I use iCloud to store, backup, and sync my phone photos. I use a couple of 2/4TB drives to back up my photos taken on my DSLR/Film cameras. I manually copy over directories to redundant drives. I keep one 4TB drive that's the final backup, and it's unplugged and kept in a safe in my house. Every couple months, I pull it out, backup the newest photos to it and return it to it's safe. I know it's a little extreme, but I have tons of photos and want to keep multiple backups.
