Re: 11gR2 rman compression algorithms

No, I'm not sure. I copied that text verbatim from the book. The MOS note 563427.1 is probably the closest you're going to get to an explanation. But, I bet Fritz or Tanel could demonstrate conclusively exactly which compression algorithm is being used for each level using OS utilities.
