Backup management

Supported storage engines

Percona XtraBackup can back up data from InnoDB, XtraDB, MyISAM, and MyRocks tables on MySQL 8.0 servers as well as Percona Server for MySQL with XtraDB, Percona Server for MySQL 8.0, and Percona XtraDB Cluster 8.0.

Version updates

Version 8.0.6 and later supports the MyRocks storage engine. An incremental backup on the MyRocks storage engine does not determine if an earlier full or incremental backup contains the same files. Percona XtraBackup copies all MyRocks files each time it takes a backup. Percona XtraBackup does not support the TokuDB storage engine. Find more information in Percona TokuBackup.


Percona XtraBackup 8.0 does not support making backups of databases created in versions prior to 8.0 of MySQL, Percona Server for MySQL or Percona XtraDB Cluster. As the changes that MySQL 8.0 introduced in data dictionaries, redo log and undo log are incompatible with previous versions, it is currently impossible for Percona XtraBackup 8.0 to also support versions prior to 8.0.

Due to changes in MySQL 8.0.20 released by Oracle at the end of April 2020, Percona XtraBackup 8.0, up to version 8.0.11, is not compatible with MySQL version 8.0.20 or higher, or Percona products that are based on it: Percona Server for MySQL and Percona XtraDB Cluster.
