Also super long term archives are stored on magnetic tapes, they consume virtually 0 energy
That's for backups. You wouldn't have it as the only storage method because it's so inconvenient to get the data.
tape storage is for offline storage, and any data storage on it would also be redundant
writing and reading tape archives takes a lot of computing. usually you have your tape library server and a server hosting the app and then the tape sled. tape takes a lot of energy
so deleting it electronically is going to take a more energy
it's more efficient to overwrite it or use a degaussing device to wipe the tape
