Certainly, if your business impact analysis (BIA) says you have to keep key data replicated for rapid recovery. In other words, you need a very short, a very fine-grained recovery time objective (RTO) of maybe an hour or so. That means you're going to have to have data backed up, data protected, data replicated or mirrored at some other location, some other venue, so you can get to it very quickly. If you have another site, if you have another facility you can leverage, if you have a partner that you can leverage, certainly you can put that into play. If not, you're going to have to look at some provider, whether it's a traditional disaster recovery site, a DR service, a managed service provider or some facility that you can then leverage as part of your restoration. That's also the level of your recovery – are you recovering an entire business are you just recovering a particular application or part of that application?
