WhatsApp is all set to delete all your data? | Social Media
“WhatsApp backups that haven’t been updated in more than one year will be automatically removed from Google Drive storage. To avoid the loss of any backups, we recommend you manually back up your WhatsApp data before November 12, 2018,” WhatsApp stated on its FAQ page.
“You can back up your chats and media to Google Drive, so if you change Android phones or get a new one, your chats and media are transferable. We recommend connecting your phone to Wi-Fi prior to backing up your chats via Google Drive, as backup files can vary in size and consume mobile data, causing additional charges,” WhatsApp added.
