Abstract
Apparatus for managing a plurality of root nodes may include a file server coupled to a storage device, wherein a first root node is operable to identify a previous version of an object of a file system and to relate to a plurality of data blocks forming a portion of the object, a second root node is operable to identify a current version of the object and to relate to a data block of the plurality of data blocks and a new data block of the object, and the storage device is operable to store the plurality of data blocks and the new data block. Apparatus for managing a plurality of root nodes alternatively may include a file system board operable to manage a plurality of root nodes, a first root node being operable to identify the a previous version of a file system and to relate to a plurality of data blocks of the file system, and a second root node being operable to identify the a current version of the file system and to relate to a data block of the plurality of data blocks and a new data block of the file system.
