Not if you host with a real cloud provider.
I do not disagree with you on the fact that you should always make backups. But a TRUE cloud infrastructure doesnt include a single point of failure. You need to make sure your data is not on the hard drives of the actual server, but on a SAN that has redundancy. In a true Virtual environment, if you server completely shits the bed, your VM should be easily transfered to the next physical host, because all the data lies on the SAN. The network should have redundant switches, redundant servers, redundant power supplies, etc and the data center should have a generator. This will technologically leave you with no single points of failure. Most people dont do this.
Find a provider that uses VMware virtualization platform. It is second to none, make sure they are using a quality name brand SAN like EMC, NetApp, HP etc. The problem is most people are not knowledgeable on these technologies and hear 'Cloud' and get all excited and are easy sales targets.
But yes, If you dont have a backup everyday, you are not taking your business seriously.
