Patent Issued for Reducing Storage Costs Associated with Backing up a Database

September 11, 2014

By a News Reporter-Staff News Editor at Computer Weekly News -- From Alexandria, Virginia, VerticalNews journalists report that a patent by the inventors Barsness, Eric L. (Pine Island, MN); Darrington, David L. (Rochester, MN); Santosuosso, John M. (Rochester, MN), filed on November 17, 2010, was published online on August 26, 2014.

The patent's assignee for patent number 8818955 is International Business Machines Corporation (Armonk, NY).

News editors obtained the following quote from the background information supplied by the inventors: "Databases are computerized information storage and retrieval systems. The most prevalent type of database is the relational database, a tabular database in which data is defined so that it can be reorganized and accessed in a number of different ways.

"Regardless of the particular architecture, in a database management system (DBMS), a requesting entity (e.g., an application or the operating system) demands access to a specified database by issuing a database access request. Such requests may include, for instance, simple catalog lookup requests or transactions and combinations of transactions that operate to read, change and add specified records in the database. These requests are made using high-level query languages such as the Structured Query Language (SQL). Illustratively, SQL is used to make interactive queries for getting information from and updating a database such as International Business Machines' (IBM) DB2, Microsoft's SQL Server, and database products from Oracle, Sybase, and Computer Associates. The term 'query' denominates a set of commands for retrieving data from a stored database. Queries take the form of a command language that lets programmers and programs select, insert, update, find out the location of data, and so forth."

As a supplement to the background information on this patent, VerticalNews correspondents also obtained the inventors' summary information for this patent: "Embodiments of the invention provide a computer-implemented method, computer program product, and system for performing an operation that includes receiving a first request to back up at least a first unit of data stored in a database. The operation also includes generating a backup of: (i) less than all of the first unit of data and (ii) at least part of the second unit of data, responsive to the first request and a determination that the first unit of data is, at least in part, derived from a second unit of data stored in the database. The operation also includes receiving a second request to restore at least the first unit of data from the backup. The operation also includes restoring all of the first unit of data from the backup, based on a predefined relationship between the first unit of data and the second unit of data and responsive to the second request."
