Larry,

     I have worked on accounts that use RMAN to create backups to files.
We then typically use TSM ba client to do archives or backups of the files
which can allow you to provide retentions and offsite copies.  I preffer
archives so the data is retained for a set length of time.  If there is
enough space on your sata drives that are assigned to the database server
then you can literally just let rman create as many backups as you have
space.  RMAN is an oracle tool and the TDP for Oracle allows the RMAN to
tie into TSM.



We were setting up the TDP for Oracle for the DBA's.
We are also adding a SAN.
The DBA's have said that with disk based backups (which
we are moving to with the SATA drives), they can use
RMAN without TSM.
I do not know enough about RMAN to know if that is true.

Any one out there that has a SAN and Oracle and just
backs up to disk without TSM.

Preiviously we used SQL-BACKTRACK and TSM for Oracle.
