Need guidance to configure partitions and Backup/Recovery/Restore devices

I'm having a little trouble following the new format in storage. I have supported windows as a tech since version 2.0 and have many years experience with hardware, software, network admin, troubleshooting and building and repairing PC. but, the changes Iv'e followed through a rapid Deep-End of the Pool to Win8, 2 months ago to 8.1 a few weeks later, then Win 10 3 weeks ago have left my 62 year old head spinning.

I have failed to setup File History and Recovery disks on USB sticks (32G) and SDCards, also 32G, and just exchanged the wrong CD's for the right DVD's to use them as Backup Storage locations,

I had a driver problem on this Toshiba P745-S4320 I bought used a week ago.
So I tried to roll it back to Win8 or 8.1. That was a No-Go, but it at least tried.
So, I opted for the Reset with keeping my files.
That worked fine and succeeded.

Still, I have two drivers issues, I'll get to that later, and that led me to the drives and backup, restore and recovery issues I'd like to understand.

I used Windows Disk Management to learn the following, but am not sure what I learned.
***************************************************************************************************************
On my only drive:
System Reserved, 100MB NTFS, Healthy (System, Active, Primary Partition
AND (C 232.29 GB NTFS, Healthy (Boot, Page File, Crash Dump, Primary Partition)
AND 506 MB, Healthy (Recovery Partition)

C: contains no mysteries, however the other two do.
System Reserved has 4 right-click options;
Change Drive Letters and Paths
Shrink Volume
Properties
Help (which it isn't)

I felt no need to explore the first two, so Properties led me to what little I could learn.
There are 34.1 MB used on this volume, the balance free. So, what are the files taking 34.1 MB's

Are they a factory restore volume I can't figure out how to access, or are they the files Win10 used to restore itself to the day it was installed? If it's the location of Win10 Reset/Refresh files, I'm fine with it, but can't see the need to waste the unused portion of a static storage location.

So, is it ok to shrink the volume by 50 MB and if I do, where will they go? To the 506 MB partition or the C: partition?

Ok, I've been working on this as I've created this post and just learned something. I have a 32G SDCard and got it formatted in a cmd window after finding the format option in Win10 won't format over 32G. Anyway, I went back to the Backup & Restore (Windows 7) in Control Panel, and restarted the Create System Image process, forced it to used the SDCard, but it is only 58.9G and the image needs 79G. But, getting that far answered one of my questions. In the screens it shows what is being backed up in the Image;

System Reserved (System)
(C (System)
Windows Recovery Environment (System)

So, it would seem that the third item is part of all this.
Now, what I would like to know is what is what?

Is it all part of one, and what I've seen is there is no factory partition, or at least I don't know how to get in it, so is it ALL windows reset/refresh to a new install of Win 10, or is it that AND where the restore points are located , which is what seems most like. In other words, the Restore points are in the first, System Reserved, and the Fresh Win10 is in the third, Windows Recovery ???

Until I have an external drive large enough, I'll have to use a DVD for the Image.
Maybe I can get a backup on the 58G SDCard.
I thought I had created a System Repair Disk on the SDCard once, but I couldn't get the machine to boot from it. No, it did not give me errors, I entered the CMOS and changed the Boot order, and hit F12 to enter the boot menu and selected it, but the machine blew on by to the HDD to boot.

I shall persevere and in the end, I shall know.
