Who are we?
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). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
We are one. We are legion. And we're trying really hard not to forget.

Running 2 redundant unRAID systems which mirror ZFS snapshots between systems. The main system(150TB) is the one that has all of the SMB connections to the rest of the network and allows modifications to the filesystem (with a valid login). The backup system has no public shares and exists only to replicate the main system and is just large enough to store personal documents and such.
For critical data (read: personal documents, family photos, etc), in addition to the backup server, I also keep an 8TB drive in a safe deposit box, and I bring it home about every 6 months to rsync all of the latest updates to it from the backup server.
For media (TV shows, Movies, music), it's only "protected" against failure with unRAID's array system with dual parity. I don't bother with backups at all, because it's very large, and all easily replaceable.
