Oracle RMAN and data deduplication – part 2

Posted on February 11, 2011 by Ray

I have blogged about the poor deduplication ratios seen when using Oracle 10G RMAN compression before (see my prior post) but not everyone uses compressed backupsets.  As such, the question naturally arises as how well RMAN non-compressed backupsets deduplicate.

Posted on October 20, 2010 by Ray

I was talking with one large enterprise customer today and he was lamenting how poorly Oracle RMAN compressed backupsets dedupe. Apparently, non-compressed RMAN backup sets generate anywhere from 20 to 40:1 deduplication ratios but when they use RMAN backupset compression, … Continue reading →
