Abstract
Systems and methods for commonality factoring for storing data on removable storage media that may allow for highly compressed data to be stored efficiently on portable memory devices. The methods include breaking data into unique chunks and calculating identifiers, e.g., hash identifiers, based on the unique chunks. Redundant chunks can be identified by comparing identifiers of other chunks to the identifiers of unique chunks. When a redundant chunk is identified, a reference to the existing unique chunk is generated such that the chunk can be reconstituted in relation to other chunks in order to recreate the original data. One or more of the unique chunks, the identifiers, and/or the references may be stored on the portable memory device. Hardware and/or software for the chunking and/or hashing functions can reside in a host computer, a removable storage device or cartridge, and/or a removable cartridge holder.
