I’ve noticed that it works for me without a login at my home, but it forces a login at my parent’s house. I think its regional or being A/B rolled out or something.
Diggy diggy hole.
I’ve done similar things with ssh pipe tunneling and dd ala:
, dd if=/dev/sda | ssh user@host “dd of=/some/other/file/or/disk” ,
Should really do it while the root is ro, but in a pinch this will mostly be ok on a quiet machine.
You might be able to run rsync afterwards to spot check if you are paranoid.
If you didn’t need block level I would have suggested just using rsync or rclone.
Modern windows 2000 please.
