I suspect that with the size of the files your camera produces and the number you have, the speed of upload would prohibit that unless you leave it to work by itself for a week or just upload five photographs ;-) OK, I exaggerate but you get my drift. Uploading is slow and when you consider the price of the storage you'd need, I suspect an external drive would be a better option. Assuming once on there files would not change frequently if ever so you could even ask a neighbour to store it for you to guard against fire or theft.
