Is there a difference de-duplication ratio between normal Oracle and exadata oracle?
Hello.
We have verified that the customer's exadata DB has a lower deduplication rate than our estimate.
Is exadata typically less deduplicated than regular Oracle? Or is it a special situation?
Typically, I average the deduplication rate of oracle (avamar, data domain) as 50 % ratio first initial backup and 90 % ratio Daily full backup.
thanks.

Make sure your mtree is tagged as Oracle1
Make sure things like Oracle encrypted storage is turned off and RMAN compression is off too.
