This approach makes sense to me.

Until half a year ago, I used to have 3 external HD's - however, 1 is dysfunctional now, a 2nd one 
also starts to show first little signs of decay, a 3rd, newer one I recently lost. 

Soon, I can buy 1 new external HD, a 2nd one within a few weeks.  Later on I can purchase an 
extra storage device every 2 months or so. How many of them do I need all together in order to 
safely 'rotate' explained in the way above?

Do you format a new external HD into ext4 or do you keep using it's existing ntfs format? 

Can you explain a bit more about those 'home-brewed Linux scripts'? Are they similar to e.g.
