So last time I saw this discussed on HN [1], people said there were tape backups of all these files and that they would be fully recovered. Some people said they worked adjacent to this tape backup system. I'm inclined to believe they weren't lying and that the tape backup system does exist. So why weren't they able to recover from tape? Is the tape backup more limited than people reported, and this data wasn't backed up? Was it just too difficult and expensive to scan the tapes and decide which was the canonical version of each file?

If the number of users with lost files google may take a long time or not want to do the recovery.

  Imagine. "Your data is backed up idempotently and permanently to tape, but you are too unimportant for us to ever recover your data loss from tape." Charitably, the whole system is on tape and piecemeal restoration is impossible. This is why professionals practice their restoration protocols regularly. Not to imply that it's reasonable to treat customers of commodity SaaS as professionals.
