Daily updates with rolling distro may cause issues but a stable system that wasn’t tinkered with would run and run and run. Our Linux fileserver at work had a 2 year uptime, only broke that for some drive additions and other adjustments, otherwise it would have just kept on chugging along without interaction. My debian ARM NAS runs without incident, the only shutdowns it sees are when I move equipment to different rooms or want to reroute power cables. Otherwise it would just always be working fine.
