Wishing to replace the system drive with near identical sized new and fresh SSD, or even a larger one, leaves me with a puzzle. dd is great and I can't use that bit-by-bit copy technique f.e. because my source drive died or is unreliable. I have a backup of all the data available.

The issue is how to backup and restore and/or migrate/clone the GPT partitioned drive structure using a script without its files and directories:

  1. partitioning
  2. file systems (and their properties)
  3. swap

A search here for "migrate new drive -lvm" returns 30 results, none of them give me a hint.

Is there some kind of handy scriptable parted --backup and --restore command to accomplish this task in a minimal Arch Linux installation, that is UEFI booted?

You can find many ways to copy the partition table here: How to copy the partition layout of a whole disk using standard tools

After that you still need to format each partition with its specific filesystem type. You can surely automate that part from the partition list, however I doubt I would be worthwhile as there are some options you might need/want at filesystem creation that you can not derive from current ones (or you are just taking the opportunity of a new disk to format things with new options)

To copy and restore a partition table you can use fdisk. Make sure you're using a modern version of fdisk though. That should be the case on an up to date Arch Linux fdisk.

fdisk /dev/disk/by-id/bus-model

O

partitions.txt

Then to load it back

fdisk /dev/disk/by-id/bus-model

I

partitions.txt
