I went to Backup - with an ext. HDD plugged, I added the drive and I was able to turn on File history where it started backing up my files.
I don't normally use that as I used to use the Win 7 system image but as that has been deprecated in 1709, I have changed to using Macrium Reflect Free for my full images.
Can you go Start - type services.msc and press enter then scroll down to File history to check its status - it should be showing as Manual (Trigured)
Event Viewer or reliability history may give you a more accurate error or code as to why yours failed to start.
I haven't Googled that error code yet.
