Can G+ on iOS 7 Auto Backup photos in the background?
A coworker recently purchased a Nexus 7 to compliment his iPhone 5. He would like to view his iPhone pictures on his Nexus 7.
I suggested using G+ purely for the Auto Backup feature, as the photos would appear in the Nexus 7 gallery automatically, and he could also view his tablet photos on his iPhone via the G+ app. I'm not sure, however, whether G+ can update in the background on the iPhone. I know there were some changes with background apps in iOS 7, so I wanted to ask before I made any assumptions.
So, can G+ on iOS 7 run Auto Backup in the background, and can it be scheduled (on wifi, while charging)? If not, is there an alternative cross-platform way to handle this? Ideally, the solution would require no user interaction (like how iCloud backup works, or how G+ works on Android).
