there is dar, disk archive, which can make slices and span disks/cds/dvd/floppies and write indexes to disk.
Dar (Disk Archive) is a hardware-independent backup solution. Dar uses catalogs (unlike tar),which it makes it possible to extract a single file without having to read the entire archive. It is also possible to create incremental backups. Dar archives can also be created or used with the libdar library (for example, with KDar, a KDE application). This package contains the command line tools and documentation.

there is also a gui available but not build for openSUSE, dargui. but it must be easy to build as I have it installed/working.
<https://en.wikipedia.org/wiki/Dar_(disk_archiver)> No mention of DVD there. http://dar.linux.free.fr/doc/presentation.html Ah. there: «From a filesystem, dar creates an archive, which may be split in a set of files (called slices) which size is user defined. Dar archives are suitable to be stored on floppy, CD, DVD, usb key, hard disks, and since release 2.4.0 to tapes too. But no, dar itself cannot burn a DVD. Instead the user can give dar a command to execute each time a slice is completed. Dar can perform full backup1, incremental backup2, differential backup3 and decremental backup4. It also records files that have been removed since the last backup was made, leading the restoration of a system to get the exact same state it was at the time of the differential/incremental/decremental backup (removing files that ought to be removed, adding files that ought to be added and modifing files as expected).» I don't have clear if the archive has to be created first on hard disk. I think this is the case. Maybe "Lazy Backup". <http://lazybackup.sourceforge.net/> Ha! Look, missing feature: "parchive - to recover from lost or damaged disks " The PCtools backup did that on 1980. No one I know does it now. Look at this one, interesting: <<new in 2017>> Darbrrd by Jared Jennings, to back up a few hundred gigabytes of data onto dozens of optical discs in a way that it can be restored ten years later. <https://github.com/jaredjennings/darbrrb> dar-based Blu-Ray redundant backup - -- Cheers, Carlos E.
