Ok , I Restarted the iPad 10, opened stagetraxx , whilst in stagetraxx , went to settings/show files, then looked at info .
It States 512 items 13.9gb. ?
There are x97 pdf files / x3 back up ***.st3 files each approx 2gb / x 412 stereo mp3 files ?
Question : When you perform a full back does it also save any previous .st3 back up files, if they are different names of course.
If it does, then in my case ,the next back up should be 6gb + , is that correct ?
Hope this makes sense , thanks
