Turning off iCloud backups does NOT delete the iCloud backup of that device. I've done this multiple times and am 100% sure of this.
Well, I am also 100% sure that turning off iCloud backup DOES come with deleting all your iCloud backup of that device. At least this is what I see in iOS 10.

Just turned off iCloud backup on the Air 2 (still on iOS 10.3.2). Nope, didn't delete the backup. I didn't expect it to anyway. I've got backups for iPads that I got rid of 3 months to 1 year ago still taking up space on iCloud (got the $0.99/50GB so at the moment, I don't exactly need the 1-2GB used per device).

My experience has been I have to manually delete backups from iCloud. Which totally makes sense. Someone could've just accidentally toggled the iCloud backup switch off or something and if Apple deleted iCloud backups based on that, it kinda defeats part of the purpose of backups (recovery from user error). :p

Anyway, I'm gonna have fun playing with it during the weekend. :)

Well, maybe I remembered it wrong. Could be possible.
At least in iOS 11, it does not delete backup by just turning it off.
 
I think one last question before I install the beta. What is the likelihood that the iOS 11 beta will corrupt data synced/stored on iCloud itself? Keychain, Photos, Contacts, Notes, Documents, etc?

Note, I do test beta (even alpha) operating systems all the time. The difference being it's very easy to sandbox those machines (or virtual machines as may be the case). Meanwhile iOS devices are pretty tied into cloud services so there's potential to affect my daily drivers which could be disastrous. :(

iCloud on beta OS is put in a dedicated server according to Apple. So I guess it will be fine.

Might you have a reference/source for that information? The Apple Beta Software FAQ is pretty sparse on details. Thanks!
 
"Factory Reset" is a misnomer. The correct term is "Erase all Content and Settings". This returns your phone to a like-new state, but preserves the currently installed version of iOS.

So if you install iOS 11 and then "Erase all Content and Settings" you'll start with an iOS 11 blank slate. You can also restore a backup from a previous iOS version if you like.

Can this be done from iCloud backups, or does it have to be from a backup done previously on my computer?
 
1. Backup using iTunes then go to "Prefs / Devices" and click Archive on that backup - it keeps it safe
2. Install the beta profile, reboot, install beta
3. Moan about battery drain and performance on Macrumours a few minutes after the upgrade completes.
You isssed step 4: wait 2-3'days and then start should about how this is the "best neta Apple has ever done"
