The invention adopts a joint mounting method to store the protection system files for execution when the system is idle, so as to solve this problem, and thereby play a more secure role in protecting t...

Abstract

The invention relates to a power-down protection method based on a universal computer operating system. The power-down protection method comprises the following steps: S1, acquiring an aufs file corresponding to an operating system version; S2, creating a folder to be downloaded; S3, adding the support of the kernel to aufs; S4, manufacturing initrd; and S5, generating a mirror image file initrd.img of the initrd. According to the power-down protection method based on the universal computer operating system, the data protection mode is flexible, system file safety is protected, and system fileprotection under the problems of instantaneous undervoltage, file system damage, accidental outage and the like can be achieved.

Description

Technical field [0001] The invention relates to the technical field of computer data security, in particular to a power-down protection method based on a general computer operating system. Background technique [0002] In recent years, due to its excellent performance and stability, the Linux system has received widespread attention and application in the computer industry. However, in the process of using it, it is inevitable to encounter unexpected power failures or file damage, which can lead to data loss and even It may cause the system to fail to start normally. In order to provide users with a complete Linux system, a power failure protection function is added in the design process, which also makes the role of power failure protection more and more important. [0003] The Linux platform hard disk data protection and recovery method (patent number CN 102495812 A) relates to the Linux platform hard disk data protection and recovery method. This method uses a hybrid mounting re...
