    About Percona XtraBackup¶

    Percona XtraBackup is the world’s only open-source, free MySQL hot backup software that performs non-blocking backups for InnoDB and XtraDB databases. With Percona XtraBackup, you can achieve the following benefits:

    • Backups that complete quickly and reliably

    • Uninterrupted transaction processing during backups

    • Savings on disk space and network bandwidth

    • Automatic backup verification

    • Higher uptime due to faster restore time

    Percona XtraBackup makes MySQL hot backups for all versions of Percona Server for MySQL, and MySQL. It performs streaming, compressed, and incremental MySQL backups.

    Important

    Percona XtraBackup 2.4 supports MySQL and Percona Server for MySQL 5.6 and 5.7 databases. Due to changes in the MySQL redo log and data dictionary formats, the Percona XtraBackup 8.0.x versions are only compatible with MySQL 8.0.x, Percona Server for MySQL 8.0.x, and compatible versions.

    Percona’s enterprise-grade commercial MySQL Support contracts include support for Percona XtraBackup. We recommend support for critical production deployments. Percona XtraDB Backup supports encryption.

    Supported storage engines¶

    Percona XtraBackup works with MySQL and Percona Server. It supports completely non-blocking backups of InnoDB, XtraDB, and MyRocks storage engines. Fast incremental backups are supported for Percona Server with the XtraDB changed page tracking enabled.

    In addition, it can back up the following storage engines by briefly pausing writes at the end of the backup: MyISAM and Merge, including partitioned tables, triggers, and database options. The InnoDB tables are still locked while copying non-InnoDB data.

    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.

    What are the features of Percona XtraBackup?¶

    Here is a short list of the Percona XtraBackup features. See the documentation for more.

    • Create hot InnoDB backups without pausing your database

    • Make incremental backups of MySQL

    • Stream compressed MySQL backups to another server

    • Move tables between MySQL servers on-line

    • Create new MySQL replication replicas easily

    • Backup MySQL without adding load to the server

    • Percona XtraBackup performs throttling based on the number of IO operations per second

    • Percona XtraBackup skips secondary index pages and recreates them when a compact backup is prepared

    • Percona XtraBackup can export individual tables even from a full backup, regardless of the InnoDB version

    • Backup locks is a lightweight alternative to FLUSH TABLES WITH READ LOCK available in Percona Server. Percona XtraBackup uses them automatically to copy non-InnoDB data to avoid blocking DML queries that modify InnoDB tables.
