Since moving to a new MBP I am having endless of trouble with TM backups. They practically all fail, at different time points, with different files being the culprits (see below).
I have a WD MyBook Duo, which is an external drive chassi with two bays and some software that allows for running RAID (which was the entire reason for me to buy this device). I have tried to repair, erase and reformat the drive(s) it doesn't help. I have reset the Time Machine prefs and started from scratch, no avail. I have also tried connecting the disk to different USB-C ports (always via an Apple adapter) and even tried to remove all the other cables on the adapter. Still no joy...

The actual files change, probably since the backup failures happen at different time points. As an example here's another chunk out of the logs

I have been all over WD homepage, but nothing useful there either. At this point my working hypothesis is that firmware on the disk cabinet is messed up or incompatible with USB-C somehow because:
- The same disk was working without any hiccups with my 2014 MBP.
- I can use another, stand alone external disk for backing up the new MBP.
but that doesn't really make a lot of sense either.
Any suggestions? What do these specific error codes mean, is there a listing for these perhaps?
