See [blog post](https://blog.liw.fi/posts/2020/10/16/obnam2_-_a_new_backup_system/). It is currently not ready to be used, but if you're feeling adventurous, follow [the tutorial][tutorial] and try it out. This web site used to be about Obnam1, the original version that was retired in 2017. All that content has been dropped now. **25-word summary of the new architecture:** client splits live data into chunks, then compresses and encrypts them, and uploads new ones to smart server via HTTP; server never sees cleartext.
