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?
I appreciate your goal, but this sounds like a privacy nightmare and extremely dangerous legal minefield. Most data worth backing up is important to keep private. If whatever encryption you’re using is discovered to be vulnerable to realistic decryption by a third party, then you’ll have the seeds (no pun intended) planted for your data theft even before knowledge of the vulnerability exists.
The legal angle is even more worrisome. Imagine if the person you gave backup space to on your network decided to store legally objectionable material in your house on your machines. You would be subject the penalties. Big companies get around this legal landmine by having Service Agreements and attestation that you won’t be storing that kind of data.
The cheapest method for off-site secure personal backups would be to get a bank safe deposit box and an external hard drive.
