No account is currently storing backed up data

[AC Question]

This question has been asked a thousand times, but I don't see an intelligent reply or solution yet, so let me try.
My Lenovo Yoga YT3 tablet running Android 5.1.1 is prompting me for a System Update "you system can update to the latest version").
But, it is also warning me, scarily, that "this update will erase ALL data.... please back up etc.etc."

However, under Backup and Reset I am getting the message above: "No account is currently storing backed up data"
even though I have 2 accounts setup under Google.

How do I associate one of these accounts (ideally a different one than my phone is backing up to) for backup storage?

thanks
Peter

alas, the Yoga IS greyed out. saying "your device already has this installed"

Weird. I suppose it's possible that older devices might not auto-update Google Play Services as quickly -- or perhaps older devices stay on older versions for longer.

Sorry, I'm stumped.:-\ How important is it for you to backup your settings and app data? For me, the most important data is safely saved to the Google cloud (like my Google Drive files, Google Keep notes, Google Contacts, Google Photos, etc.). That kind of data doesn't require the backup service to be on -- just the main Auto-Sync for your Google account.

I managed to fix the issue, by doing this:

1) (this step might not have helped, try steps 2+3 first, then this one and the second and third again if they alone didn't suffice) deleted all app-data of Google account manager and Google backup transport in settings-> apps
2) I rebooted
3) I removed updates of the Google play services app (the button where normal non-system apps can be uninstalled) in settings-> apps, waited a few minutes and updated the app again via the play store (several Google apps complained and demanded an update of the g services app, and also a notification appeared asking me to set up the backup account)

No such luck - Google Play Services in the nougat update is the latest, so you can't roll back a version (as there is nothing to roll back to)
