I have now installed Bazzite on SSD A and booted successfully. I wish to replicate the entire system using Btrfs RAID1 onto another spare SSD B, enabling SSD B to provide service should SSD A fail. Should I use GRUB2 to install an EFI and EXT4 extended boot partition on SSD B? Or should I simply use `dd` to copy the entire contents of SSD A to SSD B, then configure a Btrfs RAID1 array across the Btrfs partitions on both SSDs?
