Boot from ArchLinux ISO Make sure we have enough space for installing needed packages, etc: Establish repos and update keyring: Add the archzfs repo: Get keys sorted: Adde the ArchLinux archives to get the correct kernel and headers to match the booted ArchISO Now install the matching headers to the version of the kernel running while booted from the ArchISO – Note: you can leave out linux if you want, but it prevents an error during dkms installation – the error does not prevent loading of the zfs module: And install the zfs-dkms package from ArchZFS repo and other required packages: Load the zfs module – if you left out the linux package, updating linux initcpios will fail, but the module should still load: Now we can mount the existing pool and backup: For making a copy of qcow2, cleans up churn growth: I have a ZFS pool named “storage” I back up my NVMe drive to.
