ndb_restore — Restore an NDB Cluster Backup a newer version of MySQL to an older cluster, but you must use a copy of ndb_restore  from the newer NDB Cluster version to do so. For example, to restore a cluster backup taken from a cluster running NDB Cluster 7.5.23 to a cluster running NDB Cluster 7.4.33, you must use the ndb_restore  that comes with the NDB Cluster 7.5.23 distribution. For more rapid restoration, the data may be restored in parallel, provided that there is a sufficient number of cluster connections available. That is, when restoring to multiple nodes in parallel, you must have an  [api]  or  [mysqld]  section in the cluster  config.ini  file available for each concurrent ndb_restore  process. However, the data files must always be applied before the logs. Command-Line Format --backup-password=string Introduced 8.0.22-ndb-8.0.22 Type String Default Value [none] This option specifies a password to be used when decrypting an encrypted backup with the  --decrypt option. This must be the same password that was used to encrypt the backup. The password can be up to 256 characters in length, and must be enclosed by single or double quotation marks. It can contain any of the ASCII characters having character codes 32, 35, 38, 40-91, 93, 95, and 97-126; in other words, it can use any printable ASCII characters except for  ! ,  ’ ,  " ,  $ ,  % ,  \ , and  ^ . In MySQL 8.0.24 and later, it is possible to omit the password, in which case  ndb_restore  waits for it to be supplied from  stdin , as when using  --backup-password-from-stdin . Command-Line Format --backup-password-from-stdin[=value] Introduced 8.0.24-ndb-8.0.24 Type Boolean Default Value FALSE Command-Line Format --backupid=# Type Numeric Default Value none When used in place of  --backup-password , this option enables input of the backup password from the system shell ( stdin ), similar to how this is done when supplying the password interactively to mysql  when using the  --password  without supplying the password on the command line. This option is used to specify the ID or sequence number of the backup, and is the same number shown by the management client in the  Backup  backup_id  completed  message displayed upon • --backup-password= password • --backup-password-from-stdin[=TRUE|FALSE] • --backupid = # ,  -b 4372
