基于Xtrabackup备份集来恢复某个误删除的表（drop）

 

Preface

 

    Yesterday,I've demonstratated how to rescue a droped and a truncated table based on mysqldump backup.Let's see what's different in rescuing them based on a backup set made by Xtrabackup.Binlog is also indispensable,if we want to rerieve all the incremental data of them.

 

Framework

 

Hostname	IP/Port	Identity	OS Version	MySQL Version	GTID Mode	Binlog Format
zlm2	192.168.1.101/3306	master	CentOS 7.0	5.7.21	on	row
zlm3	192.168.1.102/3306	slave	CentOS 7.0	5.7.21	on	row

 

Precedure

 

Step 1: Destroy the table.

 

Generate a backup with Xtrabackup first.

Step 2: Begin to restore backup set.

 

Copy the backup set to another server(mine is zlm3) with newly initialized instance of MySQL.

    Okay,I didn't get my supposed consequences in the above test this time.In my opinion,the miss dropped table "sbtest7" should have been recovered to the state of "9990" instead of "10000" what really astonished me.

    The transaction of deleting 10 records befor dropping "sbtest7" ,together with those other transactions in mysql-bin.000035,was rolled back.Even if the slave had executed the newest GTID "uuid:3720222",the incremtental modifications on the table couldn't be rescued.

    I guess the result is due to that the redo log files in backup set didn't contain the transactions information,thus,it chose to roll back the transactions.
