Netbackup Appliance deduplication/re-hydration problem

Hi

OK. In that make sure you're not running backup to the pool while you're duplicating frmo the pool to tape. Also make sure you run very few stream simultaneously for the duplication. I'd keep it between 4-8 depending on your amount of tape drives.

I've previously performed tests and found that running more stream just increases the load in terms of processing (rehydration) and your overall performance declines rapidly.
