Offers efficient data management with robust features and reliable performance
Dell PowerProtect DD (Data Domain) can be improved in terms of price. While Dell is providing a proper device, other solutions, such as Symantec, can replicate their data through any NAS storage. Although their deduplication and compression might not be as effective, they can still accomplish the task. Medium-level and SME-level businesses can easily utilize this feature, but Dell PowerProtect DD (Data Domain) is a relatively expensive solution to propose to customers.
