Yes, it seems that "cp -a" is designed just for that kind of job.
Might have to add "-x" to limit it to one file system if you are
interested.
I noticed that, to my surprise, rsync is sometimes faster than a plain
scp even when the destination is empty, and as someone else said it's
nice to be able to stop/start and redo.

I'm not sure why you should care about atime so much - more and more
people around (including Linus Torvalds) recommend to get rid of it
altogether. Ubunut comes with "relatime" as a default config already.
According to Linus, disabling atime updates will give the single
largest performance gain (in dozens of percentages, as far as I
remember).
But back to the question - am I missing something too by not using
dump/restore or cpio? dump/restore is so BSD 4/'80's :)
