MySQL 5.7 Reference Manual  /  ...  /  Configuration for NDB Cluster Backups

19.5.3.3 Configuration for NDB Cluster Backups

Five configuration parameters are essential for backup:

  • BackupDataBufferSize

    The amount of memory used to buffer data before it is written to disk.

  • BackupLogBufferSize

    The amount of memory used to buffer log records before these are written to disk.

  • BackupMemory

    The total memory allocated in a data node for backups. This should be the sum of the memory allocated for the backup data buffer and the backup log buffer.

  • BackupWriteSize

    The default size of blocks written to disk. This applies for both the backup data buffer and the backup log buffer.

  • BackupMaxWriteSize

    The maximum size of blocks written to disk. This applies for both the backup data buffer and the backup log buffer.

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.
