rsync doubt

does anyone knows how to use rsync to generate an "image" of a directory?

i want to create a dir exactly the same as /home (Drive 1) in Drive 2

using the minimum ammount of transfers/cpu (so it would re-send just files that were modified or doesn't exist anymore...should also delete files that were deleted and so on, keep permissions, owner, etc...)

thanks
