Abstract

The invention relates to the technical field of data recovery, and provides a data recovery method and device, a storage medium and computer equipment. The data recovery method comprises the following steps: when any data node in the distributed network runs, regularly checking whether the total copy amount of each piece of single data stored in the data node in the distributed network is M or not; if yes, indicating that the total number of copies of each piece of single data stored in the system is M, and the check is ended; and if not, applying for establishing a new data node in the distributed network for the single-piece data with the total copy amount less than M, and diffusing the single-piece data to the corresponding newly-established data node, so that the total copy amount of the single-piece data stored in the distributed network is M. According to the embodiment of the invention, the lost single-chip data can be recovered in a diffusion and backup mode through the regular check of the online data nodes of the distributed network.

Description

technical field [0001] The invention relates to the technical field of data recovery, in particular to a data recovery method, device, storage medium and computer equipment. Background technique [0002] In a distributed network, the nodes that store data, because the hardware devices that carry the nodes, due to various network factors and the service life of the hardware itself, some nodes will be abnormally offline, which will cause the data stored on it to be lost. Therefore, how to ensure the entire The integrity of network data has become an urgent problem to be solved. Contents of the invention [0003] The invention provides a data recovery method, device, storage medium and computer equipment, through the regular inspection of the online data nodes of the distributed network itself, and recovering the lost single-chip data in the way of diffusion and backup. [0004] In order to solve the above problems, the present invention adopts the following technical soluti...
