Two weeks ago, we announced that there would be regular technical tutorials coming up to leverage the use cases of our open-source Scality S3 Server. We started with explaining how to set up SSL, a protocol that enhances security when communicating with Scality S3 Server. Today, we want to help you use Duplicity, an open-source tool, with Scality S3 Server, in order to save backup space in your storage. Duplicity allows you to backup a compressed version of your files (a tarball), which is the first way it saves you disk space. The second way appears when you want to.
