由于之前服务器安装的xtrabackup比较老的版本，不支持mysql 5.7的热备，需要升级下版本或新服务器部署2.4.版本。这里我们官网https://www.percona.com/downloads/XtraBackup/  下载最新版

安装方法:

Ubuntu环境下安装 ：

1，单独安装deb包：

1，下载： wget https://www.percona.com/downloads/XtraBackup/Percona-XtraBackup-2.4.4/\ binary/debian/jessie/x86_64/percona-xtrabackup-24_2.4.4-1.jessie_amd64.deb

2，安装

$ sudo dpkg -i percona-xtrabackup-24_2.4.4-1.jessie_amd64.deb

注意：

当这样手动安装软件包时，您需要确保解决所有的依赖关系并自己安装缺少的软件包。

2，通过仓库安装
