• Backs up and restores Windows EFS files.
• Storage and network compression using zlib.
• Ability to continue interrupted backups.
• Client/server communications encryption with SSL.
• Automatic SSL certificate authority and client certificate signing.
• Client side file encryption - (note: this turns off delta differencing).
• Scheduling.
• Email backup success/failure notifications.
• A single daily backup summary email.
• A live ncurses monitor on the server.
• Fifo read/write support.
• Pre/post backup/restore client scripts.
