With regard to the "duplicate" relation specifically, it is currently
defined <http://tools.ietf.org/html/draft-bryan-metalinkhttp-04#section-8>as:

Refers to a resource whose available representations are byte-for-byte

I'm glad I checked because my first reading of duplicate was in the verb "to
copy" and as such I would very much prefer an unambiguous term like
"replica" be used. "mirror" is another option but it too could be construed
as a verb (e.g. in the context of CDN management).
