    just to get you started with another back up h.d
    #!/bin/sh

    export
    PATH=/usr/local/bin:/usr/bin:/bin

    LIST="rootfs usr data data2"

    for d in $LIST; do
    mount /backup/$d
    rsync -ax --exclude fstab
    --delete /$d/ /backup/$d/
    umount /backup/$d
    done

    DAY=`date "+%A"`

    rsync -a --delete
    /usr/local/apache /data2/backups/$DAY
    rsync -a --delete /data/solid
    /data2/backups/$DAY

    Yes it is a simple idea.
    You indicated rsync, I guess you did not read the section 4. History

    No, I was trying to show you why rsync was not a good solution.

    what ever.. Ive only used it on a couple of e-smith servers... its
    working well and having the full drive mirror is ok in this case.. so
    apart from an expensive tape unit .. what do you suggest ?. personally I
    favor Beowulf clusters... (but not always viable)
