Hi, > -use-the-force-luke does work exactly as you thought and explained.
One should mention that in the growisofs man page. I would propose the paragraph with "-Z option non-interactively". > All I need to do now is sort handling files greater than 1GB. 2 GB minus 2 kB is said to be the maximum safe size of a file within a ISO file system. Everything up to 4 GB (minus ? kB) seems to be possible but is of questionable readability. Check with every single intended reader system. I understand that with mkisofs 4 GB is the absolute limit for a single input file. Since you work with a single tar file, consider to write the file raw to DVD growisofs -use-the-force-luke -Z /dev/cdrom=mytarfile.tar resp. on the fly : tar cf - ...your.tarfile.content... | \ growisofs -use-the-force-luke -Z /dev/cdrom=/proc/self/fd/0 That would not be mountable but readable by tar tf /dev/cdrom About readbility with MS-Windows i quote Andy : "tar ztf '\\.\d:' and there're other ways... a." As an alternative consider backup projects like http://www.serice.net/shunt/ which produces automatically chopped tar files wrapped in ISO9660. My own project creates either ISO9660 trees where after mount the files are accessible directly or afio archives which are written raw to DVD. http://scdbackup.webframe.org/main_eng.html For dealing with single files >= 2GB it needs a disk buffer of up to 4.7 GB, though. You will get them backed up in pieces and during restore will have to put them together by hand. > Aren't DVDs fun !! Yes, they are. But don't forget to checkread them. I have experienced DVD-RW which silently returned false content. No i/o error but simply a non-matching MD5 checksum when checkreading them. I had a DVD+RW which alernatingly returned correct and non-correct checksums. After the next re-write it was ok.
