The "transparent" part is relatively easy to accomplish but secure partitioning is another thing entirely. Although most enterprise solutions only allow a given server to restore its own data, calling their authentication mechanisms "secure" is probably a stretch. There is a product that is coming out but is not generally available yet. That might offer you a solution. If you were to ask this question is a less private forum, I could probably put you in touch with the right people.
