[mirror-admin] Fastest way to copy data between two servers?

My old Fedora mirror is going to be retired and replaced newer hardware.
I need to copy data between the two and I'm wondering what the fastest
way is going to be? Usually I'd just rsync + SSH between them but that's
probably not the most efficient for 3TB of data. Then I started
thinking, what if I NFS mounted the old one and used rsync + NFS instead.

I suppose the absolute fastest would NFS + "cp -a"?  That doesn't give
me any recovery if it crashes. The transfer is going to take a long
time, so I'm pretty sure I want rsync for recoverability. Any
suggestions on best practices to move a large amount of data like this?
