An apparatus, system, and method quickly backs up data in an emergency
situation and reduces battery backup dependence. The apparatus may
include a backup module and a dedicated computer readable storage device.
The backup module interfaces with system memory and selectively transmits
modified data to the storage device in response to a detected system
failure. The dedicated storage device stores the modified data around the
outer edge of a hard disk in order to increase write performance. The
system may include the backup module, the storage device, a plurality of
client devices, and a plurality of storage devices. The method includes
storing modified and unmodified data, detecting a system failure, and
transmitting modified data stored in a memory module to a dedicated
computer readable backup device. Upon rebooting the device, the method
may include restoring the modified data to the system memory and
destaging the modified data to the plurality of storage devices.
