Mojave time machine back up failing

Since installing 10.14 have not been able to complete a full backup using time machine to external drive. All disks check out on disk utility first aid both under OS and stand alone utility under recovery. Have erased and reformatted the external drive. Still no success. Backup begins and runs up to about 80GB ok, then fails. Restart by "back up now" continues for about 500MB and then fails again. My full backup is about 900GB so I am running unprotected.

I believe this is a Mojave problem, not a drive problem.

Any ideas?

Mac mini, macOS Mojave (10.14), Samsung display
