-the Obnam project is retired}.  You should use another backup solution instead.
-
-Obnam was an easy, secure backup program.  Features included snapshot backups,
-data de-duplication and encrypted backups using GnuPG.  Backups can be stored on
-local hard disks, or online via the SSH SFTP protocol.  The backup server, if
-used, does not require any special software, on top of SSH.")
