Obnam is starting over from scratch. See blog post. It is currently not ready to be used, but do check in later. See roadmap for current plans.

This web site used to be about Obnam1, the original version that was retired in 2017. All that content has been dropped now.

Obnam2 acceptance criteria are documented using Subplot, and are on docs.obnam.org.

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.
