Also super long term archives are stored on magnetic tapes, they consume virtually 0 energy
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
That's for backups. You wouldn't have it as the only storage method because it's so inconvenient to get the data.
