A recent update broke the file history service for me, which I only discovered when I went to restore a previous version of a file. If you use it too, you should probably check it's actually working.
One recent issue required cloning the user account to get file history working. Just would not work with that account while any new account worked fine.
Current status is broken - the last two security updates report file history as broken. Git hub handles code ok, but for all the other stuff on windows file history was the way to go. Now cumbersome incremental backups.
