When looking at my photos in the Google+ app, at the bottom is a footer that says "Backup failed" with a retry button. The backup still fails when I click Retry.
Is there a way to find out why Auto Backup is failing so I can correct the problem?
Try deleting Google+ data/cache, then start Google+ app. It will log you in and then you can choose Auto Backup setting. You can then go to Sync settings, untick "Sync Google+ Auto Backup" and then tick it again. Seems to work for me. You can also go to the Google+ app settings and get it to upload all your photos/videos to start the sync.

Another solution that worked for me was turning off Standard size in the Auto Backup settings altogether. When taking a new 8MP jpg using my camera and when Photo Size was set to Full Size in Google+, all the photos seem to be successfully uploading without error. This further confirms that the error is arising when Google+ is trying to convert larger jpgs to standard size.
I tried taking pictures at different resolutions, from 1.9MP to 8MP. 3.8MP and below uploaded without a problem. Anything with a higher resolution still failed.
So, the solution for now seems to be:
I found the solution for me to be that I had the sync setting turned off. I went to my settings -> notification drawer -> tiles and layout and then I put the sync button in my drop down tiles which I must have turned off thinking it was the orientation button because they have similar looking icons. Once that was turned on everything synced normally again :)

If your device's photos and videos aren't being saved to your Google account, try checking your backup status:
Open the Google Photos app on your mobile device . At the top left, touch the Menu icon > Assistant. Read the first card. If it says:
- "Waiting for connection" or "Waiting for Wi-Fi": You either need to change your settings or connect to a Wi-Fi or mobile network. Touch the card to change your settings.
- "Back up & sync is off": Touch "TURN ON" on the card to back up your device's photos and videos, including ones that you capture in the future.
- "A photo or video was skipped": A photo or video on your mobile device doesn't meet our upload requirements: Photos must not exceed 75 MB or 100 megapixels Videos must not exceed 10 GB
- "Backing up photos" or "Backup complete": This means that your photos and videos should be saved.
