There's a (I don't know whether to call it a fallacy, but I will)...there's a fallacy that Jumbo Jets are safer than automobiles. This assertion is easily derived from looking at death statistics from each vehicle. But then, such statistics involve random parties. You or I aren't random drivers and so we may be very safe or very dangerous on the road [1].
Anyway, the average person's data is much more likely to disappear than that on google's server clusters. But if you are diligent, you can have backups that work 99.9999999 percent of the time quite easily.
[1] Of course, on roads, the guy driving in the other lane is pseudo-random, so... But there is no other lane with computers.
- edw519 19y agoI am ALWAYS concerned about this (some may call it fanatic). I back up everything twice every night. Hit the safe deposit box once a week. Always have one thumb drive with me, another hidden. Print hard copies of recently changed code. What if I have a break-in? What about a fire? How about lightning? (Already lost 2 servers that were protected - it happens.) What about a flood? Sometimes I wonder why I don't just store everything on the "cloud". One of these days...
- mynameishere 19y agoPrint hard copies of recently changed code. Okay, that's nuts. ;) Source code shouldn't be a problem. It practically backs itself up: 1) Production server(s), 2) Test server(s), 3) Development server(s), 4) Source control server.
- edw519 19y ago"It practically backs itself up" I'll rank that up there with "Step on it! We're only doing 90!" as famous last words.
- cstejerean 19y agoEither your code is REALLY valuable or you are really paranoid (and either way this might be a sign that you have too much free time).
- cstejerean 19y agoA bit to many 9's. 99.9999999 uptime means a downtime of less than a second per year. If my calculations are at least close it's about 1 second downtime during a period of approximately 30 years. As far as cars go, I remember reading something about 80% of the people thinking they are above average drivers.
- mynameishere 19y agoNot talking uptime/downtime but just the ability to restore lost data. If I have 3 backups, what are the odds that all three will fail at the same time as the source (assuming different locations, which is the case with my own system.)
