Methods, computer program products, computer systems, and the like are disclosed that provide for improved deduplication performance using prefetched backup information. For example, such methods, computer program products, and computer systems can include generating new feature information for a new backup image, (for each existing backup image in a plurality of existing backup images) comparing the new feature information with existing feature information for the each existing backup image, identifying one or more existing backup images of the plurality of existing backup images, and prefetching the one or more existing backup images. The feature information is generated as an output of a machine learning process. The machine learning process receives at least a portion of data of the new backup image as an input. The one or more existing backup images are identified based, at least in part, on a result of the comparing.

Methods and systems for improved deduplication performance using prefetched backup information

Disclosed are techniques that provide for deduplication in an efficient and effective manner. For example, such methods, computer program products, and computer systems can include generating new feature information for one or more portions of a new backup image, generating first container range information by performing a container range calculation using the new feature information, generating existing feature information for one or more portions of an existing backup image, generating second container range information by performing the container range calculation using the existing feature information, determining a container range affinity between the first container range information and the second container range information, identifying at least one portion of the one or more portions of the existing backup image using a result of the determining, and prefetching the one or more fingerprints corresponding to the at least one portion of the one or more portions of the existing backup image.
