What is the best way to backup a complete disk on a low level?
On Linux you use something like dd to create a complete image of the disk. Ideally not from within the running system but when booted from another OS.
The problem with the M1 devices is the SSD is soldered to the board and it is encrypted.
Could the whole system be backed up to an external disk while the system is running with dd? The image should be encrypted but can you decrypt it? I think normally you would need a key in the Secure Enclave but when you have enabled FileVault you only the password which is normally asked during startup??
When the MacBook is booted from external media (like from Linux or another MacOS installation on USB) can you back up the internal disk?
Also, there are some tutorials for installing MacOS on external SSDs. Is the disk in these cases encrypted and does booting from external media interfere with the OS security?
