System and method for scalable reference management in a deduplication based storage system
Abstract:
A system and method for managing a resource reclamation reference list at a coarse level. A storage device is configured to store a plurality of storage objects in a plurality of storage containers, each of said storage containers being configured to store a plurality of said storage objects. A storage container reference list is maintained, wherein for each of the storage containers the storage container reference list identifies which files of a plurality of files reference a storage object within a given storage container. In response to detecting deletion of a given file that references an object within a particular storage container of the storage containers, a server is configured to update the storage container reference list by removing from the storage container reference list an identification of the given file. A reference list associating segment objects with files that reference those segment objects may not be updated response to the deletion.
