20090112945 | DATA PROCESSING APPARATUS AND METHOD OF PROCESSING DATA - Data processing apparatus comprising: a chunk store containing specimen data chunks, a manifest store containing a plurality of manifests, each of which represents at least a part of a data set and each of which comprises at least one reference to at least one of said specimen data chunks, a sparse chunk index containing information on only some specimen data chunks, the processor being operable to: process input data into input data chunks; identify manifests having at least one reference to one of said specimen data chunks that corresponds to one of said input data chunks and on which there is information contained in the sparse chunk index; and prioritize the identified manifests for subsequent operation. | 04-30-2009 |
20090113167 | DATA PROCESSING APPARATUS AND METHOD OF PROCESSING DATA - Data processing apparatus comprising: a chunk store containing specimen data chunks, a manifest store containing at least one manifest that represents at least a part of a data set and that comprises at least one reference to at least one of said specimen data chunks, a sparse chunk index containing information on only those specimen data chunks having a predetermined characteristic, the processing apparatus being operable to process input data into input data chunks and to use the sparse chunk index to identify at least one of said at least one manifest that includes at least one reference to one of said specimen data chunks that corresponds to one of said input data chunks having the predetermined characteristic. | 04-30-2009 |
20100223441 | STORING CHUNKS IN CONTAINERS - Chunks are stored in a container of a data store, where the chunks are produced by dividing input data as part of a deduplication process. In response to determining that the size of the container has reached a predefined size threshold, at least one of the chunks in the container is moved to another container. | 09-02-2010 |
20120047328 | DATA DE-DUPLICATION FOR SERIAL-ACCESS STORAGE MEDIA - Data storage and retrieval methods and apparatus are provided for facilitating data de-duplication for serial-access storage media such as tape. During data storage, input data is divided into a succession of chunks and, for each chunk, a corresponding data item is written to the storage media. The data item comprises the chunk data itself where it is the first occurrence of that data, and otherwise comprises a chunk-data identifier identifying that chunk of subject data. To facilitate reconstruction of the original data on read-back from the storage media a cache ( | 02-23-2012 |
20120293344 | COMPRESSING AND DECOMPRESSING DATA - A technique includes compressing or decompressing data using a relative displacement of a location of a data pattern. | 11-22-2012 |

20140215289 | PROVIDING MEMORY PROTECTION USING A MODIFIED ERROR CORRECTION CODE - Data and a corresponding initial error correction code is written to a first portion of a memory device. Based on an error in the first data and the initial error correction code, the initial error correction code is modified. | 07-31-2014 |
20140340778 | De-Duplication - A method and apparatus for data de-duplication is disclosed. Use de-duplication engine (DDE) divides data into regions. The DDE processes the regions in a serial fashion. The DDE clears its hash table before processing the first region. Each region is divided into a number of chunks. A hash is generated for each chunk in a region. When a hash for a chunk is not in a hash table, the hash is stored in the hash table and the chunk is stored on media. When the hash is a duplicate of a hash already in the table, the hash and chunk are discarded and a reference to the previously stored chunk is stored to the media. The DDE does not retain all the hashes from all the regions in the hash table at the same time. The DDE only retains the hashes for the current region being processed and N previous regions where N is a positive integer greater than zero. | 11-20-2014 |

20150248248 | WRITING STANDARD TAPE FORMAT TO MEMORY - The present disclosure provides techniques for writing data in standard tape format to solid state, non-volatile storage medium. A cartridge disposed within a non-volatile memory storage (NVM) drive may contain an inexpensive, solid state, non-volatile storage medium rather than magnetic tape. The NVM drive may write data to the solid state, non-volatile storage medium. Improved cost savings may thus be seen. | 09-03-2015 |

20150278017 | MEMORY MODULE HAVING ERROR CORRECTION LOGIC - A memory module includes an error correction logic to provide data error protection for data stored in the memory module. The error correction logic is selectively controllable between an enabled state and a disabled state. Data stored in the memory module is without error protection provided by the memory module if the error correction logic is in the disabled state. | 10-01-2015 |

20100198792 | DATA PROCESSING APPARATUS AND METHOD OF PROCESSING DATA - Data processing apparatus comprising: a chunk store having a plurality of chunk sections, each operable to store specimen data chunks, the apparatus being operable to: process an input data set into one or more input data chunks; identify a specimen data chunk in one of said chunk sections which corresponds to a first input data chunk; identify a second input data chunk not corresponding to a specimen data chunk in the chunk store; and store the second input data chunk as a specimen data chunk in proximity to the identified specimen data chunk corresponding to the first input data chunk. | 08-05-2010 |
