Abstract: The techniques introduced herein provide for systems and methods for estimating the effectiveness of utilizing a data deduplication process. More specifically, a content-based sampling approach for data deduplication estimation is described in which a subset of the scanned fingerprints of a dataset are included in a content-based sample that is used to determine an accurate deduplication estimate for a dataset (or volume).
