RE:Hot backup and TEMP tablespace

ALWAYS BACKUP THE ROLLBACK TABLESPACE!!!!! or you will not be able to recover. How else will Oracle rollback a transaction in the works when the database went down.

I do not back up TEMP or my INDEX tables spaces. I have scripts that recreate all of these. (150GB of indices, not worth the tape.) And while I use RMAN for backups I do all my recoveries from the our scripted hot backups. I also practise recoveries every 6 months.

RMAN backups fine, it's recoveries it has trouble with :) Why?

There is limited flexibility with RMAN along with an added dependency. As most know I loathe unecessary dependencies.

An Example:

        power surge blows out Machine and hub/router power supply.

        Machine automagicaly fails over to alternate power, however, the hub/router needs servicing. Your RMAN catalog is on the other side of the hub/router. What are you going to do now?

And yes, as I keep saying, I am paranoid.
