You may want to review this MOS note ACFS Technical Overview and Deployment Guide [ID 948187.1] I'm not sure if they've updated the whitepaper, but last time I checked here are my notes *?> ACFS now supports RMAN, DataPump<file:///C:/Dropbox/Documents/KnowledgeFiles/InformationTechnology/TiddlyWiki/karlarao.html>on 11.2.0.3 above... BTW, it does not support archivelogs? You still have to have the FRA diskgroup to put your archivelogs/redo. At least you can have the ACFS as container of backupsets and data pump files* -- Karl Arao karlarao.wordpress.com karlarao.tiddlyspot.com -- //www.freelists.org/webpage/oracle-l
