We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
"The technology has been very useful. There are lots of features on offer.""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.""Stable and scalable suite of solutions with deduplication, apart from data protection, storage, and backup.""Good starting capacity and scalability.""The features that I have found most valuable with Dell EMC PowerProtect DD are its deduplication feature and its DD Boost protocol for fast transfer, which is amazing.""We are very satisfied with this solution. It's easy to use and efficient.""Data Domain is an excellent repository that's compatible with a lot of different solutions. Even Veeam Backup recommends sending backup to Data Domain. Space optimization is great. Currently, it guarantees 50-to-1 compression of the application in the same device. In all these years, I never had a client who was unsatisfied with Data Domain. It is a solid appliance with VMware integration, instant access to restore and search, and analytics.""The most important feature is the level of data compression provided by Dell EMC. It's a leader in data compression and deduplication, and the level of compression isn't available with any other vendors in the market."

"The most valuable feature of HPE StoreOnce is the virtual drive.""The initial setup is one of the most user-friendly B2B user solutions. It's good, it's easy. Deployment usually takes less than one day. You only need one person for deployment and maintenance.""HPE StoreOnce has high performance.""I like the tool’s deduplication feature. We get a ratio of 9:1 for deduplication. The product is also Linux based. Last year, our organization faced some virus attacks. However, the backup was safe because of the product being a Linux version. HPE StoreOnce is a secure product.""HPE StoreOnce works well, it is stable.""Has very good deduplication and encryption features.""The scalability is very good.""It is a very scalable solution."

"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.""It helps if you have in-depth knowledge in order to use it correctly.""They need to make migration easier.""The size and scale of the product are limited and could be improved.""They still have hardware different from the software.""Dell PowerProtect DD could improve by having better integration with other backup solutions.""I would like to see integration with public cloud.""I would like to see some kind of integration with the ransomware in the next release."

"The product's price could be better.""improvement? HPE StoreOnce has a limitation with respect to controllers. Other tools offer more than one controller. I feel that the high availability of the view controller should be redundant. The tool’s control and UI part should be improved and made more advanced. The feature that helps with the manual movement of tapes should also be improved.""The setup phase is not so simple that an end user can plug and play to make it operational.""The user interface of HPE StoreOnce should be more user-friendly. Additionally, the configuration and troubleshooting could be better.""One item I wanted to see is SSD drives as a cache, and that was, for a time, still lacking in StoreOnce, however, they have done it now. It's not available yet, however, it will be shortly.""HPE StoreOnce could improve the capacity support.""The solution should continue to refine its integration capabilities. I also see they are starting to use cloud integration as well, which is good, but they should do more to integrate with it.""Its customer service could be faster."
