Executive SummaryUpdated on Nov 5, 2024

HPE StoreOnce and Dell PowerProtect Data Manager are prominent in the data deduplication and data management market. While both present strong features, HPE StoreOnce seems to have the upper hand due to its scalable deduplication technology and seamless integration with existing HPE infrastructure.

Features: HPE StoreOnce offers flexible deduplication locations, allowing deduplication at the client, backup appliance, or media servers. It integrates well with existing HPE solutions like 3PAR and Data Protector. The product enables significant storage savings, reducing backup data storage by up to 95%. Dell PowerProtect Data Manager supports robust protection for container and Kubernetes environments. It provides an integrated platform for data protection and offers high flexibility with powerful backup and recovery features.

Room for Improvement: HPE StoreOnce could enhance its deduplication algorithms and improve integration with third-party applications. Users also want an easier setup process and better reporting options. Dell PowerProtect Data Manager needs to improve first-level support, expand integration capabilities, and refine its user interface. Streamlining management across hybrid infrastructures is also desired by users.

Ease of Deployment and Customer Service: HPE StoreOnce is typically deployed on-premises with some hybrid cloud usage. Its customer service is positive but can improve in response times. Dell PowerProtect Data Manager also sees primary on-premises deployment with hybrid cloud options. While having a good support reputation, there is a call for more integration options and increased flexibility. HPE's broader support services potentially offer faster issue resolution.

Pricing and ROI: HPE StoreOnce is considered expensive, mainly due to licensing and necessary capacity. Despite operational savings, users desire lower upfront costs and clearer pricing structures. Dell PowerProtect Data Manager is perceived as competitively priced with flexible licensing models based on storage needs. Both solutions present strong ROI, particularly in operational efficiency and storage savings.

Streamlined VM protection has improved recovery speed and strengthened data security

The specific features and functionalities I find most beneficial in Dell PowerProtect Data Manager include good integration with other Dell products, such as Dell Data Domain, which makes it a very good use case for environments that already have Dell Data Domain or any other Dell products. My impression of Dell PowerProtect Data Manager's dashboard interface is that it is good, easy to use, and quite interactive, so there are no major issues there. The deduplication feature of Dell PowerProtect Data Manager has allowed me to reduce or save some 15% of storage compared to what I was using earlier.

Naguib Wasef

HPE Product Manager at a tech services company with 51-200 employees

Collaborate effectively with partners and benefit from robust data management capabilities

The functions of HPE StoreOnce that I find most valuable are its deduplication and replication options. These features save data and reduce the size of data significantly. If the actual size for backup data is 100 terabytes, using StoreOnce, it will be around less than 10% of the original size due to the 1 to 10 deduplication ratio. So, compression and replication are critical features I appreciate. Additionally, adaptive backup and restore capabilities of HPE StoreOnce are indeed very helpful functions. As I know from my technical team, the process is very easy for end users because the GUI and user experience with StoreOnce are straightforward. They can restore their backups at any time. An important feature of StoreOnce is that they can reserve an amount of storage capacity as protected capacity for a limited time, safeguarding their data against intrusion and other interactions. Based on feedback from customers, StoreOnce is regarded as a highly useful solution for backup. I am satisfied with the security aspects of HPE StoreOnce, but it's crucial for any company to maintain a multi-layer security approach. Starting with a firewall is essential for maintaining their environment. Additionally, security features on StoreOnce are useful. I believe that no company should rely solely on one layer of security; they should adopt a multi-layer security strategy that begins at the network level and extends to their internal solutions.
