innobackupex: Error: Failed to connect to MySQL server as DBD::mysql module is not installed at ./innobackupex line 2976.
Have you install/upgrade xtrabackup with tarball? because if you have installed through yum/apt then it should install necessary libs to satisfy dependencies.
Can you try to install DBD::mysql with either “yum install perl-DBD-MySQL” OR with CPAN and check?
I have the same issue :
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.
I have : percona-xtrabackup x86_64 2.1.8-733.rhel6 version install from the repository and mysql server 5.1.73.
