Percona Server and Percona XtraBackup

We have been providing an enhanced version of MySQL for many years. We call it Percona Server with XtraDB, and some of the largest MySQL installations in the world rely on it every day. We also provide XtraBackup, the world’s only free and open-source InnoDB hot backup tool.

This page used to contain links to MySQL patches. Those patches are now available in Percona Server, and the code is hosted on Launchpad.
