Warning
In order to sucessfully install Percona XtraBackup libev package will need to be installed first. libev package can be installed from the EPEL repositories.
Percona yum Testing Repository
Percona offers pre-release builds from our testing repository. To subscribe to the testing repository, you’ll need to enable the testing repository in /etc/yum.repos.d/percona-release.repo. To do so, set both percona-testing-$basearch and percona-testing-noarch to enabled = 1 (Note that there are 3 sections in this file: release, testing and experimental - in this case it is the second section that requires updating). NOTE: You’ll need to install the Percona repository first (ref above) if this hasn’t been done already.

binary/redhat/7/x86_64/percona-xtrabackup-24-2.4.4-1.el7.x86_64.rpm
Now you can install Percona XtraBackup by running:
$ yum localinstall percona-xtrabackup-24-2.4.4-1.el7.x86_64.rpm
