1.使用mydumper工具全庫備份。 1)源碼編譯安裝 2)全庫備份 2.誤操作truncate table gyj_t1;利用mysqldump的備份和binlog日誌對表gyj_t1做完全恢復。 如下場景： create table gyj_t1(id int,name varchar(10)); insert into gyj_t1 values(1,‘AAAAA‘); commit; mysqldump全庫備份。。。 insert into gyj_t1 values(2,‘BBBBBB‘); commit; truncate table gyj; 開始恢復。。。 恢復完成！！！ 驗證：select * from gyj_t1;有2條記錄 3.誤操作MySQL數據庫：rm /u01/my3306/data/*;利用Innobackupex的備份和binlog日誌對MySQL數據庫做完全恢復。 如下場景： create table gyj_t2(id int,name varchar(10)); insert into gyj_t1 values(1,‘AAAAA‘); insert into gyj_t1 values(2,‘BBBBBB‘); commit; select * from gyj_t2; #（2條記） 使用Innobackupex備份全庫 insert into gyj_t1 values(3,‘CCCCC‘); commit; select * from gyj_t2; #（3條記) 誤操作：rm –rf /u01/my3306/data/* 開始恢復。。。 恢復完成！！！ 驗證：select * from gyj_t3;有3條記錄
1.使用mydumper工具全庫備份。
