[SOLVED] Windows 10 backup not working

[Detonate12]

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?

You can't delete System reserved partition. Bootloader lives there.
If you delete it, your system becomes unbootable.

3. Use a third-party backup tool.
4. Delete EFI System Partition and Recovery Partition.
5. Turn on System Protection.

7. Change the Disk Space Usage.

Generally, when one copies the FULL TEXT from somewhere else, it is customary to give a link to that site.

Delete EFI System Partition and Recovery Partition.​

BTW -there is no EFI System partition in Disk Management screenshot provided above.

And most important - deleting EFI system partition (if there is one), makes system unbootable.
Stupid suggestion (also harmful).

I disconnected the 3 HDDs, left only the M2, reinstalled Windows again and got rid of all the problems. Then I reconnected the 3 HDDs and everything is perfect! Thank you all for your advice.

You could just delete 498MB recovery partition on nvme drive,
create new bootloader partition there and
avoid reinstall.
