So i do a ton of photoshoots all the time and need to backup constantly. Ive been manually doing this and it's an enormous pain. I have an internal drive and 3 external drives. when i d/l my images i then put them in the "pictures" folder. What i need to do is have only that "pictures" folder backed up to ALL 3 drives every night. I cannot have any files deleted from any of the external drives...but periodically when my internal drive fills i delete the images from that. I cannot figure out a smooth way for all this to take place. Can someone please help me so that all my photos are backed up every night to all 3 external drives. Thank you so so so much in advance!!!
