Actually, that's highly doubtful. A backup solution will have to be able to actually restore a meaningful fraction of the stored data to be useful. Worse yet, if seeking is expensive, even smallish but scattered amounts of data can be problematic. Tapes suffer from that big time. They've grown in storage space, comparable to hard drives, but since it's normal to have libraries with many tapes per drive, there's severe practical utility limits even for backups.
