Backing up user directory (selected) files
    To back up all files in your user account, including directories and
    subdirectories, perform the following steps:
    1.  Choose "Save Selected Files ..." from the File menu and choose
        "Save selected files as a snapshot image" from the list box.
        Note that you will not be able to perform incremental backup
        operations with a snapshot image.  If you want to perform
        subsequent incremental operations, choose "Save selected files
        as a baseline for incremental backups".
    2.  Fill in the field values on the Save Selected Files screen.
        For example:
        Input
         Device Name         : USERS$DISK
         Files to Save       : USERS$DISK:[SMITH...]*.*
        Output
         Save Set Device Name: MUA0:
         Save Set File Name  : SMITH.BCK
        Miscellaneous
         Tape Label(s)       : SMITH
         Listing File Name   : SMITH.LIS
         Save Set Comment    : Smith account files baseline backup
    3.  Choose any options you want from the Options menu.
    4.  Press PF4 or choose "Start Operation" from the File menu.
