The other being a network socket in this case? But that socket might be two servers over? Meh, ideally they've optimized that as well.
So absolutely it is a network problem which means custom fiber?

Oh, sorry — by "copying bytes from one to the other," I meant copying bytes from the disk to the network interface controller on the same physical computer. It's true that beyond that it'll depend on the network topology connecting you to where you want the data to be, and how fast the machines in between and on the other end are!
I don't know enough about custom fiber to know whether that will help stretch past being network-bottlenecked — most NICs max out at 10 gigabits/second, but I've heard of faster ones. Eventually you might be able to make yourself disk-limited... Either way, backing up one file is probably easier than backing up a zillion files scattered around the filesystem.
