When your operating system (Windows, Linux, etc.) is running, it has a vice-like grip on system files. You cannot create a perfect image of the C: drive while Windows is using it because many files will be locked or in a state of flux. While R-Drive Image can perform "hot" backups while the OS is running using VSS (Volume Shadow Copy Service), the only way to guarantee a 100% pristine, perfect sector-by-sector backup is to operate outside of the OS.
