Abstract

The invention discloses a data disaster tolerance system, method and device. One specific embodiment of the method comprises the steps that a to-be-stored file is received; to-be-stored data in the to-be-stored file is coded, and a first verification file is obtained; a first coding file of the to-be-stored file is segmented to obtain at least two first coding file segments, wherein the first coding file comprises the to-be-stored file and the first verification file, and each first coding file segment comprises the to-be-stored data in the to-be-stored file and first verification data in thefirst verification file; and the obtained first coding file segments are sent to at least one first data storage terminal. Through the embodiment, storage space for data disaster tolerance is reduced.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of Internet technology, especially to a data disaster recovery method and device. Background technique [0002] Data disaster recovery is to ensure the security of data when the computer system suffers from natural disasters or man-made disasters. [0003] However, the existing data disaster recovery methods usually adopt multi-copy disaster recovery technology, and store multiple copies of a data file on different electronic devices. As far as the commonly used three-copy backup is concerned, the occupied storage space It is three times the size of the original data file, which directly increases the hardware storage cost of the disaster recovery, thus, there is a problem of occupying too much storage space. Contents of the invention [0004] The purpose of this application is to propose an improved data disaster recovery system, method and device to sol...
