The most hardcore version is something like this: Nicolas and NixOS
Taken to an extreme: I can take my Laptop, completely wipe its state or replace its disks with new disks, deploy again the OS configuration to this fresh hardware, and I will obtain an identical system.
All your home devices (NAS, desktop, etc) can be rebuilt from scratch automatically.
Until your automation platform (Git, Ansible, etc.) hits the fan, you would in theory need a second build pipeline infrastructure for redundancy purposes, which would require separate storage in a different location aswell. You see where this is going 
, your only limit is how much lifetime you want to spend on such setups.
TL:DR If you want to automate everything the automation has to be redundant aswell, not only the data.
I just backup all my LXC containers completely, doesnât take up a lot of space. I keep daily backups for 7 days, weekly for 4 weeks, monthly for 12 months and yearly forever, everything fully automatic. All the configuration is on the LXCs. Rebuilding from a backup is done in a matter of minutes and I test backups from time to time.
Time to shrink your digital life.
Not mustachian neither in budget, minimalism, time consumed.
Unless thatâs a hobby, which it probably is.
Whatâs your data anyway? Paperwork, thatâs not many GB, if any, even over a whole life. And you donât need to keep it all forever. I would not bother with a NAS and IT management for this use case. If you donât want to give away control over it and keep your privacy, encrypt with your own keys at multiple cloud providers (if youâre paranoid). Store your keys in a safe, or multiple ones.
Photos, unless you do very private and/or precious stuff, retail online storage synced with what must be your main camera (i.e. your phone) does the trick, doesnât it?
Enforce MFA and use a password manager.
Use the least possible apps. (mine are messaging, streaming services for music/films, banking, end of story).
Disconnect and make social medias a thing of the past.
Get bored as hell and waste your time on some forum wondering what to do with your money and your life now that youâve wiped everything you donât really need.
20 years ago IaC and declarative blabla did not exist. And itâll soon disappear, be replaced, iterating to a more fancy pattern to solve the issues IaC has created.
If any of you has some magic trick to keep being motivated by soon-to-be-obsolete stuff, a.k.a. IT, let me know.
Nice effort by op by the way, congrats (and thatâs serious). letâs talk in some years, counting maintenance effort to keep it up to date and efficient compared to whatâs on the market.
Photos and videos of my life, collected since 2007. DSLR photos, iPhone photos and videos, GoPro videos, DJI drone photos and videos. The value of it is immeasurable. Plus roughly 12TB of movies and TV shows. Carefully collected and organized.
If you actually have things that should stay encrypted forever, putting it onto the cloud is not a good option.
Opinions might diverge, but I donât think current encryption methods will hold until 30y in the future.
Whether you still care if someone cracks it in 30y is another question though.
But this part (what movies, how organized,âŠ) you can store in 1 text file and if you lose it you download it again and organize it the way you specified in the text file, no? Unless this is material that canât be retrieved anymore.
Is there a legal way to own these?
And your home-made NAS and its tech will last 30 yrs for sureâŠ
Yes, download them.
@almi Itâs still a lot of work. I use tools like MKVtoolnix to remove unnecessary audio and subtitles (only leave German and English in), this takes manual labour and a lot of computing time. Plus certain movies might not be available anymore after some time because they are too ânicheâ.
@JEPG Well downloading movies and TV shows is legal in Switzerland.
Well, itâs legal to download and watch copyrighted content for personal use.
Sharing and distributing copyrighted content without authorization is illegal. Imho thatâs your torrent & co.
So I wonder how you download it from a legal place since Iâve never heard of legal distribution of drm-free offline copies of copyrighted content, but Iâm surely outdated.
Itâs legal to share it with friends and family for free. SR 231.1 - Federal Act of 9 October 1992 on Copyright and Related Rights (Copyright Act, CopA) | Fedlex
Itâs not regulated where you got the movie from but only the distribution of thereof. I mean back in the days one person just bought the âlegalâ DVD/CD and distributed it to others so they could burn their own copy.
The whole streaming thing is actually relevant to FIRE. I save a ton of money by not paying for Netflix, HBO etc.
I also hate it when they suddenly remove a movie or TV show that used to be listed.
Time to make lot of friends whose name ends with .torrent.
I still find it sketchy ethically. Especially because I make a living of people paying for copyrighted content.
Even if I would use torrents: as Adguard Home is handling my DNS servers, my ISP doesnât see what Iâm actually doing on the internet. They only see when Iâm online and how much traffic Iâm generating.
I used to collect Bluray movies. But this is much more convenient 
Using a separate DNS doesnât really hide the traffic (ip/port and other metadata are still visible, and even with encryption like TLS the shape of data can give away the type of flow). ISP (and intermediaries) will still be able to know itâs torrent flows.
Living cheap is one thing, not paying for other peopleâs work you enjoy is something else. Well itâs cheap too, in a wayâŠ
No one has claimed that the initial harddrives/NAS survive for 30+y. But the point of the whole RAID redundancy and backup effort is that the data does survive this timespan.
Now for the 12TB movie part, it probably wouldnât matter if someone decrypts it at some point. Hence an offsite backup with a cloud provider would be a viable option.
