By using continuous data protection, you can finally have some assurance of business resumption when something happens like a drive failure, human error or a data center disaster. CDP can also make disaster recovery testing much simpler. One of the biggest gaps in security I see when performing information risk assessments is this very issue: IT doesn't have the time or the means to actually test their disaster recovery procedures. Committing a DR plan to paper and hoping that it works out when needed is not a reliable DR strategy.
