$ man cp
(中略)
-a, --archive
Preserve as much as possible of the structure and
attributes of the original files in the copy (but
do not preserve directory structure). Equivalent
to -dpR.
(中略)
By default, sparse SOURCE files are detected by a crude heuristic and
the corresponding DEST file is made sparse as well. That is the behav-
ior selected by --sparse=auto. Specify --sparse=always to create a
sparse DEST file whenever the SOURCE file contains a long enough
sequence of zero bytes. Use --sparse=never to inhibit creation of
sparse files.
(デフォルトでは--sparse=autoなので、sparseは適切に対応される)
