Not accurately.  They can detect that a file is sparse by comparing
the st_size and st_blocks fields returned by stat().  They can't
accurately differentiate between a block of NULs and a non-allocated
block in a sparse file.  AFAIK, the only utility that can exactly
reproduce a sparse file is dump/restore.
