摘要： A data storage system includes non-volatile data storage including a container partition and a browsable partition and control circuitry configured to backup a file in the non-volatile data storage at least in part by receiving the file from a host, the file including a plurality of chunks of data, storing the plurality of chunks of data in the browsable partition of the non-volatile data storage, determining that one or more of the plurality of chunks has been modified, storing the one or more modified chunks in a container partition of the non-volatile data storage, determining a new chunk associated with each of the one or more modified chunks, and storing the one or more new chunks in the browsable partition of the non-volatile data storage.

摘要： 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.

摘要： Systems and methods are disclosed for backing up data in a computing system including a controller configured to backup a file in the non-volatile memory at least in part by receiving the file from a host, the file including a plurality of chunks of data and storing the plurality of chunks of data in a browsable partition of the non-volatile memory in response to said receiving the file. The controller further determines that one or more of the plurality of chunks has been modified, determine a new chunk associated with each of the one or more modified chunks, store the one or more new chunks in the browsable partition of the non-volatile memory using the communication interface in response to said determination of the one or more new chunks and store the one or more modified chunks in a container partition of the non-volatile memory using the communication interface.
