Hello again and thanks for taking the time to scan this month’s
VAN newsletter. This month’s small reader bonus is below and relates to the next
topic. We sincerely hope you enjoy it.
Next month, we will have one article on Continuous
Data Protection (CDP) and begin a Storage Virtualization series co-authored by
Symantec’s Frank Bunn. This material was originally available through the Storage
Network Industry Association (SNIA). Through special considerations, SNIA is enabling
us to make these publications available to VAN readers. We look forward to having you read them.

Sea Change
When it comes to the world’s oceans, there is only one constant it is:
- Unpredictable
- Salty
Well, OK, maybe there is more than one constant. Yet, despite an ocean’s
predictable unpredictability, an irresistible allure usually exists for a variety of maritime
sports sailing, surfing, swimming, etc.
A fundamental assumption involved in these activities is that sporting participants
can reasonably expect to return to dry land alive and well. But, since the future is genuinely unknowable,
this underlying assumption is an expectation necessarily based on partial knowledge, or perhaps a belief that if something
has not happened, then it can never happen.
But, every now and then, something totally unexpected occurs.
For example, in Australia’s 1998 Sydney to Hobart sailing race, hurricane force weather struck with a vengeance.
Most of the participants had never endured anything like it; some unfortunately did not survive.
A fundamental truth is that, in many endeavors, people tend to base their actions in probabilities,
not the impact of possible outcomes. In the 1998 Sydney to Hobart sailing race, the probability of disaster was
low since it hadn’t happened before (though it had in the August 14, 1979 British Fastnet race). But, it wasn’t zero
and its occurrence proved breath-takingly instructive for some, literally.
What might have proven more useful than probability-based decision making would have been an expected
value calculation of the outcome if such an event did occur. Here, the expected value would have comprised
multiplying a low probability times a great cost, producing a value that might well have been
found substantially more informative.
In the final analysis, we all decide when to use and not to use safety nets.
Sometimes we do it with our data as well, knowingly and unknowingly. Though the probability
of data loss may seem small, the possible outcome can be lethal for the enterprise, large or small.
As we write this, Hurricane Wilma has just reached category 5 strength.
With an 882mb pressure reading, Hurricane Wilma is now regarded as the most intense hurricane on record in
the Atlantic basin enough said.
To end on a somewhat lighter note, it is useful to recall John Maynard Keynes’s famous quote:
"In the long run, we are all dead"
While it may be true, just don’t let it unnecessarily let it happen to your enterprise’s data.
Keep your data safe...back it up enough said.
See you next month. Until then, keep your data safe.
Best regards,
The VAN Team
