I worked for a startup a few years back where the CEO deleted the entire 1+TB database/website when the server was hacked and being used as a spam server because he 1. didn't know who to disable the site short of deleting and 2. could reach anyone that did know how.

The next morning he told us to restore the site from backups and fix the security hole. That's when we reminded him, again, that he had refused to pay for backup services for a site of that size.

We all ended up looking fro new jobs withing a couple days.
