You could mitigate that in the future by making a copy of the current 
tileset at a fixed point (1st of january for example).

But I agree that it would need quite some space for a gimmick. But with 
Seagate announcing 16TB drives and prices of drives dropping steadily, I 
assume this argument will be laughed at in 5 years time.
