dkopp binary package in Ubuntu Focal ppc64el

 Dkopp is a program used to copy or back-up disk files to DVD or
 BD (Blue-ray) media. Full or incremental backups can be done,
 with full or incremental media verification. A GUI is used to
 navigate through directories to select or de-select files or
 directories at any level. Backup jobs can be saved for later re-use.
 New, deleted, and updated disk files are handled automatically,
 without re-editing the backup job. An incremental backup updates
 the same DVD/BD media used for a prior full backup. Files can be
 restored to the same or another location on disk. Large backup
 jobs can be done using multiple DVD media.
