Volume Shadow Copies are created on a weekly basis or when new software or update is added to the system. Usually, the VSS is scheduled to run automatically two times a day.

Restoring files and folders with VSS is simple and you can do it by following these steps:
- Locate the file or folder you wish to restore, right-click it and choose Properties.
- Go to the Previous Versions You should see all the available backups there.
- Now click on Copy or Restore buttons to restore the file or folder. Bear in mind that the Restore option will overwrite the selected file or folder.
