Backup method for data of mobile hard disk drive

Abstract

The invention relates to a backup method for data of a mobile hard disk drive. The backup method comprises the steps that the mobile hard disk drive is divided into a main storage area and a backup area; the backup area is hidden, and it is set that the backup area cannot be accessed by other programs based on file systems; when data is imported into the main storage area, the operation of checking an interface of the mobile hard disk drive, checking remaining capacity, checking and removing logic errors in the main storage area and the backup area and carrying out backup of the data into the backup area is carried out; when an error is found when data is read from the main storage area, repair operation is carried out on error data according to a preset algorithm; data obtained after recovery is compared with the corresponding data in the backup area; if a difference exists, the data obtained after recovery is deleted, and the corresponding data in the backup area is copied into the main storage area. According to the scheme, the consistency and effectiveness of the data in partitions are ensured by setting the backup area and combining multiple times of regular self-checking, so that the anti-losing capability of data is improved, and the safety, stability and reliability of the data in the mobile hard disk drive are improved.

Description

technical field [0001] The invention relates to a data backup method for a mobile hard disk. 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.
