>can files be restored directly from copy storage pool volumes...

Tim - Info like that is available in the Admin Guide.  Chapter 8, in talking
      about the Copy Storage Pool:

    The copy storage pool provides a means of recovering from disasters or
    media failures. For example, when a client attempts to retrieve a file and
    the server detects an error in the file copy in the primary storage pool,
    the server marks the file as damaged. At the next attempt to access the
    file, the server obtains the file from a copy storage pool.
