I noticed recently that WhatsApp automatically backups messages. I get a popup every now and then when I am using WhatsApp which says "Backing up messages". I don't want WhatsApp to backup my messages. I went into the WhatsApp settings and clicked 'Chats and calls -> Chat backup' and it says:
Local: 3:00am Google Drive: Never
Google Drive settings shows that my settings are set to 'Never back up to Google Drive'.
With that said, how do I prevent it from backing up locally?
