Windows 11 includes a feature called Shadow Copy, which allows users to create backups of files and maintain a history of previous versions. To set up Shadow Copy, users must use Task Scheduler to automate backups. The process involves creating a new task, configuring triggers and actions, and ensuring specific settings are enabled. Backed-up files are stored in a hidden folder and can be accessed through the Previous Versions feature in File Explorer. Users can also utilize System Restore and File History for additional backup options. Shadow Copy has been part of Windows for over two decades and is designed to protect against accidental deletions or modifications, but not against hardware failures or theft.
