If you are to backup just system together wit C: all you need is C: and two partitions in front of it. Those partitions behind it (Excluding D are probably leftovers from past upgrades. Can't use them anyway.
If you look at my picture, I left only last backup partition and don't use UEFI at all.
I have not verified images in ages, must be years now. Macrium really is so secure, I've had no issues with images. Anyway, I create images so often that a corrupt image is not an issue.
Looking at your screen shot.
You must have done upgrade/in place repair at least 3 times. Each time, Windows will shrink your C partition by 450MB to create a Recovery partition to store WinRE.wim (it is a version of WinPE containing a set of tools for trouble shooting) to boot into the Recovery Environment by hold down SHIFT key+Restart.
To find out which Recovery partition is currently used. Open Admin command prompt and type: reagentc /info
which will point to the partition # containing WinRE.wim.
The 99MB EFI System partition (not 99GB) contains the BCD code for booting Windows. Without it, Windows won't boot.
There's a 16 MB MSR partition between the 99MB partition and C drive hidden from Disk Management but will show in Macrium.
Disk Management also report all 450MB partitions are 100% free because the partitions and files in them are hidden and they are not empty.
If you get rid of those Recovery partitions, Windows will still boot. However, The Recovery Environment will break and I saw quite a few people just deleted all the Recovery partitions and if they have the need to get into the Recovery Environment, they just boot the Win 10 installation disk and click on "Repair My PC".
Below is a screen shot of my current Windows and should only have 1 450MB Recovery and reagentc shows partition 1 containing WinRE.wim
NOTE: To clean up those partitions without breaking anything as posted here:

Posted this note in first post:
I asked mods to move these almost 30 posts about Macrium from TF Video thread here to keep that thread a bit less cluttered, more focused on videos.
