That would be correct Terry, if Sony manufactured their camera lines in multiple facilities distributed geographically. However, these factories made headphones, Alpha A65 cameras, and NEX-7 cameras and kit lenses. Those product lines are now at zero output. Therefore, Sony may have multiple production facilities, but they are running a limited part of the line card with no provision for covering the loss of another facility.
And no, recovering a lost IT facility is no different than recovering a lost manufacturing plant. You don't just plunk a mainframe computer and all of its attending systems and infrastructure in a convenient closet somewhere. It takes the same amount of planning, manpower, and resources to put one of those up as it does to deploy a manufacturing/assembly facility.
Yes, I know that some computer companies make IT "pods" (for lack of a better term) in shipping containers, but those are emergency systems and not for permanent installations.
