Per Metalink Note 247705.1 ... You can compress RMAN backup pieces at O/S level once they have been created but keep in mind that these are not directly readable by RMAN. You will have to manually uncompress these backup pieces before making them available to RMAN for restore. ... Does anyone do this or have any comments/thoughts? TIA.
