Method for protecting backup data of a computer system from damage

摘要

Methods for protecting backup data of a computer system from damage are disclosed. A first storage device is provided for storing the backup data of the computer system, wherein the first storage device is ordinarily disabled to prevent the operating system of the computer system from accessing the backup data. A pin on the motherboard of the computer system is triggered by the Basic Input Output System (BIOS) of the computer system to enable or disable the first storage device. A first software system management interrupt is then initiated to call the BIOS to enable the first storage device. The backup data stored in a second storage device of the computer system is then copied to the first storage device. Finally, a second software system management interrupt is initiated to call the BIOS to disable the first storage device after copying of the backup data is complete.
