Re: Error while trying ndb_restore

Hi Nisa,

as long as your data was restored without any key violations there is no need to rerun.

Each data node produce their own backup files, containing the data for that node. You need to run ndb_restore once for each node.

See https://dev.mysql.com/doc/refman/8.0/en/mysql-cluster-programs-ndb-restore.html
| ndb_restore must be executed once for each of the backup files that were created
| by the START BACKUP command used to create the backup (see Section 23.6.8.2,
| “Using The NDB Cluster Management Client to Create a Backup”). This is equal to
| the number of data nodes in the cluster at the time that the backup was created.
