While the trainer is running, press ‘S’ to save, then ‘B’ to backup. Look for the folder labeled ‘model/_autobackups’. Here you will find all of the backups in folders numbered from newest to oldest. You can save the newest backup to another location and delete the rest of the folders if you wish. You can also set the trainer to backup the model by setting ‘Autobackup every N hour ( 0 – 24 )’ to your desired interval. Maximum number of backups is 24, however I suggest you clear them out regularly.
