Back Failed ... but it worked if I ran it again ... failed again today.
I have a few backups running ... this one writes to a SSD (1GB) that is mirrored to my MS OneDrive.
Hmm ... code and spoiler don't work :( ... makes for a very long and generally boring post.
Attached is the results from VVS Doctor.

Thanks. I will follow up on those links.
Same happened again today ... scheduled task failed, manually started task completed.
I found that the Volume Shadow Copy service was NOT started. Have set it to automatic and started it. Will wait until the next scheduled backup (Tomorrow at 3pm) and see how we go.
Update: Today's 3pm scheduled backup went off without any issues.
Thanks to Steve for the solution :)
