Installing on USB

[Rindoza]

What steps should be taken if I want to run Proxmox on a USB? I want to know specifically what must be disabled or configured as to remove all excessive read and write operations from the disk Proxmox is on.
As a background, this is for a home lab, single node, not always on.
I don't care about HA, I don't care about logs, I don't really care about anything except being able to reliably run two windows VMs on the machine.
Top priority is minimizing wear on components for unwanted reads and writes.
I will only need to configure this one time, and I presume I can just backup that config to another $6 usb stick for piece of mind.

As far as I know it is impossible to to that. You can move logs and rrd metrics to a ram disk but proxmox needs to write the config file every minute even if you aren't using HA.
Why don't you use a USB-to-M.2-SSD adapter, a industry USB stick or a USB DOM? That way you get a durable usb flash storage that has no problems surviving the writes.

Maybe this is interesting for you:

Sounds like the backup process is the main reason to need a backup. Not a great implementation, someone should fix this. I have a small enclosure so space is at a premium.
