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

Quotes from Members

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

Pros

"It's deduplication and faster recovery that are the key features."
"I like Data Domain as a protocol for data backup."
"Dell PowerProtect DD is a stable solution."
"The most valuable feature is the performance because you can back up data really quickly."
"The most valuable features of Dell EMC PowerProtect DD are the duplication security and uptime."
"The most valuable feature of Dell PowerProtect DD (Data Domain) is its deduplication capability."
"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."
"The most valuable features of the solution are recovery point, compression, and deduplication."
"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 could improve by having better integration with other backup solutions."
"The firmware upgrades could be simplified. I'm in the process of struggling to upgrade right now."
"The pricing could be better, but it's still not too expensive."
"DD doesn't have Intel's air gap technology."
"The only problem is that it's more expensive than any other vendors available in the market."
"We have had deduplication and replication issues. When we used another backup software we noticed that it didn't have the same issues."
"It can probably have integration with other OEMs. It should also have more features for ransomware protection."
"If I were a manager for this infrastructure, I would look into load balancing for cost, maintenance after sale, and improving Dell PowerProtect DD."
"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 approximate license cost for Dell PowerProtect DD (Data Domain) is around 5,00,000."
"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."
"The cost is expensive."
"The yearly subscription is very affordable for our customers, but the price could be a little cheaper overall."
"This is one of the more expensive backup solutions on the market."
"The cheaper device costs around $70,000."
"I can't remember what the license costs are. They might be paid monthly or every two months."
"The solution is expensive. However, if you pay less you receive less, it is cost-effective."
"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."
