Abstract
The present invention is directed toward methods and systems for data de-duplication. More particularly, in various embodiments, the present invention provides systems and methods for data de-duplication that may utilize storage reclamation. In various embodiments, data de-duplication may be performed using data storage reclamation by reconciling a list of all active tags against a list of all tags present within the object store itself. Any tags found to be in the object store that have no corresponding active usage may then be deleted. In some embodiments additional steps may be taken to avoid race conditions in deleting tags that are needed by incoming data. In some embodiments the object store may request the lists. In other embodiments, a runtime list, in which each new tag is entered as they are returned from the object store. In another embodiment the object store may maintain this list directly.
