What is Shadow Copy?

Shadow Copy is a service for you to create backup copies or snapshots of computer files and volumes, and it also called Volume Shadow Copy service (known as VSS or snapshot) which is available for Windows XP, Vista, 7, 8, 8.1, 10, Windows Server 2003, 2008 (R2), 2012 (R2), 2016, 2019. And there are two tools for shadow copy: DiskShadow and VssAdmin.
