I agree that noatime is a net win for *very* little pain. I found a
system where I had not mounted the datastore noatime and swiched it. In
my case, while it made a difference, it wasn't monumental:
With atime: 769 minutes for 675677MB.
With noatime: 609 minutes for 648224MB.
So, a 21% improvement. I'll take it, but it's not going to get my 3.5 day
backups under 12 hours! :)

I still have this on the (very) back burner. It's a Windows system, so
I'm looking at SMB, and I *hate* backups over SMB. They are nothing but a
problem.
