(4)自动实现备份检验；
(5)还原速度快；
innobackupex --defaults-file=/etc/my.cnf --user=root -password='root' --database=root -socket=/var//mysql/mysql.sock /root/bakmysql
一直显示报错信息
innobackupex: Waiting for ibbackup (pid=1004) to suspend
innobackupex: Suspend file '/root/bakmysql/2015-12-01_17-06-01/xtrabackup_suspended_2'

innobackupex: got a fatal error with the following stacktrace: at /usr/bin/innobackupex line 2703

innobackupex: Error: The xtrabackup child process has died at /usr/bin/innobackupex line 2703.
原来发现库没安装
解决方法：yum install libgcc.i686
第二个报错还原时候出现
