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.
Percona XtraBackup has the following benefits:
-
Complete a backup quickly and reliably
-
Process transactions uninterrupted during a backup
-
Save on disk space and network bandwidth
-
Verify backup automatically
Percona XtraBackup makes hot backups for Percona Server for MySQL and MySQL-compatible servers. XtraBackup takes streaming, compressed, and incremental server backups, and supports encryption.
Percona’s enterprise-grade commercial MySQL Support contracts include support for Percona XtraBackup. We recommend support for critical production deployments.
Supported storage engines¶
Percona XtraBackup can back up data from InnoDB, XtraDB, MyISAM, and MyRocks tables on MySQL {{vers}} servers as well as Percona Server for MySQL {{vers}}.
Percona XtraBackup supports the MyRocks storage engine. Percona XtraBackup copies all MyRocks files each time it takes a backup. An incremental backup on the MyRocks storage engine does not determine if an earlier full or incremental backup contains the same files.
