About a month ago I was in an infrastructure meeting discussing backup strategy. The conversation was around disk based backups such as near store and Virtual tape libraries.
So I asked the question “do we know how these disk based backup system cope with earth quakes?”
As yesterdays data could be on the same disk that is being access today, a disk level corruption could be “interesting”
As the point in time I got laughed at, “Earthquakes, yeh right !”
Does not seem such a silly question now does it !
