Yep. I've recently began using rsync for several types of "local" copy,
usually back-up related. I can't recall if the "cp -a" detects and
handles hard-links to minimize space requirements though. I know cpio
can/does. I guess I'll have to read up on cp some more and see if it
leaves the access times alone (cpio parameter allows retaining that) and
handles hard-links efficiently.
