A data backup method and related equipment and system

Abstract

Disclosed are a data backup method and a related device and system. The data backup method provided in this embodiment involves receiving a backup indication for triggering a backup policy sent from a backup server through a main storage device, then processing through a snapshot technology, and sending backed up data to the backup server and a backup storage device. No application server is involved in a backup process, preventing the service performance of an application server from being affected as a result of the application server operating client backup software or disk mirroring functional software to back up data, realizing the function of backing up data efficiently while the application server is operating normally, i.e., the data backup function and the operation of service software by the application server not interfering with each other.

Description

technical field

[0001] The present application relates to the technical field of data backup, in particular to a data backup method and related equipment and systems. Background technique

[0002] At present, due to the surge in data volume, the huge storage performance of databases, and the richness of device application functions, data security issues are particularly important. Therefore, various backup technologies and backup methods derived from various backup technologies are becoming more and more important to data protection. The degree of awareness of sexuality is deepening and developing rapidly.

[0003] Data backup technology refers to the process of copying all or part of the data set from the hard disk or array of the application host to other storage media in order to prevent data loss caused by system operation errors or system failures. Traditional host-based backup usually runs the disk mirroring function software in the application server, and when sendin...

Examples

Embodiment Construction

[0192] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0193] In the following, specific examples will be used to describe in detail respectively.

[0194] The first embodiment of the present application provides a data backup method, which is mainly based on data block backup. In the shared storage architecture, the data of the application server is stored on the underlying main storage device. In order to ensure the data reliability of the server, usually It is necessary to back up the data stored in the underlying primary storage dev...
