===========================================

When I had Backup sync failed.
My backup set was trying to back up System Volume Information

~ my Cloud Backup set tried/failed to back up System Volume Information apparently because I had opted Back up common file types only = off.

System Volume Information folder contains hidden protected operating system files.

I’ve since excluded System Volume Information folder.
