Thanks. I had stopped G+ from backing up for the time being but I want to turn it back on once I figure out the duplicate issue so I can continue to us it in the future. I guess I'm wondering how Google Plus decides if a pictures has already been uploaded or not?
It's going to suck manually deleting all the duplicates already on plus.google.com/photos. I have over 7,000 pictures in there and the best I can tell from my G+ app on the phone, it recently uploaded about 3,000. My google fu isn't very good though because I can find no way to sort them by date uploaded or anything. It'll be a nightmare scrolling through all of my photos looking for the duplicates.
