Subject: Re: Differential incremental backups

Robert,

I used incrementally updated backups in 10gR2 (or at least thought that's what I was doing). A quick peek at the docs confirmed that they did exist then:

http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/bkup004.htm#BRBSC186

Is there something distinctly new about them in 11g? Or are we not talking about the same thing?

Cheers,
Don.
