So, my question is : how to write large files on DVD (files > 2 GB).
I couldn't care less about k3b, take it up with their bugzilla if you want, but first find out what mkisofs can do because k3b won't do more than that. You can't portably put files >2GB on an iso9660 filesystem, though newest mkisofs may be able to do it. If you just do backups for yourself, portability isn't necessarily an issue. Try using udf instead of iso9660, i.e. use -udf with mkisofs. Do some performance tests on reading the files. It will store files >2GB, but it also loses a lot of the file meta data (permissions, ownerships, ) and storing anything but plain files may be risky. Beyond that, it's a pain. You could stream the output of tar straight onto DVD, i.e. not use a filesystem at all. Random access for reading isn't all that good, but it does store all the data. Oh, multivolume and tar could turn into a pain. Whatever you do, as always, test the backup can be properly restored...
Thanks for the answer Volker !
I understand pretty well that k3b can't do more than mkisofs or growisofs, as it is just a front end. That was just the starting point of my (unfortunate) tryings ....
Well, a fiend did a burning on a gentoo system just beside me, and I'm pretty jealous of it ! (of the burning, not of the gentoo system ;o) ).
All the files (>2GB and <2GB) appears well on the dvd, and M$ windows says the filesystem is CDFS ...
So I just wanted to know what he could have done to make it work (as he doesn't know himself ...) knowing that we have same version of k3b, mkisofs and growisofs ...
I'm going to try immediately mkisofs -udf, and I hope I'll do something with it ...
