Windows 10: Windows 10 backup not working

I have Windows 10 20H2 (compilation OS 19042.630) and I can't back up to Windows 10. Give me this error without screenshot
I have 3 HDD and a SSD M2.
Disc 0 - HDD Western Digital 1TB a have 5 partition: F G H I J L
Disc 1 - HDD Western Digital 1TB a have one partition: K
Disc 2 - HDD Western Digital 2TB a have one partition: E
Disc 3 - SSD WD Black SN750 500GB a have 2 partition: C (windows) and D
I can't explain how it was done partition System Reserved in Disc 0 and not in Disc 3 (C) where is the windows?
I think that's the problem with not being able to back up. How can I delete System Reserved in Disc 0 and to do it Disc 3?

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK
