After Windows 10 version 1809 update Build 17763.1, my Backup and Recovery now shows error 0x80070013 and will not backup as before

After 1809 update, my external USB drive is no longer listed as "usable drive". I am not able to turn File History on.

That should have worked, in 1809 as in all prior versions. And it really should require no fiddling with OneDrive, either.

(1) I want to suggest an over-install (repair-install) of 1809; however, MSFT has not yet rereleased 1809 to do it with. Its second coming supposedly is immanent, though, & will be here when this site again says "October 2018" (instead of "April", which is 1803)…

Download Windows 10 --  currently says "April" - wait for "October"

Then, do the repair-install as described in here...

How to Do a Repair Install of Windows 10 with an In-place Upgrade

(2) As someone else in this thread has done, switch at least temporarily to a 3rd-party image maker. If your external HDD is a Seagate or Maxtor, there is a free version of Acronis True Image at their site (which only work on their HDD). Seagate calls it DiscWizard. It is quicker, makes more compact images, & is more versatile in use. Macrium Reflect, AOMEI Backupper, & others also offer free versions.

That is the route I took.

RoddyS,

Many thanks for your help.

I've tried the old way to a brand new external disk - 0X80070013 again.

I hope Microsoft resolve the problem with OneDrive soonest.

( I did try a System image to my old external hard disk but that failed after completing the backup of the RECOVERY Disk after 98% of the total backup).

I'll try your version of effectively switching off OneDrive when I get a chance.

I tried again tonight by making my own selection. 

All users ticked.

C: drive ticked

D: drive recovery ticked.

Alas this did not work either. still getting error 0x8007013 after 97% 

Any simple solution ?
