A distributed storage method, device, computer equipment and storage medium

Abstract

The embodiment of the present invention discloses a distributed storage method, device, computer equipment, and storage medium. The method includes: grouping files to be stored to form multiple data groups; grouping all data into at least three data fragments, Wherein, each data fragment includes some data packets, and each data packet is added to at least two data fragments; each data fragment is stored in a distributed storage node; record data fragments and data The corresponding relationship between groups, and the corresponding relationship between storage nodes and stored data fragments; delete the local files to be stored. The technical solution of the embodiment of the present invention facilitates users to store files in a distributed network to reduce storage costs, and can effectively improve the privacy and security of stored files, thereby preventing attackers from restoring original files.

Description

technical field

[0001] The embodiments of the present invention relate to the technical field of data storage, and in particular, to a distributed storage method, device, computer equipment, and storage medium. Background technique

[0002] The cloud storage technology in the prior art is generally stored through a centralized server. With more and more stored data, the server storage space and bandwidth resources are seriously occupied, and the cost of cloud storage continues to increase. Moreover, the existing cloud storage technology stores data in the cloud without encryption, and the privacy of the data is endorsed by the credit of large cloud storage service providers.

[0003] If distributed storage technology is adopted, due to the decentralized storage of data, the credit will be decentralized, which will lead to the problem of insecure data storage caused by unstable storage nodes, which are easy to lose and vulnerable to attack.
