 MySQL Point in Time Recovery: How To Configure And How Does it Work? The point-in-time recovery allows you to restore a MySQL database to a specific time in the past. The point-in-time recovery relies on two key components: Full backup: This serves as the foundation for recovery, providing the starting state of the database. Binary logs: These binary log files record all changes made to the database, allowing you to replay those changes to a desired point. If you don’t have a full backup or binary logs enabled, you cannot carry the point-in-time recovery. We’ll illustrate how to perform the point-in-time recovery in MySQL to recover a database to a specific point in time. Checking binar log status:- We need login to mysql server and run given below command:- show global variables like 'log_bin' ; Show output for enable mysql-bin log.
