If the user ID and group ID cannot be preserved, no error message
is displayed and the exit value is not affected ( ex:
cp /user/you/file mycopy )
If the source file has both "set user ID" and "set group ID" and
either cannot be preserved, neither bits are preserved.
If the destination file exists, its contents are overwritten, but its mode, user ID, and group ID are unchanged unless

Symbolic links are copied, rather than indirected through.
Hard linked files are copied files, This causes additional space to be required and the files in the destination directory are not longer linked.
To preserve hard links, use tar,
