Backup feature is almost non existent The app stores chats locally so option to back up chat history is very important if you lose or change your phone. Yet in WhatsApp it's underdeveloped to put it mildly. There's no way to specify location for backup There's no way to restore from backup other than uninstall/install the app. You have to jump through hoops to use local backup. Conclusion: don't trust any backup features if your chat history is of any importance to you.
