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.

A scalable solution with Veeam and Vertias alliance
I am impressed with the tool's technical alliance with Veeam and Veritas.  The product needs to improve performance while scaling out. It also needs to improve stability.  I have been using the product since seven years.  I would rate the product's stability a nine out of ten. I would rate the…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The solution is very scalable."
"The solution is very stable."
"It's deduplication and faster recovery that are the key features."
"The hardware can operate in high temperatures, in case of any disaster."
"The compatibility within the Dell PowerProtect DD portfolio makes data management more seamless. This integrated solution improves efficiency in our data center and simplifies operations by relying on a single company for servers and storage."
"Good starting capacity and scalability."
"The most valuable features of PowerProtect DD are the immutable storage and the AI scanning."
"I like the different features. We work closely with Dell on different products and features, which is why we use them all."
"I am impressed with the tool's technical alliance with Veeam and Veritas."
"While the challenges posed by the difficulties were significant, they prompted the replacement of problematic components, resulting in the resolution of issues. Importantly, there were no substantial ongoing concerns. Regarding the overall performance, it has been consistently excellent."
 

Cons

"DD Boost."
"The price is also a disadvantage. Price is a disadvantage with the PowerProtect as it needs to be cheaper."
"The Data Domain solution appliance is quite expensive. It is on the higher side, but technically or functionally, there is no issue."
"We encountered data loss during the configuration process."
"Looking at Dell PowerProtect DD (Data Domain), there is a need for improvement, especially in terms of protection from cyber resiliency, cyber recovery, or man-in-the-middle attacks."
"The model 3330 may need improvement."
"The price for PowerProtect DD is not suitable for my customers. It is very high."
"EMC is very expensive for small customers."
"The product needs to improve performance while scaling out. It also needs to improve stability."
"Perhaps the most notable area for enhancement lies in the web interface for management. The current limitations in LDAP editing capabilities are not addressed in the UI, and I haven't observed any recent updates. It's possible that the new version of the DXI service incorporates improvements in the GUI, but I cannot confirm. While there is room for improvement in the current GUI, it remains a relatively minor issue. Overall, the system is comprehensive, covering aspects such as reports on latency and networking, leaving little room for additional enhancements in those areas."
 

Pricing and Cost Advice

"Dell PowerProtect DD's pricing is expensive, and there is no option for perpetual licensing."
"Pricing for this product could still be improved, though several years ago, its price was very high. When buying an IDPA product such as Dell EMC PowerProtect DD (Data Domain), you don't have to buy anything else, because you'll have an integrated solution: a data domain appliance plus software."
"It could be more competitively priced. Its licensing was for five years. Obviously, the support will get renewed at some stage, but that's it."
"The product is expensive."
"The price may be a bit higher than other products in the market, but you will receive ten out of ten support with next-business-day delivery on parts' availability."
"Users have to pay a capacity-based licensing fee for the solution."
"There are many options in the pricing structure which can cause some confusion and necessitate the purchase of additional licensing."
"The pricing is cost-effective for the solution"
"I do not oversee this aspect, as pricing is contingent on factors such as volume, technical specifications, and the desired features. Consequently, I lack information on the pricing details and structure."
