However, working under the assumption that
this trend will continue violates one of my basic principles of disaster recovery planning: assume the
worst.
I remember one of my first computer-upgrade purchases. It was two 4MB DIMMs (i.e., memory
cards) to increase my server??™s memory to a whopping 8MB. A month before I placed the order, the price
per DIMM was around $300. Shortly before I placed the order, a factory somewhere (Taiwan, I think)
burned down, and the price per DIMM nearly doubled. The moral of this story is that you never know
what could happen that might change the market price of disk storage. A key manufacturer could go
out of business, or solar flares could become a daily occurrence, endangering magnetic media worldwide.
Never assume that current costs will continue. I??™m writing this in 2007, and US gas prices are a
prime example. Does this principle border on the paranoid level? Of course. But that doesn??™t mean that
I??™m wrong about disk space possibly growing in cost. Absolutely not.
Personnel Availability
Most IT organizations are doing all they can to keep their heads above water, much less
focus on proactive activities.
