I worked at my last job for a place with a single rack mounted set of Windows servers at a data center - with no backup power supply, no backups of any kind for that matter, no UPS and no redundancy of any system, plus they didn't even have an admin for 6 months. The CEO refused to spend money on a 2nd anything. The company has 2000 employees. One server held all of the companies photos (which is basically the core of the business) and of course was not backed up.
