  That changes the command meaning, which is why the deletions.

rsync --blah-blah-blah /home/teddy /media/backup

...is equivalant to...

rsync --blah-blah-blah /home/teddy/ /media/backup/teddy

  The trailing slash after teddy says "do not create a subdirectory at
the destination.  Just copy direct to destination".  To summarize...

rsync --blah-blah-blah /home/teddy fubar/
...copies the contents of teddy to fubar/teddy

rsync --blah-blah-blah /home/teddy/ fubar/
...copies the contents of teddy to fubar
