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 most valuable feature of Dell PowerProtect DD (Data Domain) is its deduplication capability."
"We are very satisfied with this solution. It's easy to use and efficient."
"The most valuable features of this product are its guaranteed reliability and its duplication capability."
"The feature that I have found most useful is its data duplication."
"Short backup window has made a difference in the way my organization functions."
"The backup is very secure. The deduplication using EMC is very good. We are able to make systems and handle random cloning. EMC is a very stable solution for making backups."
"I find the data to be most valuable."
"When utilizing Dell PowerProtect DD for backup systems, Data Domain offers fast performance with low latency, providing high throughput for quicker backups compared to other vendors."
"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."
"I am impressed with the tool's technical alliance with Veeam and Veritas."
 

Cons

"Dell PowerProtect DD could improve by having better integration with other backup solutions."
"EMC is very expensive for small customers."
"The firmware upgrades could be simplified. I'm in the process of struggling to upgrade right now."
"Data Domain lacks compatibility with fiber channels and tapes. We can't use it with a tape library. That's an issue in Latin America sometimes because a lot of clients still use tapes for budget reasons. Maybe they have a lot of archives. In North America and Europe, they do a lot of archiving, but they use the cloud more than we do. Sometimes we have to put together a Frankenstein where we connect another server to the tape library and send all the data there."
"They should reduce the CPC cost to customers. The product is becoming very expensive."
"We encountered data loss during the configuration process."
"I would like to see integration with public cloud."
"The pricing could be better, but it's still not too expensive."
"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

"The cheaper device costs around $70,000."
"The price of the solution and support for Dell PowerProtect DD is expensive. We have customers that cannot upgrade to a newer version of the solution because the support is too expensive."
"The product is expensive."
"If we do not move to the cloud solution and stay with our on-premise version we will miss some new features."
"The approximate license cost for Dell PowerProtect DD (Data Domain) is around 5,00,000."
"On a scale where one represents high price, and ten represents low price, I rate the solution a five, which means that the solution is of medium pricing."
"This is one of the more expensive backup solutions on the market."
"The cost is expensive."
"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."
