We had a repair man in a while ago that cautioned us not to run the dishwasher when we weren't home or asleep incase it ever started leaking. He said he's been to a few flooded out kitchens because people weren't there to notice it and the water just keeps running. We used to start it before leaving for work. Now, we have switched to evenings while we are home. Sometimes we have dinner dishes in the sink but they get loaded in the next day. The guy has us paranoid..
I think by that theory you'd never leave the house, just in case there was an electrical fault or a drip from a pipe you'd not seen, just in case that tree or perhaps ...
I could tell you about the countless people I have recovered data for after a hard drive had failed. How grateful they were, or how sad that the photos from xyz holiday were too badly corrupted to save, but I was able to pull some photos off the SD card even though it had been erased to make note space for new.
I could also tell you tell you how many of those had backup hard drives to back up data to and hadn't. I could tell you about the ones who diligently save their precious photos to FB and are now locked out of Facebook and have had to make new accounts and say goodbye to that data....
Would it actually get you to backup your data to both an external, unconnected, isolated hard drive and to dedicated cloud storage just in case your device is damaged in a house fire, or flood, or suffers its own mishap? Unlikely unless you know someone who has lost data, which is how almost all of those people found me in the first place, word of mouth after suffering data loss.
Do I backup my data to both a totally isolated external hard drive, kept in a fireproof safe and to the cloud just in case? Yes. I do. I've had a heath fire in the UK get to within 25 meters of our house. Cloud storage wasn't an option then, so a second backup was kept in my locked drawers at work. Would my paranoia get you to back up your data in 2 locations? Probably not get it is even more important now than ever.
And yes, I still set the washing machine to run at night. Yes, I still have a fire proof safe, and yes, I pay for extra cloud storage for that second backup location.
