How to automate Backup in mysql cluster

[David Marois]

We have a mysql cluster.  I know we can make backup in the management server of the mysql
cluster with the command "start backup".
 
But how we can automate it ?
 
Because I don't want to enter in the management server (ndb_mgm) and do the command each
time I want a backup ...
 
Thanks !
