Provides backups, including long-term retention with increased uptime and compatibility
I was looking for a virtual edition, and that is now available. Many customers struggle to find a solution for ransomware protection, but we can set up an enterprise recovery vault for that purpose. These features are now part of Dell's overall offering. The solution has matured, and while I don't criticize technology, most of our technical and business requirements are met with the Data Domain storage solution. We can meet customer requirements easily with Data Domain. Some feedback has been received from our operations team. There’s always room for improvement. For instance, there may be suggestions regarding enhancements to the reporting dashboard

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

"We have found the product to be scalable."
"The most valuable feature of Dell PowerProtect DD (Data Domain) is its deduplication capability."
"I like Data Domain as a protocol for data backup."
"I find the data to be most valuable."
"The most valuable features of Dell PowerProtect DD are reduplication and compression. It provides a lot of data savings for backups. Additionally, the Dell PowerProtect DD solution offers a bundled backup software and storage option. If desired, users can also connect to cloud technology to create an additional copy of their data in the cloud. This solution supports synchronization with various cloud vendors, including Azure and AWS."
"The most valuable features of Dell EMC PowerProtect DD are the duplication security and uptime."
"The most valuable feature is the inline data deduplication."
"It is stable. I would rate the stability of the solution a nine out of ten."
"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

"The price could be improved."
"We have some problems with backing up on the Power Platform. PowerServer is an IBM product, and it forces us to back up over LAN, which is not suitable for us."
"Improvement is needed in terms of telemetry and high availability as the high availability feature is only present in the higher models of Dell PowerProtect DD (Data Domain)."
"I would like to see integration with public cloud."
"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."
"The downside of PowerProtect's flexibility is that you have so many options. It can be a little confusing. It's like having a car with too many buttons on the dash. You can do so much with it, but it takes some time to learn what everything does."
"The pricing could be lower."
"The only problem is that it's more expensive than any other vendors available in the market."
"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

"If we do not move to the cloud solution and stay with our on-premise version we will miss some new features."
"The cost is expensive."
"We usually buy products at the end year, and the license is included."
"The pricing is cost-effective for the solution"
"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."
"I can't remember what the license costs are. They might be paid monthly or every two months."
"The approximate license cost for Dell PowerProtect DD (Data Domain) is around 5,00,000."
"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."
"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."
