    This is from a FreeBSD system, but I believe the similar commands exist in
    AIX 5. I wrote this to backup a FreeBSD system. It runs every other day
    via cron at 1:00 AM.

    Instead of "burncd", use "cdrecord". "mkisofs" is in AIX.

    Creating a backup to a DVD-CDW is done by doing a, /usr/sbin/mkcd -d
    '/dev/cd0' -V 'rootvg'.

    Is it possible to write just a few files to a DVD-CDW more than once, say a
    few files a day for a month?

    Can you provide me the command syntax?

    TIA.
