Previously, an Xbox Live Gold subscription was required to use cloud saves, but the requirement is going away with the launch of the next generation of Xbox consoles.
Xbox 360 Cloud Saves Will No Longer Require Gold Subscription
As per a blog post about backwards compatibility:
“Preserving the games of our past is fundamental to our DNA at Xbox and our continued promise to you,” Microsoft explains. “Backward compatibility lets you experience your cherished gaming memories again and in new ways. Your favorite games retain everything the original developer intended while experiencing enhancements and exciting new features.”
Making cloud save transfers free would mean you can continue playing where you left off back on your Xbox 360, even if you skipped the Xbox One generation entirely.
With many of the games loading much faster thanks to the console's NVME storage, as well as offering higher framerates and resolution, the Series X and Series S could be the best place to place your classics.
Interestingly, Microsoft noted that because it isn't capable of 4K output, the Series S will run Xbox One S versions of games.
"To deliver the highest quality backwards compatible experience consistent with the developer’s original intent, the Xbox Series S runs the Xbox One S version of backward compatible games while applying improved texture filtering, higher and more consistent frame rates, faster load times and Auto HDR."
