I upgraded a MySQL cluster from version 7.3.10 to 7.4.9 and got the message, that the configuration parameter "BackupMemory" is depricated.
The hint "use Total memory allocated for backups per node (in bytes) instead" is wrong, because it contains the description of "BackupMemory" instead the name of the new configuration parameter(s).
The same could be true for "DiskCheckpointSpeedInRestart" and "DiskCheckpointSpeed".

How to repeat:
Start the management server of a 7.4.9 cluster with the parameter "BackupMemory" activated in the configuration file (config.ini) with "--initial".

Suggested fix:
Change the hint or remove it.
