We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
That is why you want to have backups. You have learnt it the hard way, you obviously not the one who had this issue. I believe almost everyone in a such way got his lesson.
The most cost-efficient backups are still depending on the amount of storage. As for me, it can be external drive/backup NAS and cloud.
