W10 Pro V2004 backup 'strangeness'.

OK, wife's PC, HUGE back-up, usually takes more than 12 hours... sometime 14 or more. Don't ask...

First time doing under the new Windows version. She normally checks the Shutdown when completed box. Today, PC still on and ATI 2020 says less than 1 minute to go?

Checked her email, got this one first and then 4 dup's:

First one:

Since she 'woke up' the PC and saw these, I looked around. Disk is fine and can be accessed. About 15 minutes later, it FINISHED! Here is the e-mail:

Really ODD... and she was complaining yesterday that it took almost 4 hours CALCULATING the size, and her PC was slow. I did NOTHING to the PC other than open the disk with Explorer?

No changes (that I made or are aware of) to the Power Settings? Display off after 20 minutes of inactivity and disk off 30 minutes after no activity.

Suggestion? I have a program that 'keeps the PC active' that I use for large downloads, should I run something like that? However never needed to before?
