This section lists any performance-related features and settings in MySQL Server versions that affect various aspects of the backup process.
Some new MySQL 5.6 features introduce changes in directory layout and file contents for InnoDB tables. Backing up servers that use these features requires MySQL Enterprise Backup 3.8.1 or higher:
The group commit feature in MySQL 5.6 reduces the frequency of
flush operations for the
redo log, relying more on the
binary log to ensure consistency. Because MySQL Enterprise Backup
does not back up or replay transactions from the binary log, the
InnoDB tables might correspond to a
time during the backup, before the
FLUSH TABLES WITH READ
LOCK phase, while the data from
InnoDB tables corresponds to the time when
FLUSH TABLES WITH READ LOCK phase starts.
See Section D.2, “Changes in MySQL Enterprise Backup 3.8.1 (2013-02-05)” for details on the fixes and enhancements related to these MySQL 5.6 features.
