我的Mysql是5.6版本，通过自己下载的rpm包执行安装：
yum instal percona-xtrabackup-2.1.7-721.rhel6.x86_64.rpm
会出现如下的安装错误提示：

原因是我安装的是5.6版本，而这个的依赖却是需要用5.1的，故会冲突，可以用percona官网的源可以避免此冲突：
操作方法如下：

执行完此操作后可用yum list | grep backup查看当前相关的备份工具
[root@host2 MySQL]# yum list | grep backup percona-xtrabackup.x86_64 2.2.11-1.el6 @percona percona-xtrabackup-20.x86_64 2.0.8-587.rhel6 percona percona-xtrabackup-20-debuginfo.x86_64 2.0.8-587.rhel6 percona percona-xtrabackup-20-test.x86_64 2.0.8-587.rhel6 percona percona-xtrabackup-21.x86_64 2.1.9-746.rhel6 percona percona-xtrabackup-21-debuginfo.x86_64 2.1.9-746.rhel6 percona percona-xtrabackup-debuginfo.x86_64 2.2.11-1.el6 percona percona-xtrabackup-test.x86_64 2.2.11-1.el6 percona percona-xtrabackup-test-21.x86_64 2.1.9-746.rhel6 percona
最后执行：
yum install percona-xtrabackup
就可以顺利安装了。
安装percona-xtrabackup一直提示依赖冲突的一个解决办法
