    Just simply; wow. I read the above maybe 30 minutes ago, did a search,
    downloaded, compiled, installed, then

    tar -cvf - /home | cdbackup -d /dev/scd0 -r 0,0 -l 700 -a "/home backup"

    and voilą, I apparently made my first backup on CD with Linux ever...
    Just plainly terrific and simple.

      - I backup every night, on a circular list of seven media (monday,
    tuesday backup and so) the week after, each media is overwritten.

      - From time to time, when going at the bank, one media is put in a safe.

      - We have small files (texts, spreadsheets, quicken data from 12 years
    ago, some programs and archives from my work) Not too much, but quite
    important.

    Question: We can use a list of seven CD on which we can write over and
    over and over?

    How do you "tar tvf" the data written on CD? "cdrestore" just show me

    [root@heron bin]# cdrestore -d /dev/scd0 -q
    Tracks: 1
    Disk size: 666000 kB ( 333000 blocks)
    Space used: 191220 kB ( 95610 blocks)
    Space avail: 451980 kB ( 225990 blocks)

    Track 01: 186 MB: 12/26/2003 09:01 Part 1: /home backup
    [root@heron bin]#

    Will do more tests as for now.

    Thanks for all of you people
    Gaetan
