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:
Percona XtraBackup makes MySQL hot backups for all versions of Percona Server, MySQL, and MariaDB. It performs streaming, compressed, and incremental MySQL backups.
Percona XtraBackup works with MySQL, MariaDB, and Percona Server. It supports completely non-blocking backups of InnoDB, XtraDB, and HailDB storage engines. In addition, it can back up the following storage engines by briefly pausing writes at the end of the backup: MyISAM, Merge, and Archive, including partitioned tables, triggers, and database options.
Percona’s enterprise-grade commercial MySQL Support contracts include support for Percona XtraBackup. We recommend support for critical production deployments.

Footnotes
| [1] | InnoDB tables are still locked while copying non-InnoDB data. |
| [2] | Fast incremental backups are supported for Percona Server with XtraDB changed page tracking enabled. |
| [3] | Percona XtraBackup supports encryption with any kinds of backups. MySQL Enterprise Backup only supports encryption for single-file backups. |
| [4] | Percona XtraBackup performs throttling based on the number of IO operations per second. MySQL Enterprise Backup supports a configurable sleep time between operations. |
| [5] | Percona XtraBackup skips secondary index pages and recreates them when a compact backup is prepared. MySQL Enterprise Backup skips unused pages and reinserts on the prepare stage. |
| [6] | Percona XtraBackup can export individual tables even from a full backup, regardless of the InnoDB version. MySQL Enterprise Backup uses InnoDB 5.6 transportable tablespaces only when performing a partial backup. |
| [7] | Tables exported with Percona XtraBackup can be imported into Percona Server 5.1, 5.5 or 5.6+, or MySQL 5.6+. Transportable tablespaces created with MySQL Enterprise Backup can only be imported to Percona Server 5.6+, MySQL 5.6+ or MariaDB 10.0+. |
| [8] | Backup locks is a lightweight alternative to FLUSH TABLES WITH READ
LOCK available in Percona Server 5.6+. Percona XtraBackup uses
them automatically to copy non-InnoDB data to avoid blocking DML
queries that modify InnoDB tables. |
