Hei,

What are the fundamental differences between a SNAPSHOT CONTROL FILE & CONFIGURE CONTROLFILE BACKUP …:

· Can both be used for a restore? So if a snapshot is set up and running, we don’t need to take an explicit Control File Rman backup or to set CONFIGURE CONTROL FILE BACKUP…?

· If each time we run an RMAN backup, RMAN automatically take a backup of the Control File (CONFIGURE CONTROL FILE BACKUP…), why do RMAN need to take a snapshot of the Control File? Isn’t it duplicating the job or it has a totally different purpose?

Thank you for your help!

Best regards,

Patrick.

It is a duplicate way to backup your control file.
But in matter of backup duplicate is a good thing.
Snapshot is easier to use but can be accidently dropped.
