Flirting with disaster
espite this unpredictability, many organizations needlessly increase their exposure. One way that they do this is through self-delusion. By this, I mean that their recovery expectations bear no semblance to their actual ability to recover. This is typically the result of either an outdated DR infrastructure or just a lack of serious attention to DR processes.
Another area of exposure is created by not understanding application interdependencies. Today's mission-critical applications consist of components that often reside on a multitude of servers, as well as numerous cross-application data dependencies that must be considered for successful recovery. These dependencies frequently span the boundaries between the mainframe and open-systems worlds, often an organizational chasm. Without a solid understanding of how data flows among these applications, it is very possible to have a situation in which each server is individually recoverable, yet, due to lack of appropriate synchronization, the application can't be recovered properly. This scenario inevitably adds many hours or days to th
