Abstract
A system and method for improving performance within a storage system employing deduplication techniques using address manipulation are disclosed. A data segment within a storage object is identified from among a number of data segments within a storage object. The data segment represents data stored in a storage device. Some or all of the data represented by the data segment is stored in a data block that is associated with the data segment. The storage object is then compacted. Compaction includes reordering data segments, including the identified data segment, by performing address manipulation on a data block address of the data block (e.g., an address of the data block within the storage device). The reordering of the data segments changes the order of the data segments within the storage object.
