Does anyone use 9i RMAN for VLDB's? I need to keep the a full backupset compressed on disk: by directing files for RO tablespaces to one directory, and rotating RW tablespaces in another directory to try and keep a consistent backup on disk at all times. 9i Incrementals are no good as it will scan hundreds of GB of RO tablespaces daily searching for changed blocks. Does anyone see a problem with this sort of RO/RW split? Or does anyone know if SQL*Backtrack does anything clever for large(ly) RO VLDBs?

Thanks!
Mark
