-  InnoDB tables are still locked while copying non-InnoDB data.
-  Fast incremental backups are supported for Percona Server with XtraDB changed page tracking enabled.
-  Percona XtraBackup supports encryption with any kinds of backups. MySQL Enterprise Backup only supports encryption for single-file backups.
-  Percona XtraBackup performs throttling based on the number of IO operations per second. MySQL Enterprise Backup supports a configurable sleep time between operations.
-  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.
-  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.
-  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+.
