For the past few days, File History on my Windows 10 Home (20H2) has stopped working.
In Settings, "Back up options" opens after a noticeable delay and displays the size of my back-up as zero bytes with the message' "Your data is not yet backed up".
On clicking "Back up Now", a "Cancel" button appears after a few seconds with no back up having taken place.
On clicking "Advanced options" and clicking on "Run Now", an error message gets displayed, "We can't copy files to your File History Drive; Failed to initiate user data back-up (Error 80070005)".
I had even contacted MS Support (tier 1) and gone through a remote PC access session but the problem persists.
I'd be grateful to receive advice.
