Phone backups continually fail. Not one backup has been successful since putting the phone into service in mid 2021. ETA... In response to a link provided by Google about what data is archived: This phone was put into service in April, 2021. NO data has been saved. NO backup has been successful. The error tells me to keep the phone plugged in and keep it connected to WiFi. It's kept charged and is connected to WiFi - yet the app itself reports nothing was backed-up, and my drive stats show 0 bytes used. Broken app - do not trust your data to this.
