I guess I lied - I'm not using cdrecord, but rather growisofs.

Nevertheless - here is an example of how I am using it.


    # this script takes stdout from zfs send and shoves it through a
    pipe into
    # splitpipe. Splitipe will chunk it into DVD size chunks.
    # $1 is the zfsfs at snapshot

    zfs send $1 | splitpipe -n -s dvd -o 'growisofs -speed=16 -Z

As you can see - I could zfs send to tape, floppy, cd or some other medium.
