        Even you would use amanda you don't save disk space :-)

        rdiff-backup technology saves disk space and net load but not
        cpu on servers  (python) :-)

        I didn't understand it. Each new 10MB file is a change. And it is
    authomaticaly stored in 'special directory' when do new backup.

        What is recreate a new 'special directory'?

        If you delete this spec dir, you can't  recreate  backup.
        This is dangerous to delete enything in stored tree since
        reverse increments upon on it :-(

        Because of that I have partition, the backups are stored in,
        read-only.

        :-)
