Record on CD-R(W) a) FreeBSD's burncd % burncd -e -v -s 16 -f /dev/acd0 data cdr.iso fixate b) The port cdrtools (includes cdrecord) % cdrecord dev=1,0,0 speed=16 -v -eject -tao -data cdr.iso 2. Record on DVD+-*/R(W) The port dvd+rw-tools (includes growisofs) growisofs -dvd-compat -Z /dev/dvd=cdr.iso This example implies the following setting in /etc/devfs.conf: link cd0 dvd Alter device to fit your needs. As aleays, check the manpages. They're helpful and include kind-of copy & paste examples. Note that 1 b) and 2 need atapicam (in kernel or via kldload). For 1 b), you can check which SCSI ID corresponds to your recorder using the command % camcontrol devlist Have in mind that permissions have to be set correctly in order to access these devices for writing. It's intended to be that way. :-) Finally, check the optimal writing speed for your CDs and DVDs. > So long as this is readable on FBSD, Linux, or a Mac, I'll be > happy. These platforms will read everything that has been mentioned in this thread already, because they're real operating systems (and not excuses for being none). :-) I think the ISO-9660 + RockRidge is the most comfortable way for what you intend - allthough the tar method (or even the UFS method) won't be any problem here. But as I said, maximum compatibility is always welcome for backups. -- Polytropon >From Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
