Which Systems Are Critical?

About this interactive

Before choosing how to back something up, decide what you are trying to achieve, and for which systems. The lesson's test is the cost of an outage. An e-commerce site that makes money every minute is critical: downtime is expensive, so it deserves fast recovery and more spending. A simple corporate site that few people visit is not. Internal systems count too. If developers, sales or support staff lose thousands of dollars a day in productivity when a system is down, that system is critical. Most organizations run more than one critical system, and each gets its own backup objectives.
