Whether it’s recounting a story, watching a video, or enjoying photos with family and friends, our memories help us reconnect with what’s really important. And every month, nearly a billion people use WhatsApp to do just that.
Of course: you don’t want your memories stuck on your phone. (What if something happens?!) So starting today, WhatsApp for Android lets you create a private backup of your chat history, voice messages, photos, and videos in Google Drive. And once you do, you can restore everything on a new device with just a couple taps.

The new backup feature is rolling out over the next few months, so keep an eye on your WhatsApp settings to see if it’s available.
