Oracle DB Backup Procedure

        Dear,
[Quoted]         I would be really very grateful if someone could give
        me good hints on how to backup an Oracle DB.
        I know there are many ways and tons of docs, but what I am
interested in are
        the general principles to perform a good Oracle DB backup, tricks
and/or crucial
        points.

        Please e-mail me at palafra_at_tin.it

        Many thanks in advance for your very appreciated help.

        Kind Regards,
        f
