How to make full backup? My phone is a Nokia 6.1. I'd like to do a factory reset, but preserving:


my personal files
the settings of all apps
the data saved by all apps (e.g. the alarms saved by the stock Clock app)
the collection of apps (I want them to be reinstalled after the reset)


Does the "Settings -> Advanced -> Backup" Android feature do all that? If no, then what part does it do?
Found the answer here:

If you back up to Google Drive, here's what's backed up:

Google Contacts data
Google Calendar events and settings
Wi-Fi networks and passwords
Wallpapers
Gmail settings
Apps
Display settings (brightness and sleep)
Language and input settings
Date and time
Settings and data for apps not made by Google (varies by app)
Note: Not all apps can back up or restore all settings and data. To find out about an app, learn how to contact its developer.
