Abstract

Systems and methods are disclosed for performing file backup and restore in a computing system. Certain embodiments provide a communication interface for communicating with a non-volatile memory and a controller configured to determine that a file stored in the non-volatile memory has been modified, identify a chunk of the file that has been modified, determine a new chunk associated with the modified chunk, the new chunk reflecting the modification, generate a separate chunk file including the new chunk and a filename, and storing the chunk file in the non-volatile memory using the communication interface.
