You have to be an OCP before you actually care about the customer. ;-)

Seriously, I understand Alan's sentiment, and frustration. I've had more than 
one client that insisted that they didn't need backups. The *good* DBA will be 
able to communicate the volumes of reasons why. 

There are a few times that a no backup strategy can be justified in my opinion 
(such as a case where a duplication of Dev from Test or Production is truly 
acceptable and workable), but even there a backup is often a faster restore 
method than a duplication. 

At the end of the day though, if you accept the charge for the DB with or 
without backup, you also accept the responsiblity to do your best to support 
the customer in as much as they are willing to pay for the hours it will 
require. At the end of the day if you are billing 80 hours to restore a 
database and the customer is surprised... then you didn't do your job as the 
DBA at the begining of the day (or during the day). Of course, if you come on 
the scene in an emergency capacity then all bets are off.

Can you be an Oracle Certified Associate and let the CT BURN? Glad I'm
not certified!
