Differing kinda of storage in case one doesn’t work with the device being restored to, or something happens that’s more likely to affect one type of media than the other. A strong electrical field could scramble the hell out of spinning rust’s magnetic media, while doing nothing to optical media, for example.
Just realised my primary, backup and offsites are all spinning platter disks. When they say two types of storage, what does that mean exactly?
