this is what happened in that time:

 $ rsync -aWuq --delete-before --progress /home/bmike1/Documents /media/bmike1/GORILLA64
^C
rsync error: received SIGINT, SIGTERM, or SIGHUP (code 20) at rsync.c(632) [sender=3.1.0]
rsync error: received SIGINT, SIGTERM, or SIGHUP (code 20) at io.c(521) [generator=3.1.0]
 $
I then removed the quiet flag and:
 $ rsync -aWu --delete-before --progress /home/bmike1/Documents /media/bmike1/GORILLA64
