You need something to happen to drive archiving. It's bureaucratic minutiae that the President doesn't give a hoot about until something bad happens. The CIO of the IRS doesn't wake up one morning and decide to start archiving stuff. The chief counsel probably wants to delete everything (except for his stuff)

Same thing in the private sector. Nobody outside of regulated industries like pharma archived email, ever until Enron. Everyone didn't start doing it until the Federal courts changed the rules of civil procedure several years ago.
