Perhaps I should mention the old adage that plumbers homes tend to have terrible pipes? :-)
We don't have a real failover system, primarily because setting up and maintaining a true failover system is harder when the system is database backed (like ardupilot.com is). It can be done, but it is more complex. Right now I'm erring on the side of simplicity rather than minimising the risk of downtime. I am doing some work at the moment to improve the robustness of the system, but I don't think I'll switch over to a fully redundent hot failover system. I have run systems like that before so I'm very familiar with what is involved and for the moment I don't think it is a good use of our time to work on that.
@Bill. My apologies for being a bit cheeky. The point I was trying to make is that those who are keeping things running around here are highly qualified and certainly are well educated in backup systems. People like Rob, Tridge, Jonathan, Randy, the mods etc (apologies to those not mentioned) would rarely mention how much talent is here. Software engineers, aerospace engineers you name it. Can't swing a cat around here without hitting an engineer. It actually is rocket science by rocket scientists. :-)
Hi Darrell, I don't know who the author is. I was just using that as example. I'm sure there are many solutions for a redundant server setup. Probably the easiest would be to use a hosting service that has redundancy and power back up.

I appreciate you guys and all your work.
Happy Holidays

Thanks for setting me straight Rob.
Should have read closer, it appears that rsync is an optimized backup system rather than redundant.
Bill, Tridge wrote rsync. ;)

@Bill Isenberger - I noticed that your recommendation for a fail safe uses rsync. Guess who the author of rsync is?
Might be good to set up a fail safe for your server.

Thank you for all of your hard work, this project has been so successful because of the attention to detail.
+Tridge, I applaud you for keeping up on your backups.
