How about copying files on disk? You could use "find" and/or "grep" to find the messages (= files); use hardlinks if you're sure that no message will be modified; use reflinks if the filesystem supports them; or simply copy from your current area to the archive again and again, if it's not too much data; use "fdupes" to remove duplicates (= identical content in differently named files) if there's a chance for duplicates being created.
