Hard disk data protection method

Abstract

The invention discloses a hard disk data protection method. The method comprises the steps that three hard disks including the main hard disk, the first backup hard disk and the second backup disk are set; before data is stored in the main hard disk, the main hard disk is examined; if the main hard disk is in good condition, the data is stored in the main hard disk and automatically backed up in the first backup hard disk and the second backup hard disk at the same time; if the main hard disk is damaged, the data is stored in the first backup hard disk and automatically backed up in the second backup hard disk. Due to the setting of the double backup hard disks, on the basis of repeated periodic automatic examination, consistency and effectiveness of the data in each hard disk are ensured, so that the anti-loss capability of the data is improved, and the safety, stability and reliability of the data in the hard disks are improved.

Description

technical field [0001] The invention relates to a method for protecting hard disk data. Background technique [0002] With the advent of the era of big data and the rapid expansion of user groups, users have higher and higher requirements for data stability, reliability and security. At present, commonly used hard disks include mechanical hard disks and solid-state hard disks. Mechanical hard disks are prone to read and write errors due to the influence of temperature and vibration, and the inherent erasure and write times limit and bad block rate of solid-state hard disks can also cause read and write errors. Although the hard disk itself has an error correction function, it can only correct erroneous data with a small number of error bits through its own error correction algorithm, so its error correction capability is very limited. [0003] In the prior art, there are some relatively novel methods that can be used to protect data from being lost due to hard disk damage, ...

Problems solved by technology

[0003] In the prior art, there are some relatively novel methods that can be used to protect data and prevent it from being lost due to hard disk damage, but these methods are cumbersome to operate, have high requirements on the hard disk itself, and have high protection costs
