Would you be able to share a link or example for the auto backup you are trying to achieve. Like any reference links or any other vendor links you have referred due to which you may be looking for that feature with these switches.
I can maybe look into the links you share to understand better on how it can be achieved using a command on the switch and could let you know if such a feature is present on our switches.
I referred management guide to check but could not find such options. Please take a look at the below link and let me know if there are any concerns.
