Xtrabackup是一个对InnoDB存储引擎做数据备份的工具,支持在线热备份(备份时不影响数据读写),是商业备份工具InnoDB
Hotbackup的一个很好的替代品.Xtrabackup有两个主要工具:xtrabackup,innobackupex,且只能备份InnoDB和XtraDB两种存储引擎的表,而不能备份MyISAM数据表
1.下载安装xtrabackup工具
[root@tong2 ~]# wget
[root@tong2 ~]# tar xvf Percona-XtraBackup-2.2.7-r5050-el6-x86_64-bundle.tar
[root@tong2 ~]# ll percona-xtrabackup-*

[root@tong2 ~]# rpm -ql percona-xtrabackup-2.2.7-5050.el6.x86_64
/usr/bin/innobackupex

2.创建数据库和innodb表
[root@tong2 ~]# mysql -u root -p

3.完整备份innodb存储引擎的表
[root@tong2 ~]# innobackupex –help |more–查看帮助信息
[root@tong2 ~]# innobackupex –user=root –password=system /opt/tong 2> /opt/tong/backup.log
[root@tong2 ~]# ll /opt/tong/-01-04_16-00-37/
total 12324

[root@tong2 ~]# ll /opt/tong/-01-04_16-02-36/

[root@tong2 ~]#
4.在完整备份中添加增量备份
[root@tong2 ~]# innobackupex –user=root –password=system –incremental –incremental-basedir=/opt/tong/-01-04_17-34-25/ /opt/tong
–incremental–增量备份
–incremental-basedir –完整备份文件的路径
/opt/tong–增量备份文件存放处
5.全备份时压缩以节省资源
