"It's nearly impossible for small companies to get disaster recovery right," Hecht said. They may not be equipped to discover the underlying data dependencies that can affect operations between two critical applications. For example, data coming in to a database from a business intelligence (BI) application may increase by a magnitude that necessitates configuration changes to hardware or storage, which might not be reflected right away in a DR plan. Even in a testing scenario, these configuration changes may lengthen restoration times for both the BI app and the database that processes the data."
