微信重大更新！网友：聊天记录终于有救了！

WeChat has unveiled a significant upgrade to its chat history backup system, introducing new functionalities that improve convenience, flexibility, and data security for users.

The update now allows users to back up WeChat chat history directly to external storage devices, including USB drives and portable hard drives. Even in shared-device scenarios—such as family members using the same storage for backups—data remains isolated, ensuring privacy and preventing interference.

The new Auto Backup feature eliminates the need for manual backups. Once configured, WeChat will automatically initiate backups whenever the phone connects to the designated computer or external storage device.

Switching to a new device is now simpler—users no longer need to log in to WeChat on their old phone. Instead, scanning a QR code on the new device instantly transfers chat history.
