Abstract

The embodiment of the invention discloses a data recovery method and system, electronic equipment and a computer storage medium. The data recovery method comprises the steps of importing existing backup data; determining a main library log increment between the backup time point of the existing backup data and the selected data recovery time point; analyzing the main library log increment, and determining an event identifier corresponding to a data recovery time point; converting the master library log into a slave library log; according to the event identifier, executing copying of the corresponding slave library log to complete data recovery; and converting the master library log into a slave library log with the same internal format (relaylog). Because the relaylog file can be directlyidentified and read by the mysql database, the relaylog file can be directly identified and read by the mysql database. Therefore, a series of defects caused by the fact that the binlog file needs tobe additionally analyzed can be effectively overcome, the efficiency and the success rate are improved, and breakpoint recovery is supported, and the data recovery progress can be manually controlled,and the data recovery speed is increased.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data recovery method, system, electronic equipment and computer storage medium. Background technique [0002] With the continuous advancement of electronic information technology, the amount of data generated in the process of business applications is also increasing. Databases for managing and recording data began to be widely used. Among them, the Mysql database is a very commonly used relational open source database system. [0003] In daily business application scenarios, wrong deletion of database data due to various factors occurs from time to time. If the data cannot be restored in a timely and effective manner, it will have a very serious impact and loss on the normal operation of the business. [0004] The existing Mysql database data recovery mechanism is based on backup data, by parsing the main library log (binlog) file, and copying and executing the cor...
