It turns out that my initial estimates regarding the required storage for Gee-Oh! map tiles were a little out…
I somehow came up with the figure 66Gb for 597871 squares (representing a full 4->10 run) but, having just completed a 4->9 run, things are actually looking a lot sweeter.
For the 66430 tiles already produced, it only required 2.2Gb of storage, and this scales up to only ~20Gb for the lot. Won’t hardly touch the sides of my available storage!
This means I can back up the entire UK quite handily when this is done (as well as quickly copy across to new server(s) etc. for scalability), and also be confident of expanding to other geographical areas (Europe and the US).
Anyway, that’ll do for now. I’ve just started the final run (to be completed in roughly 45 days…) Buh-byyyeee!
