Syntax:

      /[NO]STAGE

  Use /STAGE to withhold committing changes in the CDD until the entire
  restoration is completed.  Use /NOSTAGE to make changes in the CDD as
  each dictionary directory,  subdictionary,  or  object  is  restored.
  /NOSTAGE is the default.

  Using /STAGE assures that no changes remain in the  dictionary  if  a
  command   is  interrupted.   However,  with  /STAGE,  execution  time
  increases   exponentially   with   the   number    of    directories,
  subdictionaries, and objects restored.

  With /NOSTAGE, execution time increases linearly with the  number  of
  directories,  subdictionaries,  or objects restored.  However, if you
  interrupt an unstaged RESTORE command, some of the changes remain  in
  the dictionary.
