Described is a storage reports duplicate file detector that operates by receiving file records during a first scan of file system metadata. The detector computes a hash based on attributes in the record, and maintains the hash value in association with information that indicates whether a hash value corresponds to more than one file. In one implementation, the information corresponds to the amount of space wasted by duplication. The information is used to determine which hash values correspond to groups of potentially duplicate files, and eliminate non-duplicates. A second scan locates file information for each of the potentially duplicate files, and the file information is then used to determine which groups of potentially duplicate files are actually duplicate files.
