Is it possible to copy the entire contents of my Hard drive to my

external drive that is not stored on my computer hard drive that I

option.
Yes.
Instead of the default "backup everything", tell CCC to do an
Incremental Backup AND check all three boxes below that option.
Those three options taken together mean that you'll end up with a
clean clone that contains everything from the source plus you'll have
an archive folder, called "_CCC", that will contain all the files it
found on the destination that weren't on the source. Those files
will be neatly placed in a folder tree that is the same as where they
came from originally. Additionally, any other top level folders you
had will be left alone.
This is the way you should do incremental backups normally. Then,
once in a while, go into the _CCC folder and prune it down, as you
see fit. Apple's Time Machine kindof does the same thing, btw,
except that it provides a pretty browser and automatically
destructively prunes without your say-so.
