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.
