Hard disk data backup method

Abstract

This case discloses a method for backing up data on a hard disk, including: partitioning a single hard disk and setting them as the main storage area, the first backup area, and the second backup area respectively; before storing data, check the main storage area: if If the main storage area is intact, the data will be stored in the main storage area, and automatic backup will be performed in the first backup area and the second backup area at the same time; if the main storage area is damaged, the data will be stored in the first backup area, and at the same time The second backup area is automatically backed up. In this case, a double backup area is set in a single hard disk, combined with multiple regular self-inspections to ensure the consistency and validity of data in each area, thereby improving the ability to prevent data loss and increasing the security of data in the hard disk. Security, Stability and Reliability.

Description

technical field [0001] The invention relates to a backup method of 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.

Problems solved by technology

[0003] In the prior art, there are some relatively novel methods that can be used to protect and back up data to 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
