Have nginx for all my reverse proxies, it wasn’t trivial, but I used it for a lot of other things so it’s fine.
I back it up manually to encrypted json, it’s not the right way, but I never had much of a proper backup system, other than zfs snapshots and occasionally mirroring to another zfs pool.
It’s not a lot of extra work once you have the rest of your apps running, it’s fairly low maintenance and mostly just works, but again I haven’t bothered with backups really.
Edit: Running most if not all my services on freebsd as jails, that might have made it easier.
