Ohhhh, here we go again.

I don't care what logic, documentation, oracle support and/or common sense have
to say on the matter.

Back up those redo logs!

Just don't restore them unless you need them.

'shutdown immediate' doesn't always work the way one would hope, especially
on Windoze NT. I've restored a database here which required those online redo logs for recovery.

Think of it as cheap insurance, and one less reason to keep your resume up to date.

                 For cold backup, oracle does not recommend backup the 

online redo log. And if you restore the whole cold backup, why need the online redo log? I am sure people doing cold backup will do shutdown normal/immediate, not shutdown abort.So there is no need to backup the online redo log at all! Backup the online redo log also take the risk of damage the current online redo log when you want to do full recovery.

                 So, never backup the online redo log when doing cold 

backup.
