From history we know to avoid using Microsoft supplied backups. Maybe some file sync system is what you are looking for? I use any of the following for that.
Roadkil's Unstoppable Copier.
SyncBack (LE?)
I also use FileZilla but how to sync seems to elude some.
in windows 10 how to change to incremental system in back up, so only files can be backed up regular, instead of the whole system
