Hi,

I want to know what are the different ways available for backup and what are the advantages and disadvantages of each, better with an explanation or examples.

Any help is appreciated.

I have an application named Installgen which automates creating backup/recovery scripts along with creating the documentation for performing 15 different database recovery scenarios.

You may download a demo version of Installgen so that you may conveniently look at or modify the scripts on your own computer:

Or you may choose to browse the individual output files via the web:

Here is a full-featured RMAN backup script I like to use for situations where I am not using a recovery catalog:

RMAN is preferred by Oracle over the Hot Backup method because it generates less redo in the database and you can also throttle the amount of I/O used by RMAN. (I have implemented this functionality on my scripts.) This means that if necessary, you can perform the RMAN backup while users are actively using the server without consuming all of the I/O bandwidth of the server. You will need to adjust the default I/O rate to a value which is suitable for your server.
