The error appears because – by default – the 'C:\System Volume Information' folder is accessible only from the SYSTEM account. if you try to access the 'System Volume Information' folder and its contents using Windows explorer, then you'll receive a warning message that says: 'C:\System Volume Information is not accessible – Access Denied'. The 'C:\System Volume Information' folder is a hidden system folder that the System Restore tool uses to store its information and restore points.
