I recently bought new hard drives for my NAS. This means that I'm copying all the data off the NAS, upgrading it, and then moving the data back.

I've gotten as far as copying the data from the NAS, but every file's modified/created date has been changed to when it was copied (today).

Is there a way, keeping in mind that I have the original data, to batch update the modified/created dates on the copied files without having to copy them over again (we're talking over a terabyte of data)?
