xtrabackup备份mysql数据库三：innobackupex测试一个全量和两个_MySQL

## 查看当前库中表的数据
(root@localhost) [test]>select count(*) from t_innodb;
+———-+
| count(*) |
+———-+
| 0 |
+———-+
1 row in set (0.00 sec)

## 执行插入数据操作，该操作在全备之后执行完成
(root@localhost) [test]>call addTest(100000,0);

## 执行全库备份
# 备份文件本文来源gaodai$ma#com搞$代*码*网夹：2014-06-19_20-53-41
# backup_type = full-backuped
# from_lsn = 0
# to_lsn = 3768612700
# last_lsn = 3788082769
# compact = 0
innobackupex –user=bkpuser –password=s3cret –defaults-file=/etc/my.cnf /backup

## 全备备份完成后，等待addTest 执行完成后，检查数据量
(root@localhost) [test]>select count(*) from t_innodb;
+———-+
| count(*) |
+———-+
| 100000 |
+———-+
1 row in set (0.03 sec)

## 再执行一个增量的备份
# 备份文件夹:2014-06-19_20-59-02
# backup_type = incremental
# from_lsn = 3768612700
# to_lsn = 3837968338
# last_lsn = 3837968338
# compact = 0
innobackupex –user=bkpuser –password=s3cret –defaults-file=/etc/my.cnf –incremental –incremental-basedir=/backup/2014-06-19_20-53-41 /backup

## 在库中新建一个表
CREATE TABLE `t_innodb_1` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`name` varchar(50) DEFAULT NULL,
`password` varchar(150) DEFAULT NULL,
`userstatus` int(2) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB;
Insert into t_innodb_1 select * from t_innodb where id<101;

(root@localhost) [test]>select count(*) from t_innodb_1;
+———-+
| count(*) |
+———-+
| 100 |
+———-+
1 row in set (0.00 sec)

## 再执行一个增量的备份
# 备份文件夹:2014-06-19_21-05-02
# backup_type = incrementall
# from_lsn = 3837968338
# to_lsn = 838021951
# last_lsn = 3838021951
# compact = 0
innobackupex –user=bkpuser –password=s3cret –defaults-file=/etc/my.cnf –incremental –incremental-basedir=/backup/2014-06-19_20-59-02 /backup

## 二次增量备份完成后，再次插入1000数据
(root@localhost) [test]>call addTest(1000,0);
Query OK, 1 row affected (0.32 sec)

(root@localhost) [test]>select count(*) from t_innodb;
+———-+
| count(*) |
+———-+
| 101000 |
+———-+
1 row in set (0.03 sec)

## 停止MySQL服务
[mysql@rhel5 data]$ /etc/init.d/mysql stop
Shutting down MySQL…. [ OK ]

## 移动之前的数据目录
[mysql@rhel5 data]$ mkdir ../bak
[mysql@rhel5 data]$ mv auto.cnf ib* mysql* p* test zabbix/ ../bak

## Prepare 全备,使用–redo-only
innobackupex –defaults-file=/etc/my.cnf –apply-log –redo-only /backup/2014-06-19_20-53-41/

## Prepare 第一个增量,使用–redo-only
innobackupex –defaults-file=/etc/my.cnf –apply-log –redo-only –incremental-dir=/backup/2014-06-19_20-59-02/ /backup/2014-06-19_20-53-41/

## Prepare 第二个增量,最后一个增量不需要–redo-only
innobackupex –defaults-file=/etc/my.cnf –apply-log –incremental-dir=/backup/2014-06-19_21-05-02/ /backup/2014-06-19_20-53-41/

## 针对完整备份，执行一次Restore
innobackupex –defaults-file=/etc/my.cnf –copy-back /backup/2014-06-19_20-53-41/

## 启动数据库，检查mysqld-error.log有无异常
[root@rhel5 ~]# /etc/init.d/mysql start
Starting MySQL. [确定]

## 登陆检查数据，发现正常
(root@localhost) [test]>select count(*) from t_innodb_1;
+———-+
| count(*) |
+———-+
| 100 |
+———-+
1 row in set (0.00 sec)

(root@localhost) [test]>select count(*) from t_innodb;
+———-+
| count(*) |
+———-+
| 100000 |
+———-+
1 row in set (0.00 sec)
