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 deduplication feature is the most valuable part of the solution."
"This solution has a feature called Domain Boost, which allows for source deduplication and compression."
"The licensing model is the most valuable aspect of Dell PowerProtect DD"
"Dell PowerProtect DD is a stable solution."
"The stability is excellent."
"Deduplication and compression are the best features of the solution, which are popular and very effective."
"Data Domain is an excellent repository that's compatible with a lot of different solutions. Even Veeam Backup recommends sending backup to Data Domain. Space optimization is great. Currently, it guarantees 50-to-1 compression of the application in the same device. In all these years, I never had a client who was unsatisfied with Data Domain. It is a solid appliance with VMware integration, instant access to restore and search, and analytics."
"It's deduplication and faster recovery that are the key features."
"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

"The software from Dell that can be used to operate Data Domain needs to have enhancements made to the user interface. It is too complex."
"We encountered data loss during the configuration process."
"The price could be a little cheaper than it is now."
"The pricing model needs to be improved."
"EMC is very expensive for small customers."
"They're scalable."
"Dell PowerProtect DD (Data Domain) is expensive. Also, it has a sort of a big physical footprint that data domains have, and that's part of the problem."
"The only problem is that it's more expensive than any other vendors available in the market."
"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."
"The product needs to improve performance while scaling out. It also needs to improve stability."
 

Pricing and Cost Advice

"The product is expensive."
"The price of the backup appliance is slightly expensive. Compared to other vendors, the pricing will be slightly higher."
"Becoming more expensive."
"Pricing is related to size. A lower range solution might be about $33,000. My customers use higher range versions with a price of around $100,000. That's the price for both the hardware and software."
"This is one of the more expensive backup solutions on the market."
"We usually buy products at the end year, and the license is included."
"The approximate license cost for Dell PowerProtect DD (Data Domain) is around 5,00,000."
"I can't remember what the license costs are. They might be paid monthly or every two months."
"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."
