    Hi admins

    i received lot of answers to my question. Most of them say to use "-f
    serveur:device" option of fbackup. But this method is very slow.

    The best one i received and used (through a gigabit LAN, it works fine) is
    the following:

    I would suggest using fbackup with dd. "standalone" fbackup on the network
    is rather slow.
    And you can use it with remsh or ssh in this way.

    The key: use the same block size with dd at the restoration as with the
    fbackup.

    To restore you can adapt the following examples:
    (My original example mail for one of my customer is a long hungarian mail.
    I'm lazy to translate it; please see fbackup and frecover man pages)

    1.to check/read only the content of the tape:
    remsh gaia dd if=/dev/rmt/0m bs=128k | frecover -r -N -v -f -

    2. To restore /tmp/1 to /tmp/test (local usage, you can add remsh/ssh to use
    it via the network) cd /tmp/test dd if=/dev/rmt/0m bs=128k | frecover -x -v
    -X -i /tmp/1 -f -

    3. To restore a single file to the current directory (the same applies):

    dd if=/dev/rmt/0m bs=128k | frecover -x -v -X -F -i
    /tmp/1/depot/catalog/INDEX -f -

    Thanks to all.
