Abstract

The invention provides a parallel backup method, system and device for a database, and a medium. The method comprises the steps of receiving a backup instruction, wherein the backup instruction comprises a preset backup parallel number; determining an actual backup parallel number according to a comparison result between the preset backup parallel number and a numerical interval; and creating thecorresponding number of parallel processing units for receiving data blocks according to the actual backup parallel number so as to realize parallel backup. The method provided by the invention has the beneficial effects that remote backup of the database is realized through the parallel backup method; the length of the whole backup recovery window is effectively reduced; and the efficiency of database backup and the security of data backup are greatly improved.

Description

technical field [0001] The invention relates to the field of database backup, in particular to the field of database parallel backup. Background technique [0002] In the late 1960s, as computers began to be widely used in the field of data management, people put forward higher and higher requirements for data management technology, and thus a database management system that can manage and share data in a unified manner appeared. The wide application of databases will inevitably take into account data security issues, because databases often encounter various data loss situations such as man-made damage, disk damage, and natural disasters, so it is imperative to ensure data security. [0003] In order to ensure data security, general databases such as Dameng database have their own backup and recovery functions, but database backups often use a single-process or single-threaded processing method, resulting in a long backup and recovery window, which affects the backup effici...
