Abstract

The embodiment of the invention discloses a RBD data storage method and system based on Ceph, a server and a storage medium. The method comprises the following steps: acquiring RBD block data; splitting the RBD block data according to a first sequence to obtain a plurality of RBD sub-data; and storing the plurality of RBD sub-data into at least one storage pool according to a second sequence. By providing safety protection for the RBD equipment in the Ceph distributed cluster file system, the technical effects that when the distributed cluster file system breaks down, data cannot be lost, andthe data can be recovered in time are achieved.

Description

technical field [0001] The embodiment of the present invention relates to data backup and recovery technology, and in particular to a Ceph-based RBD data storage method, system, server and storage medium. Background technique [0002] With the development of cluster storage technology, the distribution of the cluster file system is particularly important to the scalability of the cluster. Since most cluster file systems are implemented by means of central nodes and metadata servers. Its defect is that the expansion of the cluster file system is limited by the central node and the metadata server. Based on this background, Ceph is a better choice. Ceph is a unified, distributed storage system designed for excellent performance, reliability, and scalability. Specifically, "unified" means that Ceph can provide three functions of object storage, block storage and file system storage at the same time in one storage system to meet different application requirements. Block stor...
