25.6.8 Online Backup of NDB Cluster (original) (raw)

The next few sections describe how to prepare for and then to create an NDB Cluster backup using the functionality for this purpose found in the ndb_mgm management client. To distinguish this type of backup from a backup made usingmysqldump, we sometimes refer to it as a“native” NDB Cluster backup. (For information about the creation of backups with mysqldump, seeSection 6.5.4, “mysqldump — A Database Backup Program”.) Restoration of NDB Cluster backups is done using the ndb_restore utility provided with the NDB Cluster distribution; for information aboutndb_restore and its use in restoring NDB Cluster backups, seeSection 25.5.23, “ndb_restore — Restore an NDB Cluster Backup”.

NDB 8.0 makes it possible to create backups using multiple LDMs to achieve parallelism on the data nodes. SeeSection 25.6.8.5, “Taking an NDB Backup with Parallel Data Nodes”.
