MySQL 8.0 Reference Manual Including MySQL NDB Cluster 8.0

23.5.8.3 Configuration for NDB Cluster Backups

Five configuration parameters are essential for backup:

In addition, CompressedBackup causes NDB to use compression when creating and writing to backup files.

More detailed information about these parameters can be found in Backup Parameters.

You can also set a location for the backup files using the BackupDataDir configuration parameter. The default is FileSystemPath/BACKUP/BACKUP-backup_id.

In NDB 8.0.22 and later, you can enforce encryption of backup files by enabling RequireEncryptedBackup. When this parameter is set to 1, backups cannot be created without specifying ENCRYPT PASSWORD=password as part of a START BACKUP command.
