Heh, I wasn't really thinking of applying the idea of Disaster Recovery to the plot but curiously the plan outlined by the MoM to Luxu (the Cornerstones of the World's Rebirth, I think) is analogous to a DR plan (where essential functionality of a system is restored and data retrieved in the event of a 'disaster' of some kind effecting the IT system).
The disaster is the destruction of the world by the Keyblade war and the DR plan is sending the Dandelions to another worldline so that the light lives on and they can eventually cause the world to be reborn.
