-              Karbor deals with protecting the Data and Meta-Data that
-              comprises an OpenStack-deployed application against loss/damage
-              (e.g. backup, replication) - not to be confused with Application
-              Security or DLP. It does that by providing a standard framework
-              of APIs and services that enables vendors to introduce various
-              data protection services into a coherent and unified flow for
-              the user.
