Well, how much money do you want to spend on it?

Let's go all-out for a moment.

1. Dual power supply server, with two indpendent UPS and a
standby generator.

2. RAID-1 or RAID-10 disks to store everything. You double your
storage cost but your data is safe against most disk failures.

3. Hourly rsync of database dump and all recorded files to an
independent NAS, preferably running a different OS from your big
machine. Extra points for having the bandwidth to do this
offsite.

4. Spares, in static-proof, waterproof storage, preferably in a
separate building. Spare components, spare computers, spare
TVs... actually, strike spare TVs. You can reasonably rely on
having a big-box store sell you a TV that isn't quite what you
wanted for too much money when you need it.

5. As many independent program sources as you can arrange: OTA,
cable, satellite, perhaps a second cable source or equivalent if
you live in a place where that's an option.
