Percona XtraBackup - Documentation¶
This documentation is for the latest release: Percona XtraBackup 2.4.28 (Release Notes).
Percona XtraBackup is an open-source hot backup utility for MySQL - based servers that does not lock your database during the backup. 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.
Support for InnoDB 5.1 builtin has been removed in Percona XtraBackup 2.1
For a high-level overview of many of its advanced features, including a feature comparison, please see About Percona XtraBackup.
Whether it is a 24x7 highly loaded server or a low-transaction-volume environment, Percona XtraBackup is designed to make backups a seamless procedure without disrupting the performance of the server in a production environment. Commercial support contracts are available.
Percona XtraBackup 2.4 does not support making backups of databases created in MySQL 8.0, Percona Server for MySQL 8.0, or Percona XtraDB Cluster 8.0. Use Percona XtraBackup 8.0 for the version 8.0 databases.
