First I copy everything into one folder, and then I copy that to two hard drives. Every few years I buy two new drives, copy the old backup, add all of the new files from the last few years. Old drives are thrown away, because I don't trust hard drives for more than a few years. Also I use cloud services like onedrive and icloud, so the only way I'll ever need my backup drives is if one of those services dies.
