This option can be used to restore a backup taken from one node group to a different node group. Its argument is a list of the form source_node_group , target_node_group . 

• --ndb-nodeid 

<img src='content_image/735552.jpg'>

Set node ID for this node, overriding any ID set by --ndb-connectstring . 

• --ndb-optimized-node-selection 

<img src='content_image/735553.jpg'>

Do not read default options from any option file other than login file. 

• --nodeid = # , -n 

<img src='content_image/735555.jpg'>

Specify the node ID of the data node on which the backup was taken. 

When restoring to a cluster with different number of data nodes from that where the backup was taken, this information helps identify the correct set or sets of files to be restored to a given node. (In such cases, multiple files usually need to be restored to a single data node.) See Section 23.4.23.2, “Restoring to a different number of data nodes” , for additional information and examples. 

In NDB 8.0.15 and later, this option is required.
