dfu_upload error -84 when trying to backup images

[Russell Sears]

I tried this once and got the same error.

Then I ran grep on the image file it produced with words that I knew 
were present in the filesystem like "headphone" "mono" and "state".  I 
couldn't find any words in the image, so I don't think the files it 
produces contain real data.  It could be that it's doing something very 
strange, like flipping bits or re-encoding blocks in the dump file. 
Since upload is known to be broken, I didn't look into it any further:
