Today I'm working on my wiring diagram today (now that I've settled on a mixer), but I'm also thinking about my backup options for my DJ Computer. Since my ONLY computer in my Small System is a Dell Optiplex 7440 AIO computer, there's no built-in backup for it if something catastrophic was to happen. I've been really fortunate that I've never had any kind of failure with this computer, but it's only a matter of time... could be next week; could be 10 years from now. Ya just never know, but (like all machines) it WILL eventually fail. I've been carrying a laptop and my Allen & Heath ZED-10FX as my backup. Nice little setup, but not really a practical for anything except a temporary music source until my main system can be recovered. The laptop doesn't have any DJ software on it; only a music player application. Without having a connection to a controller and Traktor (or some other DJ software), it's just not a REAL backup (if I had to use it for an entire event).
So with that said... what are others using as their backups??? Again, I intend to have a tablet and Bluetooth for an EMERGENCY, temporary, music player. I could install Traktor on my laptop and plug it into my controller in the event of a computer failure. Certainly, this is the most practical backup solution. But what if the controller fails? I've been carrying my Large System's MC6000MK2, but now that's mounted in my Large System, so I won't be carrying it to events where I'm using my Small System. So I'm thinking about one of these...

... I think this will give me a completely separate system that I can plug into the new mixer, or just connect my speakers to it, and I'd still have my ZED-10 to add microphones. There's probably a ZILLION other options???
