Some time ago, I implemented a little tool for myself which backups folders incrementally on usenet (deterministic message-id creation from a secret key, append-only style with metadata, parity, encryption etc. so you only have to remember one unique key to access all of your data, even if new data is added).

It can mount the current state of the usenet backup with FUSE and it's possible to browse through the files and listen to music etc. I understand that it might not be a good idea to store all your data only on usenet, but I thought that was an interesting concept and a fun little project to work on :)

Open source or didn't happen.

at the moment its very tailored to macOS and has plenty rough edges because its for personal use. But I'll gladly clean it up a bit and put it on github if enough people are interested and/or i will write-up how its "protocol" works. Just let me know (twitter pm or sth.) who is interested.

EDIT: basically it's one deterministic stream of messages for journaling everything, one recursive stream of folders and linked raw files. deterministic lookup rougly like: HMAC(type|index|revision|replication, key_for_locating) and it iterates through that

EDIT2: and one for parity of meta and raw
