Abstract

The invention discloses a dual-active disaster recovery method and device and electronic equipment, and is applied to a first server, the method comprises the following steps: obtaining a file operation request corresponding to a target file; when the file operation request is an update type operation request, packaging the update type operation request into an update message; and sending an update message to the message queue, so that the second server executes the file operation request on the target file based on the update message in the message queue. Under the condition of ensuring the read-write performance of the distributed file system, the remote disaster recovery effect can be realized, the data security of the distributed file system can be improved, and the distributed file system can still be used normally and the data cannot be damaged and lost under the condition that a certain data center is damaged.

Description

technical field [0001] The invention relates to the technical field of cloud database cluster systems, and in particular to a dual-active disaster recovery method and device, and electronic equipment. Background technique [0002] Distributed file system is one of the typical storage systems in the era of big data. Based on distributed technology, the server connects multiple servers through the network to form a cluster system, fully utilizes the storage capacity of multiple servers, and provides users with unified The distributed file system provides users with the ability to store massive files. Existing distributed file systems generally ensure data security through the copy mechanism of data blocks. The copy mechanism of the data block is to save multiple copies for each data block of the file in the system. In the distributed file system, the copy storage strategy of data blocks generally disperses the copies in the same data center, because the copies are scattered ...
