In this post I will share a scenario of a MySQL database restore from the binary logs.
Recently someone accidentally dropped an important MySQL database and the backup was not present!
As we know the the binary log contains DMLs to table data and that’s where our hope lies. Luckily the binary log retention period (expire_logs_days) was set to 30 days and the CREATE DATABASE was still present in the binary logs.
Thus this restore of the dropped MySQL database can be done from extracting respective DMLs point-in-time. Here we will play the binary logs against a temporary MySQL instance and extract the required database.
