As an old timer, I see this as something that we all should be doing as normal operating procedures. When everything was part of a large in-house environment, smart companies had back/recovery procedures in place. In addition, if you were really smart, you also had system disaster and recovery practices which included hot-swap sites. It all boiled down to how long could you stay in business if you lost part or all of your IT services. I see today's cloud environment as no different, or maybe even more important since companies in a total cloud environment have even less control over their environment than before.
