"Reset All Settings" / Resetting iTunes Backup Encryption Password
I want to make a backup of an iPad, but it has a backup encryption password set. I didn't set it and don't know what it is. So I want to turn off the backup encryption.
I've seen that you can reset the iTunes backup encryption password, by doing "Reset All Settings". This is not supposed to remove any data but does remove knowledge of networks, network passwords, customization of the home screen, etc. It does seem to reset a lot to do "Reset All Settings".
I see also that there are more "focused" partial resets, under "Reset All Settings". For instance, "Reset Home Screen Layout" and "Reset Location & Privacy".
I'm wondering if any of these-- specifically, "Reset Location & Privacy"-- might reset the backup encryption password? Or do I really have to do the blanket "Reset All Settings" which includes all of these?
