There's nothing built into the product to do what you want, no. You can, if you like, create a scheduled task on the server that uses the same techniques as BDBB to copy the backup database to external storage (those techniques are detailed in
this white paper), and for the shares you can also use a scheduled task to copy from
\\localhost\sharename to the backup device(s). In both cases you will probably want to use some tool more robust than the DOS copy or xcopy commands; I use robocopy for all such tasks. :)
I'm not on the WHS team, I just post a lot. :)
