    摘要: Mechanisms are provided for improving the efficiency of garbage collection in a deduplication system by intelligently managing storage of deduplication segments. When a duplicate segment is identified, a reference count for an already maintained segment is incremented only if the already maintained segment has the same lifecycle as the identified duplicate segment. In some instances, an already maintained segment is assumed to have the same lifecycle if it is not stale or the age is not significantly different from the age of the newly identified duplicate. If the already maintained segment is has a different lifecycle, the new segment is stored again even though duplicates are already maintained.

    摘要: Mechanisms are provided for optimizing files while allowing application servers access to metadata associated with preoptimized versions of the files. During file optimization involving compression and/or compaction, file metadata changes. In order to allow file optimization in a manner transparent to application servers, the metadata associated with preoptimized versions of the files is maintained in a metadata database as well as in an optimized version of the files themselves.

    摘要: Mechanisms are provided for optimizing multiple files in an efficient format that allows maintenance of the original namespace. Multiple files and associated metadata are written to a suitcase file. The suitcase file includes index information for accessing compressed data associated with compacted files. A hardlink to the suitcase file includes an index number used to access the appropriate index information. A simulated link to a particular file maintains the name of the particular file prior to compaction.
