Reminds me of this gem:

That gets you RAID1 (between the server and your wife). for another layer of redundancy with no hardware investment, ask your wife to share your little mishaps with her mother. Far better availability and reliability than the best SAN.

If a person (adult or child) cannot make an effort to make the game enjoyable for the other player, the other player won't play for long.
