Data Storage Group Assigned Patent

Compression for archiving

Data Storage Group, Inc., Longmont, CO, has been assigned a patent (8,832,045) developed by two co-inventors for “data compression and storage techniques.”

The co-inventors are Brian Dodd, Longmont, CO, and Michael Moore, Lafayette, CO.

The abstract of the patent published by the U.S. Patent and Trademark Office states: “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.

The patent application was filed on May 2, 2012 (13/462,664).
