Re: Low deduplication for Oracle DB backup
No worries about your English. It is much better than many people born in the U.S. 🙂
Yes, I have taken that into consideration, that deduplication would be lower if only incremental backups happen daily. Thats mainly unique data, which cannot deduplicate, That would explain why my daily incrementals would be 1 to 1.5. 1x compression is no compression at all. But, it seems that my full backups should be much higher than 7x average deduplication. Granted, I do not know what percentage of those full backups are new data. If its a high percentage, the dedupe would be low.
