Volume Shadow Copy Service (VSS) hardware and software shadow copy providers manage running volumes and create shadow copies of them on demand. A hardware provider manages shadow copies at the hardware level by working in conjunction with a hardware storage adapter or controller. A software provider manages shadow copies by intercepting I/O requests at the software level between the file system and the volume manager.
