MySQL利用xtrabackup进行增量备份详细过程汇总_MySQL
备份
过程
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：

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

4.5 恢复整个库
恢复命令：

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>

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
