Re: Low deduplication for Oracle DB backup

check filesperset setting. this should be to 1 for optimal de-duplication - anything other than 1 backups will be multiplexed which means data will be received in different order every time.  compression could still be enabled and used by default even if not called to do so by the rman script. change rate could also be a factor to low de-dup.
