From my 'help wbak' (at 10.2) command --
|     10.0;wbak (write_backup), revision 1.0, 88/04/15
|     wbak (write_backup) - create a magnetic media backup file
|     usage: wbak -f fileno [-dev | m[unit] | f | ct]
|                 [-full|-incr|-af dtm|-bef dtm]
|                 [-fid id] [-own id] [-vid vol_id]

|     DESCRIPTION
|          wbak  writes  one  or  more  objects  to  either a removable media, disk
|          file or standard output.  ....
|          .
|          .
|          .
|     
|     OPTIONS
|          .
|          .
|          .
|     Backup Device Control
|          -to filename   Backup output is written to the specified streams object
|                         rather than removable media. This can then be restored
|                         using the -from option in rbak. If the file already
|                         exists, use the -r option to replace it.  If -type option
|                         is not specified the file will be assigned the default
|                         type. You cannot use the -file n option with streams.
|     
|          -type [uasc | unstruct | hdru]
|                         Specify the type of the object filename. It can be one of
|                         ASCII (uasc), Unstructured (unstruct) or Streams header-
|                         undefined (hdru) type.
|     
|          -r             If the object specified  with the -to option already
|                         exists, this option allows it to be replaced. The type of
|                         filename is however left unchanged.
|     
|          -stdout        The backup output is written to standard output.

If your Sun's floptical is NFS-mounted (and NFS is working :-) you should be able
to just
    wbak //apollonode/backup-pathname -to /NFSmountpt/floptical/apollo.90.12.06.wbak
If it isn't NFS-mounted, you'll need to pipe stuff around
    wbak //apollonode/backup-pathname -stdout | rsh sunhost <command>
and I'm not sure on the rsh syntax etc etc etc.

Have fun
