Windows 10: Win 10 Win 7 Backup Failure 0x800700E1

Hi,
I am running win 10 pro 64 bit and am using the win 7 backup process. I backup every week and have been doing this for many years (I am a mainframe dinosaur). Last week I started getting this failure just as the backup was ready to finish (during the system image creation phase).
win 10 backup failure 0x800700E1
I have researched it and tried all of the recommended steps (running sfc, DSIM.EXE) to no avail.
My environment is:
Lenovo P70, 64GB RAM
Hard Drive is 1TB partitioned to 3 drives (C,D,E)
Backup is External USB3 Seagate 5TB 1 partition.
I am up to date with Win 10 updates except for 1809 (it keeps failing).
All help and suggestions are appreciated
Maurice

Win 10 Backup problems

More details to report on my previous question about my backup problems using Windows 10.

1. The backup error code I get when doing a backup of my files on my brand new WD External Hard Drive is: 0x800700E1.

2. I disconnected my WD EHD from my Windows 10 computer and connected it to another computer running Windows 7. I ran a backup using this Windows 7 machine and the backup was successful.

3. I disconnected the WD EHD from the Win 7 computer, and reconnected it to my Win 10 machine. I ran a backup again using the Win 10 computer, and the backup was still not successful, with the same error code of 0x800700E1.

It seems then the problem is with Windows 10.

 

How do I solve error code 0x800700E1 backup failure?

Win 7 and Win 10 on network

I have home network with separate modem, router, and WAP's. My Windows 7 computer does NOT list the Windows 10 computers on network computer list but the Windows 10 computers network list DO list the Windows 7 computer.

Turned off firewalls, gave permissions, shared drives. Nothing allows Win 7 computer to access the Win 10 computers.

Any suggestions for a fix?
