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
XtraBackup makes MySQL hot backups for all versions of Percona Server, MySQL, MariaDB, and Drizzle. It performs streaming, compressed, and incremental MySQL backups.
Percona XtraBackup works with MySQL, MariaDB, Percona Server, and Drizzle databases (support for Drizzle is beta). 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 XtraBackup. We recommend support for critical production deployments.

|||MyISAM backups require a table lock.|
|||XtraBackup performs throttling based on the number of IO operations per second. MySQL Enterprise Backup supports a configurable sleep time between operations.|
|||XtraBackup tunes the operating system buffers to avoid swapping. See the documentation.|
|||XtraBackup is linked against the MySQL client libraries, so it behaves the same as standard MySQL command-line programs. MySQL Enterprise Backup has its own command-line and configuration-file behaviors.|
