help with batch file

right now im working on a batch file to backup my psp but the only problem i have with it is that if i delete a file on my psp then back it up it wont delete it on the backup.
here is how i have it now

@echo off
echo Ok to back up?
pause
cls
echo updating backup from psp...
xcopy K:\ H:\"psp stuff"\"Back up" /c /s /r /d /y /i
echo Done, push any key to exit
pause

The K drive is where my psp is and the H drive is another partition on my hard drive where I save some stuff
