Abstract: Provided 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.

Abstract: The inventive systems/techniques described herein provide solutions to managing information that may be integrated with many existing back-up applications. The techniques use existing resources, and provide transparent access to additional data processing functionalities. In one arrangement, a data de-duplication technique is provided. The technique includes monitoring a computer system to identify an intended transfer of a data set to an electronic storage medium. Once an intended transfer is identified, the data set is processed (e.g., prior to transfer). Such processing includes identifying a portion of the data set that corresponds to previously stored data and replace that portion of the data set with a link to the previously stored data. Such replacement of data portions within the first data set with links to previously stored data defines a modified data set. The modified data set may be transferred to the electronic storage medium associated with, for example, a back-up application/system.
