Data compression and storage techniques

Abstract

patent_PN7,860,843Provided are systems and methods for use in data archiving. In one arrangement, compression techniques are provided wherein an earlier version of a data set (e.g., file folder, etc) is utilized as a dictionary of a compression engine to compress a subsequent version of the data set. This compression identifies changes between data sets and allows for storing these differences without duplicating many common portions of the data sets. For a given version of a data set, new information is stored along with metadata used to reconstruct the version from each individual segment saved at different points in time. In this regard, the earlier data set and one or more references to stored segments of a subsequent data set may be utilized to reconstruct the subsequent data set. Read more…
