It would seem then that the O.P. who is already splitting his backup into 4.3GB chunks should split backups into sub-2GB chunks. 4,700,000,000 is the standard DVD size, I'd shoot for chunks of 4.5E9/3 so as to have about 200MB of headroom per DVD. growisofs will write 3 files to the DVD just as easily as one. The magic of growisofs is that it invokes mkisofs on the fly. And also that cdrecord had obnoxious (and broken) licensing in years past when I last tried it. -- David Kelly N4HHE, dkelly@HiWAAY.net ======================================================================== Whom computers would destroy, they must first drive mad.
