Abstract
A storage system () stores metadata using an append log to provide speed and reliability. Appending entities to the end of a metadata store () and provides reliability in the event of failure because a failed append operation at worst corrupts the end of the append log, which is easily detected and corrected. A metadata store () can be split into sections (). A used section () may be identified as garbage when the stored metadata in other sections () make the all of its stored entity sets stale. A used section () can be made garbage by storing the entity sets from the section () in another section (). Sections () containing garbage thereby change to unused allow replacement and removal of previous sections () of metadata.
