Imagine that things gone bad and all we have is a fresh Windows Server and full cold backup of our Oracle database.
In case of SQL Server 2000/2005/2008/2012 it was really a matter of few mouse clicks: copy backup files, install db instance, restore files with few clicks, recreate users and we are good to go.
But now we are setting up Oracle 11g DB Standard as our database solution and from what I've seen over Internet it's a really complicated issue up to the point where this cold backup files might become completely useless without "actions" taken outside "usual" backup procedure.
While looking for answers, I've ran across certain topics like "db duplication form backup without access to flash recovery area" and etc which looks like to be close to what we were doing in SQL Server. Problem is all this things are far outside of my own experience (SQL Server, remember?) so I can't even tell if I'm looking in a right direction.
So my question is (I'll split it in two, because I think it matters in Oracle):
1) What should I do in order to properly "backup" my production database and restore it lately on different machine in case of emergency if we have not got yet any emergency instance installed?
2) What should I do in order to clone my production database and restore it on prepared instance (to clone production db).
What's most important: is there a common approach to both this tasks like in SQL Server?
