Microsoft has developed a new backup app for Windows 11 that allows you to store a backup of your Windows installation in the cloud, making it convenient when you want to restore your computer or transfer settings, apps, and other data to a new computer.
Microsoft writes about the new feature in Windows 11:
Building on the app restore feature we announced last year, we are introducing additional backup and restore capabilities in this build to make moving to a new PC easier than ever and to help app developers retain users across this new PC transition. The goal of these changes is to land users on a desktop that feels familiar to them and get them back to productivity within minutes on their new PC.
The new backup app for Windows 11 is currently only available to those who download Windows 11 Insider Preview Build 23466. It is unclear when the feature will be available to all Windows 11 users.
