Executive SummaryUpdated on Nov 5, 2024

HPE StoreOnce and Dell Avamar are competitive contenders in the data protection solutions market, both with strong deduplication capabilities. HPE StoreOnce stands out for its high-performance deduplication and flexible deployment options, while Dell Avamar impresses with its robust integration capabilities and effective source-side deduplication.

Features: HPE StoreOnce offers high-performance deduplication, flexible deployment options that include deduplication at the client, backup appliance, or designated media servers, and effective management of network bandwidth. Dell Avamar provides strong source-side deduplication, robust integration with VMware and Data Domain, and excellent virtual environment backup capabilities.

Room for Improvement: HPE StoreOnce requires enhancements in deduplication algorithms, better integration with third-party apps, and a more intuitive setup and learning process. Improvements in scheduling and cloud integration are also desired. Dell Avamar needs a better user interface, easier cloud platform integration, and refined reporting and expandability to adapt to evolving data environments.

Ease of Deployment and Customer Service: HPE StoreOnce receives praise for responsive and effective customer service and hands-on support, though deployment options focus mainly on on-premises with limited cloud solutions. Dell Avamar, while appreciated for deployment assistance, faces criticism due to complex setup and support, needing better customer engagement and problem resolution strategies.

Pricing and ROI: HPE StoreOnce is seen as expensive with a complex pricing structure but offers scalability and improved ROI over time. Dell Avamar shares similar cost perceptions but is competitive in the enterprise sector. Its flexible licensing options make it attractive to medium to large enterprises despite some users feeling the features do not justify the price. Both solutions offer significant ROI by reducing reliance on tape storage, optimizing backup operations.

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.
