One drive

3. I turned mine off because my ISP was threatening to raise fees

I shoot hundreds of photo raw files every day, and the network traffic to back them all up to OneDrive way exceeded my service plan. The ISP said reduce bandwidth or pay for a more expensive data plan. Instead, I disabled One Drive and built my own NAS. I back up all my photo directories on the NAS and also back up the final, focus stacked results on Dropbox. So one file sent to cloud backup for each image and hundreds stored locally. Actually, I save all the directories onto removable USB drives first, and the NAS copies them from there. All the USB drives are physically stored in a box after they're full, so the raid NAS is further backed up by the intermediate pass through drives.
