恢复误删除表黑科技之relay log大法（续）
Preface
I've stuck twice in my previous experiments in backing up dropped tables.I am still not sure that why I got failure yesterday.Therefore,I decide to do that again with the same steps on another environment.Let's see the details.
Procedure
1. All the operations on master zlm1.
//Check data at first.
