Interesting. Is a magnetic event more plausible for you than other types of decay? I'd expect physical damage from something like a flooding to be much more likely than some sort of magnetic interference.
But that probably depends on the location you live in!
- wtetzner 5y agoI think the idea is just to have different kinds of backups that have different failure modes, to make losing everything at once less likely.
- btrettel 5y agoI don't know how likely some sort of electromagnetic event is. I just figure that if I'm going to diversify my backup strategies then something dissimilar/uncorrelated would probably be a better choice. My data is on magnetic hard drives, SSDs, and optical disks, each of which has different risk profiles. As wtetzner said, it's unlikely that a single event could cause all of these to fail. An EMP attack might take out my magnetic hard drives and SSDs but leave the optical disks unaffected. I've also had a hard drive fail due to impact damage that likely would not affect a SSD. Flooding is not something I've thought about before, but since my backups are located in different geographical areas, I should be covered there. Etc.
