Is your cdrom/dvdrom read/write? If yes, try mounting the cd normally then try.. Never tried that before
eg
mount -F hsfs -o rw /dev/rdsk/c0t6d0s0 /mnt
ufsdump 0f /data /mnt/

Incredible, your solution won't work as hsfs is a read-only filesystem.

Outside perhaps DVD-RAM, I doubt you can write to any cd/dvd media directly using its raw device as output file.

man cdrw


if you don't have cdrw then install SUNWcdrw

I cant remember the commands off the top of my head (For Solaris) but just going on pure logic I think you have to use the two steps below.

1 ) create an iso image of the directory you want to backup (I think you can use the "mkisofs" command)
2 ) then burn the image to the cdrw device using the "cdrecord" command

I know the above works on linux with the following commands, you may have to change parts like the device file name to work with solaris

1) mkisofs -r -o cdimage.iso /mybackup_dir
2) cdrecord dev=/dev/cdrw speed=44 driveropts=burnproff -eject -v cdimage.iso


.. hope this helps

The iso must fit on the media so this procedure isn't as easy as with a tape device.

The cdrecord command can be replaced by the simpler:
Code:
cdrw -i cdimage.iso
