Abstract
Methods and apparatus are provided for reporting space savings due to pattern matching in storage systems. An exemplary method comprises, when a given allocation unit in a storage system matches one or more predefined patterns, (i) setting a corresponding pattern flag for the given allocation unit, and (ii) incrementing at least one pattern counter; generating at least one snapshot of at least a portion of a file comprising the given allocation unit; and determining a data reduction attributed to pattern matching based on the at least one pattern counter, wherein the one or more predefined patterns in the at least one snapshot are excluded from the data reduction attributed to pattern matching.
