Embodiment Construction

[0070] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0071] When using RAID to store data, the data to be written is stored in a designated hard disk, and a hard disk is randomly selected from other hard disks other than the designated hard disk to back up the data to be written. However, the inventor found in research that, with the above-mentioned data storage method, the data on one hard disk may be backed up to multiple hard disks, which is inconvenient for data management.

[0072] For example, when storing...

Abstract

Embodiments of the invention provide a data storage method and device, electronic equipment and a storage medium. The data storage method comprises the steps of obtaining configuration information ofeach hard disk; determining a hard disk group of each hard disk according to the configuration information of each hard disk and a preset grouping condition, each hard disk group comprising a main storage hard disk and a redundant hard disk; and selecting one hard disk group as a target hard disk group, writing to-be-written data into the main storage hard disk of the target hard disk group, and performing redundant backup on the to-be-written data in the redundant hard disk of the target hard disk group. According to the data storage method provided by the embodiment of the invention, the hard disks are grouped, and the data in the main storage hard disk and the redundant hard disks in the same hard disk group is the same, so that data management can be facilitated.

Description

technical field [0001] The present invention relates to the technical field of data storage, in particular to a data storage method, device, electronic equipment and storage medium. Background technique [0002] RAID (Redundant Arrays of Independent Disks) is a technology that combines multiple independent physical hard disks in different ways to form a logical disk, thereby providing higher storage performance and data redundancy than a single hard disk. [0003] When using RAID to store data, the data to be written will be stored in the designated hard disk. At the same time, in order to increase data security, a hard disk will be randomly selected from other hard disks other than the designated hard disk to back up the data to be written, and the data to be written will be recorded. The backup location of written data for later reading. [0004] However, the above-mentioned data storage method is inconvenient for data management after each hard disk is disassembled and s...
