Unfortunately complacency about how reliable modern hardware is can lead to neglecting things like off site backups. And other issues. Yeah your one big critical on premises server may be super reliable. But what happens when the building is flooded with 6 ft of water, catches on fire, is leveled in an earthquake, or anything else?

If a function is super critical to business, it also deserves to have some thought put into the blast radius of its failure.

The sort of places that would insist on rolling a live server 700 ft across a parking lot probably don't have any real disaster recovery plan.
