Venue 8 Pro - Recovery disc creation impossible without USB or Burner - huh?

Prehaps I'm missing something, but after unpackaging my DV8 Pro, I attemped to create the backup/recovery discs.   Software loads fine, but the only options it gives are to USB or DVD Burner - neither are included in the tablet specs.

Plug in a USB drive?  think again - the USB jack is micro, and needs and an OTG cable.    Why wasn't this OTG cable included, at least then I'd be able to use a thumbdrive.

So while I wait for my OTG to arrive, am I missing something - is there another way or option (over WIFI to my desktop ???)   Simularly, the DV8 Pro comes with a CD (MS office Student?) how do I load that into the tablet?

Was going to buy a portable DVD burner, but then I was told the DV8 Pro USB port - even with an OTG cable wont power some devices like external HDD's and Burners.  

Love the tablet, but the getting data in / data out to another device is awkward!

Suggestions?
