All the data sits in internal storage , drive has acces to it , you see when you go to drive it says back up but you cant open it .
Ok, so I guess whatsapp backup files that users can access and copy and paste are only the files inside the phone whatsapp folder, and not from google drive?
If my phone is lost/stolen, then I buy new phone I think there is a copy of whatsapp backup inside google drive and can only be restored by using whatsapp drive?
Anyway, I saw screenshots at https://www.quora.com/WhatsApp-In-w...-does-WhatsApps-chat-backup-feature-save-data
and video at 4:50min https://www.youtube.com/watch?v=Sh-u3vHy2vk showing the Google Drive whatsapp not greyed out.
