For a number of people I know, they don't do any offsite backup of their home media server. It would not result in any possibly-catastrophic personal financial hassles/struggles/real data loss if a bunch of movies and music disappeared overnight.
The amount of personally generated sensitive data that doesn't fit on a laptop's onboard storage (which should all be backed up offsite as well) will usually fit on like a 12TB RAID-1 pair, which is easier to back up than 40TB+ of movies.
Same here, I use raid 1 with offsite backups for my documents and things like family pictures. I don't backup downloaded or ripped movies and TV shows, just redownload or search for the bluray in the attic if needed.
