XtraBackup中主要包含了三个工具
xtrabackup：支持innodb存储引擎表，xtradb存储引擎表
innobackupex：支持innodb存储引擎表、xtradb存储引擎表、myisam存储引擎表。
xbstream：流备份工具，用于减少备份和传输过程中的IO

[root@timesten mysqlbin]# cat /etc/my.cnf

basedir = /opt/mysql
datadir = /opt/mysql/data
port = 3306
server_id = 1
socket = /var/lib/mysql/mysql.sock


[root@timesten mysqlbin]#


数据库的完整备份
innobackupex --defaults-file=/etc/my.cnf --user=root --password='oracle'  /tmp/mysql

InnoDB备份，使备份可用
innobackupex --apply-log  /tmp/mysql/2015-07-10_15-03-38   （步骤一备份完成后会产生2015-06-15_14-57-24目录）
