How to image a Debian system on a zfs mirror? (discuss.tchncs.de)

I have set up a refurbished PC as a media PC with storage. The OS, Debian, is on an m.2 nvme disk of 256 GB. I have connected 2x4TB risks in zfs mirror mode to store my media.

Off late, while booting, I've noticed some messages that suggest that the health of nvme disk is not good. Searching the error, i realised that I should not rely on it. I've done a number of tweaks to set up my system the way I like that I want to save by creating an image of the OS drive on a fresh nvme disk of same size that I have.

How do I go about doing it? I could boot using a live USB and create the image on the HDDs but the live USB OS won't recognise my zfs, right? Is using another external disk or another PC my only option here?

Thanks and cheers!

PS: The machine is a HP Elitedesk 800 G3 that has a wifi port that I've heard can be used as additional port for m.2 drives. Is it true?

That depends on your use case, I just did a simple zpool with no redundancy because I wanted maximum speed/capacity and all my data is backed up on an external HDD. If you need redundancy, I would look online for how to configure that and what the optimal setup is.
