Reminds me of a joke/morality story/PHB discussion/consulant caution
The weather services tells everyone to leave the river bottom, a flood is coming. Well, the sheriff drives by this old farmer's house and tells them to evacuate. The farmer tells the sheriff, he is staying as the Lord will provide. The water starts rising and the farmer has to move up to the second floor. A boat comes by to help the farmer leave. The farmer says he is staying, the Lord will provide. The water rises more and now the farmer is on the roof. A helicopter comes to rescue the farmer. The farmer tells the helicopter he is staying as the Lord will provide. The farmer drowns. The farmer is at the gates of Heaven and is really mad that he drowned. He tells St. Peter that he had his faith and was let down. St. Peter says, "well, we sent a car, a boat, and a helicopter. What more did you want?"
Just because you don't think the solution is the most dramatic one, does not you should not use it. Some other fancy solution might not be right for you or not in the form you think it should be in.
Here, spanned DVDs are the easiest solutions. Maybe DVD-/+RW fits the bill, but plain old -+R is less than $2 a piece and fairly reliable. Blu-Ray is that miracle from above at the moment (well, so it the railgun

.) But tape is good too, just harder to ship in this day of security.
