Data Hoarder

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.

The 3-2-1 rule (alien.top)

I've always heard that you folks like to keep tons of backups of your stuff. I have also heard that there is this 3-2-1 rule about keeping you backups. My question is: do you follow it personally or is it something that people just tell you to follow?

The 2 in this rule isn’t clear: 2 different media?

Why is it important if it’s DVD & HDD or SSD & HDD?

For home use, it's just two different devices that can be the same type, like harddrives in two servers, but not redundant data storage in one device, like RAID or just having two copies of files on the same drive. For corporate, most will probably interpret it as two different media types, like harddrive and tape. You want them seperate to prevent accidental deletion of files, ransomware and such.
