32.7. MySQL Cluster as Disaster Prevention

MySQL Cluster uses an architecture in which multiple processes act as cluster nodes that provide multiple copies of table data. This use of multiple processes is not in itself a backup technique, but it does provide data redundancy that lessens the potential for data loss if any given node becomes unavailable. Thus, the likelihood that you'll need to resort to disaster recovery techniques is reduced. Adding more nodes increases redundancy further.

See Section 29.7, "The Cluster Storage Engine," for a general description of MySQL Cluster architecture, and the MySQL Reference Manual for detailed discussion.
