I'm trying to setup backups to the DVD-RW drive on our new server before it goes into production. I've got the DVD-RW drive working, and I figured out how to dump to it: # dvd+rw-format /dev/cd0 # dump -0 -uL -C16 -B4589840 -P 'growisofs -speed=4 -Z /dev/cd0=/dev/fd/0' /usr A test restore comes out clean: # restore -Nxvb /dev/cd0 The problem is most of the partitions are tiny (< 1G) and I would like to fit more then one partition on each DVD. I figured just passing -M (append data) instead of -Z (new session) would do it: # dump -0 -uL -C16 -a -P 'growisofs -speed=4 -M /dev/cd0=/dev/fd/0' /home But growisofs fails with :-( /dev/cd0 doesn't look like isofs..., and of course dump fails with "Broken pipe". Any clues to how to get this to work? (Webpage link is sufficient if there is something out there. I couldn't find one.) I'm fairly new to the FreeBSD/UNIX world, so please be gentle. Thanks, -james
