mysqldump当数据量很大的时候，不建议使用此工具，应当采用的是oracle公司提供了针对企业的备份软件Mysql Enterprise Backup简称mysqlbackup
一、安装
[[email protected] bjia]# unzip p19957495_3110_Linux-x86-64.zip [[email protected] bjia]# tar zxvf meb-3.11.1-linux-glibc2.5-x86-64bit.tar.gz [[email protected] meb-3.11.1-linux-glibc2.5-x86-64bit]# cd meb-3.11.1-linux-glibc2.5-x86-64bit [[email protected] meb-3.11.1-linux-glibc2.5-x86-64bit]# cd bin [[email protected] bin]# cp mysqlbackup /usr/bin/ 至此Mysqlbackup工具已经安装完成
二、全量备份

备份完毕，务必要对data目录授权，否则没有权限操作读写数据库。
[[email protected] 3003]# chown -R mysql.mysql /9tong/mysql/data/3003/*
重启一下数据库，否则无法读取表的结构，这个也是非常重要的 [[email protected] 3003]#mysqladmin -u root -S /tmp/mysql3003 shutdown [[email protected] 3003]#mysqld_multi start 1-2 Copyright (c) 2000, 2011, Oracle and/or its affiliates.

4、验证增量备份是否正常
mysql> desc user_account2016 ; +--------------+---------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +--------------+---------------+------+-----+---------+-------+ | id | int(11) | NO | | 0 | | | uid | int(11) | NO | | 0 | | | account | varchar(50) | NO | | | | | pswd | varchar(45) | NO | | | | | realName | varchar(50) | NO | | | | | verifyCode | decimal(10,0) | NO | | 0 | | | verifyTimes | decimal(1,0) | NO | | 0 | | | registerTime | decimal(16,0) | NO | | 0 | | | activeTime | decimal(16,0) | NO | | 0 | | | lastActive | decimal(16,0) | NO | | 0 | | +--------------+---------------+------+-----+---------+-------+ 10 rows in set (0.00 sec) 正常显示，增量备份成功完成。
注：1、首先检查匹配释放全备事物日志文件（当然如果备份中使用了backup-and-apply-log在备份的时候已经检测匹配了，就不需要这一步了。由于做全量备份的时候已经匹配了，故第一步操作可以省去）
2、第一次增量备份的文件释放到全备文件里面（首先会进入事物日志，然后是表空间），所以--backup-dir指向全备目录（基于LSN点向后增量）
5、第二次增量备份
1、做之前先操作以下文件 mysql> drop table user_active_60 ; Query OK, 0 rows affected (0.12 sec) mysql> drop table user_active_15; Query OK, 0 rows affected (0.04 sec) mysql> drop table user_active_30; Query OK, 0 rows affected (0.07 sec) 2、第二次备份操作 [[email protected] meta]# mysqlbackup --backup-dir=/root/2015-06-02_12-20-00/ --incremental-backup-dir=/root/2015-06-02_13-17-52/ apply-incremental-backup MySQL Enterprise Backup version 3.11.1 Linux-2.6.18-194.el5-x86_64 [2014/11/04] Copyright (c) 2003, 2014, Oracle and/or its affiliates.

结论：增量备份导入所花费的时间和全量差不多，而且增量的越多，细节处理也越多。因此建议是全量做一次，增量少做。切记导入数据还原后。注意权限的修改，及重启数据库生效。
