用xtrabackup进行数据备份恢复时出现如下问题：

option_ibbackup_binary is autodetect, trying to connect to MySQL

Connected to MySQL with pid 6358

Failed to connect to MySQL server to detect version.

You must set xtrabackup version to use with --ibbackup option.

Possible values are xtrabackup_51 (for MySQL 5.0 and 5.1) or xtrabackup (for MySQL 5.1 with InnoDB plugin or Percona Server)

原因：

  Xtrabackup是一个对InnoDB做数据备份的工具

解决：

1. 使用其它备份方式。如mysqldump

2. 修改数据库引擎。。。（推荐），，尽量使用InnoDB引擎。

查看数据引擎：

show crate table table_test;

修改数据引擎：

alter table table_name engine=innodb;
