Not specifically Archlinux, but I am using Archlinux on my laptop, so I thought I’ll ask here.

I am planing to replace my 1 TB M.2 SSD in my laptop with a 2 TB M.2 SSD, and I am wondering how to clone the whole 1 TB SSD and restore it onto the 2 TB M.2 SSD.

I have read about people using $dd for that, but I never did that. Can anybody confirm that this is possible?

I am running two partitions, one boot and the other one is a crypt device with btrfs + subvolumes inside.

Is there anything I have to consider, before doing this?

Thank you for your time.

    Can you clone from the nvme to the external drive then clone the external drive over to the new nvme once installed? If you have other stuff on the disk you can clone to a file but it will be a slower process:

    dd if=/dev/sdX conv=sync,noerror bs=64K | gzip -c > /path/to/my-disk.image.gz

      Thank you, I ordered a USB case for my new m.2 now :)
