Hello,

Please help me with the following question:

Our primary copy will be stored in a backup appliance. Hardware deduplication will be used so we will disable Commvault’s deduplication for that copy.

Our secondary copy will go to a object storage (on-premises). That storage can also deduplicate but the achievable reduction ratio is nowhere near what Commvault’s dedup can provide. So we would need to enable Commvault’s dedup for that copy.

Isn’t it contradictory that CV’s dedup is disabled for primary but still needs to be enabled for secondary? what would be the right strategy for deduplication when having a backup appliance and a object storage in our backup environment? Would it be better just to use CV’s dedup and not take advantage of HW dedup?

Thanks for the help!
