> Finally, whether you consider a change in failure rate even from 2% to 33% significant really depends on how much you value your data and how hard it is to get it back. For the average user, the answers are "A lot," and "Nearly impossible." Raise your hand if you've backed up in the last week.
I've done that today. Admittedly, having shell access to four seperate servers in different locations is uncommon for normal users.
In the end it is a matter of definition what a weak correlation ends and a strong correlation starts. I wouldn't speak of a strong correlation if I'd lose money when betting on the correlated event. So for me it would have to be x% -> 50+%.
