Abstract
Methods and apparatus for organizing a plurality of versions of a file in a file system. The plurality of versions of the file are stored in a data structure having a hierarchical organization that reflects relationships among the plurality of versions. Each version of the plurality of versions is assigned a name that identifies its position in the hierarchical organization. The hierarchical organization of the data structure and the descriptive naming convention used for the plurality of versions in the data structure facilitates deleting a version while retaining other versions derived from the version following the deletion of the version, and enables a staged initialization of the data structure upon system start-up.
