  • [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.
