The main difference is, that then, "backup" ment copying everything by hand, and now, it means one simple copy-paste. Considering the size and price of modern hard drives, and relatively small size of old archives, any one individual can backup a huge amount of data (and even offer/share it as a download link/torrent seed/etc).

Their whole Library would probably fit even on a smallest now-available sd card.
