Before WhatsApp, I cannot think of any app which have served so many mobile users across the planet who could text and send files to each other with so much of ease. WhatsApp is available for Android, iOS and Windows Mobile platforms and allows you to stay in touch with almost all your friends without paying anything to your service provider (assuming most of your friends own a smartphone).
One of the biggest privileges that we need from any messaging or emailing service is whether it could let you recover any of your deleted messages. And the fact that WhatsApp lets you recover deleted messages, images and videos that have been shared does make it a pretty solid app.
I am sure that most of the WhatsApp users are not aware of the fact that this messaging service takes backup of all the shared stuff every 24 hours and it keeps the backup files intact for last 7 days. Yes, it's true. And there is a way which would let you use those backup files to restore things.
So, below are two ways to recover lost Whatsapp data.
Method 1 This is a simple and pretty straightforward way to restore deleted WhatsApp stuff. All you need to do is uninstall the app and install it back. This would actually use all the backup files, and restore whatever it can.
Method 2 This app stores its backup files by the name, msgstore-YYYY-MM-DD.1.db.crypt. Below are the locations where you can find these backup files for respective OS: Android: /sdcard/WhatsApp/Databases/msgstore.db.crypt iOS: net.whatsapp.WhatsApp/Documents/ChatStorage.sqlite Assuming that you have the backup file now, first thing that you need to do is launch a web service, Recover Messages which would actually get you going in this whole journey to recover stuff.
Click on the Select SQLite File, choose the backup file, click on I Accept (only after reading terms) and then on Scan button. It would take some time, depending on backup file size and your internet speed, and would list all the contents.
Now, click on the appropriate tab to recover the lost data.
