Abstract: In a data backup method of a storage device, environment information is received from at least one environmental sensor such that an operating environment in which the storage device is operating is monitored. An event detection signal is generated based on the environment information. In response to generating the event detection signal at least first data is immediately backed up to an external device located outside the storage device. The storage device includes a first port configured to be used to store the plurality of data in the storage device, and a second port different from the first port. In response to generating the event detection signal, the at least first data among the plurality of data are immediately output from the storage device through the second port.
