Is a FOSS decentralized peer-supported backup service feasible? (lemmy.wtf)

While Apple has iCloud and M$ has OneDrive, both offering 5 free GB of storage, most Free backup services written for Linux are focusing on saving your data to your own hard drive lying next to your computer. That is troublesome and not the most reliable as in case of a house fire or a flood it will burn or drown along with the machine. Some offer an option to buy some storage from a third-party provider like Amazon, but that's again non-open and troublesome.

Is a free&Free peer-supported service possible? Where, similar to torrent tech and PeerTube, you allocate some storage on your PC to someone's backups, and can publish your data on the network in return, so that data would be distributed between computers and could be requested on demand?

Yup, or if someone breaks into your house and steals your computer.

My backup plan:

primary - a ZFS server at my house
secondary - an offsite ZFS server at a relative's house
primary takes ZFS snapshots periodically and sends encrypted snapshots to secondary
both are connected via netbird

The primary server is actually a bigger more powerful desktop, while the secondary is just a small, power-efficient, weak NAS that's just for storage. Small is good so you can hide it and it doesn't annoy your family member.
