Abstract
Embodiments are directed to methods and apparatus for making available to at least one scanning tool, information about at least one data unit shared among multiple storage objects of a plurality of storage objects stored on a storage system. The at least one scanning tool can use the information to influence at least one scanning operation on the at least some of the plurality of storage objects. Embodiments may be implemented in a computer system comprising at least one application program, at least one mapping layer that makes available to the at least one application program a plurality of storage objects, and a storage system that stores data in each of the plurality of storage objects in one or more data units. The at least one computer system further comprises the at least one scanning tool that performs the at least one scanning operation on at least some of the plurality of storage objects, and at least one redundant data elimination tool that eliminates at least some redundant data by sharing at least one of the data units among multiple storage objects.
