I wanted a backup of its OS so made a backup of the whole partition 57GB so now have it as a img file and its now on my One Drive like my ARMIGAOS is so I never lose it because things can go wrong and its always good to have a full back of them.. .

I know I could of used the backup option in the A600 GS Menu but I think that makes a back on its partition so you lose it if the whole system stopped booting.
Its the first thing you should do make a copy of its sdcard, and save it on your PC.
I have the A600 GS OS now on 2 SD cards, I realised I already had the same SD Card(Kington) and its 64GB too so that was handy....

does not hurt to have copies of it.
