I am not exactly well versed in the ways of backing up an entire Arch install and was hoping you wonderful folks here could help.

Background info:

So I installed Arch on my Lenovo Yoga 7i, after a bunch of mishaps, so that prompted me to want to create a backup image of my machine

So far I have arch with kde setup, Snapper and automatic snapshots for when installing and upgrading, and I have them accessible in my grub menu for recovery that way.

I am mildly a data hoarder I suppose, so I have tons of space.

What I am looking for is a way to backup the entire disk as an image. I have made an image with DD and a live distro.

Though I'm not 100% confident it would be an adequate full backup.

How do you all recommend making an entire system backup? Bonus points for being able to live boot it for testing

Any suggestions?
