Hot Backups - Oracle 9i, 10g and 11g
Are all hot backups run outside of RMAN as an OS file copy? If so, isn't this a very risky exercise.
I understand that RMAN will check for corruption where as hot backups won't. RMAN can also track backups in a recovery catalog.
If using a hot backup, it seems like corrupt data could be backed up with the good data.
What exactly are the advantages of using a hot backup. It is understood that the databases can be up during a hot backup, but can't they also be up with an incremental RMAN backup?
