Provides seamless backup integration and long-term reliability for enterprise data protection
The price is quite high; this product is not considered cheap. Additionally, if you use higher availability boxes, they also come at a premium price. However, they provide business continuity, which is the main reason why companies invest in this solution. Tape is slow; when restoring several virtual machines or databases amounting to several terabytes, Dell PowerProtect Data Domain represents the fastest and most reliable solution, ensuring great integration with backup software. If a customer has limited budget constraints, they may opt for cheaper external storage comprised of just a bunch of disks and utilize it for backup, as backup is not a business-critical service. However, I see great value in Dell PowerProtect Data Domain because it is fully automated, features great integration with backup software, and provides good value for money. I would rate software support as a ten, while I would give hardware support a seven. I never give any product a perfect score; I think Dell PowerProtect Data Domain deserves a nine. The only minor problems are the certificate issue and the price. These certificate issues are quite rare and mainly arise when we forget to restart and upgrade the box for several years.

Expert Backup at a tech services company with 201-500 employees
A virtual deduplication backup appliance that protects physical and virtual data across remote sites, the datacenter and cloud deployments
Given its ease of use and management, I believe there are no specific caveats that users need to be aware of during the setup of DXRIS for backups. The process was straightforward, and I did not encounter any challenges or issues. As for a rating on a scale of one to ten, with one being the worst and ten being the best, I would rate the Quantum DXI Series a nine. My deduction is primarily influenced by personal preferences, particularly regarding the user interface and it is a highly commendable system, I would rate it a solid nine out of ten.

Quotes from Members

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

Pros

"The specific algorithms of backups of the data deduplication are very good."
"Fast backup for complex and huge size data."
"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."
"Dell is more stable than any other device."
"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."
"EMC is under the Dell technologies portfolio, and you've got one of the best technical support teams looking out for you."
"One of the most valuable features is that it looks for the deduplication, which can reduce the amount of the data."
"The most valuable features of PowerProtect DD are the immutable storage and the AI scanning."
"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 price is also a disadvantage. Price is a disadvantage with the PowerProtect as it needs to be cheaper."
"The initial setup is complex."
"The price of the product is high."
"The size and scale of the product are limited and could be improved."
"The price could be improved."
"DD doesn't have Intel's air gap technology."
"The licensing is not cost-effective, and the pricing could be better."
"The last downtime for upgrading the model 9410 took a long time, approximately two hours, which could be bad for production environments."
"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

"In Naira it was twenty-five or twenty-seven million (approximately $75,000 USD) for the implementation and maintenance cost for three years."
"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."
"The product is expensive."
"We usually buy products at the end year, and the license is included."
"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."
"There are many options in the pricing structure which can cause some confusion and necessitate the purchase of additional licensing."
"Becoming more 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."
"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."
