How about buying (and installing) two cheap laptops, say used Thinkpads (or Framework!?), and then backing up $HOME (and maybe list of installed packages) at one's convenience? These are nowadays light enough to carry around when traveling with luggage. If deemed too heavy, at least a Thinkpad likely is on sale closeby and `dd`ing an ISO image, installing the missing packages and copying $HOME should not take too long.

A bit annoying to lug around for a nomad. I'm in a similar situation where I travel a lot with my mac laptop. For me, the ease of just going to a store and buying one if my current fails me is all that matters.
