our Oracle database has grown very large as of late ~= 400 - 500 GB and saving to filesystem is not scalable anymore to us. We are looking at using RMAN to backup to tape (directly, not to fs then tape).
Anyone can shed a light on this please?
OS is Enterprise Linux (Redhat/Centos), and 11g oracle.
EDIT: I'm looking at a way of using RMAN in tandem with linux commands to achieve this, as the power-that-be wants a simple solution.
