It appears to me that when you use the Windows 7 Backup & Restore method, you are creating a system image backup which is different than selecting Backup Now.
When you create a system image backup, you should see a WindowsImageBackup folder on your external HDD.
If you leave the WindowsImageBackup folder as is, I believe it's overwritten (not deleted) each time a system image backup is created.
I say "as is" because some people rename the WindowsImageBackup folder which is another story.
--- Please let us know whether or not you are leaving that file name as is or renaming it.
On the "never backup up" message, if you are not clicking on Backup Now but are creating only system image backups, you will get that message. I haven't used the Windows 7 Backup & Restore method for quite a while, but I if I recall correctly when the "Backup Now" is clicked, you will end up with an additional folder on the external HDD. That additional folder will have an icon with your user name but I don't recall the title that goes with it but that's where the data is backed up.
--- See if you have that additional folder on your external HDD.
On the disk space usage, that needs further explanation based on what's going on.
Do you always leave your external HDD connected?
Are your system images created using a schedule or are you creating them manually?
Thanks for the feedback.
'backup now' has never been used, and with your explanation, it would make sense in that case.
it is creating a system image, on schedule, which is daily, and the folder is 'by default'.
I was under the impression, it was being backed up as a system image, and the changes, were
being updated to that image, not that it would be deleted an recreated.
The EXT HDD is always connected.
Also, "file history" is being used, to that same EXT HDD
That same EXT HDD, is also shared on the Network, and there is a shared folder on there
for another user, who also has Windows 10, Using Windows 7 Backup and Restore, which
is backing up into that folder.
I'll need to check on that computer, and see how it "appears" to be running for comparison.
Thanks again, let me know if you have any other thoughts
