ndb_restore — Restore an NDB Cluster Backup rewrite-database=db2,db3  restores all tables and data from databases  db1  and  db2  into database db3 . When restoring from multiple backup databases into a single target database using  --rewrite-database , no check is made for collisions between table or other object names, and the order in which rows are restored is not guaranteed. This means that it is possible in such cases for rows to be overwritten and updates to be lost. This option causes  ndb_restore  to ignore corrupt tables while reading a native  NDB  backup, and to continue restoring any remaining tables (that are not also corrupted). Currently, the  --skip-broken- objects  option works only in the case of missing blob parts tables. It is possible to restore data without restoring table metadata. By default when doing this,  ndb_restore fails with an error if a mismatch is found between the table data and the table schema; this option overrides that behavior. Some of the restrictions on mismatches in column definitions when restoring data using  ndb_restore are relaxed; when one of these types of mismatches is encountered,  ndb_restore  does not stop with an error as it did previously, but rather accepts the data and inserts it into the target table while issuing a warning to the user that this is being done. This behavior occurs whether or not either of the options  -- skip-table-check  or  --promote-attributes  is in use. These differences in column definitions are of the following types: This option causes  ndb_restore  to ignore any schema objects it does not recognize while reading a native  NDB  backup. This can be used for restoring a backup made from a cluster running (for example) NDB 7.6 to a cluster running NDB Cluster 7.5. 4391 • --skip-unknown-objects •Different distribution key settings •Different default values •Different  STORAGE  settings ( MEMORY ,  DISK ) •Different  COLUMN_FORMAT  settings ( FIXED ,  DYNAMIC ,  DEFAULT ) • --skip-table-check ,  -s • --skip-broken-objects Important Command-Line Format --skip-broken-objects Command-Line Format --skip-table-check Command-Line Format --skip-unknown-objects Command-Line Format --slice-id=# Introduced 8.0.20-ndb-8.0.20 Type Integer • --slice-id = #
