The above comparison is based on XtraBackup version 1.4 and MySQL EnterpriseBackup version 3.5 on December 7, 2010. Notes:
- MyISAM backups require a table lock.
- XtraBackup performs throttling based on the number of IOoperations per second. MySQL Enterprise Backup supports a configurablesleep time between operations.
- XtraBackup can copy files in parallel as of version 1.5,currently in Beta.
- XtraBackup tunes the operating system buffers to avoidswapping. See thedocumentation.
- XtraBackup is linked against the MySQL client libraries, so itbehaves the same as standard MySQL command-line programs. MySQL EnterpriseBackup has its own command-line and configuration-file behaviors.
