IMHO and from talking to a large number of people in startup leadership positions, many startups don’t even have a disaster recovery or business continuity plan let alone any formal backup process. Sometimes they have expressed doubt that such things are even necessary since they are using distributed systems. In a lot of ways what I’ve seen in that regard is similar to the way some people confuse a RAID array with having solved their backup problem. Your mileage may vary but this is common enough that not only is tape not part of it but even the backup concept is absent.
