I have auto-backup set to wifi only. When away from wifi, I take a photo and decide not to keep it so I delete it from the gallery app, however, when I go into the G+ Photos app there is a notification saying the photo is queued up to auto-backup. I do not want this deleted photo to auto-backup. Today I took 34 photos while messing about with the new Nexus 5 camera app, even though I have now deleted them from my phone when I get home from work they will auto-backup which is a nuisance. There must be a way to prevent this?
