Data Domain DD9300 expanded configuration, Data Domain OS 18.104.22.168-603959
VMware ESXi 6.5.0
Does anyone know how Deduplication and Compression work when they're enabled on both vSAN and DD? How can a deduplicated and Compressed block at the disk group level in vSAN be deduplicated in segments and Compressed again in the Data Domain system?
I haven't been able to find any documentation related to this info and the best practice around the capacity saving feature when both systems (vSAN and DD) provide them.
That makes sense. Thanks for your response.
By the way, VEEAM is our backup solution and we use DDBoost with our Data Domain.
