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 integration of Dell PowerProtect DD (Data Domain) with leading backup applications within the infrastructure is very good."
"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."
"Dell PowerProtect DD’s most valuable feature is data deduplication."
"We have never had any issues with Data Domain. It has been stable."
"The solution allows us to take a huge number of backups, and the footprint is quite small."
"We have found the product to be scalable."
"I like Data Domain as a protocol for data backup."
"The most valuable feature is the performance because you can back up data really quickly."
"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

"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 price for PowerProtect DD is not suitable for my customers. It is very high."
"We encountered data loss during the configuration process."
"Technical support needs improvement."
"DD doesn't have Intel's air gap technology."
"They should reduce the CPC cost to customers. The product is becoming very expensive."
"We have had deduplication and replication issues. When we used another backup software we noticed that it didn't have the same issues."
"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 price is really high compared to other vendors. The licensing cost is huge. Normal, mid-tier companies or small-scale companies wouldn't be able to afford it easily."
"It is expensive, but the performance and deduplication cover for the cost."
"Becoming more expensive."
"If we do not move to the cloud solution and stay with our on-premise version we will miss some new features."
"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"
"We usually buy products at the end year, and the license is included."
"Dell PowerProtect DD's pricing is expensive, and there is no option for perpetual licensing."
"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."
