Alright so I'm both a physical media freak and a data hoarder, and I generally want to get into making my own torrents of very, very niche movies and TV shows. Trouble is, one BD is very flimsy and data can be even flimsier. I want to duplicate my BluRays and burn them onto other BluRay discs but I've heard that this generally makes the duplicate unreadable because of copy protection.

Is there any specific guide out there that does this or teaches it? I'm not really planning on becoming a bootlegger but a sneakernet of 50-100 disks in boxes is a hell of a lot less startup cost than LTO or even HDDs

I use BD to archive personal data. Then send it off site. The data is encrypted, so it can only be accessed with the correct authentication. What's wrong with that?

Nothing really, but the lifespan of burned BD’s could mean you don’t have access to your data in the future.

if I outlive an m-disc I probably didn't need the data on it anyway

That’s fair for sure.

Compared to what? I mechanical drive left on the shelf tends to seize up over time. Flash storage looses it's trapped electrons representing bits. To protect the more sensitive data from bit rot, I use par2 for the files and dvdisaster for the whole disc.

That works too. I guess compared to a drive in a NAS, which had its own parity and aren’t sitting stationary on a shelf, that are replaced as they start reporting SMART failures or whatever.
