System and method for efficiently locating and processing data on a deduplication storage system

A system and method for efficiently locating and processing data on a deduplication storage system are provided. A logical volume is mapped to a deduplication storage area. The logical volume includes a collection of logical block locations and the deduplication storage area includes a collection of physical block locations. The collection of logical block locations is mapped to the collection of physical block locations. A filesystem organizes the logical volume by organizing the logical block locations into a collection of files. Reverse-mapping information is generated for a logical block location that associates the logical block location with at least one file. In response to receiving a logical block address of a logical block location, at least one file is returned.
