Thanks. I’ll stick with dd
then. You are correct, I think. I plan to dd
the whole disk. The plan is:
dd if=/dev/nvme0n1 of=/dev/sdb bs=4M status=progress oflag=sync
unless that's the wrong idea. once the usb ssd is done I will definitely check the luks container on the ssd. Size and data availability.
It is lvm2. Thank you for the recommendation! I'll check it out though I think I'm going to stick to the CLI for this one. I kind of want to do it manually.
I do plan to work from a bootsble USB for all the
dd
work so that nothing is mounted/in use.
