MySQL利用xtrabackup进行增量备份详细过程汇总_MySQL

1，创建mysql备份用户

mysql -uroot --password="" -e"CREATE USER 'backup'@'192.168.%' IDENTIFIED BY '123456'";

mysql -uroot --password="" -e"GRANT RELOAD, LOCK TABLES, REPLICATION CLIENT, CREATE TABLESPACE, SUPERON *.* TO 'backup'@'192.168.%'";

2，xtrabackup进行全量备份

备份命令：

xtrabackup --defaults-file=/etc/my.cnf--user=backup --password="123456" --port=3306 --backup--target-dir=/data/backups/mysql/full_incre_$(date +%Y%m%d)

PS: 2>/tmp/fullbackup.log 将备份信息放入文件中。

备份过程信息如下：

[root@data01 ~]# xtrabackup--defaults-file=/etc/my.cnf --user=backup --password="123456"--port=3306 --backup --target-dir=/data/backups/mysql/full_incre_$(date+%Y%m%d)

3，xtrabackup进行增量备份

3.1先录入一张表，实现第一次增量数据：

mysql> create table t4 select 'aaa' asa, 1 as b;
Query OK, 1 row affected (0.36 sec)
Records: 1 Duplicates: 0  Warnings: 0
 
mysql>
mysql> insert into t4 select 'bbb',2;
Query OK, 1 row affected (0.05 sec)
Records: 1 Duplicates: 0  Warnings: 0
 
mysql>

3.2 再进行增量备份1

xtrabackup --defaults-file=/etc/my.cnf--backup --user=backup --password="123456" --port=3306 --target-dir=/data/backups/mysql/incre_20150320/--incremental-basedir=/data/backups/mysql/full_incre_201503192>/tmp/incre_backup_1.log

3.3 再建立表2，实现第二天增量数据

建立一张表t_incre_2：

mysql> use test;
Database changed
mysql> create table t_incre_2 select'cc' as a,2 as b;
Query OK, 1 row affected (0.25 sec)
Records: 1 Duplicates: 0  Warnings: 0
 
mysql> insert into t_incre_2 select'dd',2;
Query OK, 1 row affected (0.05 sec)
Records: 1 Duplicates: 0  Warnings: 0
 
mysql> select * from t_incre_2;
+----+---+
| a | b |
+----+---+
| cc | 2 |
| dd | 2 |
+----+---+
2 rows in set (0.05 sec)
 
mysql>

3.4 进行第二天的增量备份

备份命令：

xtrabackup --defaults-file=/etc/my.cnf--backup --user=backup --password="123456" --port=3306 --target-dir=/data/backups/mysql/incre_20150321/--incremental-basedir=/data/backups/mysql/incre_20150320 2>/tmp/incre_backup_2.log

4，xtrabackup进行增量恢复

4.1为了验证比对，先删除两个增量备份前表里面的数据

mysql> delete from t4;
Query OK, 2 rows affected (0.05 sec)
 
mysql> delete from t_incre_2;
Query OK, 2 rows affected (0.04 sec)
 
mysql> select * from t4;
Empty set (0.00 sec)
 
mysql> select * from t_incre_2;
Empty set (0.00 sec)

4.2开始全备份恢复PREPARE THE BASE BACKUP

备份命令如下：

xtrabackup --defaults-file=/etc/my.cnf--prepare --user=backup --password="123456" --apply-log-only--target-dir=/data/backups/mysql/full_incre_20150319 2>/tmp/full_restore.log

4.5 恢复整个库

恢复命令：

xtrabackup --defaults-file=/etc/my.cnf--prepare --user=backup --password="123456"--target-dir=/data/backups/mysql/full_incre_20150319 2>/tmp/restore_end_3.log

停止mysql服务：

service mysqld5612 stop

开始rsync数据文件：

cd /data/backups/mysql/full_incre_20150319

rsync -rvt --exclude'xtrabackup_checkpoints' --exclude 'xtrabackup_logfile' ./ /home/data/mysql/data

授予mysql访问权限：

chown -R mysql:mysql /home/data/mysql/data

启动mysql服务：

service mysqld5612 start

4.6，验证

登录mysql，看到以前在备份之后删除的t4以及t_incre_2表的数据已经通过2次增量备份恢复过来了，如下所示：

mysql> select * from t4;
+-----+---+
| a  | b |
+-----+---+
| aaa | 1 |
| bbb | 2 |
+-----+---+
2 rows in set (0.05 sec)
 
mysql> select * from t_incre_2;
+----+---+
| a | b |
+----+---+
| cc | 2 |
| dd | 2 |
+----+---+
2 rows in set (0.06 sec)
 
mysql>

5，innobackupex先做全量备份

命令如下：

innobackupex --defaults-file=/etc/my.cnf--user=backup --password="123456" --host=192.168.52.129/data/backups/mysql/innobackupex_full_20150319/ --no-timestamp 2>/tmp/innobackupex_full.log

备份过程信息：

6，innobackupex做增量备份

6.1做第一次增量备份

先录入增量数据

mysql> create table incre1 select'incre1 table ' as incre1, 'a' as id;
Query OK, 1 row affected (0.06 sec)
Records: 1 Duplicates: 0  Warnings: 0
 
mysql> select * from incre1;
+---------------+----+
| incre1        | id |
+---------------+----+
| incre1 table  | a  |
+---------------+----+
1 row in set (0.00 sec)
 
mysql>

再进行增量备份，命令如下：

innobackupex --incremental/data/backups/mysql/innobackex_incre_1--incremental-basedir=/data/backups/mysql/innobackupex_full_20150319/--user=backup --password="123456" --host=192.168.52.129 --no-timestamp2>/tmp/innobackex_incre_1.log

7，innobackupex做增量恢复

7.1先删除两次增量数据，用来查看验证恢复结果

mysql> delete from incre1;
Query OK, 1 row affected (0.05 sec)
 
mysql> delete from incre2;
Query OK, 1 row affected (0.01 sec)
 
mysql> select * from incre1;
Empty set (0.00 sec)
 
mysql> select * from incre2;
Empty set (0.00 sec)

7.2 开始做恢复，恢复全备份

备份命令如下：

innobackupex --user=backup--password="123456" --host=192.168.52.129 --apply-log/data/backups/mysql/innobackupex_full_20150319/2>/tmp/innobackex_restore_full.log

备份过程信息如下：

......
