A couple thoughts on places to look for ideas, places where people have probably been thinking about similar challenges:

Interstellar Travel There's a lot of speculation about feasibility here, and I think people generally assume the need for some sort of long-term, low-power cryogenic preservation. They do assume access to interstellar vacuum, though.
DNA "arks" and similar biodiversity libraries. I haven't heard of anything in this space looking at zero- or low-maintenance preservation, but maybe there's a paranoid fringe?

I think GreenRoot refers to the situation where this isn't available, or they wouldn't have to worry about cryogenic preservation.

I understand. I was thinking

How would you prevent solar radiation from heating it up?

..but I'm misjudging relative distances? That is, a spaceship wouldn't spend sufficient time near stars?
