Comparison Results: PowerProtect DD is the winner in this comparison. It is powerful and secure with a proven ROI. StoreOnce does come out on top in the ease of deployment category, however.
"I like Data Domain as a protocol for data backup."
"The solution's most valuable feature is the integrated deduplication function."
"It works within backup windows and has got good deduplication."
"Dell PowerProtect DD’s most valuable feature is data deduplication."
"It's very competitive in terms of the price and technology. Also, the development team continuously makes updates. The data reduction feature is very useful."
"Stable and scalable suite of solutions with deduplication, apart from data protection, storage, and backup."
"The tool's performance is very good. DD Boost can improve its performance and backup."
"The deduplication feature is the most valuable part of the solution."
"HPE StoreOnce has high performance."
"The valuable feature is the ability to work with the Veeam software to reduce the backup windows."
"It results in more efficient storage utilization, cutting capital expenditure in half."
"The most valuable features are the deduplication and compression capabilities."
"The scalability is very good."
"The speed and deduplication ratio are two of the most valuable features of the solution."
"HPE StoreOnce is an easy-to-use tool."
"The initial setup is simple."
"DD Boost."
"When you use Data Domain, you have to have at least 20% free space so it can work properly. Sometimes we struggle with that, because we wanted to use all the free space, but then Data Domain becomes really slow. I understand that 20% is needed to process all the data, and doing the duplication and compression and all that, but it would be a big improvement if they did not require that 20%, because it is just too much to have available."
"They're scalable."
"DD doesn't have Intel's air gap technology."
"I would like to see integration with public cloud."
"Its management can be improved."
"The usage of this solution is a bit difficult to develop processes, and it takes a long time to market permits."
"The price could be improved."
"They could provide more options for storage capacity."
"Its customer service could be faster."
"This product would be improved with the inclusion of more features to security or WORM."
"The repository should have an extension to connect to the cloud and deposit the backups."
"The appliance doesn't have the global deduplication, it has StoreOnce deduplication. It does not deduplicate across the appliance, it will deduplicate in one particular store. With the global deduplication, I could store more data."
"When it comes to upgrading, it always goes block-wise. One block is 48 TB raw capacity. It would be good if they can include a smaller capacity for SMB customers. Currently, it is not possible to increase in a smaller capacity. You have to buy the exact same unit. It would be great if they can provide a smaller next block. There are around 20 hard disks, and it would be really helpful if we can add 10 hard disks initially and 10 hard disks later."
"HPE StoreOnce Backup to Disk (BTD) is not a good backup solution for NAS devices. It does not have a dual controller, so if one controller fails, the entire system will go down."
"The GUI and its user-friendliness have some room for improvement."
