Not sure if I'm going to be able to keep my island, but I've put enough work into it that if I have to pull the plug on it, I'd like to archive it in such a way that if I get one again in the future, I can 'push button' return it to the way mine currently is. I doubt this is even remotely possible, especially for the terrain of the island ... but even if it was just the prims/locations/etc, that would be helpful. Any utility that could help with this?
