Hey, I don't know if this can help, maybe not in your case because you are not rooted but I telling you what happened today to me.
I had saved all the folders with obb file of all my games time ago. Every time when I install again the game I just put back the folder and I do the installation. If you do a fresh installation probably your Game Progress will be gone, but I had a Backup of my System Partition, I restored my Partition today with a Backup from last week, so I do not care if I was losing my Game Progress so I just copied again all my folders, started the Game, the Game did his installation and you want to know, my Game Progress was still there.
So maybe if you save the Android>obb folders on SD, then Backup the System Partition with PC Companion, then do what you have to do, Restore the Backup, which will be without obb folders, then you copy back in place the obb folders which you saved before, I think you will not lose your Game Progress and this is the way to backup all data.
I hope this can be helpful to you in some way.
