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 using mysqldump, we sometimes refer to it as a “native” NDB Cluster backup. (For information about the creation of backups with mysqldump, see Section 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 about ndb_restore and its use in restoring NDB Cluster backups, see Section 25.5.23, “ndb_restore — Restore an NDB Cluster Backup”.

也可以使用多个 LDM 创建备份，以在数据节点上实现并行。请参见 第 25.6.8.5 节，“使用并行数据节点进行 NDB 备份”。It is also possible to create backups using multiple LDMs to achieve parallelism on the data nodes. See Section 25.6.8.5, “Taking an NDB Backup with Parallel Data Nodes”.
