If so I will write I don't count on Windows Backup for backup or restore. It's been too unreliable. What works for me is a clone of the OS drive and for data any "SYNC" app like Roadkil's Unstoppable Copier.
After so many Windows Backup failures, my answer is it doesn't work.
I'm running 8.1
I have an "E" drive that is supposed to provide a place to back-up data. How do I know it's actually working? The file data date is 8/15/18, which is the date I told it to set up the regular windows back up. The disk is about 1/3 full, which doesn't really tell me anything. I've tried to open the files to see if there are any later dates or to see if there is any data, but can't find any data I recognize or any later dates.
Is this really backing up my data?
