For personal use, no. There is no benefit.
For something like a home cluster, yes I would use something like Ceph to spread the data over several systems.

All things and everything about decentralization: news, announcements, proposals, and discussions about decentralized apps, protocols and communities.
- decentralized web (dweb)
- peer-to-peer (P2P)
- file-sharing (e.g., BitTorrent, IPFS, and Gnutella)
- self-hosting
- federation (e.g., ActivityPub/Fediverse and Bluesky)
- federated apps (e.g., Mastodon, Lemmy, and Pixelfed)
- cryptocurrencies (e.g., Bitcoin and Ethereum)
Rules
- Be polite and follow the rules of our instance lemmy.world.

What about backups? I mean for someone who hasn't (a paid) one already.
I ran a couple decentralized filesystems 20+ years ago on FreeBSD. It was cool but I didn't find it was worth the headaches for my use cases as compared to spinning up a raid array and nfs exporting it.
Ah I see. So you had a local decentralised file system, am I understanding that correctly?
Sorry, I misinterpreted "decentralized" as "distributed"
No problem, they overlap quite the bit.
Yes, just on LAN. I'm having trouble recalling names. I think it was a project out of Cornell? No... CMU! It was "Coda"!
I mean, I don’t really have a use case for a remote file system my self currently, decentralized or otherwise. It’s an interesting idea though. I’m curious how that would even work.
I could imagine it being useful for some organization that has membership that fluctuates consistently. Precluding relying on anyone to manage or host a central file server. Or an organization that can’t rely on a central server staying up due to some adversarial relationship with another party.
Or something on a mesh network that pulls the movie you want into RAM from the nearest network node that has it.
It's not like it's sloppier than how android works.
If you want more info just ask away, but in a nutshell my system is based on reciprocal sharing (I share yours because you share mine), so as soon as there are a bunch of users, there will never be a shortage of storage space. Most other systems are based on benevolent users who donate space, but I feel it might not scale well.
Is it a matter of everyone having a copy of every file? Or is there some sort of limit, like, a certain amount of people connected having a copy being deemed enough to ensure that it will always be available?
You decide, so if you want a redundance of 10 for example, you'd share ten (similar sized) files and ten others will share your file.
I’ve used ceph (very little) and longhorn for Kubernetes storage. I’ve never really looked into distributed filesystems but could see something with a longhorn or lower level of administrative complexity as something I would use. The replication and fault tolerance would be my primary interest. Some sort of network share on top of the distributed filesystem too, like windows DFS sort of?
Also, again, never looked into distributed filesystems much but if there was a mode where a distributed filesystem could replace syncthing for ensuring a copy of the data was replicated to specific/all machines, that would be interesting. Specifically I’d like to replicate my media share to my laptop so I have it when offline / traveling. I’m all on Linux these days but something like what windows has where you can make a network share available offline and it just caches it to a local directory…. Feels like a distributed FS could do something similar.
I do. It's in beta. It's called veilid. Check out veilid.org
Any info about how it works/what it is more in detail? The website only lists a couple of people and a donation page.
Yeah sorry about that I didn't do a good job there..
Hmm, so at a first glance it's IPFS with obfuscated routes plus there seems to be other possibilities, but for now it wants to be more of a framework for future applications?
Interesting, do you have any real world usage examples, like what do/can you use it for, and how do you use it?
Cheers
I'm so glad you asked!
Look up veilid chat in the Google play store...
And join the discord!
And if you like, I think the command to install a node is sudo apt update sudo apt install veilid-server veilid-cli
Very interesting!
Can't find a Veilid chat though, Veil chat maybe?
Discord, talking instead of writing 😅?! I'll try 😊

This may not work... Not sure how beta programs work in Google play.
I applied for the beta ages ago, maybe it hasn't opened up again yet. Maybe it's full.
Depending on how we are defining it, I have used several in my personal and professional lives. I dont see a compelling use case for me currently in my self-hosting setup.
you might find peergos interesting
I do!
Peergos is an open-source project
So it's Dropbox with FOSS and encryption if I understands it correctly, very neat!
The only drawback is it's centralised, but I will for sure check this out.
