Purpose: setup an automatic encrypted off-site backup system that utilizes Amazon S3 with incremental backups by duplicity on the Mac (Leopard) or Ubuntu. Currently, I do have my own on-site backup system in place (nightly backups via rsync to external hard drive), but I am wary that some day my house may explode and I’ll have nothing left. Enter my new friend: the encrypted off-site backup.
Purpose: Install Netatalk (AFP) on Ubuntu with encrypted authentication (using OpenSSL), which is not enabled by default with the Ubuntu netatalk package. By default, the package installed from the Ubuntu universal repositories will transmit your password via clear text (you’ll know this because Mac OS X Tiger will throw a warning and Leopard won’t do anything useful at all).
