Abstract

Official abstract text for this publication.

Described in detail herein are systems and methods for managing single instancing data. Using a single instance database and other constructs (e.g. sparse files), data density on archival media (e.g. magnetic tape) is improved, and the number of files per storage operation is reduced. According to one aspect of a method for managing single instancing data, for each storage operation, a chunk folder is created on a storage device that stores single instancing data. The chunk folder contains three files: 1) a file that contains data objects that have been single instanced; 2) a file that contains data objects that have not been eligible for single instancing; and 3) a metadata file used to track the location of data objects within the other files. A second storage operation subsequent to a first storage operation contains references to data objects in the chunk folder created by the first storage operation instead of the data objects themselves.

First claim

Opening claim text (preview).

We claim: 1. A method of deduplicating data performed by one or more computing systems, each computing system having a processor and memory, the method comprising: receiving an indication of a first storage operation; creating a first directory associated with the first storage operation, wherein the first directory includes three files, wherein the first file of the first directory stores data associated with the first storage operation, and wherein the data in the first file…
