Abstract
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...

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...
