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. **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.
