I was just thinking about this recently. For my original data I already have multiple copies: 2 desktop PCs, home and office, synced with a home NAS, adding a server in the office soon too, laptop has everything but photos (which is a lot since I am into photography and timelapses). My non original media has only one copy, but will soon have a second copy in the server at my office.

But I can't count on using my office at my job as a long term thing. For my original data, I have been planning on getting something like Backblaze for a full professional off-site copy. For all my non original media, well... It would be ok to lose it I suppose, but I would rather not. Would this be a good use case for some sort of other stable media? I forgot what it was called, but I recently saw a post about some high density disk (like some sort of multi TB blu ray disk thing?) That seems like a decent solution, better to lose 1 year of piracy instead of 20 years of piracy haha. I have lots of obscure stuff that would be hard to get again, curated by and copied from cinephile and audiophile friends, rare movies I ripped from university library DVD discs and even VHS tapes!

Maybe I need to start learning about some alternative storage media for that stuff. Anyone have suggestions? Some sort of tape or disc for this kind of large but immutable media?
