Shadow Copy, also known as Volume Snapshot Service, is a data backup technology included in Microsoft Windows that allows the operating system to take snapshots of the system which include files which are locked or otherwise inaccessible to the user. The service can only be used on NTFS-based disks and interacts with the data at the block level.
Shadow Copy is integral to the Windows Backup and System Restore utilities. For a more in depth look at how Shadow Copy works, check out HTG Explains: What are Shadow Copies and How Can I Use Them to Copy or Backup Locked Files?
