METHODS AND SYSTEMS FOR AFFINITY AWARE CONTAINER PRETECHING

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 retrieving container information for a first one or more containers of a plurality of containers of one or more backup images (where the one or more backup images were produced under an existing backup policy), generating pre-processed container information (where the generating the pre-processed container information comprises performing data pre-processing on the container information), determining a plurality of container ranges for the first one or more containers, generating container range affinity information for the one or more backup images (where the generating the container range affinity information comprises performing a container range operation using the plurality of container ranges, and storing the container range affinity information in a container range data structure.
