I would have a kind of table that lists the versions of Percona xtrabackup compatible with their systems and versions of MySQL. Does someone could point me to a link or document?
For example, xtrabackup compatible with MySQL 5.6.26 and RHEL5, the latest version please.
“It can back up data from InnoDB, XtraDB, and MyISAM tables on MySQL 5.1 , 5.5, 5.6 and 5.7 servers, as well as Percona Server with XtraDB. For a high-level overview of many of its advanced features, including a feature comparison, please see About Percona XtraBackup.”
CentOS 5 and RHEL 5
CentOS 6 and RHEL 6 (Current Stable) 
CentOS 7 and RHEL 7
Amazon Linux AMI (works the same as CentOS 6)"
