That's right. The suggestion Peace gave is totally
correct. Command 'cp -r' won't keep the owner, group
orignal information. The information will be kept as
the user who command. 'tar' will keep the orignal information
. I am sorry that what I mention before was confused.(I use
'copy to' in my sentence) And I think use 'mv' is the
most dangous command in the case. It's still worse
than 'cp' because you can not resotre the former
information but 'cp -r' can.
