+supports compression and authenticated encryption.  The main goal of Borg is to
+provide an efficient and secure way to backup data.  The data deduplication
+technique used makes Borg suitable for daily backups since only changes are
+stored.  The authenticated encryption technique makes it suitable for backups
+to not fully trusted targets.")
