Obnam is starting over from scratch. See blog post. It is currently not ready to be used.

This web site used to be about Obnam1, the original version that was retired in 2017. Then it was about Obnam2, retired in 2024. 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.
