Problems solved by technology

The total bandwidth of data recovery can be determined by determining the target recovery speed of each target disk, and the cluster recovery speed can be controlled according to the size of the cluster. For clusters of different sizes, the total bandwidth of data recovery can be set reasonably, which can ensure While completing data recovery normally, it can avoid performance waste or pressure on the front end, and better meet the needs of users

Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. 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.

[0038] The core of the present invention is to provide a data recovery method, device, equipment and medium. The total bandwidth of data recovery can be determined by determining the target recovery speed of each target disk, and the cluster recovery speed can be controlled according to the size of the cluster. For clusters of different sizes, the total bandwidth of data recovery can be set reasonably, which can ensure While completing data rec...

Abstract

The invention discloses a data recovery method. The method comprises the steps: determining the number of target disks used for completing data recovery; determining a total bandwidth of data recoveryaccording to the number and a preset target recovery speed of the target disk; and according to the total bandwidth, setting an actual recovery speed of the target disk to enable the target disk to perform data recovery according to the actual recovery speed. Therefore, according to the invention, the total bandwidth of the recovered data can be reasonably set for the clusters of different scales, so that the performance waste or the pressure on the front end can be avoided while the data recovery is normally completed, and the requirements of users can be better met. In addition, the invention provides a data recovery device, equipment and a medium corresponding to the method.

Description

technical field [0001] The present invention relates to the technical field of distributed data storage, in particular to a data recovery method, device, equipment and medium. Background technique [0002] With the rapid development of distributed data storage technology, distributed systems have been widely used. The distributed storage system converts the files to be stored into storage objects and stores them in disks, and each disk is managed by a daemon process. Data recovery is a commonly used technology in distributed systems, and it is usually used in the following two scenarios; the first is that there is a faulty disk in a node of the cluster, and the redundant data on other disks needs to be restored to a non-standard disk that meets the requirements through data recovery technology. The second is that when the cluster expands or shrinks, it is necessary to use data recovery technology to enable objects to migrate flexibly to achieve a balanced distribution of da...
