摘要： Apparatus, methods, and other embodiments associated with object synthesis are described. One example apparatus includes logic for identifying a block in a data de-duplication repository and for identifying a reference to the block. The apparatus also includes logic for representing a source object using a first named, organized collection of references to blocks in the data de-duplication repository and logic for representing a target object using a second named, organized collection of references. The apparatus is configured to synthesize the target object from the source object. Since synthesis may be complicated by edge cases, the apparatus is configured to account for conditions including a block in the target object needing less than all the data in a source object block, data to be used to synthesize the target object residing in a sparse hole in a data stream, and the target object needing data not present in the source object.

摘要： Example systems and methods concern a sub-block parser that is configured with a variable sized window whose size varies as a function of the actual or expected entropy of data to be parsed by the sub-block parser. Example systems and methods also concern a sub-block parser configured to compress a data sequence to be parsed before parsing the data sequence. One example method facilitates either actually changing the window size or effectively changing the window size by manipulating the data before it is parsed. The example method includes selectively reconfiguring a data set to be parsed by a data-dependent parser based, at least in part, on the entropy level of the data set, selectively reconfiguring the data-dependent parser, based, at least in part, on the entropy level of the data set, and parsing the data set.
