I wise man once said to me: "You cannot possibly call yourself a DBA unless you can properly backup and restore a database."

I'd add to that that if you can't do that, then database administration, no matter how well you may code SQL, is beyond your grasp and that you are endangering the welfare of your company's data and your company's livelyhood if they rely on it by attempting to fill a role for which you aren't qualified.

If not RMAN, then why isn't that DBA doing hot backups using shell or PERL???
Is there ever any discussion on what if disaster strikes?? Is there ever any discussion on what if boneheaded jr. sysadmin deletes a datafile? What if a disk gets corrupted or just dies? Is the answer simply to run like hell and update your resume?

Let me guess, your PHB who thinks nothing of overpaying for his car, house, food and mistress decided to be frugal with what he pays professionals who manage his business.
