BACKUP DATABASE and RESTORE statements are not written to the binary log and therefore are not replicated to slaves. Nor is any data backed up or restored logged or replicated. However, for RESTORE, an incident event is logged unless SKIP_GAP_EVENT is specified. This event signals slaves that they should stop replicating because an event has occurred on the master that results in loss of master/slave synchrony.

For BACKUP DATABASE, the binary log coordinates comprising the backup validity point are written to the backup image and recorded in the backup_history log. To determine the validity point for a backup later, see Section 7.3, “Determining the Validity Point Associated with a Backup Image”.

If binary logging is not enabled, the validity point does not apply for BACKUP DATABASE, so it is not written to the backup image or backup_history. For RESTORE, no incident event is written.
