Abstract
A deduplication storage system with snapshot and clone capability includes storing logical pointer objects and organizing a first set of the logical pointer objects into a hierarchical structure. A second set of the logical pointer objects may be associated with corresponding logical data blocks of a client data object. The second set of the logical pointer objects may point to physical data blocks having deduplicated data that comprise data of the corresponding logical data blocks. Some of the logical pointer objects in the first set may point to the logical pointer objects in the second set, so that the hierarchical structure represents the client data object. A root of the hierarchical structure may be associated with the client data object. A snapshot or clone may be created by making a copy of the root and associating the copied root with the snapshot or clone.
