Featured Reviews

Faisal_Zia - PeerSpot reviewer
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.
Andrew Mcbeath - PeerSpot reviewer

AmarpreetSingh - PeerSpot reviewer
Optimal data security and management achieved with smooth deployment and strong support
I plan to expand the number of users for Rubrik in the future. Currently, I have approximately 10 to 12 customers on Rubrik, as we are partners to Rubrik and a service provider, SIS. I am working with large to medium organizations, not small ones. Regarding Artificial Intelligence, Rubrik is in the initial phase, and I am expecting more from them. I can give them seven out of ten for their improvements in that area. I would recommend Rubrik to other organizations because it is easy to install, easy to manage, and very compact in terms of a solution, with good support from Rubrik. These features allow it to match from small scale to large scale customers very easily. The number of people who usually take part in maintenance from my side depends on the customer size. For large customers, we involve four to five people, but for small customers, one person is enough. I rate Rubrik eight out of ten.
