Probably close to 100% if your house catches on fire.
- briffle 8y agoCame to say the same thing. Or flood, tornado, earthquake, etc...
- Retric 8y agoProbably closer to 10%. House fires rarely completely destroy the house and cars are often somewhere else. Wildfires for example often destroy homes, but generally allow most people to evacuate.
- Something1234 8y agoI have to agree with the guy above. House fires often leave a significant bit of the house structure alone. I also feel that a decent number of scenarios where my house would burn down would be when I'm not there.
- cyphar 8y agoTheir USB drive was plugged into their NAS. The probability (as they found out in TFA) is very high that a power surge will knock out most of their devices. A house fire wouldn't hesitate in destroying both. I think "close to 100%" is being too generous. If you don't have 3 copies of your data (with at least 1 offsite) then your data doesn't really exist.
- fencepost 8y agoThe chances of both failing get even higher when you factor in failure causes like "I was running old firmware and someone's ransomware exploited that."
