In walking through our course labs one more time, I found that when backing up the Farm in "Full" mode, if you cannot resolve the various service applications through the web service WCF services, the entire backup will pause on "In Progress" indefinitely.
I found that when uninstalling Office Web Apps, you will be left with an instable farm. One side effect is that your services will start failing and will be set to "Stopped". I noticed that several of my Windows Services are not starting autmatically for some weird reason (no, its not a password and yeah, I can see the DC). Even after setting them back up property and starting the services, the backup would never fully continue. I have yet to find a resolution!!!
