Sounds like the "or such" wins, but even with bluetooth speeds that means you're backing up 1-5 photos per minute and that helps a lot.
And harm a lot too, you phone can't deep sleep since it has to wake up periodically to process data from bluetooth stack. Combined with slow transfer speed, that gonna eat your battery like nothing.
