Recently, you updated the xtrabackup versions from 2.0 to 2.1.x in the yum repo. This leads to the problem, that xtrabackup does not work with CentOS 6 default MySQL 5.1.69: 130918 14:09:01 innobackupex: Connecting to MySQL server with DSN ‘dbi:mysql:;mysql\_read\_default\_group=xtrabackup’ as ‘xxx’ (using password: YES). 130918 14:09:01 innobackupex: Connected to MySQL server innobackupex: Error: Support for MySQL 5.1 with builtin InnoDB (not the plugin) was removed in Percona XtraBackup 2.1. The last version to support MySQL 5.1 with builtin InnoDB was Percona XtraBackup 2.0. at /usr/bin/innobackupex line 389. Repo Path in the repo file is [http://repo.percona.com/centos/$releasever/os/$basearch/](http://repo.percona.com/centos/%24releasever/os/%24basearch/) so I assume the tools there work with CentOS6 (x86\_64), but xtrabackup does not… Is this a bug? ---

Found it. There is a percona-xtrabackup-20 package available. My repo file was holding an “includepkgs=percona-xtrabackup”, therefore I didn’t see it.
