Percona XtraBackup - Documentation¶
Percona XtraBackup is an open-source hot backup utility for MySQL - based servers that doesn’t lock your database during the backup.
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 can back up data from InnoDB, XtraDB, and MyISAM tables on MySQL 8.0 servers as well as Percona Server with XtraDB, Percona Server 8.0, and Percona XtraDB Cluster 8.0.
Percona XtraBackup 8.0 does not support making backups of databases created in versions prior to 8.0 of MySQL, Percona Server 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.
