HTC One M9 – how does Backup / Restore on Android 6.0

I have under Settings, Secure & Reset to default "My Data Secure" set to ON (several months ago)
and would now expect under "restore backup from HTC" to which I could access different backup spots are displayed. But is there "no". "apply anything on this phone" displayed.

I understand the possibility of restoration wrong?

When I sign in to my Google Drive, 321 MB for Drive are reportedly occupied and 921 MB for GMail, but I see only one file (1 MB).

How do I save the settings on my HTC One M9 correctly, so I can also restore?
