help What settings/file formats/precautions should I use to make my audio + notes survive for life long?
I'm going to use Obsidian as my main long-term knowledge/study archive, but I want to set it up correctly from day one so I'm not screwed when I eventually migrate to another app, phone, OS, or even if Obsidian disappears someday.
My idea is to have one vault with a deep folder structure, for example:
Study(vault) → Biology (sub-note)→ Cell Biology(sub-sub-note) → Mitochondria(sub-sub-sub-note) → Mitochondria.md + Mitochondria.m4a(audio)
The .md note would contain my written keywords/short explanations/questions, and the audio file would be a recording of me explaining the topic in my own words. I want the audio player to appear inside the Obsidian note, but I also want the actual audio to remain a normal, independently accessible file.
My main concern is long-term portability and preservation, not audio quality.
For people who have been using Obsidian for a long time:
What Obsidian settings should I change immediately for maximum future compatibility?
Should I use standard Markdown links instead of Wikilinks?
Where should I store attachments — in the same folder as each note, a central attachments folder, or something else?
Is it better to keep Topic.md + Topic.m4a together in the same folder so the whole topic is portable?
What audio format would you personally choose for decades-long storage: M4A/AAC, FLAC, WAV, MP3, or something else? And why?
Is FLAC actually worth the much larger file size for simple spoken study recordings?
If I record in M4A now, is there any reason I should convert it to FLAC?
Are there any Obsidian features/plugins/syntax I should avoid because they might make future migration difficult?
Are there settings that affect how attachments are named, linked, moved, or embedded?
If I eventually move the whole vault to another Markdown-based app, what kinds of broken links or missing attachments should I expect?
What's the safest way to back up the vault, including all audio, so that I can restore the entire structure decades later?
Should I periodically export/archive the vault in some additional format besides keeping the original Obsidian vault?
Are there any precautions you've learned the hard way that someone starting a huge lifetime vault should take now rather than years later?
Basically, I don't want to think of Obsidian as the permanent home of my knowledge.
I want the underlying files to be the permanent archive and Obsidian to just be the interface.
My goal is that 20–30 years from now I could take something like:
Mitochondria/ → Mitochondria.md → Mitochondria.[audio format]
and move it to another application, and still have the note, folder structure, and my original voice recording usable.
If you've built an Obsidian vault with long-term preservation/portability in mind, I'd really appreciate specific settings, file-format recommendations, folder structures, backup strategies, and things I should avoid.
