According to multiple user reports, WeChat's iOS version is currently undergoing a gray-scale test of a brand-new backup feature. As shown in the UI, this feature supports various storage devices, including computers and USB drives, allowing for automatic backups.

This new feature is a significant improvement over the existing backup functionality, providing users with more flexibility and convenience. The fact that WeChat is investing in this feature suggests that the company is committed to enhancing the user experience and providing a more comprehensive set of features.

However, it's worth noting that this feature is still in the gray-scale testing phase, which means that not all users will have access to it immediately. WeChat may be testing the feature with a small group of users before rolling it out to the general public.

In any case, this development is a positive sign for WeChat users, and we can expect to see more features and improvements in the future.
