If you are a WhatsApp user, then you know that there is a feature called “backup messages.” This is a way for you to store your important messages in case something happens to your phone. To use this feature, you need to create a backup file called “backup.txt” and save it on your phone. Then, when something happens to your phone and you don’t have the original message or backup file, you can access the message by going to the “Message” tab and looking for the backup message.
